Description

Technical Field

[0001] The utility model relates to the technical field of water pressure test equipment, in particular to a water pressure test device for engineering geological exploration. Background Technique

[0002] The water pressure test is an in-situ test that uses high pressure to inject water into a borehole and calculates the water absorption of the rock mass to understand the development of rock mass fractures and permeability. The water pressure test uses special water-stop equipment to isolate a certain length of the borehole test section, and then injects water into this section of the borehole with a fixed water head. The water penetrates into the rock mass through the fractures around the borehole wall, and finally the penetrated water volume will tend to a stable value. According to the water pressure head, the test section length, and the stable infiltration water volume, the permeability of the rock mass can be determined. It can be known from the retrieval report of the novelty search agency that the publication number: CN211740995U discloses a water pressure test device for engineering geological exploration, including a water tank. A first groove is opened above the inner side of the water tank, and the lower surface of the first groove is designed in an arc state. An extension member is inserted into the water tank. A second groove is opened at the bottom end of the side surface of the extension member. A first spring is fixed on the inner wall of the second groove, and the other end of the first spring is fixed in a first baffle. A first sealing ring is fixed below the first baffle; for the water pressure test device for engineering geological exploration, the pressing plate fixed at the lower end of the threaded rod moves downward, avoiding affecting the test results when the storage battery is out of power, facilitating the outflow of water while avoiding the entry of mud, preventing blockage, and being beneficial to the smooth progress of the test. The use of the extension member can not only increase the water storage capacity in the water tank but also facilitate carrying, reducing the trouble brought during carrying;

[0003] The above-mentioned water pressure test device for engineering geological exploration disclosed in the patent can increase the water storage capacity of the water tank through the provided extension member, so as to achieve the purpose of timely water injection. However, there are still some deficiencies in its use process: 1. By increasing the water storage capacity of the water tank, the water supply can be increased, but the increased water storage capacity of the water tank is still certain. During the test, when more water is needed, personnel still need to interrupt the test to add water. It is not possible to directly perform the water addition operation during the test when the water volume is insufficient, and the test continuity is not ideal, which is likely to affect the test results. Therefore, we propose a water pressure test device for engineering geological exploration. Content of the Utility Model

The storage battery 16 is used to supply power to the controller 10, both waterproof touch switches 9 and the solenoid valve 11. Through the setting of a series of structures, the utility model can continuously supply water to the water supply area during the test, effectively avoid the situation of interrupting the test to add water due to insufficient water volume, improve the continuity of the test, and can automatically add water when the water volume in the water storage area is insufficient, without affecting the continuous supply of water into the water supply area, and improve the use stability.

[0026] Working principle: When in use, water is pre-added to both the water supply area and the water storage area. The water level in the water storage area is flush with the bottom of the floating block 8, and the water level in the water supply area is flush with the bottom of the piston 4. When conducting a water pressure test operation, insert the housing 101 into the borehole, open the valve 104, and press down the T-shaped extrusion rod 5. While the T-shaped extrusion rod 5 moves downward, it compresses the spring 6. The T-shaped extrusion rod 5 drives the piston 4 to move downward to squeeze the water inside the water supply area. Under the squeezing force, the water inside the water supply area sequentially enters the housing 101 through the first one-way valve 1, the valve 104, the meter, and the connecting pipe 103. The water inside the housing 101 is discharged through multiple water outlet holes 102 to conduct the water pressure test operation. At the same time, the meter measures the amount of water flowing through. The specific principle of the water pressure test has been mentioned in the patent with the publication number CN211740995U and will not be elaborated here;

[0027] While the piston 4 moves downward, a suction force is also generated above it. Under the suction force, the water inside the water storage area is sequentially extracted through the second one-way valve 15 and the connecting pipe 7. The extracted water enters the water supply area and is located above the piston 4. When the piston 4 is pressed down to the lowest position, immediately release the squeezing force on the T-shaped extrusion rod 5, so that the elastic force of the compressed spring 6 drives the piston 4 to move upward through the T-shaped extrusion rod 5. While the piston 4 moves upward, the water located above the piston 4 flows into the lower part of the piston 4 through the third one-way valve 14. The water below the piston 4 can continue to flow out through the first one-way valve 1. When the piston 4 moves upward to the initial position, the T-shaped extrusion rod 5 can be pressed down continuously, so that the piston 4 can move up and down cyclically. During the process of the piston 4 moving up and down cyclically to squeeze the water, the water can be continuously sucked, so that the water supply area can be continuously supplied with water, effectively avoiding the situation where the test needs to be interrupted to add water due to insufficient water volume. By continuously supplying water to the water supply area, the continuity of the test is improved, thereby reducing the situation where the test results are affected;

[0028] Connect the solenoid valve 11 to the external pressurized water supply pipeline. The pressurized water supply pipeline can be a tap water supply pipeline, a high-position automatic downward drainage pipeline, etc. As the water in the water storage area is pumped out, the water level in the water storage area gradually decreases. Under the action of gravity, the floating block 8 moves downward with the water level. When the floating block 8 moves downward to contact the lower waterproof touch switch 9, the lower waterproof touch switch 9 is triggered to turn on. The lower waterproof touch switch 9 transmits a signal to the controller 10, and the controller 10 controls the solenoid valve 11 to open, so that the external water enters the water storage area successively through the solenoid valve 11 and the fourth one-way valve 12. As the water in the water storage area increases and the water level rises, under the action of buoyancy, the floating block 8 moves upward with the water level. When the top of the floating block 8 contacts the bottom of the upper waterproof touch switch 9, the upper waterproof touch switch 9 is triggered to turn on, indicating that the water has been added to the required amount at this time. At this time, the upper waterproof touch switch 9 transmits a signal to the controller 10, and the controller 10 controls the solenoid valve 11 to close, stopping the continuous water addition operation. By automatically adding water when the water volume in the water storage area is insufficient, it does not affect the continuous supply of water into the water supply area, improving the use stability.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
