[0013] Figure 2 It is a schematic diagram of the structure of another embodiment of the present invention;

[0014] Figure 3 yes Figure 2 A schematic enlarged view of the local structure in FIG.

[0015] In the figure: a water collecting cylinder 1, a sealing ring 2, a pedal rod 3, a drain pipe 4, an arc-shaped jack 5, a magnetic suction plate 6, a sealing software 7, an arc-shaped clamping block 8, a clamping groove 9, and a core drilling cylinder 10. DETAILED DESCRIPTION

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0017] like Figure 1 As shown, a core sampling drainage device includes a water collecting tube 1, which is in the shape of a hollow cylinder. The diameter is 200-300mm, the wall thickness is about 3mm, and the outside is coated with anti-corrosion material. A sealing ring 2 is arranged at the bottom of the water collecting tube 1. The sealing ring 2 is made of flexible rubber or high-density sponge, annular, and is fixed to the water collecting tube 1 by glue. It has a certain thickness and can fully contact with the measured surface when under pressure to ensure its sealing. A drainage pipe 4 is fixed to the lower side end of the water collecting tube 1, and a plugging device for closing the annular gap between the water collecting tube 1 and the upper part of the core drilling tube 10 is arranged on the upper part of the water collecting tube 1.

[0018] Embodiment 1: Figure 1 As shown, the plugging device includes a plurality of arc-shaped sockets 5 opened at the upper side end of the water collecting barrel 1, and a magnetic plate 6 is arranged on the outer side of the arc-shaped socket 5. The magnetic fixation between the magnetic plate 6 and the outer edge of the arc-shaped socket 5 can realize the quick disassembly and assembly of the plugging device. A sealing software 7 is fixed on the inner side of the magnetic plate 6, which passes through the arc-shaped socket 5 and extends to the inner side of the water collecting barrel 1. The sealing software 7 adopts a plurality of rubber brush wires or metal brush wires, which are thin and have good flexibility. The outer wall of the core drilling barrel 10 of the internal drilling core is sealed by the sealing software 7 on the inner side of the magnetic plate 6, so as to prevent the slurry splashed out of the internal core drilling barrel 10 from spraying out from the top opening, thereby ensuring the sealing of the top of the water collecting barrel 1.

[0019] Embodiment 2: Figure 2 , 3As shown, the plugging device includes a plurality of arc-shaped blocks 8 uniformly clamped on the top of the water collecting tube 1, a plurality of clamping grooves 9 capable of clamping with the top of the water collecting tube 1 are formed at the lower part of the arc-shaped blocks 8, a sealing software 7 is fixed to the inner side of the arc-shaped blocks 8, and the plurality of spaced-apart clamping grooves 9 at the top thereof can be used to adjust the fixed position of the arc-shaped blocks 8, thereby realizing the position adjustment of the sealing software 7 on the inner side thereof. When encountering a core drilling tube 10 with a larger diameter, the arc-shaped blocks 8 can be adjusted outward so that the sealing software 7 on the inner side thereof can effectively block the annular gap, and when encountering a core drilling tube 10 with a small diameter, the reverse adjustment can be made. In this way, the plugging device can adjust the position of the core drilling tubes 10 with different diameters to ensure that the annular gap at the top is sealed.

[0020] like Figure 2 As shown, pedal rods 3 are fixed on both sides of the water collecting tube 1. The pedal rods 3 are made of high-strength, lightweight alloy material and are in a rectangular shape. They are used for manual stepping or evenly balancing the water collecting body.

[0021] The drain pipe 4 is tilted downward, made of high-strength, lightweight alloy material, a hollow cylinder, and has a wall thickness of about 2 mm. The drain pipe 4 is tilted to discharge water and mud in the water collecting tube 1.

[0022] The water collecting cylinder 1 is filled with a sponge block, which is sleeve-shaped and fits closely to the inner wall of the water collecting cylinder 1 . The sponge block can not only absorb the slurry inside the water collecting cylinder 1 , but also effectively prevent the mud in the slurry from splashing out.

[0023] The implementation principle of a core sampling and drainage device in the embodiment of the present application is:

[0024] Place the device on the roadbed to be tested and make the sealing ring 2 at the bottom contact the ground. The staff steps on the foot pedal to pressurize the sealing ring 2 to ensure waterproof sealing, seal the water and mud in the water collecting tube 1, and use the core drilling tube 10 to fall along the inside of the water collecting tube 1 to perform core drilling sampling to avoid contact with the sponge block. The mud generated during the core drilling sampling process will gather in the water collecting tube 1. When the mud level in the water collecting tube 1 rises, the sponge block plays a filtering and adsorption role. The liquid in the mud is discharged along the drain pipe 4, and the impurities in the mud are filtered by the sponge block. The sealing device on the upper part of the water collecting tube 1 can prevent the mud splashing out during core drilling sampling from splashing out along the annular gap at the top of the water collecting tube 1, thereby ensuring the environmental protection of the core drilling sampling by the personnel and avoiding mud from polluting the environment.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
