Abstract
The utility model discloses a repairing device of a local water leakage mouth of a large-diameter pipe. The repairing device comprises rubber sealing strips and a plug sheet. The plug sheet is tightly connected with the periphery of the water leakage mouth through the rubber sealing strips, the water leakage mouth is sealed through the rubber sealing strips and the plug sheet, and a first stainless steel strip and a second stainless steel strip used for expanding the water leakage mouth are arranged on the inner wall of a drain pipe on two sides of the water leakage mouth. The water leakage mouth is sealed through the rubber sealing strips, so that quite good leakproofness can be achieved, and an original connector is allowed for a certain degree of dislocation; the stainless steel strips are utilized to press on two sides of the water leakage mouth, so that the water leakage mouth can be expanded better, and the plug sheet can be better fitted to the periphery of the water leakage mouth.
Description
Technical field
The utility model designing and arranging water pipe field, relates in particular to the prosthetic device of the local scupper of a kind of heavy caliber drain pipe.
Background technology
At present, large diameter pipeline adopts trenchless rehabilitation mode conventionally, and because caliber is excessive, excavation soil layer is too much, puts slope excessive etc. former
Because causing road excavation huge, in work progress, the floor space such as equipment, tubing is excessive, thereby cause the stagnation of periphery traffic paralysis and periphery communal facility, mainly adopt non-excavation pipe rehabilitation technology so solve at present the problem of large diameter pipeline reparation.
The local recovery technique of conventional non-excavation pipeline, as around-France in steel bushing, embedding reinforcing method, resin solidification method etc. respectively have pluses and minuses, and recoverable defect type also has difference: the around-France meeting of steel bushing causes pipeline effective cross sectional area to reduce; After the reparation of embedding reinforcing method, there is no ring-type overall structure, easily come off; Though resin solidification has structural and advantage that be close to concurrently, it can only adopt air bag to install, and is not suitable for heavy caliber (more than DN1000) pipeline.And existing gutter maintenance major technique, material are all from abroad, introduce cost higher; Every kind of construction technology has limitation.
Summary of the invention
In order to solve the problems of the prior art, the purpose of this utility model is to provide the prosthetic device of the local scupper of a kind of heavy caliber drain pipe.Its good airproof performance, simple in structure, easy for installation.
For achieving the above object, the utility model adopts following design scheme, the prosthetic device of the local scupper of a kind of heavy caliber drain pipe, it comprises rubber weather strip, patch, described patch is closely connected with the surrounding of scupper by rubber weather strip, rubber weather strip and patch seal up scupper, on the gutter inwall of rubber weather strip both sides, be provided with the first stainless steel strip and the second stainless steel strip for expanding scupper, on the gutter inwall of scupper both sides, be provided with the first baffle plate and the second baffle of location patch.
Preferably, described the first stainless steel strip and the second stainless steel strip are fixed by welding on gutter inwall.
Preferably, described the first baffle plate and second baffle are fixed by welding on gutter inwall.
Preferably, described the first baffle plate is screwed on the inwall of gutter, and second baffle is fixed by welding on gutter inwall.
Preferably, on gutter outer wall corresponding to patch, be provided with the pad matching with gutter amplitude.
Preferably, the thickness of described pad is 3mm ~ 5mm.
Preferably, the width of described the first stainless steel strip and the second stainless steel strip is 50mm, and thickness is 3mm.
The beneficial effects of the utility model are: adopt above design scheme: pipe leakage mouth adopts rubber weather strip sealing, therefore makes it have extraordinary sealing, can allow the dislocation to a certain degree of former interface simultaneously; Adopt stainless steel strip to be pressed on scupper both sides, can better strut scupper, make patch better be close to scupper surrounding; Meanwhile, at the baffle plate that location patch is installed, better prevent that patch from coming off, being shifted.Its cost of the utility model is low, consumes resources is few, and technical requirements is low, easy for installation, has very strong practicality.
brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the partial schematic sectional view of the utility model embodiment mono-;
Fig. 2 is the partial schematic sectional view of the utility model embodiment bis-.
detailed description of the invention
embodiment mono-:
As shown in Figure 1, the utility model discloses the prosthetic device of the local scupper of a kind of heavy caliber drain pipe, it comprises rubber weather strip 1, patch 2, described patch 2 is the position with patch 2 in scupper 3(figure by rubber weather strip 1) surrounding be closely connected, rubber weather strip 1 and patch 2 seal up scupper 3, on gutter 4 inwalls of rubber weather strip 1 both sides, be provided with the first stainless steel strip 5 and the second stainless steel strip 6 for expanding scupper 3, on gutter 4 inwalls of scupper 3 both sides, be provided with the first baffle plate 7 and the second baffle 8 of location patch 2.
Wherein, described the first stainless steel strip 5 and the second stainless steel strip 6 are fixed by welding on gutter 4 inwalls (in figure, black part is divided into tin cream), and described the first baffle plate 7 and second baffle 8 are fixed by welding on gutter inwall.On gutter 4 outer walls of patch 2 correspondences, be provided with the pad 9 matching with gutter 4 amplitudes.The thickness of described pad 9 is 3mm.Pad 9 is further better fixed patch 2 and is prevented pipe leakage.6 width of described the first stainless steel strip 5 and the second stainless steel strip are 50mm, and thickness is 3mm.
Embodiment bis-:
As shown in Figure 2, different from embodiment mono-, in the present embodiment
The first baffle plate 7 is fixed on by screw 11 on the inwall of gutter 4, and second baffle 8 is fixed by welding on gutter 4 inwalls, on gutter 4 outer walls of patch 2 correspondences, can not be provided with pad 9.
Concrete maintenance process of the present utility model is:
First according to the data information that early stage, pipeline CCTV detected, determine the pipe diameter that will repair; Carry out again the material making of factory according to size; Meet at the construction field (site) after mounting condition and (complete after shutoff precipitation), manually entering pipeline installs, first carry out pre-slip casting and patching at pipe joint place, again by manually rubber weather strip being fixed on to gutter scupper place, then the first stainless steel strip and the second stainless steel strip are installed on respectively to the both sides of rubber weather strip, withstand the first stainless steel strip and the second stainless steel strip by jack, expansion scupper is to correct position, fill in again patch, and then locating patch with the first baffle plate and second baffle.
