DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-2 The utility model is further described in detail.

[0020] A centralized water meter controls the gate valve well, such as Figure 1-2 As shown, this embodiment includes a cylindrical reinforced concrete wall foundation well body 1, a main input water pipe 2, a main output water pipe 3, a four-way joint 4, a transition water pipe 5, a well cover 6, a user pipeline 7, a user gate valve 8 and a user water meter 9.

[0021] In this embodiment, both upper and lower ends of the cylindrical reinforced concrete wall foundation well body 1 are open. The cylindrical reinforced concrete wall foundation well body 1 is set in a corresponding underground pit. The upper end opening of the cylindrical reinforced concrete wall foundation well body 1 is located on the ground and is closed by a manhole cover 6. In this embodiment, the manhole cover 6 is made of cast iron material, and the packaging method with the cylindrical reinforced concrete wall foundation well body 1 adopts the existing technology; the manhole cover 6 is kept in a closed state at ordinary times, and is opened by the maintenance personnel during inspection and maintenance. The manhole cover 6 and the cylindrical reinforced concrete wall foundation well body 1 can be further locked and closed. One end of the main input water pipe 2 and one end of the main output water pipe 3 are respectively inserted into the inside of the cylindrical reinforced concrete wall foundation well body 1, and the other end of the main input water pipe 2 and the other end of the main output water pipe 3 are respectively connected to the underground water supply network located outside the cylindrical reinforced concrete wall foundation well body 1.

[0022] In this embodiment, three transition water pipes 5 are connected in sequence between one end of the main input water pipe 2 and one end of the main output water pipe 3. One end of the main input water pipe 2 is connected to an adjacent transition water pipe 5 through a four-way joint 4, and one end of the main output water pipe 3 is connected to an adjacent transition water pipe 5 through a four-way joint 4. Each two adjacent transition water pipes 5 are connected through a four-way joint 4. Each four-way joint 4 is also connected to one end of two user pipelines 7, and the other end of each user pipeline 7 passes through the cylindrical reinforced concrete wall foundation well body 1 and is connected to the corresponding user pipeline network. A user gate valve 8 and a user water meter 9 are installed in sequence on each user pipeline 7, and all user gate valves 8 and user water meters 9 are located inside the cylindrical reinforced concrete wall foundation well body 1. That is, in this embodiment, there are four four-way joints 4, eight user water meters 9, and eight user gate valves 8 inside the cylindrical reinforced concrete wall foundation well body 1, and each four-way joint 4 is a commercially available product, and the user water meter 9 and user gate valve 8 are also commercially available products. By locating each user's water meter 9 and user's gate valve 8 in a cylindrical reinforced concrete wall foundation well body 1 which is normally closed and located in the well pit, centralized and unified maintenance is facilitated, effectively preventing the water meters exposed to the outside from being damaged, thereby reducing abnormal water supply losses, facilitating the management of inspection and maintenance personnel, and effectively ensuring the service life of the water supply project.

[0023] Specifically, in this embodiment, the user gate valve 8 on each user pipeline 7 is closer to the four-way connector 4 connected to the user pipeline 7 than the user water meter 9 on the user pipeline 7, which meets the usual setting requirements of the user water meter 9 and the user gate valve 8, and is also convenient for separately controlling the on and off of each user pipeline 7.

[0024] Specifically, in this embodiment, the lower end opening of the cylindrical reinforced concrete wall foundation well body 1 extends toward the outside of the cylindrical reinforced concrete wall foundation well body 1 to form a step surface A, which can stably place the cylindrical reinforced concrete wall foundation well body 1 on the ground or in the corresponding well pit to prevent the cylindrical reinforced concrete wall foundation well body 1 from tipping over.

[0025] Specifically, in this embodiment, a heat-insulating material plate 13 is installed on the lower side of the manhole cover 6 to provide heat insulation for the inside of the cylindrical reinforced concrete wall foundation manhole body 1. In this embodiment, the heat-insulating material plate 13 itself is prior art, for example, it can be made of asbestos material, and the installation method adopts prior art.

[0026] Specifically, in this embodiment, a ladder 12 is embedded on the inner side of the cylindrical reinforced concrete wall foundation well body 1, which is convenient for management personnel to enter the cylindrical reinforced concrete wall foundation well body 1 for maintenance and water meter checking. The arrangement of the ladder 12 in this embodiment adopts existing technology and can be made of cast iron material.

[0027] Specifically, in this embodiment, the lower end opening of the cylindrical reinforced concrete wall foundation well body 1 extends toward the inner side of the cylindrical reinforced concrete wall foundation well body 1 to form a stepped surface B, and a dry brick bottom plate 10 is embedded on the stepped surface B. The dry brick bottom plate 10 is formed by stacking a number of bricks and laying them with cement, and the bricks thereon form a number of water-permeable gaps, which can allow a small amount of water in the cylindrical reinforced concrete wall foundation well body 1 to pass through the dry brick bottom plate 10 and infiltrate into the external soil, thereby avoiding the formation of a relatively humid environment inside the cylindrical reinforced concrete wall foundation well body 1 to a certain extent.

[0028] A pier 11 is placed on the dry brick floor 10. The pier 11 is used to support the whole formed by the main input water pipe 2, the main output water pipe 3 and the transition water pipes 5, so as to prevent the whole formed by the main input water pipe 2, the main output water pipe 3 and the transition water pipes 5 from being too close to the bottom of the cylindrical reinforced concrete wall foundation well 1 and being easily affected by moisture. It can also prevent the water pipe from vibrating greatly, thereby ensuring the sensitivity of the user's water meter 9. In this embodiment, the pier 11 is made of marble. In this embodiment, the whole formed by the main input water pipe 2, the main output water pipe 3 and the transition water pipes 5 is at least 20 cm higher than the bottom of the cylindrical reinforced concrete wall foundation well 1, which fully prevents rainwater or sewage from entering the cylindrical reinforced concrete wall foundation well 1 and affecting the user's water meter 9.
