Expressway pavement structure capable of utilizing waste residues

Abstract

The invention provides an expressway pavement structure capable of utilizing waste residues, and relates to the technical field of pavement filling structures. The structure comprises a bracket; supporting plates are fixedly connected to the front end and the rear end of the top end face of the bracket respectively, the top end faces of the two supporting plates are fixedly connected to the front end and the rear end of the bottom end face of a top plate respectively, honeycomb-shaped grooves are formed in the top of the top plate, the honeycomb-shaped grooves of the top plate and the honeycomb-shaped grooves of the bracket are distributed in a staggered mode, the left end face of the bracket is fixedly connected with the right end face of the bracket A, eleven through holes are distributed in the middle of the top end face of the bracket A, and the distance between every two adjacent through holes is the same. According to cooperation of the full sealing frame A and the sealing frame B in each embodiment of the invention, compared with the prior art, overflow of waste residues can be limited when the upper end of the bracket is filled with waste residue materials. The problems that when the base course surface of the expressway is filled with waste, the waste scattering position is wide, secondary arrangement needs to be conducted in the laying process, and the consumed time is long are solved.

Description

technical field [0001] The invention relates to the technical field of pavement filling structures, in particular to a highway pavement structure utilizing waste slag. Background technique [0002] Expressway refers to the highway specially designed for high-speed driving of automobiles, which provides convenience for the connection between various cities. The structure of expressway pavement is usually paved in layers, that is, according to the requirements of use, stress conditions, soil foundation support conditions and natural factors. According to the different functions of each layer, the pavement structure layer can generally be divided into multi-layers such as surface layer, base layer, sub-base layer and cushion layer. When the base layer is established, it can be filled with waste residues to reduce construction costs. However, as far as the current high-speed pavement using waste slag is concerned, when the waste material is filled to the base layer of the highwa...

[0002] Expressway refers to the highway specially designed for high-speed driving of automobiles, which provides convenience for the connection between various cities. The structure of expressway pavement is usually paved in layers, that is, according to the requirements of use, stress conditions, soil foundation support conditions and natural factors. According to the different functions of each layer, the pavement structure layer can generally be divided into multi-layers such as surface layer, base layer, sub-base layer and cushion layer. When the base layer is established, it can be filled with waste residues to reduce construction costs. However, as far as the current high-speed pavement using waste slag is concerned, when the waste material is filled to the base layer of the highway, the waste material is scattered in a wide area, and it needs to be adjusted twice during laying, which takes time. longer
