Description
Technical field:
The utility model relates to a kind of pipeline sealing device, is particularly applicable to the sealing device between the service sleeve of enterprise or municipal wastewater pipe network inner concrete manhole and gutter.
Background technology:
Current enterprise and municipal wastewater pipe network, drainage pipe and concrete inspection well junction, generally to take in concrete inspection well construction pre-buried diameter slightly larger than the sleeve pipe of flowing line, facilitate the integral construction of flowing line, gap encapsulant shutoff between two pipes, if can not this gap of effective sealing, large amount of sewage will be had to permeate the ground at this gap place contaminated soil and underground water source, for preventing pollution thing leaks into the outer contaminated soil of manhole and groundwater resources, current sewage inspection well turnover flowing line construct with borehole wall shell clearance in seal approach mainly at service sleeve and pass in and out gutter two ligament and fill lead, asbestos cord, packing, sealing cement or welding, but change owing to managing interior medium temperature, manhole differential settlement, the uneven reason such as stressed of pipeline, can cause between sleeve pipe and supervisor and produce gap, the various places enterprise of current this seepage in the whole nation and city planting ductwork have existence, it is one of key factor causing China's underground water source to pollute.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of good seal performance and not easily affects manhole service sleeve and the gutter gap rubber sealing device of sealing performance because of external environment change.
For solving the problem, the utility model is achieved through the following technical solutions:
A kind of manhole rubber pipeline sealing device, the borehole wall of manhole is provided with a service sleeve leant out, a gutter is socketed with in described service sleeve, described sealing device comprises sealed tube body, sealed tube body is that the gutter seal section of the larger-diameter service sleeve seal section of profile all in cylinder type and small diameter and flexible strengthening segment form by two ends, described service sleeve seal section and the service sleeve be placed on the borehole wall are closely socketed, described gutter seal section and gutter can closely be socketed, described service sleeve seal section and gutter seal section are connected as one by flexible strengthening segment, this structure can better ensure service sleeve and pipeline clearance seal, and when causing piping displacement because of outside cause, due to the effect of elastic telescopic, also the sealing in gap can effectively be ensured.
As preferably, be convenient to for making described manhole rubber pipeline sealing device install, and in order to allow described service sleeve and gutter junction can have enough telescopic resiliences under extraneous stressing conditions, described flexible strengthening segment is the bellows that dilatability is greater than 350%.
As preferably, for making the better tightness of manhole rubber pipeline sealing device, described sealed tube body two ends are clamped by special mould clamp seal with corresponding interior service sleeve and the gutters of being socketed in.
As preferably, described sealed tube body pipe thickness is 3mm-5mm.
Compared with prior art, usefulness of the present utility model is: described manhole rubber pipeline sealing device is adopted two sections of concentric reducer cylindrical rubber structures and is connected by a flexible pipeline section, mutually be socketed with manhole service sleeve and flowing line and seal and clamped by special mould clamp fixing, therefore, not only ensure that the sealing in service sleeve and gutter gap, and when extraneous environmental change, also can there is good compliance, thus ensure that pipeline junction gap has stable lasting sealing performance.

Detailed description of the invention:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of manhole rubber pipeline of the utility model sealing device, as Figure 1-3, the borehole wall 8 of manhole is provided with a service sleeve leant out 4, a gutter 5 is socketed with in described service sleeve 4, described sealing device comprises sealed tube body 1, sealed tube body 1 is that the larger diameter service sleeve seal section 2 of profile all in cylinder type and small diameter gutter seal section 3 and flexible strengthening segment 6 form by two ends, described service sleeve seal section 2 is closely socketed with the service sleeve 4 be placed on the borehole wall 8, described gutter seal section 3 can closely be socketed with gutter 5, described service sleeve seal section 2 and gutter seal section 3 are connected as one by flexible strengthening segment 6, the concrete length of described sealed tube body 1 is depending on the situation of flowing line, when actual installation, one end service sleeve seal section 2 of described sealed tube body 1 is socketed on the manhole borehole wall 8 service sleeve 4, other end gutter seal section 3 is socketed on gutter 5, middle connected by flexible strengthening segment 6, therefore, effectively can not only ensure sealing performance, and when being caused piping displacement by outside cause, due to the effect of elastic telescopic, also the sealing that maintenance that can be stable is good, in addition, durability degree is had more for making described manhole rubber pipeline sealing device, described sealed tube body 1 selects acid and alkali-resistance, corrosion-resistant, the flexible rubber of oil resistant.
Preferably, as shown in Figures 1 to 4, be convenient in Specific construction process for making described manhole rubber pipeline sealing device install, described flexible strengthening segment 4 is set to the good bellows of retractility, dilatability requires to be greater than 350%, therefore, under manhole differential settlement or the uneven situation impact such as stressed of pipeline, also can there be enough telescopic resiliences described service sleeve 4 and gutter 5 junction to adapt to outer change of answering environment, still can keep good sealing performance.
Preferably, as shown in Figure 1, described sealed tube body 1 two ends are all clamped by special mould clamp 7 seal with corresponding interior service sleeve 4 and the gutters 5 of being socketed in, make the sealing meeting in gap, junction between the service sleeve 4 on the manhole borehole wall 8 and gutter 5 better like this, in addition for keeping the durability of special mould clamp 7, corrosion resistant coating can be coated in jig 7 surface, described left and right.
Preferably, described sealed tube body 1 pipe thickness is 3mm-5mm, so not only saves material, and effectively ensures the durability of sealed tube body 1.
Preferably, described service sleeve 4 leans out more than 5MM at the borehole wall 8 place, specifically determines by practice of construction installation situation, be conducive to like this in order to special mould clamp 7 seal construction.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
