Grade crossing method and structure of diversion tunnel and grouting tunnel
The invention discloses a grade crossing structure of a diversion tunnel and a grouting tunnel. The grade crossing structure comprises an upper layer grouting tunnel, a lower layer grouting tunnel, the diversion tunnel and a traffic tunnel. An underpass section located below the diversion tunnel is arranged in the lower layer grouting tunnel. The traffic tunnel penetrates through the diversion tunnel, and the two ends of the traffic tunnel communicate with the two ends of the underpass section correspondingly. The portion, located in the diversion tunnel, of the traffic tunnel is a traffic corridor. The upper layer grouting tunnel is located above the diversion tunnel. The elevation of the lower layer grouting tunnel is the same as the elevation of the diversion tunnel. By means of a gradecrossing method and the grade crossing structure of the diversion tunnel and the grouting tunnel, the construction progress during grade crossing of the diversion tunnel and the grouting tunnel is accelerated, and the construction period of diversion tunnel blockage is shortened.
本发明公开了一种导流洞与灌浆洞的平面交叉结构，包括上层灌浆洞、下层灌浆洞、导流洞和交通洞，所述下层灌浆洞中设置有位于所述导流洞下方的下穿段，所述交通洞穿过所述导流洞且所述交通洞的两端分别与所述下穿段的两端连通，所述交通洞位于所述导流洞中的部分为交通廊道；所述上层灌浆洞位于所述导流洞的上方，所述下层灌浆洞的高程与所述导流洞的高程相同。本发明导流洞与灌浆洞的平面交叉方法及结构提高了导流洞与灌浆洞的平面交叉时的施工进度，减少导流洞封堵的工期。
