Technical Field

[0001] This utility model relates to municipal water supply, and in particular to a multi-layer sealed water meter well structure with water guiding function. Background Technology

[0002] Municipal water supply refers to the process of drawing water from a water source, sending it through water pipelines to a water plant for water treatment, and then pressurizing the treated water before sending it to users through a distribution network. In order to facilitate the counting of users' water consumption, water meters need to be installed on the water pipes during municipal water supply. To protect the water meters, they are usually installed in water meter wells.

[0003] Existing water meter wells are generally installed underground. The installation method involves digging a pit on the ground, installing the integrated water meter well in the pit, and then covering the water meter well with a well cover. However, during rainfall, rainwater, groundwater, or leaking pipes may seep into the well through gaps in the well cover or loose joints, making the inside of the water meter well damp. After prolonged use, electrical equipment may be at risk of leakage. Utility Model Content

Detailed Implementation

[0032] 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.

[0033] Example 1: This example aims to propose a multi-layer sealed water meter well structure with water guiding function.

[0034] according to Figures 1-3 As shown, it includes a well pit, a prefabricated water meter well 8, a sealing layer, a water guiding structure, and a drainage layer.

[0035] The well is located on the ground, near the residence, and its opening faces upwards.

[0036] A drainage layer is laid at the bottom of the pit. The drainage layer includes a foundation layer 3, a drainage trough 9, and a drainage outlet 15. The foundation layer 3 is located at the bottom of the pit, and the drainage outlet 15 is located on the foundation layer 3. In this embodiment, the foundation layer 3 is constructed by concrete pouring, and the drainage outlet 15 is vertically arranged and connected to the external drainage system.

[0037] The finished water meter well 8 is set on the foundation layer 3. The finished water meter well 8 is covered with a well cover 4. The drainage channel 9 is opened at the bottom of the finished water meter well 8. The drainage channel 9 contacts the foundation layer 3 and forms a drainage cavity that communicates with the drainage outlet 15.

[0038] A backfill layer is provided in the pit to fill the gap between the finished water meter well 8 and the inner wall of the pit. The backfill layer includes a backfill soil layer 1 and a protective layer 2. The backfill soil layer 1 is set in the pit to fill the gap between the finished water meter well 8 and the inner wall of the pit. The protective layer 2 is laid on top of the backfill soil layer 1 and is flush with the top of the pit. In this embodiment, the protective layer 2 can be made of concrete.

[0039] The sealing layer is placed inside the protective layer 2 and is used to seal the gap between the well cover 4 and the backfill layer.

[0040] The sealing layer includes a first sealing layer and a second sealing layer. The first sealing layer is located above the second sealing layer, and both the first and second sealing layers are disposed within the backfill layer. The first sealing layer is dynamically sealed to the well cover 4, and the second sealing layer is statically sealed to the well cover 4.

[0041] The first sealing layer includes a first sealing groove 11 and a sealing ring 12. The first sealing groove 11 is disposed at the contact surface between the protective layer 2 and the manhole cover 4. The first sealing groove 11 is an annular groove structure, and the opening direction of the first sealing groove 11 faces the manhole cover 4. The sealing ring 12 is fixedly sleeved on the outer side of the manhole cover 4. In this embodiment, the sealing ring 12 can be made of rubber to fill the gap inside the first sealing groove 11. When the manhole cover 4 is placed downwards, the sealing ring 12 is compressed. When the sealing ring 12 moves to align with the first sealing groove 11, the sealing ring 12 returns to its original position and fills the inside of the first sealing groove 11.

[0042] The second sealing layer includes a second sealing groove 13 and an injection port 14. The second sealing groove 13 is located at the contact surface between the protective layer 2 and the well cover 4. The second sealing groove 13 is located below the first sealing groove 11. The second sealing groove 13 is connected to the outside through the injection port 14. The injection port 14 is used to inject adhesive into the interior of the second sealing groove 13. In this embodiment, the adhesive material can be polyurethane potting compound or silicone sealant. The liquid adhesive is injected into the second sealing groove 13 and then waited for it to solidify to achieve a static seal between the first sealing groove 11 and the well cover 4.

[0043] The water guiding structure is set inside the backfill layer. The water guiding structure includes a diversion channel and a drainage cavity. The drainage cavity is located below the sealing layer and is connected to the drainage layer through the diversion channel. The water guiding structure includes a water guiding trough 16 and a water guiding pipe 10. The water guiding trough 16 is set at the contact surface between the protective layer 2 and the finished water meter well 8. The opening direction of the water guiding trough 16 is opposite to that of the finished water meter well 8. The bottom of the water guiding trough 16 is provided with a water guiding pipe 10. The water guiding trough 16 is connected to the drainage cavity through the water guiding pipe 10 to form a safety redundancy. After the water penetrates the sealing layer, the water guiding structure guides the water into the drainage layer for rapid drainage, preventing the water from accumulating and causing the sealing layer to become damp and rotten.

[0044] The finished water meter well 8 is used for the passage of urban water supply pipes. The water supply pipe is equipped with control elements, which are located inside the finished water meter well 8. The control elements include a remote water meter 5, a pre-meter locking valve 6, and a post-meter steel valve 7. The remote water meter 5, the pre-meter locking valve 6, and the post-meter steel valve 7 are all installed on the water supply pipe, and the pre-meter locking valve 6, the remote water meter 5, and the post-meter steel valve 7 are arranged sequentially along the water supply direction.

[0045] This allows for the formation of a multi-layered sealing structure, enhancing the sealing performance of the water meter well. Simultaneously, the water is guided through the water-conducting structure, preventing a small amount of water from seeping in and accumulating at the multi-layered sealing points, thus avoiding prolonged contact between the sealing structure and the accumulated water, which would cause the sealing structure to become damp and rotten.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
