Abstract
The invention discloses a method for detecting wall leakage, and belongs to the technical field of civil engineering. The method comprises the following steps of: sealing the surface of a wall on which a leakage point occurs; injecting a highly volatile liquid substance into the leakage point with a needle tube after sealing; then resealing the leakage point; and finally, slowly moving a volatilesubstance detector on another wall of the same wall corresponding to the sealed wall, trapping a gas formed by the volatile substance and determining a leakage source and a leakage passage through the prompting of the detector. The method has the advantages of conveniently and accurately finding out the leakage source and the leakage passage on the wall, solving the problem that the leakage source is difficult to determine and bringing convenience to the subsequent maintenance work, and is easy to operate and convenient to implement.
Description
Technical field
The present invention relates to a kind of method that detects the construction wall seepage, belong to technical field of civil engineering.
Background technology
In the construction work product, the seepage phenomenon is a kind of common defective.And the seepage phenomenon often can not in time be found in work progress, and what have may just be found after using considerable time, seriously affects people's production and life.And, after seepage appears in building products, often present the state of " three not clear ", namely the origination point agnogenio, seepage of seepage is not clear, leak path is not clear, and this has caused difficulty to maintenance process.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art part, the invention provides a kind of method that detects the body of wall seepage, the principle of utilizing volatilization gas to be caught by instrument can make things convenient for, find accurately leak source and the leak path of body of wall.
The present invention is achieved through the following technical solutions:
A kind of method that detects the body of wall seepage comprises the steps:
The metope face seal that breakthrough at first will occur.
After the sealing, in breakthrough, inject volatile liquid substance with needle tubing, and then seal breakthrough.
At last, on the another side metope of the same body of wall corresponding with the envelope wall face, slowly move at this metope with the volatile substance detecting instrument, catch the gas that volatile substance forms, determine leak source and leak path by the prompting of detecting instrument.
Described encapsulating method is to seal with wax.
Described volatile liquid substance is alcohol.
Described volatile substance detecting instrument is alcohol content tester.
Principle of the present invention is:
Some volatile substances can volatilize in air at normal temperatures, become gas as alcohol, freon etc. from liquid, when gas is in restrained condition, can seeks passage and distribute.If inject these volatile substances in a part of body of wall, and with the decanting point sealing, the gas of this volatile substance will be sought outlet along body of wall slit passage.And these gases can detect, and special detecting instrument is all arranged, and find the position of gas by instrument, have also just found leak source and the leak path on the body of wall.
The invention has the beneficial effects as follows: utilize volatile substance to become the characteristic of gas at normal temperatures, diffusion by gas and to the detection of gas, can make things convenient for, find accurately leak source and leak path on the body of wall, solved the difficult problem that leak source is difficult to determine, for follow-up maintenance job has brought facility; Simple to operate, be convenient to implement.
Embodiment
The present invention is further described below in conjunction with embodiment.
A kind of method that detects the body of wall seepage comprises the steps:
1, the metope surface that breakthrough at first will occur seals with wax, and the body of wall of common buildings should seal interior metope, and the body of wall in pond generally should seal wall face.
2, behind the sealing metope, in breakthrough, inject alcohol with needle tubing, and then seal breakthrough.
3, last, carry out slow mobile capture alcohol gas with the CA2000 alcohol content tester at the metope of body of wall another side, the body of wall of common buildings should detect wall face, and the body of wall in pond generally should detect interior metope.Determine leak source and leak path by the prompting of alcohol content tester.When the alarm of alcohol content tester is rung somewhere, just can determine the position of leak source, when having many places to ring, just explanation has the many places leak source.
After detecting leak source and leak path, can carry out maintenance process then with mark on the drawing with coloured chalk.
Above-mentioned steps can be cooperated by two people be finished, and the metope operation of breakthrough is appearring in a people, finishes two steps of front, then, is detected at another side metope accordingly by another people.
Body of wall of the present invention not only refers to vertically disposed body of wall, also comprise be horizontally disposed with or be obliquely installed body of wall, as long as adopted the technical scheme identical with method disclosed by the invention essence all to fall within the protection domain of the present invention.
The volatile liquid substance that adopts is alcohol preferably; Also can be with other volatile liquid materials such as freon, but during practical application, response environment and personal safety do not work the mischief, should illegal relevant laws and regulations.
Claims (4)
1. a method that detects the body of wall seepage is characterized in that: comprise the steps:
(1) the metope face seal of breakthrough at first will appear;
(2) after the sealing, in breakthrough, inject volatile liquid substance with needle tubing, and then seal breakthrough;
(3) last, on the another side metope of the same body of wall corresponding with the envelope wall face, slowly move at this metope with the volatile substance detecting instrument, catch the gas that volatile substance forms, determine leak source and leak path by the prompting of detecting instrument.
2. the method for detection body of wall seepage according to claim 1, it is characterized in that: described encapsulating method is to seal with wax.
3. the method for detection body of wall seepage according to claim 1 and 2, it is characterized in that: described volatile liquid substance is alcohol.
4. the method for detection body of wall seepage according to claim 3, it is characterized in that: described volatile substance detecting instrument is alcohol content tester.
