Abstract

The invention discloses a floating plug type bulkhead gate, which comprises two embodiments, which are respectively an integrated floating plug type bulkhead gate and a combined floating plug type bulkhead gate, wherein the integrated floating plug type bulkhead gate comprises a floating plug gate, a submersible pump, a ballasting and support cantilevers, wherein a plurality of water chambers are formed in the floating plug gate, the ballasting is arranged in the bottom water chambers; the submersible pump is equipped in the water chambers; the bulkhead gate can be further designed as the combined floating plug type bulkhead gate if the floating plug type bulkhead gate is excessive in size or inconvenient to manufacture or transport; the combined floating type comprises a water retaining floating body, a supporting floating body, a connecting floating body and two telescopic devices. The floating plug type bulkhead gate provided by the invention can be used for plugging water inlets of free flow water channels of water resources and hydropower engineering, is simpler and easier than conventional bulkhead gates and low in cost; besides, excavation of a gate slot, additional arrangement of a support, the assembly of embedded parts, the pouring of a bent frame and allocation of a gate hoist are not needed if the floating plug type bulkhead gate is additionally arranged, underwater construction projects are avoided, restriction of arrangement of an original building is basically eliminated.

Description

technical field [0001] The invention relates to a floating plug type maintenance gate, which belongs to the technical field of maintenance gates. Background technique [0002] Jiangkou Hydropower Station is located near Jiangkou Town, Xinyu City, Jiangxi Province, with a total storage capacity of 890 million cubic meters, which is an incomplete annual regulating reservoir. The normal storage level of the reservoir is 72.00m, the design flood level is 74.40m, the check flood level is 76.00m, and the stagnant water level is 65.70m. The elevation of the weir crest of the spillway on the left bank is 64.00m, and there are 3 holes in total. The width of the orifice is 12m, and the height is 6m. There is a parapet on it, and the discharge is controlled by submerged arc gates. The arc door has been in operation for 50 years, with serious aging and deformation, obvious corrosion and water leakage, posing safety hazards and need to be replaced. Since the stagnant water level is hig...
