Door-shaped foundation D-shaped auxiliary beam overhead system and construction method
The invention provides a portal foundation D-shaped auxiliary beam overhead system and a construction method, and belongs to the technical field of railway engineering. The door-shaped foundation structures are sequentially arranged in the length direction of an existing line, the D-shaped auxiliary beam structures are arranged on the door-shaped foundation structures, the existing line is arranged on the D-shaped auxiliary beam structures, and each door-shaped foundation structure comprises two pile foundations arranged on the two sides of a newly-built tunnel respectively and a transverse straining beam connected between the two pile foundations; the transverse straining beam extends in the width direction of the existing line, a buttress is arranged on the transverse straining beam, and the D-shaped auxiliary beam structure is arranged on the buttress. A door-shaped foundation structure is implemented below the existing line in advance, and a D-shaped auxiliary beam structure is arranged on a buttress on a cross tie beam, so that the problem that the existing line is difficult to reinforce and protect in the project that a large-section tunnel downwards passes through the existing line at a small angle is solved; same-span arrangement of the longitudinal beams on the left side and the right side of the D-shaped auxiliary beam structure can be achieved, the triangular pit problem caused by staggered arrangement of the longitudinal beams is avoided, and operation safety of an existing line is guaranteed.
本发明提供一种门型基础D型便梁架空体系及施工方法，属于铁路工程技术领域。它包括若干沿既有线路长度方向依次设置的门型基础结构和设于门型基础结构上的D型便梁结构，既有线路设置在D型便梁结构上，门型基础结构包括两个分别设于新建隧道两侧的桩基础和连接在两桩基础之间的横系梁，横系梁沿既有线路的宽度方向延伸，横系梁上设有支墩，D型便梁结构设置在支墩上。通过在既有线路下方预先实施门型基础结构，将D型便梁结构置于横系梁上的支墩上，从而解决了大断面隧道小角度下穿既有线路工程中既有线路加固防护困难的问题；可以实现D型便梁结构左右两侧纵梁的同跨布置，避免了纵梁错位布置所引起的三角坑问题，保证既有线路的运营安全。
