Sightseeing and TV Tower in Macau, China

摘要

Located on the first section of the Nanwan reclamation region D of the Macau Peninsula, Macau Tower is 348m high (including a 9om-high transmission mast) and is the fourth highest concrete tower in China. The main body of the tower is cylindrical, with a diameter of 12m at the top and 16m at the bottom, with corresponding wall thicknesses of 350mm and 500mm. It was constructed using jumpform. At 248m, there is a 1.3m-thick concrete transfer slab to support the 90m steel mast. The body of Macau Tower is supported by eight inclined reinforced-concrete legs, constructed using precast concrete members as permanent formwork. Four precast units 4m long are joined to form a 2.7 × 1.7m rectangular section. Precast forms were selected to minimise the finishing work and to avoid affecting the appearance of the legs. The foundation raft slab forthe legs was connected to that of the tower.
