Abstract

The invention relates to a waterproof structure of an anti-floating anchor rod for a deep foundation pit and a construction method thereof. The waterproof structure comprises a concrete cushion layer, a waterproof layer and a concrete bottom plate which are sequentially arranged on a foundation, an inserting groove is formed in the upper surface of the concrete bottom plate, the inserting groove extends to the upper surface of the foundation, fixing grooves are formed in the concrete cushion layer, the waterproof layer and the groove wall of the inserting groove located in the concrete bottom plate, a plurality of anti-floating anchor rods are inserted into the inserting groove, telescopic inserting rods are arranged on the side walls of the anti-floating anchor rods, the telescopic inserting rods are matched with the fixing grooves in an inserted mode through fixing mechanisms, every two adjacent anti-floating anchor rods in the length direction of the inserting groove are connected through a connecting piece, and concrete mortar is poured between the side walls of the anti-floating anchor rods and the groove wall of the inserting groove. The waterproof structure has the effect that the convenience is improved when a worker fixes the anti-floating anchor rods.

Description

technical field [0001] The present application relates to the technical field of deep foundation pit construction, in particular to a waterproof structure of an anti-floating anchor for deep foundation pits and a construction method thereof. Background technique [0002] In the waterproof construction of deep foundation pits, concrete cushions and waterproof layers are usually poured sequentially on the foundation of deep foundation pits, and then concrete bottom slabs are poured on the waterproof layer to achieve waterproof effects. For buoyancy, the anti-floating anchor rod is often used to enhance the anti-floating ability of the concrete floor. [0003] The Chinese utility model with the authorized announcement number CN205975608U discloses an anti-floating anchor waterproof structure, including a foundation cushion and an anti-floating anchor arranged on the foundation. The foundation and the foundation cushion are provided with openings, and the anti-floating anchor T...
