Description
Technical field
The utility model belongs to the water supply and sewage work technical field, relates to a kind of non-trenchless rehabilitation partial collapse plumbing installation.
Background technology
In recent years,, had a strong impact on people's normal life order, and therefore, in time repaired broken pipe and seem particularly important because the news of the surface collapse that the sewer breakage causes is of common occurrence.
Common pipeline rehabilitation device is through the excavation road pipeline to be carried out replace tubes to handle, the method not only the duration longer, and cost is higher.But not the method for trenchless rehabilitation sewer can repair the piping failure point when not influencing road traffic fast and accurately, thereby recovers people's life order as early as possible.But the method and apparatus of existing non-trenchless rehabilitation sewer mainly is to lean against former inner-walls of duct to do liner, or when former pipeline abolished, newly pulls the method for one section new pipe into and repair.The former major defect be can not to pipeline as a result the part of well damage repair, the latter's main limitation is that workload is bigger, relates to the repairing of whole segment pipe, can not repair the part.And existing pipeline rehabilitation device all needs the constructor to get into pipeline reparation, has certain danger.
Summary of the invention
To the problems referred to above; The utility model provides a kind of non-trenchless rehabilitation partial collapse plumbing installation, and this device can not get into pipeline the constructor, guarantees under its safe situation; Pipeline configuration is destroyed serious place to be recovered and reinforces; Repair the sewer local damage or break and cave in, make the sewer operation normal, guarantee the normal operation of productive life thereby reach.
For realizing above-mentioned purpose, the utility model provides following technical scheme:
A kind of non-trenchless rehabilitation partial collapse plumbing installation, it is characterized in that: this device comprises surveillance 3;
Stainless steel inner sleeve 1, it is formed by the corrosion resistant plate coiling, and caliber is less than the caliber of the pipeline that caves in, and the interface behind the coiling is furnished with unidirectional sawtooth 11, and the outer most surrounding of stainless steel inner sleeve 1 is furnished with hydro-expansive rubber circle 10;
Said hydraulic dilatation device 2 is fixed on its outside stainless steel inner sleeve 1 through arranging inner sleeve fixed head 8 above that.
Radial distribution is fluted on the said stainless steel inner sleeve 1, and hydro-expansive rubber circle 10 is arranged in the said groove.
The degree of depth of said groove is smaller or equal to the thickness of said hydro-expansive rubber circle 10.
Said surveillance is a closed-circuit television.
Compared with prior art, the beneficial effect of the utility model is:
(1) adopt jack in the utility model, its effective travel can be guaranteed the pipeline of different damaged situation is repaired;
(2) the utility model adopts the stainless steel inner sleeve that stainless plate is processed, and through the design and the selection of steel plate thickness, the rigidity requirement that the inner sleeve after the repairing is reached can be guaranteed to repair back pipeline input and normally use;
(3) the stainless steel inner sleeve outside of the utility model guarantees not exist between the new and old pipe leakage situation to take place after coming into operation in the later stage according to the hydro-expansive rubber circle of caliber customization.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, further explain the utility model.
As shown in Figure 1, a kind of non-trenchless rehabilitation partial collapse plumbing installation of the utility model comprises stainless steel inner sleeve 1, hydraulic dilatation device 2 and surveillance 3.
Wherein, as shown in Figure 6, stainless steel inner sleeve 1 is formed by the corrosion resistant plate coiling, and its caliber carries out customized in advance less than the caliber of the pipeline that caves in according to the caliber of being repaired in the practical operation.And to the selection of corrosion resistant plate, the rigidity that also requires its stainless steel inner sleeve 1 of processing to be reached can be guaranteed to repair back pipeline input and normally used.The interface of the stainless steel inner sleeve 1 that is wound into is furnished with unidirectional sawtooth 11; Unidirectional sawtooth 11 can guarantee to be in the external force effect of the hydraulic dilatation device of portion within it of ducted stainless steel inner sleeve 1 and descend by after the expansion; Even after cancelling the external force effect; Still keep expansion state, do not restore to the original state, see also Fig. 4.
And the outer most surrounding of stainless steel inner sleeve 1 is furnished with hydro-expansive rubber circle 10, can fill the pipeline repaired and the slit between the stainless steel inner sleeve 1, prevents to reveal.For better fixedly hydro-expansive rubber circle 10, radial distribution is fluted on the stainless steel inner sleeve 1, and hydro-expansive rubber circle 10 is arranged in the groove.Wherein, the degree of depth of groove is smaller or equal to the thickness of said hydro-expansive rubber circle 10.
Shown in Fig. 2-5; Hydraulic dilatation device 2, the inside that it is positioned at stainless steel inner sleeve 1 comprises patcher car body 9; The hydraulic jack 5 that one end is fixedly connected on the patcher car body 9, the other end is fixedly connected with expansion steel plate 4, and the control system that rest on the ground.
The course of work:
At first, before pipeline is caved in entering, stainless steel inner sleeve 1 is fixed on the outside of hydraulic dilatation device 2 through inner sleeve fixed head 8.Through observing surveillance 3; The wheel 7 that utilizes patcher car body 9 is transported to the B of piping failure place with the device of the utility model, starts hydraulic dilatation device 2 through the control system, and sets the expansionary force that is fit to; Hydraulic jack 5 is expanded outwardly; Be positioned at hydraulic dilatation device 2 outside stainless steel inner sleeves 1 simultaneously and under the effect of expansionary force, expand, when touching the piping failure position, the power of hydraulic jack 5 is pushed up back original position with the piping failure place.After the completion to be repaired, cancel the power of hydraulic jack 5, and pass through patcher car body 9 hydraulic dilatation device 2 is regained through the control system.And simultaneously because stainless steel inner sleeve 1 is provided with unidirectional sawtooth 11, recall the expansionary force of hydraulic jack 5 after, the state after it still keeps expanding.
Detect the situation of caving in the pipeline through surveillance,, can also carry out the second time and repair if piping failure length is longer.
