Description
Technical field
The present invention relates to port and pier desilting equipment and job practices thereof.
Background technology
The alluvial of harbour basin can influence the utilization rate of port berth.For the alluvial of wharf apron, can use traditional dredging plant to carry out desilting, yet just can not use traditional dredging tool to remove to the deposit of bottom, pile foundation wharfs.Desilting is a special dredging works between the pile group under the long piled wharf platform, needs to use special desilting equipment.Expensive from the desilting equipment of external introduction, and its combination property is configured with tangible incompatibility to the soil property of different regions.Active service desilting equipment ubiquity energy consumption height, work efficiency is low, concentration of hydraulic mixture is low, function singleness, and depth of water bad adaptability is to defective such as the compliance of soil property is relatively poor.The harbour desilting equipment that uses mainly contains miniature reamer head dredger, slush pump at present.Have the break ground dredger of termination of miniature reamer and be applicable to that the depth of water is less than the shallow water condition of 10m, but in case run into the depth of water greater than the desilting problem under water of 10m, this equipment will run into complex structure, the control difficulty is big, efficient is not high and the construction cost problem of higher, therefore, when carrying out the deep water desilting, need use relatively large equipment to support.Use diving slurry pump to carry out desilting, though have the equipment simple and flexible, be not subjected to the depth condition restriction, advantage such as the folk prescription cost is lower, also the existence relatively poor and planeness problem more rambunctious under water of ability of breaking ground.In order to address the above problem, research and development one cover can improve diving slurry pump the break ground efficient suction sand of ability and efficiency of construction and the device of desilting, is extremely important.
Summary of the invention
The problem that the present invention need solve is a kind of desilting facility of research and development and dredging method thereof, improves the efficiency of construction of carrying out desilting under harbour.
Technical scheme of the present invention adopts high-pressure hydraulic pump, diving slurry pump, the desilting head, nozzle, it is characterized in that the combination of high-pressure hydraulic pump and diving slurry pump, the diving slurry pump lower end connects the desilting head, desilting head bottom is tapered and have a suction inlet, be provided with the transition water tank on the top of desilting head, the high-pressure hydraulic pump delivery port connects the transition water tank inlet by tube connector, the transition water tank connects the high-pressure flush water tank that is contained in the desilting centriciput by tube connector, the high-pressure flush water tank has many water pipes vertically to lead to desilting head bottom, nozzle is equipped with in the water pipe lower end of leading to desilting head bottom, the uniform high-pressure flush nozzle horizontal by 45 ° at high-pressure flush water tank edge; The construction sequence of desilting facility is after by the desilting platform that has hanging device the desilting facility being placed earth surfaces, start high-pressure hydraulic pump, carrying out vertical and horizontal high-pressure flush breaks ground, form mud, start diving slurry pump then and inhale mud, mud is sucked by the desilting head, dredging tube by diving slurry pump drains into hopper, when desilting reaches designated depth, stops high-pressure hydraulic pump earlier, after stop diving slurry pump, again the desilting facility are sling, kept well pipeline, by mobile desilting platform, arrive next assigned address, repeat above-mentioned construction sequence.
Outstanding feature of the present invention is that high-pressure hydraulic pump and submersible dredge pump and desilting head are connected into an integral body, make the equipment globality stronger, operate more simple and convenient, the desilting head adopts vertical high-pressure flush comprehensive the breaking ground that combine with horizontal high-pressure flush, the desilting engineering adaptability is significantly improved, the desilting concentration of hydraulic mixture can reach 50%, even it is higher, productivity ratio is superior, and abundant removing shoal materials, minimizing workboat group, accelerating construction progress and raising efficiency of construction are all produced significant technique effect.
Description of drawings
What Fig. 1 represented is the structural representation of desilting facility under the harbour.
What Fig. 2 represented is the structural representation of desilting head.
What Fig. 3 represented is the schematic diagram of desilting platform matching operation.
The specific embodiment
The present invention's (seeing accompanying drawing) adopts high-pressure flush pump 1, diving slurry pump 2, desilting 3, nozzle, dredging tube, and high-pressure flush pump 1 is connected diving slurry pump 2 tops by a sleeve part 8 and flange, and the bottom of diving slurry pump 2 connects desilting 3 by flange.High-pressure flush pump 1 causes transition water tank 4 by water pipe 7 with water under high pressure, be connected to the high-pressure flush water tank 6 that is located at desilting 3 medium position by water pipe again, 8 water pipes of high-pressure flush water tank 6 usefulness are connected to desilting head bottom, 8 water pipes are installed 8 perpendicular nozzle 9, uniform 8 horizontal by 45 ° high-pressure flush nozzle 5 around the high-pressure flush water tank.The bottom of desilting 3 is tapered and have a suction inlet, advances sand window 10 offering 8 near the position of desilting head bottom above slightly around the cylindrical sand suction pipe simultaneously, can advance the sand amount by the open degree adjustment of adjusting the sand window.Desilting facility of the present invention are placed on earth surfaces by the desilting platform 12 that has hanging device 11, break ground by vertical high-pressure flush, make the desilting facility get in the soil layer rapidly, soil layer fragmentation around being incited somebody to action by horizontal high-pressure flush again, make slope failure, mud is sucked by desilting 3, and by diving slurry pump 2 and dredging tube dispatch to hopper.
The construction technology of harbour dredging operation is carried out according to the following steps:
1, selects for use and can free in and out under the harbour, and can lift the platform of this desilting facility, simultaneously at the wharf apron of desilting alongside lash ship, provide the power supply of platform desilting equipment with lash ship.
2, the desilting platform moves to construction point under the harbour, by the rope mooring on the pile of front and back.
3, fix the desilting platform after, transfer the desilting facility to the mud face, mud pipe is connected to hopper.
4, start high-pressure hydraulic pump, carry out vertical and horizontal high-pressure flush and break ground, formation mud starts submersible dredge pump then, inhales mud, and by mud pipe with slurry transportation to hopper.
5, observe the variation of mud discharging mouth concentration of hydraulic mixture when inhaling mud, concentration of hydraulic mixture reduces gradually, then slowly transfers the desilting facility; Too high as concentration of hydraulic mixture, then mention the desilting facility slightly, prevent vexed pump.
6, Dredging Construction reaches designated depth, then stops high-pressure hydraulic pump earlier, after stop submersible dredge pump, and the desilting facility are sling, keep pipeline well.
7, by mobile desilting platform, arrive next assigned address, repeat above-mentioned construction sequence.
