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.

In order to form the concrete more quickly to meet the design strength of more than 70%, steam curing can be carried out so as to shorten the mold-releasing cycle.

We have two categories of prestressed spun concrete pile molds: circular concrete pile steel mold and square concrete pile steel mold.

2. Features of Prestressed Concrete Pile Mold

2.1 Welding technology, which enhances the smooth finish of the mold wall, and eliminates the uneven traces of rivet holes. So the concrete poles appearance will be improved significantly.

2.2 The cylinder is changed to U-type longitudinal stiffeners which can greatly increase the stiffness and flexural strength of the steel mold.

2.3 Install the slot with rubber sealing strip, in order to prevent leakage to ensure quality.

3. Working Principle of Prestressed Concrete Pile Mold

3.1 The steel mold should work together with heavy prestressed pile centrifugal spinning machine. The steel mold should be placed on the spinning machine smoothly.

3.2 Put the mixed slurry into the mold and rotate in different directions under the motor driven.

3.3 In this process, the redundant water in the concrete is released by the force of centrifugal, and the concrete is dense and high strength. And then, the pole forms around the inner wall of the concrete pile mold.

4. 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.
