Prefabricated box culvert structure connection rapid positioning device for shield tunnel

Abstract

The invention discloses a prefabricated box culvert structure connection rapid positioning device for a shield tunnel, and relates to the technical field of shield tunneling. The prefabricated box culvert structure connection rapid positioning device comprises a prefabricated box culvert body, wherein four pipe pieces arranged in a circumferential mode are placed on the periphery of the prefabricated box culvert body, a notch is formed in the upper surface of the prefabricated box culvert body, two symmetrical first steel plates are placed on the inner bottom wall of the notch, the two first steel plates are fixedly connected with the two pipe pieces located on the uppermost portion respectively, and the front side faces and the rear side faces of the first steel plates make contact with the front inner wall and the rear inner wall of the notch. According to the prefabricated box culvert structure connection rapid positioning device for the shield tunnel, two second steel plates can drive two right-angle limiting plates to get close to each other by starting a forward and reverse rotation motor, so that the prefabricated box culvert body is rapidly positioned, a first filling plate and a second filling plate can be taken out by pulling a first pull ring and a second pull ring, therefore, the pipe pieces are convenient to detach, and therefore, the problems proposed in the background technology are solved.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to a fast positioning device for connecting prefabricated box culvert structures for shield tunnels. Background technique [0002] Shield tunneling is a fully mechanized construction method in underground excavation construction. It pushes the shield tunneling machine in the ground, supports the surrounding rock through the shield casing and segments to prevent collapse into the tunnel, and simultaneously excavates The soil body is excavated by cutting device in front of the front, transported out of the hole by excavation machinery, pushed in by jack at the rear, and assembled with precast concrete segments. [0003] The prefabricated box culvert structure used in the shield tunnel is difficult to connect the fast positioning device to the prefabricated box culvert structure, and errors are prone to occur in the fabrication and assembly of the shield segment and the prefab...
