Multi-section spliced pipe pile and embedding method thereof

Abstract

The invention discloses a multi-section spliced pipe pile and an embedding method thereof, and belongs to the technical field of building structures. The multi-section spliced pipe pile comprises an upper-section pipe pile, a lower-section pipe pile and at least one middle-section pipe pile located between the upper-section pipe pile and the lower-section pipe pile, wherein the pipe piles are connected through connectors; closed grouting chambers defined by upper end plates, lower end plates and force transmission steel pipes are arranged inside the connectors, first grouting holes for communicating with grouting pipes are formed in the upper end plates, and a plurality of extrusion holes for allowing slurry inside the grouting chambers to be extruded out are formed in the force transmission steel pipes; and at least one sleeve is connected between each upper end plate and the corresponding lower end plate and used for providing a channel for allowing the grouting pipes to penetrate through the connectors. Through the above arrangement, each connector of the multi-section spliced pipe pile can be grouted and form an expanded head, so that the pipe pile is provided with the plurality of expanded heads at different heights, and the pressure bearing performance and the pulling resistance of a pile body are improved.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a multi-section spliced ​​pipe pile and its embedding method. Background technique [0002] Prefabricated pipe piles refer to pipe piles made at the construction site or nearby areas, usually with concrete structures, or steel structures, or wooden structures. The prefabricated piles used in China's construction field are mainly concrete prefabricated pipe piles and steel pipe piles. Concrete prefabricated piles can withstand large loads, are strong and durable, and have fast construction speed. They are one of the widely used pile types, but their construction has a great impact on the surrounding environment. Commonly used concrete solid square piles and prestressed concrete hollow pipe piles . Steel piles are mainly steel pipe piles and H-shaped steel piles. [0003] In related fields, the methods of pile sinking mainly include hammering method, static pile pres...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the inability to perform grouting at connection points of different heights in the prior art, and provide a multi-section spliced ​​pipe pile, which aims to use the sleeve on the joint to allow the grouting pipe to pass through the upper joints and connects with joints located below to allow grouting at connection points at different heights
