Abstract
This utility model relates to a sand-sandwiched fiberglass jack pipe including pipe head, pipe body and pipe tail. Said pipe body takes resin a base and fiberglass as a reinforcement course, quartz sand or calcium carbonate as a filling course; while the pipe head and pipe tail takes resin as base and fiberglass as reinforcement course. Said pipe head and /or the outside of the pipe tail accept concave stub composing with metal course. This utility model solves the problem that prior sand-sandwiched fiberglass fails to resist more axial force and bending stress and poor sealing between jack pipes; this utility model increase one-time jack pipe length and cut down damage of jack pipes with improvement of seal between jack pipes.
Description
Technical field
The utility model relates to a kind of glass fiber reinforced steel push pipe with sand, the glass fiber reinforced steel push pipe with sand with metal layer concave station that particularly a kind of municipal pipeline engineering is used.
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 the pipe tail of resin matrix, 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.
The layer of fibers of glass fiber reinforced steel push pipe with sand generally by the glass fiber cloth that is soaked with resin or cellosilk from level to level coiling form, since the layer with layer between by resin be the matrix gluing together, under loading, interlayer exists the trend of layering, can not bear bigger axial jacking intensity, limit single jacking length.In practice of construction, because glass fiber reinforced steel push pipe with sand also can bear certain flexural stress, when single jacking length is long, top power skewness or when rectifying a deviation operation, bigger flexural stress can cause glass fiber reinforced steel push pipe with sand damage and even destruction situation to occur, influence construction quality and progress, even cause that the pipe-jacking project section scraps accident.
In addition; owing to can not guarantee in the push pipe production process that the outside dimension of tube head and pipe tail is in full accord; big slit appears in regular meeting between the outer wall of the collar and tube head pipe tail; even the seal ring that adopts seals, what still be difficult to avoid fully liquid in the push pipe passes through the slit to the push pipe external leakage.
The model utility content
One of the purpose of this utility model be solve that existing glass fiber reinforced steel push pipe with sand exists can not bear the problem of larger axis to top power and flexural stress, to increase single jacking length and to reduce the generation of push pipe damaged condition in the construction.
Another purpose of the present utility model is to solve the poor sealing that existing glass fiber reinforced steel push pipe with sand exists, and occurs the problem of the interior liquid of push pipe to the push pipe external leakage easily.
In order to achieve the above object, the utility model provides a kind of glass fiber reinforced steel push pipe with sand, comprise tube head, pipe shaft and pipe tail, pipe shaft is matrix with the resin, with the glass fibre is layers of reinforcement, is packing layer with silica sand or calcium carbonate, and tube head and pipe tail are matrix with the resin, with the glass fibre is layers of reinforcement, and the described tube head and/or the pipe tail outside have the concave station that is made of metal layer.
In order to strengthen the axial jacking intensity of push pipe, above-mentioned metal layer can extend to the pipe shaft part or extend to the pipe tail from tube head always from described tube head and/or pipe tail.Described metal layer is a sheet metal, preferably is provided with the sheet metal of a plurality of through holes.Internal surface at described sheet metal is provided with plucking or teeth groove structure, forms rough and uneven in surface surface, with the adhesive strength of increase and resin and glass fibre.In order further to increase the sealing that connects between push pipe, be provided with the one or more grooves that are used for sheathed rubber seal at the concave station of described tube head and/or pipe tail.Described rubber seal can be wedge type rubber seal or ellipse hydro-expansive rubber seal ring.In addition, in the concave station of described tube head and/or pipe tail, also be provided with the one or more injected holes that are used for the slip casting drag reduction.
Advantage of the present utility model is:
1, by metal layer being set, can increase jacking intensity greatly, be suitable for long-distance pipe jacking, in engineering, can significantly reduce the number of working pit at tube head and/or pipe tail;
2 compare with the reinforced plastic glass fibre layer, and the external diameter of tube head and pipe tail metal layer is consistent easily in the production process, and its outer surface also is easy to form flat surface, and the end is connected to be convenient to form closely with the cover interannular, and piping erection makes things convenient for, good airproof performance.
3, improve the ability that push pipe bears flexural stress, reduced the possibility of the generation of push pipe damaged condition in the construction, and be easy to correction.
Below in conjunction with accompanying drawing the utility model is done explanation in further detail.
