Tunnel leakage water 3D printing repair construction method

By using 3D printing technology to construct a directional water-guiding system at the site of tunnel leakage, the problem of water leakage in cast-in-place reinforced concrete tunnels has been solved. This has enabled efficient repair without grouting and with minimal disturbance, thereby improving the durability and safety of the tunnel structure.

Abstract

本申请涉及渗漏水修复技术领域，特别涉及一种隧道渗漏水3D打印修复施工方法，包括：步骤S1：定位隧道渗漏水点、探测渗漏水点对应的渗漏通道；步骤S2：设计导水槽的导水路径；导水路径与渗漏水点对应的渗漏通道相交至少第一长度，并导向隧道底部排水沟；步骤S3：沿导水路径开凿导水槽、布置导水盲管；步骤S4：将T型止水带沿导水盲管走向扣设在导水盲管上；T型止水带的水平端预留卡槽，用于连接导水盲管；步骤S5：沿导水路径对导水槽进行3D打印施工。本申请摒弃高压注浆工艺，通过渗漏水点定位与通道的精准探测，以交叉导流的方式设计导水路径，结合导水槽、导水盲管及T型止水带构建定向导水体系，有效疏导地下水、降低水压力。
