Deep cleaning construction method for channel side slope

Abstract

The deep cleaning construction method for the channel slope comprises the following steps that (1) the cavitation jet cleaning trolley is in place on the channel slope; (2) injecting water into the clear water tank; (3) carrying out deep cleaning operation on algae mud on the side slope of the channel; and (4) after the clean water in the clean water tank is used up, repeating the step (2). And (5) pouring the sewage collecting box after the sewage collecting box is filled with the algae mud mixture. And (6) the truck is driven to the operation site, the steps (1)-(5) are repeated, and the next cycle of operation process is carried out. The device is reasonable in design, easy to manufacture, low in cost and large in jet flow coverage area, the cleaning efficiency of the channel slope is improved, the service life of each part is longer, and the cleaning effect is greatly enhanced. The sewage collecting tank and the clean water tank are more reasonable in layout, the sewage collecting tank is large in size, the clearing operation construction process is environmentally friendly, the requirement for ecologically clearing the algae mud mixture is met, and the method has great significance in guaranteeing the channel water quality and water conveying safety.

Description

technical field [0001] The invention belongs to the technical field of water body environmental protection treatment, and in particular relates to a construction method for deep cleaning of channel slopes. Background technique [0002] For major water diversion projects that use channels, such as the South-to-North Water Diversion Main Canal, in addition to the growth of algae, a large amount of mud will adhere to the side slope of the channel, forming a mixture of algae and mud. The growth of algae and mud deposits on the side slope of the channel have seriously affected the quality of the water body. Algae in the water body can not only cause the water body to smell and turn green and black. The odor of most lakes and ponds is caused by the death of algae and the lack of oxygen in the water body. Caused by hydrogen sulfide, sulfur, ammonia and other substances, the dead algae deposits on the slope seriously affect the water quality. What is more serious is that harmful sub...

AI Technical Summary

Problems solved by technology

[0005]1. The casing adopts a special-shaped structure, the manufacturing process is cumbersome and the cost is high;

[0006]2. Although the elastic vertical connection component adopted can make the device close to the side slope of the channel with a certain pre-compression force, the force on the universal wheel is relatively large. large and easily damaged;

[0007]3. The three cleaning disc assemblies arranged in an obtuse triangle form cover a small area although there is no dead angle;

[0008]4. The high-pressure rotary joints are purchased from the market. Since they work in water and the working environment is harsh, the high-pressure rotary joints are easily damaged, which makes the rotation of the three nozzles difficult. Affect the cleaning effect;

[0009]5. The sewage suction pipeline adopts the sewage suction hose, which is wound on the sewage suction hose reel, and the sewage suction hose expands with the extension of the multi-stage hydraulic telescopic arm. Long or shrinkable, it is pulled or wound from the sewage suction hose reel. This structure is complicated and the operation is cumbersome. When the multi-stage hydraulic telescopic arm is extended or contracted, the sewage suction hose reel needs to rotate synchronously; the sewage collection box and cavitation The sewage suction pipes between the jet cleaning trolleys all use sewage suction hoses. Since a part of the rubber hose is wound on the sewage suction hose reel, the internal channel of the sewage suction hose is bent and the inner hole becomes flat, which causes the sewage suction hose to absorb sewage normally. During operation, there is a large resistance, which affects the effect of negative pressure suction;

[0010]6. The truck is equipped with algae-water separation device, sewage collection tank, sewage collection tank and clean water tank. The storage capacity of the dirty tank and clean water tank is small. After the dirty tank is full, the algae mud mixture needs to be dumped, and the cleaning operation must be interrupted frequently. The frequency of dumping the algae mud mixture by trucks is high, which affects the efficiency of the cleaning operation; in addition, the separation of algae and water The device needs power when it works, and consumes a lot of energy
