The invention provides a double-slideway prestressed concrete beam pushing system and a construction technology, and belongs to the technical field of large-span gate-type pier construction.The double-slideway prestressed concrete beam pushing system comprises a concrete cap beam prefabricated section support arranged on the outer side of a concrete pier column and a pushing support arranged on the inner side of the concrete pier column; slide way beams are arranged on the two sides between the cap beam prefabricated section support and the pushing support, gate-type pier cap beam prefabricated section concrete is poured at the top end of the cap beam prefabricated section support, and embedded brackets are arranged on the two sides of the gate-type pier cap beam prefabricated section concrete. The extending section of the embedded bracket is lapped on the upper surface of the slideway beam and is supported by the slideway beam, and an MGE sliding plate is arranged on the lower surface of the embedded bracket; a self-walking pushing mechanism is arranged between one end, far away from the pushing bracket, of the gate-type pier cap beam prefabricated section concrete and the slideway beam; interference on the existing railway can be reduced, operation and safety of the existing railway under the bridge are guaranteed, and work efficiency is improved while operation safety is improved.
本发明提供一种双滑道预应力混凝土梁顶推系统及施工工艺，属于大跨径门式墩施工技术领域，包括设于混凝土墩柱外侧的混凝土帽梁预制段支架以及设于混凝土墩柱内侧的顶推支架，所述帽梁预制段支架与顶推支架之间的两侧均设有滑道梁，所述帽梁预制段支架的顶端浇注有门式墩帽梁预制段混凝土，所述门式墩帽梁预制段混凝土的两侧均设有预埋牛腿，所述预埋牛腿的伸出段搭于滑道梁的上表面且通过滑道梁支撑，所述预埋牛腿的下表面设有MGE滑板；所述门式墩帽梁预制段混凝土远离顶推支架的一端与滑道梁之间设有自行走顶推机构；本发明可以减少对既有铁路的干扰，保证了桥下既有铁路的运营与安全，提高作业安全性的同时提高工效。
