Innovation of hydraulic structrue in Jiahuwan Power Plant supporting wharf in Lufeng
The uneven settlement of wharf surface and the unsmooth convergence between large and small berths are common quality problems in the gravity wharf.The supporting wharf of No.1-2 generating units and No.3-4 generating units of Jiahuwan Power Plant in Lufeng,Guangdong is a shore-wall gravity wharf.Compared with the caisson components of about 2,000 t of conventional wharves,the main body of the this wharf is adopted a super-large caisson with a mass of more than 4,600 t,which reduces the number of components and structural joints.By unifying the loading conditions of the main components and setting the transition plate,the uneven settlement of the wharf surface is solved.By setting the transition caisson and the prefabricated block,the foundation compaction at the convergence between large and small berths is solved.At the same time,a series of innovations is made in the integrated design of marine structure and superstructure and the selection of ancillary facilities.The practice shows that the expected results is achieved.
