Technical field
The utility model relates to employed rubber plug in the municipal drainage pipeline closed-water test.
Background technique
The drainage pipe closed-water test is the important link of newly-built function pipeline test, it not only can verify the leakproofness that whether satisfies design and code requirement after pipeline is completed, simultaneously it can prevent can also prevent that effluent seepage is to the pollution of underground water resource environment in the pipeline because pipe leakage causes adverse effects such as depression that road and other structure are brought, destruction.
The drainage pipe closed-water test is to be undertaken by the well section, adopts the plug shutoff need do the upstream and downstream tube opening of experiment well section earlier, is filled to 2 meters high heads of the upstream mouth of pipe by inspection shaft in pipeline again, observes the pipeline water percolating capacity after 24 hours, the leakproofness of checking pipeline.
There is following shortcoming in the brick plug closed-water test of tradition:
(1) the brick plug activity duration long, have hidden danger of quality
The brick plug of drainage pipe closed-water test is arranged on required test pipe upstream and downstream inspection shaft inner spout position usually, small-caliber pipeline adopts two or four cement brick walls to carry out shutoff, big-diameter pipeline adopts the pseudo-ginseng cement brick wall to carry out shutoff, and body of wall is carried out at least twice whitewash, to guarantee that body of wall and body of wall periphery does not seep water with the inner-walls of duct contact position, treat that body of wall and powder face intensity reach the requirement rear and can water filling carry out closed-water test in pipeline, these early-stage preparations need two days time (winter time can be longer) at least.
In actual building process, brick wall and arc pipe inwall surface of contact may be clogged unreal by mortar, stay hidden danger, be easy to after the pipeline water filling, seepage appears in body of wall and arc pipe internal face contact position, influence the accuracy of pipeline closed-water test data, seeping water, all that has been achieved is spoiled for serious this segment pipe closed-water test that will cause, and the water in the pipeline is drained, and handles plug, again water filling is tested, and causes water resource waste.
(2) brick plug is removed inconvenience, has potential safety hazard, does not meet environmental requirement
After brick plug drainage pipe closed-water test is finished, must in time plug be cut, clear up, because when building plug by laying bricks or stones, for guaranteeing strength of wall body and water-proof performance, the proportioning of mortar is bigger, causes strength of wall body higher.Remove, need at least when clearing up two personnel coordinating operation in checking also, working space is little, and extremely inconvenient, underground work exists serious potential safety hazard; Sometimes because negligent supervision, brick plug is pounded except that not thorough, the discharge area of pipeline reduces, between the rainy season storm period, the upstream line discharge pressure is bigger, and pipeline is not smooth again, tends to occur the upstream inspection shaft and seriously emits water, set about nowhere during maintenance, bring very big inconvenience for urban traffic environment and resident living.
The brick slag waste material that brick plug is removed needs to be wasted time and energy by manually handling on the road surface at the bottom of the inspection shaft, also need clear for constructional rubbish simultaneously, does not meet environmental requirement.
Summary of the invention
The purpose of this utility model provides a kind of novel drainage pipe closed-water test rubber plug, this rubber plug has good physical and mechanical properties index, after guaranteeing that the utricule inflation adds compression swelling, rubber bag tank closely contacts with inner-walls of duct, guarantee the not outside seepage of the water of being annotated in the pipeline, the frictional resistance that produces with utricule that adds compression swelling and pipeline is enough to keep out the water pressure after the water filling in the pipeline.This rubber plug possesses high strength, advantage cheaply.
The technological scheme that realizes the utility model purpose is: a kind of novel drainage pipe closes the water rubber plug, plug is a rubber tyre, and be fixed on the support, gas-filled switching tube valve, pressure gauge are connected with rubber tyre, safe voussoir is connected with support, drain valve is set on the support, and described rubber tyre is formed by outermost gum capsule, middle canvas and the compacting of internal layer rubber.
The support of rubber plug can being made of one or made up.
The advantage that the utlity model has
(1) simple to operate, activity duration weak point
After rubber plug was placed in mouth of pipe relevant position, water filling in utricule (gas) pressurization made its expansion, kept utricule closely to contact with inner-walls of duct, and produced enough frictional force and get final product, and general need 2～3 hours.
(2) remove conveniently, job safety, reusable, compliance with environmental protection requirements
After the drainage pipe closed-water test is finished, after the test water of being annotated in the pipeline need only being discharged by the drain valve that is provided with in the middle of the support is loosening when removing this rubber bag tank plug that the utricule outlet valve is loosening, the gas in the utricule is discharged, take out water pocket.This rubber pneumatic bag plug can be repeatedly used, and meets safe ready, the economical environment-protective requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of novel drainage pipe closes the water rubber plug, it consists of " Steel Bracket+high-strength inflating rubber tire " form, and this plug outside is the high-strength rubber tyre 3 of a circle reinforcement, and a gas-filled switching tube valve 7, band pressure gauge 8 inflated hoses are set on rubber tyre.Rubber tyre 3 is fixed on the special support 5, drain valve 9 is set on support 5, it is after water discharged in the pipeline 1 after closed-water test was finished that this valve mainly acts on, remove rubber plug again, forbid that the mode of earlier inflation in the rubber tyre being discharged takes down rubber plug, hurt the operating personnel otherwise can the rubber utricule be gone out because of the pressure of water in the pipeline.Be connected with three voussoirs 2 on the Steel Bracket 5, after rubber plug is put into pipeline 1, under the pressure of water, produce displacement, place these wedge-shaped blockss, guarantee personnel, device security in the plug using process in three points of Steel Bracket position for preventing plug.Rubber tyre 3 outermost surfaces of described rubber plug are made up of gum capsule 4, and the centre adds certain high-strength canvas, form as " muscle " of whole rubber tyre and the compacting of internal and external layer rubber.Outlet pipe 6 feeds in the outermost gum capsule 4.
Adopting the way that increases canvas in the rubber utricule, also is at twice according to the punching block size compression moulding that sets.Suppressing for the first time the gum capsule of 1cm thickness, is for the second time to suppress with the rubber bag tank of moulding for the first time shifting to an earlier date ready-made canvas " bag " and internal layer rubber.
This scheme adopts rubber to combine with canvas, and the overall flexibility of rubber utricule and intensity are significantly improved, and the distortion more than needed of utricule is also less.Simultaneously the caliber scope of its drainage pipe of being suitable for is bigger, installs, dismounting is all very convenient, and the frequency of Shi Yonging increases repeatedly.
