Collapsible loess roadbed treatment device and using method thereof

Abstract

The invention relates to the field of road construction and particularly relates to a collapsible loess roadbed treatment device and a using method thereof. The device comprises a main body frame, and a land pricking wheel, a supporting wheel and a compacting wheel which are sequentially and fixedly installed on the main body frame from front to back, wherein sharp teeth are evenly distributed on the land pricking wheel, an adjusting mechanism is arranged on the supporting wheel, a square supporting frame is further fixed to the upper portion of the main body frame, and three feeding bins are evenly arranged in the middle of the supporting frame; vibrating hoppers are arranged below the feeding bins, the bottoms of the three feeding bins communicate with the vibrating hoppers through pipelines, vibrating rods are installed in the vibrating hoppers, strip-shaped grooves are formed in the bottoms of the vibrating hoppers and communicate with the outside, strip-shaped grooves are further formed in the positions of the strip-shaped grooves, a screen plate is arranged below the vibrating hoppers, and through holes are evenly formed in the screen plate; materials can pass through and fall to the ground. The device is ingenious in design, reasonable in structure, capable of fundamentally eliminating collapsibility of loess, capable of meeting the requirements for pavement structure and roadbed strength and suitable for wide application and popularization.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a collapsible loess subgrade treatment device and an application method thereof. Background technique [0002] During the construction of urban roads, the problem of collapsible loess subgrades is often encountered. At present, the traditional methods for dealing with municipal roads are mainly cushion method, compaction method, compaction pile method, and pre-soaked water method. The above technologies are not only limited by the conditions Restrictions, many of them cannot be used, and it also involves slow construction progress, complex construction technology and long time, which has caused a lag in the progress of the project. Using the above methods also increases the cost and does not achieve the expected effect, resulting in rework. The phenomenon. [0003] Therefore, it is necessary to solve the above technical problems. Contents of the invention [0004] In view of ...
