Construction method of triple-pipe jet grouting pile
The invention relates to a construction method of a triple-pipe jet grouting pile. The construction method comprises the following steps of construction preparation; a drilling machine is in place; stirring the cement paste; drilling a guide hole; rotary jet grouting is conducted, specifically, when a triple-pipe type rotary jet grouting device is adopted for jet grouting, high-pressure water is pumped into a pipe firstly, then cement paste is pumped, and finally compressed air is pumped; and drilling machine displacement. According to the construction method, the high water stopping effect can be guaranteed, the construction cost is saved, vibration and noise generated in the construction process are small, the reinforcing range can be controlled, and the construction method has the advantages of being high in construction efficiency, low in engineering cost and good in reinforcing effect.
本发明涉及一种三重管旋喷桩的施工方法，包括以下步骤：施工准备；钻机就位；水泥浆搅拌；引孔钻进；旋喷注浆，采用三重管式旋喷器进行喷射注浆时，先向管内泵送高压水，再泵送水泥浆，最后泵送压缩空气；钻机移位。本发明的施工方法能够保证较高的止水效果，节约施工成本，施工过程产生的振动和噪音小、可控制加固范围、具有施工效率高、工程造价低、加固效果好的优点。
