Round-end-shaped pipe jacking well capable of being applied to complex environment and construction method of round-end-shaped pipe jacking well
The invention discloses a round-end-shaped pipe jacking well capable of being applied to a complex environment and a construction method of the round-end-shaped pipe jacking well. The horizontal section of the pipe-jacking well is in a round end shape, the two ends of the pipe-jacking well are semicircular, and the middles of the pipe-jacking well are connected linearly. A waterproof curtain is arranged on the periphery of the pipe jacking well, and internally-inserted section steel is vertically arranged in the waterproof curtain. A reinforced concrete well body is arranged on the inner side of the waterproof curtain and comprises an inverted-L-shaped well ring arranged on the top and a vertical well wall below the inverted-L-shaped well ring, and a sealing bottom is arranged at the bottom of the pipe jacking well and connected with the vertical well wall. According to the pipe-jacking well and the construction method thereof, it can be guaranteed that the structure of the pipe-jacking well has good stress performance, and the occupied area width can be saved; compared with a traditional reverse well, the reverse well is more suitable for environments with high underground water level, complex geological conditions (such as sand layers and mucky soil layers) and high peripheral deformation control requirements, the pouring frequency can be reduced, and the construction period can be shortened.
本发明公开了一种可应用于复杂环境的圆端形顶管井及其施工方法。所述顶管井的水平截面为圆端形，其两端各为半圆体形状，中间为直线相连；所述顶管井外围为止水帷幕，所述止水帷幕内竖向设置有内插型钢；止水帷幕内侧为钢筋混凝土井体，包括顶部设置的倒L型井圈和其下的竖向井壁，所述顶管井的底部有封底连接竖向井壁。本发明的顶管井及其施工方法既可保证其结构具有较好的受力性能，又可节约占地宽度；相比传统逆作井更加适用于高地下水位、地质条件复杂(如含有砂层、淤泥质土层等)以及周边变形控制要求较高的环境，并可减少浇筑次数、节约工期。
