Description

Technical Field

[0001] This utility model relates to the field of oil tank technology, specifically to a soil-covered storage tank. Background Technology

[0002] Earthen storage tanks, also known as earthen-covered oil tanks, refer to oil tanks placed in a tank chamber covered by soil, with the soil covering the top and surrounding area of ​​the tank chamber being no less than 0.5 meters thick. There are two main ways to classify oil tanks: one is according to their building characteristics, which can be divided into above-ground oil tanks, underground oil tanks, semi-underground oil tanks, and cave oil tanks; the other is according to the building materials, which can be divided into metal oil tanks and non-metal oil tanks.

[0003] During the use of soil-covered storage tanks, the top of the tank is covered with a layer of soil for a long time. On the one hand, the soil layer is prone to water and soil erosion during heavy rain, resulting in subsidence and scour gullies, which damages the soil layer and causes it to lose its protective function. On the other hand, the tank body of the soil-covered storage tank is continuously subjected to pressure. Common internal support structures of soil-covered storage tanks have the problem of uneven support. Most support structures can only support the top and bottom of the tank, while the side support of the soil-covered storage tank is ineffective and lacks strength.

[0004] There is an urgent need for a soil-covered storage tank to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a soil-covered storage tank to solve the problems mentioned in the background art, such as the soil cover layer being prone to soil erosion, insufficient inner support strength of the soil-covered storage tank, and uneven support.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a soil-covered storage tank, comprising a tank body, a supporting sand bed laid at the bottom of the tank body, the supporting sand bed being laid on the ground, a soil-covered layer surrounding the tank body, on which water and soil conservation grass is planted, and an inspection walkway is provided, with a drainage ditch provided on one side of the inspection walkway, the drainage ditch encircling the soil-covered layer and collecting water into the drainage system by utilizing the difference in elevation, further preventing rainwater from causing the soil-covered layer to sink or forming erosion ditches. A maintenance passage is laid on the right side of the bottom of the supporting sand bed. The maintenance passage is located at the lower right of the main body of the storage tank. Manholes are installed on both sides of the top of the main body of the storage tank. A gas chamber is installed at the top of the main body of the storage tank. The manholes and gas chambers are connected to the interior of the main body of the storage tank. The outlets of the manholes and gas chambers penetrate the cover layer and are located above the cover layer. Three sets of support rings are installed inside the main body of the storage tank. The outside of the support rings is tightly connected to the inside of the main body of the storage tank. Reinforcing internal supports are fixedly connected inside the support rings. Support rods are fixedly connected between the support rings. A connection port is fixedly connected on the right side of the bottom of the main body of the storage tank. A connecting pipe is installed at the bottom of the connection port and is located at the bottom of the main body of the storage tank. An alarm module is installed inside the maintenance passage. The alarm module is equipped with a temperature monitoring module and a gas concentration detection module.

[0007] Preferably, the interior of the storage tank body is provided with openings for instruments such as level gauges, thermometers, and pressure gauges.

[0008] Preferably, there are eight sets of support rods, which are arranged in a ring on the right side of the support ring and fit closely to the interior of the tank body.

[0009] Preferably, the temperature monitoring module and the gas concentration detection module are connected to the alarm module via wires, and the temperature monitoring module and the gas concentration detection module are located below the connection port.

[0010] Preferably, settlement monitoring rods are provided on both sides of the top of the main body of the storage tank, a ladder is installed at the bottom of the manhole, and a sealed door is installed at the entrance of the maintenance passage.

[0011] Preferably, the exterior of the tank body is coated with a corrosion-resistant layer, and a fireproof and heat-insulating soil layer is provided between the soil covering layer and the tank body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the soil-covered storage tank not only realizes the functions of soil and water conservation, daily inspection, enhanced support strength and support uniformity, as well as detection and alarm, but also realizes the functions of protection and corrosion resistance.

[0013] (1) By planting Yulong grass with water and soil conservation function on the soil cover layer, water and soil conservation of the soil cover layer can be achieved. Inspection walkways and drainage ditches are set up to collect the difference in elevation into the drainage system, which further prevents rainwater from causing the soil cover layer to sink or forming scour ditches.

[0014] (2) By setting up a tank body, a support ring, a support rod and a reinforced inner brace, the support ring inside the tank body can support the inside of the tank. The support ring is evenly distributed on both sides and the middle of the inside of the tank body. The support rod on the support ring can evenly support the inner wall of the cylindrical tank body. The support rod fits against the inner wall of the tank body. The reinforced inner brace inside the support ring can improve the strength of the support. This structure realizes the functions of facilitating the enhancement of support strength and uniform support.

[0015] (3) By setting up a settlement monitoring rod, maintenance channel, alarm module, temperature monitoring module and gas concentration detection module, the settlement monitoring rod makes it convenient for maintenance personnel to observe whether the main body of the storage tank has sunk and the height of the sinking. The temperature monitoring module inside the maintenance channel can monitor the temperature inside the channel in real time. Once the temperature is too high or too low, the alarm module can remotely alarm to remind maintenance personnel to maintain it. Once the gas concentration detection module detects that the gas concentration inside the maintenance channel exceeds the standard, the alarm module will also remotely alarm to remind maintenance. The maintenance channel makes it convenient for maintenance personnel to check whether there is water accumulation at the bottom of the oil tank. This structure realizes the functions of easy detection and alarm, and improves the safety of the main body of the storage tank.

[0016] (4) By setting up a soil cover layer, a fireproof and heat-insulating soil layer and a corrosion-resistant layer, the main body of the storage tank is buried under the soil cover layer. The soil cover layer can protect the main body of the storage tank. The corrosion-resistant layer on the outside of the main body of the storage tank can prevent the moisture in the soil layer from reacting with the surface of the tank and causing rust and corrosion. The fireproof and heat-insulating soil layer can better insulate and prevent fire. This structure realizes the functions of easy fire prevention and corrosion resistance. Attached Figure Description
