Description
Technical field
The present invention relates to a kind ofly be used for engineering dredging, deepwater dredging, the dredging of polluted water region bed mud, and the scraper blade type dredger that the bed mud in the hopper is promoted the input stockyard.
Background technology
In polluted water region,, therefore when contaminated waters is administered, must dredge the bed mud that contains a large amount of pollutants in these waters because 80% pollutant can be deposited in the bed mud.In the hydraulic engineering construction process,, also usually need carry out engineering dredging, deepwater dredging at the bottoms such as lakebed, riverbeds for the degree of depth in the unimpeded and waters that guarantees water channel.
Traditional dredging plant mainly is divided into two classes: the first kind is to become mud with the loosening bed mud of devices such as reamer, drag head, bucket wheel or hydraulic giant, aspirates and by pipeline mud is delivered to the stockyard and deposit, precipitate, dewater, solidify with pump again.When utilizing this kind equipment to dredge, because bed mud is subjected to serious stirring, the pollutant in the bed mud is diffused in the water once more, thereby secondary water is seriously polluted; In addition, the average mud content of general mud is no more than 20%, in order to dredge bed mud, needs to carry the mud that is five times in the bed mud volume, causes the dredging inefficiency; Deposit mud simultaneously and need take a large amount of places, also can bring a series of problem in the precipitation of mud, dehydration, solidification process, for example a large amount of contaminated surplus water are contaminated environment once more, and uncured mud causes the pedestrian to be strayed into depression, or the like, the dredging cost is further strengthened.
Second class is to put into hopper and be transported to the stockyard with grab bucket, chain bucket, scraper bowl lifting bed mud, dredge and lifting process in, overflow is scattered and disappeared a lot of, form muddy on a large scale district, main is when the bed mud in the hopper is discharged into the stockyard, generally to adopt the hydraulic reclamation method, promptly dash, aspirate, can form secondary water equally and pollute with water pump with hydraulic giant.
Along with in the dredging process to the further raising of environmental requirement, last century end, Italy PNEUMA.S.R.L has produced a kind of air-powered pump, this air-powered pump utilization is calmed the anger the mud that enters in the water-bed gas tank is discharged, step-down then, because the water surface is higher than the intake of gas tank, the mud that head pressure will get lodged in around the intake is pressed into gas tank, three gas tank alternations are arranged, control the process that moves in circles by one group of valve.The subject matter that this system exists is:
(1) when water is more shallow, head pressure is little, need set up vacuum pump, make equipment complicated, and polluted bed mud is much in the phytal zone;
(2) only be applicable to the sediment layer of bulky, bed mud must be contained suction inlet all the time, could obtain the mud of high concentration, in fact is difficult to satisfy all the time, and water on every side is very easy to be washed open to contain and pour in the jar, and concentration of hydraulic mixture is declined to a great extent;
(3) power consumption gross efficiency high, the transmission of calming the anger only is electrically-driven 1/6～1/7.
Summary of the invention
Problem at prior art exists the purpose of this invention is to provide a kind of dredging efficient height, construction cost is low, and can effectively prevent to produce the scraper blade type dredger that secondary water pollutes.
