Construction method of diaphragm wall slotted hole
The invention discloses a construction method of a diaphragm wall slotted hole. The construction method comprises the steps that a percussion drill is adopted to drill a main hole of the slotted hole; an auxiliary hole of the slotted hole is formed by a grab bucket; when the percussion drill drills a first set distance away from the bedrock surface, a unit needs to sample once at least every second set distance and sample once every third set distance from the bedrock surface; and after the bedrock surface is preliminarily judged, sampling is conducted once every fourth set distance, and the depth of the bedrock surface is determined. The construction method of the diaphragm wall slotted hole aims at solving the problem that in the construction process of the diaphragm wall slotted hole, due to the complex geological structure, the excavation accuracy is reduced.
本发明公开了一种防渗墙槽孔的施工方法，包括：采用冲击钻机钻设槽孔的主孔；采用抓斗开设槽孔的副孔；当冲击钻机钻进距基岩面第一设定距离时，机组应至少每第二设定距离取样一次，自基岩面起每第三设定距离取样一次；在初步判定基岩面后，每第四设定距离取样一次，确定基岩面的深度。该防渗墙槽孔的施工方法的目的是解决防渗墙槽孔的施工过程中因地质结构复杂而导致开挖精准度降低的问题。
