Problems solved by technology

[0004] Due to the change of viscosity properties of steel fiber cement slurry, its grouting diffusion mechanism is very complicated, which brings great inconvenience to the selection of grouting parameters in the grouting process
Moreover, at present, steel fiber cement grout is mainly used in building foundation reinforcement, etc., and the patent document with ...

Embodiment Construction

[0034] In order to make the purpose, technical solution and effect of the present application more clear and definite, the present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0035] Please also refer to Figure 1-Figure 3 , the application provides a roadbed disease control method, comprising steps:

[0036] S10. Arranging grouting holes:

[0037] According to the scope of the diseased area, several grouting holes 1 are drilled in the diseased area, and the hole spacing of adjacent grouting holes 1 is the first distance threshold; Insert the grouting pipe 11 in each grouting hole 1 respectively, and Several grouting pressure sensors 12 are installed on the outer wall of each said grouting pipe 11;

[0038] S20, arranging drainage holes:

[0039] At t...

Abstract

The invention relates to the field of highway roadbed maintenance, in particular to a highway roadbed disease treatment method. The highway roadbed disease treatment method comprises the following steps of S10, arranging grouting holes; S20, arranging drainage holes; S30, grouting for blocking; and S40, grouting for compacting and reinforcing. According to the scheme, when being used, the highwayroadbed disease treatment method can achieve the following effects that 1) the grouting holes and the drainage holes are accurately arranged according to the extreme value theory and the effective radius of the single-hole diffusion, so that the accuracy of the diffusion range of slurry and the economization of the disease treatment cost are realized; 2) the diffusion range of the slurry for grouting and the end time of grouting can be precisely controlled, so that the situation that a large amount of slurry is wasted and the normal operation of a tunnel is affected due to the fact that the mud slurry flows out of a roadbed along a gap is avoided; and 3) the drainage function is utilized, so that the flushing force of a disease core area to the slurry is slowed down, and the range of the slurry diffusing along a drainage pipe is lager.

Description

technical field [0001] The application relates to the field of roadbed maintenance, in particular to a method for treating roadbed diseases. Background technique [0002] In recent years, a considerable number of roads will have problems such as pavement cracking, hollowing out, wrong platform and softening and settlement of roadbed (water inrush) soon after they are completed and opened to traffic. These diseases are "invisible killers" that cause road accidents, and pose a serious threat to people's lives and social security. [0003] Grouting is one of the main technical means for anti-seepage and reinforcement of underground engineering, and it has been widely used in water conservancy engineering, traffic engineering, tunnel engineering and mining engineering. In the water-rich and high-fill road subgrade area, due to the large water flow in the diseased area, the use of traditional cement slurry can no longer meet the design requirements. Due to the characteristics o...
