Abstract
Description
Technical Field
[0001] This utility model relates to the field of groundwater level monitoring technology in building engineering, and more specifically, to a water level monitoring device for anti-buoyancy reserved wells. Background Technology
[0002] Anti-buoyancy reserved wells are structures used for drainage and buoyancy reduction during the construction phase to prevent building structures from floating due to groundwater buoyancy. In traditional dewatering operations using anti-buoyancy reserved wells, the wellhead cover is typically directly equipped with pumping holes, but this has the following drawbacks: real-time water level monitoring is impossible, requiring frequent opening of the cover for inspection, which is cumbersome and poses safety hazards; dewatering operations lack data support, easily leading to over-pumping or insufficient dewatering, affecting construction safety and costs. Therefore, there is an urgent need for a simple, convenient real-time water level monitoring device. Utility Model Content
[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a water level monitoring device for anti-buoyancy reserved wells.
[0004] A water level monitoring device for an anti-buoyancy reserved well includes a well cover body, wherein the well cover body is provided with a pumping hole and a guide hole; the pumping hole is used to pass through a pumping pipe, and the guide hole is used to install a guide pipe;
[0005] A buoyancy scale assembly is inserted through the guide tube. The buoyancy scale assembly includes a buoyancy block floating on the liquid surface, a scale rod connected to the top of the buoyancy block, and a limiting block located at the top of the scale rod. The buoyancy block drives the scale rod to rise and fall with the liquid level inside the guide tube.
[0006] Furthermore, the guide tube is fixed to the guide hole of the manhole cover body.
[0007] Furthermore, the lower end of the guide tube extends below the manhole cover body, while the upper end extends above the manhole cover body.
[0008] Furthermore, the outer wall of the scale rod is provided with graduation lines.
[0009] Furthermore, the limiting block is threadedly connected to the top of the ruler rod.
[0010] Furthermore, the guide tube is a PVC pipe.
[0011] Furthermore, the inner diameter of the guide tube is larger than the outer diameter of the scale rod.
[0012] Furthermore, the water extraction hole is also equipped with a sealing ring to prevent groundwater leakage.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This anti-buoyancy reserved well water level monitoring device features graduated lines on the outer wall of the scale rod of its buoyancy scale assembly. The water level of the anti-buoyancy reserved well can be directly obtained by reading the scale value of the scale rod exposed above the well cover, without the need for auxiliary equipment or opening the well cover itself. This allows for real-time monitoring of the water level within the well. Furthermore, reading the water level without opening the well cover simplifies the operation process, avoids the cumbersome process of frequently opening the well cover, and reduces the risk of items accidentally falling into the well after the cover is opened.
[0015] Furthermore, this anti-buoyancy reserved well water level monitoring device converts water level changes into the displacement of a scale rod through the principle of buoyancy, enabling real-time observation of the water level without opening the well cover; the device has a simple overall structure and is easy to operate.
[0016] Furthermore, this anti-buoyancy reserved well water level monitoring device is made of materials such as PVC, and has a simple structure and is easy to install and maintain. Moreover, the anti-buoyancy reserved well water level monitoring device provided in this embodiment can obtain the water level value in the anti-buoyancy reserved well in real time, so as to determine whether to continue pumping based on the actual situation of groundwater level and prevent excessive pumping.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figures 1-4 As shown, this embodiment provides an anti-buoyancy reserved well water level monitoring device, including a well cover body 1 covering the reserved well opening. The well cover body 1 is provided with a pumping hole 11 and a guide hole 12; the pumping hole 11 is used to pass through a pumping pipe 2, and the guide hole 12 is used to install a guide pipe 3. The guide pipe 3 is vertically arranged at the guide hole 12, and a buoyancy scale assembly 4 passes through the guide pipe 3. The buoyancy scale assembly 4 includes a buoyancy block 41 floating on the liquid surface 5, a scale rod 42 connected to the top of the buoyancy block 41, and a limiting block 43 located at the top of the scale rod 42; the buoyancy block 41 drives the scale rod 42 to rise and fall with the liquid level in the guide pipe 3.
