Abstract
Claims
1. A temporary storage device for subgrade sampling samples, comprising a sand storage box (1) having an annular cavity inside, characterized in that, The annular cavity inside the sand storage box (1) is used to fill sand and form a sand layer inside the sand storage box (1). The roadbed sample is buried in the sand layer for temporary storage. The sand storage box (1) is equipped with an annular sealing cover (2), and the top of the annular sealing cover (2) is provided with a fan-shaped opening (201) arranged in an annular array. A detachable sealing component (3) is provided above the annular sealing cover (2), and the sealing component (3) is used to close the fan-shaped opening (201) to prevent the sand inside the sand storage box (1) from being lost.
2. A temporary storage device for subgrade sampling samples as claimed in claim 1 wherein, The inner surface of the annular enclosure (2) and the outer surface of the sand storage box (1) are threaded together to realize the installation of the annular enclosure (2) and the sand storage box (1).
3. A temporary storage device for subgrade sampling samples as defined in claim 1, wherein, The sealing component (3) includes an annular baffle (301), with a sealing gasket (302) and a fan-shaped sealing plate (303) arranged in an annular array fixedly connected to the bottom of the annular baffle (301). The fan-shaped sealing plate (303) and the fan-shaped opening (201) are adapted to each other.
4. A temporary storage device for subgrade sampling samples as defined in claim 3, wherein, A fixed sleeve (4) is fixedly connected to the center of the top of the annular closed cover (2). The fixed sleeve (4) has a through opening (5) and a movable groove (6). A pressing plate (7) is provided at the through opening (5). The pressing plate (7) is located above the annular baffle (301). The annular baffle (301) is sleeved on the outer surface of the fixed sleeve (4).
5. A temporary storage device for roadbed sampling samples according to claim 4, characterized in that, An annular recess is provided at the bottom of the inner wall of the through-hole (5), and a limit ring (8) is provided in the annular recess. A limit hole (9) is provided on the pressing plate (7) above the limit ring (8).
6. A temporary storage device for subgrade sampling samples as defined in claim 4, wherein, The movable groove (6) is provided with a fixed plate (10) that can move up and down. A threaded rod (11) is threadedly connected to the fixed sleeve (4). The bottom of the threaded rod (11) is rotatably connected to the fixed plate (10). A control knob (12) is fixedly connected to the top of the threaded rod (11) and above the fixed sleeve (4).
7. A temporary storage device for subgrade sampling samples as defined in claim 6, wherein, The bottom of the fixed plate (10) is fixedly connected to a positioning shaft (13), and the clamping plate (7) is provided with a positioning hole (14) that works with the positioning shaft (13).
