Construction method for continuous beam of extra-large bridge turnout of elevated station
The invention discloses a construction method for a continuous beam of an extra-large bridge turnout of an elevated station. The construction method comprises the following steps that S1, pier construction, wherein pile foundation construction, steel sheet pile construction, bearing platform construction and pier body construction are conducted in sequence to form piers; S2, a middle section bridge is constructed; S3, two end section beams located on the two sides of the middle section bridge are synchronously constructed, specifically, step S21 to step S24 are repeated to make the middle section bridge and the two end section beams form a continuous beam, wherein the beam section reinforcing steel bars corresponding to the middle section bridge and the beam section reinforcing steel bars corresponding to the end section beams are bound and connected to form binding section reinforcing steel bars, and the binding section reinforcing steel bars are located between the two bridge piers; and S4, the continuous beam is tensioned. The method is suitable for variable terrains, convenient to construct and high in engineering quality.
本发明公开了一种高架站特大桥道岔连续梁施工方法，包括步骤：S1，桥墩施工：依次进行桩基施工、钢板桩施工、承台施工和墩身施工以形成桥墩；S2，中间节段桥梁施工；S3，位于所述中间节段桥梁两侧的两个端节段梁同步施工：重复步骤S21至步骤S24，使得所述中间节段桥梁、两个所述端节段梁形成连续梁；其中，中间节段桥梁对应的梁段钢筋与所述端节段梁对应的梁段钢筋因张拉压浆而预留空间的钢筋绑扎连接以形成绑扎段钢筋，所述绑扎段钢筋位于两个所述桥墩之间；S4，张拉所述连续梁。本发明适用多变地形、施工便捷且工程质量高。
