Precautions For DW Single Hydraulic Prop Working Face Wood Stack

The DW single hydraulic prop is a constant resistance prop, which can be used with various top beams or as a main pillar. It can be used for general mechanized coal mining or blasting working face support item, also can be used for comprehensive mechanized coal mining face end support or other temporary support. Then let's follow me to analyze the precautions for its special support wood stack.

DW single hydraulic prop working face

1. Do not use round wood, three-edged wood, mixed seeds, rotten wood, damaged or deformed wood for piling.

2. The wood stack should be made of square or triangular wood of the same size. If the length of the material is not uniform, it is required to align it along the side of the work surface.

3． The level of the wooden stack is consistent with the inclined surface of the working surface, and the uphill angle should be consistent with the uphill angle of the basic support.

4． The contact points of the layers of the wood stack are up and down in a straight line.

5． The length of the wooden stack should not be less than the row spacing, and should generally be not less than 1.2 meters.

6. The length of the wooden piles after being overlapped shall not be less than 0.15 meters, and they shall be 90 ° to each other.

7. When stacking wooden stacks, check the support at that place first. If the support is damaged or incomplete, handle it properly before setting up the wooden stack.

8. Erecting the wooden stacks more than 15 meters ahead of the post.

9. When stacking a wooden stack at a fault or crack, the wooden stack is erected on both sides of the fault or crack, and it is not allowed to play only one wooden stack directly below it.

Disassembly Process Of Single Hydraulic Prop

As we all know, the single hydraulic prop is a new environmentally friendly support equipment, which can be used with metal hinged roof beams for general mining and artillery using working face support roofs and fully mechanized working face support ends, or it can be used alone Used for point support or other temporary support. The single hydraulic pillar needs to be cleaned after use, so it will be disassembled if it is cleaned. So how to disassemble correctly is very important. Let ’s understand how to replace damaged parts and replace all seals and plastic parts. .

Single hydraulic prop disassembly process:

1. First, clean the surface slime and coal dust.

2. Clamp the pillar on the workbench or vise, punch out three elastic cylindrical pins with a punch, remove the top cover, unscrew the vent valve with a wrench, and release the hydraulic oil in the pillar cavity.

3. Use pliers to pull out the connecting wire in the handle body and withdraw the handle body from the cylinder body; open the unloading valve and pull out the live cylinder from the oil cylinder.

4. Remove the screw with a wrench when removing the live cylinder, remove the spring washer and steel ball, install the crank on the crank, and shake the piston to remove the piston to remove the handle.

5. Disassembly of the vent valve: Remove the end cover, take out the steel ball, use a flat-blade screwdriver to unscrew the plug, remove the spring, the valve core and the ejector rod, and remove the ejector rod from the valve cartridge.

Disassembly Process Of Single Hydraulic Prop

6. Disassembly of the piston: Pull out the filter screen and guide ring by hand, and use a screwdriver to remove the y-shaped ring and the leather bowl relief ring. Use a flat-blade screwdriver to unscrew the screw sleeve and take out the check valve spring and steel ball. Use a copper or bamboo stick to lightly tap the steel ball, and the one-way valve seat withdraws together with the supporting spring and the steel ball. The special tool expansion cone is installed in the pump sleeve, and the cone sleeve is twisted with a wrench to increase the outer diameter of the expansion ring and press it tightly on the pump sleeve. The impact of the rising cone caused the pump sleeve to cut the 32 × 3.5 seal ring in the piston, and the rising cone was pulled out of the piston together with the pump sleeve. Use a wrench to turn the cone sleeve in the opposite direction to make the rising cone exit from the pump sleeve.

7. Use the retaining ring pliers for the hole to remove the unloading device, the retaining ring for the hole, and the hole plug. Use pliers to remove the cotter pin on the unloading device. Withdraw the square pin, cam and unloading ring, clamp the large flat-blade screwdriver in the groove of the safety valve and valve sleeve, cover the socket wrench on the unloading valve seat, unscrew the unloading valve seat, and carefully exit the safety with a steel rod valve.

