A grouting pipe for minimally invasive grouting repair as shown in fig. 1-4, the grouting pipe comprising:
a protection tube 1, wherein a communicated slurry channel is arranged in the protection tube 1, and as shown in fig. 2, the protection tube 1 comprises a tube cap 11, a fixing part 12 and a tube body 13 which are connected in sequence; the pipe cap 11 is used for connecting with a spray gun and is used as an inlet of slurry, and the fixing part 12 is used for fixing the spray gun; the pipe body 13 is conical, the diameter of the pipe body is gradually reduced towards the bottom of the pipe body 13, and the outer wall of the pipe body 13 is attached to the inner wall of the grouting hole;
and the drainage tube 2 is connected with the bottom of the tube body 13 of the protection tube 1, the drainage tube 2 is made of metal, and the drainage tube 2 is used for guiding the slurry to the bottom of the crack. As shown in fig. 3, the crack in the figure is a structural schematic diagram of a reflection crack of a road base, in the repairing process, a hole is drilled to a base where the crack is located, then a drainage tube 2 with a required length is fixed on a protection tube 1, a spray gun of a guniting mechanism is connected to a tube cap 11 of the protection rod, grout is transmitted to the crack of the base through the protection tube 1 and the drainage tube 2, and the crack is filled with the grout under the action of pressure, so that the crack is repaired. Here, the length of the drainage tube 2 is generally set to be half of the thickness of the upper layer of the base layer so as to dispose the hidden trouble of the periphery of the crack.
Here, as shown in fig. 4, since the pipe body 13 is in a tapered structure, the outer wall thereof is in full contact with the grouting hole, so that the gap between the grouting hole and the protection pipe is less, and no pressure leaks from the grouting port under the compression of the tapered structure, thereby improving the sealing performance during construction; in addition, the diameter of the contact part of the conical structure and the grouting hole is larger than that of the drainage tube 2, so that the drainage tube 2 is in a suspended state, the contact between the drainage tube 2 and the grouting hole is reduced, and the possibility that the drainage tube is damaged is reduced. In addition the utility model discloses a drainage tube 2 adopts metallic structure, and is preferred, for stainless steel construction, has further reduced drainage tube 2 and has received the possibility of damage, also prevents to lead to the rusty possibility of drainage tube 2 because of weing.
