Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe pile equipment, in particular to a prestressed pipe pile connection device for water transport engineering. Background Art
[0002] Prestressed pipe piles are hollow cylindrical slender concrete prefabricated components made by prestressing and centrifugal forming. They are mainly composed of cylindrical pile bodies, end plates and steel sleeves. Under specific geological conditions, they are driven into the ground by pile drivers to improve the stability of buildings. Prestressed concrete pipe pile foundations are made of prestressed high-strength concrete. They are hollow cylindrical concrete prefabricated components made by prestressing and centrifugal forming processes in professional factories and autoclaved. After being transported to the construction site, they are sunk into the ground by hammering or static pressure as the foundation of buildings (structures). The pile foundation type commonly used in power transmission line projects is bored cast-in-place piles. During the construction of this type of pile, the pipe piles need to be connected and combined. Water leakage is prone to occur at the connection, and when the pipe piles are subjected to external force, the connection is easy to fall off, which makes the connection stability of the pipe piles low. When used for a long time, the pile body may shrink or even break. In addition, it is difficult to handle and the quality of the pile body is not easy to guarantee. To this end, we propose a prestressed pipe pile connection device for water transport engineering. Utility Model Content

By utilizing the special structure of the seal, the outer wall of the seal can be close to the inner wall of the clamp under the action of water flow pressure.
