Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of double-layer underground wells, in particular to a double-layer underground well which can be fixed after the backfill layer is lost. Background Art
[0002] Due to the scouring effect of groundwater or plate displacement on some airport aprons, the water-stabilizing layer, lime soil layer or other backfill layer under the apron pavement is lost, forming a cavity next to the inner barrel and the refueling branch pipe, which in turn affects the stability of the inner barrel of the double-barrel refueling well and its internal refueling equipment. A support structure is added between the inner and outer barrels, which is mainly composed of springs, screws and U-shaped buckles to reduce the occurrence of safety accidents. At present, some aviation ground wells are set as double-layer structures;
[0003] However, as the ground surface changes, the backfill layer originally used to fix the inner barrel and the branch pipe will slowly disappear, resulting in a cavity around the inner barrel and the refueling branch pipe. It is inconvenient to fill the cavity formed around the inner barrel and the refueling branch pipe and fix the refueling branch pipe and the inner barrel, resulting in poor stability of the inner barrel. At the same time, it is impossible to clean the inner wall of the inner barrel, resulting in water and soil sticking to the inner wall of the inner barrel, causing pollution to the inner wall of the inner barrel and affecting the use of the inner barrel. Based on this, a double-layer ground well that can be fixed after the backfill layer is lost is proposed. Utility Model Content

A spring 34 is arranged outside the screw rod 33, and one end of the spring 34 is fixedly installed on the outer surface of the inner barrel 2. The spring 34 is used to ensure that the support structure 3 has sufficient supporting force, maintain the stability of the inner barrel 2 and its internal equipment, and reduce the occurrence of safety accidents. The other end of the spring 34 is fixedly installed on the inner wall of the outer barrel 1, and a grouting hole 5 is opened on the inner barrel 2.
[0028] Embodiment 2
[0029] Based on Example 1, please refer to Figure 1-Figure 6 As shown, since some aviation wells are currently set as double-layer structures, the backfill layer originally used to fix the inner barrel and the branch pipe will slowly disappear as the ground surface changes, resulting in a cavity formed around the inner barrel and the refueling branch pipe. At this time, the U-shaped buckle 31 can be disassembled by the set screw 32 and the screw rod 33, thereby facilitating the disassembly of some components of the inner barrel 2, so as to achieve the purpose of disassembling some components of the inner barrel 2, and facilitate the subsequent filling of the cavity around the inner barrel 2 and the refueling branch pipe, so as to further fix the refueling branch pipe and the inner barrel 2;
[0030] Embodiment 3
[0031] Based on Example 2, please refer to Figure 1-Figure 6 As shown, a cleaning structure 4 is provided on the outer barrel 1, and the cleaning structure 4 includes a slide seat 43, which is moved along a slide rail ring 42 as a path, and the slide seat 43 drives a fixed rod 48 to move while the slide seat 43 moves. The slide seat 43 is slidably mounted on the inner barrel 2, and a cleaning brush plate 49 is fixedly mounted on the slide seat 43. The inner wall of the inner barrel 2 is cleaned by the cleaning brush plate 49 to prevent water and soil from sticking to the inner wall of the inner barrel 2 and polluting the inner wall of the inner barrel 2. One side of the cleaning brush plate 49 fits with the inner wall of the inner barrel 2, and a slide rail ring 42 is fixedly mounted on the inner barrel 2. The slide seat 43 is moved along a slide rail ring 42 as a path, and the slide seat 43 is slidably mounted on the slide rail ring 42, and a fixed plate 44 is fixedly mounted on the slide seat 43, and a fixed rod 48 is fixedly mounted on the fixed plate 44. The cleaning brush plate 49 is fixedly mounted on the fixed rod 48, and the fixed rod 48 moves while the cleaning brush plate 49 is driven to clean the inner wall of the inner barrel 2;
[0032] A rotating rod 45 is rotatably mounted on the fixed plate 44, and a turning knob 47 is fixedly mounted on the rotating rod 45. The rotating turning knob 47 drives the gear 46 to rotate along with the rotating rod 45 through the rotating rod 45. A toothed ring 41 is fixedly mounted on the outer barrel 1, and a gear 46 is fixedly mounted on the rotating rod 45. The gear 46 and the toothed ring 41 are meshed with each other. The wheel 46 rotates while moving along the inner ring of the toothed ring 41, and at the same time moves through the slide seat 43 with the slide rail ring 42 as the path.
[0033] Working principle of the utility model: In order to ensure the stability of the inner barrel 2 and the equipment inside it, a support structure 3 is added between the outer barrel 1 and the inner barrel 2. The support structure 3 is mainly composed of a U-shaped buckle 31, a set screw 32, a screw 33 and a spring 34. When in use, the U-shaped buckle 31 is inserted into the upper edge of the inner barrel 2, and then fixed to the inner barrel 2 by the set screw 32. The screw 33 provides a guiding effect for the spring 34 to prevent the spring 34 from shifting during compression and rebound movement, causing the entire support structure 3 to fail. The spring 34 is used to ensure that the support structure 3 has sufficient supporting force, which can maintain the stability of the inner barrel 2 and the equipment inside it, and reduce the occurrence of safety accidents;
[0034] As the ground surface changes, the backfill layer originally used to fix the inner barrel and the branch pipe will slowly disappear, resulting in a cavity formed around the inner barrel and the refueling branch pipe. At this time, the U-shaped buckle 31 can be disassembled by the set screw 32 and the screw rod 33, thereby facilitating the disassembly of some parts of the inner barrel 2, so as to achieve the purpose of disassembling some parts of the inner barrel 2, and facilitate the subsequent filling of the cavity around the inner barrel 2 and the refueling branch pipe, so as to further fix the refueling branch pipe and the inner barrel 2;
[0035] The rotating knob 47 drives the gear 46 to rotate along with the rotating rod 45 through the rotating rod 45. The gear 46 rotates and moves along the inner ring of the toothed ring 41. At the same time, it moves through the slide seat 43 with the slide rail ring 42 as the path. The slide seat 43 moves and drives the fixed rod 48 to move. The fixed rod 48 moves and drives the cleaning brush plate 49 to clean the inner wall of the inner barrel 2 to prevent water and soil from sticking to the inner wall of the inner barrel 2, causing pollution to the inner wall of the inner barrel 2, and affecting the use of the inner barrel 2, thereby further ensuring the cleanliness of the inner barrel 2 and improving the use effect of the inner barrel 2.
