Construction process for plugging and consolidating concrete crack through chemical grouting

Abstract

The invention relates to a construction process for plugging and consolidating a concrete crack through chemical grouting, which belongs to the technical field of concrete consolidation engineering and in particular relates to a concrete crack plugging and consolidating method. The construction process for plugging and consolidating the concrete crack through the chemical grouting comprises the following steps of the first step, opening a V-shaped groove, which is 20 mm wide at the upper part and at least 20mm deep, along the concrete crack; the second step, flushing the V-shaped groove; the third step, plugging the V-shaped groove; the fourth step, drilling a grouting hole; the fifth step, mounting a grouting head; the sixth step, performing grouting; and the seventh step, removing the grouting head. The construction process for plugging and consolidating the concrete crack through the chemical grouting, provided by the invention, is advantaged in that the grouting process is simple and convenient, the operation of the process is convenient, the crack is closely plugged without a gap, the plugged concrete crack is durable and fatigue-proof and not prone to crack again, the concrete crack plugging effect is good, the concrete surface is completely dry, leakage and moist are avoided, the thickness of a plugging and finishing coating on the surface of the crack is uniform, no missed brushing, no base exposure, no peeling, no swelling and no crack are achieved. And moreover, the process causes no pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of concrete reinforcement engineering, and in particular relates to a plugging and reinforcement method for concrete cracks. Background technique [0002] At present, concrete is widely used in various engineering constructions, especially in bridge construction, engineering foundation, road hardening and other fields. While bringing convenience to the construction, due to some factors such as construction quality and natural external forces, it is easy to cause cracks in the concrete, and water seeps into the cracks, which not only greatly reduces the strength and function of the concrete, but also causes irresistible damage to the concrete due to long-term continuous water seepage. If the concrete cracks are not blocked and reinforced in time and allowed to develop, dangers will easily occur and irreparable losses will be caused to engineering safety, personal and property safety. [0003] The current tre...

While bringing convenience to the construction, due to some factors such as construction quality and natural external forces, it is easy to cause cracks in the concrete, and water seeps into the cracks, which not only greatly reduces the strength and function of the concrete, but also causes irresistible damage to the concrete due to long-term continuous water seepage. If the concrete cracks are not blocked and reinforced in time and allowed to develop, dangers will easily occur and irreparable losses will be caused to project safety, personal and property safety

[0003] The current treatment methods for concrete cracks on the market are basically plugging, which only seals the cracks on the surface, but it does not have any real effect on the reinforcement of concrete, and the sealing method is simple in process, and the effect is not good. crack again
