2. ambient influnence is little: jacking construction mainly carry out underground, and earth excavation is few except the excavation of working pit and receiving pit, thus very little to surrounding environment influence, also influence very little near structure (as original pipeline); And the fluting pipe laying is land operations entirely, and the people is many, and soil is many, and the environment around certainly will giving brings very big influence.
3. should be in special operation condition: or situation that soil property very soft very high when underground water level, adopt the fluting pipe laying just to be difficult to carry out, if pipeline river crossing, highway, railway or pipeline need be embedded under the building in addition, more this just cannot carry out the fluting pipe laying, and for above-mentioned all situations, jacking construction still can be implemented very easily.
Just because of pipe jacking construction technique has above advantage, the application of jacking construction more and more widely.
But in traditional concrete and steel pipe jacking construction, also also have many problem demanding prompt solutions, important have an easy countersunk head of subgrade, correction difficulty etc., these two kinds of tubing corrosion resistances are poor in addition, and application life, short the grade also restricted further developing of pipe jacking construction technique.
If but in push pipe, adopt glass fiber reinforced plastic sand-inclusion pipeline to overcome the above problems.
Glass fiber reinforced steel push pipe with sand as a kind of novel composite pipe, has advantages such as lightweight, high-strength, corrosion-resistant, life-span are long.Use it in the pipe-jacking project and compare, following characteristic advantage is arranged technically with traditional steel pipe push pipe, concrete ceiling coil:

2. barrier properties is relatively poor, and actual engineering shows: when place, pipeline place exists underground water higher, will be easy to generate seepage;
3. can not carry out the slip casting drag reduction, when the frictional resistance of soil is big, cause a jacking length to reduce.
4. renitent joint design is not arranged as yet, limited the application of glass fiber reinforced plastic push pipe in non-excavation pressure pipeline.
