specific Embodiment

[0055] For specific examples, see figure 1 , a method for testing and appraising the construction quality of an exterior wall waterproofing project, characterized in that the steps are:

[0056] The first step, on-site investigation

[0057] The content of the on-site investigation includes the following aspects:

[0058] 1) Construction design, water supply and drainage system, maintenance and other basic conditions of exterior wall engineering;

[0059] 2) Type of exterior wall;

[0060] 3) Leakage location, leakage history, leakage status and degree, and change law of leakage water;

[0061] 4) The impact of the surrounding environment, operating conditions, climate change and natural disasters on the project location;

[0062] The second step is to investigate the leaking part of the external wall

[0063] Use observation and leakage inspection methods to detect and partially dismantle concealed projects, find the traces of leakage parts and leakage range from the inn...

Abstract

The invention relates to an exterior wall waterproof project construction quality inspection and identification method, in particular, a leakage inspection and identification method for the exterior wall waterproof construction examination and acceptance of projects under construction and the exterior wall waterproof project of existing buildings. According to the exterior wall waterproof projectconstruction quality inspection and identification method of the invention, a leakage inspection method, an infrared thermal imaging method and a microwave humidity method are combined with on-site verification so as to inspect and identify the cause of the leakage of external wall projects. The method has the advantages of high reliability, scientific judgment, accurate and reliable conclusions,scientific and rigorous steps, and simple and reliable detection steps, and is suitable for being popularized.

Description

technical field [0001] The invention relates to a method for detecting and appraising the construction quality of an exterior wall waterproofing project, in particular to a leak detection and appraisal method for the acceptance of exterior wall waterproofing construction of a project under construction and the waterproofing project of an existing building exterior wall. Background technique [0002] In 2014, the survey report of the China Building Waterproof Association showed that there were 2,849 buildings in 28 cities and 850 communities across the country, and 2,849 building samples were sampled. 2,716 of the building samples had leakage to varying degrees, and the leakage rate reached 95.33%. my country's annual waterproofing project repair cost exceeds 1.2 billion yuan, causing huge economic losses to the country. [0003] With the development of construction technology and the improvement of people's living standards, the requirements for the residential environment ...
