Problems solved by technology
However, if the bearing capacity of the foundation soil is weak, the effective pile length is too short to meet the bearing capacity requirements, and the effective pile length is too long to be uneconomical; at the same time, the prestressed pipe pile is a friction end-bearing pile, because the pile end area is too small and the end The resistance is small, which affects the bearing capacity of prestressed pipe piles

The invention relates to a PHC pipe pile for post-grouting and a post-grouting construction process thereof, belongs to the technical field of construction, and provides the PHC pipe pile for post-grouting with simple construction, low manufacturing cost and effective improvement of the bearing capacity of a prestressed pipe pile, and the post-grouting construction process thereof. A grouting cylinder is arranged at the bottom of the prestressed pipe pile; multiple grouting holes are formed in the wall of the grouting cylinder; a baseplate is arranged at the bottom of the grouting cylinder; a sealing plate is arranged at the top of the grouting cylinder; and a grouting pipe communicated with the grouting cylinder is arranged in the prestressed pipe pile. The PHC pipe pile for post-grouting is widely applied to the prestressed pipe piles.
Description
technical field [0001] The invention relates to a PHC pipe pile used for post-grouting and a post-grouting construction technology, belonging to the technical field of building construction. Background technique [0002] The prestressed pipe pile is a factory prefabricated reinforced concrete component, which is used as a bearing capacity component of the house foundation, and has high strength and strong bearing capacity. However, if the bearing capacity of the foundation soil is weak, the effective pile length is too short to meet the bearing capacity requirements, and the effective pile length is too long to be uneconomical; at the same time, the prestressed pipe pile is a friction end-bearing pile, because the pile end area is too small and the end The resistance is small, which affects the bearing capacity of the prestressed pipe pile. Contents of the invention [0003] In order to solve the technical problems existing in the prior art, the present invention provides...
