Abstract

The present invention provides a prefabricated platform and its installation method. The prefabricated platform includes a bearing body and a number of reserved cast-in-place grooves arranged in the bearing body. The surface extends into the carrying body, and the maximum vertical height of the prefabricated platform is less than or equal to the maximum vertical height of the transport platform. In the installation method of the prefabricated platform provided by the present invention, the synchronous installation of the segment and the prefabricated platform is realized by first installing the segment and then correspondingly installing the prefabricated platform, which solves the problem that the concrete is restricted by the environment during the construction of the transportation channel in the shield tunnel At the same time, when the maximum vertical height of the prefabricated platform is less than the maximum vertical height of the transportation platform, the transportation channel can be formed by reserving a cast-in-place trough to cast in-situ concrete, thereby The formation of the transportation channel is optimized as a method of prefabrication and cast-in-place, which improves the construction efficiency.

Description

technical field [0001] The invention relates to the technical field of shield tunneling engineering construction, in particular to a prefabricated platform and an installation method thereof. Background technique [0002] With the rapid development of urban infrastructure construction, more and more traffic arteries and important pipelines are developed underground. As a construction technology with the least impact on the ground and the least environmental restrictions, the shield tunneling method is widely used. However, the tunnel formed by the shield tunneling method is usually segmented lining to form a shield tunnel due to the limitation of the existing technology and construction cost, and if the shield tunnel is used for construction such as automobile walking, train operation, pipeline laying, etc., due to The mass of large equipment such as automobiles is very large, and it is easy to damage the segments and the shield tunnel. In order to avoid this situation, it i...
