Abstract

The invention discloses a layered sampler for suspended sediment for river engineering model tests, which comprises a plurality of single-layer sampling structures, baffles and cross bars, and the single-layer sampling structure is a cuboid structure with a cylindrical sampling bin in the middle , the single-layer sampling structure is vertically overlapped and combined to form a multi-layer sampling structure, the holed plate is provided with a circular sampling hole with the same diameter as the sampling bin mouth, and the number of sampling holes in the baffle plate is less than that of the sampling bin One, the upper ends of the front and rear baffles are connected by cross bars; the present invention also discloses a method based on the above-mentioned layered sampler, which can sample the effect of multiple layers of suspended matter at one time, greatly shortening the sampling time of suspended matter in river engineering model tests. time.

Description

technical field

[0001] The invention relates to the field of water conservancy experiments, in particular to a layered sampler for suspended sediment and a sampling method for river engineering model tests. Background technique

[0002] Suspended mass sampler is a commonly used sediment sampler in water conservancy projects. At present, there are two types of instantaneous type and time-integrated type. Among them, the most commonly used instantaneous sampler is the horizontal sampler. The body is a cylinder, the axis is parallel to the direction of water flow, and there are covers and springs at both ends. When sampling, the two covers are opened, and when the water flow is stable, the switch is operated to close the two covers at the same time to obtain instantaneous water samples. This kind of sampler is easy to operate and has strong adaptability; there are several types of time-integrated samplers, such as pressure-regulating chamber type, leather bag type, and bottle ...
