It is suitable for the tunnel structure in the urban subway cross-line rail transit. During the construction of the cross-tunnel, due to the mechanical construction, the surrounding rock of the tunnel will be shaken. Since the tunnel is an upper and lower tunnel, the shaking of the surrounding rock will cause interaction forces. , causing another tunnel to shake, affecting the safety of the tunnel

The invention discloses an up-down cross tunnel damping structure which comprises a first tunnel, wherein a second tunnel is arranged on the top of the first tunnel; damping columns are arranged inside the lower layer of the second tunnel; the top of each damping column is fixedly connected with the bottom of a pressure reducing plate; the bottom of each damping column is fixedly connected with the top of an interlayer; the bottom of the pressure reducing plate is fixedly connected with a damping device; the damping device comprises a first fixing block; and the top of the first fixing block is fixedly connected to the bottom of the pressure reducing plate. According to the up-down cross tunnel damping structure, due to the first fixing block, the pressure reducing plate, a pressure reducing rod and an extrusion plate, vibration is effectively alleviated when the tunnel is mechanically constructed, the condition that a tunnel crossed with the previous tunnel shakes due to shake is avoided, and the safety of the tunnel is improved. According to the extrusion plate, a pressure reducing spring and a fixing plate, vibration can be well reduced during tunnel construction, and the tunnel is prevented from shaking.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a vibration-absorbing structure for an upper and lower intersection tunnel. Background technique [0002] Cross tunnel is a special form of tunnel structure in which two tunnel structures cross each other at a certain angle. It is suitable for the tunnel structure in the urban subway cross-line rail transit. During the construction process of the cross tunnel, due to the mechanical construction, the surrounding rock of the tunnel will be shaken. Since the tunnel is an upper and lower tunnel, the shaking of the surrounding rock will cause interaction forces. , causing another tunnel to shake, affecting the safety of the tunnel. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides an up and down crossing tunnel damping structure, which solves the situation that the surro...
