Reverse construction method for slightly weathered rock area
The invention provides a reverse construction method for a slightly weathered rock area. The method includes the steps that the position of a basement outer wall is determined, and a vibration isolation trench is excavated along the basement outer wall; rock in the basement range is excavated to the ditch bottom of the vibration isolation ditch; the first step and the second step are repeated until the rocks in the basement range are lowered to a designed elevation of a basement roof; basement roof construction is conducted; the step one to the step four are repeated, and the horizontal structure of a basement is constructed downwards layer by layer until the construction of a bottom plate of the basement is completed; waterproof layer construction of the basement outer wall is conducted on a rock wall; and basement exterior wall construction is conducted from bottom to top through a single-side formwork erecting process. According to the reverse construction method for the slightly weathered rock area, a complete rock mass between the exterior of the basement and a supporting structure is reserved to serve as a force transmission system between the basement structure and the supporting structure in the reverse construction process, so that the excavation volume of the foundation pit rock is reduced, disturbance to the supporting structure and the surrounding environment is reduced, and outdoor backfilling is not needed.
本发明提供了一种微风化岩区的逆作施工方法，包括：确定地下室外墙的位置并沿地下室外墙开挖隔振沟；将地下室范围内的岩石开挖至隔振沟的沟底；重复步骤一和步骤二，直至地下室范围内的岩石降至地下室顶板设计标高；进行地下室顶板施工；重复步骤一至步骤四，逐层往下进行地下室水平结构施工,直至完成地下室底板施工；在岩壁上进行地下室外墙的防水层施工；采用单边支模工艺自下而上进行地下室外墙施工。在本申请提供的微风化岩区的逆作施工方法中，通过保留地下室外与支护结构之间的完整岩体，作为逆作施工过程中地下室结构与支护结构之间的传力体系，由此减少基坑岩石的开挖量，并降低对支护结构及周围环境的扰动，而且无需进行室外回填。
