Description

Technical Field

[0001] This utility model relates to the field of explosives testing technology, specifically to an air-water combined immersion device for explosives. Background Technology

[0002] In rock plug blasting operations, after the explosives are loaded and connected in each borehole of the rock plug body, blasting cannot be carried out immediately. This is because the equipment and facilities on site need to be dismantled and transported outside the tunnel after loading; the temporary sealing section downstream of the gate well needs to be completed; the tunnel between the slag pit and the temporary sealing section needs to be filled with water; and the explosives in the boreholes need to be immersed in water with a certain water pressure for a period of time until the conditions for blasting are met. The stability of the performance of the explosives after underwater immersion is directly related to the success or failure of the entire project. Therefore, the explosives need to be tested before use (simulating the immersion of the explosives to be used in blasting operations at the same water depth).

[0003] The immersion of explosives is typically conducted in natural water bodies that meet the required water pressure. The explosives to be tested are placed in steel cages and lowered into the water (at the same depth as the actual blasting location), with floats attached and secured to the shore. After the required immersion time, the steel cages containing the explosives are retrieved, the explosives are counted, and removed for further testing. This method is constrained by the natural environment. If there is no natural water body at the construction site that meets the required immersion depth, the explosives must be transported across regions, significantly increasing coordination difficulties and safety risks. The open environment surrounding natural water bodies also increases the difficulty and safety risks of monitoring the explosives. Furthermore, immersing explosives in natural water bodies poses a risk of material leakage and water pollution.

[0004] In recent years, some projects have adopted the method of laying water pipes along the slope within the construction site, with a device for soaking explosives connected to the bottom of the pipes. Water is added to the pipes to artificially create water pressure, thus soaking the explosives. While this method effectively replaces the process of soaking explosives in natural water, it is difficult to implement if there is no suitable location on site to lay the water pipes along the slope or if it is difficult to add water to the top of the pipes. Therefore, this invention provides a combined air-water soaking device for explosives. Utility Model Content

Detailed Implementation

[0031] Please refer to the attached document. Figure 1 This application illustrates an air-water combined immersion device for explosive materials, used to simulate immersion tests of explosive materials used in blasting operations at the same water depth. Specifically, it includes: an immersion body, a pressure gauge 2, an exhaust pipe 3, a water filling pipe, an air filling pipe 5, a first valve 4, and a second valve 6.

[0032] The soaking body has a soaking chamber for accommodating explosive material a. A pressure gauge 2 is installed on the side of the soaking body. The pressure gauge 2 is used to detect the air pressure inside the soaking chamber. An exhaust pipe 3 and a water and air filling pipe 5 are fixedly connected to the top side of the soaking body. A first valve 4 is installed on the exhaust pipe 3, and a second valve 6 is installed on the water and air filling pipe 5.

[0033] During use, the soaking body is placed on a level surface. The explosive device a is placed in the soaking chamber of the soaking body. Then, both the first valve 4 and the second valve 6 are opened. A certain amount of water is injected into the soaking chamber through the water / air filling pipe 5. Gas in the soaking chamber is discharged through the exhaust pipe 3. Once the water level is higher than the height of the explosive device a, the first valve 4 is closed. Then, high-pressure gas is injected into the soaking chamber through the water / air filling pipe 5. The gas pressure in the soaking chamber is observed through the pressure gauge 2. The high-pressure gas acts on the liquid surface in the soaking chamber, increasing the liquid pressure to simulate liquid pressure. After closing the second valve 6 and maintaining this position for a predetermined time, the first valve 4 is opened, and gas is released through the exhaust pipe 3. The explosive device a is then removed for further testing, completing the experimental operation.

[0034] This application uses gas to pressurize the liquid in the soaking chamber, which requires less water. Moreover, releasing the gas and depressurizing after the experiment is safer, which significantly improves construction efficiency and greatly reduces construction costs.

[0035] In one embodiment, the immersion body includes: a steel pipe 1, a first sealing steel plate 9, and a second sealing steel plate 12.

[0036] The steel pipe 1 is set horizontally and can be placed on flat ground (where site conditions are less demanding).

The second sealing steel plate 12 is fixedly installed at the second end of the steel pipe 1. The second sealing steel plate 12 is preferably installed by flange. Its detachable installation method makes it easy to remove the second sealing steel plate 12. After the explosive material a is filled into the soaking chamber of the soaking body, the second sealing steel plate 12 is fixedly installed again.

[0037] In one embodiment, the steel pipe 1 is a pressure-resistant steel pipe, and a corrosion-resistant steel pipe with a thickness of 10mm or more is selected.

[0038] In one embodiment, a flange 10 is fixedly connected to the second end of the steel pipe 1. The flange 10 is fully welded to the outside of the second end of the steel pipe 1. The second sealing steel plate 12 and the flange 10 are fixedly installed by bolt assembly 13. The flange connection structure is easy to disassemble and install. A flange gasket 11 is provided between the second sealing steel plate 12 and the flange 10. The flange gasket 11 is used to increase the sealing between the second sealing steel plate 12 and the flange 10.

[0039] In one embodiment, a water level observation pipe 7 is provided, one end of which is fixedly connected to a first sealing steel plate 9, and a third valve 8 is fixedly installed on the water level observation pipe 7.

[0040] When water is injected into the soaking chamber of the soaking body, the third valve 8 is opened, and the water level observation pipe 7 is connected to the soaking chamber of the soaking body. Based on the water level at the water level observation pipe 7, the water level inside the soaking chamber of the soaking body can be determined.

[0041] In one embodiment, the water level observation tube 7 includes: a transparent vertical section 702 and a connecting pipe 701. The connecting pipe 701 is connected between the bottom end of the transparent vertical section 702 and the first sealing steel plate 9. The side of the transparent vertical section 702 is provided with scale marking lines.

[0042] The transparent vertical section 702 is made of rigid PVC transparent pipe, and the connecting pipe 701 can be made of flexible hose; the user can easily observe the water level in the transparent vertical section 702 and judge the water level line b inside the soaking chamber of the soaking body based on the scale markings.
