Description of drawings
Fig. 1 is the structural representation of the measurement mechanism of a kind of ground settlement of the present invention.
Embodiment
Among Fig. 1, at first fills with water in communicating pipe 2 and connecting pipe 3 connects water storage cylinder 1 again, continues water filling, makes the water that certain depth is arranged in the water storage cylinder 1, then water surface displacement measuring device is fixed on the water storage cylinder 1.Generally measuring point n is installed in the place that land subsidence do not occur, if there is sedimentation also can measure with spirit-leveling instrument.Like this, if land subsidence has taken place in a certain measuring point or some measuring point, the water surface in the water storage cylinder 1 will change, because the draft of float 53 in water is certain, the variation of the water surface will drive wheel 52 and rotate the displacement of measuring float then by angular displacement sensor 51 in the water storage cylinder 1 so.According to the variation of each measuring point float 53 position, can calculate the settling amount of each measuring point with respect to measuring point n.The displacement of supposing measuring point 1, measuring point 2, measuring point n place float is respectively: h
C1, h
C2,, h
CnThen each measuring point with respect to the settling amount of measuring point n is respectively: h
C1-h
Cn, h
C2-h
Cn,, 0, if the actual settling amount of having surveyed out measuring point n with spirit-leveling instrument is h
N is heavy, the actual settling amount of each measuring point is respectively so: h
C1-h
Cn+ h
N is heavy, h
C2-h
Cn+ h
N is heavy,, h
N is heavySo just can calculate the actual settling amount of each measuring point.
Arrange altogether among Fig. 1 n measuring point has been installed, each measuring point all comprises: the support 56 of water storage cylinder 1, communicating pipe 2, connecting pipe 3, water 4, angular displacement sensor 51, wheel 52, float 53, counterweight 54, rope 55, angular displacement sensor.Communicating pipe 2, connecting pipe 3 are connected with water storage cylinder 1, the liquid phase of their inside is communicated with, float 53 is suspended on the water surface in the water storage cylinder 1, this float 53 has rope 55, the other end of this rope 55 connects counterweight 54, and this rope 55 also is connected with angular displacement sensor 51, this angular displacement sensor 51 is connected with the data transmission device (not shown), this data transmission device can be wired, also can be wireless data transmission device, the signal of angular displacement just can be sent to land subsidence data processing centre (DPC) by this data transmission device like this; This angular displacement sensor 51 is fixed on the water storage cylinder 1 by support 56, and float 53 and counterweight 54 are suspended on by a rope 55 on the wheel 52 of support 56, and when water surface site changed, rope 55 just can drive sensor 51 and rotate like this; This device also is equipped with the accumulator (not shown), and this accumulator is used for to angular displacement sensor 51 and data transmission device power supply.Wherein, the material of water storage cylinder 1, communicating pipe 2, connecting pipe 3 can be selected plastics, stainless steel, PVC or organic glass etc. for use, the material of float 53 is stainless steel, organic glass or aluminium alloy etc., and angular displacement sensor 51 is the angular transducer of conductive plastics angular displacement sensor, angular encoder or other types and principle.
In the process that land subsidence takes place, water surface site in each water storage cylinder 1 will change, float 53 will drive angular displacement sensor 51 and rotate, the variation of float 53 vertical heights has just reflected the size of each measuring point ground settlement, and its size can be calculated by the variation and angular displacement sensor 51 runner diameters of angular displacement sensor 51 output voltages.The actual settling amount of each measuring point is respectively: h
C1-h
Cn+ h
N is heavy, h
C2-h
Cn+ h
N is heavy,, h
N is heavy
Liquid in water storage cylinder also can be with the mixture replacing water of oil with water.
In measurement mechanism of the present invention, owing to adopted little and the displacement that angular displacement sensor 51 that sensitivity is very high is measured the water surface of driving torque, so the diameter that can be by changing angular displacement sensor 51 rotor wheels and the diameter of float 53 improve measuring accuracy; In addition, by support 56 is set, make the lifting of float 53 highly stable, the output valve of angular displacement sensor 51 is also highly stable, thereby guaranteed the accurate measurement of ground settlement; And be unattended in the whole measuring process, saved a large amount of workloads; And by wireless data transmission device, can be in real time with the data transmission of ground settlement to Ground Subsidence Monitoring control and management center.
