Multi-material composite plugging and waterproofing method based on forming non-curing material

Abstract

The invention provides a multi-material composite leaking stoppage waterproof method based on a formed non-cured waterproof material, and relates to the technical field of crack repairing, leaking stoppage and water resistance. The method comprises the steps that firstly, the foundation surface of a crack structure is cleared, the crack condition is checked and analyzed, drilling is carried out onthe two sides of a crack in an intersecting mode, and temporary leaking stoppage is carried out by pouring a polyurethane grouting material; the surface of the crack structure which is subjected to temporary leaking stoppage is cleared; the non-cured waterproof material is attached to the surface of the crack structure along the crack; the non-cured waterproof material is heated and extruded to be tightly attached to the wall of the crack structure; the upper side of the formed non-cured waterproof material is coated with an epoxy resin impregnating adhesive, and carbon fiber cloth is correspondingly pasted in the longitudinal and transverse directions; and the surface of the carbon fiber cloth is coated with the epoxy resin impregnating adhesive again. According to the multi-material composite leaking stoppage waterproof method, the construction process is convenient and fast to implement as well as safe and reliable, the adopted materials are light, non-toxic and environment-friendly, the operation time is shortened, and the labor intensity of workers is reduced; and a reinforced body composed of the carbon fiber cloth and epoxy resin improves the high water pressure resistance, and reduces the damage and disturbance on the structural wall.

Description

technical field [0001] The invention relates to the technical field of crack repair plugging and waterproofing, in particular to a multi-material composite plugging and waterproofing method based on formed non-cured materials. Background technique [0002] Cracks in tunnels and underground projects often occur during their operation or use, especially in traffic tunnels. Due to the need to meet the traffic requirements of vehicles and pedestrians, the construction window for plugging is short, and the construction quality requirements are high. The durability of the structure is high, and the appearance is high. [0003] Existing tunnel and underground engineering leak plugging technology mainly contains two ideas. One is an inorganic grouting plugging method, such as ultrafine cement grouting and cement water glass grouting. The principle of this method is to drill through the structural layer, bury the grouting pipe, and then inject inorganic fast-setting waterproof mate...