[0029] In this embodiment, the guide tube 3 is fixed to the guide hole 12 of the manhole cover body 1. The lower end of the guide tube 3 extends into the lower part of the manhole cover body 1, and the upper end of the guide tube 3 extends above the manhole cover body 1. This facilitates the insertion of the buoyancy gauge assembly 4, and the portion of the guide tube 3 extending downwards from the manhole cover body 1 can prevent the buoyancy gauge assembly 4 from tilting, thus preventing excessive deviation in liquid level measurement.
[0030] In the buoyancy scale assembly 4 of this embodiment, the outer wall of the scale rod 42 is provided with scale lines 421. Through the scale lines 421 exposed above the manhole cover body 1, the water level value in the anti-buoyancy reserved well can be directly observed and read. The structure is simple and convenient for observation.
[0031] In this embodiment, the buoyancy gauge assembly 4 has a limiting block 43 connected to the gauge rod 42 at a position near the top of the manhole cover body 1. This prevents the buoyancy gauge assembly 4 from falling into the anti-buoyancy reserved well when the water level is too low. The limiting block 43 can be fixedly connected to the gauge rod 42 or threadedly connected to the gauge rod 42.
[0032] In this embodiment, more specifically, the guide tube 3 is made of PVC pipe, and the inner diameter of the guide tube 3 is larger than the outer diameter of the ruler rod 42; when the buoyancy block 41 is a cube, the inner diameter of the guide tube 3 is 5mm-10mm smaller than the side length of the buoyancy block 41; when the buoyancy block 41 is spherical, the inner diameter of the guide tube 3 is 5mm-10mm smaller than the diameter of the buoyancy block 41.
[0033] The ruler rod 42 is made of lightweight, corrosion-resistant PVC material.
[0034] In this embodiment, the manhole cover body 1 is also provided with a sealing ring at its water extraction hole 11 to prevent groundwater leakage.
[0035] The anti-buoyancy reserved well water level monitoring device provided in this embodiment utilizes a graduated buoyancy scale assembly 4 to visually monitor the water level of the anti-buoyancy reserved well, allowing real-time observation of the water level without opening the well cover. Specifically, the buoyancy block 41 of the buoyancy scale assembly 4 floats on the liquid surface 5, rising and falling synchronously with the water level in the well, driving the scale rod 42 connected to its top to move vertically up and down within the guide tube 3. The graduation lines 421 on the side wall of the scale rod 42 rise and fall with the rod. By directly reading the graduation value of the scale rod 42 above the well cover body 1, the water level data in the anti-buoyancy reserved well can be obtained in real time.
[0036] To prevent the buoyancy gauge assembly 4 from tilting, the two ends of the guide tube 3 extend upward and downward to the well cover body 1 respectively, ensuring that the gauge rod 42 can move up and down along the fixed, vertically arranged guide tube 3; the limiting block 43 is set at the top of the gauge rod 42 to prevent the buoyancy gauge assembly 4 from falling into the well when the water level is too low.
[0037] The anti-buoyancy reserved well water level monitoring device provided in this embodiment has scale lines 421 arranged on the outer wall of the scale rod 42 of the buoyancy scale assembly 4. The water level value of the anti-buoyancy reserved well can be directly obtained by reading the scale value of the scale rod 42 exposed above the well cover body 1. No other auxiliary equipment is required, and the well cover body 1 does not need to be opened to achieve real-time monitoring of the water level in the well. In addition, when reading the water level value in the well, it is not necessary to open the well cover body 1, which not only simplifies the operation process, but also avoids the cumbersome operation caused by frequently opening the well cover body 1, and reduces the risk of items accidentally falling into the well after the well cover body 1 is opened.
[0038] The anti-buoyancy reserved well water level monitoring device provided in this embodiment converts water level changes into displacement of the scale rod 42 through the principle of buoyancy, enabling real-time observation of the water level without opening the well cover body 1; the overall structure of the device is simple and can be directly modified from existing well covers.
[0039] The anti-buoyancy reserved well water level monitoring device provided in this embodiment is made of PVC and other materials, with a simple structure and convenient installation and maintenance. Furthermore, the anti-buoyancy reserved well water level monitoring device provided in this embodiment can obtain the water level value in the anti-buoyancy reserved well in real time, thereby determining whether to continue pumping based on the actual situation of the groundwater level and preventing excessive pumping.
[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
