Description of the Related Art A head provided at the tip of a conventional high-pressure hose used for cleaning piping equipment is provided with an injection hole along a circumferential direction for injecting high-pressure water radially obliquely backward with respect to the traveling direction. A plurality of nozzles perforated at a predetermined pitch, and a free guide connected to the tip of the nozzle.

As disclosed in JP-A-5-120380 and JP-B-49-37403, the high-pressure hose is provided with rotation by rotating the rotary drum.

内周面の洗浄を行っている。On the other hand, as shown in Japanese Patent Application Laid-Open No. 54-110658, a nozzle connected to the above-mentioned high-pressure hose tip has a propulsive force by high-pressure water injected from the nozzle and a rotating drum. With the operation of pulling out the high-pressure hose, the inside of the drainage pipe rotates and advances, thereby cleaning the inner peripheral surface of the pipe.

高圧ホースを回転させ、これにより該高圧ホース先端に
連結したノズルを回転させると、ノズルは縦管の内周面
に沿って旋回する。The drain pipes to be cleaned are roughly divided into a vertical pipe and a horizontal pipe. According to the conventional drain pipe cleaning apparatus described above, a high-pressure hose is rotated inside the vertical pipe. When the nozzle connected to the tip of the high-pressure hose is rotated, the nozzle turns along the inner peripheral surface of the vertical pipe.

しづつ引き出して縦管内に送り込むと、ノズルは縦管内
周面に沿って螺旋状に旋回しつつ前進し、縦管の内周面
に付着した固形物をノズルから噴射された高圧水により
粉砕除去する。In this state, when the high-pressure hose is gradually pulled out from the rotary drum and fed into the vertical pipe, the nozzle advances while spirally turning along the inner peripheral surface of the vertical pipe, and the solid adhered to the inner peripheral surface of the vertical pipe. The material is pulverized and removed by high-pressure water sprayed from a nozzle.
【０００７】一方、排水管が横管の場合には、横管内で

重が作用するので管内周面に沿って旋回することはな
い。On the other hand, when the drainage pipe is a horizontal pipe, even if the high-pressure hose is rotated in the horizontal pipe, the nozzle is turned toward the bottom of the pipe by its own weight. There is no.

少しづつ引き出して管内に送り込んでも、ノズルは横管
の管底に沿って単に直線的に進行するだけで、横管内周
面に沿って螺旋状に旋回することはなく、横管内周面の
うち特に横管上部の洗浄力が劣る難点がある。Therefore, even if the high-pressure hose is rotated in the horizontal pipe when the drain pipe is a horizontal pipe, and the high-pressure hose is pulled out from the rotary drum little by little and fed into the pipe, the nozzle simply extends along the pipe bottom of the horizontal pipe. However, there is a drawback that the cleaning power of the horizontal pipe inner peripheral surface, especially the upper part of the horizontal pipe, is inferior.

均一に洗浄することができなかった。Further, since the injection pressure of the high-pressure water injected from the injection hole of the nozzle decreases as the distance from the pipe wall increases, solid matter adhering to the upper portion of the horizontal pipe far from the pipe bottom is pulverized by the high-pressure water. It is difficult to do this, and in order to pulverize it, equipment that supplies higher pressure and a larger amount of water is required, and in this regard, the conventional one cannot efficiently and uniformly wash the inside of the pipe. .

In the drain pipe cleaning method for cleaning, the nozzle is spirally swirled so that only a specific injection hole of the plurality of injection holes is always opposed to the inner circumferential surface of the pipe with the rotation and withdrawal of the high-pressure hose. At the same time, the diameter of the specific injection hole is set to be larger than the diameter of the other injection holes, and the angle α at which the central axis I of the specific injection hole intersects with the central axis H of the nozzle is defined as: Smaller than the angle which the center axis J with the center axis H of the nozzle intersects the injection holes beta (alpha <

The size of the diameter 0 is changed to the other injection holes 11, 12, 1 having the same diameter.
The diameter is set to be larger than the diameter of No. 3 so that a large flow of high-pressure water is injected from the injection hole 10.

ためである。The reason why the inclination angle α of the injection hole 10 having such a large diameter is set smaller than the inclination angle β of the other injection holes 11, 12 and 13 is as shown in FIG. In the drain pipe 5, the injection pressures F1, F of the high-pressure water injected obliquely rearward from the injection holes 10, 11, 12, 13 respectively.
2, F3, F4 (F1> F2 = F3 = F4), the component force F1 ′ of the injection pressure F1 acting on the inner peripheral surface 5a of the horizontal drain pipe 5 is set relatively small, and F2, F3, F4
Pressures F2 and F acting on the pipe inner peripheral surface 5a
This is because the respective component forces F2 ', F3', and F4 'of F3 and F4 are set relatively large, and only the injection holes 10 are pressed against the pipe inner peripheral surface 5a.
