Abstract
Description
Technical Field
[0001] This utility model relates to the field of dewatering well technology, and in particular to a dewatering well anti-fall safety protection cover assembly. Background Technology
[0002] Currently, for engineering construction projects in areas with abundant groundwater and varying water levels, the impact of groundwater on construction safety is significant, especially during the excavation of foundation pits. Dewatering wells play a crucial role in construction, effectively lowering the groundwater level to ensure excavation and foundation construction proceed under dry conditions. This not only prevents adverse phenomena such as water inrush, mudslides, and frost heaving in the foundation pit but also increases slope stability, guaranteeing both construction safety and progress.
[0003] In the construction industry, during most earthwork excavation stages, the construction of dewatering projects often involves the use of conventional dewatering wells. However, on construction sites, exposed dewatering wells often lack protective covers and are located within temporary roads, making it inconvenient for vehicles to pass through. This is especially true in narrow sections of the construction road, where the construction road is particularly important and poses significant safety risks.
[0004] To address the land occupation issues and safety risks associated with dewatering wells, a concealed dewatering well fall-prevention safety cover was designed. This cover not only prevents accidental falls of personnel or objects but also conceals and buries dewatering pipes and cables, ensuring unobstructed road surfaces, facilitating vehicle access on temporary roads, expanding the work area at the construction site, and enhancing the image of safe and civilized construction. Utility Model Content
[0005] The purpose of this utility model is to provide a safety cover assembly for preventing falls from existing dewatering wells, in order to solve the aforementioned problems of land occupation and safety risks associated with existing dewatering wells.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A safety cover assembly for preventing falls from dewatering wells includes a concrete layer and a dewatering pipe well embedded in the concrete layer. A fall prevention mechanism for comprehensive protection of the upper end of the dewatering pipe well is provided between the dewatering pipe well and the upper end of the concrete layer. A concealed conduit structure for concealed cable and pipe routing is provided between the dewatering pipe well and the side of the concrete layer.
[0008] As a further description of the above technical solution:
[0009] The fall protection mechanism includes a well ring embedded in the concrete layer and covering the upper end of the dewatering pipe well, a cover plate that is rotatably installed on the upper end of the well ring via a hinge, a fall protection wire mesh that is detachably installed between the well ring and the hinge, and a safety buckle structure set between the well ring and the cover plate.
[0010] As a further description of the above technical solution:
[0011] A flexible rubber shock-absorbing pad is filled between the inside of the well ring and the outside of the dewatering pipe well.
[0012] As a further description of the above technical solution:
[0013] A polyethylene isolation plate is installed between the outside of the well ring and the concrete layer.
[0014] As a further description of the above technical solution:
[0015] The safety buckle structure includes a safety buckle fixed on the end of the cover plate away from the hinge and a safety catch fixed on the outside of the well ring and engaged with the safety buckle.
[0016] As a further description of the above technical solution:
[0017] The lower end of the cover plate is integrally fixedly connected to a limiting ring that transitions with the upper opening of the well ring, and a cross-shaped reinforcing rod is integrally fixedly connected between the lower end of the cover plate and the limiting ring.
[0018] As a further description of the above technical solution:
[0019] The underground pipe structure includes a pre-embedded PVC sleeve that is horizontally and vertically connected to the side of the dewatering well and located inside the concrete layer, a dewatering pipe that passes through the pre-embedded PVC sleeve and is located between the concrete layer and the dewatering well, and a water pump cable that passes through the pre-embedded PVC sleeve and is located between the concrete layer and the dewatering well.
[0020] As a further description of the above technical solution:
[0021] A switch box is installed above the concrete layer, and the output end of the switch box is electrically connected to the input end of the water pump cable.
[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0023] 1. In this utility model, an anti-fall mechanism is added to the original dewatering well. The anti-fall mechanism consists of a well ring, a cover plate, and an anti-fall net. It prevents falling accidents due to damage to the cover plate. The well ring with integrated bent flanges can be pressed down by concrete to ensure the stability of the anti-fall mechanism. In addition, the polyethylene isolation plate can effectively isolate the concrete, and the anti-fall safety cover plate can be reused, saving resources and costs.
