Sectional hoisting method for reinforcement cage of ultra-low clearance underground diaphragm wall under high-voltage line
The invention discloses a segmental hoisting method for an ultra-low clearance underground diaphragm wall reinforcement cage under a high-voltage line, which comprises the following steps of: 1, establishing a simulation model for an area under the high-voltage line, carrying out clear height analysis, and solving the segmental length of the reinforcement cage; step 2, working condition constraint deduction: carrying out simulation verification on theoretical calculation in the step 1; and 3, carrying out field test outside the high-pressure corridor area according to the reinforcement cage sectional test hoisting scheme, and verifying the accuracy of the theoretical calculation in the step 1 and the deduction result in the step 2. The invention relates to the technical field of foundation pit engineering, and can solve the problem of high construction difficulty of an ultra-low clearance underground diaphragm wall reinforcement cage under a high-voltage line in the prior art.
本发明公开了一种高压线下超低净空地下连续墙钢筋笼分节吊装方法，包括以下步骤：步骤1：对高压线下区域建立仿真模型，进行净高分析，求解钢筋笼的分节长度；步骤2：工况约束推演，对步骤1中的理论计算进行模拟验证；步骤3：根据钢筋笼分节试吊方案在高压走廊区域外进行现场试验，验证步骤1中理论计算和步骤2中推演结果的准确性。本发明涉及基坑工程技术领域，能够解决现有技术中高压线下超低净空地下连续墙钢筋笼施工难度大的问题。
