Description

Technical Field

[0001] This utility model relates to the field of drainage well technology, and in particular to an easy-to-maintain anti-buoyancy drainage well for basements. Background Technology

[0002] Basement anti-buoyancy drainage wells are engineering facilities designed for underground structures (such as basements, underground garages, sunken plazas, etc.). They are primarily used to lower the groundwater level, balance buoyancy, ensure structural stability against buoyancy, and solve drainage problems in underground spaces. Through active or passive drainage, they reduce the buoyancy effect of groundwater on the structural foundation slab, preventing the building from floating, cracking, or even being damaged due to buoyancy. During underground engineering construction, wellpoint dewatering is generally used, placed around the foundation pit and within the basement area, to lower the groundwater level to 500mm below the foundation slab, ensuring that there is no water in the foundation pit during construction.

[0003] Conventional drainage wells are equipped with a filter layer to filter out sand, gravel, or other impurities from the groundwater. However, because the filter layer is fixed in place, it is not convenient to remove it for cleaning or maintenance when it becomes clogged. Utility Model Content

[0004] The purpose of this utility model is to provide an easy-to-maintain anti-buoyancy drainage well for basements, which solves the problem that conventional drainage wells have a filter layer installed inside to filter out sand or other impurities in the groundwater. However, since the filter layer is fixedly installed, it is inconvenient to remove it for cleaning or maintenance when it becomes clogged.

[0005] To achieve the above objectives, this utility model provides a basement anti-buoyancy drainage well that is easy to maintain, including a well body, a pump suction mechanism, and a reinforcement device. The pump suction mechanism is installed on the well body, the reinforcement device is installed on the well body, and a filtration device is also included. The filtration device includes an installation ring, a coarse filter screen, a fine filter screen, a ring plate, a support plate, and a telescopic assembly. An installation groove is provided on the inner side of the well body. The ring plate is fixedly installed on the installation ring. The support plate is slidably installed on the ring plate through the telescopic assembly and is located in the installation groove. The coarse filter screen is fixedly installed in the installation ring, and the fine filter screen is fixedly installed in the installation ring and close to the coarse filter screen.

[0006] The telescopic assembly includes a telescopic rod and a telescopic spring. The two ends of the telescopic rod are fixedly connected to the mounting ring and the support plate, respectively. The telescopic spring is sleeved on the telescopic rod and located between the mounting ring and the support plate.

[0007] The well body also includes a ladder and a platform. The ladder is fixedly installed inside the well body, and the platform is fixedly installed inside the well body and close to the mounting slot.

[0008] The reinforcement device includes a counterweight base and an anchoring assembly. The counterweight base is fixedly installed on the outside of the well body and has a counterweight groove. The anchoring assembly is installed on the counterweight base.

[0009] The anchoring assembly includes a mounting plate and an anchor rod, wherein the mounting plate is fixedly mounted on the counterweight seat, and the anchor rod is fixedly mounted on the mounting plate.

[0010] This utility model discloses an easy-to-maintain anti-buoyancy drainage well for basements. In use, the well body is installed inside a well hole. The anchor rod is constructed using concrete, and concrete is poured into the counterweight groove within the counterweight base to ensure the well body's self-weight. The pump mechanism draws groundwater out of the well body, reducing the buoyancy of groundwater on the basement floor. Simultaneously, the coarse and fine filter screens within the mounting ring filter sand, gravel, and other impurities from the groundwater. When blockage occurs, workers enter the well body via a ladder and stand on the platform. By sliding the support plate closer to the mounting ring, the telescopic rod and telescopic spring retract, disengaging the support plate from the mounting groove on the well body. The mounting ring can then be removed for flushing or inspection, facilitating maintenance. Attached Figure Description

Detailed Implementation

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] The embodiment of this application is as follows:

[0018] Please see Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of a basement anti-buoyancy drainage well that is easy to maintain, according to this utility model. Figure 2 This is a schematic diagram showing the connection between the well body and the ladder of this utility model. Figure 3 This is a schematic diagram of the structure of the filtration device of this utility model.

[0019] This utility model provides a basement anti-buoyancy drainage well that is easy to maintain: it includes a well body 101, a pump suction mechanism 102, and a reinforcement device, and also includes a filter device. The filter device includes an installation ring 103, a coarse filter screen 104, a fine filter screen 105, a ring plate 106, a support plate 107, and a telescopic assembly. The telescopic assembly includes a telescopic rod 109 and a telescopic spring 110. The well body 101 also includes a ladder 111 and a platform 112. The reinforcement device includes a counterweight 113 and an anchoring assembly. The anchoring assembly includes an installation plate 115 and an anchor rod 116. The aforementioned solution solves the problem that conventional drainage wells have a filter layer to filter out sand or other impurities in the groundwater, but the filter layer is fixedly installed, making it inconvenient to remove for cleaning or maintenance when it becomes clogged.

