concrete culvert pipe machine for draining

Overview of concrete pipe steel mould 

Concrete  pipe mould is a drainage steel mold with rigid joint, when running on the centrifugal spinning machine , it rotates rely on the friction force made by the roller and steel mold. Under the action of centrifugal force ,the concrete will be distributed to the inner of mold equally to form reinforced concrete pipe, it is a simple but useful concrete machine.

Production process:
Adjusting the vibration system to the best station according to the size of concrete pipe and the vibration frequency of the raw material diameter. When putting materials , vibrate, on the effect of amplitude vibration , it need 1-5 minutes to form solid molding ,interval time is 1-5 seconds , it means demoulding automatically no matter how big the size is.After demoulding , the mold will be transfer to curing place by trolley , the concrete pipe machine will be used to produce the next one when the product put away.
When produce concrete pipes with different specification, it just needs a relevant mold to ensure the product same.
The machine can be installed underground, it has advantage of small voice, no pollution , safe and reliable.
Suspension roller concrete pipe machine apply to concrete pipes with small diameter, it has advantage of saving cost, high productivity.

1 Avoiding the mold fly away the machine in spinning process

1.1The angle between running laps and running wheels should be in the range of 90-110, if the angle less than 90, it is easy to fly away, if the angle more than 110, the running wheel will be in a bigger stress to make displacement , even stuck the mold.

1.2 If the shafts are not parallel,the mold maybe fly away from the machine.

1.3 If the running wheel or mold laps are not perfect circle, the mold also have the possible of flying away.

1.4If the gravity of mold is offset, it may sway to one direction when spinning , if it is in high speed, the mold will fly away.

1.5 if the height of shafts is not the same , or the running wheel size is not same, it will make the mold tilt to one side , when rotating in high speed, the mold will fly away.

2 Avoiding the machine move to one side

 Moving to one side is one reason of flying away, even if it does not make the mold fly away,it will damage the circle of the running wheel and running laps after a long time of moving to one side.It is necessary to solve this problem to avoid the accident.

3.The shafts have to be parallel and have a same height when installation.

4.The cement paste will flow to the bearing when the spinning machine working ,which makes the bearing wear or heated,so the sealing of bearing is important.

Working Principle

This machine uses the Roller to support the pipe mould, and produce the roller force to concrete in the mould.
When the roller rotate at a high speed, the concrete in the mould will spread in the inner wall of the pipe mould
and form a cement pipe with the centrifugal force, and when the mould with the inner concrete pass on the roller,
the concrete between the mould and the roller will be compacted solid to form a pipe.

(1) Short production Cycle: because of the good effect of the roller to compact the concrete, every pipe just need 3-5 minutes with high speed roller rotation.
(2) This Pipe machine uses the dry cast material, there will no waste cement mud, then it won’t pollute the environment.
(3) During the production, the noise is low, it is about 80-90 DB
(4) The Concrete Pipes are with high pressure load and with high production efficiency.

Different Machines with Different Package,  Plastic and Thick Paper,  Wooden Box or as the suctomer's request

      Ningjin County Shuangli Building Materials Machinery Factory was founded in 2005.The factory is located at the west of Ningjin County, on the 324 provincial highway.

LF Series Multi-function cement tube making machine is ideal equipment for the production of concrete tubes ,it is reasonable in design ,more reliable in running and more convenient in operating.

It completely meets the state standards of GB 11836-89, with river sands ,gravels stone chips or pulverized coal ash , slag, et, pulsing Some suitable quantity of cement as raw materials ,the machine can produce different kinds of tubes ,such as joint tubes socket tubes, etc ,with different diameter specifications from 150mm to 800mm,all the tubes produced by this machine are characterized by even wall thickness, smooth inner wall, good resistance to leaking .

High compression strength ,lower cost, excellent reliability in connecting ,convenience in construction and better efficiency in production ,and also ,the products ,can be given curing immediately after molding, these tubes can be widely used in the projects of agricultural irrigations ,water draining in cities.
