Abstract
The invention discloses a reciprocating cross type wound glass fiber reinforced plastics mortar grouting jacking pipe, a pipe body wall of which comprises a lining layer, an internal winding layer, a rigid layer, an external winding layer and an outer protecting layer which are sequentially compounded from inside to outside, wherein two ends of a pipe body are provided with connecting ends, and one connecting end is provided with a grouting hole. The rigid layer is formed by compounding a resin matrix, fibers and quartz sand filler; the connecting ends are formed by winding resin matrixes, fibers and one-way fiber fabrics or compounding the resin matrixes, the fibers and the one-way fiber fabrics and quartz sand slurry layers; the peripheral surface of each connecting end is provided with a sealing groove, and the connecting ends of two pipes are connected through steel lantern rings and sealing rings in a sealing manner, wherein the connecting manner is a socket and spigot joint connection manner. The reciprocating cross type wound glass fiber reinforced plastics mortar grouting jacking pipe has the advantages of high mechanical strength, simple operation, convenience and rapidness for construction and no need of special devices. The lining layer of the reciprocating cross type wound glass fiber reinforced plastics mortar grouting jacking pipe plays a role of preventing corrosion and leakage, the internal winding layer, the rigid layer and the outer winding layer effectively ensure strength and rigidity of the pipes; and the outer protecting layer ensures that ageing resistance, corrosion resistance and function of reducing friction resistance of the pipes and soil are greatly enhanced.
Description
Technical field
The present invention relates to a kind of pipeline, specifically is a kind of reciprocal staggered form fw frp burning into sand slip casting 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; Easy ageing, poor corrosion resistance; The frictional resistance of pipeline surfaces externally and internally and soil is big, occurs embracing pipe and dead pipe phenomenon easily; The sealing of link is poor, is easy to generate seepage.
Summary of the invention
The object of the invention just provides a kind of reciprocal staggered form fw frp burning into sand slip casting push pipe; The body heaviness, lifting and the following pipe difficulty that exist with the solution prior art are big; Easy ageing and poor corrosion resistance; Pipe and dead pipe phenomenon appear easily embracing, the sealing difference of link and the leakage problems that is prone to produce.
Technical scheme of the present invention 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 said body is made up of resin matrix, glass fiber and quartz sand filler mixing; The link at described body two ends is made up of resin matrix, fiber and unidirectional fabric coiling.
The stiffness layer of said body is made up of resin matrix, glass 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 through 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 invention 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 present invention is distributed in maximum internal layer and the skin of stress 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 confirmed, 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 an armful pipe, extremely manages phenomenon, and single jacking length is long, and is low to the jacking equipment requirements;
5, its link good seal performance, bonding strength is high.

The specific embodiment
Referring to Fig. 1～Fig. 5, the present invention includes body 1, this body 1 constitutes 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 are compound; Two ends at body 1 are provided with link; A link (left end, the end that advances when promptly heading into) is provided with injected hole 8, its purposes therein: when construction from managing the introversive excessive slurry that goes out; The external side of lubrication management; Can reduce the frictional resistance of pipeline outer wall and soil greatly, realize the jacking distance one time, the characteristics that active well quantity is few, operating expenses is low than other tubing.Arrow among Fig. 1 is represented pipeline jacking direction in use.
The stiffness layer of said body 1 is made up of resin matrix, fiber and quartz sand filler mixing; The link at described body 1 two ends is made up 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 invention interconnects; Be tightly connected through 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, in the seal groove 3 in left side, is provided with the hydro-expansive rubber sealing ring 4 of elliptic cross-section; 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 mechanical strength is high, and simple to operate, 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.
