Construction device and construction method of expressway roadbed

Abstract

A construction device for an expressway roadbed comprises a rack, a crushing mechanism, a rolling mechanism, a pressing plate mechanism and a water spraying mechanism, the crushing mechanism, the rolling mechanism, the pressing plate mechanism and the water spraying mechanism are fixedly installed on the rack, the crushing mechanism is installed at the front end of the rolling mechanism, the rolling mechanism is installed at the front end of the pressing plate mechanism, the water spraying mechanism is mounted above the rolling mechanism, the roadbed washed by rainwater is crushed through the crushing mechanism, then crushed roadbed soil is flattened through the rolling mechanism, and finally, the road surface is further leveled through the pressing plate mechanism, so that the roadbed leveling efficiency is conveniently improved; and meanwhile, dust in the crushing process is treated through the water spraying mechanism, and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of roadbed construction, and in particular relates to a construction device and a construction method for an expressway roadbed. Background technique [0002] The development of expressways affects the evolution of the spatial structure of urban agglomerations, attracting a large number of industries to choose locations along the line, build factories and bases; expand the scope of people's activities, promote the formation of satellite towns and economic and cultural exchanges between urban and rural areas, reduce traffic pressure, and adjust urban layout; Promoting industrial development drives the prosperity of the tertiary industry, increases employment opportunities and income, automobile consumption, and improves people's quality of life; improves the transportation structure, increases the port's distribution capacity, and diverts the pressure of railways, which is conducive to the formation of an inte...

AI Technical Summary

Problems solved by technology

[0003] The roadbed is one of the important basic components of the expressway. When the expressway is widened, the roadbed needs to be widened first. Most of the existing widening methods are to lay the roadbed earth and rocks on the ground by vehicles, level them mechanically, and finally use a road roller to repeatedly flatten them. Although this method is practical, after the roadbed soil and rocks are rained, the accumulated roadbed soil and rocks are easy to harden and it is difficult to flatten them directly. It requires a lot of manpower and material resources, and the work efficiency is not high. At the same time, a lot of dust will be generated, which will affect the environment.
