Pile foundation pore-forming construction method for constructional engineering
The invention provides a construction engineering pile foundation pore-forming construction method which specifically comprises the following steps: S1, measuring and positioning: adopting a total station to carry out survey lofting on pile positions according to a design drawing, S2, carrying out one-pile one-exploration: adopting an engineering geological drilling rig to carry out advanced drilling on the geological condition of each engineering pile position, drawing a geological histogram, and carrying out one-pile one-exploration; and finding out an underground karst cave distribution range and a stratum structure. And S3, judging a hole forming mode: according to a one-pile one-probe result, analyzing the distribution positions of the karst caves, whether fillers exist in the karst caves or not, the states of the fillers, whether water leaks in the karst caves or not and other conditions, and determining the hole forming mode and matched construction mechanical equipment. The construction engineering pile foundation pore-forming construction method is high in innovative technological method pertinence, a one-pile one-scheme operation method can be adopted by combining different karst cave distributions, the situation that pore-forming equipment is not matched with karst geology is solved, the construction speed is high, and the environmental protection characteristic is outstanding.
本发明提供一种建筑工程桩基成孔施工方法，具体包括以下步骤：S1、测量与定位：采用全站仪按照设计图纸对桩位进行测量放样，S2、一桩一探：采用工程地质钻机对每一根工程桩位地质情况进行超前钻探，绘制地质柱状图，查清地下溶洞分布范围及地层结构。S3、成孔方式判定：据一桩一探结果，对溶洞分布位置以及溶洞内是否有填充物、填充物的状态、溶洞内是否漏水等情况进行分析，确定成孔方式及相匹配的施工机械设备。本发明建筑工程桩基成孔施工方法的创新工艺做法针对性强，能结合不同溶洞分布采取一桩一方案作业法，解决了成孔设备与岩溶地质不匹配的情况，施工速度快，环保特点突出。
