Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0030] refer to Figure 1-6 , a prestressed concrete pipe pile, including two fixed pads 1, and four reinforcing ribs 2 are fixedly connected between the two fixed pads 1. It should be noted that the two fixed pads 1 are exactly the same, and the four ribs The upper end of the reinforcing rib 2 is connected with the lower end of a fixed pedestal 1 at the upper position, and the lower ends of the four reinforcing ribs 2 are connected with the upper end of another fixed pedestal 1 at the lower position at the same time, and the two fixed pedestals 1 There are pre-installation mechanism and shaping mechanism respectively;

[0031] The pre-installation mechanism include...

Abstract

The invention discloses a prestressed concrete pipe pile. The prestressed concrete pipe pile comprises two fixed pedestals. According to the prestressed concrete pipe pile, the two fixed pedestals are arranged, and a shaping frame with binding and reinforcing effects is arranged on reinforcing ribs, so that the structural tightness among the four reinforcing ribs is enhanced; a locking lantern ring which is elastically supported by a strong spring and a movable support seat are arranged on the shaping frame through the reinforcing ribs, a driving piston and a driven piston which interact with each other are movably arranged in the movable support seat of a hollow structure in a sleeved mode, and reinforcing sheet metal is connected between the outer edge of a base and the inner edge of an upper outlet, so that the bearing performance and the firmness of the upper and lower ends of the concrete pipe pile are guaranteed; a shaping steel bar is connected between a sleeving plate block and the inner edge of the upper outlet, so that a telescopic connecting rod with an elastic effect is connected between the reinforcing ribs and the shaping steel bar; and the space between the two fixed pedestals is sealed through a shaping cambered plate, so that concrete is poured so as to form a concrete layer, and the fixed pipe pile with prestress is formed.

Description

technical field [0001] The invention relates to the technical field of building component manufacturing, in particular to a prestressed concrete pipe pile. Background technique [0002] In recent years, in response to the call for civilized urban construction, more and more areas have increased their efforts in infrastructure construction. As one of the important components of infrastructure construction, pipe piles have a key impact on the overall construction. Under the existing technology, pipe piles are divided into post-tensioned prestressed pipe piles and pretensioned prestressed pipe piles, prestressed concrete pipe piles, prestressed concrete thin-walled pipe piles and high-strength prestressed concrete pipe piles, pretensioned The prestressed pipe pile is a hollow cylindrical slender concrete prefabricated component made by pretensioning prestressing process and centrifugal forming method. Specifically, pretensioned prestressed concrete pipe piles began to be widel...
