Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of foundation anti-corrosion structures, in particular to a foundation anti-corrosion structure. Background Art
[0002] In the construction of highways and railways, the routes often pass through soft soil sections such as paddy fields and river ditches. The bearing capacity of the shallow soft soil layer in these sections often cannot meet the design requirements of the structure. Reasonable and economical methods must be used to reinforce the soft soil foundation. Soft soil is mainly silt and silty soil, which has the characteristics of low bearing capacity, high compressibility, high water content and low permeability coefficient. If it is not treated, it is difficult to use. The general methods for treating soft soil foundations include replacement method, sand (gravel) pile compaction method, heavy hammer tamping method, dynamic tamping method, rotary spraying method, etc. The replacement method has the disadvantage of high cost. The sand (gravel) pile compaction method requires the use of special steel pipes and equipment for pressing and pulling pipes, and the construction method is relatively complicated. For methods such as heavy hammer tamping method, dynamic tamping method, and rotary spraying method, large-scale special machinery and equipment are required for construction. However, small bridges and culverts in road network projects have small engineering quantities and require frequent transportation of machinery and equipment. Large-scale construction cannot be carried out, the cost is too high, and it is difficult to achieve the expected benefits. Traditional soft soil foundation treatment also uses pine piles made of pine wood. Pine piles are light and high-strength. Silt and silty soil have little horizontal resistance. The upper end of the pile is prone to overall horizontal displacement, which can tear ground facilities. Therefore, pine piles should not be used in areas where the groundwater level changes greatly. Bamboo is an important green resource with the advantages of light weight, high strength, good seismic performance, and short growth cycle. It is increasingly widely used in the construction industry, and raw bamboo is the most important bamboo species used in construction in my country. In modern bamboo structures, raw bamboo is used as load-bearing structural components such as columns and beams. Therefore, it is suitable for the soft soil foundation treatment of retaining walls with narrow channels.
[0003] The existing technology has the following problems:
[0004] After extensive searching, it was found that the Chinese patent publication number: CN212294605U discloses a raw bamboo grouting reinforcement soft soil foundation structure, which is characterized by comprising a soft soil foundation, raw bamboo, reinforcement material, pile tip, filling material, anticorrosive material and a cushion layer, the pile tip is installed at the bottom end of the raw bamboo to block the bottom end of the raw bamboo, 1 to 5 circles of reinforcement material are wrapped and reinforced on the upper end of the raw bamboo, the anticorrosive material is brushed and impregnated on the inner and outer surfaces of the raw bamboo, the raw bamboo is vertically installed to the inside of the soft soil foundation at discrete intervals, the filling material fills the cavity of the raw bamboo, and one or more of 100 to 400 mm thick stone, gravel, pebbles or sand is laid on the top of the grouting raw bamboo as a cushion layer. The patent is convenient to obtain materials, the materials are green and renewable, sustainable development, the construction method is simple and fast, the cost is low, and the raw bamboo grouting pile composite foundation comprehensively utilizes the role of the pile body, the role of the cushion layer and the compaction role.
[0005] However, the above patent still has certain shortcomings in actual use. The most obvious one is that in the process of driving the raw bamboo into the soft soil foundation, the wear resistance of the pile tip needs to be improved. In the process of driving the raw bamboo, the pile tip is easily damaged, which leads to the problem of damage caused by direct friction between the raw bamboo and the soft soil foundation. Secondly, the ability to resist acid and alkali erosion needs to be improved.
[0006] Therefore, it is necessary to provide a foundation anti-corrosion structure to solve the above technical problems. Utility Model Content
