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
The invention belongs to channel cleanout technology, be specifically related to utilize rubber dam to assist the technology of black smelly river course fixed point desilting.
Background technology
Along with the development of social production, the water quality of river of countries in the world is all faced with the pollution in various degree from aspects such as industry, agricultural, lives.River pollution is one of current environmental problem day by day received publicity, and owing to there is a large amount of pollutant in water body, make dissolved oxygen concentration reduction in water body be even zero, cause river black smelly, fishes and shrimps disappear.The river polluted not only loses resource function and use value, and the environmental landscape around heavy damage, even jeopardizes the health of river resident.The large river basin of current China seven has been subjected to pollution in various degree all, particularly in section, 138 cities, the whole nation, the overwhelming majority flowing through busy areas is also subject to pollution in various degree, accounts for 38 % wherein lower than V class water body in country's " Environmental Quality Standard of Surface Water ".The black smelly problem how solving urban river has as early as possible become the task of top priority of urban environment work.Along with the continuous growth of socioeconomic development and urban population, in the world, urban water-body pollution problem is just obtaining paying close attention to more and more widely.In the most cities of China, the pollution situation of water body is quite serious, and most of city river is in black smelly state throughout the year.
Through accumulation year in year out, a large amount of pollutants precipitates and is accumulated in bed mud, is adsorbed on pollutant in sediment particles and pore water exchanges, thus outwards discharges pollutant, causes secondary pollution of water, causes river body long-term black smelly; A large amount of bed muds also provides the hotbed of breeding for microorganism, and actinomyces and blue algae are contributed maximum to black and odorous water.Organic matter in microbial decomposition bed mud produces foul smell, and meanwhile, black bed mud is also arrived water surface by the bubble supporting that the gas produced is formed, and causes black smelly.Therefore, in dredging waterway process, the cleaning of bed mud is necessary.But due to other a variety of causes after channel cleanout, mud can slowly be formed again.After accumulation after a while, the water quality in river course can be affected again, carry out a channel cleanout again, in bed mud scale removal process, consume a large amount of manpower and materials.
Summary of the invention
The present invention seeks to the defect for existing dredging technology, provide a kind of method utilizing rubber dam to assist the fixed point desilting of black smelly river course, is a kind of simple and practical, fixed point dredging technology that cost is low, workable.
Technical scheme of the present invention is as follows:
General thought of the present invention is: amass silt groove, long-pending silt flute length 6 ~ 8m, dark 1 ~ 2m by digging dark formation every 300m ~ 500m to river course in downstream, river course; Rubber dam is constructed at long-pending silt groove rear, control according to the shape of water level to rubber dam, improve silt settling condition, rubber dam is adjusted to dash state by dry season and the period when a river is at its normal level, to strengthen upper river repair function, and the wet season reduces rubber dam, play the function protected rubber dam and be beneficial to river course flood discharge; And build on bank, river course and store mud sump, river course dug by "removing sludge the mud accumulated depths at set intervals according to river course concrete condition and be evacuated to and store in mud sump, after the mummification of mud nature, mud is focused on.
Adopt method of the present invention, whole river bottom mud can be avoided to clear up, save expense, in addition, it also has the following advantages:
1, the present invention is specially adapted to conbined usage when the little upper reach of the water yield carries out restoration of the ecosystem, can increase the upstream depth of water in dry season, extends polluted water body and the time of contact of repairing structure, improves improvement condition.
2, the present invention uses rubber dam to improve sedimentation of suspension condition, can produce the discrepancy in elevation in natural river course, is beneficial to the natural reaeration process in river course.
3, the present invention utilizes and stores mud sump and focus on after mud mummification, decreases the expense of mud transfer and final disposal, reduces the running cost of desilting.
Accompanying drawing explanation
Fig. 1 is the river course plan view that the inventive method is implemented;
Fig. 2 was water state river course sectional drawing;
Fig. 3 is dash state river course sectional drawing.
In figure: 1. rubber dam; 2. long-pending silt groove; 3. rubber dam basis; 4. river course; 5. store mud sump.
Detailed description of the invention
See Fig. 1, in the downstream in river course 4 every 300m ~ 500m place by machinery or manually a river course part is dug deeply, formation is grown the formation of 6 ~ 8m, dark 1 ~ 2m and is amassed silt groove 2, constructs rubber dam 1 improve silt settling condition at long-pending silt groove rear.Dig bank, depths to build one store mud sump 5 in river course, store the brick slabstone of mud sump and solidify, store at the bottom of mud sump and lay an antiseepage film, store mud sump volume at 50m
3~ 200m
3between.
The mud at the river course place of deep-cutting, every three months to six months, to be evacuated to "removing sludge and to store in mud sump by river course, after storing the mummification of mud sump mud, is transported to other place's landfill.Normally wait store the mud moisture content in mud sump lower than 30% after mud is focused on.
Control according to the shape of water level to rubber dam, improve silt settling condition, see Fig. 2, the wet season reduces rubber dam 1, and river course 4 was water state, plays the function protected rubber dam and be beneficial to river course flood discharge.
See Fig. 3, in dry season and the period when a river is at its normal level, rubber dam 1 is adjusted to dash state, to strengthen upper river repair function.
