Description
Technical field
The present invention relates to a kind of plastic inspection well leak tightness test device and detection method, belong to properties of product and detect and test field.
Background technology
Inspection chamber, is commonly called as " Jiao Jing ", is the vertical shaft built at a certain distance on underground utilities position, is one of urban road underground foundation facility, mainly for service conduits, removing mud and the structures in order to connect different directions, differing heights pipeline.Major part is located on turning, pipeline intersection, caliber or gradient change place, drop place and straight line pipeline section.Plastic inspection well, can all-weather construction owing to having good airproof performance, does not restrict by weather, can Split assembled, energy height up and down, drainage performance is excellent, easy construction, lightweight, be easy to transport, short construction period, comprehensive cost is low, the advantages such as maintenance cost is few, and progressively instead of the inspection chamber of traditional brickwork construction or reinforced concrete structure.Shaping plastic inspection well is welded by different piece, the techniques such as socket joint connection assemble, because plastic inspection well is embedded in underground activities, infiltrate in plastic inspection well to prevent the liquid of surrounding soil, or cause leakage pollution to prevent the corrosive liquids in pipeline from infiltrating surrounding soil, so must detect the sealing of plastic inspection well, and the pick-up unit of existing plastic inspection well adopts traditional Material Testing Machine test platform to reach mostly, mostly can only detect the mechanical property of plastic inspection well, and can not its sealing be detected, and there is no special plastic inspection well experiments of sealing performance testing equipment.For addressing this problem a kind of plastic inspection well impermeability test pick-up unit that must design.
Summary of the invention
The object of this invention is to provide a kind of plastic inspection well leak tightness test device and detection method, in order to detect the sealing property of plastic inspection well, solve the problem of plastic inspection well sealing property without special detection device.
The present invention realizes by following technical scheme: a kind of plastic inspection well leak tightness test device, comprises support 1, worktable 2, O-ring seal 3, water injection hole 4, plastic inspection well 5, locking anchor ear 7; Support 1 is fixed on ground by foot bolt, worktable 2 is arranged on support 1 by bolt, and O-ring seal 3 is arranged on worktable 2, worktable 2 offers water injection hole 4, plastic inspection well 5 is arranged on worktable 2 top by locking anchor ear 7, is provided with weld seam 6 in the middle part of plastic inspection well 5.
Described plastic inspection well leak tightness test device detection method, first plastic inspection well 5 well head made is placed on worktable 2 down, with locking anchor ear 7, plastic inspection well 5 is locked on worktable 2, do not come off during to ensure well head positiver sealing and to pressurize, water injection hole 4 again by worktable 2 is offered fills press water to given pressure in plastic inspection well 5, pressurize, to preset time, observes the leakage flow size of press water and the pressure release speed of pressurize.
In plastic inspection well 5, note press water by water injection hole 4, hydraulic pressure is by force 0.1 ~ 2MPa.
In plastic inspection well 5, press water is noted, 0.5 ~ 30 minute dwell time by water injection hole 4.
The principle of work of a kind of plastic inspection well leak tightness test device and detection method is: in plastic inspection well 5, note press water by water injection hole 4, when 3DT energising makes three-position four-way electromagnetic directional valve 10 switch to right position, hydraulic pump 9 continues to supply water to plastic inspection well 5 by hydraulic control one-way valve 11 and water injection hole 4, when reaching electro connecting pressure gauge 12 predetermined pressure higher limit, electro connecting pressure gauge 12 sends signal, it is electromagnet 3DT power-off, three-position four-way electromagnetic directional valve 10 is switched to meta, hydraulic pump 9 is unloaded by electricity liquid ratio relief valve 8, plastic inspection well 5 is by hydraulic control one-way valve 11 pressurize, if make the pressure in plastic inspection well 5 lower than the pressure upper limit value of electro connecting pressure gauge 12 owing to leaking, then electro connecting pressure gauge 12 sends signal again, electromagnet 3DT is energized, three-position four-way electromagnetic directional valve 10 is switched to right position, hydraulic pump 9 supplies water to plastic inspection well again, after reaching the dwell time, electromagnet 2DT is energized, three-position four-way electromagnetic directional valve 10 is switched to left position, plastic inspection well 5 pressure release.By setting up the pressure upper limit value of electro connecting pressure gauge 12, pressurize can be carried out to plastic inspection well 5 according to different pressure.
After filling water under high pressure in plastic inspection well 5, water under high pressure acts on plastic inspection well 5 barrel surrounding, acts on the mutual counteract of hydraulic pressure acting force of well bore wall radial direction, but can make a tympanites.Act on the hydraulic pressure acting force at well bore wall top, direction vertically upward, pit shaft is made to have the trend axially upwards stretched, and pit shaft body bottom is by locking anchor ear 7 and worktable 2 consolidation, act on the hydraulic pressure acting force on well bore wall bottom worktable 2, direction vertically downward, pit shaft is made to have the trend axially stretched downwards, thus make plastic inspection well 5 cylindrical shell receive axial acting force up and down, this makes plastic inspection well 5 produce axial tension to power, weld seam 6 place is the weakness of axial tension power, and what be first damaged should be weld seam 6 place of plastic inspection well 5.Therefore, high pressure water injection pressurization reaches the object that weld seam 6 place impermeability test detects.
The present invention has following beneficial effect:
1, experimental provision sealing joint place adopts two-stage sealing to add anchor ear lock sealing, can better ensure the security of reliability and the test sealed;
2, test unit can according to working-yard, and by worktable to being buckled in plastic inspection well well head, carry out impermeability test detection to the inspection chamber of having constructed and pipeline, test unit function is many;
3, test unit pressure testing water also can adopt pressurized air, observes the pressure release speed of compressed-air actuated leakage gas flow and pressurize to judge sealing;
4, equipment is simple and reliable, floor area is little, not by inspection chamber height limitation;
5, easy to operate simple, cost is low.
