Description

Technical Field

[0001] The present invention relates to the technical field of in-situ curing test devices, and more specifically, to an in-situ soft soil curing test device and method. Background Art

[0002] The in-situ soft soil curing technology is a technology that uses a curing agent to treat soft soil in-situ, aiming to improve the strength and stability of soft soil to meet the needs of engineering construction. This technology evenly mixes the curing agent with the soft soil and utilizes the physical and chemical interactions between the curing agent and the soft soil to form a cured soil mass with sufficient strength. The test is usually carried out in-situ to avoid data deviation caused by transportation.

[0003] According to the search, the patent with the patent number and publication number CN119246250A discloses an in-situ soft soil curing test device. On the support platform of the in-situ soft soil curing test device, a drill rod assembly and a pressing assembly are provided. The drill rod assembly is used for drilling, and the pressing assembly is used to press the soil sampler into the pilot hole drilled by the drill rod assembly. The support platform of the in-situ soft soil curing test device is arranged on the first lifting platform. In this way, the drill rod assembly on the support platform can drill a pilot hole in the soft soil. Then, through the movement of the support platform on the second support platform, the pressing assembly can be aligned with the pilot hole and insert the soil sampler into the pilot hole. Then, the drilling assembly is inserted into the soil sampler and the curing agent is sprayed in, so that the curing test is carried out in-situ. The cured soil mass will not be disturbed during the process of soil sampling and transportation, greatly improving the authenticity of the test data and providing more reliable test data for subsequent engineering construction.

[0004] In view of the above related technologies, the current curing test devices are usually in the above state. Although the above devices can achieve convenient in-situ tests and are easy to use, in the case of a large number of test sites, after each use of the soil sampler, the original soil is likely to remain inside. During subsequent soil sampling operations, the original soil will affect the subsequent soil, thereby affecting the soil test data. Moreover, due to the overall shape of the soil sampler being a hollow tubular structure, it is not convenient to clean its interior, resulting in difficulty in effectively cleaning its interior and affecting the accuracy of subsequent test data. Therefore, an in-situ soft soil curing test device and method are proposed. Summary of the Invention

At the same time, the three-way pipe 263 supplies water to the external ring pipe 247 through the second spring pipe 249, and the subsequent water is sprayed onto the outer surface of the sampling cylinder 150 through the second nozzle 248, so that the rotating brush strip 245 cooperates with the second nozzle 248 to clean the outside of the sampling cylinder 150.

[0052] S4. Withdrawal step: Pull the second connecting rod 500 outward to allow the ratchet bar 391 to withdraw from the ratchet groove 393, so that the movable bar 330 can be reset. Rotate the driving roller 310 in the reverse direction to drive the grounding nail 320 to withdraw from the ground.

[0053] The implementation principle of the embodiment of the present invention is as follows: When in use, by rotating the driving roller 310, the driving roller 310 will drive another driving roller 310 through a transmission belt. The rotation of the driving roller 310 will drive the grounding nail 320 to drive the limiting rod 350 to descend. The grounding nail 320 descends into the ground. Then, the movable bar 330 is lifted upward. The movable bar 330 drives two swing nails 370 to swing outward through the rack 380. At this time, the ratchet bar 391 moves inside the ratchet groove 393 to lock the movable bar 330, so that the stability module 300 fixes the device. Then, by opening the first cylinder 140, the first cylinder 140 will drive the sampling cylinder 150 to descend. The sampling cylinder 150 will enter the ground to take soil. After the soil sampling is completed, the first cylinder 140 drives the sampling cylinder 150 to lift. After the sampling cylinder 150 is lifted, the staff opens the second cylinder 211. The second cylinder 211 drives the push plate 212 to descend. The push plate 212 will descend to push out the soil inside the sampling cylinder 150. After the soil is pushed out, the staff collects it and conducts a curing test through the curing test box 160. Subsequently, the staff turns on the motor 243. The motor 243 will drive the driving gear 244 to drive the gear ring 242 to rotate. The motor 243 will drive a plurality of magnetic bars 250 to rotate. The plurality of magnetic bars 250 will drive a plurality of magnetic blocks 230 to rotate. The plurality of magnetic blocks 230 drive the mounting seat 221 and the fixing rod 215 to rotate. The fixing rod 215 will drive two second rotating rings 214 to rotate between two first rotating rings 213. At this time, the L-shaped pipe 222 rotates at one end of the first spring pipe 225, and the mounting brush 226 contacts and rotates inside the sampling cylinder 150. The water pump 262 is turned on. The water pump 262 supplies water to the first spring pipe 225 through the three-way pipe 263, so that the water source enters the annular pipe 223 through the L-shaped pipe 222, so that a plurality of first nozzles 224 rotate to spray water. Then, the second cylinder 211 is turned on to drive the first nozzle 224 and the mounting brush 226 to perform a reciprocating lifting operation, so that the first nozzle 224 cooperates with the mounting brush 226 to rotate to clean the inside of the sampling cylinder 150, improving the cleanliness inside the sampling cylinder 150. At the same time, the three-way pipe 263 supplies water to the external annular pipe 247 through the second spring pipe 249. Subsequently, the water is sprayed onto the outer surface of the sampling cylinder 150 through the second nozzle 248, so that the rotating brush strip 245 cooperates with the second nozzle 248 to clean the outside of the sampling cylinder 150. After the sampling test is completed, pulling the second connecting rod 500 outward can make the ratchet bar 391 withdraw from the ratchet groove 393, so that the movable bar 330 can be reset. Rotating the driving roller 310 in the reverse direction can drive the grounding nail 320 to withdraw from the ground, facilitating subsequent tests.

[0054] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
