[0033]SeeFigure 1-4 , A sample collection device based on an in-situ pre-buried method before flooding of a reservoir, which includes a sample collection device frame structure and a sample collection device side plate structure; the sample collection device frame structure includes two parts , Respectively are the water flooded test box 1 at the lower part of the frame structure of the sample collection device and the slide rail 2 at the upper part of the frame structure of the sample collection device. The top frame of the water flooded test box 1 is provided with a guide groove 3, and the water flooded test box 1 Four sides are provided with inner side panels 11 of the water flooded test box, the inner side panels 11 of the water flooded test box are provided with uniformly distributed connecting holes 4, and the top four corners of the water flooded test box 1 are respectively fixedly connected with traction ropes 9; The side panel structure of the sample collection device incl...

Embodiment 2

[0039]The sample collection method of the sample collection device based on the in-situ pre-buried method before the reservoir drawdown zone is submerged includes the following steps:

[0040]Step 1: Divide the drawdown zone into n elevation intervals according to the requirements of the experimental design, and set different flooding times according to the experimental requirements and reservoir water level scheduling;

[0041]Step 2: After the fluctuating zones of different elevations are exposed, arrive at the pre-determined sampling location, and take out the n-elevation intervals of the divided fluctuating zones and the non-flooded area above the normal storage level of the reservoir and the flooded test box in sequence 1 For the original samples of the same size, put the taken original samples into the flooded test box 1 in turn;

[0042]Step 3: Pre-bury the flooded test box 1 with the original samples in situ in sequence, combine the other end of the traction rope 9 into one, number i...

Abstract

The invention provides a sample collection device and method based on an in-situ pre-burying mode before reservoir hydro-fluctuation belt submerging. The sample collection device comprises a sample collection device frame structure and a sample collection device side plate structure. The sample collection device frame structure comprises two parts, namely a water logging test box at the lower partof the sample collection device frame structure and a sliding rail at the upper part of the sample collection device frame structure, a guide groove is formed in a top frame of the water logging testbox, and water logging test box inner-layer side plates are arranged on four side surfaces of the water logging test box; communication holes which are uniformly distributed are formed in the water logging test box inner-layer side plates and traction ropes are fixedly connected to four corners of the top of the water logging test box respectively. The sample collecting device can be used for collecting the underwater soil sample of the reservoir hydro-fluctuation belt, and effectively overcomes the difficulty that the sample is inconvenient to collect underwater.

Description

Technical field[0001]The invention belongs to the field of experimental research on the drawdown zone of a reservoir, and specifically relates to a sample collection device and method based on an in-situ pre-buried method before the drawdown zone of a reservoir is flooded.Background technique[0002]my country has nearly 100,000 reservoirs with a storage capacity of 100,000 cubic meters and above, with a total storage capacity of about 932.3 billion cubic meters. They play multiple functions such as regulating river runoff, flood control, water supply, irrigation, power generation, shipping, and tourism. During the operation of the reservoir, due to the seasonal fluctuation of the water level in the reservoir area, the surrounding land is periodically inundated and exposed between the highest water level and the lowest water level.[0003]As the first ecological barrier for water bodies and land banks, the health of the hydro-fluctuating zone ecosystem is directly related to the safety ...
