A connection device for bridge deck and subgrade of pile-slab structure

Abstract

The invention relates to a connection device of a pile slab structure deck slab and roadbed, and relates to the novel technical field of expressway construction. The device comprises a plain concrete under layer, a cushion block, a sill plate, original roadbed, a drainage net, a polyurethane pouring crack, a present watering block, a polyester fibre cloth and a bituminous concrete mat formation; the cushion block is arranged on the outer side of the upper portion of the plain concrete under layer, the sill plate is fixedly arranged on the upper side of the cushion block, and the original roadbed is arranged on the inner side of the plain concrete under layer; a back watering overlapping joint band is arranged between the sill plate and the original roadbed, the drainage net is arranged on the outer side face of the original roadbed, and the polyurethane pouring crack is formed in the outer side of the drainage net; the present watering block is poured among the cushion block, the sill plate and the polyurethane pouring crack, the polyester fibre cloth is arranged on the upper side of the sill plate, the present watering block and the original roadbed, and the bituminous concrete mat formation is laid on the upper side of the polyester fibre cloth. The connection device of the pile slab structure deck slab and the roadbed is better in integrality and simple in construction, saves the land, has little influence on the surrounding environment, and is high in assemblage construction degree, short in construction period and good in economy.

Description

[0001] Technical field: [0002] The invention relates to the new technology field of expressway construction, in particular to a connection device for a bridge deck of a pile-slab structure and a roadbed. [0003] Background technique: [0004] With the development of modern transportation technology and information technology, and the accelerated pace of work and life, people's calls for convenient and fast travel are getting louder and louder. In recent years, my country has increased the speed of infrastructure construction, but with the increasing scale of urbanization and population growth, the corresponding traffic volume and car ownership have grown rapidly, and urban traffic congestion and environmental protection problems have become more and more prominent. Large-scale expressway reconstruction and expansion is imminent. [0005] There are many problems in the conventional reconstruction and expansion methods, such as difficulty in land acquisition, large amount of f...

AI Technical Summary

Problems solved by technology

[0005] There are many problems in conventional reconstruction and expansion methods, such as difficulty in land acquisition and large amount of filling; long construction period and large social impact; polluting the environment, not being environmentally friendly, etc.

Common solutions include: pile-slab retaining wall, half-mountain and half-bridge, pile-slab structure, etc., but all have defects such as limited scope of application, high cost, and low degree of assembly
