Construction method of box-type bridge without bent cap
The construction method comprises the following steps that S1, multiple sets of box girder assemblies are prefabricated, each box girder assembly comprises a box girder body and two end cross beams, and a through hole is formed in each end cross beam; s2, a temporary support is built, the multiple sets of box girder assemblies are sequentially hoisted and erected on the temporary support, and a plurality of communicated through holes jointly form a steel beam channel; s3, a transverse steel beam is prepared, the transverse steel beam is arranged in the steel beam channel in a penetrating mode, and after the transverse steel beam is tensioned, the two ends of the transverse steel beam are anchored to the two end cross beams on the outermost side; and S4, the multiple sets of box girder assemblies synchronously fall on the piers. According to the box-type bridge construction method, a bent cap structure in the prior art does not need to be arranged, so that the attractiveness of the bridge can be improved, in addition, the site construction difficulty is reduced through assembly type construction, the site construction period can be shortened, and the safety in the site construction process can be improved.
本发明公开了一种无盖梁的箱式桥梁施工方法，包括以下步骤：步骤S1，预制多组箱梁组件，箱梁组件包括箱梁本体以及两个端横梁，每个端横梁内部均具有通孔；步骤S2，搭建临时支架，将多组箱梁组件依次吊起并搭设于临时支架上，相连通的多个通孔共同形成钢束通道；步骤S3，准备横向钢束，将横向钢束穿设于钢束通道内，张拉横向钢束后将横向钢束的两端锚固于最外侧的两个端横梁之上；步骤S4，使得多组箱梁组件同步落在桥墩之上。本发明中的箱式桥梁施工方法无需设置现有技术中的盖梁结构，因此可提高桥梁美观性，此外，通过装配式施工降低了现场施工难度，并可缩短现场施工周期、提高现场施工过程中的安全性。
