High-pole type full-measuring-range hydrologic observation platform and construction and integration method thereof

Abstract

The invention discloses a high-pole type full-measuring-range hydrologic observation platform and a construction and integration method thereof. The platform comprises a hydrologic section foundationand a concrete or steel structure high pole, wherein installation holes, a repairing ladder, floater grooves, an instrument cabinet positioned on the top of the high pole and the like are reserved onthe high pole. By use of the platform, hydrologic observation can be carried out in a full measuring range without being affected by emergency water events, including sediment accumulation, reservoir(barrier lake) water overflowing and the like, various types of hydrologic observation equipment, including water level, flow, sediment, water quality and the like, can be integrated to a maximum degree, and hydrologic observation reliability and efficiency can be greatly improved. By use of the method, items, including water level, flow and the like, can be observed in the full measuring range, and the influence of a hydrologic observation building on water flow can be reduced to a maximum degree. The method can integrate most types of hydrologic observation equipment, including water level,flow, sediment, water quality and the like, the difficulty that different observation items need to construct different platforms is solved, and the platform has high universality. The method still can normally work when major disaster events, including dam break, barrier lakes and the like, happen.

Description

technical field [0001] The invention relates to an observation platform and a construction and integration method thereof, in particular to a high pole type full-scale hydrological observation platform and a construction and integration method thereof, belonging to the technical field of hydrological measurement. Background technique [0002] At present, commonly used hydrological observation platforms mainly include water level self-recording wells, non-contact water level or flow installation poles (towers), and hydrological observation platforms in rivers. [0003] The water level self-recording well adopts a float type water level gauge, which is stable in operation and high in reliability. However, the water level self-recording well has a large water blocking area, high investment in infrastructure, and it is difficult to cover the full range, especially for water emergencies (reservoir, barrier lake collapse). At the same time, it is difficult to integrate water leve...

AI Technical Summary

Problems solved by technology

The buoy-type hydrological observation platform uses buoys or small floating rafts, which change with the water level of the river, and has to rely on other facilities to observe the water level. At the same time, it is difficult to fix the position of flow measurement or sand measurement; the bottom-mounted hydrological observation platform is more affected by river sediment , the maintenance is difficult, the reliability is poor, and the observation items are extremely limited. Generally, only the flow velocity can be observed; the fixed hydrological observation platform needs to build large-scale buildings or structures in the river or on the bank slope, so it has the water level self-recording well phase Similar problems, high infrastructure investment and difficult full-scale, multi-element observation, not suitable for large and medium-sized rivers
