The utility model is characterized in that a pressure sensor (2) is arranged at the upper portion of the built-in hole, another monitoring instrument (8) is built-in the pressure sensor, a lower end cover (9) is arranged at the lower end of the pressure sensor, and the pipe wall and the lower end cover (9) of the pressure sensor are provided with a group of water penetration holes (6). The utility model has the beneficial effects the monitoring instrument can be selected for different mounting positions, the monitoring instrument in the pressure sensor is convenient for being replaced, the mounting position can be freely adjusted, after the performance of the monitoring instrument in the pressure sensor is changed, the parameters of the instrument can be readjusted, two monitoring instruments are combined, thus reducing the cost and improving the benefit.
Description
Technical field
The utility model relates to the hydraulic engineering monitoring device, especially a kind of safety monitoring assembly that is used for monitoring of gate dam seepage pressure and water level monitoring.
Background technology
At present, the installation method of gate dam safety monitoring instrument adopts method of directly burring more, promptly by being bored into projected depth, the safety monitoring instrument is directly put into projected depth, around the safety monitoring instrument, put into certain medium coarse sand, clay ball or bentonitic clay sealing of hole are adopted in top then, the advantage of this method is that directly the safety monitoring instrument is buried in boring underground, having cut off the safety monitoring instrument contacts with atmospheric pressure, therefore do not need instrument is carried out the atmospheric pressure correction, shortcoming is that instrument is difficult to change as if damaging, and makes this measuring point be in the no datat state like this, influences data globality and data analysis.
The utility model content
The purpose of this utility model is exactly to have the not easily changeable defective of gate dam safety monitoring assembly now in order to overcome, and a kind of gate dam safety monitoring assembly is provided, and this device is easy to use.
The technical scheme that its technical matters that solves the utility model adopts is:
The gate dam safety monitoring assembly, comprise pre-buried via hole, pre-buried via hole bottom is provided with filling material, be provided with monitoring instrument and continuous lead in the filling material, it is characterized in that: pre-buried via hole top is provided with a piezometric tube, be provided with monitoring instrument in the piezometric tube, the piezometric tube lower end is provided with bottom end cover, and piezometric tube tube wall and bottom end cover are provided with one group of infiltration hole.
Described monitoring instrument is the type vibration wire pore pressure gauge of the phreatic water pressure of present measurement, is called for short osmometer.The principle of osmometer is to obtain phreatic pressure by the hole on its gauge head, string wire by its inside draws Shen or shortening, then the physical quantity of La Shen or shortening is become frequency signal, detect this frequency signal, by conversion, just can obtain phreatic water pressure, this hydraulic pressure also can be converted into corresponding water level difference, just head value.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
Also wrap up geotextile on piezometric tube tube wall and the bottom end cover, geotextile also is provided with the fastening geotextile of copper wire outward.
Be provided with joint between adjacent two joint piezometric tube and connect, a piezometric tube is to be formed by connecting by joint by two joint piezometric tube.
Described one group of infiltration hole is two or more infiltrations holes.
Described infiltration hole is the plum blossom shape and arranges.
The beneficial effects of the utility model are can be at different installation position selection different monitoring instruments; Monitoring instrument in the piezometric tube is convenient to change, and the installation site can free adjustment; After monitoring instrument performance in the piezometric tube changes, can readjust instrument parameter; Two kinds of mounting meanss that monitoring instrument combines have reduced cost, have improved benefit.
Below in conjunction with drawings and Examples the utility model is further specified.
