Waterproof construction method for PC composite pile enclosure structure
The invention discloses a PC composite pile enclosure structure which is composed of first steel pipe piles, Larsen steel sheet piles, second steel pipe piles, steel enclosing purlins, pull rods, bracket supports, composite geomembranes, geogrids and geotechnical cloth. The first steel pipe pile and the Larsen steel sheet pile are assembled and combined into a lock catch structure through a locking opening to be arranged on the upstream side. The second steel pipe pile is arranged on the downstream side. Pull rod holes are formed in the steel pipe pile 1 and the steel pipe pile 2; the steel enclosing purlin is arranged above the bracket bracket; the invention further provides a waterproof construction method of the PC composite pile enclosure structure, and the waterproof construction method comprises the steps of laying a composite geomembrane, a geogrid and geotechnical cloth, constructing a waterproof curtain wall, performing compaction grouting construction and the like. A series of problems that a traditional cofferdam is insufficient in impermeability, poor in sealing performance and the like are effectively solved while the structural rigidity is met, and the cofferdam has great popularization value.
本发明公开了一种PC组合桩围护结构，由钢管桩1号、拉森钢板桩、钢管桩2号、钢围檩、拉杆、牛腿支架、复合土工膜、土工格栅、土工布组成；钢管桩1号与拉森钢板桩通过锁口拼装组合为锁扣结构设置于迎水侧；钢管桩2号设置于背水侧；钢管桩1号1、钢管桩2号3均设置有拉杆孔；钢围檩设置于牛腿支架上方；拉杆贯穿于钢管桩1号、钢管桩2号、钢围檩，本发明同时提供了一种PC组合桩围护结构防水施工方法，包括复合土工膜、土工格栅、土工布铺设，止水帷幕墙以及压密注浆施工等步骤。本发明在满足结构刚度的同时有效解决了传统围堰抗渗性不足、密封性不好等一系列问题，极具推广价值。
