Description
Technical field
The invention belongs to pipeline and update restorative procedure, curved pipe molding special-purpose section can be crossed particularly to a kind of no-dig technique.
Background technology
Urban discharging pipeline is referred to as " the underground life line " in city, bears the vital task of urban sewage, water drainage.I
State's urban construction scale constantly expands, and maintenance and the recovery project of drainage pipeline come into one's own all the more.Traditional pipeline rehabilitation side
Method is to use digging mode more to renew pipeline, and this causes quantities huge, expends the biggest, and cannot complete engineering in short-term,
More can cause traffic jam, environmental pollution etc., these are all that modern urban construction is difficult to bear.
Non-excavation repairing technique is that one utilizes no-dig technique or micro-excavation technology, and the underground piping damaged is carried out local
Or the engineering that entirety is repaired.It renews the technology of pipe relative to traditional excavation, has and does not affects traffic, reduces environment dirty
Dye, the engineering time is short, and workmen is few, and safety is high, the huge advantage such as integrated cost is low.Quoting of non-excavation repairing technique,
Substantially increase the probability that City Buried Pipeline updates.
The most ripe domestic trenchless repairing method mainly has soft lining method, Insertion method, broken tube method, undergauge liner
Method, spiral winding method, pipe sheet assembling method and some local route repair methods.For spiral winding method, at present, China is at circular pipe
On have wind and the grouting device of independent research.
Pipeline, culvert are after running for many years, owing to the reasons such as differential settlement or external force destruction cause interface tube to come off, from
And form certain camber.Existing pipeline trenchless repairing method, can only be wound straight tube in original pipeline, it is impossible to real
Now curved with bending through, therefore can only sacrifice internal diameter as cost, after causing reparation, pipeline is unsatisfactory for original design and operational requirement.
Existing Wrapping formed pipe is by banding section bar from coil to coil spiral winding and to be engaged molding, due to the width of banding section bar
Narrower, and hardness is relatively strong, what it was helically-wound shaped must be straight tube, and deformable amount is the least.It is thus impossible to realize with bending through
Curved.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of one realizing curved pipe molding is non-
Excavation can cross curved pipe molding special-purpose section.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of no-dig technique can cross curved pipe molding special-purpose section, it is characterised in that: by section bar body, snap close draw-in groove, snap close
Dop, reinforcement rib and upward bending portion are constituted, and are shaped with snap close draw-in groove in the one end in section bar body width direction, at section bar body
The other end of width is shaped with snap close dop, is shaped with reinforcement rib at the middle part of section bar body, is shaped with in the middle part of section bar body
Upward bending portion, provided the deflection of section bar when supplying curved, form pinch roller and guide between this both sides, upward bending portion and reinforcement
Groove.
And, described snap close draw-in groove is twice snap close draw-in grooves side by side, and described snap close dop is also corresponding twice
Snap close dop.
And, described snap close draw-in groove is herringbone snap close draw-in groove, and is shaped with water in the top ends of herringbone snap close draw-in groove
Flat connecting portion, provided the deflection of section bar when supplying curved.
And, described rib of strengthening is interval and the reinforcement of 2-4 road side by side rib.
Advantages of the present invention and having the beneficial effect that
1, this no-dig technique can cross curved pipe molding special-purpose section, by section bar body, snap close draw-in groove, snap close dop, ribs
Muscle and upward bending portion are constituted, and snap close draw-in groove can be mutually twisted with snap close dop, in winding process in winding process not
Disconnected advance, final Wrapping formed plastic conduit, in the middle part of section bar body, it is shaped with epirelief ten thousand pars convoluta, the spiral new pipeline tool after winding
Have certain dilatation amount, thus meet Wrapping formed during the curved requirement of mistake.
2, this no-dig technique can cross curved pipe molding special-purpose section, uses twice snap close draw-in groove side by side and snap close dop mutual
Occlusion closely, it is ensured that be wound around the pipeline produced non-leakage.
3, this no-dig technique can cross curved pipe molding special-purpose section, and snap close draw-in groove is herringbone snap close draw-in groove, and in herringbone
The tip exterior of snap close draw-in groove is shaped with level connection joint portion, during being wound around tubulation, provides the deflection of section bar, simultaneously when crossing curved
Stress is avoided to concentrate.
4, this no-dig technique can cross curved pipe molding special-purpose section, and strengthening rib is interval and the reinforcement of 2-4 road side by side rib,
The upper end strengthening rib is all shaped with support end face, can not only effectively play and prevent pipeline self expanded by heating problem on deformation,
And, after Wrapping formed pipeline external grouting, additionally it is possible to realize combination with pulp layer and play support and styling.
5, present configuration design science is reasonable, can be wound around the pipeline that makes new advances in culvert, pipeline, and new pipeline not only has good
Good pressure-bearing property and sealing, it is possible to reach the acceptance criteria of country's drainage pipeline, have simultaneously and can have with bending through curved feature
Not excavated pavement, can be the most curved advantage.
