Abstract

The utility model discloses a foundation pit supporting formwork which comprises a connecting supporting top plate, fixing inserting rods are fixedly connected to the two sides, close to the middle, of one side face of the connecting supporting top plate and the middle of the connecting supporting top plate, and an auxiliary gap filling unit is connected to one end of each fixing inserting rod in an inserted mode. Back insertion type fixed plates are fixedly connected to the two sides, close to the middle, of the other side face of the connecting and supporting top plate, and a bottom supporting butt strap is fixedly connected to the bottom of one side face of the connecting and supporting top plate. The back insertion type fixed plate is installed on the side face of a foundation, when the connecting and supporting top plate is fixedly installed at the bottom of the foundation, the abutting butt strap makes contact with the side face of a pile foundation, the slidable adjusting rod conducts backward limiting sliding on the main body limiting shaft rod, and then the slidable adjusting rod extrudes and adjusts the telescopic spring; and the telescopic springs are adjusted to perform corresponding compression adjustment, so that the width interval gaps of the inner wall of the foundation pit are effectively filled, and the stability of the pile foundation is enhanced.
