Problems solved by technology

At the same time, the larger size of the soil profile will not only increase the excavation workload and affect the work progress, but also increase the damage compensation fee for young crops caused by the profile and spoil land occupation; when excavating the profile in the paddy field, the paddy field will be damaged The plow bottom layer of the soil caused water leakage in the paddy field, and it was difficult to obtain the support of the local people for the excavation of the soil profile.

Abstract

The invention discloses a soil profile sampling structure and an excavation method thereof. A soil profile comprises a square deep pit (1) and a square shallow pit (2), which are distributed at two-stage ladder-like manner, wherein the length, width and depth of the square deep pit (1) are respectively 60cm, 50cm and 100cm; the length, width and depth of the square shallow pit (2) are respectively 60cm, 50cm and 40cm; a sampling area (3) is arranged on one inside surface of the square deep pit (1); 50cm spoil areas are arranged outside the square deep pit (1) and the square shallow pit (2) respectively. The square deep pit (1) and the square shallow pit (2) are alternately excavated by adopting a T-shaped excavation head, a round shovel blade head and a trapezoidal shovel blade head in a matching manner. The soil profile sampling structure and the excavation method have the advantages that the profile space is smaller than the profile spaces in traditional methods; the structure is simpler; the sampled section is vertical, thus facilitating finishing, soil profile observation and sampling; the floor area can be obviously reduced, the loss can be reduced, the manpower, material resource and financial resource inputs can be reduced and the excavation time can be saved.

Description

technical field [0001] The invention relates to a soil profile sampling structure and an excavating method thereof, belonging to the field of soil sampling methods. Background technique [0002] As we all know, soil investigations in the field of soil science mainly adopt field surveys and sampling measurements, and soil sample collection is mainly completed by soil drilling and soil profile sampling. The soil auger soil extraction method is suitable for areas with normal landforms and karst areas with low soil gravel content. However, in karst areas, the soil gravel content is often high, and it is difficult to sample with soil augers, especially for deep soil sampling. Therefore, in the process of soil investigation and research in karst areas, soil profile sampling method is the best method for soil sample collection. [0003] The traditional method is suitable for excavating shallower soil profiles, but for soil profiles of 50-100cm or even deeper, due to the limitation...
