Cable displacement sensor soil settlement detector

Release date: July 1, 2019 Hits: 125

At present, in the soft soil foundation treatment project, the design drawings require that the foundation treatment process should be monitored and detected, and the effect of soft foundation treatment should be tested by this means. The layered settlement monitoring is one of the key monitoring contents. The layered settlement monitoring mainly monitors the layered compression of each pre compressed soil layer in the whole soft foundation treatment process, evaluates the reinforcement effect, and calculates the consolidation degree of each soil layer. Therefore, the accuracy and accuracy of settlement value is very important to the implementation of the whole project.

The traditional observation method is to embed the settlement magnetic ring and the matching layered pipe in the middle of the treatment area, and use the special steel ruler settlement meter to measure and read. This method not only has high labor intensity and low work efficiency, but also has large numerical error of manual measurement, which has a great impact on the effect of soft foundation treatment.

Specific implementation mode

Please refer to figure 1, an electrical pull rope soil settlement detector, which includes a reader 1, a rope displacement sensor 2, a metal settlement tube 3, a steel wire rope 4 and a settlement ring 5; the reading 1 obtains the signal of the rope displacement sensor 2 according to the set parameters, and converts it into the corresponding displacement value for display; The upper end of the steel wire rope 4 is connected with the pulling rope displacement sensor 2, and the lower end penetrates into the metal settlement pipe 3; two symmetrical long grooves are arranged along the direction parallel to the center line on the pipe section corresponding to the soft soil layer 6 of the metal settlement pipe 3; The settlement ring 5 is set on the metal settling pipe 3, and a connecting plate is arranged along the radial direction on the settlement ring 5. The connecting plate is arranged in the two symmetrical long grooves and connected with the steel wire rope 4.

The measurement accuracy of the cable displacement sensor 2 is 0.1 mm. The power supply of the reader 1 is used to supply power to itself and also to supply power to the rope displacement sensor 2; The wire rope displacement sensor 2 forms a settlement deformation unit with metal settlement tube 3, steel wire rope 4 and settlement ring 5. The settlement 3 is connected with the pulling rope displacement sensor 2 through the steel wire rope 4, and the linear displacement of the settlement ring 5 is transmitted to the pulling rope displacement sensor 2 through the steel wire rope 4, which is converted into a transmissible electrical signal. The electric reading device 1 reads the pulling rope displacement sensor 2 The cable displacement sensor 2 fully combines the advantages of angle sensor and linear displacement sensor, and is a sensor with small installation size, compact structure, large measuring stroke and high precision, and its stroke ranges from several hundred mm to more than ten meters.

The pulling rope displacement sensor is composed of a stretchable stainless steel wire rope wrapped on a threaded wheel hub, which is connected with a precise rotation sensor. Its function is to convert mechanical movement into electrical signals that can be measured, recorded or transmitted. The metal settlement pipe 3 passes through the soft soil layer 6 and is inserted into the underlying hard soil layer 7 to provide support for the steel wire rope 4 and the settlement ring 5; The settlement ring 5 is embedded in the soft foundation and moves synchronously with the soil deformation, which is a moving part. The movement reflected by the settlement ring 5 is the compression deformation of the soil, that is, the settlement deformation of the soil layer 6. The settlement deformation is transmitted to the pull rope displacement sensor synchronously through the steel wire rope 4. The inner circle of the settlement ring 5 rubs with the metal settling tube 3, so the inner circle of the settlement ring 5 is required to be smooth to reduce the friction.

The advantages and positive effects are as follows: the linear displacement of settlement ring is converted into measurable angle value with the core of tension rope displacement sensor, and then reduced to high-precision settlement value after calculation. The accurate measurement of each layer of soft foundation can be realized by using multiple rope displacement sensors, which can provide reliable data for engineering progress; The electric measuring technology can easily realize the reading of numerical value, can replace the heavy manual measurement work, has high measurement efficiency, can save a lot of manpower and material resources, and avoid manual measurement error; moreover, the utility model is easy to operate, the core components can be recycled and reused, and the manufacturing cost is low.
