Description

Technical Field

[0001] The utility model relates to the technical field of gas station operating wells, in particular to a waterproof structure of an underground oil tank operating well in a gas station. Background Art

[0002] An underground tank pit at a gas station is a well located inside or around a gas station specifically for operating, maintaining, and inspecting the valves on the tanks. This pit is typically designed to provide easy access for workers to perform refueling, draining, cleaning, testing, and other maintenance operations.

[0003] Waterproofing the various wells at oil depots and gas stations has always been a major challenge for gas stations. Oil depots and gas stations often have a wide variety of well types, each with a different purpose. Once the depots and stations are built and operational, water seepage and accumulation in these wells are common, impacting their normal operation and posing serious safety risks, even leading to significant economic losses. Because underground oil tanks at gas stations can be either full or empty, in areas with generally high groundwater levels, the buoyancy of the groundwater and the landfill material above the tanks can cause the tanks to shift. This can lead to deformation of process and electrical piping within the operating wells, cracking of the well walls, and ultimately leaks.

[0004] In the prior art, patent application number CN211735514U discloses a waterproof device for a gas station operating well, comprising a base, a well cover, and a sealing rubber ring. The well cover is installed on the upper part of the base, and a sealing rubber ring is installed between the well cover and the base. The base comprises a base body, a center hole is provided at the center of the base body, and a slope is formed on the upper end surface of the base body. The slope is arranged along the circumferential direction of the base body, and a step groove is provided between the slope and the center hole. The high end of the slope is adjacent to the upper end of the step groove, and the low end of the slope extends outward; the lower end of the step groove is adjacent to the center hole. The advantages of this utility model are: it can effectively solve the problem of easy water ingress and accumulation in the well cover of the existing operating well, reduce the daily maintenance cost of the aisle-type operating well; effectively isolate the operating well from the outside space, avoid rainwater intrusion, and achieve a multi-layer waterproof effect.

[0005] With respect to the above scheme, there are the following technical problems: in the daily use of the gas station operating well, if it rains, the inside of the operating well may leak, affecting the underground oil tank inside the operating well. At this time, a gas station underground oil tank operating well waterproof structure is needed. When the gas station underground oil tank operating well waterproof structure in the prior art is in use, its well cover is too heavy, and if it needs to be opened, it is too troublesome and not convenient to use. At the same time, the setting of the waterproof structure is too simple and not convenient for daily waterproofing. Therefore, the gas station underground oil tank operating well waterproof structure in the prior art has the defect that the well cover is too troublesome to open. Utility Model Content

Example 2

[0028] See also Figure 3 The utility model provides a technical solution: a waterproof structure for an underground oil tank operation well of a gas station. In this embodiment, six grouting holes 19 are provided on the ground outside the operation well body. The six grouting holes 19 are arranged in a circular array with the central axis of the operation well body as the center. A polyurethane waterproof layer 20 formed by grouting through the grouting holes 19 is provided outside the operation well body. The thickness of the polyurethane waterproof layer 20 at the protective casing is less than the length of the protective casing.

[0029] Specific construction plan: Use a drill bit to drill 60cm deep grouting holes 19 around the operating well body. The drill holes are about 30cm away from the operating well wall. Drill 6 holes evenly around the well. Use a 1.8 MPa grouting machine to inject polyurethane plugging agent around the operating well wall to form a water-proof layer.

[0030] Technical principle: Polyurethane slurry is injected into the foundation soil through a grouting pipe. The slurry removes moisture and air from soil particles or cracks by filling, penetrating, compacting and splitting, and then takes up its place. After a certain period of time, the slurry cements and solidifies the originally loose soil particles into a whole, thereby achieving the purpose of waterproofing and leak-proofing. The material performance characteristic is that the oily polyurethane grouting material reacts immediately with water. Since water participates in the reaction, the slurry will not be diluted and washed away by water. This is an advantage that other grouting materials do not have. Under the action of pressure, the slurry is poured into the gaps or holes in the concrete, process pipelines, and electrical pipelines, and at the same time penetrates around the gaps, eventually forming a mesh structure, becoming a low-density, water-containing elastomer with good adaptability and good water-stopping properties.
