Detection methods of old houses and dangerous houses

It is very necessary to detect dangerous buildings in old houses, because there are certain dangers in old houses, such as cracks in walls, water leakage in houses, aging wires and so on. If these problems are not found and solved in time, it may lead to serious consequences such as fire, explosion and collapse, which will bring danger to residents' lives and property.

In order to ensure the scientific and accurate detection of old houses and dangerous houses, here are some commonly used detection methods.

1. Sampling detection method. Select some components for testing, such as walls, columns, beams, etc. Its quality and strength are determined by destructive test, laboratory test and other methods.

2. On-site detection method. On-site inspection, such as the use of radar, ultrasonic, X-ray and other nondestructive testing methods, to detect the thickness, material, damage, etc. of walls, columns and other parts, so as to judge their quality and strength.

3. Appearance inspection method. Through the inspection and observation of the appearance, roof, walls, doors and windows, ground and other parts of the house, it is found whether there are defects and hazards, such as water leakage, cracks and potholes.

4. Test instrument method. Use professional testing instruments, such as metal detectors, water meters, electricity meters, gas meters, etc. , check whether the water, electricity, gas and other facilities inside and outside the house are normal, and eliminate potential safety hazards.

In addition to the above detection methods, we can also refer to the relevant national standards and technical specifications, and regularly detect old houses and dangerous buildings according to the requirements of scale, materials, strength and construction quality to ensure the safety of houses.
