Description
Technical Field
The utility model relates to a ground water level control technical field especially relates to a drilling ground water level real-time supervision device.
Background
Landslide geological disasters are serious geological disasters in the world, and cause serious threat and loss to human society. However, China is one of the most seriously affected countries by landslide disasters due to the factors of wide breadth of operators, complex terrain, variable climate and the like. Therefore, the landslide is necessarily monitored in all directions, and the underground water level and the water pressure are important parameters for analyzing the stability of the landslide. Groundwater level monitoring is an important part of landslide monitoring.
At present, the common drilling underground water level monitoring has two modes of automatic instrument monitoring and manual monitoring. The automatic monitoring instrument mainly comprises a float-type underground water level meter and a pressure-type underground water level meter. The manual monitoring mode has the defects of single monitoring content, poor timeliness due to the fact that information reporting mainly depends on the traditional telephone and letter modes. The automatic monitoring has the advantages of intellectualization, high precision, convenient use, capability of realizing real-time monitoring of the underground water level and the like. By adopting the automatic monitoring and automatic transmission technology, the automatic monitoring capability and the modernization level of the underground water are comprehensively improved, so that the automatic monitoring technology has important significance in monitoring the underground water level in real time.
However, the existing underground water level monitoring instrument and device have many problems, the existing monitoring device can be provided with a filter outside a sleeve of the monitoring instrument in order to avoid the influence of the existence of sand and silty clay in water on the accuracy of the monitoring data of the water pressure sensor, but the filter is found to be blocked in the actual using process. Once the filter is blocked, the data monitored by the water pressure sensor has a large error with the actual data.
In addition, heavy rainfall in a short time is the most common and common natural cause of landslide, so that landslide underground water level monitoring during rainfall is very necessary. However, in the actual monitoring process, it is found that the surface water during rainfall does not normally seep under the daily condition, but seeps from the soil body on the upper part of the drill hole too fast, at the moment, a pond effect is formed in the drill hole, and the water level in the drill hole is higher than the real underground water level. And the infiltration flow of the water is increased during rainfall, various fine substances doped when the water is infiltrated into the holes are increased, and meanwhile, the water in the drill holes is stirred to become turbid due to the increase of the infiltration flow. At this time, the density of the water body also needs to be considered after various impurities and dissolved substances are mixed into the water body. Therefore, the water pressure measured by the water pressure sensor will be distorted, and the finally calculated water level will also be distorted.
The power supply of the existing monitoring device mainly adopts two modes of solar power supply and battery power supply. In an area with short sunshine time or poor sunshine condition, the solar power supply device often has insufficient electric quantity and stops working. Neither of these two methods can feed back the device power to the remote monitoring center. The monitoring device stops working, and the remote monitoring center cannot determine whether the electric quantity of the monitoring device is exhausted or not in time. Once the monitoring device stops working due to power supply exhaustion, the monitoring work cannot be carried out in real time.
