Problems solved by technology

[0006] The above-mentioned patents only partially reinforce the subgrade. The tooth wall and solidified plate body formed by reinforcement can form lateral constraints on the soft soil, preventing water and soft soil from coming out of the edge of the plate body to cause road settlement. The reinforcement is only partial. For Due to incomplete reinforcement, the heavy-duty roadbed will hardly be damaged under the repeated action of heavy vehicles; in addition, there is no experiment on the selection of curing agent, which is applicable to some areas, but not necessarily applicable to other areas

Embodiment Construction

[0033] The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0034] A new road project is planned to pass through the saturated soft soil area. In order to ensure the stability of the road, according to conventional methods, it is necessary to replace the foundation soil within the subgrade area or carry out foundation reinforcement in other ways. Conventional replacement methods, excavation and transportation of earthwork The amount of filling and filling is very huge, and it is time-consuming. In order to reduce the amount of excavation and filling of earthwork, we adopt a method for in-situ reinforcement of roadbed under the geological condition of sat...

Abstract

The invention provides a method for strengthening a roadbed in place under a saturation soft soil geological condition. In the case of determining the position of the roadbed, the composition of softsoil is made clear; according to the composition of the soft soil, a special soft soil curing agent is prepared; the curing agent is blended into the soft soil; and then the soft soil is enabled to stand to change the physical and mechanical property of a roadbed soft soil layer; and therefore, the roadbed soft soil layer satisfies requirements on the road roadbed.

Description

technical field [0001] The invention belongs to the field of traffic construction engineering, and in particular relates to an in-situ roadbed reinforcement method under saturated soft soil geological conditions. Background technique [0002] At present, road engineering, especially temporary roads at the construction site, especially under the geological conditions of saturated soft soil, because the water content of the soft soil has reached saturation, it is very difficult to solidify the soft soil, and it cannot be reinforced in place at one time. At present, it is very common practice to replace construction waste and pour concrete pavement after compaction for temporary road subgrades on construction sites. This method is very costly for large-area soft soil foundation construction sites; many consider cost issues and do not go through replacement and compaction at all. , pour concrete pavement directly on the soft soil foundation, but the pouring thickness is slightly...
