Railway box girder tunnel portal erecting method
The invention provides a railway box girder tunnel portal erecting method. A girder transporting vehicle and a carrying support are used in the erecting method. The erecting method comprises the steps that S1, the girder transporting vehicle transports the bridge girder erection machine to advance until the middle supporting leg extends out of the beam bearing stone of the tunnel portal bridge abutment; s2, the vertical state of the middle supporting leg and the machine arm is recovered, the bridge girder erection machine is consigned to move back to the position, located on the front side of the bridge abutment, of the middle supporting leg through the girder transporting vehicle, and supporting is conducted through the supporting leg; s3, the height of the vehicle arm is increased, and then the middle supporting leg is shrunk and suspended; s4, the rear supporting leg drives the machine arm to advance, the middle supporting leg moves relative to the machine arm, and the middle supporting leg is supported in place; s5, the front supporting leg arrives at the position of the next bridge pier and supports the next bridge pier, the rear supporting leg is turned over and lifted, and the girder transporting vehicle exits from the bridge erecting machine; s6, the girder transporting vehicle feeds the girders in place at a time, and the rear supporting legs are folded in place for supporting; the crane carriage travels to a beam taking position and takes a beam at the same time; the front crane carriage and the rear crane carriage synchronously transport the beam, the beam falls in place, and the beam transport vehicle exits. According to the erecting method, the tunnel portal beam erecting efficiency is greatly improved.
本发明提供一种铁路箱梁隧道口架设方法，架设方法使用到运梁车及驮运支架；架设方法包括：步骤S1，运梁车托运架桥机前进至中支腿伸出隧道口桥台的垫梁石；步骤S2，恢复中支腿与机臂垂直状态，并使用运梁车托运架桥机后退至中支腿位于桥台的前侧位置，支腿支撑；步骤S3，机臂高度提升，然后中支腿收缩悬空；步骤S4，后支腿驱动机臂前进，中支腿相对机臂移动，中支腿到位支撑；步骤S5，前支腿到下一个桥墩位置并进行支撑，后支腿翻折抬起，运梁车退出架桥机；步骤S6，运梁车一次喂梁到位，后支腿翻折到位支撑；起重小车行驶至取梁位，同时取梁；前、后起重小车同步运梁，落梁到位，运梁车退出。该架设方法极大提高了隧道口架梁效率。
