Abstract

The invention provides a construction technology for preventing cement concrete pavement longitudinal joint edge gnawing, and relates to the field of road construction. The technology specifically comprises the following steps that when a cement concrete pavement is poured, after steel formworks on the two sides of a surface layer are fixed, oil is smeared on the upper half portions of the steel formworks, one half of a plastic film is attached to the steel formworks, the other half of the plastic film is laid on a lower bearing layer, then a tension rod is inserted to position the plastic film, a lateral blocking interface for concrete is formed, and concrete is poured. According to the technology, the plastic film is fixed through a tension bar, the working procedures are required in sequence, other technologies and working procedures of cement concrete pavement construction are not changed, the two working procedures of caulking by mixing cement mortar and removing caulking solidification materials after formwork removal are omitted, and more importantly, after traffic is open, the edge gnawing phenomenon of longitudinal joints in the middle of a road cannot occur.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a construction technique for preventing longitudinal seams of cement concrete pavement from gnawing edges. Background technique [0002] From the meaning of the word, the road is the infrastructure for various trackless vehicles and pedestrians; according to its use characteristics, it can be divided into highways, urban roads, country roads, factory and mine roads, forestry roads, examination roads, competition roads, automobile test roads, and workshop passages As well as school roads, etc., there were also post roads in ancient China. At present, road pavement is mainly divided into cement concrete pavement and asphalt concrete pavement. Wherein, cement concrete: refers to the general designation of engineering composite materials formed by mixing cement, sand, stone, etc. with water. Generally speaking, the term concrete refers to cement as cementing material, sand and stone...
