Support structure for supporting foundation pit and method for supporting foundation pit
The invention discloses a support structure for supporting a foundation pit and a method for supporting the foundation pit. The support structure comprises a bored pile (2), a top beam (3) and a breast beam (4) poured at the top and the middle of the bored pile respectively, a steel plate (5) pre-buried on the breast beam, an embedded part (8) pre-buried in a concrete cushion course (9) at the bottom of the foundation pit, an inclined steel pipe (6), a grouting hole (10) formed in the upper part of the steel pipe, and seriflux (7) filled in the steel pipe, wherein two ends of the inclined steel pipe (6) are welded on the steel plate and the embedded part respectively. According to the invention, the bored pile, the top beam, the breast beam and the steel pipe form a stress conversion system, and the pressure resistance and self weight of the seriflux, or concrete or gravel are fully utilized, so that a stress system is stable, safe and reliable, and can ensure safety of construction staff. The construction difficulty is small, the construction efficiency is high, and the material cost is low.
