Embodiment Construction
[0037] The present invention provides an all-round observation device and method for bank scour and collapse. The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.
[0038] Fig. 1(a) is a front view of the device structure of the present invention; Fig. 1(b) is a top view of the device structure of the present invention. The all-round observation equipment for embankment erosion and collapse consists of a sliding tank box, a straight water tank, a plate box and a pushing device.
[0039]The sliding tank box is used to hold embankment soil; the left side plate 1031 of the tank box and the right side plate 1032 of the tank box are fixed on the first fixed platform 501, wherein the left side plate 1031 of the tank box and the right side plate 1032 of the tank box It is a transparent glass plate, and the erosion and collapse of the embankment can be observed through the two side plates; a thin steel...

The invention pertains to the technical field of characteristic tests of hydraulics and rock and soil mechanics and particularly relates to an omnibearing observation apparatus of bank scouring and slumping conditions, which consists of a slide-type groove tank, a straight sink, a panel box and a push device. A bank model is made in the slide-type groove tank and then pushed to an experiment position preset in the straight sink. Then water current is served for scouring the bank and when in scouring, the slide-type groove tank is continuously pushed forwards and the omnibearing observation iscarried out to the conditions of bank scouring and slumping till the bank is slumped. The omnibearing observation can be carried out to the process of bank scouring and slumping and then sediment concentration at the side of a riverway bank can be obtained by monitoring the change of the shape sizes of sections; the route of bank slumping can be directly observed and video recording can be carried out to record the extending process of the land sliding line of bank slumping.
Description
technical field [0001] The invention belongs to the technical field of hydraulics and rock-soil mechanics characteristic testing, and in particular relates to an all-round observation device and method for bank scour and collapse. Background technique [0002] The embankment collapsed under the action of water erosion, and there was a landslide surface, which was a landslide line in cross-section. This landslide line is of great significance in landslide research. In the initial stage of the landslide, the landslide line formed at the bottom or in the middle and gradually extended upward without penetration; as the landslide continued, the landslide line finally extended to the top surface, forming a through crack, that is, a complete landslide body was formed. If this landslide line extends to the outside of the embankment, it will cause the collapse of the entire embankment, eventually causing floods. Therefore, the research on this slip line is of great significance in e...
