Abstract

The invention discloses a retard-bonded prestressed uplift pile connecting device and a construction method thereof, and aims to provide the retard-bonded prestressed uplift pile connecting device capable of effectively avoiding a problem of water seepage of a basement bottom plate as a result of water seepage between a sleeve and the basement bottom plate under the condition that the anti-floating requirement of a basement is met as well as a construction method thereof. The retard-bonded prestressed uplift pile connecting device comprises anchoring steel bars anchored in the basement bottom plate; an uplift pile located below the basement bottom plate; a lower prestressed anchoring device which comprises a lower anchorage device embedded in the lower portion of the uplift pile, a prestressed anchorage device fixed to the top of the uplift pile and a retard-bonded prestressed steel strand, wherein the retard-bonded prestressed steel strand comprises a lower prestressed steel strand connecting the lower anchorage device and the prestressed anchorage device; and an adapting piece connected with the prestressed anchorage device, wherein the anchoring steel bar is connected with the adapting piece.

Description

technical field [0001] The invention relates to an anti-floating device for a basement, in particular to a slow bonding prestressed anti-lift pile connection device and a construction method thereof. Background technique [0002] With the vigorous construction of infrastructure in our country, the requirements for anti-floating of basements are getting higher and higher. Among them, the prestressed pile using slow bonding prestressing technology has the advantages of good durability, high bearing capacity, and low cost compared with ordinary pile types, and has been widely used in recent years. [0003] Slowly bonded prestressed piles generally consist of concrete piles, slowly bonded prestressed steel strands, and prestressed anchorage systems, wherein the slowly bonded prestressed steel strands include prestressed The casing and the retarding adhesive between the prestressed steel strand and the casing. The slow-bonding prestressing technology can ensure that the steel s...
