this is the entrance of the tunnel, the road to go out, don't cross the street or on the set, the vehicle collision buffer material (11) on a concrete or metal material, and a supporting rod (12) to the team is set up, the team bracket (12) uc55euc5d0 buffer role. porous medium the hole (15) in the form of a metal material of concrete or synthetic resin to coat the film (14) of the tongue (11) is formed as a buffer material to the conflict, and the buffer to buffer material (11) is one of the porous space (15) to it is of oval or circular. tile shape, polygon shape, composed with a variety of spatial form,the rapid relaxation of the shock absorption degree, in order to control the power of the concrete in the space (15) to create a rapid hit buffer role, mainly, in order to maintain a strong, even outside the group stand (12) of the concrete. a reinforcing bar (20), and a metal insert in the away team bracket (12) attached to the ground, the city's rapid collision left bracket (12) by the group of the structure damage degree greatly drop will be a disaster, and casualties, and at the same time. minimization can be installed in the city, the beautiful can improve the hole (15), in the form of concrete impact buffer material (11) to be set up as an accident, and the lives and safety of the structure can ensure the structure.
