Detection method of rainwater leakage path in buildings

Abstract

The invention discloses a test method of a rain-leaking path of buildings. The test method is characterized by comprising the following steps: a. punching a hole in an inner wall at the center area of water seepage position, wherein the depth of the hole is half of the thickness of the wall; b. inletting water vapor into the hole continuously and sealing the hole; c. observing an outer wall surface, continuing to inlet water vapor for three to five minutes when a wet area appears on the outer wall surface, until obvious wet trace appears on the outer wall surface, and determining the wet trace area as water seepage position finally. The test method of the rain-leaking path of the buildings has the advantages that device is simple, rain-leaking position is tested only through tube connection, rain-leaking position is recognized with human eyes, effect is obvious, and good test effects are achieved no matter on site test or in laboratory. Further, simple and few devices are used, invested cost of test is lowered greatly, and rain-leaking position of the wall is recognized accurately.

Description

Technical field [0001] The present invention relates to external detection on structures such as roofs, walls and floors in buildings [0002] The method of creating a leaky path. Background technique [0003] It is difficult to determine and detect rainwater paths inside structures such as walls, floors, and pillars of buildings, and it is especially difficult to detect rainwater leakage paths on walls on site. At present, some equipment is used for this work, but it is not satisfactory and cannot be promoted. For example, the invention patent filed by Tongji University on June 28, 2001, its patent application number is 01113148.9, and the name of the invention is on-site inspection equipment and method for external wall impermeability. It is a simulation of wind and rain inspection, the structure is complicated, and the inspection process is troublesome. On May 20, 2004, Japan Eda Eyueken applied for a patent for invention. Its patent application number is 200410045320.5. The n...
