Technical Field

[0001] The utility model relates to the technical field of settlement monitoring, in particular to a ground settlement stratification in-situ monitoring device. Background Art

[0002] Ground subsidence is one of the most important environmental geological problems in my country at present, and excessive groundwater exploitation is an important factor leading to ground subsidence. Surface subsidence affects the construction and maintenance of various infrastructures. Severe ground subsidence has caused varying degrees of damage to infrastructure such as drainage facilities, water supply pipelines, and subways, bringing adverse effects on industrial and agricultural production and people's lives. When carrying out foundation pit dewatering construction in urban building complexes, in order to ensure the safety of existing buildings and underground pipelines and other facilities outside the foundation pit, it is necessary to ensure that the groundwater level outside the foundation pit does not drop within the allowable safety range. Once the groundwater level drops below the safety line, the foundation pit dewatering is immediately stopped or groundwater is recharged outside the foundation pit to ensure the safety of existing buildings. Under the premise of controlling the development of ground subsidence, it is very important to establish an integrated device for ground subsidence and foundation pit water level monitoring in order to rationally utilize groundwater resources.

[0003] The existing Chinese patent with announcement number CN219141813U discloses a ground settlement monitoring device, including a weight block, a support frame, a horizontal plate, perforations, a ruler, an indicator plate and scale lines. Two support frames are symmetrically fixedly connected on both sides of the horizontal plate. A plurality of first vertical rods are longitudinally penetrated and slidably sleeved on the horizontal plate. The top ends of the plurality of first vertical rods are commonly fixedly connected to the first horizontal plate, and the rotating handle drives the second threaded vertical rods to rotate.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the device is installed, the weight block lacks limiting measures, and under the influence of gravity, it will sink into the mud inside the foundation pit to increase resistance, which is not conducive to the adjustment of the position of the device and needs to be improved; therefore, a ground subsidence stratification in-situ monitoring device is proposed to address the above problems.
