Description

Concrete pipe pile transportation system for rising, falling and tide tidal flat photovoltaic power generation

Technical Field

The utility model relates to a water and electricity engineering construction technical field, concretely relates to rising and moving back tide mud flat photovoltaic power generation tubular pile transportation system.

Background

According to the national policy of energy conservation and emission reduction for coping with climate change and the arrangement of national adjustment on energy structures, a large number of coastal mudflat investment and construction photovoltaic power generation projects will exist in the future, by taking the long-and-long mudflat photovoltaic project in Xiangshan county of Zhejiang province as an example, the project is located in the west coastal mudflat zone of the rural yarn cap green village in Nippon county of Zhejiang province, the total installed capacity of the project is 300MWP, the main infrastructure of the project construction is to bury 10 thousands of concrete pipe piles, and a solar photovoltaic support and a daylighting panel are installed on the upper portions of the concrete pipe piles.

Concrete pipe piles are usually loaded on barges and then transported by barge to the site where they are installed. The specification of the barge is as follows: the length of the concrete pipe pile is 8m multiplied by the width of the concrete pipe pile is 3m multiplied by the height of the concrete pipe pile is 1.2m, the diameter phi of the concrete pipe pile is 300-400 mm, the length of the concrete pipe pile is 12-14 m, the wall thickness of the concrete pipe pile is about 100mm, and the weight of the concrete pipe pile is about 2.3-3.1 t.

Due to the natural law of rising and falling tide on the beach, the pipe pile can be transported by a barge during rising and falling tide. After ebb tide, the depth of the beach sludge reaches more than 10 meters, the barge is difficult to walk in the sludge, a river channel with proper depth and width is dug in the sludge to move forward by the aid of an excavating arm, and the walking speed is extremely low. The conventional construction method at present is that 6 pipe piles are conveyed each time by dragging a barge through a ship or a boat-type excavator (the barge is an unpowered pontoon) when the tide rises, and small canals which are criss-cross are dug through digging arms in a wide beach when the tide falls, so that the barge can pass in the small canals. And the method of digging a large number of ditches in the beach for barge passing is adopted during the ebb tide, so that the cost is increased due to the great increase of the construction amount, and the uneven beach surface influences the pile foundation construction.

Another transportation mode for the beach with tide rising and ebb is that a cofferdam is built along the photovoltaic construction outer boundary line of the beach, so that the water level in the cofferdam is always kept at a certain depth without being influenced by the tide rising and ebb, and the barge can float on the water surface and pass. Because the silt is deep and the rising and falling tide water level at the position 800m away from the coast of the beach usually reaches about 3m, the difficulty of constructing a long cofferdam (for example, a 7KM cofferdam needs to be constructed on the long shoal in Xiangshan county of Zhejiang province) is high under the condition, the construction period is long, and the cost is increased.

Therefore, the two methods are not available, and the main problem to be solved in the construction of the coastal beach photovoltaic power generation project is how to transport the concrete pipe pile to the installation site of the concrete pipe pile on the beach without changing the existing beach condition, rising and falling tide, high efficiency and low cost.
