Foundation pit supporting structure adjacent to underground engineering and construction method thereof
The invention provides a foundation pit supporting structure adjacent to underground engineering and a construction method of the foundation pit supporting structure, and relates to the field of foundation pit supporting. The foundation pit supporting structure comprises a first-layer supporting structure, a second-layer supporting structure, a third-layer supporting structure and a fourth-layer supporting structure, the first-layer supporting structure is arranged on the edge of a foundation pit in a surrounding mode, the second-layer supporting structure is arranged on the inner side of the first-layer supporting structure in a surrounding mode, and the third-layer supporting structure is arranged on the inner side of the second-layer supporting structure in a surrounding mode; the four-layer supporting structure is in a step shape with the outer portion higher than the inner portion, a first waist beam is arranged on the inner side of the first-layer supporting structure, a second top beam is arranged on the upper portion of the second-layer supporting structure, a first connecting structure is arranged between the first waist beam and the second top beam, and the space between the first-layer supporting structure and the second-layer supporting structure is filled with interlayer soil. A cement mixing pile reinforcing structure is arranged in the interlayer soil body, so that the strength and the water stopping performance of the interlayer soil body are improved, and the interlayer reinforcing area plays a role in effectively supporting the first layer of supporting structure.
本发明提供了一种邻近地下工程的基坑支护结构及其施工方法，涉及基坑支护领域。该基坑支护结构包括第一层支护结构、第二层支护结构、第三层支护结构和第四层支护结构，第一层支护结构围设于基坑的边缘，第二层支护结构围设于第一层支护结构的内侧，第三层支护结构围设于第二层支护结构的内侧；四层支护结构呈外高内低的台阶形，第一层支护结构的内侧设有第一腰梁，第二层支护结构的上部设有第二冠梁，第一腰梁与第二冠梁之间设有第一连接结构，第一层支护结构与第二层支护结构之间填充有层间土体，层间土体中设置有水泥搅拌桩加固结构，提高了该部分层间土体的强度和止水性能，层间强化区域对第一层支护结构起到有效支撑。
