Description

Technical Field

[0001] The invention relates to the technical field of water pressure testing, in particular to an engineering geological survey water pressure testing device. Background Art

[0002] The water pressure test is a permeability test conducted in a borehole. It uses a plug to isolate a certain length of the borehole, then presses water into the borehole at a certain pressure, and measures the pressure flow rate under the corresponding pressure. The pressure flow rate per unit test section length under a certain force is used to characterize the permeability of the rock in the borehole section. It is a common method for evaluating the permeability of rock mass. In engineering geological surveys, it is necessary not only to test the soil and vegetation of the area, but also the water in the area.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present invention provides an engineering geological survey water pressure test device, which has the following beneficial effects:

[0017] 1. The engineering geological survey water pressure test device integrates the spiral blades and the water delivery pipe on the cart, which is convenient for overall transportation. At the same time, the adjustment range of the equipment is increased by setting the adjustment mechanism to improve practicality;

[0018] 2.

Conversely, the stopper acts as a limit to the slider to prevent it from disengaging from the slide rail.

[0021] 5. When the engineering geological survey water pressure test device is using the adjustment mechanism, after the mounting plate slides to the highest point, the plate body is pressed against the slide rail, so that when the frame is pushed, the plate body directly pushes the block 1, and the limit on the slide block is cancelled, which is convenient for disassembly. If the adjustment mechanism is not lifted to the highest point, when the frame is pushed, when the plate body contacts the block 1, the plate body rises due to the presence of the spring 2, and the height of the block 1 remains unchanged, so that the block can still limit the slide block, thereby improving practicality.

[0038] At present, the engineering geological survey water pressure test devices on the market are all carried out outdoors. After drilling holes in the ground, water is injected while measuring relevant data based on flow meters and water pressure gauges to achieve water pressure tests.

[0039] In the related art, the separate components of the water pressure test device are integrated and installed on a mobile mechanism, so as to facilitate the transfer of the geological survey water pressure test device. However, in actual use, its adjustment range is small and its function is relatively simple. In addition, in the water pressure laboratory, the overall stability of the equipment cannot be guaranteed, which makes it inconvenient to use and brings inconvenience to the water pressure test work.

[0040] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides an engineering geological survey water pressure test device. When it is needed, the cart 10 only needs to move the equipment to the specified position, and the height of the spiral blade 24 and the water supply pipe 22 is adjusted in turn by the adjustment mechanism 20, and then the water supply mechanism 11 is cooperated to realize the water injection operation, and then the relevant data is measured by the flow meter and pressure gauge, which is more convenient and quick, and improves the convenience of the device.

[0041] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0042] Combination Figure 1-Figure 4 The embodiment of the present application provides an engineering geological survey water pressure test device, including: a cart 10, a water supply mechanism 11 is arranged on the top of the cart 10, a slide rail 12 is fixedly connected to the top of the cart 10, a slider 13 is slidably connected to the slide rail 12, a frame 14 is fixedly connected to the top of the slider 13, at least two of the slide rails 12, the slider 13 and the frame 14 are provided, and an adjustment mechanism 20 is arranged on both of the two frames 14, a mounting plate 21 is slidably connected to the inner side of the frame 14, and the adjustment mechanism 20 is used to adjust the height of the mounting plate 21, a water supply pipe 22 is arranged on one of the mounting plates 21, and a motor 23 is fixedly connected to the other mounting plate 21, and the output end of the motor 23 is fixedly connected to The spiral blade 24, the water supply pipe 22 is connected to the water supply mechanism 11 through a water pipe, a moving wheel 30 is arranged at the bottom of the cart 10, an electric push rod 40 is fixedly connected inside the cart 10, a push plate 41 is slidably connected inside the cart 10, the output end of the electric push rod 40 is tightly attached to the push plate 41, a positioning rod 42 is fixedly connected to the bottom of the push plate 41, a slide groove 50 is opened on the slide rail 12, a rod body 51 is slidably connected in the slide groove 50, one end of the rod body 51 is inserted into the cart 10, a spring 52 is sleeved on the outside of the rod body 51, two ends of the spring 52 are respectively fixedly connected to the cart 10 and the rod body 51, and a ball 53 is fixedly connected to the top of the rod body 51.

