Raking group assembly for road construction vehicle

Technical Field

The utility model relates to an engineering machine tool technical field especially relates to a harrow group subassembly for road construction car.

Background

A road is generally composed of a road surface and a roadbed, and the road surface is a layered structure which is laid on the roadbed of the road and bears a load of vehicles. The pavement is composed of a surface layer, a base layer and a subbase layer. In the highway construction of our country, lime and cement are widely used for building highway subbase layers and base courses. The stabilized soil can generate cracks due to thermal shrinkage, is greatly influenced by the environment and can cause pollution to the environment in the construction process. With the enhancement of environmental awareness of people, the exploitation of stone, river sand, mountain sand and other resources used in road engineering is limited, and a novel soil curing agent of a curing material appears. The soil solidifying agent is a novel material which can be used for solidifying materials such as soil, sand and stones and the like. It has the advantages of convenient use, low cost, high curing speed and high strength after curing.

The soil solidifying construction method includes removing humus on the surface of soil, crushing the surface soil, spraying soil solidifying agent, compacting road surface and maintaining.
