Description

Technical Field

[0001] The utility model relates to the technical field of subway construction, in particular to a subway construction supporting device. Background Art

[0002] With the development of society and the popularization of automobiles, the amount of subway construction in various parts of my country is increasing year by year in the context of increasingly congested road traffic. Support engineering is the most important stage in the early stage of subway construction. During the shield construction of the subway, the excavated tunnel needs to be supported and protected to prevent its collapse and leakage. The existing support and protection structure usually uses prefabricated reinforced concrete components for support and laying. In the process of supporting and laying the components, it is necessary to build corresponding support devices for support to ensure the forming and laying of the supporting components. The existing support devices, such as the Chinese patent with publication number CN209621345U, propose a support device with adjustable height, but the shock absorption effect of the support device is insufficient and cannot meet the needs of construction support. The Chinese patent with publication number CN213296374U proposes a support mechanism with adjustment function, but it cannot meet more work requirements, which has a great impact on the construction progress of the subway.
