Abstract

The invention discloses an upper reaction support system for shield-semi-ring origination, and provides a construction method for shield-semi-ring origination based on the support system. The supportsystem includes a reaction force frame, and further includes a support plate and a plurality of support rods; the support plate is fixed on the rear side of a nearest integral ring segment, and the support plate corresponds to the shape, size, and position of the part of the nearest integral ring segment which exceeds semi-ring segments; and one ends of the support rods are separately fixedly connected with the reaction force frame, and the other ends of the support rods are separately connected with the support plate in a hinged mode. According to the upper reaction support system and a construction method for the shield-semi-ring origination, the support plate serves as a connecting hinge from semi rings to integral rings to play a fixed and stable role, and since the other ends of the support rods are hinged to the support plate, so that the force bearing point and direction of the support position can be adjusted; and thus the smoothness and ellipticity of assembly of the semi-ringsegments and integral ring segments can be ensured, thereby ensuring the origination attitude of a shield tunneling machine.

Description

technical field [0001] The invention relates to the field of tunnel excavation and construction by shield tunneling method, in particular to an upper reaction force support system for starting half-rings of shield tunneling and a construction method for starting half-rings of shield tunneling. Background technique [0002] Shield tunneling has a history of more than 100 years, and after nearly half a century of rapid development, it has matured day by day. In domestic underground engineering construction, the shield tunneling method has been widely used in urban underground rail and underground pipeline projects due to its advantages of safety, high quality, high efficiency, environmental protection, and low labor intensity. [0003] Among them, the semi-ring starting is a special starting method adopted by the shield machine due to the limitation of the length, width and hoisting hole of the shield tunnel. The half-ring means that only the lower half ring is installed on th...
