Grout outflow prevention construction method under karst geological condition
The invention discloses a grout outflow prevention construction method under a karst geological condition, and relates to the technical field of foundation reinforcement. The grout outflow prevention construction method under the karst geological condition comprises the following steps: S1, a site is leveled, measurement, positioning and paying off are conducted, U-shaped steel sheet piles are driven into the boundary of the construction site at equal intervals, the model of each U-shaped steel sheet pile is 750 * 205 (width * height), and the wall thickness of each U-shaped steel sheet pile is 10 mm. According to the grout outflow prevention construction method under the karst geological condition, in order to prevent adjacent area pollution and material waste caused by grout outflow, a lateral grout outflow prevention device is arranged at the boundary of a construction site, a waterproof curtain is formed, grout outflow is prevented, and a horizontal grouting reinforcing body is poured in an area defined by the lateral grout outflow prevention device, so that the problem that in the karst foundation grouting reinforcement process, grout laterally flows outwards, and underground water is polluted is thoroughly solved.
本发明公开了一种岩溶地质条件下的防浆液外流施工方法，涉及地基加固技术领域。该岩溶地质条件下的防浆液外流施工方法，包括如下步骤：S1、平整场地，测量定位放线，在施工场地边界等间距间隔打入U形钢板桩，其中U形钢板桩型号为750×205(宽度×高度)，壁厚为10mm。该岩溶地质条件下的防浆液外流施工方法，为防止由于浆液外流而导致的相邻区域污染和材料浪费，在施工场地边界设置一种侧向防浆液外流装置，形成隔水帷幕，防止浆液外流，在侧向防浆液外流装置围合区域内浇筑水平注浆加固体，从而彻底解决岩溶地基注浆加固过程浆液侧向外流、污染地下水的问题。
