Embodiment Construction

[0024] The present invention will now be further described in detail in conjunction with embodiments, so as to facilitate the understanding of the purpose, technical solution and effects of the present invention.

[0025] This embodiment provides a ball valve type silted soil undisturbed soil sample sampling device (hereinafter referred to as the sampling device), such as figure 1 As shown, it includes a handle 1 , a rotating shaft 2 , a counterweight bearing platform 4 , a pipe shoe 8 , an opening and closing blade 7 , a sealing disc 9 and at least one extension rod 3 . The handle 1 is movably connected to the upper end of the rotating shaft 2, and the handle 1 can rotate around the rotating shaft 2 so that the handle 1 is parallel or perpendicular to the ground. The lower end of the rotating shaft 2 is screwed to the upper end of the extension rod 3 , and the lower end of the extension rod 3 is screwed to the counterweight bearing platform 4 . Therefore, the length of the s...

Abstract

The invention discloses a ball valve type deposited soil undisturbed soil sample sampling device and a sampling method thereof. The device comprises a handle, a rotary shaft, a counterweight bearing table, a shoe, an openable and closeable blade, a shaft cover and at least one extension rod, and further comprises a plurality of counterweights. The using method of the device comprises the following steps: 1) determining the pitch number of the extension rods and the number of the counterweights, passing the free end of a traction rope to symmetrical through holes of the counterweights along grooves of the counterweights, rotating the handle to be vertical to the ground, sleeving the required counterweights on the extension rods by virtue of the handle, and rotating the handle to be parallel to the ground; 2) putting the sampling device into water, maintaining the water flow channel smooth and inserting the shoe into a mud soil layer to sample; 3) lifting the traction rope and closing the lower end opening of the shoe; 4) unloading the counterweights and taking out a sludge sample. The device disclosed by the invention is simple in structure, convenient to detach and easy to carry, and maintains the original characters of the sludge sample, so that the device is particularly suitable for interface sampling with relatively high river level and water depth of lake.

Description

technical field [0001] The invention belongs to the technical field of sampling equipment for water environment monitoring, and in particular relates to a ball valve type silted soil undisturbed soil sample sampling device, and also relates to a sampling method using the sampling device. Background technique [0002] The amount of silt deposited in rivers, lakes, and urban landscape areas is huge. River silt not only reduces the fluidity of water, but also leads to a decrease in the self-purification ability of the water body, and even becomes an internal pollution source of the river. Therefore, water environment monitoring and river dredging work are particularly important. River silt is different from ordinary clay. It is rich in pollutants and nutrients. In order to determine which method to use for river dredging, it is necessary to study the composition content of different silts and analyze their characteristics. Representative samples of silt are obtained. It is very...
