The purpose of this utility model is to reach the effect erosion resistance, light quality and resistance reduction for said jack pipe. This utility model comprises pipe body and connection ends at said pipe body. The pipe structure takes resin and main material and quart sand as filling substance wound with fiber glass as reinforcement. The two ends of pipe body are composed with pure fiber layer and semi-pure fiber, semi-quartz sand layer; a plurality of injection holes are set at one connection end, especially used for the situation improper for surface excavation soil course.
Description
Technical field
The utility model relate to a kind ofly give, widely used pipeline in the draining field, mainly apply under the condition that can not excavate surface layer soil, directly highway crossing, railway, rivers, above ground structure and various underground structure are to be applicable to that the double sealing fiber under the various severe environmental conditions twines enhancing thermosetting resin sand inclusion slip casting formula push pipe.
Background technique
Existing push pipe material is mainly: steel push pipe, reinforced concrete push pipe.The steel push pipe in use exists corrosion-resistant, the shortcoming that working life is short; The reinforced concrete push pipe in use, because the tube wall quality is big, the shortcoming of easily fouling, the ability of pressing in bearing, also must inside and outside carry out preservative treatment, thereby increased surperficial surface friction drag, so the top power that needs in jack-in process is very big, and one time jacking length is very limited, and the utmost point is not suitable for passing through as river, river, large size ground building and various underground large size structure etc.
This shows existing push pipe material corrosion-resistant, big, the easily fouling of weight.Also there are problems such as easy-to-rust breaking releasing, working life weak point, difficult jacking in the tradition Placement.
The technology contents of model utility
For this reason, technical problem to be solved in the utility model is to propose a kind of corrosion-resistant, light weight, drag-reduction effect is obvious, easily jacking, a jacking distance, inside and outside wall is smooth, the internal flow resistance is little, and the double sealing fiber that outside surface friction drag is little twines and strengthens thermosetting resin sand inclusion slip casting formula push pipe.
For realizing above-mentioned model utility purpose, double sealing fiber of the present utility model twines and strengthens thermosetting resin sand inclusion slip casting formula push pipe, comprise pipe shaft and the end that is connected that is arranged on described pipe shaft two ends, it is characterized in that: the pipe shaft structure is by being matrix with the resin, silica sand is filler, and it is that reinforcing material constitutes that glass fibre twines yarn; The pipe shaft two ends are provided with the connection end of being made up of pure layer of fibers or half pure fiber half silica sand screed, and one of them connects the end and is provided with several injected holes.
Wherein, can be equipped with seal groove at the side face of described connection end.
In addition, joint at two pipelines, be tightly connected by steel collar and the seal ring that is arranged in the described seal groove, and adopt " F " type joint to be connected between described connection end and the described steel collar, in the seal groove at two ends, respectively be provided with seal ring, between the inner peripheral surface of described steel collar and the described outer circumferential face that is connected the end that is provided with described injected hole, form a ring-like space of slip casting drag reduction that is communicated with described injected hole.
The seal ring that is adopted in the described connection end that is provided with described injected hole is a wedge type cross section rubber seal, and connects the hydro-expansive rubber seal ring that elliptic cross-section is adopted in the end at another.
Technique scheme of the present utility model has the following advantages compared to existing technology: liner plays anticorrosion, antiseepage effect, and construction layer has effectively ensured the strength and stiffness of pipeline; The existence of external protection strengthens anti-aging, corrosion-resistant, as to reduce the surface friction drag of pipeline and soil effect greatly.The utility model is distributed in the internal layer and the skin of stress maximum by bending to the big fiber winding layer of intensity, is the mode of structure of very economical rationality.In addition:
1. in light weight (be concrete duct 1/10, steel pipe 1/4), to foundation situation and lifting, to manage the facility requirement down low, easy construction, quick.
2. owing in light weight, avoided the generation of the uneven settlement phenomenon of whole piece pipeline, added that top power requires reasons such as little, pipeline is rectified a deviation than being easier to.
3. inner wall smooth, flow is big, under the situation that flow is determined, can select the pipeline than little 1 to 2 the caliber grade of other tubing for use, and expense can reduce greatly.
4. smooth in appearance, the cohesive force of soil is minimum to the effect that this pipeline produces, and does not have holding tube, extremely manages phenomenon, and single jacking length is long, and is low to the requirement of jacking equipment.
5. the double sealing fiber twines and strengthens thermosetting resin sand inclusion slip casting formula push pipe joint employing " F " type joint, by front and back pipe end, steel collar, wedge type rubber seal, hydro-expansive rubber seal ring, be used for the drag reduction hole of slip casting, the ring-like headspace of slip casting drag reduction is formed.
