Method to Prevent Cracks in Buried Pipes after Masonry

Abstract

The invention discloses a method for preventing a masonry rear embedded wire tube position from cracking. The method is characterized by comprising the following steps of wire tube arrangement construction, wire slot closing construction, a wall body plastering construction, wire tube position pasting glass fiber cloth construction, wherein the process of the wire tube position pasting glass fiber cloth construction is as follows: the plastering mortar surfaces on two sides of a wire tube position are grinded, a pasting range is determined according to a wire tube marking line, a primer is coated within the pasting range, glass fiber cloth is pasted, a scraper plate is utilized to properly exert pressure so as to enable a cloth tape to be fully cleaned, then face glue is coated, and roughening or protection treatment is conducted on the surface of the glass fiber cloth after the glue is dried or cured. The method has the advantages that based on a traditional construction method, the cracking problem produced due to poor closing mortar bonding and stress concentration by means of the traditional method can be effectively controlled by pasting the glass fiber cloth tape on the outside of a wire tube; the method is simple and convenient to construct, low in cost, very ideal in wire tube position crack control effect and worthy of popularization and application.

Description

technical field [0001] The invention relates to a method for preventing cracks, in particular to a method for preventing cracks at the position of buried pipes behind masonry, and belongs to the technical field of construction. Background technique [0002] The laying of wall pipes in brick masonry usually adopts the post-buried method, that is, on the masonry wall, according to the design or the requirements of the residents, use electric tools and hand chisel to remove, and carve a certain depth and width on one side of the wall. The U-shaped groove, and then place the line pipe and seal it with mortar and other materials. [0003] After investigation, according to the traditional method of laying construction, there are still some cracks in the wall line pipe of some projects. If the vertical line pipe is close to the middle of the wall, most of the cracks will penetrate the wall thickness. [0004] At present, there are three common methods for preventing cracks in buri...

[0013] 2. There is no reinforced mesh belt outside or the effect of reinforced mesh belt is not good

However, practice has proved that using it to control the wall cracks at the post-buried pipe is the same as controlling the cracks at the joint between the post-filling wall and the main structure, and the effect is not very ideal.
