Novel section prestressed concrete pipe pile

Abstract

The invention relates to the field of concrete pipe piles, and discloses a novel section prestressed concrete pipe pile. The novel section prestressed concrete pipe pile comprises a pipe body and a supporting frame, the pipe body comprises a top pipe, a first connecting pipe, a second connecting pipe, a third connecting pipe and a bottom pipe, and the first connecting pipe is installed at the bottom of the top pipe. According to the novel section prestressed concrete pipe pile, a complete pipe pile can be formed through the pipe body composed of the top pipe, the first connecting pipe, the second connecting pipe, the third connecting pipe and the bottom pipe, so that the pipe body is more convenient to use, the outer diameter of the pipe body is irregular, and therefore, the pipe body is better in dispersion effect on pressure transmitted to the outside; in this way, the influence of external force on the pipe body is smaller, then the strength of the whole pipe body can be greatly improved, and the service life of the pipe body is prolonged; and the pipe body can perfectly meet the installation requirements of the different areas due to irregular shape when the pipe body is used in different areas, and the pipe body can further meet the use requirements of the different areas.

Description

technical field [0001] The invention relates to the field of concrete pipe piles, in particular to a novel section prestressed concrete pipe pile. Background technique [0002] Prestressed concrete pipe piles are mainly used in foundation engineering, and are widely used in building foundations and soft soil foundations. Prestressed concrete pipe piles have the advantages of low cost, high single pile bearing capacity, controllable quality, convenient transportation and wide range of design options. At present, the section form of prestressed concrete pipe pile is mainly ring section. With the continuous development of my country's civil engineering industry, the geological environment of engineering projects is relatively complex, and the application of pipe piles with a single section form is limited, especially in soft soil areas. Due to the poor soil layer and deep bearing layer, the bearing capacity of prestressed concrete pipe piles is mainly provided by side friction ...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a new cross-section prestressed concrete pipe pile, which solves the problem that the shape of the common prestressed concrete pipe pile is relatively single, and in different application scenarios, the influence of external forces is different. The problem that cracks are prone to occur when prestressed concrete pipe piles are subjected to severe external forces
