Description
Technical field
The present invention relates to glass reinforced plastic sand pipe, particularly a kind of glass reinforced plastic sand pipe and manufacture method with axial direction fibre, and, can realize the convenient construction of under ground piping with the push pipe that this kind glass reinforced plastic sand pipe is made, and reduced cost.
Background technique
In the municipal pipeline laying project, dual mode is generally arranged now: a kind of is open type heavy excavation mode, be about to ground and excavate comprehensively, the mutual sheathed connection of pipe is placed down, auxilliary more upward earth is filled and led up and is got final product, the pipe that this mode needs is prefabricated, do not bear pressure or top power in connection and the process of deployment, it is comparatively simple and convenient to construct, still, engineering work load is bigger, causes the inconvenience of road traffic easily.Another kind of mode is that construction is subjected to concrete environmental constraint, such as building etc., and can not adopt heavy excavation mode tubing, can only dig working pit in advance, in the working pit operation, with one section one section on pipe in underground certain depth position 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.The pipeline of doing push pipe at first adopts the stainless steel push pipe, and the cost of this pipe is too high, does not have practical value; For the also requirement of proof strength that reduces cost, adopt Glass Steel Tube to do push pipe, but still cost was higher afterwards, promotion effect is slow; Now glass reinforced plastic sand pipe that adopt, cost reduces greatly more.
In the prior art, the reinforced plastic glass fibre layer is generally by three kinds of method coilings: a kind of is that reinforced plastic glass fibre intersects coiling repeatedly, the tubing that this mode turns to, and the axial force in the time of can bearing jacking can be used as push pipe; A kind of is the reinforced plastic glass fibre of hoop coiling, and the tubing that this mode turns to can not be done push pipe; Another is that reinforced plastic glass fibre is smashed, and adds resin and stirs, and pours into the tubing that die forming is made, and it is also relatively little that it bears axial intensity of force.
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 tube head and pipe tail adopt fiber layer structure to be mainly used in axial strength required when satisfying jacking.
Because glass fiber reinforced steel push pipe with sand tube head when the construction jacking is stressed very big with the pipe tail, so the tube head of prior art and pipe tail all adopt reinforced plastic glass fibre layer structure, for reaching tube head and the required wall thickness of pipe tail, the number of plies of fibre cloth is more, cause cost to increase, promoting the use of of glass fiber reinforced steel push pipe with sand caused certain influence.
Summary of the invention
Technical problem to be solved of the present invention is to provide a kind of glass reinforced plastic sand pipe and manufacture method with shaft orientation reinforcing rib at the deficiency that axially intensity is low, cost is high in the prior art, has higher axial strength, and can reduce cost.

In the technique scheme, described reinforced plastic glass fibre layer and burning into sand layer are taked the setting of multilayer stacked system.
In the technique scheme, described glass reinforcing rib takes to encircle the setting that evenly distributes of all modes.
In the technique scheme, go back hoop in the described reinforced plastic glass fibre layer and be provided with glass fibre.
The present invention also provides a kind of glass fiber reinforced steel push pipe with sand with shaft orientation reinforcing rib, comprises tube head, pipe shaft and pipe tail, and described pipe shaft was made of reinforced plastic glass fibre layer and burning into sand stacked adding; Described tube head, pipe tail are made of the reinforced plastic glass fibre layer, or are made of reinforced plastic glass fibre layer and burning into sand stacked adding; Be provided with axial reinforced plastic glass fibre in the described reinforced plastic glass fibre layer.
In the technique scheme, described tube head, pipe tail outer wall are provided with concave station, and tube head, pipe tail connect by the collar that is arranged on the described concave station.
In the technique scheme, described tube head and the thin burning into sand layer of pipe tail are not higher than the concave surface of described concave station.
In the technique scheme, the total thickness of described tube head and pipe tail burning into sand layer is less than the total thickness of the burning into sand layer of described pipe shaft.
The present invention also provides a kind of manufacture method with glass reinforced plastic sand pipe of axial direction fibre, comprises the steps:
Step 1, a tubular die two end axles is connected on the running shaft;
The reinforced plastic glass fibre layer of glass reinforced plastic sand pipe of the present invention adopts the shaft orientation reinforcing rib mode, this shaft orientation reinforcing rib is that the fiber direction that is soaked with the reinforced plastic glass fibre of resin is laid along the axial direction of pipe, it is big relatively that it bears axial top power, adopt the burning into sand layer to reduce cost, also can reach the requirement of intensity simultaneously.
Below by drawings and Examples, technological scheme of the present invention is described in further detail.
