Construction method for protecting existing building wall during tunnel excavation
The invention relates to a construction method for protecting an existing building wall during tunnel excavation, and relates to the technical field of existing building supporting, and the construction method comprises the following construction steps that reinforcing piles are arranged for the periphery of a starting well needing to be excavated; an isolation assembly capable of isolating the peripheral side wall of the starting well from the foundation is arranged between the reinforcing pile and the starting well; a supporting assembly is arranged on one side wall, symmetrical to a tunnel excavation opening, in the starting well, and the supporting assembly supports the wall body through the counter-force effect; reinforcing the ground in the starting well to form a ground reinforcing layer; and the reinforcing assembly is driven underground, and the reinforcing assembly is used for improving the stability of the ground in the starting well. The method has the effect of conveniently protecting the existing building according to the foundation settlement condition.
本申请涉及一种隧道开挖保护既有建筑墙体的施工方法，涉及既有建筑支护技术领域，其施工步骤如下：针对需要开挖始发井的周围进行加固桩的设置；加固桩与始发井之间设置能够对始发井的周侧壁与地基之间进行隔离的隔离组件；始发井内与隧道开挖口对称的一侧壁处设置支护组件，支护组件利用反力作用对墙体进行支撑；对始发井内的地面进行加固，形成地面加固层；在地面下进行加固组件的打入，加固组件用于提高始发井内的地面的稳定性。本申请具有便于根据地基沉降状况对既有建筑进行保护的效果。
