Supporting structure of elevator shaft foundation pit in deep and thick sludge stratum and construction method of supporting structure
The invention discloses a deep and thick sludge stratum elevator shaft foundation pit supporting structure and a construction method thereof.The supporting structure comprises a slope used for supporting and a plurality of grating stirring pile walls, the slope is an inclined slope with an inclined angle on the side wall of a foundation pit, and the bottoms of the grating stirring pile walls are vertically anchored into a hard soil layer to be fixed; the grid mixing pile wall comprises a slope grid mixing pile wall arranged in a slope area and a pit bottom grid mixing pile wall arranged on one side of the foundation pit, and a reinforcing layer is arranged at the joint of the slope grid mixing pile wall and the pit bottom grid mixing pile wall. The reinforcing layer is composed of a plurality of miniature steel pipe piles, each miniature steel pipe pile is located at the joint of the slope grating stirring pile wall and the pit bottom grating stirring pile wall, one side of each miniature steel pipe pile is meshed with the slope grating stirring pile wall, and the other side of each miniature steel pipe pile is meshed with the pit bottom grating stirring pile wall. And the construction cost can be reduced.
本发明公开了一种深厚淤泥地层电梯井基坑支护结构及其施工方法，所述支护结构，包括用于支护的放坡和若干格栅搅拌桩墙，所述放坡为基坑边壁具有倾斜角度的倾斜坡度，所述格栅搅拌桩墙底部竖直锚入坚硬土层中进行固定，所述格栅搅拌桩墙包括装设在放坡区域的坡面格栅搅拌桩墙和装设在基坑一侧的坑底格栅搅拌桩墙，所述坡面格栅搅拌桩墙与坑底格栅搅拌桩墙的连接处设有加固层；所述加固层为若干根微型钢管桩，每根微型钢管桩位于坡面格栅搅拌桩墙与坑底格栅搅拌桩墙的相接处，一侧与坡面格栅搅拌桩墙相互咬合，另一侧与坑底格栅搅拌桩墙相互咬合，本发明既可以保障支护结构的强度，又能降低工程造价成本。
