Abstract
Enhanced internal lining pipe can be flattened the invention discloses a kind of no-dig technique pipeline rehabilitation use, it is characterized in that, described no-dig technique pipeline rehabilitation use can flatten enhanced internal lining pipe and include an internal layer, a reinforcement fibrous layers and an outer layer successively from the inside to the outside, described internal layer is made up of polyurethane or flexibility PE, and described outer layer is made up of super abrasive PE.In pipeline non-excavation rehabilitation, only two construction holes need to be excavated being repaired pipe ends during construction, the internal lining pipe is converted into U-shaped and is drawn in pipeline, two installs the original pipeline of special joint connection and accuses completion, engineering time is short, and the service life after reparation is long.The no-dig technique pipeline rehabilitation use can flatten enhanced internal lining pipe compact conformation, and easy construction, effect is substantially, practical.
Description
Technical field
The present invention relates to a kind of pipeline, more precisely, being that a kind of no-dig technique pipeline rehabilitation use can flatten enhanced internal lining 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 that enhanced internal lining pipe can be flattened by providing a kind of no-dig technique pipeline rehabilitation use.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of no-dig technique pipeline rehabilitation use can flatten enhanced internal lining pipe, it is characterized in that, described no-dig technique pipeline rehabilitation use can flatten enhanced internal lining pipe and include an internal layer, a reinforcement fibrous layers and an outer layer successively from the inside to the outside, described internal layer is made up of polyurethane or flexibility PE, and described outer layer is made up of super abrasive PE.
As preferred embodiments of the present invention, described reinforcement fibrous layers are that terylene or aramid fiber braiding are formed.
The no-dig technique pipeline rehabilitation use of the present invention, which can flatten enhanced internal lining pipe, has advantages below：In pipeline non-excavation rehabilitation, only two construction holes need to be excavated being repaired pipe ends during construction, the internal lining pipe is converted into U-shaped and is drawn in pipeline, two installs the original pipeline of special joint connection and accuses completion, engineering time is short, and the service life after reparation is long.The no-dig technique pipeline rehabilitation use can flatten enhanced internal lining pipe compact conformation, 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 can flatten the structural representation of enhanced internal lining pipe for the no-dig technique pipeline rehabilitation use of the present invention；
Wherein,
1st, no-dig technique pipeline rehabilitation use can flatten enhanced internal lining pipe；2nd, internal layer；3rd, reinforcement fibrous layers；4th, outer layer.
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, the no-dig technique pipeline rehabilitation use can flatten enhanced internal lining pipe 1 includes an internal layer 2, a reinforcement fibrous layers 3 and an outer layer 4 successively from the inside to the outside, the internal layer 2 is made up of polyurethane or flexibility PE, and the outer layer 4 is made up of super abrasive PE.
The reinforcement fibrous layers 3 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 being repaired pipe ends during construction, the internal lining pipe is converted into U-shaped and is drawn in pipeline, two, which installs special joint and connects original pipeline, accuses completion, engineering time is short, and the service life after reparation is long.
The no-dig technique pipeline rehabilitation use can flatten enhanced internal lining pipe compact conformation, 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.
