Saw cutting excavation method for hard rock stratum deep foundation pit close to ancient building group
The invention relates to the technical field of foundation pit construction, in particular to a saw cutting excavation method for a hard rock stratum deep foundation pit close to an ancient building group. Comprising the following steps that S1, leveling operation is conducted on an upper-layer site of the hard rock stratum deep foundation pit to be excavated; s2, surveying and lofting are conducted on the field where leveling operation is completed, and the boundary to be cut of hard rock stratum deep foundation pit construction is determined; s3, after the boundary to be cut is determined, cutting is conducted in the longitudinal direction of the boundary to be cut and the transverse direction perpendicular to the cutting boundary, and deep foundation pit excavation operation is conducted; s4, rock cut in the deep foundation pit excavation operation is hoisted and transported to the ground; and S5, circularly operating according to the step S3 and the step S4, and cutting rocks of the hard rock stratum layer by layer until the deep foundation pit is completely excavated. The method is safe and efficient, no influence is generated on buildings around the foundation pit, and the construction efficiency of the whole project is improved.
本发明涉及基坑施工技术领域，尤其涉及一种用于临近古建筑群硬岩地层深基坑锯切开挖方法。包括以下步骤：S1：对即将开挖的硬岩地层深基坑的上层场地进行平整作业；S2：对完成平整作业的场地进行测量放样，确定出硬岩地层深基坑施工的待切割边界；S3：确定待切割边界后，沿着待切割边界的纵向和垂直于切割边界横向进行切割，进行深基坑开挖作业；S4：将深基坑开挖作业中切割出的岩石吊装运输至地面；S5：按照步骤S3和S4循环作业，对硬岩地层的岩石进行逐层切割，直至深基坑开挖完成。该方法安全高效，不会对基坑周围的建筑物产生影响，并且提升了整个工程的施工效率。
