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
Being arranged at above pressurised water tank, the internal diameter of test specimen container matches with the external diameter of concrete sample and makes concrete sample close
Being sleeved in test specimen container, the bottom of the press water contact concrete sample in pressurised water tank, sensing conductor is placed in concrete examination
The top of part, sensing conductor connects power supply, pressurised water tank ground connection, and host computer is connected to sensing conductor and detects pressurised water tank and sensing
Whether conductor forms loop.
In order to make sensing conductor contact concrete sample upper surface closely, in order to timely when concrete sample seeps water
Forming loop, the present embodiment also includes pressuring flat device, and pressuring flat device is the weight that bottom surface matches with concrete sample end face, pressure
Leveling device is placed on sensing conductor and is pressed on concrete sample end face by sensing conductor.
In order to according to actual needs sensing conductor be carried out pressing process, the appearance that weight is hollow that the present embodiment uses
Device, adds in container and has the material of mobility to increase weight, and the material of tool mobility can use water, fine sand etc., and this is
In order to allow material uniformly bottom surface be exerted a force in container, prevent from exerting a force uneven cause sensing conductor can not Detection results by shadow
Ring.
In order to when concrete test block seeps water can formation loop promptly and accurately, sensing conductor is be woven into by conductor
Grid, 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 includes central authorities
Region and marginal area, middle section and marginal area are woven into by conductor and connect different power supplys, middle section respectively

Before on-test, on concrete, plane is without infiltration, now, from conductor grid lead-out wire and test specimen bottom compression water tank
It is mutually insulated that lead-out wire does not seep water due to concrete, does not i.e. form loop.When after on-test, at bottom tank pressure
The lower water of effect progressively permeates to concrete sample top, conductor grid lead-out wire and examination before water does not completely penetrate plane
Part bottom compression water tank lead-out wire is also insulation, only in water penetration to test specimen after plane, due to conductor grid and coagulation
Soil Anti-leakage instrument cover die inner concrete test specimen on plane all contact, now due to the electric action of water, conductor grid lead-out wire with
Test specimen bottom compression water tank lead-out wire is equivalent to connect.Draw with test specimen bottom compression water tank by gathering conductor grid lead-out wire
The on-state of line, 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 or conductive fabric for distinguishing infiltration
It is designed as the form such as Fig. 2, is divided into center circle region and the peripheral circles region of 2 mutually insulateds, draws wire respectively, if
Detecting at circle ring area and leak, computer sends, according to signal, the information of leaking, if at center circle region detection to infiltration,
Computer sends infiltration information according to signal area.
