Description
Technical field
The present invention relates to harbor approach and coastal engineering and get the device and the job practices thereof of sand construction.
Background technology
At present hydraulic reclamation epeirogenetic engineering to get the sand operation general all by traditional dredge boat, the hydraulic fill sand that directly adheres to specification such as dredging plants such as trailing suction hopper dredger, cutter suntion dredger, suction dredger and grab boats from submerged digging.Along with the order benefit of coastal extensive hydraulic reclamation epeirogenetic engineering increases; Reduce day by day in the coastal waters operational sand in top layer source under water; And the chiltern in sand source, offshore area is often in the majority with the powder fine sand, and the part chiltern is difficult to satisfy the designing requirement of hydraulic reclamation engineering, and dredge boat when getting sand efficiency of construction not high.In order to seek sand source preferably, often need outside tens kilometers, transport, increased difficulty of construction like this, reduced efficiency of construction, the risk that has increased cost simultaneously and far caused because of road.Existing suction-type dredge is to use in the cabin pump to get sand through putting to the sand suction pipe at the bottom; Only rely on the vacuum of pump in the cabin itself to inhale sand during work; It is lower to inhale sand concentration, and therefore suction-type dredge often need dispose in 9 cabins pump and constructs simultaneously, and efficiency of construction is not high.A large amount of engineerings of reclaiming fields from the sea, the hydraulic reclamation amount is huge, and chiltern is had relatively high expectations, and with suction-type dredge sand is drawn onto on the cargo ship usually, and cargo ship is transported to by the blast ship, is transported to construction part by many slush pumps on the blast ship, and its haul distance is basically all more than 20km.This confession sand technology reduces haul distance if can raise the efficiency, and gets sand nearby the sand in sand inferior source is used, and then supplies the sand cycle to shorten greatly, and efficiency of construction also can be improved largely.
Summary of the invention
The problem that the present invention need solve is device and the job practices thereof that research and development one cover can efficiently be got sand, gets the sand efficiency of operation to improve single-point list pump.
Technical scheme of the present invention adopts high-pressure hydraulic pump, nozzle, diving slurry pump, suction cutter, sediment transport pipe; It is characterized in that the combination of high-pressure hydraulic pump and diving slurry pump; Diving slurry pump connects cylindrical suction cutter, is provided with the transition water tank at suction cutter and dredge pump junction, is provided with the high-pressure flush water tank at the cylindrical sand suction pipe medium position of suction cutter; The transition water tank is connected by 4 water pipes with the high-pressure flush water tank; The high-pressure flush water tank has 8 water pipes through to the suction cutter bottom, and on these 8 water pipes, adorns nozzle, and 8 horizontal by 45 ° high-pressure flush nozzle also is installed on the high-pressure flush water tank; The transition water tank inlet is connected to the high-pressure hydraulic pump at top through water pipe, the suction cutter bottom tapered and the bottom with inhale the chamber around suction inlet is arranged; With hanging device said apparatus is placed the silt surface; Break ground through vertical high-pressure flush; Device is got into rapidly in the soil layer, by horizontal high-pressure flush that soil layer all around is broken again, make slope failure; By suction cutter the mud that forms is sucked, and through diving slurry pump and the dispatch of sediment transport pipe to the appointed place.
Outstanding feature of the present invention is that high-pressure hydraulic pump and submersible dredge pump and suction cutter are connected into an integral body, makes the equipment globality stronger, operates more simple and conveniently, and economy and compliance are significantly improved.Adopt vertical high-pressure flush comprehensive the breaking ground that combine with horizontal high-pressure flush; Concentration of hydraulic mixture when getting the sand operation can reach 50%, even higher, and productivity ratio is superior; Can improve the suction slurry ability of slush pump; Can all produce considerable influence to making full use of existing sand source, minimizing workboat group, accelerating construction progress and raising efficiency of construction well for dredging workss such as hydraulic reclamation is got the sand engineering, the engineering of reclaiming fields from the sea provide a sand approach of getting of more imitating, application value is high.
Description of drawings
What Fig. 1 represented is the structural representation of getting the sand device.
What Fig. 2 represented is the structural representation of suction cutter.
The specific embodiment
The present invention's (seeing accompanying drawing) is installed in the device top with high-pressure hydraulic pump 1, is connected diving slurry pump 2 with flange by pipe fitting 8, connects the suction cutter 3 of bottom again through flange.High-pressure flush causes transition water tank 4 by high-pressure hydraulic pump 1 through water pipe 7; Be connected to the high-pressure flush water tank 6 of suction cutter medium position again through 4 thick water pipes; Connect high-pressure water tank 6 through to the suction cutter bottom through 8 thin conduits again, these 8 thin conduits are installed 8 perpendicular nozzle 9; Be evenly equipped with 8 horizontal by 45 ° high-pressure flush nozzle 5 around the high-pressure flush water tank.The bottommost of suction cutter 3 is tapered and have suction inlet, and offering 8 advances sand window 10 all around along cylindrical sand suction pipe in the position of while above omiting near the suction cutter bottom, can adjust into sand amount through the open degree of adjusting the sand window.With hanging device said apparatus is placed the silt surface; Break ground through vertical high-pressure flush; Device is got into rapidly in the soil layer, by horizontal high-pressure flush that soil layer all around is broken again, make slope failure; By suction cutter 3 mud that forms is sucked, and through diving slurry pump 2 and the dispatch of sediment transport pipe to the appointed place.
Construction technology when this covering device is got the sand operation is carried out according to the following steps:
1, the suction-type dredge that hanging device is housed and originally gets the sand device arrive to be specified and to be adopted the sand point, will get the lifting of sand device and slowly transfers to the mud face, and for improving the sand extracting efficiency of every ship, every ship can be equipped with 4～8 and get the sand device, transfers simultaneously and gets sand.
2, open high-pressure hydraulic pump, adjust the high-pressure flush system operational parameters, carry out vertical and horizontal high-pressure flush and break ground, open submersible dredge pump then, get the sand operation.
3, submersible dredge pump is drawn the back with mud and is delivered to hopper through mud pipe.
4, get after the sand operation accomplishes, stop high-pressure hydraulic pump earlier, after dredge pump goes out clear water, close the dredge pump power supply, the device of slinging is kept pipeline well, prepares subjob down.
