AI Technical Summary

Technical Problem

When the existing technology seals the holes through the wall of the external wall bolts, the cement mortar filling is not dense enough and the seal is not reliable, and there is a large risk of leakage and moisture reflux, which fails to fundamentally solve such problems.

Method used

By amplifying the holes, a flare-shaped expansion section is formed, the working area and contact area are increased, and a multiple waterproof sealing structure is set up, including water-stop glue strips, waterproof mortar, waterproof coatings and foaming materials to form a multiple waterproof sealing mechanism.

Benefits of technology

It significantly improves the waterproof effect, reduces leakage risks, enhances the convenience of construction, and has a long-lasting sealing effect, can withstand various climatic conditions, and reduces maintenance costs.

Abstract

The invention discloses a construction method for blocking a screw rod hole of a wall body, which mainly comprises the following steps of: firstly, expanding and cleaning a hole; sequentially installing a water stop adhesive tape, pouring waterproof mortar and constructing waterproof paint, coating the waterproof paint on the outer wall surface of the wall body to cover the hole, then filling a foaming material, blocking by using dry and hard mortar, and finally checking and accepting; according to the construction method for plugging the screw rod hole of the wall, the hole is expanded before plugging construction, so that the operation area is increased, the operation difficulty is reduced, the filling volume of the waterproof material is increased, multiple waterproof plugging structures are arranged, and the waterproof effect is remarkably improved.
