Temporary channel anti-skidding road surface for foundation pit excavation and construction method of temporary channel anti-skidding road surface

Abstract

The invention discloses a temporary channel anti-skidding road surface for foundation pit excavation and a construction method of the temporary channel anti-skidding road surface. The temporary channel anti-skidding road surface comprises a plurality of anti-skidding road surface units which are mutually connected, each anti-skidding road surface unit comprises a rectangular steel board, a plurality of splay steel blocks and flanges, the splay steel blocks are arranged on the steel board, the flanges are arranged on two sides of the steel board, the anti-skidding road surface units are connected into the road surface through circular rings penetrating through perforations at four corners of the steel board, the anti-skidding road surface units are fixed through pins horizontally penetrating through the circular rings, and a cement mortar surface layer is sprayed on the road surface. The construction method of the temporary channel anti-skidding road surface includes the steps: 'determining the width and the gradient of a road, building a foundation of the road, laying the anti-skidding road surface units, spraying the cement mortar surface layer, maintaining the road surface and the like'. The temporary channel anti-skidding road surface has the advantage that the road surface has fine anti-skidding effects, can prevent warping damage, and accordingly avoids overturn accidents caused by damage of road soil due to stress concentration and tire slip of an overload vehicle in the climbing process of earthwork transport.

Description

technical field [0001] The present invention relates to a non-slip pavement for temporary passages, more specifically, the present invention relates to a non-slip pavement for temporary passages used for the excavation of foundation pits for building construction and large-scale excavation of foundation pits such as subway stations and its construction method. Background technique [0002] Excavation and transportation of earthwork is the longest process in foundation pit engineering, which requires a lot of manpower and material resources. [0003] Most of the current temporary passages for foundation pit excavation and transportation outside are built by simple mechanical compaction or by laying asphalt concrete on the temporary road surface. [0004] For the former, because the temporary channel is easy to be crushed by heavy-duty vehicles, it often leads to rollover accidents; for the latter, due to the poor anti-skid effect, tires of heavy-duty vehicles often slip duri...

Problems solved by technology

[0004] For the former, because the temporary channel is easy to be crushed by heavy-duty vehicles, it often leads to rollover accidents; for the latter, due to the poor anti-skid effect, tires of heavy-duty vehicles often slip during the climbing process of earthwork transportation; Neither of them can be recycled, and the project cost is too high
