Uneven pavement pretreatment device for highway widening construction

Abstract

The invention discloses an uneven pavement pretreatment device for highway widening construction in the technical field of highway construction. The device comprises a bearing assembly including a guide vertical plate, a movable frame assembly and processing assemblies, wherein a movable support is driven by an adjusting cylinder; the movable frame assembly includes a left frame and a right frame,and the left frame and the right frame are both notch type rectangular frames; and the processing assemblies are arranged on the platforms on the top surfaces of the left frame and the right frame respectively. The processing assemblies are moved to a height flush with the original roadbed ground through the movable support and the movable frame assembly, when the ground protrudes, a soil crushing disc works, crushed soil residues are sucked into an upper shell, when the ground sinks, trowelling operation is performed through a trowelling disc, and a different-direction rotating rod structureis synchronously driven to rotate; and residual branches of trees in protruding blocks are discharged to the two sides, the situation that the soil crushing disc is stuck is avoided, subsequent concrete pouring is smoother, working efficiency is improved, and labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an uneven road surface pretreatment device for road widening construction. Background technique [0002] Highway, literally means the road of public transportation. Roads are engineering facilities for various vehicles (trackless) and pedestrians. According to its use characteristics, it can be divided into urban roads, highways, factory and mine roads, forest roads and rural roads. In accordance with the relevant regulations and technical standards of highway management, highways are public roads between cities, between urban and rural areas, and in rural areas that can be driven by cars, which are built in accordance with the technical standards of highway engineering stipulated by the state and approved by the competent highway department. [0003] In order to reduce the traffic pressure of the road, the road is often widened and constructed. Before widening, the r...

AI Technical Summary

Problems solved by technology

[0003] In order to reduce the traffic pressure of the road, the road is often widened and constructed. Before widening, the road surface needs to be treated so that it can meet the standard of laying concrete. The road surface on both sides of the original roadbed has the following problems: 1. The problem of unevenness; 2. The problem of weeds or branches growing on the surface of the road surface; at present, it is processed manually without special processing equipment, which not only has low work efficiency, but also has poor processing effect. Therefore, we propose a road widening construction unevenness Pavement Pretreatment Device
