Rock stratum foundation pit excavation method capable of preventing vibration energy from overflowing
The invention provides a rock stratum foundation pit excavation method capable of preventing vibration energy from overflowing. The rock stratum foundation pit excavation method comprises the steps that A, a foundation pit support structure is installed; b1, establishing a construction control network and elevation control points; b2, rock stratum excavation; b3, leveling treatment is conducted on the bottom face of the foundation pit, and a final excavation face is formed; in the step B2, construction is conducted in a layer-by-layer rock stratum excavation mode, and the specific process of excavation of each rock stratum comprises the steps that S1, leveling treatment is conducted on the upper surface of the rock stratum to form a track mounting face; s2, a rotary saw walking track is laid on the track mounting face; s3, the edge of the rock stratum is vertically cut; s4, the edge of the rock stratum is horizontally cut, and a seismic isolation groove is defined between the cutting face and the foundation pit support structure; s5, building an anti-seismic structure; and S6, the part, located in the space defined by the seismic isolation groove, of the rock stratum is exploded. The method has the advantage of small interference on surrounding buildings during construction, and is used for solving the problem that the surrounding buildings are greatly influenced by a rock stratum foundation pit in an explosion mode.
本发明提供了一种一种防振动能量外溢的岩层基坑开挖方法，包括A、基坑围护结构安装；B1、建立施工控制网、高程控制点；B2、岩层挖除；B3、对基坑底面进行找平处理，形成最终开挖面；B2步中通过逐层挖除岩层的方式进行施工，挖除每一层岩层的具体过程为：S1、对岩层的上表面进行找平处理形成轨道安装面；S2、将盘锯行走轨道铺设在轨道安装面上；S3：对岩层边缘进行垂直切割；S4：对岩层边缘进行水平切割，切割面和基坑围护结构之间围成隔震槽；S5：建筑防震结构；S6：对岩层位于隔震槽围成的空间内的部分剩进行爆破。本发明具有施工时对周边建筑干扰小的优点，用于解决岩层基坑通过爆炸的方式对周边建筑影响大的问题。
