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 ...

This application relates to a new technology for highway slope protection, which includes the following steps: (1) opening a first installation hole on the slope of the unstable area, opening a second installation hole and a third installation hole on the slope of the stable area, and opening the second installation hole on the slope of the stable area. The installation hole corresponds to and communicates with the first installation hole; (2) A support assembly is provided between the stable area and the unstable area, and the support assembly includes piles arranged in the first installation hole and plugged into the second installation hole And the drill bit fixed to the end of the pile; (3) A cylindrical through hole is set on the pile, and a threaded rod is installed on the drill bit, and a reinforcement component connected with the slope of the stable area is arranged on the threaded rod; (4) The planting net is laid on the slope of the stable area, and the piles pass through the planting net and are fixed with it. In this application, the threaded rod in the pile is connected to the slope in the stable area through a reinforcement component, which enhances the stability of the pile during use, so that the pile can still play a good role in slope protection in areas with soft soil. Reduced chances of soil erosion.
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...
