Splicing structure for new and old roadbeds and pavements in highway engineering

Abstract

The invention discloses a highway engineering new and old roadbed pavement splicing structure, and relates to the technical field of highway engineering splicing structures, the highway engineering new and old roadbed pavement splicing structure comprises a strip-shaped base, a fixing plate and a pouring plate; a strip-shaped base is arranged on a roadbed between a new pavement and an old pavement through expansion screws, and four threaded holes are formed in the strip-shaped base at equal intervals in a penetrating mode. The fixed plate is fixed on the outer side cross section of the old pavement through expansion screws; a pouring plate is poured and fixed in the inner side cross section of the new pavement, a row of positioning frames are welded on the pouring plate and a fixing plate at equal intervals, the two rows of positioning frames are oppositely supported and are combined in a staggered and inserted manner, and a positioning plate is inserted in the two rows of positioning frames in a penetrating manner; and two plugging positioning assemblies are installed on the positioning plate in a left-right corresponding sliding mode, and a top cover is connected to the strip-shaped base in a locking mode. The top cover can cover a gap between a new road surface and an old road surface to prevent the gap from being buried by gravels and dust, and the problems that a tensioning mechanism is blocked by the gravels and the dust, and the function is invalid are solved.

Description

technical field [0001] The invention relates to the technical field of splicing structures for highway engineering, in particular to a splicing structure for new and old roadbeds and pavements of highway engineering. Background technique [0002] With the modernization of our country, expressways are like blood vessels that closely connect all parts of the country together. In the process of expressway expansion, it is necessary to splicing the old and new road surfaces together through splicing structures, making full use of the old road surfaces, and saving The purpose of speeding up the construction speed of the project. [0003] The design of the splicing structure of the existing roadbed and pavement is not perfect, and most of them cannot use the rolling gravity of the vehicle to tighten and maintain the old and new pavement, resulting in the old and new pavement gradually loosening over a long period of time, and the splicing gap between them gradually expands, result...

Problems solved by technology

[0003] The design of the splicing structure of the existing roadbed and pavement is not perfect, and most of them cannot use the rolling gravity of the vehicle to tighten and maintain the old and new pavement, resulting in the old and new pavement gradually loosening over a long period of time, and the splicing gap between them gradually expands, resulting in the splicing structure. The new and old pavement is completely broken when it is pulled off, which affects the connection strength and durability of the old and new pavement
