PHC (prestressed concrete pipe pile) pile streamline conveying production line

Abstract

The invention belongs to a production process of a PHC pile and relates to a PHC pile streamline conveying production line. The production line is characterized by comprising a whole production workshop formed by a left area, a middle area and a right area, wherein from the front part to the back part of the workshop, the left area is sequentially provided with a blending floor, an end plate processing area, a steel reinforcement cage, an end plate assembling area and a steel reinforcement cage roll welding area, the middle area is sequentially provided with a concrete spreading area, a cage loading area, an oil spraying pool, a die-cleaning pool, a die-detaching area, and a steel rod precisely cutting and heading area, and the right area is sequentially provided with a tensioning area, a centrifugal molding area, a steaming area, a pipe pile expanding area, a product inspection and code-spraying identifier area, a to-be-high pressure steamed semi-finished pipe pile storing area and a high pressure kettle-entering transition carriage pit. The production line has the beneficial effects that plane circular arrangement is adopted, and the occurrence rate of accidents is reduced due to the adoption of a stereo lifting technical mode that the upper surface and the lower surface are mutually moved; and due to the adoption of a slope platform and a slope rail, the pipe pile is moved, the distance of carriage movement is greatly shortened, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the production technology of PHC pipe piles, and in particular relates to a highly automatic, efficient and safe PHC pipe pile flowing water transmission production line. Background technique [0002] PHC piles, that is, prestressed high-strength concrete piles, are produced by professional manufacturers, using advanced techniques such as pre-tensioning prestressing, adding finely ground materials, and high-efficiency water reducing agents. A slender hollow prefabricated concrete member of equal cross-section made by steam curing. It has been more than 20 years since my country's first pipe pile production line was introduced in 1987. There are nearly 500 pipe pile manufacturers and more than 300 related enterprises in the country. The output value of the prestressed concrete pipe pile industry chain can reach 30 billion yuan. There are only a handful of cement concrete industries in China. However, the pipe pile industry is s...

Problems solved by technology

[0012] (1) This production process needs to close the mold first and then distribute the material. The hydraulic system of the pump is used to provide a pressure of about 7Mpa, and the concrete is distributed through the pumping pipe extending into the tail hole of the pipe mold. The workability of the concrete is high, so the mixing The water-cement ratio and slump of the concrete produced are relatively large, and the produced pipe piles are prone to shrinkage cracks, which reduces the strength and durability of the piles;

[0013] (2) The concrete is distributed after the mold is closed. The amount of concrete distribution in the steel mold is not easy to check, and the uneven distribution is not easy to find, which will lead to the problem of excessive wall thickness deviation of the pipe pile and affect the quality of the pipe pile;

[0014] (3) In this production process, the reinforcement cage, end plates, and head and tail plates all need to be lifted to the second floor plane for fabrication or assembly, and the pipe mold needs to be lifted and lowered multiple times, so energy consumption is high, resulting in increased production costs;

[0015] (4) The pipe mold of this production process has a long moving distance and low production efficiency;

[0016] (5) Part of the factory building is divided into two floors by the cage rib production area, which affects the lighting and visibility in the factory building, and is prone to safety accidents
