[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-5 , the present invention provides a technical solution:

[0023] A new type of underground water meter box that is easy to maintain, including an underground box body 1 buried in the soil, wherein the underground box body 1 is made of a 5mm thick hot-rolled steel plate. The outer wall surface of the underground box body 1 is coated with waterproof glue, and three layers of fiberglass are arranged outside the waterproof glue. The waterproof glue can also play the role of gluing the hot-rolled steel plate and the fiberglass. The inner wall of the underground box body 1 is painted with anti-rust paint. Since the interior of the underground box body 1 is relatively humid, the welding part of the hot-rolled steel plate is prevented from directly contacting moisture.

[0024] The top inner wall of the buried box 1 is provided with an insulation layer 9, and the insulation layer 9 is made of polyurethane sheet material to reduce the heat loss inside the buried box 1. Since the ground temperature is lower than that of the underground in winter, only the top inner side of the buried box 1 needs to be provided.

[0025] The top of the underground box 1 is provided with a protruding maintenance access channel 2, and an upper cover 4 is provided on the maintenance access channel 2. The height of the maintenance access channel 2 is made based on the height of the frozen soil layer in each region. The upper cover 4 is exposed to the outside, and the upper cover 4 can be opened to enter the inner cavity of the underground box 1 through the maintenance access channel 2. A waterproof rubber strip is provided between the maintenance access channel 2 and the upper cover 4, and the waterproof rubber strip improves the sealing effect between the access channel 2 and the upper cover 4 to prevent water and cold wind from entering.

[0026] A bearing boss 5 is provided at the connection between the maintenance access channel 2 and the underground box 1, and a heat preservation pad 6 is placed on the top of the bearing boss 5. The bearing boss 5 is used to place the heat preservation pad 6, and the heat preservation pad 6 is used to isolate the maintenance access channel 2 from the inner side of the underground box 1. The frozen soil layer is in direct contact with the bearing boss 5, resulting in a low temperature inside the bearing boss 5. The heat preservation pad 6 is used to isolate the maintenance access channel 2 from the inner cavity of the underground box 1, reducing the cold air inside the bearing boss 5 from entering the inner cavity of the underground box 1. Through holes connected to the inside are opened at the four corners of the surface of the bearing boss 5, and the through holes are used to install the remote water meter antenna.

[0027] The bottom of the side wall of the underground box 1 is preset with a first water pipe joint 7 and a second water pipe joint 3 which are seamlessly connected, wherein the first water pipe joint 7 is arranged on the side wall at the rear side of the underground box 1, and the second water pipe joint 3 is arranged on the side walls on both sides of the underground box 1. When manufacturing the underground box 1, the first water pipe joint 7 and the second water pipe joint 3 are directly welded to the underground box 1, and the connection between the first water pipe joint 7 and the second water pipe joint 3 and the underground box 1 is made into a seamless weld, thereby avoiding the problem of water seepage in the connection between the existing underground water meter box and the water distribution pipe.

[0028] The outer side of the first water pipe joint 7 is connected to the main water pipe, and the inner side of the first water pipe joint 7 is connected to the first water branch pipe. Second water branch pipes corresponding to the second water pipe joints 3 are evenly distributed on the left and right sides of the first water branch pipe, and each of the second water pipe joints 3 is provided with a water meter 8.

[0029] The inner wall of the buried box 1 is provided with a pedal 10 below the maintenance access passage 2. The pedal 10 is often provided on the top of the first water pipe joint 7 to prevent the maintenance personnel from always stepping on the first water pipe joint 7.

[0030] A lifting lug is provided on the top of the underground box 1, and the lifting lug is used when the underground box 1 is transported.
