Embodiment 1

[0035] Subsidence occurred in a certain section of roadbed, see figure 1 (1);

[0036] The specific process of eliminating subgrade settlement by the inventive method comprises the following steps:

[0037] (1) Build the subgrade slope workbench, and the construction equipment is in place, and the construction equipment includes drilling equipment and grouting equipment, see figure 1 (2), the grouting equipment is not shown in the figure.

[0038] (2) According to the settlement position of the subgrade, use drilling equipment to carry out radial drilling on the side slope of the subgrade, see figure 1 (3), see after drilling figure 1 (4);

[0039] (3) Put the settlement compensation device in the hole, see figure 1 (5);

[0040] (4) Inject high-pressure cement slurry into the settlement compensation device through the grouting equipment, and the volume of the settlement compensation device will expand, generating surrounding pressure to act on the subgrade. Due to the l...

Embodiment 2

[0044] A section of subgrade has subsided within 10m of its full width, and the difference between the lowest subsidence and the road surface is 30cm;

[0045] The specific process of eliminating subgrade settlement by the inventive method comprises the following steps:

[0046] (1) Build the subgrade slope workbench, and put the construction equipment in place, and the construction equipment includes drilling equipment and grouting equipment.

[0047] (2) According to the settlement position of the subgrade, use drilling equipment to carry out radial drilling on the side slope of the subgrade. The depth of the hole is greater than the width of the corresponding road surface. In order to facilitate the construction, the hole can be opened, see Figure 4 (b), the diameter of the hole is determined according to the descending depth of the position of the road section;

[0048] (3) Put a settlement compensation device in the hole. The specific settlement compensation device, tha...

Embodiment 3

[0052] Partial width subsidence occurs within a certain length range in a certain section of subgrade;

[0053] The specific process of eliminating subgrade settlement by the inventive method comprises the following steps:

[0054] (1) Build the subgrade slope workbench, and put the construction equipment in place, and the construction equipment includes drilling equipment and grouting equipment.

[0055] (2) According to the settlement position of the subgrade, use drilling equipment to carry out radial drilling on the side slope of the subgrade, and the depth of the hole can only be drilled to the boundary of the subsidence area, see Figure 5 (b), the diameter of the hole is determined according to the descending depth of the position of the road section;

[0056] (3) Put a settlement compensation device in the hole. The specific settlement compensation device, that is, the diameter of the airbag 1, is determined according to the descending depth of the position of the roa...

Abstract

The invention belongs to the technical field of road construction, and particularly relates to a roadbed settlement treatment method. The method specifically comprises the steps of (1) building a roadbed slope workbench, and putting construction equipment in place, wherein the construction equipment comprise drilling equipment and grouting equipment; (2) conducting radial drilling on the roadbed slope through the drilling equipment according to the roadbed settlement position; (3) putting a settlement compensation device into the hole; and (4) injecting high-pressure grout into the settlementcompensation device through the grouting equipment, wherein the volume of the settlement compensation device is expanded, the settlement part is jacked up, settlement compensation is completed after the high-pressure grout is solidified, and roadbed settlement is eliminated. The core of the method is punching, device placement, grouting expansion and extrusion lifting. The method is a brand-new technology, the traditional concept of mainly reinforcing is changed, the concept of compensating settlement to offset settlement is proposed for the first time, and meanwhile, a brand-new airbag deviceis adopted for construction and is proposed for the first time in related fields.

Description

technical field [0001] The invention belongs to the technical field of road construction, and in particular relates to a roadbed settlement treatment method. Background technique [0002] In the process of road construction, preventing uneven settlement of roads is a very important task in engineering construction management. Smooth roads are an important guarantee for driving comfort and safety. In recent years, the progress of road and other infrastructure construction in my country has been accelerating, and the design and construction level of road and other infrastructure has been continuously improved. In order to ensure the comfort and safety of road driving, the majority of engineering units have adopted methods such as reinforcing the foundation, adopting filling materials with good performance and quality, and optimizing the filling process, which have achieved certain results in preventing uneven settlement of the road. The problem of settlement has not been comp...
