Abstract
Disclosed is a reinforced thermosetting resin sanding including jacking pipe with fibre winding. The pipe wall of the utility model comprises an inner lining layer, an inner winding layer, a rigid layer, an outer winding layer and an outer protective layer, which are made into a composite orderly from the inside to the outside. Both ends of the pipe body are provided with connecting ends, and one of the connecting ends is provided with a grouting hole. The rigid layer is mixedly composed of resin matrixes, fabrics and quartz sand filling; the connecting ends are windingly composed of resin matrixes, fabrics and unidirectional fabrics, or compositely composed of resin matrixes, fabrics, unidirectional fabrics and quartz sand mortar beds. The peripheral surface of each connecting end is provided with a seal groove; the connecting ends of two pipes are sealedly connected by a steel lantern ring and a seal ring. The connecting mode of bayonet connection has high mechanical strengths, and is simple to operate, convenient and fast to construct, and no special equipment is required. The inner liner layer of the utility model plays roles in antisepsis and antiseepage, and the inner winding layer, the rigid layer and the outer winding layer effectively guarantee the strength and rigidity of the pipe, and the outer protective layer greatly enhances the roles of antiaging, preventing corrosion, and reducing the friction and resistance between the pipe and the soil.
Description
Technical field
The utility model relates to a kind of pipeline, specifically is that a kind of fiber twines and strengthens thermosetting resin sand inclusion slip casting formula push pipe, mainly is used at the tubing of giving, using when unconditionally carrying out ground excavation and various complex geological condition in the draining field.
Background technology
Existing this type of push pipe generally adopts steel pipe or concrete duct.Its shortcoming is heavy, is not easy lifting and following pipe; Aging easily, poor corrosion resistance; The frictional resistance of pipeline surfaces externally and internally and soil is big, occurs holding tube and dead pipe phenomenon easily; The sealing of link is poor, is easy to generate seepage.
Summary of the invention
The purpose of this utility model just provides a kind of fiber and twines enhancing thermosetting resin sand inclusion slip casting formula push pipe, the body heaviness, lifting and the following pipe difficulty that exist with the solution prior art are big, wear out easily and poor corrosion resistance, holding tube and dead pipe phenomenon appear easily, the sealing difference of link and easily produce leakage problems.
The technical solution of the utility model is: comprise body; described tube body wall comprises compound successively from inside to outside inner liner, inner winding layer, stiffness layer, outside winding layer and outer protection layer; be provided with link at the body two ends, a link is provided with injected hole therein.
The stiffness layer of described body is made of resin matrix, fiber and quartz sand filler mixing; The link at described body two ends is made of resin matrix, fiber and unidirectional fabric coiling.
The stiffness layer of described body is made of resin matrix, fiber and quartz sand filler mixing; The link at described body two ends is by resin matrix, fiber and unidirectional fabric and the quartz mortar layer is compound constitutes.
Side face at described each link is equipped with seal groove, and a link is provided with injected hole therein; Be tightly connected by steel collar and sealing ring between the link of two pipelines, and adopt bayonet joint, in the seal groove of two links, respectively be provided with sealing ring.
One of described sealing ring is the hydro-expansive rubber sealing ring of elliptic cross-section, and another root is a wedge type cross section rubber seal.
Anticorrosion, antiseepage effect that liner of the present utility model plays, inner winding layer, stiffness layer and outside winding layer have guaranteed the strength and stiffness of pipeline effectively, external protection makes, and effect anti-aging, corrosion-resistant, that reduce the frictional resistance of pipeline and soil strengthens 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 frame mode of very economical rationality.Following advantage is specifically arranged:
1, in light weight: as to be 1/10 of concrete duct, 1/4 of steel pipe.Since in light weight, the generation of the differential settlement phenomenon of whole piece pipeline avoided, adding that top power requires reasons such as little, pipeline is rectified a deviation than being easier to;
2, to foundation situation and lifting and down the pipe facility require low, convenient and quick construction;
3, inner wall smooth, flow is big, under the situation that flow is determined, can select the pipeline than little 1～2 the caliber grade of other tubing for use, and expense can reduce greatly;
4, smooth in appearance, the cohesive strength of soil is very little to the effect that this pipe produces, and is not easy to produce holding tube, extremely manages phenomenon, and single jacking length is long, requires low to jacking equipment;
5, its link good seal performance, the bonding strength height.

The specific embodiment
Referring to Fig. 1～Fig. 5; the utility model comprises body 1; this body 1 is by compound successively from inside to outside inner liner 11; inner winding layer 12; stiffness layer 13; outside winding layer and 14; outer protection layer 15 compound formation; two ends at body 1 are provided with link; link (left end therein; the end that advances when promptly heading into) is provided with injected hole 8; its purposes: when construction; by the slurry pipeline that is connected with this hole by outwards extruding slurry in the pipe; the external side of lubrication management; can reduce the frictional resistance of pipeline outer wall and soil greatly, realize the jacking distance one time, active well quantity is few; the characteristics that operating expenses is low than other tubing.Arrow among Fig. 1 is represented pipeline jacking direction in use.
The stiffness layer of described body 1 is made of resin matrix, fiber and quartz sand filler mixing; The link at described body 1 two ends is made of resin matrix, fiber and unidirectional fabric coiling, or by resin matrix, fiber and unidirectional fabric and the quartz mortar layer is compound constitutes.Side face at each link is equipped with seal groove 2 and 3.
Referring to Fig. 4, when body 1 of the present utility model interconnects, be tightly connected by steel collar 6 and sealing ring 4 and 5 between the link of two pipelines, steel collar 6 is enclosed within two link outsides and adopts the sealing ring bayonet joint, is provided with the hydro-expansive rubber sealing ring 4 of elliptic cross-section in the seal groove 3 in left side; In the seal groove 2 on right side, be provided with wedge type cross section rubber seal 5.This is connected to spigot-and-socket and is tightly connected, and the sealing performance of link is more more reliable than other connected mode, and the mechanical strength height, and is simple to operate, and convenient and quick construction need not special installation and both can construct.Between the side face of injected hole 8 outer ends of the inboard of steel collar 6 and right side link, form the ring-like space 7 of slip casting drag reduction.
