A pit sensor sealer

Abstract

The invention discloses a measuring pit sensor sealer, which includes a sensor sealing tube, a positioning flange, an outer high neck sealing cover, an inner high neck sealing cover and a sealing flange. The sensor sealing tube crosses the concrete wall poured into the measuring pit. Inside, there are two positioning flanges, which are respectively located on both sides of the concrete wall to fix the sensor sealing tube; the outer high neck sealing cover and the inner high neck sealing cover are installed on the sensor seals on the corridor side and the pit side through threads respectively. There are two sealing flanges on the pipe, which are installed on the outside of the outer high-neck sealing cover and the inside of the inner high-neck sealing cover. The joint between the sensor wire and the sealing flange is equipped with an anti-leakage watertight head. The invention can form two layers of waterproofing on both sides of the wall, and the sensor sealing tube can protect the sensor wires from damage caused by drilling and excavation of the surrounding soil. At the same time, the rubber gasket at the watertight head can avoid damage to the sensor wires due to uneven settlement of the soil. The resulting tension and compression damage. It has simple structure and strong practicality.

Description

technical field [0001] The invention relates to a sensor sealer for measuring pits. Multiple sensor wires can be buried in the wall as required, and sealing flanges are installed on the water-facing surface of the test pit and the corridor wall of the sealer to form two waterproof layers, which can prevent water from leaking into the corridor and reduce soil settlement Impact on sensor devices. It belongs to the fields of hydraulic engineering and agronomy. Background technique [0002] Soil sensors are very popular in the world to detect soil properties or soil information such as soil moisture, salinity, temperature, pH, and soil tension, and transmit the collected real-time parameters to computer terminals through network construction in the test field. . In the process of carrying out relevant experimental research, in order to bury different types of soil sensors at different stages according to the growth of crops, it is usually necessary to dig out the soil profile...

AI Technical Summary

Problems solved by technology

There are at least three deficiencies in the method of burying the soil sensor in this way. The first is that after the wall is excavated by punching and drilling and a plurality of sensor wires are buried, the leakage channel of soil moisture in the test pit increases, and the sealing of the wall after backfilling is not strong. , the inner wall of the corridor is prone to water seepage; second, when a new soil sensor needs to be buried in the nearby soil, the re-drilling of the impact drill can easily damage the adjacent sensor; third, due to the low bearing capacity of the soft soil foundation, it is easy to deform after loading. As a result, the soil sensor buried in it is damaged due to uneven settlement, which affects the accuracy of the experiment
