Problems solved by technology

The accumulated silt not only affects flood discharge and farmland irrigation, but also seriously affects the quality of the water environment, aggravating the degree of eutrophication of the water body, and the quality of aquatic products is polluted. It is difficult to clean up the silt, difficult to transport, and even more difficult to accumulate. and pollute the land, it is also very easy to cause soil erosion and secondary pollution of water bodies
The large dredging ship has a navigation system, and the cost of removing the silt is too high to bear. This ship cannot enter shallow waters for construction. The navigation system under the ship is a common propeller, which is easily entangled by weeds and silt in the water and cannot rotate. Towed by the silt, the tugboat can do nothing, and the small and medium-sized dredgers have no navigation system and can only sail with the tugboat, which increases the overall cost of dredging

Embodiment Construction

[0016]In the picture, it consists of embankment, slope protection, spillway, cofferdam, gate, dam foundation, silt, water, reservoir bottom, barren beach, dumping ground, fence, support, hoarding, tree planting, cultivated land, water inlet, landfill The dredging mud utilization plan, the underwater mud (7) in the reservoir area, and the barren beach on the ground surface (10) were sampled in multiple places respectively, and the physical and chemical properties of the mud (7) were tested to provide data for the utilization of the mud (7). The surrounding environment is investigated and evaluated, and a silt (7) accumulation site (11) is set up at the high efficiency position. There are inorganic substances and minerals in the silt (7), and there is clay around the reservoir area. Jilin is a cold area, and the silt (7) is dredged in winter It cannot be constructed, and it is difficult to construct during the rainy season in summer. The dredging operation can only be carried out...

Abstract

The invention relates to a scheme for clearing away and using sludge. The scheme is composed of a dam, a gate, sludge, a dump, a hoarding and an air inlet, wherein the sludge clearing and using are bundled so as to resolve the current problems and eliminate the root causes; the sludge is conducted for physico-chemical analysis so as to provide scientific data for comprehensive use, a self-developed dredger with anti-winding propellers is adopted to clear away sludge, so as to slidingly throw off impurities and sludge in the water; during the sludge excavation in either a deep water area or a shallow water area, the dredger is provided with navigation, positioning and sonar systems to monitor underwater sludge and construction progress; the sludge and mud on the ground surface are treated as follows: the way of the crawler belt of a modified hooking machine is utilized to construct on the mud laid with an alloy pressing plate, and the sludge is transported to the dump, wherein a metal fence is arranged around the dump, supports are arranged in the fence, and screen gauzes are arranged on the fence, and the filtrated and air dried sludge is prepared into energy-saving environment-friendly multi-purpose functional bricks, so that land can be saved, and a planting area can be improved due to the fact that the sludge and clay are synthesized to landfill soil; furthermore, the water storage of a dredged reservoir area can be improved by 4 folds, and the qualities of water body and aquatic products can be obviously prompted; in addition, levelers towed by the dredger in the reservoir area is used for clearing up and fishing operations can be realized.

Description

technical field [0001] The patent of the present invention relates to the scheme that the silt accumulated in the reservoir area can be removed in an orderly manner and can be comprehensively developed and utilized as a resource. Background technique [0002] Domestic large, medium and small reservoirs were all built in the early days of the founding of the People's Republic of China. After nearly half a century of rainwater erosion, the silt accumulated in the reservoir area was more than 1 meter thick. During the rainy season, the river bed in the upper reaches of the reservoir area is full of silt, flooding the crops, and the crops fail and the production is reduced. Due to the lack of water to irrigate large areas of high-quality paddy fields, they had to be replanted into dry fields. Not only did the rice yields decrease, but sometimes the planting seasons passed, so they had to be abandoned and turned into barren fields. The summer drought caused the farmers to wither ...
