Shield launching and receiving reinforcing structure and method based on waterproof curtain
The invention relates to a shield launching and receiving reinforcing structure and method based on a waterproof curtain, and belongs to the field of rail transit construction. The leakage risk exists in existing shield launching and receiving reinforcement, and the construction cost can be increased due to reinforcement expansion. The invention provides a waterproof curtain-based shield launching and receiving reinforcing structure and method.The waterproof curtain-based shield launching and receiving reinforcing structure comprises a shield end well for shield launching or receiving, one end of the shield end well is connected with a shield tunnel, and a cement stirring wall is arranged at the position, on one side of the shield end well, of the shield tunnel to serve as a waterproof curtain; the cement stirring wall is formed by integrally connecting two outer enclosing walls surrounding the two sides of the shield tunnel and a middle wall corresponding to the excavation working face of the shield tunnel, continuous rows of stirring piles are arranged on the inner side of the waterproof curtain close to the shield end well to form a reinforcing body, and a reinforcing structure is arranged at the joint of the waterproof curtain and the shield end well. A plurality of dewatering wells are arranged on the inner side of the waterproof curtain and avoid the shield tunnel. The water stop effect can be improved, the leakage risk is reduced, the construction cost is low, and the construction period can be shortened.
本发明是一种基于止水帷幕的盾构始发接收加固结构及方法，属于轨道交通施工领域。现有盾构始发接收加固存在渗漏风险，加固扩大会使造价提升。本发明提供一种基于止水帷幕的盾构始发接收加固结构及方法，包括盾构始发或接收的盾构端头井，盾构端头井一端与盾构隧道相连，盾构端头井一侧的盾构隧道处设置水泥搅拌墙作为止水帷幕，所述水泥搅拌墙由围在盾构隧道两侧的两道外围墙和对应盾构隧道挖掘作业面的中间墙一体连接而成，止水帷幕的内侧紧邻盾构端头井设置连续成排的搅拌桩形成加固体，止水帷幕和盾构端头井的接缝处设置加固结构，止水帷幕的内侧避开盾构隧道设置若干降水井。本发明可提升止水效果降低渗漏风险，工程造价低、工期可缩短。
