FRP pipe jacking
FRP pipe jacking is a kind of water supply and drainage field, the newly developed pipeline products, can not dig the ground in the case of underground pipeline construction to complete the installation, it can directly through the roads, railways, rivers, ground buildings, due to Its own has a good corrosion resistance, light weight, smooth inner wall, large flow, good adaptability of geological conditions and other characteristics, therefore, become large and medium-sized city pipeline project in the preferred pipeline material.
Features of FRP Pipe JackingLight weight (for the concrete pipe 1/10), the ground requirements are low, the lifting, the next pipe equipment requirements are low, easy construction.
Due to small settlement, the top force and other reasons, easy to rectify the pipeline.
Smooth wall, large flow, in the flow to determine, available smaller diameter, can reduce the overall cost of the project.
Smooth appearance, the top force is small, the cohesion of the soil on the role of fiberglass pipe jacking is minimal, there is no pipe, dead pipe phenomenon, a single long jacking length, the requirements of the equipment into the low.
Pipe between the use of embedded steel ring connection positioning method, the top of the combination of glass fiber reinforced plastic mouth sealed, two tubes after docking.
Water sealing effect. The pipe at both ends of the car out of a platform, so that the steel ring sets of pipe end after the outer diameter of the steel ring and the pipe outside the same diameter
The Steel ring from the positioning role, and increase the ability of some anti-uneven settlement.
Resin mouth seal, two tube docking after the sealing effect. The pipe at both ends of the car out of a platform, so that the steel ring sets of pipe end after the outer diameter of the steel ring and the pipe outside the same diameter. Steel ring from the positioning role, and increase the ability of some anti-uneven settlement.
FRP pipe jacking Features:1, the pipeline laying without ditching, construction progress quickly;
2, the final process of correction is easy, jacking distance is long;
3, the appearance of smooth, light weight, the top into the resistance is small; FRP duct surface is not easy to deposit, will not produce tube lock phenomenon;
4, FRP pipe wall is very smooth, good hydraulic fluid characteristics;
5, with excellent waterproof, anti-seepage, chemical resistance;
6, can be long-term operation under high temperature conditions, and maintain good mechanical properties;
7, the product application of a wide range of ambient temperature, generally -40 ~ 70 ℃, FRP duct can resist long-term exposure to sunlight;
8, with excellent wear resistance, the transmission medium will not damage the inner wall of the pipeline;
9, FRP pipe thermal conductivity is low, good insulation properties;
10, no toxic, no secondary pollution;
11, small proportion, light weight, easy loading and unloading, easy to install;
12, FRP pipe design safety factor, long life, to ensure that the service life of 50 years;
13, FRP duct operation and maintenance costs low, corrosion resistance superior, without any maintenance;
