Description

Technical Field

[0001] The present application relates to the field of grouting pipes, and in particular to a multifunctional grouting pipe for exterior wall repair. Background Art

[0002] At present, many external wall insulation systems adopt insulation board systems and are constructed using a thin plastering process. This construction process relies on polymer mortar to bond the insulation board and the base wall, and the bonding area ratio is generally around 40%-60%. In actual use, because the bonding area in the above ratio does not take into account the flatness of the base wall, if the flatness of the base wall is poor, the size of the cavity between the insulation board and the base wall, that is, the area and depth will exceed the conventional requirements, which will further lead to a reduction in the local bonding area of ​​the insulation board.

[0003] The traditional external insulation repair process is to completely remove the insulation board. The grouting pipes in the existing technology are mostly made of steel pipes. The surface of the grouting pipes is relatively smooth, and the pipe mouths are easy to fall off, affecting the quality of grouting. In addition, the humidity of the slurry used in the traditional exterior wall repair process may not be enough, which may cause secondary damage to the wall during the repair, or even irreversible damage.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0008] Preferably, a spring is fixedly connected to one side of the outer wall of the connecting pipe corresponding to the spring groove, and the springs are connected to the spring groove.

[0009] Preferably, a connecting shaft is rotatably connected to one side of the interior of the connecting pipe, and the connecting shaft extends to the interior of the second pipe.

[0010] Preferably, a motor is fixedly connected to one side of the interior of the second pipe, and a driving end of the motor is fixedly connected to one side of the connecting shaft.

[0011] Preferably, an anti-blocking pipe is fixedly connected to one side of the outer wall of the first pipe, and a grouting port is opened on one side of the upper surface of the first pipe.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. A plurality of fixed blades are installed between the first pipe and the second pipe through a plurality of rotating shafts, and are connected to the spring through the spring groove opened on the inner wall of the fixed blade.
