Description

Technical Field

[0001] This utility model relates to the field of foundation pit water level detection technology, and in particular to a groundwater well dewatering water level measuring device. Background Technology

[0002] As buildings become taller, larger, and deeper, more and more underground structures are being constructed below the groundwater level, requiring dewatering of the foundation pit. The most common method for this is well dewatering. To ensure foundation pit safety and proper underground construction conditions, the groundwater level needs to be lowered to 0.5-1.0m below the foundation before construction can begin. However, from an environmental and water conservation perspective, the amount of groundwater pumped out should be minimized. To ensure foundation pit safety, groundwater level measurements must be conducted at very short intervals to monitor the water level dynamics. This requires real-time monitoring of the dewatering well water level and maintaining it within a certain range. Traditional methods of monitoring dewatering well water levels using measuring rods or tape measures are labor-intensive and cumbersome, while using dedicated instruments involves a large initial investment.

[0022] This embodiment discloses a groundwater well dewatering level measuring device, including a float 1 floating on the surface of the groundwater well 9, a telescopic rod 2 detachably installed on the float 1, a counterweight 4 installed at the bottom of the float 1, a scale bracket 5 installed at the wellhead of the groundwater well 9, and a scale 7 installed on the scale bracket 5 and parallel to the telescopic rod 2; wherein the telescopic rod 2 includes multiple plug-in rod units 21; from bottom to top, the outer diameter of each rod unit 21 on the telescopic rod 2 decreases sequentially; a reserved hole 51 is provided on the scale bracket 5 to facilitate the top of the telescopic rod 2 to pass through.

[0023] The bottom of the telescopic marker 2 is supported by the buoyancy of the float plate 1. Then, the indicator arrow 22 on the top of the telescopic marker 2, together with the scale 7 installed at the wellhead of the underground water pipe well 9, is used to indicate the water level in the underground water pipe well 9.

[0024] In this embodiment, the material of the float 1 is either polystyrene foam board or EPS foam board; the marker units 21 are all PVC pipes; specifically, they are designed to be lightweight for easy carrying; between each inserted marker unit 21, the bottom of the uppermost marker unit 21 fits and fits into the inner top of the lowermost marker unit 21, and the adjacent units are locked together by friction; in order to improve the connection strength, they can also be fixed by wrapping with waterproof tape.

[0025] In this embodiment, a connecting screw sleeve 11 is integrally designed at the top center of the float plate 1; the lower end of the connecting screw sleeve 11 is connected to the counterweight block 4 through the chain 3, and the upper end of the connecting screw sleeve 11 is threadedly connected to the bottom of the telescopic marker 2; wherein the counterweight block 4 is used to ensure the vertical state of the telescopic marker 2.

[0026] In this embodiment, an indicator arrow 22 is installed on the top of the telescopic rod 2 to accurately indicate the scale 7.

[0027] In this embodiment, a limiting sleeve 6 is installed on the scale bracket 5 and outside the reserved hole 51, and the scale 7 is inserted into the limiting sleeve 6; wherein the limiting sleeve 6 has a square groove that matches the outer diameter of the scale 7, and a locking member 61 for positioning the scale 7 is installed on the side wall of the limiting sleeve 6. Specifically, the locking member 61 is a bolt, which is used to lock and position the scale 7 inside the limiting sleeve 6 after the position height has been adjusted.

[0028] In this embodiment, when in use, a connecting screw sleeve 11 is integrally designed at the top center of the float 1 for threaded connection to the lower end of the telescopic marker 2.

[0029] First, the telescopic marker 2 is disconnected from the connecting screw sleeve 11 on the float plate 1; then, each marker unit 21 inside the telescopic marker 2 is extended in sequence. In practice, waterproof tape can also be wrapped around the connecting end of adjacent marker units 21; then, the bottom of the extended telescopic marker 2 is extended to the bottom of the underground water pipe well 9 to achieve the function of bottom probing, thereby adjusting the position height of the scale 7 in the limiting sleeve 6 and locking it.
