Description
Technical field
The invention belongs to the long-distance overlapping shield tunnel of small clear distance technical field of construction, especially relate to a kind of long-distance overlapping shield tunnel of small clear distance and use movable wheel type trolley supporting system.
Background technology
From the engineering practice of home and abroad, the case history of long-distance overlapping shield tunnel of small clear distance is few, and is mainly Parallel Tunnel or the overlapping cross tunnel engineering of short range low-angle.During the overlapping shield tunnel construction, because first built tunnel structure receives the influence of back row shield-tunneling construction, the tunnel structure in advance in the first the place ahead of shield can bear the bigger pressure influence of back row shield tunnel construction during the row tunneling shield construction of back, thereby can produce the song of disturbing to a certain degree; And can be because the off-load influence of back row tunneling shield through producing at distortion in the tunnel in advance at shield tail rear.Therefore influence each other for what overlapping tunnel was constructed, be necessary carrying out bracing reinforcement in the tunnel in advance, to reduce the adverse effect that back row constructing tunnel produces.
At present; For parallel shield tunnel or the overlapping cross tunnel engineering of short range low-angle; In the time of the construction of back row tunneling shield, in advance or the support system in the tunnel that has built up mainly be to take the cross bracing system, the thought of this support system mainly is to support with steel the tunnel of going ahead of the rest is reinforced; Help the section of jurisdiction to bear exterior pressure, with the distortion and the slip of control section of jurisdiction.Above-mentioned cross bracing system is mainly supported by steel loop, cross steel and 4 vertical I-beam sections are formed.Steel loop and cross steel support and are positioned at circumferential weld place, section of jurisdiction; Vertically steel support respectively 16 o'clock in the tunnel, 4 o'clock, 8 o'clock and 12 o'clock the position vertically arrange along the tunnel; All adopt bolted connection between steel loop, cross bracing and the vertical I-beam section, form the integrated support system.
In the actual use; The advantage of cross bracing system is simple in structure and definite functions; The thought of this support system mainly is to support with steel the tunnel of going ahead of the rest is reinforced, and helps the section of jurisdiction to bear exterior pressure, the distortion and the slip of control section of jurisdiction; But support for the little spacing overlapping shield tunnel of long distance, the installation of cross bracing system and the work of having bad luck are very difficult.To sum up, in the little spacing overlapping shield tunnel work progress of long distance, supporting uninterruptedly in the tunnel of how realizing going ahead of the rest is the key to the issue place.At present for the little spacing overlapping shield tunnel of long distance; Because row constructing tunnel in back produces the influence through the back off-load of bigger pressure and shield structure to section of jurisdiction in the first tunnel; Tunnel structure internal force can produce jumping phenomenon in advance; Therefore be necessary carrying out bracing reinforcement in the tunnel, and along with the continuous construction of back row tunneling shield, in tunnel in advance, realizing supporting uninterruptedly is the key of problem place in advance.
