Description
Technical field
The utility model relates to a kind of flood protection materials, particularly relates to a kind of leak stopping sleeve.
Background technique
In the blocking construction of subterranean pipe line, usually adopt inversion method, the material of inversion method generally is to do skeleton by porous materials such as more pliable and tougher polymer, glass fiber cloth or non-woven fibres, form through the saturated resin material soaking, outer general one deck water-separating film that covers at material, after upset was lining into pipeline, this water-separating film became the internal layer of new pipeline, mainly plays the sealing effect.Under the effect of the hydraulic pressure in the construction, air pressure or winch pulling force, inner lining material upset enters after the pipeline resin solidification under the effect of hot water water temperature or steam temperature, and inner lining material forms hard inner-walls of duct and becomes the part of pipeline skeleton.Existing product can only be repaired in the homogeneous tube road, can not carry out the part and repair.
The model utility content
The purpose of this utility model is in order to solve the existing defective of leak stoppers in the prior art, to provide a kind of leak stopping sleeve that can be used for local reparation to solve the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of leak stopping sleeve, comprise: by the cylinder that stainless steel sheets is rolled into, the two ends of described cylinder are outwards perk all, is nested with rubber sleeve on the outer wall of cylinder, the two ends of described rubber sleeve are respectively equipped with some projections, and each end of described rubber sleeve is equipped with some rubber rings;
Wherein, one end of described stainless steel sheets is provided with the some grooves that are arranged in parallel, described groove inboard is respectively equipped with a breach, the other end of stainless steel sheets is provided with the some buckle rows that are arranged in parallel, the quantity of described buckle row, groove and breach is identical, and buckle row, groove and breach are on the same straight line.
As preferred version, described stainless steel sheets is rectangular, and described groove is arranged along the broadside of stainless steel sheets, and described buckle row also arranges along the broadside of stainless steel sheets, and the straight line that groove, buckle row, breach become is parallel with the long limit of stainless steel sheets.
As preferred version, the surface of described stainless steel sheets is provided with some recessed parallel with the long limit of stainless steel sheets, and described stainless steel sheets surface forms the outer surface of cylinder after stainless steel sheets is rolled into cylinder, and described buckle row, groove, breach all are on recessed.
As preferred version, the notch length on the described stainless steel sheets is 5 ~ 15% of stainless steel sheets length.
As preferred version, described stainless steel sheets is 316 stainless steel sheets, and described rubber sleeve is made by the rubber of water-swellable.
As preferred version, the quantity of the buckle row on the described stainless steel sheets is 4 ~ 6.
As preferred version, the cross section of described rubber ring is triangular in shape.
As preferred version, the buckle quantity in the described buckle row is 4 ~ 8.
The beneficial effect that the utlity model has: repair applicable to the part of pipeline, simple to operation, be particularly useful for the leak stopping that produces in the following joining portion of caliber Φ 700mm and the crack, need not to excavate road.
Description of drawings
