The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-6, a prefabricated foundation pit supporting structure comprises a vertical column 1, an installation part 2, an inclined strut part 3 and a stop piece 4; the upright post 1 is vertically arranged; the two mounting parts 2 are respectively fixed on two sides of the upright post 1; the mounting part 2 comprises a vertical side plate 21 fixed with the upright post 1 and a mounting beam 22 horizontally fixed at the upper end of one side of the side plate 21 far away from the upright post 1; the inclined supporting part 3 is obliquely fixed between the side plate 21 and the mounting beam 22; the inclined supporting part 3 comprises an inclined supporting beam 31 which is obliquely arranged and two supports 32 which are respectively fixed at two ends of the inclined supporting beam 31; one support 32 is fixed with the outer side surface of the side plate 21, and the other support 32 is fixed at the lower end of the mounting part 2; the support 32 is positioned at the lower end II, and the lower end of the support is flush with the lower end of the side plate 21; the stop piece 4 is arranged on the outer side surface of the upright post 1; the upper end surface of the stop piece 4 abuts against the lower end surface of the side plate 21. A cross beam or a longitudinal beam is fixed on the mounting beam 22 of the mounting part 2; the inclined support part 3 is arranged between the side plate 21 and the mounting beam 22 and plays a role in supporting; the stop piece 4 is fixed on the outer side surface of the upright post 1 and positioned on the side plate 21, and plays a role in supporting and fixing the side plate 21, so that the side plate 21 is prevented from falling down, and the cross beam and the longitudinal beam are prevented from being crushed.

In particular, the upright 1, the mounting beam 22 and the raker beam 31 can be made of i-steel, but the end of the raker beam 31 needs to be fixed with a steel plate to be fixed with the support 32.

Preferably, the support 32 is a triangular prism. In particular, the support 32 is a right triangular prism.

Further, the stop member 4 comprises a stop block 41 and a lower fixing member 45 in sequence from top to bottom; a fixing rod 42 is vertically fixed at the lower end of the middle part of the block 41; the lower fixing piece 45 is fixed on the outer side of the side plate 21, and a through hole for the fixing rod 42 to pass through is formed in the middle of the lower fixing piece 45; the fixing rod 42 is sleeved in the through hole of the lower fixing member 45.
