Abstract
Strengthen cured in place liner pipe the invention discloses a kind of seamless double-layer, it is characterized in that, described seamless double-layer enhancing cured in place liner pipe includes a macromolecule layer, one first reinforcement fibrous layers, one first adhesive layer, one second reinforcement fibrous layers and one second adhesive layer successively from the inside to the outside, and the second described adhesive layer is mutually be bonded with a pipeline.In pipeline non-excavation rehabilitation, only two construction holes need to be excavated during construction being repaired pipe ends, the internal lining pipe is converted into U-shaped and is drawn in pipeline, the internal lining pipe is extended using external Thermocuring equipment, so that the first adhesive layer and the second adhesive layer are simultaneously to exosmosis, so that internal lining pipe is securely fixed in the pipeline of breakage, realize that pipeline is repaired.Seamless double-layer enhancing cured in place liner tubular construction is compact, and easy construction, effect is substantially, practical.
Description
Technical field
The present invention relates to a kind of pipeline, more precisely, being a kind of seamless double-layer enhancing cured in place liner pipe.
Background technology
In city or industrial piping system, some old pipelines are due to close to reasons such as design period, geology sedimentation, surface structures, ground floras, aging and seepage are occurred in that, if excavating Replacement and Repair using overall, many unpredictable difficulties will be run into, surface structures on such as pipeline, blocked road influence traffic, the conflicting of other cross over line, cost height long in time limit, method now leading in the world is exactly various non-excavation repairing techniques.
The content of the invention
The present invention mainly solves the technical problem present in prior art, so as to provide a kind of seamless double-layer enhancing cured in place liner pipe.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of seamless double-layer strengthens cured in place liner pipe, it is characterized in that, described seamless double-layer enhancing cured in place liner pipe includes a macromolecule layer, one first reinforcement fibrous layers, one first adhesive layer, one second reinforcement fibrous layers and one second adhesive layer successively from the inside to the outside, and the second described adhesive layer is mutually be bonded with a pipeline.
As preferred embodiments of the present invention, described macromolecule layer is made up of polyurethane or flexible polyethylene, and the first described reinforcement fibrous layers and the second reinforcement fibrous layers are that terylene or aramid fiber braiding are formed.
The seamless double-layer enhancing cured in place liner pipe of the present invention has the advantage that：In pipeline non-excavation rehabilitation, only two construction holes need to be excavated during construction being repaired pipe ends, the internal lining pipe is converted into U-shaped and is drawn in pipeline, the internal lining pipe is extended using external Thermocuring equipment, so that the first adhesive layer and the second adhesive layer are simultaneously to exosmosis, so that internal lining pipe is securely fixed in the pipeline of breakage, realize that pipeline is repaired.Seamless double-layer enhancing cured in place liner tubular construction is compact, and easy construction, effect is substantially, practical.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, the required accompanying drawing used in embodiment or description of the prior art will be briefly described below, apparently, drawings in the following description are only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 strengthens the structural representation of cured in place liner pipe for the seamless double-layer of the present invention；
Wherein,
1st, seamless double-layer enhancing cured in place liner pipe；2nd, macromolecule layer；3rd, the first reinforcement fibrous layers；4th, the first adhesive layer；5th, the second reinforcement fibrous layers；6th, the second adhesive layer；7th, pipeline.
Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, apparent clearly defined so as to be made to protection scope of the present invention.
As shown in Figure 1, seamless double-layer enhancing cured in place liner pipe 1 includes a macromolecule layer 2, one first reinforcement fibrous layers 3, one first adhesive layer 4, one second reinforcement fibrous layers 5 and one second adhesive layer 6 successively from the inside to the outside, and second adhesive layer 6 is mutually be bonded with a pipeline 7.
The macromolecule layer 2 is made up of polyurethane or flexible polyethylene, and the reinforcement fibrous layers 5 of the first reinforcement fibrous layers 3 and second are that terylene or aramid fiber braiding are formed.Certainly, it is also possible using other kinds of chemical industry fiber, glass fibre can also, or woven using the composite fibre of multiple fiber.
In pipeline non-excavation rehabilitation, only two construction holes need to be excavated during construction being repaired pipe ends, the internal lining pipe is converted into U-shaped and is drawn in pipeline, the internal lining pipe is extended using external Thermocuring equipment, so that the first adhesive layer 4 and the second adhesive layer 6 are simultaneously to exosmosis, so that internal lining pipe is securely fixed in the pipeline 7 of breakage, realize that pipeline 7 is repaired.
Seamless double-layer enhancing cured in place liner tubular construction is compact, and easy construction, effect is substantially, practical.
This is not limited to, any change or replacement expected without creative work should be all included within the scope of the present invention.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
