Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings:
As shown in Figure 1, 2, the device based on the absorptive test xoncrete structure packing of concrete, is used for including one
The main frame of detection water is contained, described main frame is closely connected with concrete structural surface to be measured;The top of the main frame is provided with one
Control system, control system include miniature electronic water pump, control valve and meter, and miniature electronic water pump is connected with water source, passes through
Water pipe suppresses water in the cavity of main frame, is in series with control valve and watermeter gauge, in described main frame on described water pipe
On be additionally provided with precision pressure gauge 10, the pressure in main frame is detected.
By adopting said apparatus, can scene and the dense state for testing indoor test concrete structural surface, the detection
The detection method that device is adopted belongs to non-destructive testing method, and concrete surface nothing is damaged, and has quick, convenient, accurate, little
Ingeniously, the advantages of easy to operate, the quantization of concrete surface state-detection is appropriate to, is commented with the construction quality that obtains xoncrete structure
Valency, and can be used to evaluate the homogeneity of concrete structure construction.
Main frame is fixed on concrete structural surface by the screw rod with nut, and by the embedded hard rubber circle of main frame with mixed
Xtah Crude Clay structure surface is closely connected.
The number at least two of screw rod, because cannot be fixed to main frame well using a screw rod, certainly may be used
To be fixed to main frame using multiple screw rods;The signal carried out according to 3 shanks of bolt in accompanying drawing.
Main frame can select the cylinder type hollow cavity of internal diameter 80mm, height 40mm;The sky of other shapes can also be selected
Chambers of the heart body, when main frame is for circular cylindrical cavity structure, screw rod is arranged along its circumferencial direction, and the spacing between multiple screw rods should
It is uniform, being preferably fixed to main frame, when for rectangle, screw rod can be separately positioned on four angles of rectangle
On.
Although the shape of main frame is unrestricted, the shape being to try to using comparison rule, it is easy to enter the volume of cavity
Row is calculated and is demarcated.
