Prestressed Concrete Spun Pile

Supplier: Prestressed concrete spun pile with diameter from 600-1400mm and single length upto 45m

Working Principle¡êo Centrifugal Spinning Machine for spun concrete pole & pile is driven by variable speed AC Motor. High centrifugal force extracts the excess water from the fresh concrete placed in the mold. This process makes the concrete extremely denser. This in turn improves the quality of the concrete. The pole produced will have smooth surface with void cross-section. The spinning process starts with slow revolution. The concrete will be distributed uniformly over the full length of the mold. Following that, the revolution increases automatically to medium speed and finally to high speed. At the highest speed, a large magnitude of centrifugal force (~30g) acts to compact the concrete, and form the Standard quality poles. diameter 130-390mm

Introduction This pre-stressed concrete spun pole production line is designed in accordance with annual production capacity of 36, 000pcs various medium-sized cone pre-stressed steel concrete poles. As far back as the 1930s, the people?s republic of china used armored concrete pole. With the rapid development of power industry, the production and use of concrete pole has developed tremendously thereupon. Pre-stressed concrete pole develops rapidly because of much superiority. Compared with common concrete pole, its advantage is as follows: Economizing steel in a large amount, about 30%~70% (adopting cold drawing can economize 30%~60%; in case of steel wire of high strength, economize 40%~69%) Crack resistance is improved by 3~5 times Steel performance can be improved by 1~3 times Reduction of cost (adopting cold drawn wire can economize 25%~40%; in case of steel wire of high strength, economize12%~21%) Good endurance can delay the appearance and expansion of cracks Protecting the environment that mankind depends on for existence, and reducing deforestation. Pre-stressed concrete poles are strictly in accordance with two standards: gb396-94 annular armored concrete pole and gb4623-94 annular pre-stressed concrete pole of the people?s republic of china.

Overview This Pre-stressed Concrete Spun Pile Steel Mould is used for making concrete pipe. It is in accordance with the standard GB13476-1999, the quality is guaranteed. Our main product, GM mould series and forming sets of centrifugal machine sell well in GuangDong, ZheJiang, ShangHai, JiangSu, FuJian, HeBei and other places in china. Working Principle 1. This spun pile steel mould shall operate together with pile spinning machine. 2. This mould forms pile under the force of centrifugal. There are longitude stiffeners and latitude stiffeners on the mould surface. 3. The mould rotates in high speed under the motor driven. The redundant water in the slurry is released by the force of centrifugal, and the concrete is dense and high in strength. And the spun pile is formed around the inner wall of the mould.
