Abstract

The invention discloses a grouting device and method of external sealing and back pressure for concrete water seepage treatment. The grouting device comprises external sealing steel plates, pressure air nozzles, grouting nozzles, elastic sealing strips, a pressing and pasting fastener and a pressing and sealing fastener. According to the grouting device, when concrete water seepage treatment is conducted, one or more external sealing steel plates pasted with the elastic sealing strips at periphery are sealed on the concrete water seepage surface by adopting expansion bolts, back pressure grouting treatment of concrete water seepage appearance after full sealing can be achieved, a fast-setting and early-strength expoxy grout with good permeability is adopted by grouting, the pressure air nozzles and the grouting nozzles are arranged on the external sealing steel plates, a mixed grouting technology of pressure air and pressure grouting is carried out, the concrete water seepage can be effectively filled, permeated and consolidated from outside to inside, and the double effects of waterproof and leakage plugging and structural repair of the leakage defects of concrete structures are achieved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a concrete water seepage treatment external seal back pressure grouting device and a grouting method. Background technique [0002] The waterproof effect of mixed concrete in underground engineering is one of the important quality indicators to measure underground engineering. It is directly related to the corrosion and aging of underground engineering equipment and structures, and affects the operating environment and service life of underground engineering. However, due to concrete construction quality defects, waterproof structure design defects and other reasons, it has become normal to see different degrees of water leakage in underground engineering concrete. [0003] In the prior art, cement grout or chemical grout grouting is mainly used for the treatment of leaking water from concrete structural defects, and the traditional drilling and caulking...
