Background
The bottom mud is usually a mixture of clay, silt, organic matters and various minerals, and is formed by depositing on the bottom of a water body through long-term physical, chemical and biological actions and water body transmission. The sediment with the thickness of 0 to 15 cm on the surface is called surface sediment or semi-suspension sediment, and the sediment with the thickness of more than 15 cm is called deep sediment. The surface sediment can be sampled by a Grab sampler (Grab sampler) or a drill sampler (Core sampler), the deep sediment can be sampled only by a drill sampler, and the river sediment can be sampled by combining the hydrological section of the hydrological station with the test of bed load and suspended load. The sampling point should be Zhonghong Deng and two sides sparse. The sampling times are based on the principle of controlling the erosion-deposition change process of the river channel section, and the dry period is more than the flat period and the flood period. When water pollution investigation is carried out, in order to comprehensively know the water pollution condition and the change of the water pollution condition, a contrast section, a pollution section and a purification section are respectively arranged at the upstream of a pollution source and a river channel far away from the pollution source. The sampling point and the sampling times on each section depend on the section width and the contamination condition. Small rivers or river channels with light pollution can be few, and big rivers and river channels with heavy pollution are more, so that the principle of the migration condition of bottom mud and the change process of pollutant accumulation can be found out.
However, the existing grabbing type sampler for sampling the semi-suspended sediment is used for grabbing the sediment at a designated position through self gravity, the falling speed of the sampler is not controllable, deep sediment is easily lifted, and the sediment is mixed into the semi-suspended sediment, so that the collected semi-suspended sediment sample is impure, the subsequent detection effect is poor, and no device capable of effectively preventing the deep sediment from being lifted exists.
