Description
Technical field
The utility model is related to a kind of uplift force measuring device, specifically refers to a kind of Uplift than surveying device.
Background technology
Uplift pressure, builds technics, refers to the infiltration in building and its ground, calculates certain level the uplift pressure in section
With osmotic pressure sum.The uplift pressure of water retaining structure is that the seepage field formed under the effect of upstream and downstream net water head is produced, and is
The load that hydrostatic pressure derives from.Uplift pressure is a vertical upward power, and it reduces gravity dam and acts on ground
Effective pressure, so as to reduce the skid resistance at dam bottom.Meanwhile, uplift pressure is also produced in dam body, so as to have impact on answering in dam body
Power is distributed.Because uplift pressure has very great influence, it is necessary to be monitored to Uplift, then to the stability of the dam foundation
Each concrete dam can install uplift force measuring device.

Ring flange is attached by connecting screw rod.
The inventor of present patent application has found when stating the uplift force measuring device of two kinds of structures in actual use, the first
The measurement apparatus of structure employ the double pipe structure of standpipe and monitoring tube side-by-side, although manpower comparing surveys relatively convenient, but increases
A pipe and corresponding joint, the space that device takes when installing are bigger, and holistic cost is higher, while the structure of device becomes
Many, resistance to overturning declines；Other whole device does not account for corrosion problem, easily corrosion after use time is long.And the
The uplift force measuring device of two kinds of structures often occurs following problem during prolonged and repeated use：1st, instrument cable is clipped in
Under the influence of long-term instrument deadweight, easily there is downward sliding phenomenon, cause measured value to be forbidden.2nd, upper lower flange connecting screw rod is long-term
In dam foundation gallery wet environment, easily getting rusty disconnected phenomenon of even becoming rusty occur.3rd, sensor ageing damage must more emat sensor must
Upper flange device must be opened, conventional flange disk size is largerOperation is wasted time and energy.4th, manpower comparing is surveyed
Port lid cap is irony material, in gallery wet environment, is easily got rusty, and occurs stubborn phenomenon for a long time.
In sum, a kind of structure is lacked at present to simplify, is difficult corrosion and leak, installed and easy to maintenance, manpower comparing is surveyed
When noiseless is worked to automatic measurement, the longer Uplift of service life is than surveying device.
