Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to an assembled slope protection structure and a construction method thereof. Background Art

[0002] In terms of landslide prevention and control in my country, prevention is the main approach, with prevention being more important than treatment. Treatment emphasizes the unified consideration of various factors affecting slope stability, and the prevention and control of landslides is carried out in a prioritized, prioritized, and selective manner according to the role of each factor. At present, the main landslide prevention and control measures are to avoid, improve the drainage system, resist sliding support, and improve the sliding belt soil. In order to meet the purpose of treatment, these prevention and control measures are generally used in combination in landslide prevention and control. For the protection of artificial slopes, plants are often used at the same time to prevent topsoil erosion, consolidate slopes, and beautify the environment. In general, landslide protection technologies can be mainly divided into the following three categories.

[0003] 1. Engineering protection

[0004] Engineering protection includes drainage measures (setting up drainage ditches, etc.), slope protection measures (skeleton slope protection, stone slope protection, flexible protection, etc.), anti-slip support measures (local load reduction, retaining walls, soil nails, anti-slip piles, frame-anchor structures, etc.) and soil improvement measures (grouting reinforcement, etc.).

[0005] 2. Plant protection

[0006] Plant protection is to protect the slope from atmospheric precipitation and surface runoff by using the covering effect of vegetation and the reinforcement effect of plant roots, so as to achieve the effect of strengthening the slope and protecting the ecology. Plant protection has limitations, that is, it can only prevent slope erosion and surface soil collapse. In the case of unstable slope or concentrated water flow, slope collapse and water damage may still occur. Therefore, plant protection must be used on the basis of slope stability, or combined with engineering protection technology.

[0007] 3. Comprehensive protection

[0008] Comprehensive protection is a measure that uses plants, engineering and other applicable measures according to local conditions to control slope problems such as landslides and water damage. Summary of the invention

[0014] The connection node includes a prefabricated foundation, a prefabricated tension beam, reserved steel bars, a grouting reserved node, and reserved anchor holes.

[0015] After the reserved foundation is installed, the anchor slope is connected through the reserved anchor holes, and the reserved steel bars on the prefabricated tension beam are extended into the reserved grouting connection node area of ​​the prefabricated foundation to connect the nodes by grouting.

[0016] As a preferred solution of the assembled slope protection structure described in the present invention, the prefabricated foundation and the prefabricated tension beam can be constructed in a standardized manner, which can greatly shorten the construction period and improve the construction quality.
