Description

Technical Field

[0001] The utility model relates to the field of field sampling equipment for soil profile investigation and whole-section soil specimens, in particular to a field collection frame and a sampling kit for a whole-section soil column. Background Art

[0002] The collection of entire soil profiles is a highly professional field practical skill. After the entire profile soil column is trimmed into a prototype using profile knives, shovels, pickaxes and other tools, it is nested in a wooden frame of a certain size. Then, a large number of tools such as complex knives and wire saws are used to cut out a complete, crack-free and unbroken overall soil sample with a depth of 1 meter, a width of 22 cm and a thickness of 7 cm. It is placed in the wooden frame, then flattened and sealed to make a whole-section specimen.

[0003] The existing technology of directly cutting, repairing and packing by stamping with a wooden frame has two major defects: (1) Since the soil is not a tightly connected whole structure and the wooden sampling frame cannot be directly embedded in the soil, the entire section of the soil column is repaired after a rough range is drawn. It generally faces problems such as fracture and collapse. This phenomenon is particularly significant in sections with shallow groundwater or high gravel content, which greatly increases the difficulty of collecting soil profiles. Repairing a half-collapsed section also causes great psychological pressure on technicians.

[0004] (2) Due to the lack of suitable cutting tools, the commonly used methods for cutting the entire section of soil column include knife cutting, wire sawing, deep digging with a pickaxe, etc. Although these methods can also remove the entire section intact, they are not only extremely dangerous, but also face the risk of breaking the section column if the operation is not careful. Therefore, a field collection framework, sampling kit and sampling method for the entire section of soil column with short sampling time and improved sampling success rate are proposed. Summary of the invention

[0005] In order to solve the above technical problems, the utility model proposes a whole section soil column field collection framework and sampling kit and sampling method which can shorten the sampling time and improve the sampling success rate.

[0006] A whole section soil column field collection frame and sampling kit, including a whole section profile shaping frame and a whole section profile cutting tool:

[0007] The whole section profile modification frame is a rectangular parallelepiped, and the whole section profile modification frame includes an upper steel plate, a right steel plate, a lower steel plate and a left steel plate connected in sequence; a plurality of steel cross braces are arranged in parallel between the left steel plate and the right steel plate; the upper steel plate, the lower steel plate, the left steel plate, the right steel plate and each steel cross brace are inwardly edged and have steel hemming on the outside;

[0008] The whole section profile cutting tool comprises a handle, a steel body, a steel foot pedal and a cutting head; the handle, the steel foot pedal and the cutting head are sequentially installed on the steel body along the length direction of the steel body, and the cutting head is sharpened.

[0009] The upper steel plate, the right steel plate, the lower steel plate, the left steel plate and a plurality of steel cross braces are fixed by welding.

[0010] Preferably, the upper steel plate, the right steel plate, the lower steel plate, the left steel plate and the plurality of steel cross braces are all made of stainless steel.

[0011] Preferably, leather covers are respectively provided at both ends of the handle.

[0012] A sampling method according to the whole section soil column field collection framework and sampling kit comprises the following steps:

[0013] S1: After trimming the soil observation surface, apply vaseline lubricant to the inside of the entire profile trimming frame;

[0014] S2: Keep the upper edge of the entire profile shaping frame parallel to the surface plane of the soil profile, and buckle the entire profile shaping frame to the soil;

[0015] S3: Use a rubber hammer to gently tap the stress points on the edge of the entire section profile modification frame to make the entire section profile modification frame completely embedded in the soil;

[0016] S4: Use a tool to trim away all the excess soil outside the entire section shaping frame;

[0017] S5: Gently remove the entire section shaping frame and embed the wooden specimen box on the soil;

[0018] S6: Insert the entire section cutting tool into the upper edge of the soil column that is nested in the wooden specimen box;

[0019] S7: Use the handle to control the cutting direction, and step on the steel pedal to cut the soil column from top to bottom;

[0020] S8: Lift the cut soil profile column together with the wooden specimen box horizontally, flatten it and seal it to complete the sampling.

[0021] Beneficial effects:

[0022] 1. Conventional collection methods require extremely careful shaping after the approximate soil profile size is delineated. The wooden specimen box is used for comparison and repair at the same time. Collapse and fracture problems are very common. Once collapse and fracture problems occur, the sampling time will be directly doubled. The utility model improves the soil profile sample collection due to the hard structure, fixed size and one-way blade, avoiding the problems of skewed soil columns and edge damage in the process of comparison and shaping using wooden frames in the past. After removal, it can be seamlessly nested directly into the wooden box to maintain the integrity of the soil column. Compared with the existing soil whole profile sampling method, the sampling process is greatly simplified;

[0023] 2. The whole section section cutting tool in the set of the utility model avoids the cumbersome cutting steps after the previous nesting of wooden boxes, such as deep digging with a pick, cutting with a chain saw and a profile knife, and other cumbersome processes. It directly cuts the whole from top to bottom, and the process is smooth and easy. The soil column is completely cut as a whole, reducing the risk of injury to operators using various complex tools such as knives, picks, chain saws, etc.;

[0024] 3. The conventional whole section sample sampling process needs about 1 hour to be collected smoothly (without breaking or collapsing). The use of this set can save time to less than 30 minutes. The use of this utility model set can greatly shorten the sampling time and greatly improve the one-time collection success rate.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1~Figure 2 The utility model is further described to better reflect the implementation process of the invention:

[0029] The existing technology of directly cutting, repairing and packing by stamping with a wooden frame has two major defects: (1) Since the soil is not a tightly connected whole structure and the wooden sampling frame cannot be directly embedded in the soil, the entire section of the soil column is repaired after a rough range is drawn. It generally faces problems such as fracture and collapse. This phenomenon is particularly significant in sections with shallow groundwater or high gravel content, which greatly increases the difficulty of collecting soil profiles. Repairing a half-collapsed section also causes great psychological pressure on technicians.
