Tunnel and anchor integrated suspension bridge anchor structure and construction method thereof
The invention discloses a tunnel and anchor integrated suspension bridge anchor structure and a construction method thereof. The tunnel and anchor integrated suspension bridge anchor structure comprises an anchor body wrapping a main line tunnel, and the anchor body and the main line tunnel form an integrated structure. The existing or newly-arranged main line tunnel is subjected to expanding excavation and anchor body pouring is performed, the anchor body and the main line tunnel form a whole, the measure that if surrounding rock mass around a tunnel anchor is poor, the anchor ingot depth needs to be too large is avoided, and the problem that the anchor body and the main line tunnel form a small clear distance structurally is solved. In addition, the anchor body and the main line tunnel form a whole, and the anchor body is equivalent to a gravity type anchor block and is not limited by topographic conditions. The advantages of the gravity type anchor and the tunnel anchor are combined, the influence of factors such as surrounding rock conditions and whether a main line tunnel exists or not does not need to be considered, and the use range of a suspension bridge is widened.
本发明公开一种隧锚一体的悬索桥锚锭结构及其施工方法，包括包裹主线隧道的锚体，所述锚体与主线隧道形成一个整体结构；本发明通过对既有或新设主线隧道进行扩挖，浇筑锚体，是锚体与主线隧道形成一个整体，避免了若隧道锚周围围岩岩体较差，则需要锚锭深度过大的措施，还避免了与主线隧道形成结构上的小净距问题。除此之外，锚体与主线隧道形成一个整体，锚体相当于重力式锚块，不受限于地形条件；本发明结合了重力式锚锭和隧道锚各自的优点，不用考虑围岩条件、是否有主线隧道等因素的影响，提高了悬索桥的使用范围。
