Detection and leakage blocking methods of concrete building water leakage

Abstract

The present invention discloses a detection method of concrete building water leakage. The method comprises the steps of (1) current condition visual examination, (2) current condition measurement record, (3) aspiration measurement change, (4) the connection of a wave metre and an infrared detector, the determination of the position of a water leakage source and a water leakage path, and the determination of a water leakage serious degree by using the wave metre. The invention provides a leakage blocking method which comprises the steps of (1) drilling a waterproof layer grouting hole, (2) carrying out grouting to make a new waterproof layer, (3) making a leakage repairing reinforced grouting hole in concrete, (4) carrying out internal leakage repairing reinforced grouting, (5) sealing the water inlet of a water leakage source, and filling a water leakage path according to the water leakage serious degree. Compared with the prior art, the methods have the advantages that by using the detection and leakage blocking methods, the leakage blocking method is excellent, the defect degree of an existing concrete structure is accurately judged and the reinforcement of the concrete structure at a later period can be accurately repaired, and thus the durability of concrete is improved to play a significant role.

Description

technical field [0001] The invention relates to a measurement technology and a reinforcement and repair method, in particular to a method for detecting and plugging water leakage in concrete buildings. Background technique [0002] At present, for concrete buildings, the leak detection and plugging method that uses more leaks is Japan's Jiang Tian type leak diagnosis and repair system. [0003] Jiangtian-style water leakage diagnosis method, using carbon dioxide (CO 2 ) sensory method to detect the source of water leakage. The steps are: firstly drill a hole in the leaking part of the concrete building, send in carbon dioxide gas, and then conduct gas sensing outside the building, that is, carry out detection of sending in carbon dioxide gas at the part that is preliminarily judged to have a higher possibility of water leakage. know the measurement. Finally, according to the sensing condition of the gas sensor, the source of the water leakage, that is, the position of the...

Problems solved by technology

If the tester does not have high knowledge of building structure and corresponding technology and experience, he often does not know where to start in actual operation. Even if the gas sensor captures a certain concentration of gas induction in a certain part, it may not be sure that the is the exact location of the leak

Second, because this measurement method uses local point measurement, the efficiency is low, and the effect is not significant in the diagnostic detection of large-area water leakage.

[0006] Although the Jiangtian-style plugging method is a relatively economical repair method, since it is only a plugging method that mainly fills gaps and cavities, it does not provide structural reinforcement for cracks in concrete. Reinforcement compensation for strength loss