[0024] 2. In this utility model, by setting a pre-embedded PVC sleeve on the dewatering pipe well, the occurrence of the dewatering pipe well and the anti-fall mechanism falling under the pressure on the concrete road surface can be reduced. At the same time, the pre-embedded PVC sleeve facilitates the concealed installation of dewatering pipes and various cables, making the road surface unobstructed. This not only prevents people or objects from falling accidentally, but also increases the working area for construction. After completion, the overall road surface looks neat and orderly, improving the image of safe and civilized construction. Attached Figure Description

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a safety protection cover assembly for preventing falls from dewatering wells, including a concrete layer 11 and a dewatering pipe well 16 embedded in the concrete layer 11. A fall prevention mechanism for comprehensive protection of the upper end of the dewatering pipe well 16 is provided between the upper end of the dewatering pipe well 16 and the concrete layer 11. A concealed pipe structure for concealed cable and pipe routing is provided between the dewatering pipe well 16 and the concrete layer 11 on the side.
[0031] Specifically, such as Figure 1 and Figure 2As shown, the fall protection mechanism includes a well ring 6 embedded in the concrete layer 11 and covering the upper end of the dewatering pipe well 16, a cover plate 1 rotatably installed on the upper end of the well ring 6 via a hinge 5, a fall protection wire mesh 8 detachably installed between the well ring 6 and the hinge 5, and a safety buckle structure set between the well ring 6 and the cover plate 1.
[0032] The space between the inside of the well ring 6 and the outside of the dewatering pipe well 16 is filled with a flexible rubber shock-absorbing pad 7, which can fill and seal the gap between the well ring 6 and the dewatering pipe well 16 to ensure the stability of the protective cover assembly installed on the dewatering pipe well 16. A polyethylene isolation plate 9 is set between the outside of the well ring 6 and the concrete layer 11 to prevent the concrete of the concrete layer 11 from sticking to the outer wall of the well ring 6, which can reduce the workload and difficulty of removing the protective cover assembly later.
[0033] Specifically, such as Figure 1 and Figure 2 As shown, the safety buckle structure includes a safety buckle 3 fixed on the end of the cover plate 1 away from the hinge 5 and a safety buckle 10 fixed on the outside of the well ring 6 and engaged with the safety buckle 3. This can reduce the occurrence of problems such as lateral displacement and shaking of the cover plate 1 on the well ring 6, thereby improving the safety and stability of the cover plate 1 after it is closed.
[0034] Specifically, such as Figure 1 and Figure 2 As shown, a limiting ring 2 is integrally fixedly connected to the lower end of the cover plate 1, which is in transition fit with the upper opening of the well ring 6. After the cover plate 1 is closed on the well ring 6, the occurrence of problems such as lateral displacement and shaking of the cover plate 1 under force can be reduced. A cross-shaped reinforcing rod 4 is integrally fixedly connected between the lower end of the cover plate 1 and the limiting ring 2 to enhance the structural strength, bending resistance and impact resistance of the cover plate 1.
[0035] Specifically, such as Figure 1 and Figure 2 As shown, the underground pipe structure includes a pre-embedded PVC sleeve 12 that is horizontally and vertically connected to the side of the dewatering manhole 16 and located inside the concrete layer 11, a dewatering pipe 13 that passes through the pre-embedded PVC sleeve 12 and is located between the concrete layer 11 and the dewatering manhole 16, and a water pump cable 14 that passes through the pre-embedded PVC sleeve 12 and is located between the concrete layer 11 and the dewatering manhole 16. A switch box 15 is installed above the concrete layer 11. The output end of the switch box 15 is electrically connected to the input end of the water pump cable 14. The output end of the water pump cable 14 is connected to the water pump located in the dewatering manhole 16. By operating the switch box 15 on the concrete layer 11, the power supply to or from the water pump can be controlled, thereby realizing the pumping control operation of the dewatering manhole 16.
[0036] Working principle: First, according to the construction drawings of the dewatering project, the dewatering wells are laid out and positioned, the dewatering wells are driven into the ground and sand-free dewatering pipe wells 16 are installed, the wells are washed, and dewatering filter material is backfilled around them; Second, the top elevation of the dewatering pipe well 16 is determined using a level, and the height of the dewatering pipe well 16 is set to be about 5cm lower than the cover plate 1. A pre-embedded PVC sleeve 12 with a diameter of 200mm is installed on the side wall of the dewatering pipe well 16. The dewatering pipe 13 and the water pump cable 14 are installed and concealed in the pre-embedded PVC sleeve 12. Then, the fall protection mechanism is fixedly installed. After the well ring 6, the cover plate 1, and the fall protection wire mesh 8 are fixed, a polyethylene isolation plate 9 is installed around the well ring 6, which is bent into an integrated flange. Finally, concrete is poured, and after the concrete is smoothed, compacted, and cured, a concrete layer 11 is formed, thus completing the construction of the buried dewatering well fall protection safety protection component.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
