摘要
Gonghe bridge is a double level cable-stayed concrete bridge with a single-cable-plane of single cable tower. Its span is 114+120 m and a whole length of 236 m. The gliding scaffold equipment is used for the first time in the long span cable-stayed bridge construction to reduce the construction time limit. In the process of construction, to make sure a safe connection among concrete objects with different ages, the single-supporting and single-suspension system is adopted before the concrete pouring. While the double-supporting and single-suspension system is applied after con- crete pouring. These construction systems with gliding scaffold equipment are first introduced in long span ca- ble-stayed bridge and presented in detail[1]. The practice shows that these gliding scaffold systems have many advan- tages over the traditional ones.
