Laying device for waterproof layer of collapsible loess road

Abstract

A collapsible loess road waterproof layer laying device, comprising: a waterproof membrane accommodating cavity, a ploughing mechanism, and a traction mechanism; wherein the waterproof membrane accommodating cavity rotates and fixes a waterproof membrane roll inside the waterproof membrane accommodating cavity, the bottom of the waterproof membrane accommodating cavity is pointed, and the waterproof membrane The accommodating cavity is used to be hammered into the ground under the action of external force, so that the middle and lower parts of the waterproof membrane roll are located underground; the soil ploughing mechanism is in the shape of a strip, and the soil ploughing mechanism is used to fix the end of the waterproof membrane roll and pull the end to extend along the road The ground breaking movement is used to spread the waterproof membrane roll longitudinally on both sides of the road. The traction mechanism is used to connect the plough mechanism and the traction machine to provide traction for the plough mechanism. The traction mechanism is also used to keep the plough mechanism in being pulled. gesture. The invention is a special laying waterproof membrane device for the aforementioned subgrade structure, which has the advantages of simple structure, firm construction, convenient construction and high efficiency, and solves the problem of laying the waterproof membrane of the new subgrade structure.

Description

[0001] Technical field: [0002] The invention relates to the technical field of road construction, in particular to a waterproof layer laying device for collapsible loess roads. [0003] Background technique: [0004] Collapsible loess is a special kind of rock and soil that has high strength and low compressibility in dry conditions, and its strength drops suddenly under a certain external force or under the action of its own weight when it meets water. The soil quality is relatively uniform, the structure is loose, and the pores are developed. During its formation, sufficient pressure and suitable humidity are often not available at the same time, resulting in poor compaction of the soil layer. The soil layer close to the surface of 2 to 3 meters is affected by the atmosphere. Due to the influence of precipitation, it generally has a suitable humidity for compaction, but at this time the weight of the overlying soil is very small, and the soil layer cannot be fully compacted...

AI Technical Summary

Problems solved by technology

For the treatment of collapsible loess foundations above level II, such as using soil or lime soil cushion, soil piles or lime soil piles, pile foundation pre-soaking method, and clay wrapping, there are various degrees of heavy workload, labor cost, and large construction site. Disadvantages such as long construction period and high cost
