Supporting structure and method for excavation of foundation pit close to existing building
The invention relates to an excavation supporting structure and method for a foundation pit close to an existing building, and belongs to the technical field of foundation pit supporting, the excavation supporting structure comprises two rows of cast-in-place piles located between a foundation pit to be excavated and the existing building, the two rows of cast-in-place piles are parallel to each other, a top beam is poured at the tops of the cast-in-place piles, and the cast-in-place piles are arranged on the top beam. The length directions of the two rows of crown beams are parallel to each other, a connecting piece is arranged between the two rows of crown beams and comprises first steel supports and anchor cables, the first steel supports are located between the two rows of crown beams, the number of the first steel supports is even, and the anchor cables penetrate through the crown beams close to the foundation pit side and enter the first steel supports. The anchor cable penetrates through the top beam close to the existing building and then returns to the top beam located on the side of the foundation pit through the first steel support, and the two ends of the anchor cable are anchored to the top beam located on the side of the foundation pit. The construction method has the effect of improving the construction efficiency.
本申请涉及一种临近既有建筑的基坑开挖支护结构及支护方法，属于基坑支护技术领域，包括位于待开挖基坑和既有建筑之间的灌注桩，所述灌注桩设置有两排，两排所述灌注桩相互平行，所述灌注桩的顶部浇筑有冠梁，两排所述冠梁的长度方向相互平行，两排所述冠梁之间设置有连接件，所述连接件包括第一钢支撑和锚索，所述第一钢支撑位于两排冠梁之间，所述第一钢支撑的数量为偶数，所述锚索穿过靠近基坑侧的冠梁，进入第一钢支撑内，并穿过靠近既有建筑的冠梁内再通过第一钢支撑返回位于基坑侧的冠梁，所述锚索的两端均锚固在位于基坑侧的冠梁上。本申请具有提高施工效率的效果。
