Embodiment Construction
[0031] Please check figure 1 and figure 2 , a foundation pit oblique support system, which includes a side wall enclosure structure 100 of the foundation pit, a crown beam 200 connected to the side wall enclosure structure, steel pipe diagonal braces, and corbels; the corbels are fixed on the foundation pit floor, The steel pipe diagonal brace is between the side wall enclosure structure 100 and the foundation pit floor. One end of the steel pipe diagonal brace is fixedly connected to the crown beam 200 and the other end is fixedly connected to the corbel. Usually, a steel plate is pre-embedded on the corbel, and the steel pipe diagonal brace The support is fixedly connected with the corbel through the embedded steel plate.
[0032] For the steel pipe diagonal brace with a large support span, in order to prevent the steel pipe diagonal brace from being unstable due to excessive axial center pressure, a column 12 and a horizontal connecting rod are provided. One end of the co...
