Embodiment Construction

[0022] The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0023] Such as figure 1 As shown, the method for controlling roadbed full-layer disease of the road bed provided by the invention as raw material comprises the steps:

[0024] (1) Carry out full layer density detection on the subgrade;

[0025] (2) Carry out the disease grade evaluation of each layer according to the compactness;

[0026] Among them, the disease level can be divided into slight porosity, moderate porosity, severe porosity and void according to the compactness standard of 0.8-0.9, 0.7-0.8, 0.6-0.7, and <0.6 respectively;

[0027] The evaluation and treatment of each layer can be carried out based on the above density range, and can also be further combined with the qualitative analysis of the multi...

Abstract

The invention relates to the technical field of disease management of road subgrades and relates to an all-level disease management method of the road subgrades. The all-level disease management method comprises the following steps: carrying out all-level compactness detection on the subgrade; carrying out disease grade evaluation of each level according to the compactness; preparing grouting slurry containing textile fibers according to disease grades; grouting by layers according to the disease grades. The invention provides a directional and layered grouting reinforcement technology and rapid and emergency treatment on subgrade diseases can be realized to ensure smooth urban traffic operation; the cost is saved and the recycling of wastes can be realized; the all-level disease management method has important practical significance and great social benefits in the aspects of maintaining society stability, saving energy, protecting environment and the like and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of road subgrade disease control, in particular to a method for treating road subgrade full-layer disease using textile fibers as raw materials. Background technique [0002] There are usually dense pipelines in the lower part of the municipal road. If the thickness of the roadbed structure layer is thin, or when the road section is on soft soil foundation, with the sharp increase of traffic load and traffic volume, this section of municipal road will be prone to accidents. The larger settlement eventually develops into subsidence disease, which greatly affects the service quality and safety performance of the road. However, the subgrade is in a closed state, coupled with the complex engineering geology and hydrogeology, once a disease occurs, it will become very difficult to deal with it. Considering the characteristics of tight construction time and small construction area, the restoration of traffic after...
