Construction method for assembling prefabricated anchorage open caisson through cable crane
The invention provides a construction method for assembling a prefabricated anchorage open caisson by using a cable crane, which comprises the following steps of: firstly constructing approach bridge piers and a cover beam of a suspension bridge, then using two approach bridge piers on two sides of an anchorage design position of the suspension bridge as cable sling towers, and using the cover beam on the piers as a cable bent tower cross beam to mount a cable rotating saddle; a bridge pier bearing platform on the outer side of a bridge pier serving as a cable bent tower is used for arranging a cable crane anchoring system, a cable crane system crossing a suspension bridge anchorage is erected, cable cranes are used for assembling anchorage open caisson prefabricated blocks, ground traction equipment is matched with the cable cranes, the transverse coverage range of the cable cranes is expanded through a swing shifting method, and prefabricated anchorage open caisson construction is completed. According to the method, a cable sling tower and an anchorage do not need to be independently arranged, so that the cable hoisting method is applied to the fabricated anchorage open caisson construction at low cost, and the popularization and popularization of the prefabricated fabricated technology in the anchorage open caisson construction are facilitated.
本发明提供一种用缆索吊拼装预制锚碇沉井的施工方法，首先施工完成悬索桥的引桥桥墩及盖梁，然后利用悬索桥锚碇设计位置两侧的两引桥墩作为缆索吊索塔，利用桥墩上的盖梁作为索塔横梁安装转索鞍，利用作为索塔的桥墩外侧的桥墩承台设置缆索吊锚固体系，搭设跨越悬索桥锚碇的缆索吊系统，利用缆索吊拼装锚碇沉井预制块，并采用地面牵引设备配合缆索吊通过荡移法扩大缆索吊的横向覆盖范围，完成预制锚碇沉井施工。本发明不需要单独设立缆索吊索塔和锚碇，从而以较低成本将缆索吊法应用到装配式锚碇沉井施工中，有利于促进预制装配式技术在锚碇沉井施工中推广普及。
