Assembly type deep foundation pit supporting structure and construction method thereof

Abstract

The invention discloses an assembly type deep foundation pit supporting structure. The assembly type deep foundation pit supporting structure comprises a large-head anchor rod, a hanging plate, a concrete block and a nut; the outer figure of the concrete block is in a conical platform shape; the axis position of the concrete block is provided with a through hole; the hanging plate is provided withan accommodating hole which is matched with the concrete block; the upper end of the hanging plate is provided with a first butting body; the lower end of the hanging plate is provided with a secondbutting body; the first butting body is matched with the second butting body; the concrete block is arranged inside the accommodating hole; the large-head end of the large-head anchor rod is insertedinto a soil slope of a deep foundation pit; the threaded end of the large-head anchor rod penetrates through the through hole; the nut is connected with the threaded end of the large-head anchor rod;a gasket is arranged between the nut and the concrete block; and the part, higher than the nut, of the large-head anchor rod is in threaded connection with a water stop bolt in order to fix a shear wall template. According to the assembly type deep foundation pit supporting structure disclosed by the invention, the hanging plate is prefabricated, industrial standardized production can be realized;the productivity is increased; the labor investment and cost are reduced; most steps in the construction method are assembly type construction; the operation is simple; and quality is controllable.

Description

technical field [0001] The invention relates to the field of deep foundation pit support, in particular to an assembled deep foundation pit support structure and a construction method thereof. Background technique [0002] Supporting structures are required in deep foundation pits of both industrial and civil buildings. The existing supporting system is reinforced mesh and anchor nails for slope protection. This supporting system is all operated on site, which requires a large labor investment and high cost. Reinforced concrete If the dosage is large, the effect of energy saving and emission reduction cannot be achieved. Therefore, there is an urgent need for an assembled deep foundation pit support structure and its construction method to realize industrialized standardized production, improve productivity, reduce labor input and cost, and achieve energy saving, emission reduction, and low carbon consumption. Contents of the invention [0003] The purpose of the present ...
