Detailed description of the invention
Seeing Fig. 1, the present embodiment includes pressurised water tank, test specimen container, sensing conductor, power supply and host computer,
Test specimen container is arranged at above pressurised water tank, and the internal diameter of test specimen container matches with the external diameter of concrete sample
And make concrete sample be sleeved on closely in test specimen container, the press water contact concrete in pressurised water tank
The bottom of test specimen, sensing conductor is placed in the top of concrete sample, and sensing conductor connects power supply, pressurised water tank
Ground connection, host computer is connected to sensing conductor and detects whether pressurised water tank forms loop with sensing conductor.
In order to make sensing conductor contact concrete sample upper surface closely, in order to ooze at concrete sample
Forming loop during water in time, the present embodiment also includes pressuring flat device, and pressuring flat device is that bottom surface is tried with concrete
The weight that part end face matches, pressuring flat device is placed on sensing conductor and sensing conductor is pressed in concrete
On test specimen end face.
In order to sensing conductor carries out pressing process according to actual needs, the weight that the present embodiment uses is
The container of hollow, adds in container and has the material of mobility to increase weight, and the material of tool mobility is permissible
Using water, fine sand etc., this is to allow material exert a force bottom surface uniformly in container, preventing force
Uneven cause sensing conductor can not Detection results impacted.
In order to when concrete test block seeps water can formation loop promptly and accurately, sensing conductor is by conductor
The grid being woven into, mesh shape matches with concrete sample top shape.
For the ease of differentiating infiltration for concrete water-permeating or test specimen edge because poorly sealed leaks, grid
It is woven into by conductor including middle section and marginal area, middle section and marginal area and connects respectively
Different power supplys, is separated by insulator between middle section and marginal area, and host computer is respectively connecting to
Whether middle section and marginal area form loop with detection pressurised water tank with middle section or marginal area.
This method for sensing, comprises the following steps:
First concrete sample is arranged in the test specimen container of upper and lower opening and concrete sample holds with test specimen
Being formed between device and seal, test specimen container is divided into pressurised water tank, is above set sensing conductor, sensing conductor and pressure (hydraulic) water
Pressure (hydraulic) water in case the most directly contacts the upper and lower surface of concrete sample, then sensing conductor is connect power supply,
Pressurised water tank ground connection, if host computer connects sensing conductor with whether shape between detection sensing conductor and pressurised water tank
Become loop；
Then pressurised water tank provides pressure (hydraulic) water, treats that water corrodes the sensing conductor to upper surface through concrete test block
Time formed loop, upper computer detection is formed to loop, and records pressurised water tank pressure, as concrete examination
The anti-permeability performance of block.
Before on-test, on concrete, plane is without infiltration, now, bottom conductor grid lead-out wire with test specimen
It is mutually insulated that pressurised water tank lead-out wire does not seep water due to concrete, does not i.e. form loop.Work as test
After beginning, under the tank pressure effect of bottom, water progressively permeates to concrete sample top, the completeest at water
Before entirely penetrating into plane, conductor grid lead-out wire is also insulation with test specimen bottom compression water tank lead-out wire,
Only in water penetration to test specimen after plane, due to conductor grid and concrete impervious instrument cover die inner concrete
On test specimen, plane all contacts, now due to the electric action of water, bottom conductor grid lead-out wire and test specimen
Pressurised water tank lead-out wire is equivalent to connect.By gathering conductor grid lead-out wire and test specimen bottom compression water tank
The on-state of lead-out wire, can sense the infiltration situation of test specimen.
See Fig. 2, be that test specimen peripheral sealing the most sternly leaks or test specimen infiltration, conductor grid for distinguishing infiltration
Or conductive fabric is designed as the form such as Fig. 2, it is divided into center circle region and the peripheral circles of 2 mutually insulateds
Region, draws wire respectively, if detecting at circle ring area and leaking, computer sends leakage according to signal
Water information, if at center circle region detection to seeping water, computer sends infiltration information according to signal area.
