Embodiment Construction

[0016] refer to figure 1 and figure 2 , a prestressed tubular pile composite structure of the present invention includes a pile body 1 and a pile connector 2 . The pile body 1 is hollow cylindrical, and internal threads 5 are provided on the inner walls of both ends of the pile body 1 . Considering that the pile body 1 is made of concrete material, in order to set the internal thread 5 more conveniently, the two ends of the pile body 1 can be fixedly sleeved with a nut 6 with a matching shape. The nut 6 is made of cast iron material, and the internal thread 5 is located on the nut 6.

[0017] The pile connector 2 of the present invention is generally also made of cast iron. The middle part of the pile connector 2 is a cylindrical part, and the outer circumference of the cylindrical part is provided with an external thread 7 matching the internal thread 5 on the inner wall of the pile body 1, and the pile connector 2 can be screwed into the pile body 1 through the external ...

Abstract

The invention discloses a prestressed pipe pile combined structure which comprises a pile body and a pile connector. The pile body is in a hollow cylinder shape. Internal threads are arranged on the inner side walls at the two ends of the pile body. The pile connector comprises a cylindrical part arranged in the middle portion and pointed cones arranged at the two ends, wherein external threads matched with the internal threads on the inner side wall of the pile body are arranged on the periphery of the cylindrical part, and the pile connector is screwed to one end of the pile body through the cylindrical part. In the use process, all pipe piles can be spliced through corresponding pile connectors conveniently, after the lower end of the pipe pile located at the lowest portion is connected with the corresponding pile connector, the pointed cone at one end of the pile connector will be exposed, and the pipe pile can more conveniently sink into the underground stratum through the corresponding pointed cone. Therefore, the prestressed pipe pile combined structure can be combined and spliced flexibly, construction is convenient, and complexity and cost of design and construction are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a prestressed pipe pile composite structure. Background technique [0002] Prestressed pipe piles are widely used in foundation engineering of modern buildings. Especially for buildings and infrastructure projects built on unstable soil layers or soft soil layers, prestressed pipe piles support the buildings and ensure their safety by transferring the load of the buildings to the stable rock layers underground. [0003] At present, the length of pipe piles is generally between 5m and 15m, and multiple pipe piles are generally required to be spliced ​​and used during construction. In order to sink the bottom pipe pile into the ground better, the lower end of the pipe pile is generally set in a pointed cone structure to facilitate the pipe pile to be pressed into the underground soil layer, while the top end of the pipe pile is connected to another pipe pile throu...
