Method for tunnel vault grouting construction with template

A method for tunnel vault grouting construction with a template comprises the following steps of lining trolley mounting, grouting pipe length determining, grouting pipe mounting and fixing, vault template interior concrete grouting observation, special filling mortar preparation, mortar preparation and grouting integrated machine starting for grouting, grouting finishing and flange dismounting. According to the method, through the technology of grouting with the template and micro-expansive and high-flowability concrete grout, the adhesive strength is high, the repairing effect is achieved onsection gaps formed by concrete pouring, and the comprehensive property of the concrete grout is superior to the property of lining concrete; the risks of tunnel lining concrete cracking, disengagingand falling off are reduced, the immunity of a tunnel lining to the geological risk is increased, the disaster occurrence risk of the tunnel lining during operation is reduced, construction can be completed at a time, and thu
