Brief Introduction for GRP mortar Jacking pipe

The GRP mortar Jacking pipe with brand of “golden wave” produced by Yongchang Composites Co.,Ltd. which is a kind of pipe that use resin as matrix, sand as the filler, glass as the reinforcement, both ends of the pipe are pure glass fiber-resin, adopt mechanical winding process controlled by computer.

Good performance

Light weight (its weight is 1/10 of concrete pipe), which has a low request for the base, lifting, and the unloading machine, and easy construction.

It is easy to correct the departure of the pipe due to the cause of low sedimentation, and jacking force.

You can reduce the comprehensive cost on construction project because the pipe has a smooth inner surface, high flow capacity, under the condition of the flow capacity confirmed, you can choose the smaller diameter pipe.

The pipe has a smooth outer surface, which only needs a low jacking force, it is no effect to the pipe from the soil resistance, and it has a low request for the jacking equipment.

Connection way

Our company adopt “F” shape joint for connecting GRP mortar jacking pipe, which consist of pure GRP front and back end, steel ring, cuneate rubber sealed ring, water-expansion rubber sealed ring, hole of immiting water for reducing resistance, and the annular space of immiting water for reducing resistance.
