Abstract
The utility model provides a kind of composite material for being sealed outside pipeline in-situ immobilization hose, and the composite material sealed outside the hose includes the theca externa, enhancement layer and theca interna being arranged in order；The enhancement layer is polyester knitting object, and the interior theca externa is polyurethane elastomer material (PU), ethylene-vinyl acetate copolymeric material (EVA) or polythene material (PE), and film layer is compound with enhancement layer by way of curtain coating.Composite material combines the flexible nature of film layer and the strength characteristics of knitted fabric, in carrying out capping processes to hose, by theca interna sweat soldering on the outside of hose, seam is beautiful, good airproof performance, and intensity is high, the leakproofness of hose is effectively ensured, it is ensured that the safety of pipeline in-situ immobilization process.
Description
Technical field
The utility model belongs to field of compound material more particularly to a kind of is answered for what is sealed outside pipeline in-situ immobilization hose
Condensation material.
Background technology
By the end of the year 2015, municipal drainage pipe duct length total amount in China's reaches 540,000 km, and is increased with annual 6% rate
Long, since the service life of pipeline is usually 30-50, China is laid with pipeline of the remote past and reaches the length of service in succession.According to
Statistics, the municipal drainage length of tube that China is laid with before the eighties is 2.2 ten thousand km, and occurs disease conditions in succession, such as structural
Defect and functional defect, these disease incidences cause drainage pipeline that cannot play due effect, and sewage runs, emits, leaks, and block
Traffic, rainwater cannot drain in time, and surface collapse is caused when serious, is made troubles to urban construction and people's lives, or even danger
And the security of the lives and property of people.
Reparation for disease pipeline, traditionally using the method for pipe laying again after excavating, this greatly destroys city
Traffic environment and seriously affect people’s lives with work.No-dig technique method only needs to construct at pipe well, has construction period
It is short, the advantages of not influencing traffic.Wherein, in-situ solidifying method is applied widely, and convenient construction is had excellent performance, and by industry
Favor, this method will be soaked on the composite soft tube material liner to inner wall of the pipe to be repaired of resin using hydraulic pressure or air pressure,
Make resin solidification by the method for heating or radiating, form new pipeline inside original disease pipeline, restores the original work(of pipeline
Energy.
In recent years, as technology maturation and reliability increase, China's pipeline trenchless technology is quickly grown, and hose is preliminary
Realize production domesticization.Seam is the key link of hose industrialization, determines the success or failure of work progress.《Urban drainage pipeline is non-
Trenchless rehabilitation renewal project technical regulation》(CJJ/T 210-2014) is provided：The seam of each layer of multi-layer flexible pipe should be staggered, and seam connects
It scoops out securely.Theoretically the tensile strength of seam crossing should be consistent with main material, that is, is not less than 5MPa, and joint filler determines hose
Quality, a kind of highly desirable composite material can effectively solve the problem that seam problem of people.
Utility model content
Problem to be solved in the utility model is against the above deficiency, to provide a kind of for pipeline in-situ immobilization hose covering
The composite material of mouth.
In order to solve the above technical problems, the technical solution adopted in the utility model is：One kind is soft for pipeline in-situ immobilization
The outer composite material sealed of pipe, it is characterised in that：The composite material sealed outside the hose includes the theca externa being arranged in order, adds
Strong layer and theca interna；The theca externa is polyurethane elastomer material (PU) or polythene material (PE), and thickness 2-4mm is wide
Degree is 3-5cm；The enhancement layer is polyester knitting object, and width is identical as base, weight 80-200g/m2；The theca interna is
Polyurethane elastomer material (PU) or polythene material (PE), width is identical as theca externa, thickness 0.1-0.2mm；It is described outer
Film layer and theca interna are distinguished by way of curtain coating with enhancement layer compound.
The utility model has the advantages and positive effects of：Composite material combines the sealing characteristics and needle of interior theca externa
The strength characteristics of fabric, outer membrane thickness play the role of sealing antiseepage, and theca interna is thin, the material as sweat soldering.Three layers of material
Material is combined with each other by way of curtain coating during lamination, and composite material is formed.Sealing treatment process is being carried out to hose
In, by theca interna sweat soldering on the outside of hose, seam is beautiful, and bonding is secured, and good airproof performance can effectively ensure that the sealing of hose
Property, it is ensured that the safety of pipeline in-situ immobilization process.

Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to specific embodiment of the utility model.
A kind of composite material for being sealed outside pipeline in-situ immobilization hose, it is characterised in that：It is sealed outside the hose
Composite material includes the theca externa 1, enhancement layer 2 and theca interna 3 being arranged in order；The theca externa 1 is polyurethane elastomer material
(PU) or polythene material (PE), thickness 2-4mm, width 3-5cm；The enhancement layer 2 be polyester knitting object, width with
Base is identical, weight 80-200g/m2；The theca interna 3 be polyurethane elastomer material (PU) or polythene material (PE),
Width is identical as theca externa, thickness 0.1-0.2mm；The theca externa 1 and theca interna 3 are by way of curtain coating and enhancement layer
It is compound respectively.
A kind of method that pipeline in-situ immobilization hose seals outside, the method for the outer sealing is by the theca interna of composite material
3 fusing or part melt, carried out with hose outer side seam region 6 it is be bonded, after cooling, with hose outer layer antiseepage film 4 securely tie
It closes, is integrally formed, hot melting temperature is identical as material softening or fusion temperature.
The section Example of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should all still belong within the patent covering scope of the utility model.
