针对早期修建的中小型水库土石坝存在的渗漏隐患问题,采用高压旋喷桩进行加固处理,通过确定合理的设计与施工参数,对施工中的质量控制措施严格掌控,来提升高压旋喷桩的施工质量。最后通过开挖检查、钻孔取芯、压水试验三种方法对施工质量进行了检验,结果表明桩体均匀性和桩体完整性均较好,墙体搭接良好,没有夹泥或缺喷等问题,抗压强度和渗透系数均能满足设计要求。 In view of the potential leakage problems of small and medium-size reservoir earth-rock dams which were built in the early stage, high-pressure rotary jet grouting piles are used for reinforcement treatment. By determining reasonable design and construction parameters and strictly controlling the quality control measures in construction, Construction quality. Finally, the construction quality has been tested by excavation inspection, drilling coring and water pressure test. The results show that the pile body uniformity and pile integrity are good, the wall lap joint is good, there is no mud or lack Spray and other issues, compressive strength and permeability coefficient can meet the design requirements.
