The invention discloses an existing building outer wall in-situ reinforcing and repairing method, belongs to the technical field of existing building outer wall repairing, and aims to overcome the defect that an existing existing building outer wall in-situ repairing method is poor in anchoring effect. According to the fixing pin with the knocking expansion and grouting functions, connection between the fixing pin and a wall is tighter and firmer through outward expansion of the bent portion of the expansion pipe and grouting operation, the tensile bearing capacity standard value of the fixing pin with the knocking expansion and grouting functions is effectively increased through the reinforcing fixing structure at the inner end, and the problem that the tensile bearing capacity standard value is low in the prior art is solved.

The utility model discloses a kind of driving device for pipeline detection, it is related to pipeline detection technical field, including connecting disc, the surface of connecting disc is provided with power mechanism, the power mechanism includes the fixed cover fixedly connected with connecting disc, the middle part of the fixed cover is rotatably connected with transmission gear, the middle part of transmission gear is connected with support mechanism, this driving device for pipeline detection, by bolt, connecting disc is fixedly installed in pipeline detection tail part, by pressure pipe, support rod is provided with pulling force, make power wheel and pipeline inner wall closely resist and touch, rotate by first sprocket control power wheel, power wheel and pipeline inner wall friction generates thrust, drive pipeline detection device to move forward, when meeting elbow, by transmission gear control support plate rotation, make support rod drive fixed shell rotation, adjust the position of power wheel and pipeline resist and touch, make power wheel and elbow outermost circle inner wall resist and touch, improve the stability of driving detection device movement.

The utility model relates to the technical field of hose joints, in particular to a non-leakage hose joint for connecting different pipe diameters, which comprises a first butt joint, the first butt joint is connected with a second butt joint through a fixing structure, the first butt joint is rotatably connected with a rotating ring, the rotating ring is fixedly connected with four buckles, and the first butt joint is connected with the second butt joint. Four protruding blocks are fixedly connected to the second butt joint, the buckles abut against the protruding blocks, the first butt joint abuts against the second butt joint, the two ends of each protruding block are of an inclined face structure, a groove is formed in the first butt joint, a second sealing ring is installed on the second butt joint, and the second sealing ring is clamped with the groove. A first hose is mounted on the first butt joint through one mounting structure, a second hose is mounted on the second butt joint through the other mounting structure, and the pipe diameter of the first hose is larger than that of the second hose; the water pipe can be prevented from being twisted and deformed due to the fact that the connectors drive the water pipe to rotate, so that smoothness of water flow is guaranteed, and stability of connection of the two connectors is enhanced.
