Automatic coastal dredging, intercepting and pollutant discharging water conveying port

Abstract

The invention provides a multi-layer multi-hole intercepting and pollutant discharging water conveying port comprehensive structure. A water conveying channel is built along a coastline, the water conveying channel has advantages that construction cost is low, conveying distance is long, land acquisition coordination is easy, however, passing of a port along the coastline is the most difficult. According to the multi-layer multi-hole intercepting and pollutant discharging water conveying port comprehensive structure, the bottommost layer is provided with a fresh water conveying layer and can pass through a port channel by means of a box culvert, a tunnel and the like, the culvert top or the tunnel top is located below the channel water level depth line, and a water conveying gate is arranged and used for segmented pollutant interception, segmented water level regulation and storage, automatic dredging and the like of the long-distance water conveying channel; the middle layer is provided with a channel layer, is provided with a flood discharge tidal gate and is a navigation layer; and the dyke top is provided with a bridge layer, and the requirements of vehicle traffic are met. Onthe plane, if flood and tide prevention gates or ship locks exist at the port, the flood and tide prevention gates or the ship locks are arranged close to the river channel side and are properly separated from a water conveying tunnel culvert, in this way, the whole port is arranged in a saving and separating mode, and meanwhile the comprehensive functions of water conveying, vehicle traffic, shipping, flood prevention, tide prevention, operation and maintenance, interception, pollution discharge, regulation and storage and the like are achieved.

Description

technical field [0001] The invention belongs to the field of water delivery engineering construction, and relates to a coastal automatic dredging, interception, sewage discharge and water delivery port structure. Background technique [0002] The earth's fresh water resources are extremely limited. Among all water resources, 97.5% are salt water, 2.5% of fresh water, and 87% are ice sheets, alpine glaciers and ice and snow in permafrost zones. It is difficult for humans to use them. What humans can really use is Rivers, lakes and a part of groundwater only account for 0.26% of the total water on the earth, and the distribution is uneven. 80 countries and regions, accounting for about 40% of the world's total population, suffer from severe water shortages, and 3.5 billion people face water shortages. For example, in Ethiopia in eastern Africa, the average altitude is 3000m. A puddle or turbid stream is also a very precious water source for residents. However, drinking it cau...

Problems solved by technology

Some rivers themselves are water-scarce basins, and sometimes there are problems with water quality. For example, the Huaihe River Basin in my country has a serious water shortage. At the same time, it is polluted by industrial point sources in upstream areas and agricultural non-point sources. kind, class even class to inferior Such conditions are not suitable for water transfer as a water source or water delivery channel
