Structure and construction method for reinforcing oversized sludge deep foundation pit by combining wallboards with composite foundation
The invention discloses a structure and a construction method for reinforcing an oversized sludge deep foundation pit by combining wallboards with a composite foundation, and the construction of a diaphragm wall and a vertical reinforcing body around the foundation pit is carried out before the foundation pit is excavated on site. In the follow-up excavation process, excavation is conducted after supporting, layered excavation is conducted, and symmetrical excavation is conducted. After a foundation is excavated, a high-pressure jet grouting pile construction method is used for transversely reinforcing a soil body, a vertical reinforcing body and adjacent transverse reinforcing areas are connected, finally, a reinforcing plate with a certain thickness in the horizontal direction is formed, the stability and strength of the soil body in the vertical direction can be greatly improved in combination with a stirring pile, and soil body sedimentation is reduced.
本发明公开一种壁板联合复合地基加固超大淤泥深基坑的结构及施工方法，通过在现场基坑开挖前，进行基坑周边地连墙、竖向加固体的施工。在后续开挖过程中，做到先撑后挖、分层开挖、对称开挖。在开挖至基底后，使用高压旋喷桩工法进行土体横向加固，并连接竖向的加固体和各相邻横向加固区域，最终形成水平方向上有一定厚度的强化板，结合搅拌桩，可以使土体在竖向方向上的稳定性、强度大幅提升，减小土体沉降。
