Embodiment Construction

[0015] see figure 1 , in the downstream of the river channel 4 every 300m~500m, a part of the river channel is dug deep mechanically or manually to form a silting tank 2 with a length of 6~8m and a depth of 1~2m, and a rubber dam 1 is built behind the silting tank to improve the silt Settlement conditions. Build a mud storage tank 5 on the bank at the depth of the river channel. The mud storage tank is solidified with brick rubble, and an anti-seepage membrane is laid on the bottom of the mud storage tank. The volume of the mud storage tank is 50m 3 ~200m 3 between.

[0016] Every three to six months in the river channel, dredging pumps are used to pump the silt from the deep excavation of the river channel into the mud storage tank. After the mud storage tank dries up, it is transported to other places for landfill. Usually, the sludge is treated in a concentrated manner after the moisture content of the sludge in the sludge storage tank is lower than 30%.

Abstract

The invention discloses a method for assisting in fixed-point dredging of a black and odorous watercourse through rubber dams. The watercourse is excavated every a section of distance, the rubber dams are constructed in the deep pits, mud storage ponds are constructed at the bank of the watercourse, the accumulated mud in the excavated positions of the watercourse is pumped into the mud storage ponds through a dredging pump every period of time according to the particular conditions of the watercourse, and the mud is processed in a concentrated mode after being dried naturally. The method is a fixed-point dredging technology which is simple, practical, low in cost and high in maneuverability.

Description

technical field [0001] The invention belongs to the dredging technology of river channels, in particular to the technology of utilizing rubber dams to assist fixed-point dredging of black and odorous river channels. Background technique [0002] With the development of social production, the water quality of rivers all over the world is facing different degrees of pollution from industry, agriculture, life and other aspects. River pollution is one of the environmental problems that is currently receiving increasing attention. Due to the presence of a large number of pollutants in the water body, the concentration of dissolved oxygen in the water body is reduced or even zero, resulting in black and smelly river water and the extinction of fish and shrimp. Polluted rivers not only lose resource function and use value, but also seriously damage the surrounding environmental landscape, and even endanger the health of river residents. At present, the seven major river basins in ...
