Construction method of water stop enclosure structure of soft soil foundation building foundation pit
The invention discloses a construction method of a water stop enclosure structure of a soft soil foundation building foundation pit, which comprises the following specific operation steps: S1, leveling a site, marking along the edge of the building foundation pit, and forming holes in enclosure piles at equal intervals along the marking through a rotary drilling rig; s2, steel bars are bundled to a steel reinforcement cage, and concrete and the steel reinforcement cage are used for stretching out the prefabricated splicing type fender post; s3, underground water generated in the fender posts is pumped out through a water pump, and the prefabricated bottom-layer fender posts are vertically placed in the fender post holes through hoisting equipment; the prefabricated fender posts are used, the bottom-layer fender posts are placed at the bottoms of the fender post holes, then the middle-layer fender posts are placed and installed one by one, collapse of the fender posts can be prevented by installing the fender posts in time, the waiting time needed by concrete solidification is shortened by prefabricating the fender posts, the construction efficiency is improved, and the construction cost is reduced. And the prefabricated fender posts are spliced, so that the hoisting operation is relatively simple.
本发明公开了软土地基建筑基坑的止水围护结构的施工方法，具体操作步骤如下：S1、场地整平，沿建筑基坑的边缘进行标线，通过旋挖钻机沿标线等距进行围护桩成孔；S2、将钢筋捆扎至钢筋笼，并使用混凝土与钢筋笼伸长出预制拼接式围护桩；S3、将围护桩内部产生的地下水通过水泵抽出，通过吊装设备将预制的底层围护桩竖直放置进围护桩孔的内部；本申请通过使用预制围护桩，通过将底层围护桩放置在围护桩孔的底部，再将中层围护桩逐个放置安装，通过及时将围护桩安装，能够防止围护孔产生坍塌，通过预制围护桩，减少混凝土固化所需的等待时间，使得施工效率提高，并且由于预制围护桩为拼接式，使得吊装操作较为简单。
