Under the assistance of a nondestructive detection technology, the depth and the size scale of the hidden danger can be detected, and conditions are created to timely process and repair the hidden danger based on a specific engineering background.
The common treatment methods include two methods, namely splitting the structure for re-grouting, and performing high-pressure grouting filling by using a grouting hole. But for concrete structures with higher compactness, such as piers, bases and the like, or reinforced concrete prefabricated components, such as box girders, duct pieces, high-speed rail plate structures and the like, the internal porosity of the concrete is small, and the communication pore path is short; the grouting is unrealistic through dissection, because the space shape of the hidden danger needing grouting is often not regular, the grouting hole is used for grouting, a grout channel is easily blocked by grout, and the ideal effect is difficult to achieve by the dead weight of the grout or high-pressure grouting.
According to the glass fiber reinforced plastic vacuum resin injection molding process, if the space with hidden danger in the structure to be grouted can be sucked, the grouting operation of hidden danger in the concrete inner structure can be completed in a self-suction mode by means of the air pressure difference between the grouting liquid level and the inner part of the vacuum structure to be grouted without pressurization of a grouting pump and controlling the flow of grout, and the grouting process is simple and convenient in grouting construction and good in grouting effect.
The invention patent CN 110821205A discloses a negative pressure repairing construction device for concrete cracks, which is characterized in that: the grouting base is composed of a base body and an injection port, wherein the middle part of the base body is vertical to the base body and penetrates through the base body; the negative pressure pumping device comprises a negative pressure pumping top nozzle inserted into an injection port of the grouting base and an air pipe, one end of the air pipe is connected with the negative pressure pumping top nozzle, and the other end of the air pipe is connected with the vacuum pump; the grouting device comprises a grouting nozzle inserted into the filling opening of the grouting base and a grouting pump connected with the grouting nozzle through a grouting pipe. The construction method comprises the following steps: 1) determining the position of the base: arranging a negative pressure pumping port or a grouting port at a distance of 30-50 cm; 2) sealing concrete cracks: sealing the concrete cracks with a high-strength sealing material, and reserving the position of a base; 3) and a base is installed: fixing the base along the crack at the selected positions of the negative pressure pumping port and the grouting port; 4) and injecting a repairing agent: under the closed condition, respectively inserting a negative pressure pumping top nozzle and a grouting nozzle into the injection ports of two adjacent bases, starting a vacuum pump, and pumping air in the crack out through the negative pressure pumping top nozzle and an air pipe to generate negative pressure; and starting the special grouting pump, filling the prepared repairing agent into the concrete crack under the combined action of extrusion of the grouting pump and negative pressure in the crack, stopping grouting after the filling opening of the negative pressure top nozzle base is pumped and the crack is confirmed to be filled, and moving the negative pressure top nozzle and the grouting nozzle to the filling opening of the next group of bases for circular grouting.
Although the comparison file also utilizes the negative pressure to carry out grouting assistance, the comparison file aims at surface cracks, needs two mouths, sets up according to 30 ~ 50cm distance and takes out negative pressure mouth or slip casting mouth ", through surface inside slip casting, needs the slip casting pump, can not solve inside local segregation, bubble or the potential hazard of coming to nothing of concrete structure.
