Device for dredging sludge by dredger

Abstract

The invention relates to a device for dredging sludge by a dredger. The device comprises a suction dredger which is used for transmitting the sludge in a riverway or a lake into a port of a waterborne floating tube through a sludge suction pump; the other port of the waterborne floating tube is communicated with a shore tube bridged over the land; the device is characterized in that: the length of the waterborne floating tube is limitless and the waterborne floating tube consists of a plurality of sections; and any two adjacent sections of the waterborne floating tube are connected with each other through a booster pump. In the device, as the waterborne pressurization of the booster pump is assorted with the suction dredger, the extraction and the transportation of sludge form line production; therefore, the process flow is simplified, the investment of equipment and labor is reduced, and most importantly, the working efficiency of engineering is improved greatly and the daily management work and the construction cost are reduced at the same time; and secondary pollution of barge transportation to the periphery environment can be avoided.

Description

Device for dredging sludge through dredger Technical field The invention relates to a lake sediment dredging and conveying device, in particular to a device for dredging sludge through a dredger. Background technique The sludge removal of existing lakes or rivers is usually done by dredgers. In conventional construction methods, grab suction dredgers, dredgers and a certain number of transport barges need to be used for supporting construction. On the one hand, due to the large number of input equipment and construction personnel, the corresponding production cost is also high. On the other hand, each step of suction, digging and transportation has a shorter time, which more or less affects the superior and subordinate processes, resulting in Low operating rate. In addition, because the dredging site is too far away from the shore or the mud yard, it cannot be directly transported to the accumulation point of the silt on the shore by the pressure pump, so it exceeds the row ...

AI Technical Summary

Problems solved by technology

On the one hand, due to the large number of equipment and construction personnel, the corresponding production costs are also high. On the other hand, each step of suction, excavation, and transportation has a short time, which more or less affects the processes of the upper and lower levels, resulting in low productivity

In addition, because the dredging site is too far away from the shore or the mud discharge field, it cannot be directly transported to the accumulation point of the silt on the shore through the pressure pump, which exceeds the discharge distance of the general dredger, and can only be transported back and forth by traditional transport ships. , the capacity of the transport barge is limited, and the round-trip time difference has become an important factor limiting the efficiency of the dredger operation

It not only lengthens the construction period but also increases a large amount of engineering costs. This disadvantage is currently a problem widely encountered in the dredging of large lakes in China.
