PVC protective lining and its construction and construction leak detection method

Abstract

The invention discloses a PVC protection lining and a construction and construction leakage detecting method thereof. The PVC protection lining comprises a lining body; and a T-shaped fixed key projected on the surface of the lining body is arranged on one side, towards reinforced concrete, of the lining body. The PVC protection lining is characterized in that a T-shaped fixed key beneficiation combination cavity is formed on the top surface of the T-shaped fixed key in the length direction of the T-shaped fixed key. The method comprises the following steps: one side, with the T-shaped fixed key, of the lining body faces to the reinforced concrete after pouring, and the T-shaped fixed key is inserted in the reinforced concrete; the edge parts in long edge directions of two adjacent lining bodies are overlapped, and the edge parts in short edge directions are overlapped; long edge leakage detection electric conducting metal wires are inlaid in the long edge joint overlapping area, and short edge leakage detection electric conducting metal wires are inlaid in the short edge joint overlapping area; and a hot air welding gun is used for welding. The reliable and everlasting combination effect with the reinforced concrete is improved; the conditions are created for the leakage detection after construction; and the leakage points in the long and short edge joint overlapping areas after hot welding welding can be detected.

Description

technical field [0001] The invention belongs to the technical field of building components and construction thereof, and in particular relates to a PVC protective lining, and also relates to its construction and a construction leak detection method. Background technique [0002] The aforementioned PVC protective lining is also called PVC protective lining or anti-corrosion lining, and is widely used in municipal facilities projects, urban and rural sewage treatment projects, tunnels, subways, underground civil defense projects, underground garages of urban buildings, building roofs, and military facilities. Applications such as aircraft hangars, reservoirs, swimming pools and agricultural ditches. In the early days, measures such as painting protective film, laying waterproof membranes, and pouring surface protective layers were generally used for anti-leakage protection not limited to the occasions listed above. The shortcomings lie in the large amount of engineering work, ...

Problems solved by technology

However, due to the inability to verify the reliability of the sealing of the overlapping parts bonded together, it was only discovered after the project was put into use, that is, when it leaked during service, but it was too late

There are currently two ways to deal with it: one is to use a plugging agent to stop the leak when the degree of leakage is slight; the other is to implement rework when the degree of leakage is serious, which not only increases the cost of daily management and maintenance due to repeated labor input, Moreover, it causes a waste of resources, because rework must discard old cloth and new ones

The applicant has noticed the records in the 11th to 14th lines of the third paragraph of the second page of the CN201428867Y specification: "A special instrument for checking the tightness of the lining is also designed, and the joints of the PVC material in each section of the pipe and the connection between the pipes and the pipes are also designed. Check the joints of the lining at the same time to ensure the tightness of the lining, thereby ensuring to improve the life of the reinforced concrete pipe", but did not give specific enlightenment on how to check the tightness
