Pretensioned prestressed concrete pile machine

Centrifugal spinning machine for prestressed spun concrete pile is a kind of mold equipment, which is a mainly forming equipment used for producing circular prestressed concrete piles, square prestressed concrete piles and other cement products with a variety of different diameter and length.

2. Working Principle of Heavy Concrete Pile Spinning Machine

1)   Spun pile mold rotates with Centrifuge, there are longitude stiffeners and latitude stiffeners around the surface.

2)   The redundant water in the concrete is released under the force of centrifuge and concrete gets dense and high strength.

3. Features of Heavy Concrete Spun Pile Spinning Machine

(1) Saving a great deal of steel, about 30~70% (employ cold-drawn steel wire can save 30%~60%; employ high stress steel wire can save 40%~69%).

(2) Reducing the cost (using cold drawn steel wire can reduce 25%~40%; using high stress steel wire can reduce 12%~21%).

(3) Good durability, can delay the existence and expansion of cracks.

1. Overview of Prestressed Concrete Spun Pile Mold

Prestressed Concrete Spun Pile Mold is used for prestressed concrete pile production. Its mainly manufacture technology is longitudinal tension by steel wires. Then it can squeeze out the excess water in the concrete with centrifugal force. Thus, it can greatly improve the concrete density and strength.

2. Appearance quality of Prestressed Concrete Pile Mold

(1)   Outside surface of concrete pile mold should not have rag, sharp edge, welding slag and damage, etc.

(2)   Dislocation between welded splice and binding face should not be greater than 1mm.

(3)   After bolts are tightened, nuts should be exposed. The length should not be more than 15mm.

(4)   Longitudinal stiffened plates, circular configuration should be flat.

(5)   Requirements of coating of pile mold surface should be conformed to terms of JC/T 402.
