Problems solved by technology

[0003] The walls of real estate buildings need to have a certain waterproofness to avoid the penetration of water. The penetration of water into the walls not only affects the normal use of the building, but also corrodes the walls, resulting in a decrease in strength and shortening the service life of the building.
[0004] In the real estate evaluation, it is necessary to test the water seepage performance of the wall. The usual method is to use a water pipe to spray water on the wall from top to bottom for a period of time, and then go to the other side of the wall after a period of time to observe whether there will be water seepage Phenomenon, due to the low detection efficiency and the phenomenon of water seepage is not intuitive enough, the effect of water seepage detection is not good

Embodiment 1

[0047] see figure 1 , a method for detecting water seepage on a wall surface of a real estate building, comprising the following steps:

[0048] S1. Clean the wall to be detected, then spray the detection liquid to wet the wall, and wipe off the liquid on the surface;

[0049] S2. Carry out film covering treatment on the wall surface to keep the film covering flat and fit without bulging;

[0050] S3. Heat the wall evenly as a whole, and observe whether there is a bulge in the coating. If there is a bulge, there is water seepage in the area. If there is no bulge, there is no water seepage area on the wall;

[0051] S4. Uncover the covering film and perform waterproof treatment on the seepage area.

[0052] see figure 2 , In the prior art, there is a method of spraying water for wetting and blowing dry for detection, but the method of blowing dry is easy to cause interference to the permeated water, and secondly, the effect of the permeated water is not obvious enough to be...

Embodiment 2

[0057] see Figure 4 In step S2, the coating adopts the detection film layer 1, and the detection film layer 1 includes a plurality of detection units.

[0058] see Figure 5-7 , the outer tympanic membrane 11 and the inner osmotic membrane 12 are symmetrically distributed, and the air barrier membrane 13 is surrounded and connected between the outer tympanic membrane 11 and the inner osmotic membrane 12, the detection ball 14 is connected to the inner surface of the inner osmotic membrane 12, and the deformation rod 15 is connected between the outer gas membrane 11 and the detection ball 14. When the detection liquid is heated and releases gas, the gas passes through the inner osmosis membrane 12 and enters the inner space to inflate continuously, and then forces the outer gas membrane 11 to expand and bulge. Furthermore, the detection ball 14 is pulled by the deformation rod 15 to release the functional material liquid 143 to mark or repair the seepage area.

Abstract

The invention discloses a wall surface water seepage detection method for a real estate building, which belongs to the technical field of building detection. According to the wall surface water seepage detection method, a detection liquid is sprayed to a to-be-detected wall surface to wet the surface, then the detection liquid on the surface is wiped to be dry, interference to subsequent detection is avoided, then film covering is conducted till the surface is flat, and overall uniform heating is conducted; if a water seepage phenomenon exists, detection liquid in a wall surface can release gas to escape after being heated, and the gas cannot be discharged when encountering a film, a hollowing phenomenon can be formed in a corresponding area, the hollowing phenomenon can be visually observed by technicians, meanwhile, the water seepage area can be accurately positioned, and later waterproof treatment is facilitated; and the water seepage detection efficiency and effect of the wall surface can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of building detection, and more specifically, to a method for detecting water seepage on a wall surface of a real estate building. Background technique [0002] Real estate is a comprehensive and complex concept. From the perspective of physical phenomena, it is composed of buildings and land. Land can be divided into undeveloped land and developed land. Buildings exist attached to the land and are combined with the land. Buildings refer to the products of artificial construction, including two categories: houses and structures. [0003] The walls of real estate buildings need to have a certain waterproofness to avoid the penetration of water. The penetration of water into the walls not only affects the normal use of the building, but also corrodes the walls, resulting in a decrease in strength and shortening the service life of the building. [0004] In the real estate evaluation, it is necessary to test ...
