Sealing guide joint for expansion joint and leakage induction for tunnel retaining wall

摘要

In particular, in the construction of retaining wall construction such as tunnels, the reinforcement of tunnel structures can be economically and efficiently prevented from leaking external rainwater to the interior through seams formed during construction in consideration of thermal deformation of concrete. It is provided to implement, the configuration includes an elasticity capable of maintaining the shape of an artificial bend, the rubber support is provided in the form of a tube while forming a recess groove in the front and rear along the longitudinal direction; A reinforcing iron core which is insulated along its longitudinal direction within a thickness forming an outer circumferential surface of the rubber support; An insulating material tightly filled in the tube; Water absorbing induction material of the round rod-shaped in close contact with the indentation groove in the rear; And fastening pieces are fixed to both sides of the front surface of the rubber support so that the bolt can be fastened with the retaining wall.
