A high-strength concrete pipe pile and its forming device

Abstract

The invention relates to the field of concrete pipe piles, in particular to a high-strength concrete pipe pile and a forming device thereof. The pipe pile includes an outer pipe and an inner pipe, and the outer pipe and the inner pipe are arranged concentrically. The molding device includes a moving mechanism and a limiting mechanism. A discharge barrel is arranged on the side of the moving mechanism and the limiting mechanism. A water-filling barrel and a feeding barrel are connected to each other on both sides of the discharging barrel. A drainage mechanism is arranged in the feeding barrel. A mixing driving mechanism is arranged on the side of the discharge barrel, and a first stirring part and a second stirring part are arranged on the mixing driving mechanism. The forming device designed in the present invention limits the position of the pipe piles through the limit mechanism, stirs and mixes the concrete raw materials driven by the mixing drive mechanism, realizes intermittent feeding, and pours the pipe piles one by one, which can further improve work efficiency.

Description

technical field [0001] The invention relates to the field of concrete pipe piles, in particular to a high-strength concrete pipe pile and a forming device thereof. Background technique [0002] Prestressed concrete pipe piles have been widely used in engineering as the foundation of civil engineering such as building structures and bridge structures due to their high single pile bearing capacity and convenient construction. Prestressed concrete pipe piles can be divided into post-tensioned prestressed pipe piles and pretensioned prestressed pipe piles: pretensioned prestressed pipe piles are hollow cylinders made by pretensioning prestressing technology and centrifugal forming method Slender concrete prefabricated components, mainly composed of cylindrical pile body, end plate and steel ferrule. The post-tensioning method is to apply prestress through the internal reserved holes after the initial setting of the concrete in the pipe pile. [0003] The molding method in the ...

AI Technical Summary

Problems solved by technology

[0003] The forming method in the prior art includes steps such as binding of steel cages, entering the mold, pouring, centrifuging, and steaming. The steps are cumbersome and need to be carried out separately in multiple steps, which reduces the work efficiency

Concrete can only be poured after mixing and mixing, and there are still working gaps during pouring, which requires manual operation, which will reduce work efficiency
