Description

Pine pile retaining wall structure for river bank protection Technical Field The application relates to the technical field of river revetment piles, in particular to a pine pile retaining wall structure for river revetment. Background In the current water conservancy and ecological environment construction field, comprehensive improvement of river channels is of great concern. The river course not only carries basic water conservancy functions such as flood discharge, drainage, irrigation and the like, but also is a key vein of an ecological system, and plays a role in maintaining biological diversity and shaping aesthetic value of landscapes. The river bank protection is used as a guard for the stable operation of a river system, and the structural form and the performance quality of the river bank protection are directly related to the long-term security of the river and the healthy development of the surrounding ecology. The traditional retaining wall for the riverway revetment pine piles usually takes pine piles as core supporting elements, and the pine piles are driven into bearing layers below a riverbed one by one according to a specific interval, and the arrangement mode of the retaining wall is mostly compact arrangement or quincuncial distribution. With respect to the related art, the inventor believes that the water flow can generate significant lateral thrust on the pine pile retaining wall, and the anchoring connection between the pine pile and the riverbed soil body is relatively weak, so that the pine pile is difficult to stably fix by simply relying on the friction force of the pile body soil-entering part. Disclosure of utility model The application aims to provide a pine pile retaining wall structure for river bank protection, which aims to solve the problem that the lateral thrust of a pine pile retaining wall is difficult to stably fix due to water flow by simply relying on the friction force of a pile body in a soil part between a pine pile and a river bed soil body. The application provides a pine pile retaining wall structure for river bank protection, which adopts the following technical scheme: A pine pile retaining wall structure for river bank protection comprises a river glacis and is characterized in that a fixing groove is formed in one side, close to the river, of the river glacis, a pouring bearing layer is arranged in the fixing groove, a plurality of pine piles arranged in the vertical direction are arranged on the pouring bearing layer along the length direction of the river glacis, a plurality of fixing ribs are arranged on the pouring bearing layer along the vertical direction, corresponding to the pine piles, and the fixing ribs penetrate through the pine piles. By adopting the technical scheme, the connection relation between the pine pile and the river bed soil body is enhanced by the arrangement of the fixing ribs, when lateral thrust is generated by water flow, the pine pile can transmit force to the pouring bearing layer by means of the fixing ribs, the pouring layer bearing layer tightly fills the fixing groove to form a continuous and firm stressed whole with the river bed soil body, and when the lateral thrust is generated by water flow impact, the pouring bearing layer can disperse force to the river bed, so that the bearing stability of a foundation is ensured, and the collapse risk is reduced. Optionally, the adjacent pine piles are laminated and arranged. Through adopting above-mentioned technical scheme, many pine piles are closely combined, form the structure of similar continuous wall body, and whole cooperation resists the ability promotion of rivers impact, evenly distributes the power to adjacent stake on, reduces because of the uneven problem such as stake slope, rupture that causes of local atress to reduce the maintenance frequency, save long-term maintenance cost. Optionally, slots are arranged along the up-down direction on the adjacent pine piles, and inserting plates are inserted into the slots. By adopting the technical scheme, the connection between adjacent wood piles is strengthened, the relative displacement between the wood piles is further limited, the wood piles can be better stressed cooperatively under the impact of water flow, the stress concentration points are reduced, the risk of structural damage caused by overlarge local stress is reduced, and the integrality of the retaining wall is ensured. Optionally, the slot penetrates through a part of the pine pile higher than the casting bearing layer, and the plugboard is matched with the slot. By adopting the technical scheme, the stress deformation of each part of the wood pile can be coordinated better, so that the whole pine pile is kept balanced and stable under the impact of water flow, and the long-term stability of the retaining wall structure is ensured. Optionally, the slot gradually becomes larger from bottom to top. Through adopting above-mentioned technical scheme, operatin
