一、前言目前对于高桥的鋼筋混凝土梁及予应力鋼筋混凝土梁的检查检定工作,尚沒有一种完善地拼装活动式检查設备。因桥梁各部結构复杂,附属設备又多,設計一种适用于各种桥梁的多能检查架是比較困难的。我局根据鉄路专业設計院設計的“拼装式(活动)多能检查設备”(专桥8111)图紙,委托西北鉄路工程局修配厂制造了一套。由于在复綫桥梁中,中間吊杆安装困难,扒碴費工,經西安工务段研究取消了吊杆,改进了結构形式,經多次試驗使用,效果很好,滿足了检查工作需要。
I. Preface At present, there is no perfect check-up equipment for the inspection and verification of reinforced concrete beams and prestressed reinforced concrete beams in Takahashi. Due to the complex structure of the bridges and the large number of ancillary equipment, it is difficult to design a multi-purpose inspection frame suitable for various bridges. According to the drawings of the “Assembled (Activities) Multi-functional Inspection Equipment” (Zhuqiao 8111) designed by Kushiro Professional Design Institute, I Bureau commissioned a set of repairing plants of the Northwest Kushiro Engineering Bureau. As in the double-track bridge, the middle of the boom installation difficulties, scraping ballast work, the Xi’an section of the lifting of the lifting of the boom, improved structure, the use of multiple tests, the effect is very good, to meet the inspection needs.
