Abstract

The invention belongs to the technical field of shield tunnel waterproofing, and particularly relates to a shield tunnel sealing gasket waterproof performance testing device which comprises a fixing unit and a pressurizing unit. The fixing unit comprises an arc-shaped block and a control mechanism, an arc-shaped through groove is formed in the arc-shaped block, and a first arc-shaped strip is slidably connected into one side of the arc-shaped through groove; a second arc-shaped strip is slidably connected into the other side; a first arc-shaped clamping block is arranged on the first arc-shaped strip, and a second arc-shaped clamping block is arranged on the second arc-shaped strip; the control mechanism is used for controlling the pressure intensity in the arc-shaped through groove; the pressurizing unit comprises a water injection mechanism and a fixing block, and the fixing block can be attached to the first arc-shaped clamping block and the second arc-shaped clamping block in a sealed mode. A cavity is formed in the fixing block and can be opposite to the joint of the first arc-shaped clamping block and the second arc-shaped clamping block. By using the scheme, the environment of the sealing gasket can be well simulated, and the accuracy of a test result is effectively improved.

Description

Technical field[0001]The present invention belongs to the field of waterproofing technology of the shield tunnel, and in particular to a waterproof performance test device for shield tunnel sealing pads.Background technique[0002]The shield method is a full mechanical construction method in the construction of the mushroom, which is to advance the shield mechanical in the plane, and support the four-week surrounding rock to prevent the collapse of the tunnel through the shield housing and tube sheets. Digging, the cutting device is used for soil excavation. Outside the hole through unearthed mechanical, it is pressurized by jack in the back, and assembles the prefabricated concrete pipe film to form a mechanized construction method of tunnel structure. The tube seam is the weak link of the shield tunnel, facing complex geological and hydrological environments, continuously changed from the construction period to the operation period tunnel load, the seam is in a complex deformed stat...
