Method for constructing waterproof curtain of deep foundation pit by adopting high-pressure jet grouting pile machine
The invention relates to a method for conducting deep foundation pit waterproof curtain construction through a high-pressure jet grouting pile machine, and relates to the technical field of deep foundation pit waterproof curtain construction. The construction method comprises the steps of construction preparation, surveying and setting out, drilling machine positioning and hole guiding, cast-in-situ bored pile construction, pre-hole-exploring construction, high-pressure jet grouting pile construction and slurry supplementing and checking. On the basis of existing high-pressure jet grouting piles and cast-in-situ bored piles, the situation that only the high-pressure jet grouting piles are adopted for foundation pit waterproof curtain construction in the existing construction process is improved into the situation that the cast-in-situ bored piles are adopted for construction in a soil layer with soft soil texture and small construction difficulty (the upper portion) in a construction area (foundation). High-pressure jet grouting piles are adopted for construction in a (lower) soil layer which is hard in soil texture and large in construction difficulty, so that the construction cost is reduced.
本发明涉及一种采用高压旋喷桩机进行深基坑止水帷幕施工的方法，涉及深基坑止水帷幕施工的技术领域。它包括施工准备，测量放线，钻机就位并引孔，钻孔灌注桩施工，预探孔施工，高压旋喷桩施工，补浆并检查。本发明主要是在现有的高压旋喷桩和钻孔灌注桩的基础上，将现有施工过程中，只采用高压旋喷桩进行基坑止水帷幕施工的情况，改进为在施工区域（地基）土质较软、施工难度较小（上部）土层采用钻孔灌注桩进行施工，在土质较硬、施工难度较大的（下部）土层采用高压旋喷桩进行施工，以减少施工成本。