8. Removal of the safety valve: Clamp the safety valve on a vise, use a pressure screwdriver to remove the pressure adjustment screw, use tweezers to remove the safety valve spring and hexagonal guide sleeve, and remove the valve needle. Remove the connecting screw with a wrench from the other end, install an old guide sleeve on the valve seat, and exit the valve seat with an iron rod (with a tapered hole in the center).

The above is the disassembly process of the single hydraulic prop. The correct disassembly method is a protection for the equipment. Engineers of Shandong China Group hope that everyone has a certain understanding of the removal of the single hydraulic prop. If you have a single hydraulic prop For needs, you can always contact us.

Reinforced Concrete Protective Layer Thickness Detection

Reinforced protective layer is a routine and mandatory inspection item in reinforced concrete structures. In a broad sense, the steel bar protection layer is the part of concrete that protects the steel bar and prevents the steel bar from being exposed directly.

Each specification has a different definition of thickness, most of which is the distance from the outer edge of the steel bar (excluding the stirrups) to the outer surface of the concrete.

In addition to the quality of raw materials, the protective layer of steel directly affects the durability of concrete structures.

As we all know, concrete is directly exposed to the air, and carbonization occurs from the surface layer to the deep layer. When the carbonized layer contacts the reinforcing steel, it will cause corrosion of the reinforcing steel.

In addition to the reduced strength and performance of rusted steel bars, expansion will occur. The volume expansion coefficient of deep rusted steel bars can be above 1.7. The expanded steel bars will cause the surrounding concrete to crack and the protective layer of concrete to fall off, which will expose the steel bars and cause further rust.

The carbonization rate of concrete is about 1mm every two years, and a sufficiently thick protective layer can effectively delay the process of carbonization depth reaching the position of the reinforcement, which is also an important basis for determining the useful life of the concrete structure in the design.

The thickness of the protective layer is too small, which is a direct hazard. In the specification, the requirement of "minimum value of the protective layer of the reinforcing bar" is also specified. In the case of stressed concrete members such as beams and columns, if the thickness of the protective layer is too large, the concrete is prone to cracking, and air and moisture contact the steel bars through the cracks, which will cause the aforementioned steel bars to rust, expand, and fall a series of questions off the protective layer.

Therefore, the thickness of the protective layer should not be too small or too large, and should be within the range allowed by the specification. Therefore, in addition to the dimensional deviation inspection during the construction process, the thickness of the protective steel layer in the structural entity should also be inspected.

The verification check of the thickness of the reinforced concrete protective layer is to strengthen the quality acceptance of the concrete structure, truly reflect the quality indicators such as the position of the reinforced steel bar, and ensure the safety of the structure.

The detection of the thickness of the protective layer of the steel bar can be detected by the broken method and the non-broken method. Generally, the non-destructive method is used to reduce the workload, and if necessary, the partial damage method is used for calibration.

The following introduces the ZBL-R630  rebar detector produced by Shandong China Coal Group.

Preparation before testing

1. Look at the drawings and design documents to understand the thickness of the protective layer, the diameter of the reinforcing bars, the spacing and distribution of the reinforcing bars, the location of the embedded parts, etc., and make a record.

2. Determining the number of random inspections: According to the relevant provisions of the steel bar protective layer thickness detection in Appendix D of "Quality Inspection Standards for Water Transportation Engineering" (JTS257-2008), at least 6 reinforced bars shall be selected for the supporting walls, gate walls, etc. for testing. Each rebar should be measured at a representative location at 2 to 3 points.

3. Inspection items before the use of concrete rebar detector—

(1) Check whether the concrete reinforcing rebar detector is within the verification period of use, and check on the standard parts to verify whether the equipment is in normal use.

(2) Check the battery level. If the battery level is extremely low, the instrument will beep 3 times, and then the empty battery icon flashes in the lower right corner of the screen. At this time, you should immediately exit the detection interface, return to the main menu interface, and shut down. Otherwise, data will be easily lost or error.

