Description
Technical field
The utility model relates to a kind of glass fiber reinforced steel push pipe with sand, particularly a kind of outstanding glass fiber reinforced steel push pipe with sand that bears top power ability of having of reinforcing member and reinforced layer structure that has.
Background technique
In the municipal pipeline laying project, dual mode is generally arranged now: a kind of is open heavy excavation, ground can be excavated comprehensively, the mutual sheathed connection of pipe is placed down, again backfill gets final product again, the pipe that this mode needs is prefabricated, does not bear pressure or top power when connection and laying, and it is comparatively simple and convenient to construct; Another kind of mode is when being subjected to concrete environmental limit, such as building etc., and can not adopt heavy excavation mode tubing, can only dig working pit in advance, when the working pit operation, with one section one section on pipe underground certain depth location forward jacking pass, this operating environment needs the end of pipe to be provided with the push pipe part, the connection between the pipe is tightly connected by the collar.
Glass fiber reinforced steel push pipe with sand is as a kind of novel composite material pipeline, has light weight, high-strength, corrosion-resistant, characteristics such as the life-span is long, now is widely used in the pipe-jacking project.The glass fiber reinforced steel push pipe with sand of prior art generally is made up of tube head, pipe shaft and pipe tail, and wherein tube head, pipe tail connect by the collar when construction, and pipe shaft adopts layer of fibers and silica sand or calcium carbonate layer structure, and tube head and pipe tail adopt fiber layer structure.In said structure, the layer of fibers of pipe shaft and silica sand or calcium carbonate layer structure are mainly used in the hoop rigidity that provides required, and reduce production costs, and the fiber layer structure that tube head and pipe tail adopt is mainly used in axial strength required when jacking is provided.
Because tube head and pipe tail are stressed very big in the construction jacking, so the tube head of prior art and pipe tail all adopt the fiber layer structure of resin matrix.For reaching tube head and the required wall thickness of pipe tail, the number of plies of fibre cloth is more, causes cost to increase.
In addition, the tube head of prior art glass fiber reinforced steel push pipe with sand, pipe tail outer surface are the layer of fibers of resin matrix, because of conventional machining process institute extremely, can not guarantee caliber size and surface smoothness, there are irrational matching gap in tube head, pipe tail during construction when being connected with sleeve pipe, make glass fiber reinforced steel push pipe with sand the relative changing of the relative positions of two pipe ends in jack-in process, may occur, sleeve pipe is tilted, cause the jacking resistance to increase sharply.The lighter causes sealing effect to lose efficacy, and weight person causes tube head, pipe tail to tear, and jacking construction pauses.
