Abstract

The invention discloses a loading system of a shield segment testing machine. The loading system of the shield segment testing machine comprises a self-balancing counter-force core tube and a radial force loading device. The radial force loading device is arranged on the outer side of the self-balancing counter-force core tube and located between rings assembled by shield segments. The self-balancing counter-force core tube is composed of an upper covering board, an upper hoop, a middle hoop, a lower hoop and vertical beams. The upper covering board is located at the top of the self-balancing counter-force core tube. The multiple vertical beams which are the same in shape and size are arranged at intervals along the same circumference. The upper hoop is located at the upper portion of the outer side of the circumference of the multiple vertical beams; the middle hoop is located in the middle of the outer side of the circumference of the multiple vertical beams; the lower hoop is located at the lower portion of the outer side of the circumference of the multiple vertical beams. The loading system of the shield segment testing machine has the advantages of being small in floor space, low in cost, wide in application range and the like.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a loading system of a shield segment testing machine and a shield segment testing machine. Background technique [0002] The shield segment is the main assembly component of shield construction and the outermost barrier of the tunnel, which bears the role of resisting soil pressure, groundwater pressure and some special loads. The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel. [0003] In order to check the quality of the shield segment, the shield segment test equipment is usually used to test the performance of the shield segment. [0004] The loading system is an important part of the shield segment testing machine. In the prior art, a reaction force wall is usually used to pro...
