Construction method and construction equipment for accurately excavating rock foundation pit through impact splitting
The invention discloses a construction method and construction equipment for accurately excavating a rock foundation pit through impact splitting. The construction method specifically comprises the following steps that S1, the range of the foundation pit is delimited; the edge of the foundation pit is marked according to a design line, a plurality of annular excavation lines are divided from the center of the foundation pit to the edge of the foundation pit within the range of the foundation pit, the interval between every two adjacent excavation lines is a construction width L2, constructors mark drilling positions along the excavation lines, the interval between every two adjacent drilling holes is L1, and finally the thickness D of a soil layer of the foundation pit excavated every time is determined; s2, a foundation pit is excavated; according to the construction method, drilling is conducted at the drilling position marked on the excavation line, then a splitting machine is inserted into the drilling hole, splitting construction is conducted on the drilling hole along the excavation line, the foundation pit excavation precision is improved, the conditions of over-excavation and under-excavation are prevented, and then the foundation pit excavation efficiency is improved in cooperation with the device.
一种冲击劈裂精准开挖岩质基坑的施工方法及施工设备，具体包括如下步骤：S1、划定基坑范围；按照设计线对基坑边沿进行标记，在基坑范围内从基坑中心到基坑边沿划分多个环形的开挖线，相邻开挖线间隔为一个施工宽度L2，施工人员沿开挖线对钻孔位置进行标记，钻孔的间隔为L1，最后确定每次开挖的基坑土层厚度D；S2、对基坑进行开挖；先标记在开挖线上的钻孔位置钻孔，然后在钻孔内插入劈裂机，沿开挖线对钻孔进行劈裂施工，本发明施工方法提高了基坑开挖的精度，防止超挖、欠挖的情况出现，再配合本发明的装置提高了基坑开挖的效率。
