Construction structure and construction method of underground comprehensive pipe gallery and road

Abstract

The invention relates to a construction structure and a construction method of underground utility tunnel and road. The method comprises the following steps: PHC tubular pipes are constructed in the location of the underground utility tunnel, plain concrete piles are constructed on the road; a settling transition section is set at the one side of central dividing zone of the road adjacent to the underground utility tunnel preparing for construction; the plain concrete piles are constructed in the settling transition section, the spacings between the plain concrete piles in the settling transition section are smaller than the spacings between the plain concrete piles below the road; road embankment of the road is constructed, a geogrid is laid in the road embankment of the road, more dense concrete piles are arranged in the settling transition section to provide slow transition for the settling of the tunnel and the road, the settlement difference between the tunnel and the road is effectively adjusted and coordinated through cooperation with the geogrid so that longitudinal cracks of the road surface at the side wall of the tunnel are avoided.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction structure of an underground comprehensive utility gallery and a road and a construction method thereof. Background technique [0002] Underground comprehensive pipe gallery, also known as "common ditch", refers to the construction of public tunnels for centralized laying of municipal pipelines such as electricity, communications, radio and television, water supply, drainage, heat, and gas in the city's underground, and centralized management of large-scale comprehensive tunnels. Municipal infrastructure. The construction of underground comprehensive pipeline corridor is conducive to solving the problems of repeated excavation of road surface, dense overhead line network and frequent pipeline accidents caused by traditional underground direct buried pipelines. [0003] When the urban underground comprehensive pipe gallery is constructed simultaneously with the ...
