Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the piles are arranged inside the slope to protect the soil where no landslide occurs. This type of design has high requirements for the soil quality of the slope. When the soil quality of the slope When it is soft, the stability of the pile is poor, and it is difficult to play a good slope protection function

Embodiment Construction

[0038] The following is attached Figure 1-6 The application is described in further detail.

[0039] The embodiment of the application discloses a new technique for slope protection of expressways. refer to Figure 1-2 , the new technology of this expressway slope protection comprises the steps:

[0040] (1) Open the first installation hole 11 on the slope of the unstable area 1, open the second installation hole 21 and the third installation hole 22 on the slope of the stable area 2, the second installation hole 21 and the third installation The holes 22 are sequentially arranged along the slope of the stable area 2 on the side away from the unstable area 1, and the second installation hole 21 corresponds to and communicates with the first installation hole 11;

[0041] (2) The support assembly 3 is jointly arranged on the stable area 2 and the unstable area 1, and the support assembly 3 includes a pile 31 that penetrates through the first installation hole 11 and an end ...

Abstract

The invention relates to a novel process for highway slope protection. The process comprises the following steps of (1) forming a first mounting hole in an unstable area slope surface, forming a second mounting hole and a third mounting hole in a stable area slope surface, and enabling the second mounting hole to correspond to and communicate with the first mounting hole; (2) arranging a supporting assembly between a stable area and a non-stable area, wherein the supporting assembly comprises a pile column arranged in the first mounting hole and connected with the second mounting hole in an inserted manner and a drill bit fixed to the end of the pile column; (3) forming a columnar through hole in the pile column, rotatably mounting a threaded rod on the drill bit, and arranging a reinforcing assembly connected with the stable area slope surface on the threaded rod; and (4) laying a planting net on the unstable area slope surface, wherein the pile column penetrates through the plantingnet and is fixed with the planting net. In the application, the threaded rod in the pile column is connected with the stable area slope surface through the reinforcing assembly, so that the stabilityof the pile column in the using process is enhanced, the pile column can still play a good slope protection role in areas with soft soil, and the probability of water and soil loss is reduced.

Description

technical field [0001] The application relates to the technical field of slope protection, in particular to a new technology for slope protection of expressways. Background technique [0002] When the slope formed in the engineering construction encounters rainy days or strong vibrations, geological disasters such as landslides, collapses, swelling or spalling often occur. In order to prevent the occurrence of the above-mentioned geological disasters, slope treatment is required. Among them, Anti-slide piles or prestressed cables, or the combination of anti-sliding properties and prestressed cables, are commonly used support structures for slope treatment. According to the geological composition, the slope can be divided into landslide body and sliding bed from outside to inside. The landslide body is also called the unstable area. Relatively, the sliding bed is called the stable area. Anti-slide piles or prestressed cables pass through The landslide body goes deep into the...
