Description

Technical Field

[0001] The present invention belongs to the field of civil engineering technology, and specifically relates to a geotechnical reinforcement process and reinforcement device under urban geological environment. Background Technique

[0002] The rock and soil layer is a natural layer composed of rocks and soil, and its characteristics and distribution depend on various factors such as climate, topography, geological structure, and time. The formation of the rock and soil layer usually undergoes a long geological evolution process, with complexity and diversity. In engineering geological exploration, the research and analysis of the rock and soil layer are the basis for understanding the engineering geological conditions of the site. By exploring, sampling, testing, observing, and studying the composition, structure, physical properties, and mechanical properties of the rock and soil layer, its stability and bearing capacity can be evaluated, providing an important basis for engineering design and construction.

[0003] Rock and soil layer reinforcement is an important measure to ensure the stability and safety of buildings. The following are some common rock and soil layer reinforcement methods: Reinforcement grouting: Injecting slurry into the rock and soil mass to fill voids and increase the density and cohesion of the rock and soil mass. Common grouting materials include cement slurry and acrylate slurry, which are suitable for reinforcing rock masses or improving the strength and stability of sand slopes. Geogrid: A grid-like structure made of polymer materials, fixed to the ground or rock mass through structures such as anchor bolts, dug piles, and diaphragm walls. Geogrids can increase the shear strength and tensile strength of the rock and soil mass, improving its stability and bearing capacity. Anchoring technology: Connecting the building to the underground rock or soil through special devices to play a role in fixing and supporting. Anchoring technology can increase soil strength, reduce building displacement, and reduce the influence of external forces such as earthquakes and wind, thereby enhancing the stability of the building. In addition, it can also be used to repair and reinforce existing geotechnical structures and extend their service life.

[0004] A retaining wall is a building that prevents soil landslides or collapses and is widely used in civil engineering. The function of a retaining wall is to bear the soil pressure to maintain the stability of the soil mass and prevent natural disasters such as soil erosion and landslides. The structural forms of retaining walls are diverse, and different structural forms can be selected according to different topographic, geological, and environmental conditions, such as gravity type, cantilever type, counterfort type, and anchored type. The design of a retaining wall needs to consider various factors, such as the magnitude and direction of soil pressure, foundation bearing capacity, earthquake, and climate conditions. At the same time, the design of a retaining wall also needs to pay attention to its economy, environmental protection, and durability. During the construction process, the construction quality of the retaining wall is crucial for its stability and safety, and it is necessary to construct strictly in accordance with the design requirements and strengthen quality inspection and control. In short, the retaining wall is one of the important buildings in civil engineering and has important significance for protecting the natural environment and the safety of human life and property. In practical applications, it is necessary to select the appropriate type of retaining wall and construction method according to specific conditions to ensure its stability and safety.

[0005] Existing retaining walls are used to prevent landslides on the slopes of rock and soil layers. However, before constructing the retaining wall, it is difficult to ensure that the rock and soil layers will not cause landslides and damage to the soil structure due to construction and other reasons. The construction risk is relatively high. Moreover, during the subsequent construction process, it is found that it is difficult to quickly drain water from the rock and soil layers. A large amount of water is difficult to drain, which will lead to poor structural strength and is extremely easy to be damaged. During the process of forming and pouring the retaining wall using a mold, it is often difficult to achieve a stable retaining wall with different thicknesses. Moreover, during the pouring process, it is difficult to sprinkle water to cure the concrete, resulting in inconsistent structural strength of the retaining wall. Summary of the Invention
