Construction method for preventing concentrated leakage of cofferdam
The invention relates to the technical field of cofferdam construction, and provides a construction method for preventing concentrated leakage of a cofferdam, which comprises the following steps: S1, carrying out detailed geological survey on a construction area to obtain parameters such as soil layer distribution, underground water level and soil permeability coefficient; s2, designing a composite cofferdam structure according to a geological survey result; s3, cofferdam construction is conducted; s4, the cofferdam is monitored regularly, monitoring data are transmitted to a monitoring center in a wireless mode, and if abnormity is found, reinforcement measures are taken in time; and S5, when concentrated leakage is found, a double-liquid grouting method is adopted for blocking, grouting materials are cement paste and water glass, and the proportion of the cement paste and the water glass is determined according to a field test. The composite cofferdam structure is accurately designed through detailed geological survey and three-dimensional geological model analysis, the waterproof performance of the cofferdam is effectively improved, and the stability and the pressure resistance of the cofferdam are enhanced by adopting the mode of combining the high-strength concrete cast-in-place piles, the waterproof geotechnical cloth and the steel sheet piles.
本发明涉及围堰施工技术领域，提供围堰防集中泄露的施工方法，包括以下步骤：S1.对施工区域进行详细的地质勘察，获取土层分布、地下水位及土壤渗透系数等参数；S2.依据地质勘察结果，设计复合围堰结构；S3.进行围堰施工；S4.定期对围堰进行监测，监测数据通过无线传输至监控中心，若发现异常，及时采取加固措施；S5.当发现集中泄露时，采用双液注浆法进行封堵，注浆材料为水泥浆和水玻璃，其配比根据现场试验确定。通过详细的地质勘察和三维地质模型分析，精确设计复合围堰结构，有效提高了围堰的防水性能，采用高强度混凝土灌注桩、防水土工布和钢板桩相结合的方式，增强了围堰的稳定性和抗压能力。
