Product Description

 

 

 

1.  Overview of the prestressed concrete pile:

 

Prestressed concrete pile is a kind of hollow cylinder concrete prefabricated components made by tensioning prestressed technology and centrifugal compaction. The main components of the prestressed concrete pile are cylindrical pile body, end plate and steel ferrule.

 

The pile is used widely. It can be used for the engineering fundamentals of platform pole foundation of industrial and civil constructions, railways, high ways and bridges, ports, wharfs, water conservancy, municipal administration, structures and large scale equipment.

 

2. Features of prestressed concrete pile:

 

(1) Reasonable product structure, complete varieties and specifications, wide selection for design.

 

There are different outer diameter from φ300~φ600mm of different wall thickness and type A~C piles. The design value of bearing capacity of pile is 1250~6000KN.

 

(2) The concrete of piles has high strength. The mixed mineral admixture and additive technology are used. And we can make sure the strength grade of concrete will greater than or equal to C80 because the scientific proportioning design is used.

 

(3)The bearing capacity of prestressed concrete pile is high and the bending performance of it is good. It adopts prestressed concrete steel bars, pre-tensioning method prestressed tension process. So it has strong crack resistance moment and ultimate bending moment. And the bearing capacity of prestressed concrete pile is 2~5 times higher than other species of concrete piles.

 

(4) Good adaptability to geological. Due to the high strength of concrete pile body, the prestressed concrete piles are dense resistant to play and it has strong penetrability. So it has strong adaptability of the change of rolling force layer geological conditions.

4. The stack, transportation and acceptance check

 

(1)The place where stack the prestressed concrete piles should be a solid flat. The supporting point of the sole timber in the bottom of the stacked piles should be on the same plane.

 

(2) During the transportation process of the concrete piles, we should use some reliable anti roll and skid resistance measures.

 

(3) The acceptance check of concrete piles should according to the stipulations in the products standard—GB13476.

1. Overview of Heavy Concrete Spun Pile Spinning 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.

Centrifugal spinning machine for prestressed spun concrete pile is operated by remote-controlled continuously variable motor. It runs smoothly and has a variable-speed range. So the production of concrete piles are good of quality.

The base of the machine is welded in box-type structure, sturdiness and durability. The bearings are well sealed and reliable, long service. Random electric control equipment is complete and easy to operate.

 

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)   Spun pile spinning machine operates together with Pre-stressed concrete pile steel mold.

 

4)   Under the motor-driven, the slurry is divided into two-tier under the action of centrifugal force.

 

5)   The heavier solids deposited on the inner wall to form sediment layer, while the lighter liquid is separated from the formation of the inner fluid layer.

 

6)  The Sediment is released after dehydration, while the fluid is released.

 

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) Crack resistance can increase by about 3~5 times.

 

(3) Rigidity increases 1~3 times.

 

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

 

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

 

(6) Protect the environment on which human beings depend on for existence, and reduce the deforestation.

Concrete pile steel mold

 

 

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.
