Abstract

The invention relates to an improved anchor rod static pressure pile sealing device. A pile hole of a rectangular pyramid structure is reserved in the middle of a foundation, a pile pressing frame is installed on the part, corresponding the part above the pile hole, of the foundation, the two ends of the pile pressing frame are fixedly installed on the foundation through vertical anchor rods, a section steel beam is transversely installed on the pile pressing frame, a jack is installed on the lower end face of the section steel beam, and the jack and a prefabricated pile under the pile hole are coaxially arranged. The anchor rod static pressure pile sealing device is characterized in that an anchoring framework assembly is installed between the jack and the prefabricated pile and comprises vertical force transmission section steel and transverse anchoring section steel. According to the anchor rod static pressure pile sealing device, by means of the combination of the anchoring framework assembly and a rectangular anchoring iron piece, the pile pressing frame and the jack can be directly replaced after pipe striking is finished, the construction period is effectively shortened, and the circulating rate of construction machines is increased. The anchor rod static pressure pile sealing device is simple in structure, construction is convenient, the circulating rate of the construction machines is increased, and the project machine cost is saved.

Description

technical field [0001] The invention belongs to the field of building construction and relates to static pressure piles, in particular to an improved pile sealing device and construction method for anchor static pressure piles. Background technique [0002] Anchor static pressure piles are widely used in building foundation reinforcement, deflection correction and foundation underpinning because of their convenient construction and high bearing capacity. When the anchor static pressure pile is unloaded and the pile is sealed, the rebound effect of the pile body can easily lead to additional settlement of the building. With the traditional non-unloading pile sealing technology, it takes at least seven days during the construction process to achieve the strength of the pile sealing concrete sufficient to withstand the pre-added reaction force. The time is too long, which prolongs the service life of the equipment to a certain extent. In addition, there are also disadvantages ...
