Tool type recoverable foundation pit water stop enclosure structure and construction method
The construction method comprises the following construction steps of S1, double-layer steel pipe pile manufacturing, S2, steel pipe pile hole construction, S3, concrete pouring and steel pipe pile static pressure, S4, filling liquid injection of the double-layer steel pipe piles, S5, inter-pile waterproof curtain construction and S6, sleeve valve grouting joint treatment. S7, tool type surrounding purlins and recyclable anchor cables are installed, S8, foundation pit synchronous excavation is conducted, and S9, components and accessories are recycled. An outer pipe and an inner pipe of the double-layer steel pipe slope protection pile are connected through a reinforced body formed by welding a guniting pipe, water suction and a base plate, lubricating liquid is injected through high-pressure splitting of the guniting pipe before the double-layer steel pipe slope protection pile is pulled, the interface of the double-layer steel pipe pile and a concrete body around the pile is broken, and the pile pulling effect and the pile pulling efficiency are effectively improved in cooperation with rotary pile pulling; the double-layer steel pipe slope protection piles, the tool type surrounding purlins, the recyclable anchor cables, the sleeve valve pipes and the like can be recycled, material loss is reduced, and green construction is achieved.
本发明涉及一种工具式可回收型基坑止水围护结构及施工方法，所述施工方法包括如下施工步骤：S1、双层钢管桩制作，S2、钢管桩桩孔施工，S3、灌注混凝土、钢管桩静压，S4、双层钢管桩注入填充液体，S5、桩间止水帷幕施工，S6、袖阀注浆节点处理，S7、工具式围檩、可回收锚索安装，S8、基坑同步开挖，S9、构配件回收；双层钢管护坡桩外管与内管之间通过喷浆管、抽吸水与垫板焊接组成的“加筋体”连接，双层钢管护坡桩在拔桩前通过喷浆管高压劈裂注入润滑液，使双层钢管桩与桩周混凝土体界面破碎，配合旋转拔桩，有效提高了拔桩效果和拔桩效率；双层钢管护坡桩、工具式围檩、可回收锚索、袖阀管等均可回收利用，减少材料损耗，属于绿色施工。
