芦溪大桥全长100.42米,四孔跨径20米T型砼梁桥,中梁重21.6,边梁重20.5。我队1985年修建时,采用简易方法吊装20米砼T型梁桥,既简便,又安全,节省经费。现简述如下。一、吊装方法及步骤 1.场地横移预制T梁强度达到设计要求后,在两端1~#至2~#隔板内的梁板下每端放两根钢轨,用道木垫平,穿好梁的捆绑索,用φ20高6米的三脚扒杆立于梁的两端,采用两个10手动葫芦同时起动,当起动到能将活动支架放下为止,并将活动支架的螺丝拧紧,在钢轨的表面加少最润滑油,用其支架与
Luxi Bridge, a full-length 100.42 meters, four-hole span 20 meters T-type concrete beam bridge, beam weight 21.6, side beam weight 20.5. When my team built in 1985, using a simple method of lifting 20-meter concrete T-beam bridge, both simple, safe, cost-saving. Are summarized below. First, the hoisting method and steps 1. Field prefabricated T-beam strength to meet the design requirements, at both ends of 1 ~ # to 2 ~ # partition board placed two beams under each end of each rail, Put on the beam bundle cable, with φ20 high 6 meters of the three-legged grill rod stand on both ends of the beam, using two 10-hand hoist start at the same time, when activated to the activities of the stent down so far, In the rail surface to add the least oil, with its support and
