Foundation pit support structure and construction method thereof
The invention discloses a foundation pit support structure. The support structure is composed of a plurality of steel sheet piles, steel pipe piles, cross beams and I-shaped steel piles. The two steel sheet piles are connected in a meshed mode through the meshing structures of the steel sheet piles, a continuous enclosure structure is formed, and the double functions of water stopping and soil retaining are achieved. The cross section of each steel sheet pile in the length direction is in a Z shape, each I-shaped steel pile is connected to the inner side of one corner of the corresponding steel sheet pile, and each I-shaped steel pile and the corresponding two connected steel sheet piles form a triangular structure. The plurality of steel pipe piles are connected to the I-shaped steel piles at intervals; the steel sheet piles located between every two adjacent steel pipe piles are connected through a plurality of sets of cross beams. The structure and the method disclosed by the invention are flexible and diversified; in practical engineering, flexible selection and arrangement can be achieved according to site conditions, the structure is simple, construction is convenient, implementation is easy, safety is high, and a new thought is provided for the supporting form of canceling an inner support for a deep foundation pit or an ultra-deep foundation pit.
本发明公开了一种基坑围护结构，围护结构由若干个钢板桩、钢管桩、横梁以及工字型钢桩构成；两个钢板桩之间通过其设的咬合结构相互咬合连接，形成连续的围护结构，具有止水与挡土的双重作用；钢板桩沿其长度方向的横截面呈Z字型，工字型钢桩连接在钢板桩其一拐弯处的内侧，且工字型钢桩与两个相连的钢板桩之间构成三角形结构；若干个钢管桩间隔连接在工字型钢桩上；位于相邻的两个钢管桩之间的钢板桩通过多组的横梁相连；本发明所述结构和方法，灵活多样；实际工程中可根据现场情况灵活选择和设置，结构简单，施工方便，易于实施，安全性高，为深基坑或超深基坑取消内支撑的支护形式提供了一种全新的思路。
