[0002] In the construction and maintenance of roads in China, it is often necessary to drill and sample the road surface to understand its condition. Current methods involve directly using sampling equipment with a hollow drill bit to drill into the road surface and obtain a columnar sample. During drilling, water needs to be continuously added to prevent the drill bit from overheating. During sampling, cooling water from the drill bit flows onto the ground, and this cooling water mixed with concrete debris can contaminate the road surface. Therefore, after the operation, manual cleaning or high-pressure water cleaning is required, which is time-consuming and labor-intensive. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a road surface sampling and protection device that can form a temporary sewage cavity between the drill bit and the road surface. After drilling is completed, the sewage can be directly discharged into a collection tray through the outlet pipe for centralized treatment without the need for additional cleaning procedures, thus ensuring a clean environment during the sampling process.

[0004] To address the aforementioned technical problems, this utility model provides a road surface sampling and protection device, comprising a sponge pad, a waterproof barrier, a collection tray, and a limiting base. The sponge pad is laid on the road surface to be sampled; the waterproof barrier is placed on the sponge pad, and a water outlet pipe is provided on the lower side of the waterproof barrier. The water outlet pipe is equipped with a switch valve and communicates with the inner space of the waterproof barrier; the collection tray is located below the water outlet of the water outlet pipe; limiting rods are also provided on both sides of the waterproof barrier, and the limiting base is located on the outer side of the waterproof barrier and is equipped with a locking post, which can lock the limiting rods.

[0005] As an improvement to the above solution, the locking post has an opening on its side, and a vertically arranged telescopic block is provided in the opening. The telescopic block is used to lock the limiting rod located in the opening.

[0006] As an improvement to the above solution, the telescopic block is connected to the connecting rod, the connecting rod is connected to the locking post via a spring, and the top of the connecting rod is provided with a handle.

[0007] As an improvement to the above solution, a rubber pad is also provided between the sponge pad and the waterproof fence.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0018] like Figure 1 and Figure 2As shown, the first embodiment of this utility model provides a road sampling protection device, including a sponge pad 1, a waterproof barrier 2, a collection tray 3, and a limiting base 4. The sponge pad 1 is laid on the road surface to be sampled; the waterproof barrier 2 is disposed on the sponge pad 1, and a water outlet pipe 5 is provided on the lower side of the waterproof barrier 2. A switch valve 6 is provided on the water outlet pipe 5, and the water outlet pipe 5 communicates with the inner space of the waterproof barrier 2; the collection tray 3 is disposed below the water outlet of the water outlet pipe 5; limiting rods 21 are also provided on both sides of the waterproof barrier 2, and the limiting base 4 is disposed on the outer side of the waterproof barrier 2 and is provided with a locking post 7, which can lock the limiting rods 21.

[0019] Using the aforementioned protective equipment, a temporary sewage cavity can be formed between the drill bit 100 and the road surface, improving cooling efficiency. After drilling is completed, the sewage can be directly discharged into the collection tray 3 through the outlet pipe 5 for centralized treatment, eliminating the need for additional cleaning procedures, thus improving sampling efficiency and ensuring a clean environment during the sampling process. After the sewage is discharged from the outlet pipe 5, the waterproof enclosure 2 can be quickly removed from the locking post 7, making disassembly and assembly convenient. After the waterproof enclosure 2 is removed, the sponge pad 1 is no longer under the pressure of the waterproof enclosure 2 and can completely absorb the remaining small amount of cooling water. Simply remove and clean the sponge pad 1 for reuse.

[0020] To reliably secure the waterproof enclosure 2 while ensuring convenient assembly and disassembly, the locking post 7 has an opening 71 on its side. A vertically positioned telescopic block 72 is located within the opening 71, locking the limiting rod 21 positioned within it. The telescopic block 72 is connected to a connecting rod 73, which is connected to the locking post 7 via a spring 74. A handle 75 is located at the top of the connecting rod 73. When the waterproof enclosure 2 needs to be installed, simply pull the telescopic block 72 upwards using the handle 75, inserting the limiting rod 21 into the opening 71 of the locking post 7. Releasing the handle 75 allows the telescopic block 72, driven by the spring 74, to press down the limiting rod 21, preventing displacement or tilting of the waterproof enclosure 2 during drilling.

[0021] Preferably, a rubber pad 8 can also be provided between the sponge pad 1 and the waterproof enclosure 2. The rubber pad 8 can improve the sealing between the waterproof enclosure 2 and the sponge pad 1, and can also serve as a buffer between the metal waterproof enclosure 2 and the sponge pad 1, preventing the sponge pad 1 from being crushed during use.

[0022] Preferably, the waterproof enclosure 2 is in the shape of a cylindrical tube. The limiting base 4 is fixedly connected to the base of the sampling equipment. It should be noted that connecting the limiting base 4 to the base of the sampling equipment can improve the stability of the limiting base 4.

[0023] Combination Figure 3As shown, according to the second embodiment of this utility model, the difference from the first embodiment is that the waterproof enclosure 2 is further provided with a water inlet pipe 9. The water inlet pipe 9 has a first connecting port 91 facing upwards, which is connected to the water tank 10. The water inlet pipe 9 also has a second connecting port 92, which is located on the side of the waterproof enclosure 2 and communicates with the internal space of the waterproof enclosure 2. The water inlet pipe 9 is a metal pipe with a certain supporting capacity, and the water tank 10 is directly connected to the water inlet pipe 9. Before operation, water can be filled into the water tank 10, and then the water tank 10 is screwed to the water inlet pipe 9. The water in the water tank 10 flows into the waterproof enclosure 2 through the water inlet pipe 9 to provide cooling water for the drill bit. When the water level in the waterproof enclosure 2 reaches the second connecting port 92, due to atmospheric pressure, the water in the water tank 10 no longer flows out, thus achieving automatic control of the cooling water level. During the rotation of the drill bit, the cooling water is consumed. When the second connection port 92 is exposed, the water in the water tank 10 will flow back into the waterproof enclosure 2. The drilling process does not require manual water addition, which can ensure the safety of nearby personnel.

[0024] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