On-site testing steps

The on-site detection technology is very important, which is related to the accuracy of the detection data. Taking the # 6 left lock wall of the lock room of a ship lock expansion and reconstruction project as an example, the detection steps are as follows:

1. The surface of the component needs to be clean, flat, free of dirt and plaster.

2. According to the drawings, design documents and on-site supervisors, there are no embedded metal parts at the measuring point that affect the testing data.

3. Select the range of the rebar detector, which is divided into two ranges. The first range is used in the case where the thickness of the protective layer to be tested is small; the second range is used in the case where the thickness of the protective layer to be tested is large.

4. Rebar detector parameter settings:

(1) Component number setting;

(2) Set the diameter of the steel bar to be tested, and the steel bar diameter of this component is 25mm;

(3) Set the thickness of the design protection layer of the tested steel bar, here is 50mm;

(4) Minimum thickness setting. When the value is set to a value other than 0, if the thickness of the protective layer of the measured steel bar is less than the set value, the instrument alarms and prompts, and does not display and store the measured protective layer thickness. This time the parameter is set to 0, so the function is turned off;

(5) Data correction. The use of this function cannot completely eliminate the influence of adjacent steel bars on the test results. No numerical correction is performed for this test.

5. Rebar detector reset: In the parameter setting interface, hold the sensor in the air, away from the ferromagnet, press the "back" key to enter the test interface, the rebar detector automatically performs the sensor reset operation, and the test interface screen prompts after about 3 seconds. The current thickness is displayed as "0", resetting is completed and the measurement waiting state is entered.

6. Determine the position, direction and thickness of the protective layer. To determine the direction of the reinforcing steel bar, it is necessary to avoid the interference of unrelated steel bars. When measuring the 6 # longitudinal steel bar in the left gate wall of the lock room, the horizontal bar is scanned first, and a survey line is arranged between two adjacent horizontal bars.

Then place the probe on the concrete surface to be tested, move the sensor at a constant speed in a direction parallel to the measured steel bar. As the probe gets closer to the steel bar, the scroll bar gradually increases, the signal value increases, and the current thickness value decreases. ; The thickness of the protective layer thickness of the steel bar is automatically locked when the probe passes over the reinforcing bar. Press the “Save” key to store the measured protective layer thickness value.

Performing a reset operation every 10 minutes or so during the test can improve the test accuracy.

7. Sorting of test results. The detected data can be output through the software that comes with the instrument, or it can be manually entered into the computer. After finishing, the component measured a total of 25 points, of which 3 failed points (both positive deviations), the pass rate was 88%.

Evaluation of test results

According to "Quality Inspection Standard for Water Transport Engineering" (JTS257-2008), the positive deviation of the actual thickness of the reinforced protective layer of cast-in-situ gate walls, retaining walls and other components should not exceed 15mm, and the negative deviation should not exceed 5mm. In each sampling test result, the maximum negative deviation of the unqualified points should not be greater than 7.5mm.

The standard for determining the solid steel protective layer thickness of major components is qualified: When the passing rate of all steel protective layer thickness testing is 80% or more, the test result is qualified;

When the qualified point rate is less than 80% but not less than 70%, the sampling test should be doubled. When the qualified point rate calculated based on the sum of the two sampling quantities is 80% or more, the test result of the thickness of the steel bar protection layer should still be determined as qualified . In summary, the thickness of the 6 # steel bar protection layer on the left gate wall of the lock chamber is judged as qualified.

Conclusion

Inspection of the reinforcing steel protection layer is only one of the inspection and acceptance items of the reinforcement process. To ensure that it is within the scope of the specification, it is necessary to make corresponding work on the steel bar cutting, installation, support and reinforcement, formwork assembly, and concrete pouring. Control can be said to be a microcosm of the quality of each component process.

The reinforced protective layer rebar detector is easy to operate and easy to carry, and the number of detections of protective layer indicators during inspections has increased year by year. However, in previous inspections, there were not many projects that could pass the inspection. Therefore, choosing a rebar detector with guaranteed quality is the first step to ensure that the engineering test is qualified.
