As preferably, the cable channel cover plate that the utility model adopts comprises link, the both sides wing tip adjacent with link and the free end relative with link; Described link is flexibly connected with cable trough abutment wall by stainless steel bearing hinge and expanding tube screw.
As preferably, the flank end adjacent with link that the utility model adopts is provided with breach.
As preferably, the flank end adjacent with link that the utility model adopts is provided with breach or is provided with breach on two flank ends.
As preferably, when two flank ends that the utility model adopts are provided with breach, described cable channel cover plate entirety is in dumbbell shape structure.
As preferably, the cover plate that the utility model adopts can also comprise the rhone being arranged on cable trough abutment wall top by side turn over tunnel cable ditch.
As preferably, the degree of depth of the rhone that the utility model adopts and width are 5cm.
As preferably, the cable trough base that the utility model adopts and cable trough abutment wall all adopt C25 concrete to carry out cast and are formed; Described cable channel cover plate adopts the prefabricated formation of lightweight aggregate concrete.
The utility model comparatively prior art is compared, and has the following advantages and beneficial effect:
Because lightweight aggregate concrete has the advantages such as intensity is high, density is low, cost is low, the fields such as traffic, electric power, building are widely used in, therefore, the utility model adopt lightweight aggregate concrete cover plate and stainless steel bearing hinge can give cable channel cover plate easily to turn on one's side, the performance of lightweight; Required cost is lower, workable, effectively can avoid dismantling cover plate cracking that cable channel cover plate causes, broken in tunnel maintenance maintenance process, tunnel maintenance maintenance work is in progress smoothly, efficiently; Simultaneously, the utility model arranges rhone on cable trough abutment wall top, effectively can prevent percolating water in tunnel from flowing in cable trough, avoid it to be oxidized the burn into of tunnel cable, ensure the Long-Term Properties of tunnel cable, there is higher economic benefit and social benefit.
