Water leakage repairing process for air face

Abstract

The invention discloses a water leakage repairing process for an air face. The water leakage repairing process for the air face comprises the following steps: cutting a brick wall built on a wall bodyof the air face at first to form a construction portion; then coating an interface waterproof agent; planting bars between upper brick bodies and a lower concrete floor of the construction portion; pouring expand anti-permeability concrete; after the concrete is solidified, chiseling out a 'V'-shaped groove in an internal corner portion; then coating the interface waterproof agent; sealing the 'V'-shaped groove by using a waterproof sealant; reinforcing and blocking the internal corner by using repairing mortar, wherein the internal corner has arc-shaped gradient; then brushing a first air face waterproof coating; adding anti-cracking polyester textile on a connection portion between the internal corner and the wall body on the top; then brushing a second air face waterproof coating; whitewashing flatly by using repairing mortar; finally, laying ceramic tiles by using wet mortar after coating the ground portion with ceramic tile glue; and scraping and flattening a wall surface portionby using an external wall putty coating. By structural design, various waterproof materials are combined to a process, and thus, the problem of water leakage of the air face is solved systematacially.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a technique for repairing leaking water on the back surface. Background technique [0002] The inner corner of the wall is a special part that is prone to leakage. The main reasons for the leakage are as follows: [0003] (1) The deformation of the building is too large, exceeding the allowable deformation range, mainly due to thermal expansion and contraction and uneven settlement of the foundation. [0004] (2) The rapid displacement of the inner corner of the wall during the construction process causes waterproof failure. [0005] ⑶ Due to the lack of compactness when pouring concrete, phenomena such as looseness, dog holes, and honeycombs have occurred, forming channels for water leakage. [0006] ⑷Water leakage caused by damage to waterproofing during construction. [0007] It is worth noting that the information disclosed in this background technology is only inte...
