Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering survey and sampling, in particular to a geotechnical engineering survey and sampling device for a highway. Background Art

[0002] Geotechnical engineering is a branch of civil engineering. It is a science that uses engineering geology, soil mechanics, and rock mechanics to solve engineering and technical problems related to rocks and soils in various projects. According to the stages of engineering construction, the work content can be divided into: geotechnical engineering investigation, geotechnical engineering design, geotechnical engineering governance, geotechnical engineering monitoring, and geotechnical engineering testing. With the prosperity and development of the economy, various highway construction projects have sprung up like mushrooms after rain. In various highway construction projects, geotechnical engineering occupies a very important position, among which investigation and sampling are particularly important;

[0003] Traditional highway geotechnical engineering survey sampling devices have some shortcomings. The sampling method is generally manual marking and drilling. During the sampling process, workers first mark the designated position, then move the drilling device to the designated position, and align the rock drill with the marked position. Due to the height difference between the rock drill and the marked position, it is difficult for workers to align the rock drill with the marked position, so the manual drilling position is not accurate enough, and the drilled samples are of different sizes, which makes it difficult to carry out subsequent survey processes.

[0022] In this embodiment, the front and rear ends of the sliding frame 64 are fixedly connected with a limiting frame 615, the inner sides of the two groups of limiting frames 615 are slidably connected with sliding rods 616, the front and rear ends of the sliding frame 64 are fixedly connected with a control handle 617 near the outer side of the limiting frame 615, the upper ends of the two groups of fixing rods 62 are fixedly connected with a support plate 618, the lower ends of the two groups of main springs 63 are fixedly connected to the outer side of the fixing seat 61 near the outer side of the fixing rod 62, the upper ends of the two groups of main springs 63 are fixedly connected to the lower end of the sliding frame 64, the lower end of the connecting ring 69 is fixedly connected to the upper end of the filter bucket 610, and the shape of the filter bucket 610 is a truncated cone, the lower ends of the two groups of auxiliary springs 613 are fixedly connected to the upper end of the sliding frame 64, the upper ends of the two groups of auxiliary springs 613 are fixedly connected to the lower end of the baffle 614 near the outer side of the limiting rod 612, and the lower ends of the two groups of sliding rods 616 are fixedly connected to the upper end of the bottom plate 1 on one side of the fixing seat 61.

[0023] Specifically, the control handle 617 is pulled downward, so that the control handle 617 drives the sliding frame 64 to move downward, and the limiting frame 615 slides downward along the sliding rod 616. At the same time, the sliding frame 64 slides downward along the fixing rod 62, so that the sliding frame 64 compresses the main spring 63 downward. At this time, the filter bucket 610 first touches the ground, and then the through-line is checked to see whether it is located at the center of the filter bucket 610. Then the position of the sampling mechanism 6 is adjusted to align the center of the filter bucket 610 with the line, and then the control handle 617 is pulled downward to move the sliding frame 64 downward again. Since the filter bucket 610 touches the ground, the filter bucket 610 no longer moves with the sliding frame 64, so that the sliding frame 64 moves along the limiting rod 612 slides downward, so that the sliding frame 64 stretches the secondary spring 613 downward, so that the rock drill 68 contacts the marked line, and then the motor 65 is started, so that the motor 65 drives the spiral rod 67 to rotate through the rotating shaft 66, so that the spiral rod 67 drives the rock drill 68 to rotate, and then the rock drill 68 drills a hole at the marked line.

[0025] Specifically, a worker first draws a line at a designated position, and then pulls the push handle 3 to make the universal wheel 4 roll on the ground, so that the sampling mechanism 6 can be moved to the designated position.

[0026] Working principle:

[0027] When in use, the worker first draws a line at the designated position, and then pulls the push handle 3 to make the universal wheel 4 roll on the ground, so that the sampling mechanism 6 can be moved to the designated position, and then the control handle 617 is pulled downward to make the control handle 617 drive the sliding frame 64 to move downward, and the limiting frame 615 slides downward along the sliding rod 616, and at the same time, the sliding frame 64 slides downward along the fixed rod 62, so that the sliding frame 64 compresses the main spring 63 downward, and then the filter bucket 610 first touches the ground, and then the piercing line is checked to see if it is located at the center of the filter bucket 610. If it is not located at the center, the push handle 3 is pulled to make the universal wheel 4 move again. The sampling mechanism 6 is rolled on the ground to adjust the position of the sampling mechanism 6, so that the center of the filter bucket 610 is aligned with the marked line, and then the control handle 617 is pulled downward to make the sliding frame 64 move downward again. Since the filter bucket 610 contacts the ground, the filter bucket 610 no longer moves with the sliding frame 64, so that the sliding frame 64 slides downward along the limit rod 612, so that the sliding frame 64 stretches the auxiliary spring 613 downward, so that the rock drill 68 contacts the marked line, and then the motor 65 is started, so that the motor 65 drives the screw rod 67 to rotate through the rotating shaft 66, so that the screw rod 67 drives the rock drill 68 to rotate, and then the rock drill 68 is rotated. 8 Drilling is performed at the marked position, and the control handle 617 is then pulled downward to move the slide frame 64 downward, so that the rock drill 68 is drilled into the ground, and the spiral rod 67 contacts the ground, and the spiral rod 67 carries the sample in the ground upward, and the sample falls to the inner wall of the filter bucket 610, and the filter bucket 610 filters the finer sample, so that the worker can take out the finer sample that falls from the outside of the filter bucket 610, and by moving the slide frame 64 downward, the slide frame 64 moves downward along the fixed rod 62, so that the slide frame 64 compresses the main spring 63 downward, and the slide frame 64 filters The bucket 610 moves to contact the ground, so that it is easy to observe whether the marked area is located at the center of the filter bucket 610, and then it is easy to align the rock drill 68 with the marked area, so as to accurately drill and sample the marked area. Secondly, the rock drill 68 drills into the ground, so that the spiral rod 67 contacts the ground, and the spiral rod 67 carries the sample in the ground upward, and the sample falls to the inner wall of the filter bucket 610, which can make it easier for the filter bucket 610 to filter out finer samples, so that workers can take out the finer samples that fall from the outside of the filter bucket 610, which is helpful for subsequent survey processes.
