Abstract

The invention discloses a waterproof ability testing system of a three-directional loaded shield tunnel duct piece joint seam, belonging to the technical field of shield tunnels. The system comprises a self-balance frame subsystem, a load and deformation control subsystem, a testing piece conveying subsystem, an operating subsystem and a data acquisition subsystem, wherein the balance frame subsystem and the load and deformation control subsystem are connected by screw bolts; the balance frame subsystem and the testing piece conveying subsystem are connected by screw bolts; the load and deformation control subsystem and the operating subsystem are connected by leads; and the load and deformation control subsystem and the data acquisition subsystem are connected by leads. Through different combinations of the load and deformation control subsystem, the waterproof ability test to transverse seams, T-shaped seams and cross seams of shield tunnel duct pieces can be accomplished.

Description

technical field [0001] The invention belongs to the technical field of shield tunnels, and relates to a three-way loaded shield tunnel segment seam waterproof capability test system. Background technique [0002] Shield tunnel is a special underground structure whose main structure is composed of segments. The segment rings are connected by circumferential bolts to form a segment ring, and the segment rings are connected by longitudinal bolts to form a tunnel structure. Since the tunnel lining structure is composed of segments assembled, there are a large number of longitudinal and annular joints between segments and segment rings. Therefore, tunnel leakage is more common. Shield tunnels are generally built in soft soil rich in groundwater. Leakage in the tunnel will cause surrounding water and soil loss, resulting in changes in water and soil pressure around the tunnel and uneven settlement of the tunnel. The safety of the structure poses a great threat. As the permanent...