[0020] In this embodiment, the telescopic component allows the support plate 107 to slide against the ring plate 106, thereby facilitating the detachment of the support plate 107 from the mounting groove 108 on the well body 101 and making it easier to remove the mounting ring 103 from the well body 101 for maintenance.

[0021] The well body 101 has an inner mounting groove 108. The annular plate 106 is fixedly mounted on the mounting ring 103. The support plate 107 is slidably mounted on the annular plate 106 via the telescopic assembly and is located within the mounting groove 108. The coarse filter screen 104 is fixedly mounted within the mounting ring 103, and the fine filter screen 105 is fixedly mounted within the mounting ring 103, close to the coarse filter screen 104. The well body 101 has a segmented structure, consisting of an inspection section, a filtration section, and a water collection section from top to bottom. Each section is fixedly connected by flange bolts. The well body 101 is made of fiberglass. The pump suction mechanism 102 consists of a water pump and pipes. The ring plate 106 is welded to the outside of the mounting ring 103. The inside of the ring plate 106 is turned inward. The coarse filter screen 104 is located below the fine filter screen 105. There are six sets of support plates 107 and telescopic components, which are arranged in a ring outside the mounting ring 103. When the filter screen is clogged, the worker enters the well body 101 and, with the cooperation of the telescopic components, pushes the support plate 107 to one side of the mounting ring 103, so that the support plate 107 disengages from the mounting groove 108 on the well body 101, thereby removing the mounting ring 103 from the well body 101 for flushing or repair, thus facilitating maintenance.

[0022] Secondly, the two ends of the telescopic rod 109 are fixedly connected to the mounting ring 103 and the support plate 107, respectively; the telescopic spring 110 is sleeved on the telescopic rod 109 and located between the mounting ring 103 and the support plate 107. The telescopic rod 109 is composed of two rod-shaped structures that can extend and retract with each other. The axis of the telescopic spring 110 coincides with the telescopic rod 109. Through the elastic force of the telescopic spring 110, the support plate 107 maintains a tendency to move outward, so that the support plate 107 can be inserted into the mounting groove 108.

[0023] Furthermore, the ladder 111 is fixedly installed inside the well body 101; the platform 112 is fixedly installed inside the well body 101 and close to the mounting groove 108. The ladder 111 is fixed inside the well body 101 by screws, and the platform 112 is located below the ladder 111. The arrangement of the ladder 111 and the platform 112 facilitates workers to safely descend into the well body 101.

[0024] Furthermore, the counterweight seat 113 is fixedly installed on the outside of the well body 101, and the counterweight seat 113 is provided with a counterweight groove 114; the anchoring assembly is installed on the counterweight seat 113, and the counterweight seat 113 is fixed to the bottom side of the well body 101 by screws. By pouring concrete into the counterweight groove 114 in the counterweight seat 113, the self-weight of the well body 101 is increased, and under the anchoring action of the anchoring assembly, the well body 101 is further prevented from floating.

[0025] Finally, the mounting plate 115 is fixedly installed on the counterweight seat 113; the anchor rod 116 is fixedly installed on the mounting plate 115. There are six sets of both the mounting plate 115 and the anchor rod 116, which are arranged in a ring at the bottom of the counterweight seat 113. The bottom end of the anchor rod 116 is bent upward to increase the gripping force of the anchor rod 116. By pouring concrete at the anchor rod 116, the gripping force of the counterweight seat 113 can be increased.

[0026] In this embodiment, during use, the well body 101 is installed inside the well hole, the anchor rod 116 is cast with concrete, and concrete is poured into the counterweight groove 114 within the counterweight seat 113 to ensure the self-weight of the well body 101. The pump mechanism draws groundwater out of the well body 101, reducing the buoyancy of the groundwater on the basement floor. Simultaneously, the coarse filter 104 and fine filter 105 within the mounting ring 103 can remove sand from the groundwater. The filter removes stones and other impurities. When a blockage occurs, a worker enters the well body 101 via the ladder 111 and stands on the platform 112. By sliding the support plate 107 toward the mounting ring 103, the telescopic rod 109 and the telescopic spring 110 retract. At this time, the support plate 107 disengages from the mounting groove 108 on the well body 101, allowing the mounting ring 103 to be removed for flushing or repair, thus facilitating maintenance.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