[0043] If a water pressure test is required, the cart 10 is directly pushed to move the cart 10 through the moving wheels 30 at the bottom until the cart 10 is moved to the specified position, and then a frame 14 is manually pushed to drive the mounting plate 21, the motor 23 and the spiral blade 24 thereon to move. Then, the height of the mounting plate 21 and the structure on the mounting plate 21 are adjusted through the adjustment mechanism 20, and the motor 23 is turned on at the same time to rotate the spiral blade 24. Then, the spiral blade 24 is made to penetrate the ground to achieve the punching operation, and finally, the adjustment mechanism 20 is used to adjust the height of the mounting plate 21 and the structure on the mounting plate 21. The height of the mounting plate 21 and the structure thereon is adjusted again until it is reset, the frame 14 is manually pulled to reset the frame 14, and then another frame 14 is pulled to make the frame 14 drive another mounting plate 21 and the water supply pipe 22 to move, and finally the water supply mechanism 11 is docked with the water supply pipe 22, and the adjustment mechanism 20 is opened to adjust the height of the water supply pipe 22 so that it penetrates into the opened hole, and then the water supply mechanism 11 is opened to make the water supply mechanism 11 deliver water to the hole, and relevant data are measured by the flow meter and the water pressure gauge to realize the water pressure test;

[0044] When the frame 14 is pushed, the frame 14 slides on the slide rail 12 through the slider 13 until the slider 13 contacts the ball 53, pushes the ball 53 and the rod 51 into the slide groove 50, and squeezes the spring 52, and at the same time, the rod 51 pushes the push plate 41 and the positioning rod 42 to slide out from the bottom of the cart 10, and then the positioning rod 42 contacts the ground to support the entire cart 10, so that the moving wheel 30 is separated from the ground, the stability is improved, and the position of the equipment is prevented from shifting during the subsequent water injection process, affecting normal use. When the electric push rod 40 is actively turned on, the output end of the electric push rod 40 pushes the push plate 41 and the positioning rod 42, so as to realize the active adjustment of the height of the positioning rod 42 and improve practicality.

[0045] Specifically, during the test, a water stop plug is installed in the borehole to isolate the test section from the surrounding rock mass. Then, a certain head pressure is applied by a water pump to press water into the test section. The water will penetrate into the surrounding rock mass through the cracks in the borehole wall. Within a certain period of time (usually about 10 minutes), the amount of water pressed in and the amount of pressure applied are recorded. By measuring the change in water volume during this period, the unit water absorption (ω) of the rock mass can be calculated. The formula is: ω=Q / (s·L), where Q is the amount of seepage water, s is the pressure head height, and L is the length of the test section.

The water pipe is installed at the water outlet of the water pump and fixed on the water tank. The pressure gauge and the flow meter are installed on the water pipe to monitor the pressure and flow in the water pipe.

[0047] In some embodiments, a groove is provided on the slider 13, and the ball 53 is embedded in the groove. After the position of the frame 14 is adjusted to align the groove on the slider 13 with the ball 53, the ball 53 is embedded in the groove through the rebound force of the spring 52, thereby limiting the slider 13 and the frame 14.

[0048] In some embodiments, the adjustment mechanism 20 is composed of a servo motor and a threaded rod, the servo motor is fixed on the top of the frame 14, the threaded rod is rotatably connected in the frame 14, and the mounting plate 21 is threadedly connected to the threaded rod.

[0054] The cam 72 is then moved back into position after the locking cam 73 is unlocked, and the locking cam 73 is unlocked when the locking cam 73 is unlocked, thereby locking the cam 72 in the unlocked position.

[0055] In some embodiments, the distance from the bottom of the second stopper 72 to the top of the slide rail 12 is equal to the height of the plate 70, so that after the second stopper 72 slides out, the plate 70 can be tightly attached to the top of the slide rail 12, thereby facilitating subsequent disassembly.
