Method used

The present embodiment is simple in structure, and the sampling shell that conical structure is provided with can make the take-up after shell resampling and sampling completes easier, adopts peripheral guiding and fixed column support, can not stay metal rod in the middle of soil sample, It can increase the stability of sampling, and it is also equipped with a protective cover, which can protect the soil samples in time after the sampling is completed; it is equipped with an anti-backflow inner eaves to reduce the drop of soil samples. When sampling, first remove the protective cover, then use the pressing plate to fix the guide and fixed column in the soil, rotate the fixed block to fix the thrust cover and the push block, and rotate the ring handle, at this time, the threaded push rod will push the sampling shell to the inside of the soil The soil sample enters the cylindrical sampling cavity from the first bell mouth structure and the second bell mouth structure. The material guide effect is good, making it easier for the soil to enter the cylindrical sampling cavity. After the sampling is completed, pull it out through the pressing plate Cover the sampling case with the protective cover and seal it in time. After the sampling is completed, the sampling case can be separated from the thrust cover, and after the thrust cover is taken away, the sampling case can be installed on the guide column. Push out the soil sample in the cylindrical sampling chamber.
The present embodiment provides a kind of backfill soil sampling device for engineering supervision, including the sampling housing 1 that the outside is conical structure setting, and the inside of the sampling housing 1 is a cylindrical sampling cavity 2, and the sampling housing 1 A number of guiding and fixing columns 3 are evenly distributed on the wall of the device, and the upper part of the guiding and fixing columns 3 is provided with a pressing plate 4. The upper part of the sampling housing 1 is threaded with a thrust cover 5, and the thrust cover 5 is movably connected with a push block. 6. A threaded push rod 7 is formed on the push block 6, and the threaded push rod 7 is threadedly connected with the pressing plate 4.

Example Embodiment

[0022] Examples:
[0023] Such as Figure 1-5 As shown,
[0024] This embodiment provides a backfill soil sampling device for engineering supervision, which includes a sampling housing 1 with a conical structure on the outside. The inside of the sampling housing 1 is a cylindrical sampling cavity 2, and the sampling housing 1 has a wall A number of guiding and fixing posts 3 are evenly arranged. The upper part of the guiding and fixing posts 3 is provided with a pressing plate 4, the upper part of the sampling housing 1 is threadedly connected with a thrust cover 5, and the thrust cover 5 is movably connected with a pushing block 6, so A threaded push rod 7 is formed on the push block 6, the threaded push rod 7 is threadedly connected with the pressing plate 4, the end of the threaded push rod 7 is provided with an annular handle 8, and the end of the sampling housing 1 is provided with The material guide opening 101 corresponding to the cylindrical sampling cavity 2 is provided with an anti-backflow inner eave 102 corresponding to the material guide opening 101 on the inside of the sampling housing 1, and a protective cover 9 is provided at the front end of the material guide opening 101. The material guide port 101 is a bell mouth structure with a small inner side and a large outer side. The bottom of the eaves of the anti-backflow inner 102 is formed with a bell mouth structure 2 corresponding to the bell mouth structure of the material guide port. When the sampling shell is pressed down, the soil sample enters the cylindrical sampling cavity from the bell mouth structure 1 and bell mouth structure 2, which can achieve a good flow diversion effect. There are 4 guide fixing posts 3, and a through hole 103 corresponding to the guide fixing post is provided on the wall of the sampling housing 1 and on the thrust cover 5. The inner diameter of the through hole 1 is slightly larger than that of the guide The outer diameter of the fixed column and the guide fixed column can play a very good supporting role. The upper part of the sampling housing 1 is provided with a straight pipe section 104, and the straight pipe section is provided with an external thread corresponding to the thrust cover, which facilitates better connection with the thrust cover. A number of rotatable fixed blocks 501 corresponding to the push blocks are evenly arranged on the thrust cover 5. The fixed blocks are staggered from the guiding fixed posts. The size of the push blocks corresponds to the inner diameter of the cylindrical sampling chamber. The fixed blocks can be used To fix the push block so that the thrust cover and the push block are connected together to push the sampling housing downward for sampling. At the same time, after sampling is completed, the sampling housing and the thrust cover can be separated first, and after the thrust cover is removed, push Blocks can also be used to push out soil samples in cylindrical sampling chambers. The inner side of the protective cover 9 is provided with a tapered internal thread corresponding to the sampling shell 1, which is beneficial to timely sealing and protection after soil sampling is completed.
[0025] The structure of this embodiment is simple, and the sampling shell set in a tapered structure can make the shell re-sampling and taking out after sampling is completed more easily. The outer peripheral guide fixed pillar is used for support, and no metal rod is left in the soil sample, which can increase sampling. It is also equipped with a protective cover to protect the soil sample in time after the sampling is completed; the anti-backflow inner eaves can reduce the fall of the soil sample. When sampling, first remove the protective cover, and then use the pressing plate to fix the guide and fixed column in the soil, rotate the fixed block to fix the thrust cover and the push block, rotate the ring handle, at this time the threaded push rod will push the sampling shell into the soil Sampling is carried out by movement. The soil sample enters the cylindrical sampling cavity from the bell mouth structure 1 and bell mouth structure 2, and the guiding effect is good, which makes it easier for the soil to enter the cylindrical sampling cavity. After the sampling is completed, pull it out by pressing the plate The sampling shell is sealed with a protective cover in time. After sampling is completed, the sampling shell can be separated from the thrust cover. After the thrust cover is removed, the sampling shell can be mounted on the guide fixed column. The push block can be used Push out the soil sample in the cylindrical sampling chamber.
