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.
Summary of the invention:
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, and the internal flow resistance is little, the spun casting fibre reinforced composites push pipe that outside surface friction drag is little.
For achieving the above object, spun casting fibre reinforced composites push pipe of the present utility model comprises pipe shaft and the end that is connected that is arranged on described pipe shaft two ends, and wherein 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 bayonet joint 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.
Adopted in the described connection end that is provided with described injected hole seal ring be wedge type cross section rubber seal, and connect the hydro-expansive rubber seal ring that elliptic cross-section is adopted in 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. spun casting fibre reinforced composites push pipe joint adopts " F " type joint, and 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.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is that the pipeline configuration of spun casting fibre reinforced composites push pipe of the present utility model partly cuts open schematic representation;
Fig. 2 is the sectional view that the left side connects the amplification of end among Fig. 1;
Fig. 3 is the sectional view that the right side connects the amplification of end among Fig. 1;
Fig. 4 is a spun casting fibre reinforced composites push pipe installation diagram of the present utility model.
Embodiment
Referring to Fig. 1, spun casting fibre reinforced composites push pipe of the present utility model, comprise pipe shaft 1 and the end that is connected that is arranged on described pipe shaft 1 two ends, the structure of pipe shaft 1 is respectively from inside to outside: be the inside liner, glass fibre of matrix with the resin as the inside winding layer of reinforcing material, be the quartz mortar layer, glass fibre of filler outside winding layer and the outer protection layer as reinforcing material; Pipe shaft 1 two ends are provided with the connection end that is formed by pure layer of fibers coiling, and wherein Zuo Ce connection end is provided with three injected holes 8.Referring to Fig. 2, wherein shown a described injected hole 8.
Referring to Fig. 2 and Fig. 3, on each described connection end at described pipe shaft 1 two ends, along being respectively equipped with seal groove 2 and 3 on the circumferential surface of described connection end.
In work progress, be accompanied by the push pipe quilt along the direction jacking shown in the arrow among Fig. 1, by described injected hole 8 slurry bodies of side direction in the described push pipe, described slurry is overflowed outside described injected hole 8, form the lubricating layer between described pipe shaft 1 outer circumferential face and the soil, can reduce the surface friction drag of pipeline outer wall and soil thus greatly, realize the jacking distance one time, the characteristics that active well quantity is few, operating expenses is low than other tubing.
