Description
Technical field
The present invention relates to a kind of construction quality detection methods, more particularly to a kind of building wall anti-permeability performance detection side
Method.
Background technique
Concrete construction metope usually requires to carry out it surface anti-permeability performance detection, traditional detection after construction
Method is mainly using sampling experiment detection, i.e., under the multiple position cuttings of wall then sample carries out experiment detection, so not
A degree of destruction only will cause to wall, and detection time is longer.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of building wall anti-permeability performance detection methods, do not have to cutting
Sampling can quickly detect the anti-permeability performance of wall.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme:
A kind of building wall anti-permeability performance detection method, comprising the following steps: A, first setting one has row on concrete wall surface
The water inlet pipe of water valve, end face and the concrete wall surface of water inlet pipe fit closely water-tight；B, the pure water of certain volume is led to again
Magnetic force is crossed to be cut into after the active water of small molecule structure in the pressure injection water inlet pipe of 2-5MPA and to keep pressure 0.5-1 small
When；C, it is then shut off intake pressure and opens the drain valve on water inlet pipe and remaining water is collected and measures its volume；D, coagulation is chosen
Multiple points are averaged the penetration index for calculating concrete wall surface on cob wall face after repeating the above steps.A kind of building of the present invention
Metope anti-permeability performance detection method carries out high pressure activating water penetration by choosing concrete wall surface different location, and passes through measurement water
Situation of change is measured to calculate the penetration index of concrete wall surface, does not have to destroy wall, but also detection efficiency and standard when not only detecting
True property is very high, and the high pressure magnetism active water in the present invention is not only prepared simply, but also since it is small molecule water so permeability
By force, be conducive to achieve the effect that quickly to detect.
Preferably, the water inlet bore in the step A is 100-150 millimeters, it is ensured that the contact surface for detection of seeping water
Product.
Preferably, cutting magnetic force is generated by electromagnetic coil in the step B, it is easily operated.
Preferably, the magnetic induction intensity that the magnetic force in the step B is cut is 6000-8000 Gauss, it is ensured that cutting
The performance of active water out.
Preferably, the quantity of concrete wall surface measurement point is no less than 0.3 every square metre in the step D, it is ensured that
The validity of detection.
Compared with prior art, a kind of building wall anti-permeability performance detection method of the present invention the utility model has the advantages that passing through selection
Concrete wall surface different location carries out high pressure activating water penetration, and calculates concrete wall surface by measurement water situation of change
Penetration index does not have to destroy wall when not only detecting, but also detection efficiency and accuracy are very high, and this method is easy to operate, reliable
Property it is high, have great popularization value.
