Continuous wall supporting structure adopting large-diameter steel pipe piles and construction method of continuous wall supporting structure
The continuous wall supporting structure adopting the large-diameter steel pipe piles comprises the steel pipe piles arranged at intervals, guide pipes are installed on the outer walls, facing the adjacent steel pipe piles, of the steel pipe piles, connecting pieces with guide grooves are arranged between the adjacent steel pipe piles, and the guide pipes are inserted into the guide grooves; liquid outlet holes are formed in the guide pipe in the vertical direction at intervals, and the grouting pipe and the injection pipe can be inserted into the guide pipe. The grouting pipe is sleeved with the two sealing piece sets, a grouting hole is formed between the two sealing piece sets, and when the grouting pipe is inserted into the guide pipe, the space between the two sealing piece sets forms a grouting chamber. The invention further discloses a construction method of the continuous wall supporting structure. The injection pipe is used for spraying water to the underground and reducing resistance during sinking and pulling out of the steel pipe pile when the steel pipe pile sinks and is pulled out, and the grouting pipe is used for injecting pure cement paste into an external water seepage area through the grouting chamber and solidifying a soil body so as to eliminate the water seepage phenomenon.
本申请公开了一种采用大直径钢管桩的连续墙支护结构，其包括间隔设置的钢管桩，在钢管桩朝向相邻钢管桩的外壁上安装有导向管，并在相邻钢管桩之间设置有具有导向槽的连接件，导向管插入到导向槽内；在导向管上沿竖直方向间隔开设有出液孔，注浆管和喷射管能够分别插入到导向管内；在注浆管上套设有两个密封件组并在两个密封件组之间开设有注浆孔，当注浆管插入到导向管内时，两个密封件组之间的空间形成为注浆室。本申请还公开上述连续墙支护结构的施工方法。喷射管用于在下沉和拔出钢管桩时，向地下喷水，减少下沉和拔出钢管桩时的阻力，注浆管用于将纯水泥浆经注浆室注入到外部的渗水区域，对土体进行固化，以消除渗水现象。
