Small-radius curve rigid frame support cast-in-place beam rotation closure construction method
The invention belongs to the technical field related to bridge construction, and discloses a small-radius curve rigid frame support cast-in-place beam swivel closure construction method. The construction method comprises the working procedures of main pier pile foundation construction, upper and lower bearing platform construction, main pier body construction, beam body construction, first-time dismantling of a bottom die and a support, bridge deck system and auxiliary construction, second-time dismantling of the bottom die and the support, weighing and counterweight construction, swivel construction, turntable locking, beam end support installation, padstone pouring, turntable pouring and the like. Through the method, multiple technical problems in swivel construction in the prior art can be better solved under the condition that no closure section exists, and meanwhile the method has the advantages of being convenient to operate and control, high in reliability and construction efficiency, high in environmental adaptability and the like, and is particularly suitable for building construction of small-radius single-track railway rigid frame bridges.
本发明属于桥梁施工相关技术领域，并公开了一种小半径曲线刚构支架现浇梁转体合龙施工方法，其包括主墩桩基施工、上下承台施工、主墩墩身施工、梁体施工、底模和支架的第一次拆除、桥面系及附属施工、底模和支架的第二次拆除、称重和配重施工、转体施工、转盘锁定、梁端支座安装及垫石浇筑，以及转盘浇筑等工序。通过本发明，能够在无合龙段的情况下更好地解决现有技术转体施工中的多个技术问题，同时具备便于操控、可靠性和施工效率高、环境适应性强等优点，并尤其适用于小半径单线铁路刚构桥梁的建筑施工用途。
