River-crossing cableway bridge construction method
The invention provides a river-crossing cableway bridge construction method which comprises the following steps that S1, a cable tower is manufactured, the cable tower is of a double-limb portal frame type structure, a concrete bearing platform is independently arranged behind work to serve as a cable tower foundation, and each limb column is a latticed column formed by combining a plurality of steel pipes through horizontal and oblique lacing bars made of I-steel, the cable bent tower is vertically divided into a plurality of cable bent tower sections, and the plurality of cable bent tower sections are hoisted by a truck crane; s2, after hoisting is completed, the two adjacent cable bent tower sections are in field bolt connection through flange plates; and S3, cable cranes are installed on the cast cable towers on the two banks, and at least two sets of cable cranes are arranged. According to the method, the cable bent tower components are assembled into the standard knot on site and then are integrally hoisted by adopting the truck crane, so that the control on the line shape is ensured, the influence on the main body line shape is reduced, the construction difficulty is reduced, and meanwhile, the construction efficiency is also ensured.
本发明提供一种过江索道桥施工方法，包括以下步骤：步骤S1，制作缆塔，缆塔为双肢门架式结构，在工作后方单独设置混凝土承台作为缆塔基础，每个分肢柱为数个钢管通过工钢制成的水平和斜向缀条组合形成的格构柱，布置为竖向分为数个索塔节段，数个所述索塔节段采用汽车吊吊装；步骤S2，吊装完成后，相邻的两索塔节段之间采用法兰板现场螺栓连接；步骤S3，在已浇筑完成的两岸缆塔上安装缆索吊，所述缆索吊至少设有两组。本发明通过将索塔构件在现场组拼成标准节后，采用汽车吊整体吊装，保证对线形的控制，降低对主体线性的影响，降低施工难度，同时也保证了施工效率。
