Description
Technical Field
The invention relates to a tunnel boring machine, in particular to a tunnel boring machine with a waterproof film laying bin section and a tunnel construction method.
Background
The tunnel engineering is under the ground and faces higher waterproof test, and the general requirement reaches the requirement of secondary waterproof. For important tunnel engineering, such as high-speed railway tunnels and underwater tunnels, the primary waterproof requirement is required to be met, namely dripping water is not leaked.
With the rapid development of economic technology and the continuous improvement of urban environment protection requirements, the open cut method of urban tunnels has been gradually abandoned due to the defects of traffic blockage, high dust pollution and the like, and the construction methods such as shield, TBM, jacking pipe and the like are becoming the main flow construction method of urban tunnel construction more and more.
The construction of the tunnel boring machine inevitably stops, so that various joints exist in the tunnel lining, such as joints among shield tunnel segments, longitudinal joints, construction joints of TBM tunnel loops, construction joints of arch walls and inverted arch interfaces and the like. Meanwhile, a settlement joint is also arranged along the longitudinal direction of the tunnel in a manual mode. The existence of the seam weakens the waterproof capability of the tunnel and is a serious difficulty in waterproof of the tunnel of the existing heading machine.
The tunnel waterproofing is quite different according to the types of the heading machines. If the shield tunnel is mainly provided with a duct piece self-waterproof function, a sealing gasket is used for waterproof at the joint position, and a waterproof and drainage plate is arranged between the primary lining and the secondary lining of the TBM tunnel.
From the aspect of tunnel operation practice, the existing waterproof measures of the tunnel cannot meet the higher waterproof requirement of tunnel engineering. If the shield tunnel construction duct piece has the defect of dislocation, the waterproof effect of the joint sealing gasket is weakened. The TBM tunnel waterproof board laying technical requirement is higher, and the defects that an anchor rod punctures the waterproof board, the lap joint position of the waterproof board is not tight in sealing and the like often occur, and after the tunnel is operated for a long time, water leakage can occur, so that the normal operation of the tunnel is seriously influenced.
