Description

Technical Field

[0001] This utility model relates to the field of foundation pit engineering construction technology, specifically to a groundwater level monitoring device used in foundation pit engineering construction. Background Technology

[0002] Foundation pit engineering involves deep foundation pit excavation, which can easily disrupt the original stratum balance, leading to changes in groundwater seepage and potentially causing safety hazards such as instability of the support structure, collapse of the pit wall, or subsidence of the surrounding surface. Groundwater level monitoring devices are key equipment for foundation pit safety management. By collecting real-time dynamic data on groundwater, they provide a scientific basis for adjusting construction parameters, optimizing dewatering measures, and providing risk warnings. The accuracy and real-time performance of these devices directly affect the efficiency of engineering decision-making and the level of safety control. Typically, groundwater level monitoring devices are integrated by connecting a water level gauge probe and a water level terminal to monitor groundwater levels in real time and transmit data information.

[0003] In practical applications, existing integrated groundwater level monitoring devices generally expose their water level terminals directly to the construction environment without effective protection measures. The complex environment of the foundation pit construction site, frequent operation of mechanical equipment, and earthwork loading and compression can easily damage the exposed water level terminals, causing not only interruption of monitoring data and affecting the real-time early warning function, but also significantly increasing the frequency and cost of equipment maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a groundwater level monitoring device for foundation pit construction, in order to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A groundwater level monitoring device for foundation pit construction includes a water level pipe, a connecting plate, a water level gauge probe, and a water level terminal. The water level pipe is buried inside the soil, the connecting plate is fixed in the soil by anchors, the water level gauge probe and the water level terminal are connected by a cable, the water level gauge probe is located inside the water level pipe, the bottom of the water level terminal is detachably inserted into the inside of the water level pipe, and a protective component is provided on the top of the connecting plate.

[0007] Furthermore, the protective assembly includes a cover plate, docking blocks, and a silicone buffer pad. The bottom of the cover plate is fitted to the top of the connecting plate.

[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0025] Example 1, as Figures 1 to 7 As shown, a groundwater level monitoring device for foundation pit construction includes a water level pipe 1, a connecting plate 2, a water level probe 3, and a water level terminal 4. The water level pipe 1 is buried inside the soil, the connecting plate 2 is fixed in the soil by anchors, the water level probe 3 and the water level terminal 4 are connected by a cable, the water level probe 3 is located inside the water level pipe 1, the bottom of the water level terminal 4 is detachably inserted into the inside of the water level pipe 1, and a protective component 5 is provided on the top of the connecting plate 2.

[0026] Specifically, the protective component 5 includes a cover plate 501, a docking block 502, and a silicone buffer pad 503. The bottom of the cover plate 501 is attached to the top of the connecting plate 2. There are four docking blocks 502 arranged in a rectangular array on the top of the connecting plate 2 and fixedly connected to the top of the connecting plate 2. The bottom of the cover plate 501 has four docking slots 504 arranged in a rectangular array. The four docking blocks 502 are respectively docked with the four docking slots 504. The top of the water level terminal 4 is located inside the cover plate 501. The silicone buffer pad 503 is fixedly installed on the top of the inner wall of the cover plate 501 and its bottom is attached to the top of the water level terminal 4.

[0027] In use, the water level pipe 1 is first buried in the hole pre-drilled in the soil. Then, the installation groove for the connecting plate 2 and the protective component 5 is further drilled on the top of the soil. This ensures that after the protective component 5 is installed, the top of its cover plate 501 is flush with the top of the soil, so that the position of the cover plate 501 remains as stable as possible during the movement of equipment on the construction site, reducing the impact of sinking on the water level terminal 4. In addition, a sealing gasket (not shown in the figure) is set at the connection between the water level terminal 4 and the water level pipe 1, which can protect the connection between the water level pipe 1 and the water level terminal 4. The cover plate 501 can be installed by connecting the docking groove 504 and the docking block 502. At this time, the bottom of the silicone buffer pad 503 inside the cover plate 501 is in contact with the top of the water level terminal 4.

[0028] Example 2 is a further improvement on Example 1, and is as follows: The interior of each of the two docking blocks 502 has two movable slots 6 that are symmetrically distributed front and back. The interior of each of the two movable slots 6 on the same side has a spring 7 fixedly installed. The two springs 7 in the two movable slots 6 on the same side are fixedly connected to the opposite sides of each other with a plug-in block 8. The interior of the cover plate 501 has four plug-in slots 9 that are evenly distributed. The side of the four plug-in blocks 8 away from the corresponding spring 7 is plugged into the four plug-in slots 9 one by one.

[0029] With this configuration, when installing the cover plate 501, the plug-in blocks 8 located on both the front and rear sides are first manually slid towards the center, causing a portion of the plug-in blocks 8 to extend beyond the mating block 502 and retract. After the cover plate 501 is installed, the plug-in blocks 8 are released, and under the action of the spring 7, the plug-in blocks 8 retract into the mating block 502 and re-insert into the plug-in groove 9. Through the cooperation between the plug-in blocks 8 and the plug-in groove 9, the connection between the cover plate 501 and the mating block 502 is strengthened, ensuring protection of the water level terminal 4. In addition, grooves are provided on the top of each plug-in block 8, which can drive the plug-in blocks 8 to move (this is a technical means that can be easily obtained by those skilled in the art, so it is not shown and will not be described in detail).

[0030] Example 3 is a further improvement based on Example 2. Specifically, the top of the cover plate 501 is provided with four evenly distributed protective grooves 10. Each of the four protective grooves 10 contains a rubber plug 11. The protective grooves 10 are connected to the movable groove 6.

[0031] This design, with the rubber plug 11 installed inside the protective groove 10, restricts the insertion block 8. Only by removing the rubber plug 11 during subsequent maintenance can the insertion block 8 be moved, further improving safety during use.

[0032] Example 4 is a further improvement on Example 2, and it is as follows: There are eight springs 7, which are distributed in pairs inside the four moving slots 6.

[0033] This configuration strengthens the pushing effect on the plug-in block 8 through multiple springs 7, thereby making the connection between the plug-in block 502 and the cover plate 501 tighter.

[0034] Example 5 is a further improvement on Example 1, and its specific details are as follows: the anchor is an expansion bolt, and the connecting plate 2 is fixedly connected to the soil by the expansion bolt.

[0035] This configuration, achieved through expansion bolts, enhances the stability of the connecting plate 2 after installation, ensuring the long-term usability of the subsequent protective components 5.

[0036] Example 6 is a further improvement based on Example 1. Specifically, the water level terminal 4 has an external thread on its bottom outer side and an internal thread on the inner wall of the top opening of the water level pipe 1 that matches the external thread on the bottom outer side of the water level terminal 4. The water level terminal 4 is screwed into the water level pipe 1 through the thread.

[0037] This configuration strengthens the connection between the water level terminal 4 and the water level pipe 1, thereby maintaining stability during use after the water level terminal 4 is installed.

[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
