Problems solved by technology

[0004] Another purpose of the present invention is to provide an articulation system of the shield machine that can be used according to the construction requirements after most of the hinged cylinders of the shield machine fail, and the maintenance is difficult. The device effectively connects the cylinder body of the articulated cylinder to the base of the cylinder, thereby adjusting the elongation of the articulated cylinder so that the articulated angle reaches the expected value, ensuring that the impact on cost and construction period control can be greatly reduced after a large-scale failure of the articulated cylinder

Abstract

The invention discloses an auxiliary device for adjusting the articulation angle of an articulation cylinder of a shield tunneling machine and a construction method thereof. The auxiliary device comprises a basic block and a plurality of small blocks. Formed by two removable semi-circle cylinders, the basic block is in the structure of a hollow circular cylinder and arranged outside a piston rod of an articulation cylinder in a sleeve mode. Each small block is in the structure of a square plate, wherein one side of the small block is concaved inwards to form a groove which is disposed on the piston rod of the articulation cylinder in a clamping mode. The auxiliary device enables the articulated system of the shield tunneling machine to work according to construction requirements after a malfunction of the articulation cylinder, and efficiently connects the articulation cylinder body and the articulation cylinder seat, accordingly the articulation angle can reach the expected value, and the influence on the control of cost and construction progress can be greatly reduced after a large-scale malfunction of the articulation cylinder.

Description

technical field [0001] The invention relates to the field of shield method construction in tunnel engineering construction technology. More specifically, the present invention relates to an auxiliary device for adjusting the articulation angle of an articulation cylinder of a shield machine and a construction method thereof. Background technique [0002] With the large-scale development of domestic subway construction, the shield construction method is widely used in the construction of subway sections due to its characteristics of safety, speed, and wide adaptability. At present, the mainstream shield machines in the world must use hinges in the process of small curve construction to ensure a good posture. Therefore, when the hinge system fails, it will have a great impact on the attitude adjustment of the shield machine and the construction of the curved section. Moreover, the hinge system is installed in the shield body, and the inner space of the shield body is relativ...
