Description

Technical Field

[0001] This utility model relates to the field of core sampling and testing technology for pine piles used for riverbank protection, and in particular to a core sampling device. Background Technology

[0002] Although pine piles are said to be "pines that can withstand water for ten thousand years," they are only suitable for use below the groundwater level. For pine piles located in areas with fluctuating water levels, the junctions are prone to rotting. Therefore, pine pile revetments will rot after a period of use. In addition, the grazing by herbivorous fish underwater will accelerate the rotting process, usually requiring repeated repairs every few years. Rotting is the most significant problem when using pine pile revetments.

[0003] When river levels fluctuate frequently, the pine piles, being constantly at the boundary of these fluctuations, are subject to external erosion factors such as ultraviolet radiation and pests, resulting in noticeable severe rot. In such cases, soil erosion and pile breakage can easily occur, leading to bank collapse and personal injury. When the water level of the dam river drops, the original pine pile revetment is positioned significantly above the water level, leaving the piles completely exposed to the water surface year-round. Consequently, they are subjected to long-term erosion from wind, rain, biological erosion, and oxidation, causing severe rot above the soil and posing a serious safety hazard.

[0004] The damage to the pine stakes poses a significant safety hazard. Therefore, it is necessary to implement appropriate bank protection measures and long-term effective monitoring methods in a timely manner to ensure the safety of people's lives and property.

[0005] To address this, a core sampling device is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a core sampling device that drills core samples from inside the pile body for indoor chemical testing and mechanical performance testing to understand the material, structure, and mechanical properties of the pile body, thereby evaluating the material and performance of the pile body.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 This utility model provides a core sampling device, including: a core drilling assembly 100 for core sampling of pine piles, a gripping assembly 200 for easy hand support, a connecting assembly 300 for movably connecting the core drilling assembly 100 and the gripping assembly 200, and a locking assembly 400 for positioning. The gripping assembly 200 is disposed at the top of the core drilling assembly 100 via the connecting assembly 300, and the locking assembly 400 is disposed on the connecting assembly 300. The core drilling assembly 100 includes a support rod 110, and a spiral drill rod 120 is integrally formed at the bottom of the support rod 110. The gripping assembly 200 includes a sleeve 210 disposed at the top of the support rod 110, and a handle 220 is fixedly connected through the inner cavity of the sleeve 210. The connecting assembly 300 is located between the sleeve 210 and the support rod 110.

[0027] The bottom end of the auger drill rod 120 has an inverted conical structure so that the auger drill rod 120 can drill into the interior of the pine pile.

[0028] The grip bar 220 has rubber sleeves 221 fixedly fitted at both ends of its surface. The rubber sleeves 221 can improve the comfort of holding the grip bar 220 and also prevent the hand from slipping.

[0029] The connecting assembly 300 includes a support 310 fixedly connected to the bottom of the sleeve 210. The bottom of the support 310 is fixedly connected to two symmetrical support plates 320. The top of the support rod 110 is placed between the two support plates 320 and is movably connected to the support plates 320.

[0030] The upper part of the support rod 110 has two symmetrical protrusions 330 fixedly connected. The protrusions 330 and the support plate 320 are arranged in a one-to-one correspondence. One end of the protrusion 330 is rotatably connected to the corresponding support plate 320 through a rotating shaft. The connecting component 300 enables the rotatable connection between the sleeve 210 and the support rod 110. When the holding component 200 and the core drilling component 100 are arranged perpendicular to each other, core sampling of pine piles can be performed. When the holding component 200 and the core drilling component 100 are arranged parallel to each other, the core sampling device can be folded and stored for easy carrying.

[0031] The locking component 400 includes a positioning block 410 that contacts the top of the support rod 110. A telescopic component is provided between the positioning block 410 and the support 310. The positioning block 410 can position the holding component 200, so that the holding component 200 can be stably kept in a horizontal position with the core drilling component 100, avoiding accidental rotation during the core drilling of the pine pile, thus ensuring the stability of the core drilling of the pine pile. At the same time, it can also be used as a knob to rotate the stud 420.

[0032] The telescopic component includes a stud 420 fixedly connected to the top of the positioning block 410. A threaded sleeve 430 is threaded onto the surface of the stud 420. The top of the threaded sleeve 430 is fixedly connected to the bottom of the support 310. The telescopic component enables the positioning block 410 to be adjusted up and down, so as to position and unlock the holding component 200 according to actual usage requirements.

[0033] Among them, the center lines of the support rod 110, the auger drill rod 120, the support 310, the positioning block 410, the stud 420, and the threaded sleeve 430 are all on the same straight line.

[0034] The working principle of this utility model is as follows: Holding the rubber sleeve 221, align the bottom end of the spiral drill rod 120 with the pile body, apply force to the grip rod 220 and rotate it. The grip rod 220 drives the sleeve 210, connecting assembly 300, locking assembly 400 and core drilling assembly 100 to rotate, drilling a core sample into the pile body through the spiral drill rod 120. The core sample is kept in its original state, and then subsequent chemical composition analysis and mechanical property testing are performed to understand the material, structure and mechanical properties of the pile body. This allows for the evaluation of the material and performance of the pile body, timely detection and problem solving, and prevention of internal corrosion of the pile core, which could lead to fracture of the pile body from the inside out. Hazard source; By rotating the positioning block 410, the positioning block 410 drives the stud 420 to rotate in the inner cavity of the threaded sleeve 430. Under the action of the thread, the stud 420 moves upward in the inner cavity of the threaded sleeve 430. The stud 420 drives the positioning block 410 to move synchronously until it reaches the maximum limit, at which point the holding component 200 can be unlocked. At this time, the holding component 200 can be rotated, so that the holding component 200 drives the support 310, the support plate 320 and the locking component 400 to rotate synchronously around the pivot axis until the holding component 200 and the core drilling component 100 are parallel. The core drilling sampling device can then be folded and stored to reduce the space occupied by the core drilling sampling device and make it easy to carry.

[0035] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
