High-pressure jet grouting construction method and construction device
The invention provides a high-pressure jet grouting construction method and a high-pressure jet grouting construction device. The high-pressure jet grouting construction method comprises the following steps: carrying out geological exploration, cleaning surface obstacles, and leveling and hardening a site; measuring and setting out; a hole is led into the soil body through a full casing pipe to form a protection hole, and the perpendicularity of the protection hole is monitored in real time while the hole is led; a protection pipe is inserted into the hole in the vertical direction; arranging a drilling machine, and inserting a jet grouting drill rod into the soil body through the protective pipe; high-pressure water, high-pressure gas and high-pressure slurry are jetted into the soil body through the jet grouting drill rod in a jet grouting mode, and a jet grouting pile is formed in the soil body. According to the method, the guniting speed can be effectively increased, the consumption of cement grout is reduced, the utilization rate of the cement grout and the construction efficiency are improved, the perpendicularity of the drill rod is more accurate, the rotary jet grouting pile with the larger diameter can be prepared, the pile body of the rotary jet grouting pile is free of lap joint and defects, and the quality is better guaranteed.
旋喷桩本发明提供了一种高压旋喷施工方法及施工装置，包括：进行地质勘查、清理地表障碍物，对场地进行平整硬化；测量放线；采用全套管向土体内引孔形成防护孔，在引孔的同时实时监控防护孔的垂直度；向孔洞内沿竖直方向插入防护管；布置钻机，将旋喷钻杆穿过防护管插入土体内；通过旋喷钻杆向土体内旋喷高压水、高压气和高压浆液，在土体中形成旋喷桩。本发明可以有效提升喷浆速度，减少了水泥浆液的消耗量，提高了水泥浆液料利用率和施工效率，钻杆垂直度更精确，可以制备得到直径更大的旋喷桩，旋喷桩的桩体无搭接无缺陷，质量更有保证。
