Description
Technical Field
The utility model relates to a from lift-type platform with pile shoe, more specifically say, relate to a structure is washed to collection sand at self-lift type platform pile shoe top.
Background
Self-elevating ocean engineering platform is the core equipment that is used for realizing ocean resource development, like self-elevating drilling platform, self-elevating wind-powered electricity generation mounting platform, leveling platform etc. is laid to self-elevating rubble. When the self-elevating platform is used for standing operation in the ocean, pile shoes need to be inserted into the seabed and are deeply buried in mud and sand of the seabed. When the platform is to be returned to a floating state, the pile shoe needs to be pulled out of the seabed. In the process of pulling out the pile shoe, because the inclination angle of the top of the pile shoe is limited, silt with certain thickness is inevitably remained on the upper surface of the pile shoe after the pile shoe is pulled out from the seabed. If silt on the upper part is not treated, the pile shoe cannot be put in place, and great risk and uneconomical navigation exist for ship moving.
At present there are two kinds to the processing mode of remaining in pile shoe upper surface earth after pulling out the pile shoe:
1) And (4) manually cleaning soil remained on the upper surface of the pile shoe in the dock. This mode clearance time interval is long, remains the earth at pile shoe top behind the plug pile shoe of relapse a lot of, and the earth of upper surface can become very hard, and manual handling of docking is also very difficult, but also can increase the resistance of platform navigation in-process, reduces the economic nature of platform. If docked, the efficiency of the platform will be greatly affected and very high financial costs will be incurred.
2) The water flow flushing by the transfer has a good effect on very thin sand but has little effect on silt.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned defect that exists among the prior art, the utility model aims at providing a structure is washed to collection sand at self-elevating platform pile shoe top, through setting up the inside and outside adhesion of two sets of collection sand washing pipelines in order to destroy pile shoe and earth, both made things convenient for pile pulling, be favorable to pile shoe top earth to drop naturally again.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a sand collecting and flushing structure at the top of a pile shoe of a self-elevating platform comprises a high-pressure flushing water pipeline, a sand collecting and flushing port and a pile shoe external flushing pipeline;
the high-pressure flushing water pipeline is arranged in the pile shoe and the pile leg and is communicated with a high-pressure flushing pump of the self-elevating platform;
the sand collecting flushing ports are provided with a plurality of sand collecting flushing ports which are all arranged on the top surface of the pile shoe;
the pile shoe external flushing pipeline is arranged in a hull bottom plate of the self-elevating platform and is communicated with a high-pressure flushing pump of the self-elevating platform;
the water outlet of the external flushing pipeline of the pile shoe is aligned with the top surface of the pile shoe.
Preferably, a plurality of water outlets of the pile shoe external flushing pipeline are uniformly distributed around the circumference direction of the bottom plate of the self-elevating platform.
Preferably, a plurality of cabin penetrating sleeves matched with water outlets of flushing pipelines outside the pile shoes are uniformly arranged in the circumferential direction of a ship body bottom plate of the self-elevating platform.
Preferably, the water outlet of the flushing pipeline outside the pile shoe and the sand collecting flushing port are obliquely arranged.
The utility model provides a structure is washed to collection sand at self-elevating platform pile shoe top can destroy the adhesion between pile shoe and the earth, treats that the adhesion reduces the back, has both made things convenient for the pile pulling, helps pile shoe top earth to drop from the top naturally again. Before the pile shoe is pulled out, the high-pressure flushing water pipeline in the pile shoe is mainly used for destroying the adhesion force between the top of the pile shoe and collected sand, and the collected sand is favorably fallen from the top of the pile shoe in the pile pulling process. And the cleaning openings are arranged as many as possible under the condition that the structural strength of the pile shoe allows, so that the cleaning effect is further improved. When the pile shoe is retracted to be close to the bottom plate of the ship, the high-pressure flushing water pipeline and the flushing pipeline outside the pile shoe are opened simultaneously, and the top of the pile shoe is flushed again. The sand collection at the top of the pile shoe can be more thoroughly cleaned. Meanwhile, the top cleaning joint is designed to be inclined, so that water flow is rotated in the surrounding wall, and the cleaning effect is optimized.
