Road construction pretreatment device and construction method thereof

Abstract

The invention discloses a road construction pretreatment device. The road construction pretreatment device comprises two rows of roadbed support bodies, an even number of support layers and a plurality of connecting plugs, wherein the two rows of roadbed support bodies are arranged inside a roadbed in the extending direction of the roadbed; the roadbed support bodies of any row of roadbed supportbodies are uniformly partitioned from one another, and any roadbed support body comprises a plurality of support pieces arranged in a tandem array manner; the even number of support layers extend in the length direction of the roadbed and are arranged inside the roadbed; the connecting plugs are embedded at the joint of two sections of the roadbed. According to the road construction pretreatment device provided by the invention, the strength, stability and drainage performance of the roadbed can be improved effectively, the traffic load capacity of the road is improved integrally, and the service life is prolonged. A correct and reliable construction method is further provided for the road construction pretreatment device.

Description

technical field [0001] The invention relates to the field of road subgrade construction, in particular to a road construction pretreatment device and a construction method thereof. Background technique [0002] At present, with the development of my country's highways, especially the rapid development of high-grade highways, the comfort and flatness of the road surface has been increasingly paid attention to by people. The subgrade is an important part of the road, and it is a belt-shaped structure built according to the route position and certain technical requirements. It should bear the load transmitted from the road surface and should have sufficient strength, stability and durability. The strength and stability of the roadbed are affected by objective factors such as water, temperature, and soil quality, as well as by traffic loads, human factors such as the correctness of roadbed design, construction methods, and maintenance methods. In view of the current improvement...

AI Technical Summary

Problems solved by technology

However, the actual improvement effect is not good, and the strength, stability and drainage performance of the roadbed are still not effectively improved, resulting in potholes and unevenness on the road surface, which reduces the comfort of vehicles and even causes dangers such as large-scale subsidence of the road surface.
