Abstract

The embodiment of the invention discloses a construction method for an artificial paved tunnel secondary bracing reinforcing mesh and a paving rack. The paving rack comprises a liftable portal and a liftable arc-shaped support frame arranged on the top of the portal; an arc-shaped support plate is matched and connected with the top of the arc-shaped support frame; a plurality of longitudinal grooves for loading longitudinal reinforcements are formed on the arc-shaped support plate along forward and backward directions; rotatable and stretchable mechanical arms used for paving circumferential reinforcements and longitudinal reinforcements are respectively arranged on front and rear ends of the portal; a rotating motor used for supplying power to the rotatable and stretchable mechanical armsis arranged on the portal; horizontal telescopic booms used for finishing arc-shaped transformation of the circumferential reinforcements are respectively arranged on the two ends on the top of the portal; stirring arms used for stirring head and tail ends of the circumferential reinforcements are respectively arranged on the middle parts of the two ends of the portal.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of tunnel construction, and in particular to a construction method and a laying stand for imitating manual laying of the steel mesh for the second lining of the tunnel. Background technique [0002] It is well known that the laying of steel mesh in the construction process of the second tunnel lining concrete is a heavy manual labor with high risk. [0003] At present, the steel mesh for the second lining of the tunnel is laid: after the steel bars are placed on the platform, they are manually pushed to the rock face of the tunnel for binding. [0004] In the longitudinal reinforcement method, a winch or the operator stands on the platform by steps, and the longitudinal reinforcement is placed on the platform in a relay manner. After the hoop reinforcement is laid in place, the longitudinal and hoop bindings are connected to form a reinforcement mesh. [0005] There are two types ...
