Construction method of waterproof curtain containing confined water hard stratum and three-shaft mixing pile device
The invention provides a construction method of a waterproof curtain containing a confined water hard stratum and a three-shaft stirring pile device, and relates to the technical field of stirring piles. The construction method of the waterproof curtain containing the confined water hard stratum comprises the following steps that a drill rod with large and small blades arranged at intervals is used for drilling downwards; the drilling speed is kept between 0.8 m/min and 1 m/min; during drilling, the water cement ratio is controlled to be 1.3-1.6, and the cement amount in a single waterproof curtain pile is controlled to be 18-23%, that is, the cement yield per cubic meter of the stirring pile body is 324-414 kg; when the drill is drilled to the bottom, the drill is lifted, and the drill lifting speed is controlled between 0.4 m/min and 0.5 m/min; construction is conducted in a two-stirring and two-spraying mode, and a single waterproof curtain pile is completed; and the closed waterproof curtain is completed through repeated casing drilling construction. The mixing pile device comprises a pile machine body and a mixing pile drill rod; the stirring pile drill rod is arranged on the pile machine body. The technical effects of low manufacturing cost and good waterproof effect are achieved.
本发明提供了一种含承压水硬质地层的止水帷幕施工方法及三轴搅拌桩装置，涉及搅拌桩的技术领域。含承压水硬质地层的止水帷幕施工方法包括以下步骤：使用具有大小叶片间隔设置的钻杆进行下钻；下钻速度保持在0.8‑1m/min之间；下钻时控制水灰比在1.3‑1.6之间，控制单根止水帷幕桩内的水泥量在18‑23％之间，即，每立方米搅拌桩体重水泥产量在324‑414kg之间；待钻至底部时提钻，提钻速度控制在0.4‑0.5m/min之间；采用两搅两喷方式施工，完成单根止水帷幕桩；通过重复套钻施工完成闭合的止水帷幕。搅拌桩装置包括桩机本体和搅拌桩钻杆；搅拌桩钻杆设置在桩机本体上。达到了造价低且隔水效果好的技术效果。
