Control cabinet maintenance
1. Disconnect the power supply, check the cabinet of the control cabinet for reliable grounding, and make the grounding resistance not more than 4Ω.
2. There are different voltages on the control cabinet (DC 110V; AC single-phase 220V; three-phase AC), the circuit must be separated during maintenance to prevent short-circuit accidents.
3. All electrical switches on the control cabinet should be flexible and reliable, with no significant noise. There should be no looseness at the junction of the connecting wire and the terminal. The wire at the junction of the moving contact cable should be free of breakage.
4. Use a soft brush or blower to clear the screen insert and the dust of all the electromagnetic switch parts, and check the state of the electrical switch contacts in the control cabinet, the contact situation, the insulation of the outer surface of the coil and the action of the mechanical parts are reliable.
5. When replacing the fuse, the fuse current should match the current of the loop.

Geogrid


The Geogrid including Polyester Geogrid, Fiberglass Geogrid, Steel Plastic Composite Geogrid and Plastic Geogrid. 

The geogrid is a major geosynthetic material. Compared to other geosynthetic materials, it has unique performance and efficacy. Commonly used for reinforcement of soil structure or reinforcement of composite materials.

The uses of geogrid: It is suitable for embankment and embankment reinforcement slope protection tunnel wall reinforcement large airport parking lot wharf cargo yard and other permanent bearing foundation reinforcement.


The feature of geogrid:

The high strength creep can adapt to all kinds of environment soil, and can satisfy the use of high grade highway retaining wall.

It can effectively improve the locking and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.

More suitable for deep-sea operations, embankment reinforcement, fundamentally solve the other materials do stone cage due to long-term erosion by the sea caused by low strength, poor corrosion resistance, short service life and other technical problems.

It can effectively avoid the construction damage caused by the crushing and destruction of machinery and tools in the construction process.
