[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0021] It should be noted that if the embodiment involves directional indications (such as up, down, bottom, top, etc.), the directional indications are only used to explain the relative position relationship, motion condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications will also change accordingly. The terms "first", "second" are only for description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first", "second" can be explicitly or implicitly included one or more features. Unless otherwise specified and limited, the terms "set", "connected", "connected" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0022] As shown in Figure 1-Figure 2 A kind of overflow structure for urban construction, including shaft 1, overflow operator 2 and connecting pipe fitting, shaft 1 and overflow operator 2 can be buried underground, one end of overflow operator 2 protrudes from ground, and the outer periphery of the section of overflow operator 2 protruding from ground is provided with ring cage 3, ring cage 3 can be filled with gravel, and ring cage 3 is a mesh structure, the technical solution is to set a mesh structure around overflow operator 2, and fill gravel into ring cage 3, the water flow can be initially filtered by gravel when passing through, and at the same time, it can also avoid that gravel is picked up by children or residents in the later use process, damaging the integrity of the facility.

[0023] As described above, shaft 1, overflow operator 2 and connecting pipe fitting are all prior art, which can form a basic overflow structure, the connecting pipe fitting can connect shaft 1 and overflow operator 2, and can connect shaft 1, overflow operator 2 and municipal inspection well.

[0024] Further, in the technical solution, in order to facilitate the transportation and installation of ring cage 3, ring cage 3 adopts a split structure, i.e. ring cage 3 includes bottom cage 301 that can be placed on the ground and top cage 302 that is hingedly connected to the top opening of bottom cage 301, and top cage 302 is provided with a plurality of metal bent strips 3021 that can be clamped on bottom cage 301. Through manual operation, metal bent strips 3021 can be bent from bottom to top and wound on bottom cage 301 to fix top cage 302 on bottom cage 301. In the technical solution, as shown in Figure 2As shown, the top cage 302 is hinged with the bottom cage 301 through the chain link 303, which is a closed loop structure formed by bending a metal rod, like the chain link in the prior art, which is simple in structure and can make the top cage 302 open and close smoothly, facilitating the operator to fill the gravel in the gravel filling area surrounded between the bottom cage 301 and the overflow operator 2 during construction.

[0025] Further, as shown in the drawings, Figure 2 As shown, the bottom opening of the bottom cage 301 can be sleeved on the outer periphery of the overflow operator 2, and the bottom of the bottom cage 301 can receive the gravel. After the operator fills the gravel in the gravel filling area surrounded between the bottom cage 301 and the overflow operator 2, the gravel can not only be surrounded around the overflow operator 2, but also can press the bottom cage 301 to prevent it from being moved.

[0026] In the technical solution, to ensure the filtering effect of the gravel, the difference between the outer diameter of the bottom cage 301 and the outer diameter of the overflow operator 2 is 300mm-500mm, and the operator needs to fill the gravel in the area between the bottom cage 301 and the overflow operator 2.

[0027] At the same time, to increase the service life of the annular cover cage 3, a protective coating can be coated on the surface of the bottom cage 301 and the top cage 302. The protective coating is a prior art and can play a role in preventing rust. At the same time, the protective coating can also provide a protective color for the annular cover cage 3, so that it is easier to blend into the environment.

[0028] In the embodiment, to reduce the manufacturing cost, the top cage 302 and the bottom cage 301 are both formed by interlacing or welding a plurality of metal strips, and the diameter of the metal strip is 3mm-5mm, so as to increase the overall structural strength of the annular cover cage 3.

[0029] Working principle: by setting the annular cover cage 3 around the overflow operator 2 and filling the gravel inside the annular cover cage 3, the water flowing to the overflow operator 2 can be initially filtered by the gravel, ensuring the effect of laying gravel. At the same time, it can also avoid that the gravel is picked up by children or residents in the later use process, damaging the integrity of the facility.

[0030] Based on the ideal embodiment of the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the contents in the specification, and the technical scope must be determined according to the scope of claims.
