2, top plate separation tester:

(1) Using a bolt drill to drill the eye, the drill bit uses an alloy steel drill bit with a specification of Φ27 mm or Φ28 mm and a hollow hexagonal drill. Before hitting the eye, first knock on the top of the question, carefully check the top rock condition, find out the live rock and dangerous rock, and confirm the safety before starting work. The position of the eye should be accurate, and the top of the vertical roadway should be ensured that the top plate is naturally drooping. The drilling depth is constructed according to the anchoring depth of the anchor cable near the location. The drilling depth is 1m deeper than the anchoring depth of the anchor cable at the location.

(2) Push the deep base anchor into the hole with the anchor cable until the design position (same length as the anchor cable). After pulling out the anchor cable, pull the wire rope to confirm that the anchor is anchored firmly, and then the shallow base anchor. Push into the design position of the hole (same length as the anchor). After pulling out the anchor cable, pull the wire rope to confirm that the anchor is anchored firmly. Finally, push the white PVC sleeve of the separator to the hole and confirm that it is fixed to the top of the PVC sleeve and close to the top plate.

(3) Alignment scale: Align the two measuring point indicating scales with one end of the red sleeve, jam the rope, and cut off the excess steel wire rope.

(4) After the installation is completed, write down the initial value of the depth and base point scale.

(5) The top plate isolators must be installed by the technician on site.

(6) The top plate separation indicator should be numbered and listed for management.

The filling of the top layer indicator should be neat, clear and true. The suspension position is reasonable and facing the sidewalk for easy observation. The roadway construction unit must ensure that the separation meter and the card are clean and in good condition.

(7) The measuring tube in the deep and shallow part of the top plate is not to be trapped by other debris such as mesh, so as not to affect the monitoring of the top layer.

(8) The construction team must establish an observation table for the roof separation indicator. The account should be filled in by the on-duty inspection and acceptance personnel. The installation of the separation indicator is continuously observed for not less than 5 days. The duty team is responsible for implementation every day. The production mine pressure group will check the installation quality of the roof separation indicator from time to time, and review the readings of the top layer indicator.

1. Responsible person: The team technician monitors and records the roof separation meter in the construction roadway, fills in the roof separation layer management board, and is responsible for summarizing the monitoring data and filing. Other teams must observe at any time. In order to detect anomalies in a timely manner and deal with them in time to ensure safety.

2, monitoring frequency: the newly installed roof separator should be observed for at least seven consecutive days. According to the actual observation changes, the separation meter in the special area (the separation meter with faster reading value) requires the technician to perform every day. Detecting and recording, the top plate movement of the top plate in the safety zone requires weekly inspection and recording.

3. Monitoring method: The deep and shallow scale reading of the top plate isolating instrument is equal to the moving amount minus the initial value; when the roof plate sinks within the bolt support range, the scales of the deep and shallow base points of the top plate is different. When the roof plate sinks within the anchor cable support range and the top plate does not move within the anchor support range, the top plate separation layer only has a deep base point scale change. If the roof plate within the anchor rod and anchor cable support range sinks at the same time, the top plate The scale on the deep and shallow base points of the delamination meter changes, and the variation of the deep base point scale is the sum of the sinking amount of the top plate.

Third, ACLY-2 top plate separation indicator, CDY-3 top plate separation tester, WBT-10 top plate separation observation instrument new product



The technicians of the construction team analyzed and processed the monitoring data of the day, and found that the abnormality was reported to the production geological technology department in time, and the monitoring data was analyzed together with the relevant personnel of the technical team, and then reported to the chief engineer of the geology. The chief engineer presided over the analysis and based on the analysis results. Propose corrective measures and carry out rectification and implementation. The direct leader shall supervise and inspect the monitoring data of the roof separation tester every month, and issue a rectification notice to the existing problems; the team shall promptly rectify according to the standard when receiving the rectification notice.

Shutter Sound Barrier are acoustic fences designed to act as a Sound Barrier and screen vehicle noise from roads,highways, railways, residential areas, construction sites. 

Noise barriers help in absorbing the noise generating from vehicles on a heavy vehicular traffic area. Thus noise barriers have proven to be effective in absorbing noise and providing an excellent solution to subsidize noise for highway, residential areas near the busy roads, and also for schools, hospitals.
Materials: aluminum sheet, galvanized steel sheet .etc
Finishing:high-pressure electrostatic spray coating
Standard Height:2,000mm, 2,500mm, 3,000mm and space between poles 1,000mm, 2,000mm and 2,500mm. it is available upon customer request.
Features:
1. Absorptive and insulation type.
2. Minimum noise leakage due to special snap lock design.
3. High intensity and stability: special-made steel structure and aluminum material.
4. Safety: PC sun panel or double layers with pastern apply on the transparent insulation part to avoid hurting vehicle and others on case of incident.
5. Beautiful appearance, delicate workmanship, easy installation, low cost and long service life.
6. It has wide applications on express way, subway and industry noise control.
7. The light transmission of the sheet is quite good.
8. The weather resistant treatment of anti UV on the surface of the sheet prevents the resin from turning yellow by causing Ultraviolet ray.
9. The UV agent has chemical bond to change ultraviolet ray into visible light ,which has a stable effect on the photsynthesis of plants.
10. Temperature property: in the temperature from -40C to 120C, the product will not deform.
11. It is light in weight, easy to handle and drill,convenient for construction and procession .When cutting for installation ,it is not easy to be broken.
Applications:
1. Highway noise walls
2. Railway noise walls
3. Airport noise barriers
4. Security fence
5. Obscuration screens
6. Bridge and roof mounted noise barriers
7. Industrial noise control panels
8.Construction materials
9.School enclosures
