Embodiment Construction
[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0033] Rail transit has the characteristics of large capacity, fast speed, safety, punctuality, environmental protection, energy saving and land use. Rail transit has been developed into a backbone urban public transportation system.
[0034] During the construction of rail transit, a large number of shield segments are required. For example, Xiamen Rail Transit Line 1, as the most important central radial backbone line in the planning network of Xiamen City, radiates from the island to the north to form a cross-sea tunnel. The fast connection channel has a line length of 32.865km, 15.7km on the main island and 17.165km outside the island. Among them, the length of the shield construction section is about 25km, and the shield segment is about 20...

Abstract
The invention discloses an intelligent flow production line for shield segment prefabrication. Mold propelling systems in the production line are arranged on a pouring production line body and curing production line bodies respectively and push segment molds on the production line bodies to move. Transverse moving ferrying systems are matched with the pouring production line body and the curing production line bodies and used for conveying the molds from the pouring production line body to the curing production line bodies or conveying the molds from the curing production line bodies to the pouring production line body. A concrete feeding system is matched with a concrete pouring system and used for conveying concrete to the concrete pouring system. The concrete pouring system is arranged on the pouring production line body and used for completing segment pouring forming. An intelligent steam curing control system is used for conducting steam curing control on segments on the curing production line bodies. A programmable logic controller (PLC) automatic control system coordinates mutual matching among the systems, so that automation of shield segment prefabrication is achieved. The intelligent flow production line is stable in performance, good in reliability, easy to maintain and good in safety performance and meanwhile has the characteristics of being automatic and high in informationization degree and production efficiency.
Description
technical field [0001] The invention relates to segment prefabrication technology, in particular to an assembly line for shield tunnel segment prefabrication. Background technique [0002] The shield segment is the main assembly component of shield construction and the innermost barrier of the tunnel, which bears the role of resisting soil pressure, groundwater pressure and some special loads. The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel. [0003] The production of shield segments usually uses high-strength impermeable concrete to ensure reliable load-bearing and waterproof performance. The production mainly uses the finished segment mold to form after sealing and pouring concrete. [0004] With the vigorous development of tunnels and rail transit, a large number of shield seg...
