specific Embodiment

[0044] For specific examples, see figure 1 , a roof waterproofing construction quality inspection and identification method is characterized in that its steps are:

[0045] The first step, on-site investigation

[0046] The content of the on-site investigation includes the following aspects:

[0047] 1) The basic situation of roof construction design, water supply and drainage system, maintenance, etc.;

[0048] 2) Roof type;

[0049] 3) Leakage location, leakage history, leakage status and degree, and change law of leakage water;

[0050] 4) The impact of the surrounding environment, operating conditions, climate change and natural disasters on the project location;

[0051] The second step is to investigate the leaking part of the roof

[0052] Use observation, measurement, and partial demolition of concealed works to find the traces of the leakage site and leakage range from the bottom of the roof slab to understand the degree of leakage; find the cause of suspected le...

Abstract

The invention relates to a roof waterproof project construction quality inspection and identification method in particular, a leakage inspection and identification method for the roof waterproof construction examination and acceptance of projects under construction and the roof waterproof project of existing buildings. According to the roof waterproof project construction quality inspection and identification method of the invention, an infrared thermal imaging method, a microwave humidity method and a metal roof upward-lift force water spray test method are combined with on-site verificationso as to inspect and identify the cause of the leakage of roof 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 a roof waterproofing project, in particular to a leak detection and appraisal method for the inspection and acceptance of the roof waterproofing construction of a project under construction and the roof waterproofing project of an existing building. 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 my country's construction technology in recent years, large-span, light-weight and high-rise buildings are increasing day by day, so...
