pile connection structure

Abstract

The invention discloses a pile body connection structure. The pile body connection structure comprises an upper pile body and a lower pile body, wherein an upper metal pipe is sleeves and fixedly arranged at the lower end of the upper pile body, and a lower metal pipe is sleeves and fixedly arranged at the upper end of the lower pile body; the lower end of the upper pile body and the upper end ofthe lower pile body are aligned with each other, fixed narrow plates are arranged on the upper metal pipe and the lower metal pipe in a vertical welding mode, and at least three fixed narrow plates are fixedly welded on the upper metal pipe and the lower metal pipe. According to the pile body connection structure, due to the fact that the upper metal pipe and the lower metal pipe are directly integrally cast and formed with the pile body when the pile body is manufactured, the upper metal pipe and the lower metal pipe can be welded and fixed by the fixed narrow plates, and therefore the upperpile body and the lower pile body corresponding to the upper metal pipe and the lower metal pipe are connected; the fixed pile body connecting structure is extremely convenient to construct, and the resistance of the soil body to the fixed narrow plate is extremely small when the pile body is arranged in the soil body, so that the pile body can be conveniently arranged in the soil body.

Description

technical field [0001] The invention relates to a pile body connection structure, which is mainly used for the fixed connection of centrifugally prestressed pipe piles, square piles and prestressed non-centrifugal piles. Background technique [0002] The traditional pile body connection structure generally includes flange connection plates fixed at the ends of the upper pile body and the lower pile body. The flanges of the upper pile body and the lower pile body are connected by welding. The main reason is that the welding part is weak and the long-term durability is poor , and the tensile and horizontal bearing capacity is low, which is easy to cause damage to the connection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pile connection structure, which has a stronger structure and less resistance in the soil. [0004] For this reason, the pile connection structure provided by the present invention includes...
