Matched protection method for adjacent high-voltage electric tower in tunnel construction
The invention discloses a matching protection method for adjacent high-voltage electric towers in tunnel construction, which comprises the following steps: S1, segmental hoisting of a reinforcement cage: the reinforcement cage of a tunnel support pile is divided into a plurality of segments to be respectively hoisted, the first segment of the reinforcement cage is fixed by channel steel, and the subsequent reinforcement cage is respectively connected with the previous segment of the reinforcement cage by electric arc welding; s2, sleeve valve pipe deep hole grouting is conducted, specifically, multiple rows of deep drill holes are formed between the tunnel structure and the electric tower, and disturbance and differential settlement of the pile foundation structure of the electric tower are reduced in a sleeve valve pipe grouting reinforcement mode; s3, protecting the connecting beams of the pile foundations of the electric tower, and connecting all the pile foundations by newly building the connecting beams on the pile foundations of the electric tower, so that the stress of the whole electric tower is enhanced, and the structure of the electric tower is prevented from being disturbed; according to the method, cost can be saved, construction is convenient and safe, the construction speed of the next stage can be effectively increased, the problems that a traditional high-voltage electric tower migration method is long in construction period, large in risk, wide in influence and the like are solved, and meanwhile a safe and efficient construction environment is created for adjacent tunnel construction.
本发明公开了一种隧道施工临近高压电塔配套保护方法，包括：步骤S1、钢筋笼分段吊装，将隧道支护桩钢筋笼分为数段分别进行吊装，第一段钢筋笼采用槽钢固定，后续钢筋笼采用电弧焊接分别与前一段钢筋笼连接；步骤S2、袖阀管深孔注浆，在隧道结构与电塔间设置多排深钻孔，通过袖阀管注浆加固的方式减小电塔桩基结构扰动和不均匀沉降；步骤S3、电塔桩基连系梁保护，通过在电塔桩基上新建连系梁将所有桩基连成，加强电塔整体的受力，防止电塔结构受到扰动；本发明可以节约成本，且施工便捷、安全，可有效提高下一阶段施工速度，解决传统迁移高压电塔方法工期长、风险大，影响广等多种弊端的问题，同时为临近隧道施工创造既安全又高效的施工环境。
