Application of CAD in RPM Pipe Design;

Low cost large stiffness FWRPM pipe is a pipe of composite material composite structure suitable for low cost,major diameter,large stiffness,high transport efficiency,resistant corrosion,technique require,etc.

Application of grit-mixed glass fiber plastic pipeline in reservoir dam;

By means of field test and analysis on the section of glass reinforced plastic mortar pipe (GRPMP), a concise empirical formula was obtained, which was suitable for the construction of slurry pressure balance type GRPMP by using jacking method.

At present, in the developed area of China, the using of glass reinforced plastic mortar pipe is growing.

The sand sandwiched GRP pipe is a new type of composite pipe in the seventies of last century.

Traditional sand sandwiched GRP pipes with large diameter require four courses of gasket at the socket end and it is difficult to make the casing.

In the sewage project of Nanzhou Road,a mechanical construction technology with equilibrium of slurry and soil was used for the construction of glass fibre reinforced plastic mortar pipe(FRMP) of the definite-length-winding for pipe jacking.
