Hard rock foundation pit construction method combining static crushing and mechanical chiseling
The invention relates to the technical field of constructional engineering, and discloses a static crushing and mechanical chiseling combined hard rock foundation pit construction method which comprises the following steps: S1, deepening a hard rock foundation pit into a stepped process by combining a rock crushing technical scheme design; s2, surveying and setting out; s3, static crushing parameters are designed based on a crack propagation rule, and then drilling and free surface construction are conducted; s4, static crushing agent slurry is poured into the drill holes; s5, secondary chiseling and crushing through a mechanical vibration method, wherein the efficiency of mechanical chiseling and crushing of the hard rock is improved by applying the vibration effect in the crack propagation direction; and S6, filling and carrying broken stones, wherein the broken stones are filled and transported to a spoil field. According to the construction method provided by the invention, a static crushing technology and a mechanical shock vibration chiseling technology are combined, the problems of convenient and flexible construction and weakening of the excavation difficulty of the hard rock foundation pit are solved at the same time, and the construction progress and the overall economic benefit of a project are improved on the basis of guaranteeing safe and civilized construction.
本发明涉及建筑工程技术领域，公开了一种静态破碎与机械凿除结合的硬岩基坑施工方法，其包括下列步骤：S1：联合破岩技术方案设计，将硬岩基坑深化为阶梯式工序；S2：测量放线；S3：基于裂纹扩展规律设计静态破碎参数，随后钻孔及自由面施工；S4：在钻孔内灌注静态破碎剂浆体；S5：机械振动法二次凿除破碎，通过对裂纹扩展方向施加振动效应提升机械凿除破碎硬岩的效率；S6：装填搬运碎石，将碎石块装填并运输到弃土场。本发明提供的施工方法将静态破碎技术与机械冲击振动凿除技术相结合，兼顾解决施工的方便灵活和削弱硬岩基坑的开挖难度的问题，在保障安全文明施工的基础上还提升了施工进度和项目整体的经济效益。
