Description
Technical field
The present invention 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.
Summary of the invention
The objective of the invention is provides a kind of glass fiber reinforced steel push pipe with sand at the defective of prior art, has advantages such as cost is low, intensity is high, easy processing, and can guarantee the reasonable clearance that pipeline cooperates.
In order to achieve the above object, the invention provides a kind of glass fiber reinforced steel push pipe with sand, comprise tube head, pipe shaft and pipe tail, described tube head, pipe tail outer wall are provided with concave station, tube head, pipe tail connect by the collar that is arranged on the described concave station, described tube head, pipe shaft and pipe tail are matrix with the resin, with the glass fibre is layers of reinforcement, with silica sand or calcium carbonate is packing layer, described tube head and pipe tail end are provided with reinforcing member, described reinforcing member is an annular end cap, and annular end cap is fastened on tube head and pipe tail end, covers the cross section of tube head and pipe tail end; The tube wall of described tube head and pipe tail also is provided with the reinforced layer of metal or non-metallic material.
In technique scheme, the burning into sand layer total thickness of described tube head, pipe tail pipe wall is less than the burning into sand layer total thickness of pipe shaft tube wall.Described reinforced layer can be arranged in the tube wall for stiffener or stiffening ring.Described reinforced layer is a fabricated metals, can be arranged in the tube wall of tube head and pipe tail, can also be arranged on the outer surface of tube head and pipe tail.
In technique scheme, described annular end cap can also be that inner side surface is provided with the protruding part that inserts in the tube wall.
The invention provides a kind of glass fiber reinforced steel push pipe with sand of new structure; improved glass fiber reinforced steel push pipe with sand and born top power ability by reinforcing member being set at tube head and pipe tail; reinforcing member has played the effect of protection tube head and pipe tail well, and the jacking pressure that simultaneously it is born passes equably.Because the effect of reinforcing member is guaranteeing under body integral rigidity, the intensity prerequisite the present invention, can in the tube wall of tube head and pipe tail the burning into sand layer be set, and has reduced the cost of glass fiber reinforced steel push pipe with sand to greatest extent.
Preferred version of the present invention provides a kind of glass fiber reinforced steel push pipe with sand with reinforced layer, reinforced layer can be provided with one or more layers according to the force-bearing situation of construction jacking, can only be arranged in the tube wall of tube head and pipe tail, also can be arranged on the interior tube structure that forms of tube wall of whole pipe continuously, further improve glass fiber reinforced steel push pipe with sand and bear top power ability.Simultaneously, preferred version of the present invention also provides a kind of glass fiber reinforced steel push pipe with sand with outer reinforced layer, because the outer surface of tube head and pipe tail is a metal, can accurately guarantee the external diameter precision of tube head and pipe tail, when being connected cooperation with sleeve pipe, have reasonable supporting clearance, the pipe end changing of the relative positions can not occur in the jack-in process, significantly reduced the jacking resistance.
Below in conjunction with accompanying drawing the present invention is done explanation in further detail.
