Abstract
The invention discloses a method for collecting shallow lake sludge, specifically a method for collecting sludge in a shallow lake like Lake Taihu, wherein longitudinal subaqueous furrows and transverse subaqueous furrows are excavated at the bottom of the lake at first; there are more than two longitudinal subaqueous furrows and more than two transverse subaqueous furrows, respectively; and the longitudinal subaqueous furrows and the transverse subaqueous furrows both are arranged at equal intervals; and then the sludge in the subaqueous furrows is suctioned out regularly by means of a sludge suction platform with a sludge suction pump. With this method, the dredging effect on the heave pollution sludge can be improved; and lake water secondary pollution produced by disturbing the bottom of the lake in the conventional dredging manner is avoided.
Description
Technical field
The present invention relates to a kind of silt displacement method.Specifically, be the method that is used for collecting mud in shallow lake such as the Taihu Lake.
Background technology
In recent years, along with the quickening of process of industrialization, the thing followed has also been come pollution to river and lake zone, makes that the water quality eutrophication degree of shallow lake in Taihu Lake and so on is higher, and water ecological environment is destroyed, and generally deposits seriously in the lake in the whole nation.For improving the water ecological environment of Taihu Lake and so on shallow lake, just must carry out desilting to the shallow lake in Taihu Lake and so on.At present, being used for to the method that shallow lake carries out desilting is to adopt to stir Suction Dredger.Adopt this Suction Dredger that stirs when operation, need be in the lakebed zone operation comprehensively of desilting, workload is bigger.Particularly some lakebed zone mud is not dark, stirs the formula dredge boat when operation after making, the efficient of removing the lakebed mud scum is very low.And adopt this mode desilting, the mud scum generation that can to lakebed, especially float over the mud upper strata is than big disturbance, and mud scum is rich in pollutant, stirring can make pollutant discharge, and therefore can bring secondary pollution to lake water, thereby influences the effect of removing lake pollution thing.
Summary of the invention
The problem that the present invention will solve provides a kind of method of collecting shallow lake mud.Adopt this method, can improve effect that desilting especially removes the heavily contaminated mud scum, avoid the lake water secondary pollution.
For addressing the above problem, take following technical scheme:
The method characteristics of collection shallow lake mud of the present invention are may further comprise the steps:
Earlier at lakebed excavation vertically furrow and laterally furrow under water under water, this vertically under water furrow and laterally under water furrow be respectively more than two, and vertical, horizontal under water furrow all be equidistant layout.
Utilize the suction mud platform interior mud sucking-off of furrow under water regularly that has dredge pump again.
Wherein, vertically the spacing between furrow is 50 ~ 500 meters under water, and laterally the spacing between furrow is 50 ~ 500 meters under water.
Said dredge pump is a multitube vacuum dredge pump.
Said vertically under water the furrow width and the degree of depth be respectively 10 ~ 30 meters and 1 ~ 3 meter, it is said that laterally the furrow width and the degree of depth are respectively 10 ~ 30 meters and 1 ~ 3 meter under water.
Take such scheme, have the following advantages:
Can find out by such scheme because the present invention is at lakebed excavation vertically furrow and laterally furrow under water under water, this vertically under water furrow and laterally under water furrow be respectively more than two, and vertical, horizontal under water furrow all be equidistant layout.Though lake current no matter be the lake current of that direction, can drive all that the mud of lakebed, especially mud scum flow to vertically under water furrow or laterally under water in the furrow because the effect of wind direction exists uncertainly.During desilting, only need to vertical, horizontal under water the mud in the furrow carry out dredging operation, and do not need lakebed desilting district is carried out comprehensive operation, thereby greatly reduce workload, improved desilting efficiency data.Because this dredging method is to utilize the suction mud platform have dredge pump regularly with the vertical, horizontal mud sucking-off in the furrow under water.During dredging operation, the import that only needs dredge pump through pipeline and vertical, horizontal under water the mud in the furrow contact, in suction mud process, mud, the mud scum that especially floats over the mud upper strata can be by disturbance, thereby has avoided secondary pollution that lake water is brought.
The specific embodiment
Below in conjunction with embodiment the present invention is done further explain:
Embodiment one
Three of regional lakebed excavations that need earlier desilting in Taihu Lake are the horizontal furrow under water of furrow and three under water vertically, these three vertically under water furrow and three laterally under water furrow all be equidistant layout.Wherein, vertically under water the spacing between furrow and laterally under water the spacing between furrow be 50 meters, vertically width and the degree of depth of furrow are respectively 10 meters and 1 meter under water, horizontal width between furrow under water and be respectively 10 meters and 1 meter deeply.
Afterwards, utilize the suction mud platform (or dredge boat) that has dredge pump every to the silt displacement in vertical furrow under water and the horizontal furrow under water once at a distance from three months.Dredge pump wherein is a multitube vacuum dredge pump.
Embodiment two
Five of regional lakebed excavations that need earlier desilting in Taihu Lake are the horizontal furrow under water of furrow and five under water vertically, these five vertically under water furrow and five laterally under water furrow all be equidistant layout.Wherein, vertically under water the spacing between furrow and laterally under water the spacing between furrow be 250 meters, vertically width and the degree of depth of furrow are respectively 20 meters and 2 meters under water, horizontal width between furrow under water and be respectively 20 meters and 2 meters deeply.
Afterwards, utilize the suction mud platform (or dredge boat) that has dredge pump every to the silt displacement in vertical furrow under water and the horizontal furrow under water once at a distance from 6 months.Dredge pump wherein is a multitube vacuum dredge pump.
Embodiment three
Ten of regional lakebed excavations that need earlier desilting in Taihu Lake are the horizontal furrow under water of furrow and ten under water vertically, these ten vertically under water furrow and ten laterally under water furrow all be equidistant layout.Wherein, vertically under water the spacing between furrow and laterally under water the spacing between furrow be 500 meters, vertically width and the degree of depth of furrow are respectively 30 meters and 3 meters under water, horizontal width between furrow under water and be respectively 30 meters and 3 meters deeply.
Afterwards, utilize the suction mud platform (or dredge boat) that has dredge pump every to the silt displacement in vertical furrow under water and the horizontal furrow under water once at a distance from 12 months.Dredge pump wherein is a multitube vacuum dredge pump.
