Abstract
Description
Technical Field
[0001] The present application relates to the technical field of tunnel construction, and in particular to a tunnel lining concrete spraying and curing device. Background Art
[0002] After tunnel excavation, the original balance of the strata around the tunnel is destroyed, causing the tunnel to deform or collapse. In order to protect the stability of the surrounding rock and ensure driving safety, the tunnel must have a support structure of sufficient strength, namely the tunnel lining.
[0003] Tunnel lining is a permanent support structure built with reinforced concrete and other materials along the perimeter of the tunnel to prevent deformation or collapse of the surrounding rock. Different lining forms can be used for different surrounding rocks. Common lining forms include shotcrete lining, shotcrete anchor lining and composite lining. Composite lining is used in most cases. Composite lining is often divided into initial support (primary lining) and secondary support (secondary lining).
[0004] In the prior art, in order to ensure the quality of the lining, the lining is generally maintained, and the maintenance generally involves spraying water to keep the lining moist and prevent the concrete from shrinking and deforming. The general maintenance spraying mostly uses a trolley, but the use of a trolley requires a large-section gantry to be manufactured according to the cross-section, which is costly.
