[0001] The invention relates to the field of water pressure test devices, in particular to a water pressure test device for geological survey in horizontal directional drilling engineering. Background Art

[0002] The water pressure test is an important part of engineering geological survey, and its purpose is to obtain hydrogeological data of rock formations. It mainly uses a water pump or the deadweight of a water column to press clean water into the test section of the borehole, and calculates the relative permeability of the rock mass and understands the degree of fracture development based on the relationship between the amount of water pressed in a certain period of time and the amount of pressure applied.

[0003] When using the existing geological survey water pressure test device, water is usually extracted by a water pump and then sent into the borehole by a water pipe. However, in actual use, there are still some defects: after the water pipe is inserted into the borehole, there is a lack of fixing measures between the water pipe and the inside of the borehole, which makes the water pipe easily detached from the inside of the borehole, resulting in the inability of the water source to enter the borehole. At this time, the surrounding staff need to manually insert the water pipe into the borehole again, which is extremely inconvenient and easily affects the test data, resulting in inaccurate test results.

[0025] Working principle: When using the present application, first check through the transparent window 8 whether there is sufficient water in the water tank 5. If the water is insufficient, the piston 9 can be removed, and then the water is replenished along the water inlet toward the inside of the water tank 5, and then the piston 9 is inserted into the water inlet. If the water is sufficient, the handrail 4 is directly held, and the multiple groups of pulleys 2 are cooperated to push the entire device to a suitable position, and then the entire device is reversed so that the multiple groups of anti-slip seats 3 on the left side of the base 1 are attached to the ground, and the multiple pulleys 2 are located on the right side, so as to fix the entire device, and the setting of the anti-slip seat 3 can ensure the stability of the entire device, and then the catheter 13 and other components are removed from the inside of the cylinder 25, and the catheter 13 is inserted into the inside of the test borehole.
