Description

Technical Field

[0001] The invention relates to a tidal flat photovoltaic construction platform and a construction method thereof, belonging to the technical field of new energy power generation facilities. Background Art

[0002] As the construction of new energy sources in China accelerates, all sites that can be used for new energy construction are being utilized. The previously abandoned coastal mudflats are gradually being utilized, one of which is the construction of photovoltaic power plants. Photovoltaic power plants generally involve driving thousands of PHC piles in the field, installing steel structure photovoltaic brackets on the top of the piles, and laying photovoltaic panels on the brackets. At high tide, the PHC piles are partially submerged by seawater, and at low tide, the seabed is exposed. Taking a 200MW mudflat photovoltaic power plant as an example, it is necessary to construct nearly 60,000 PHC piles, more than 11,000 tons of photovoltaic steel brackets, and install nearly 450,000 photovoltaic panels. The construction period is generally required to be about 1 year.

[0003] Such a large-scale project requires huge human and material resources. During peak periods, there are thousands of construction workers. In addition, the tidal flat area is affected by the rise and fall of tides. Sometimes there is water and sometimes there is no water. It is inconvenient for personnel and equipment to enter and exit the area, and they need to take advantage of the tide. The installation of photovoltaic brackets and photovoltaic panels in this tidal flat area usually uses buoys and other temporary floating construction platforms. Personnel stand on the platform to carry out superstructure construction. However, this method is easily affected by the rise and fall of tides and cannot be constructed 24 hours a day. It is easily affected by water flow and waves. The platform shakes significantly with the waves. People standing on a temporary platform at a height of about 6m are very likely to panic, which has many safety hazards and low construction efficiency. Therefore, we propose a tidal flat photovoltaic construction platform and its construction method. Summary of the invention
