Trench cover

As an indispensable concealed engineering component in urban infrastructure,Trench covers are widely used in scenarios such as road drainage,power pipe galleries,and communication shafts.Its core function is to achieve rapid diversion of fluids such as rainwater and sewage and convenient opening of equipment maintenance channels while ensuring the safety of personnel and vehicle passage.

The working principle of the Trench cover is mainly reflected in its design structure and material characteristics,ensuring the normal operation and safe use of the ditch.The product design structure includes criss crossing flat steel and horizontal bars,which are formed as a whole through high-voltage resistance welding.This structural design enables the load to be evenly distributed to the surrounding support beams,thereby improving the bearing capacity.In addition,hidden beams or reverse beams will be installed at the corners of the trench and the junctions of the longitudinal and transverse trenches as supports for the bottom reinforcement,further enhancing the stability and bearing capacity of the structure.
The material characteristics of the trench cover plate are also an important component of its working principle.Its bearing capacity reaches 5 tons/square meter,which is 2.5 times that of traditional concrete cover plates.At the same time,its self weight is only about 40kg/square meter,greatly reducing maintenance difficulty.The polyethylene material trench cover plate is known for its excellent anti slip effect and compressive performance,which can effectively reduce accidental falls and maintain stability in high-intensity operations.
The working principle of Trench cover has evolved from the traditional"bearing+drainage"function to a system engineering that integrates mechanical optimization,functional integration,and environmental adaptation.
