Construction method for constructing concrete box girder section of cable-stayed bridge by adopting cable-stayed hanging basket
The invention discloses a construction method for constructing a cable-stayed bridge concrete box girder segment through a cable-stayed hanging basket, and relates to the field of cable-stayed bridge concrete box girder segment construction.The construction method comprises the following steps that S1, a hanging basket lifting truss is installed, and the cable-stayed hanging basket is lifted to the designed elevation through the hanging basket lifting truss; s2, a temporary connecting steel beam is installed on a middle cross beam of the main tower, and the guy cable hanging basket is connected with the temporary connecting steel beam; s3, mounting a hanging basket stay cable and tensioning the hanging basket stay cable to a design value; s4, the hanging basket lifting truss is dismantled, and concrete box girder segments are constructed through the guyed hanging basket; s5, mounting a box girder stay cable and tensioning the box girder stay cable to a design value; and S6, the cable-stayed hanging basket is connected to the concrete box girder, the temporary connecting steel girder is dismantled, the stay cable of the box girder is adjusted to the design value, and the next concrete box girder section is constructed on the cable-stayed hanging basket. The construction method has the effects of reducing construction risks, saving construction cost and accelerating construction progress.
本申请公开了一种采用牵索挂篮施工斜拉桥混凝土箱梁节段的施工方法，涉及斜拉桥混凝土箱梁节段施工领域，其包括以下步骤：S1、安装挂篮提升桁架，通过挂篮提升桁架提升牵索挂篮至设计标高；S2、于主塔的中横梁上安装临时连接钢梁，将牵索挂篮与临时连接钢梁连接；S3、安装挂篮斜拉索并张拉到设计值；S4、拆除挂篮提升桁架，利用牵索挂篮施工混凝土箱梁节段；S5、安装箱梁斜拉索并张拉至设计值；S6、将牵索挂篮连接于混凝土箱梁，拆除临时连接钢梁，调整箱梁斜拉索至设计值，于牵索挂篮施工下一混凝土箱梁节段。本申请具有减少施工风险、节约施工成本、加快施工进度的效果。
