Problems solved by technology

[0003] As the fine particles in the landslide mass migrate with the groundwater, they will be enriched in the hydrological wells. When the enrichment is too much, the channel between the hydrological wells and the landslide mass will be blocked, forming stagnant water, and it is difficult to reflect the groundwater level in time.

Abstract

The invention discloses a simple hydrological-hole dredging device. The simple hydrological-hole dredging device comprises a first dieselized pumping machine, a second dieselized pumping machine and a stirrer. The first dieselized pumping machine is connected with hard plastic pipes and used for pumping out underground water at the bottom of a hydrological hole. The second dieselized pumping machine is connected with soft plastic pipes and used for injecting water into the hydrological hole. The stirrer comprises a thin rope and a metal rod. The thin rope is connected with one end of the metal rod. A cloth strip or a sponge is arranged at the other end of the metal rod and used for stirring the underground water in the hydrological hole. According to the simple hydrological-hole dredging device, circulating of the water in the hydrological hole is achieved through the two dieselized pumping machines; and as the underground water in the hydrological hole is stirred through the stirrer, the hole dredging efficiency is greatly improved, and the hole dredging time is shortened. The simple hydrological-hole dredging device is simple in structure and convenient to install, and can be repeatedly used.

Description

technical field [0001] The invention relates to a desilting device, in particular to a simple hydrological hole cleaning device. Background technique [0002] Groundwater monitoring is a very important part of landslide monitoring. Combined with surface displacement monitoring, it is helpful to deeply understand the deformation mechanism of landslides and predict the stability of landslides under the action of reservoir water ups and downs and rainfall. Groundwater monitoring is different from surface displacement monitoring. Because the hydrological holes are located underground, it is difficult to guarantee the construction quality, and it is also difficult to find out whether they are blocked or silted up. Their influence is large and the way of influence is hidden, which seriously affects the reliability of monitoring data. If the construction is carried out strictly according to the design, the sedimentation of hydrological holes is an important factor affecting groundw...
