Bridge first span precast beam boundary beam of tunnel connection bridge and erecting method of bridge first span precast beam boundary beam
The invention discloses a tunnel connection bridge first span precast beam boundary beam and an erecting method thereof.The tunnel connection bridge first span precast beam boundary beam comprises a cover beam body and a transverse displacement device, check blocks are arranged on the two sides of the top end of the cover beam body, a plurality of sets of padstones are arranged at the top end of the cover beam body, and the transverse displacement device is arranged on the cover beam body; a plastic film is flatly laid at the top end of the capping beam body and located on the sides, close to a tunnel portal, of the padstones, a concrete leveling layer is poured on the plastic film, an embedded PVC pipe is arranged in the capping beam body and located between every two adjacent padstones, a steel bar penetrates through the interior of each embedded PVC pipe, and the steel bar is connected with the steel bar. According to the tunnel connection bridge first span precast beam boundary beam and the erecting method thereof, by means of the center hole jack, the sliding steel plate, the steel strand and the joist manganese steel plate, a T beam can be easily pushed to the position close to the stop block from the middle position of the cover beam body, and the problem that during bridge and tunnel connection construction, the T beam is not prone to falling off is solved. And when the first span edge beam is erected, the bridge girder erection machine cannot transversely move to a preset position.
本发明公开了一种隧接桥桥梁首跨预制梁边梁及其架设方法，包括盖梁本体和横向位移装置，所述盖梁本体顶端的两侧均设有挡块，所述盖梁本体的顶端设置有垫石，所述垫石设置有多组，所述盖梁本体的顶端且位于垫石靠近隧道洞口的一侧平铺有塑料膜，所述塑料膜上浇筑有混凝土调平层，所述盖梁本体的内部设有预埋PVC管，所述预埋PVC管位于相邻两个垫石之间，所述预埋PVC管的内部贯穿有钢棒，本发明隧接桥桥梁首跨预制梁边梁及其架设方法，通过借助穿心千斤顶、滑行钢板、钢绞线和托梁锰钢板，可以轻松将T梁从盖梁本体中间位置推移到靠近挡块的位置，解决了桥隧相连施工时，架设首跨边梁时架桥机无法横移至预定位置的问题。
