Description

Technical Field

[0001] This utility model relates to the field of water-stop curtain technology, and in particular to a water-stop curtain used in the process of groundwater extraction and treatment. Background Technology

[0002] During groundwater extraction, a water-stop curtain is a continuous seepage prevention structure used to block the flow of groundwater inside and outside the foundation pit. It is usually formed by processes such as cement-soil mixing piles, high-pressure jet grouting piles, or underground continuous walls, which can effectively reduce the impact of precipitation on the surrounding environment and ensure construction safety.

[0003] The existing water-stop curtain structure is relatively simple. After it is cast, it is easy for the water-stop curtain to become skewed due to the collapse of the foundation pit. When the curtain is skewed, it will lose its water-blocking effect, and it is also difficult to detect the collapse of the foundation pit in real time. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a water-stop curtain for groundwater extraction and treatment processes, thereby solving the aforementioned problems.

A base plate overlaps the top surface of the foundation pit body, with an installation hole through the top surface of the base plate. A base is fixedly connected to the top surface of the base plate, with a limiting groove on the top surface of the base. A limiting slider is slidably connected to the inner wall of the limiting groove. A threaded rod is rotatably connected to the inner wall of the base, and the threaded rod is threadedly connected to the inner wall of the limiting slider. A connecting mechanism is provided on the top surface of the limiting slider. An internal support assembly and a detection mechanism are provided above the foundation pit body. A driving assembly is provided on the front of the base.

[0006] Preferably, the connecting mechanism consists of a fixed sleeve, a fixed shaft, and a connecting plate. The fixed sleeve is fixedly connected to the top surface of the limiting slider, the fixed shaft is fixedly connected to the inner wall of the fixed sleeve, and the connecting plate is fixedly connected to the right side of the fixed shaft.

[0007] Preferably, the inner support assembly consists of a limiting shaft, a limiting disc, an inner support plate, and a spring. The limiting shaft is slidably connected to the inner wall of the connecting plate. The limiting disc is fixedly connected to the left side of the limiting shaft. The inner support plate is fixedly connected to the right side of the limiting shaft and overlaps with the surface of the water-stop curtain. The spring is fixedly connected to the right side of the connecting plate and to the left side of the inner support plate.

[0008] Preferably, the detection mechanism consists of a contact sensor and a detection plate. The contact sensor is fixedly connected to the left side of the connecting plate, the inner wall of the detection plate is fixedly connected to the surface of the limiting plate, and the detection plate overlaps with the detection end of the contact sensor.

[0009] Preferably, the drive assembly consists of a servo motor, a drive wheel, a transmission belt, and a driven wheel. The servo motor is fixedly connected to the front of the base, the inner wall of the drive wheel is fixedly connected to the output end of the servo motor, the transmission belt meshes with the inner wall of the drive wheel, and the inner wall of the driven wheel is fixedly connected to the surface of the threaded rod, and the inner wall of the driven wheel meshes with the transmission belt.

[0010] Preferably, the base is rectangular and made of metal.

[0011] Preferably, there are multiple limiting shafts, and the multiple limiting shafts are symmetrically arranged with the vertical center line on the right side of the connecting plate as the axis of symmetry.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The water-stop curtain used in the groundwater extraction process is first cast into the foundation pit body. Anchor nails are used to fix the base plate on top of the foundation pit body using mounting holes. The drive assembly is activated to drive the threaded rod to rotate. Through the threaded connection between the threaded rod and the limit slider, the limit slider, connecting mechanism and internal support assembly are driven to move to the left to support the water-stop curtain. When the water-stop curtain tilts, the thrust generated by the tilt drives the internal support assembly and detection mechanism to move to the right. When the detection mechanism makes contact inside, the collapse status of the foundation pit body can be monitored and alarmed. This achieves the goal of facilitating the support of the water-stop curtain and facilitating real-time monitoring of the foundation pit's collapse status, greatly improving the flexibility of the water-stop curtain and its water-blocking stability.
