Since the tunnel is a building built underground, underwater or in the mountain for motor vehicles, the second lining of the tunnel is An important part of the tunnel support system, the secondary lining is the final safety barrier, which can not only bear the stress load of the surrounding rock deformation together with the primary support, but also serve as the last barrier to ensure construction and operation safety. The construction of the second lining of the tunnel is often designed as two parts, the inverted arch and the arch wall. In order to meet the waterproof requirements of the construction joints of the inverted arch and the arch wall, a longitudinal steel edge waterstop is installed at the construction joints of the inverted arch and the arch wall. However, the traditional longitudinal There is no positioning device to fix its spatial position during the construction of the steel edge waterstop, resulting in changes in the spatial position of the longitudinal steel edge waterstop after the concrete is poured, and the straightness of the steel edge waterstop is uncontrollable. The installation of the existing manual longitudinal steel edge waterstop is highly arbitrary, and it is difficult to maintain the consistency and accuracy of the spatial position of the waterstop, which will cause the longitudinal steel edge waterstop to be not straight after the construction of the second lining concrete, which will affect the second lining. Waterproof performance, endangering the personal safety of traffic vehicles and passengers.
