[0002] In the construction industry, whether it is civil buildings, industrial buildings, or integrated pipe gallery facilities, they all involve the use of underground space. Groundwater is relatively abundant in most parts of my country, and the high groundwater level has brought certain obstacles to the construction of foundation projects. Therefore, lowering the groundwater level in areas rich in groundwater is a prerequisite for foundation construction. During the foundation pit dewatering process, real-time monitoring of the groundwater level is also a top priority.

[0003] In areas with high groundwater content, precipitation wells are usually arranged around the foundation pit for precipitation. In the existing technology, the groundwater level is generally observed directly in the precipitation well, or the observation technology and observation equipment are complex and costly. In the former, since the precipitation of the pipe well around the foundation pit is carried out in a funnel shape with the precipitation well as the center, it is difficult to accurately measure the groundwater level in the construction area of ​​the foundation pit by directly observing the groundwater level in the precipitation well. The latter is difficult to become the choice for observing groundwater levels in most construction projects due to its high cost. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-2 As shown, the utility model provides a technical solution: a detachable simple groundwater level observation device, which is used to detect the groundwater level, including: a shell structure and a detection structure, the detection structure is arranged on the shell structure, and is used to detect the groundwater level.

[0026] like Figure 3 As shown, the shell structure includes a pointed conical end 1, the pointed conical end 1 has a diameter of 40 mm and a wall thickness of 2.5 mm, and is used to be connected to the bottom of the device so that the device can be smoothly inserted into the ground, a filter tube body 2 is arranged on the pointed conical end 1, and a filter hole is opened on the filter tube body 2. The filter tube body 2 is used to use the filter hole to infiltrate groundwater into the inside of the device. The filter hole diameter is smaller than the wall thickness of the steel pipe, and the vertical spacing of the filter holes is 1.5 times, which is used to allow groundwater to infiltrate into the inside of the shell structure, and an extension tube body arranged on the filter tube body 2. 3. The extension tube body 3 is used to extend the length of the entire device, and the measuring tube body 4 is arranged on the extension tube body 3. The top of the measuring tube body 4 is hollowed out to ensure that the scale 7 can move up and down freely. The pointed cone end 1, the filter tube body 2, the extension tube body 3 and the measuring tube body 4 are all connected by threaded connection, which is very convenient when the device needs to be lengthened. The shell structure is used to extend the device deep underground. The shell structure is assembled by threaded connection, and the shell structure is hollow, which is convenient for lengthening during use.

[0027] like Figure 4As shown, the detection structure includes a stainless steel filter 5 arranged on the detection structure, the stainless steel filter 5 is located at the connection between the filter tube body 2 and the extension tube body 3, the stainless steel filter 5 is used to filter the overflowing groundwater, and a reading unit arranged on the detection structure for reading the value, the reading unit includes a floating block 6 arranged on the detection structure, the floating block 6 has a diameter of 33mm and a height of 100mm, the floating block 6 is a cylindrical foam block, the size of the cylinder matches the size of the inner side of the shell structure, and a scale 7 arranged on the floating block 6 for displaying the reading, the scale 7 is provided with a scale for displaying the groundwater level, the size of the scale 7 is 5mm in diameter and 1.5mm in wall thickness, and the reading is displayed on the ground. After the sewage is filtered through the stainless steel filter 5, after the float 6 contacts the groundwater, it is affected by the buoyancy and drives the scale 7 to move up and down following the water level. After the movement stabilizes, the value on the scale 7 is read to complete the work of detecting the groundwater level, which is convenient for reading accurate values. A scale is set on the scale 7, and there are two reading methods. The first measurement method is to calculate the groundwater level height through the change of the scale 7 reading.
