Description
Technical field
The invention belongs to pipe leakage test methods, more particularly, to a kind of leak test method of drainage pipeline.
Background technique
Currently, the installation of outside line drainage pipeline is typically all that operator constructs by the experience of oneself, and arranges in outside line
It is most after waterpipe installation not do leak test, therefore the leakage scenarios of outside line drainage pipeline, than more serious, which drains
What is carried inside pipeline is all that sanitary sewage and municipal administration are lauched, if a large amount of necessarily lead to environmental pollution toward external leakage.
Summary of the invention
It is not only easy to operate, low in cost the purpose of the present invention is to propose to a kind of leak test method of drainage pipeline, and
And test effect is good, reduces pollution sources, is conducive to environmental protection.
A kind of the object of the present invention is achieved like this: leak test method (abbreviation leak test side of drainage pipeline
Method), it is to be excavated respectively at the position for corresponding to the outside line drainage pipeline left and right ends to leak test and build into left and right operation
Well, for operating personnel's operation, the left and right ends to the outside line drainage pipeline of leak test are installed plugging plate respectively and are sealed herein
It closes, left union elbow is installed in aperture on left plugging plate, left visual plastic tube is connected on left union elbow, this left visual plastics
Pipe elevates above the soil to be connected with the water tank equipped with water gage and the water outlet with valve of setting on the ground, in right plugging plate
Right union elbow is installed in top aperture, and right visual plastic tube is connected on right union elbow, and the lower section of this right visual plastic tube is in
Ground is vertically extended vertically out, and the middle section of right visual plastic tube is stretched in a horizontal left side, the upper section of right visual plastic tube is in vertical again
It is stretched on vertically and is fixed (binding) on inserting vertical posts on the ground, which can be reinforcing bar or bamboo pole, and the right side can
Vertical height depending on the upper section of plastic tube should be higher than that 0.5-1 meter of height of water tank, while use on the upper section of right visual plastic tube
The corresponding mark scale of crayon, the internal diameter convenient for the height of water level in observation tube, the left and right visual plastic tube are not less than 25mm,
In addition, open up threaded sewage draining exit and corresponding installation plug screw or blowdown valve in the lower part of right plugging plate, for discharging water, blowdown；
Then, tap water is uniformly slowly infused in water tank with external running water pipe, tap water is gone out by water tank lower bands valve
The mouth of a river and left visual plastic tube flow into the outside line drainage pipeline of leakage test for seep, this tap water note overflows to from right visual plastic tube
Until out, the valve of water tank lower part is closed, at this time the water level of left and right visual inside of plastic tubes is adjusted on plastic tube
The observation position of port 100mm, observation test water level should as long as no apparent water level decreasing in left and right visual plastic tube
Outside line drainage pipeline does not just leak greatly, and leak test is qualification, because the seal degree of each interface of outside line drainage pipeline is lower,
There is slight, slow leakage to belong to normal.
The leak test method of self-overflow type outside line drainage pipeline proposed by the invention, it is not only easy to operate, low in cost,
And test effect is good, reduces pollution sources, is conducive to environmental protection.
Specific embodiment
Below in conjunction with the embodiment of the present invention, the technical solution in the present invention is clearly and completely described, is shown
So, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
In five kilometers of long Construction of sewer of a municipal administration, since the construction period needs, engineering subcontract is given
Liang Jia unit in charge of construction, struggles hard day and night by everybody, requires the last week to complete construction in time limit for contract finally.However at this point, Party A
It is required that carrying out leak test to this five kilometers of drainage pipelines, one week time carried out leak test to five kilometers of drainage pipelines, such as
Fruit is unable to complete on the duration according to traditional test method.We just use this leak test method at this time, with each blowdown
Negative well divides ten sections to carry out leak test simultaneously, using ten discarded metal buckets, repacks water tank into respectively as operation well,
The right side of water tank installs water gage and installs the water outlet with valve in the left side of water tank, while having made 20 plugging plates, purchases
Having bought 80m internal diameter is the lucite pipe of 30mm as visual plastic tube, forms the utensils of ten sets of test leakages, arranges at each section
The left and right ends of waterpipe are installed plugging plate respectively and are closed, and left union elbow is installed in aperture on left plugging plate, left curved
Left visual plastic tube is connected on pipe fitting, the water equipped with water gage that this left visual plastic tube elevates above the soil with setting on the ground
The water outlet of case is connected, and installs right union elbow in the top aperture of right plugging plate, connects on right union elbow right visual
The lower section of plastic tube, this right visual plastic tube extends vertically out ground in vertical, and the middle section of right visual plastic tube is in a horizontal left side
Stretch, the upper section of right visual plastic tube be in again it is vertical vertically on stretch and be fixed (binding) and inserting vertical posts on the ground
On (reinforcing bar), the height that the vertical height of the upper section of right visual plastic tube is higher than water tank is 0.5 meter, while in right visual plastic tube
Upper section on the corresponding mark scale of crayon, with the height of water level in observation tube, in addition, opening up band spiral shell in the lower part of right plugging plate
The sewage draining exit of line simultaneously corresponding installation blowdown valve, for discharging water, blowdown；Then, with external running water pipe uniformly slowly toward water
Tap water is infused in case, tap water flows into the row of leakage test for seep by the water outlet and left visual plastic tube of water tank lower bands valve
In waterpipe, this tap water note closes the valve of water tank lower part until overflowing from right visual plastic tube, at this time will be left and right
Visual plastic tube, internal water level are adjusted to the observation position apart from plastic tube upper port 100mm, in left and right visual plastic tube
Water level is tested in middle observation, is occurred leakage more serious at three during test, is handled in time, only with 5
Its time just carries out leak test test to five kilometers of drainage pipelines, it is ensured that engineering is handed over as scheduled as agreed, expense total more than 900
Member has saved expense, has obtained Party A's favorable comment.
Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
