Water conservancy project retaining wall and construction method thereof

WANG XIN'AN / ZHENG CHUNHAI

The invention relates to a water conservancy project retaining wall and a construction method thereof, and aims to solve the technical problem that the connecting strength of retaining wall units becomes low due to the fact that asphalt filling in a vertical expansion joint of a retaining wall is not compact. The water conservancy project retaining wall comprises a foundation layer, a soil layer, prefabricated retaining wall unit blocks, assembling blocks, an occlusion mechanism and an auxiliary baffle; a foundation layer; a soil layer is arranged on one side of the foundation layer, prefabricated retaining wall unit blocks are arranged on the foundation layer and connected with the soil layer, a gap between every two adjacent prefabricated retaining wall unit blocks forms an installation cavity, an assembly block is arranged in the installation cavity, and a meshing mechanism is arranged on one side of the assembly block and connected with the installation cavity. According to the prefabricated retaining wall unit block, the asphalt filling material is extruded through expansion of the meshing mechanism, so that the asphalt filling material is rapidly and uniformly distributed and filled in the filling cavity, the filling cavity is relatively uniformly filled with the asphalt filling material, and the firmness of connection of every two adjacent prefabricated retaining wall unit blocks is improved.

本发明涉及一种水利工程挡土墙及其施工方法，旨在对于挡土墙竖向伸缩缝中沥青填充不紧实的技术问题，导致挡土墙单元连接强度变低的技术问题，包括地基层、土层、预制挡土墙单元块、装配块、咬合机构及辅助挡板；地基层；土层布置于所述地基层一侧，预制挡土墙单元块布置于所述地基层上连接所述土层，其中，两个相邻所述预制挡土墙单元块间隙构成安装腔，装配块布置于所述安装腔内部，咬合机构布置于所述装配块一侧连接所述安装腔上。本发明通过咬合机构膨胀来对挤压沥青填充料产生挤压，使得沥青填充料迅速在填充腔内均布填充，致使填充腔内相对均匀填充有沥青填料，提高相邻两个预制挡土墙单元块连接的牢固性。
