Abstract
The invention discloses a support structure for a foundation pit corner position. The support structure comprises a corner connecting part and two layers of purlin structural steel connected to two sides of the corner connecting part through bolts. The corner connecting part is connected with the two layers of the purlin structural steel on two sides of the foundation pit corner respectively, and accordingly mounting convenience is achieved. Besides, sides close to the ends of a first outer purlin structural steel and a second outer purlin structural steel are simultaneously connected with the corner connecting part, thus area of connecting portion is expanded, connection strength is high, and looseness and deformation are less prone to happen. By the corner connecting part which is non-standard connection section, mounting of the purlin structural steel in standard size is facilitated, recycling rate of foundation pit support section is high, and the foundation pit supporting cost is lowered. By three angle brace rods with optimal length ratio, supporting strength of the foundation pit corner position is guaranteed and smaller space of the corner support structure is achieved to facilitate excavation of foundation pit earthwork and improvement of construction efficiency.
