Variable fulcrum construction auxiliary beam for underneath passing existing line construction and construction method
The invention provides a variable fulcrum construction auxiliary beam for underneath pass existing line construction and a construction method. The variable fulcrum construction auxiliary beam comprises a plurality of longitudinal beams, and each longitudinal beam comprises a first top plate, a first bottom plate, two first webs, a plurality of first reinforcing ribs and a plurality of splice plates. According to the variable fulcrum construction auxiliary beam for underneath pass existing line construction and the construction method, through mutual cooperation of the longitudinal beams, the cross beams and the transverse lifting beams, when the auxiliary beam is used, the transverse lifting beams penetrate into the bottoms of steel rails, are fixed to the tops of pile columns to support the longitudinal beams, penetrate into the cross beams and are connected with the line steel rails; according to the construction auxiliary beam, the longitudinal beams are hoisted for connection, the multiple longitudinal beams are spliced and the like, the positions of fulcrums can be changed according to on-site arrangement, so that the construction auxiliary beam can be flexibly adjusted according to different geological conditions and construction requirements, the performance of the construction auxiliary beam is greatly improved, and the construction auxiliary beam is not limited by a fixed structure any more; the device can better adapt to various complex construction sites, and the application range of the device is widened.
本发明提供一种用于下穿既有线施工的可变支点施工便梁及施工方法，包括：多个纵梁，多个纵梁均包括第一顶板、第一底板、两个第一腹板、多个第一加强肋和多个拼接板。本发明提供的一种用于下穿既有线施工的可变支点施工便梁及施工方法，通过纵梁、横梁和横抬梁相互进行配合，在进行使用的时候，将横抬梁穿入钢轨底部并固定在桩柱顶部为纵梁提供支撑，穿入横梁并连接线路钢轨，吊装纵梁进行连接以及对多个纵梁进行拼接等操作，能够根据现场布置变换支点位置，这使得施工便梁可以根据不同的地质条件和施工要求进行灵活调整，极大地提高了施工便梁的性能，不再受限于固定结构，能更好地适应各种复杂的施工现场，扩大了其适用范围。
