<p>PURPOSE: To carry a squeeze-off tool easily by making it possible to break up into three parts with a light weight, a pressurizing part, a bracket, and a receiver part, in a squeeze-off tool to stop the flow of a clean water, a sewage water, and the like, by compressing a pipe in order to replace the pipe or to connect a branch pipe, in an existing piping of a water supply, a drainage, and the like. CONSTITUTION: When a squeeze-off of a plastic pipe 23 in an excavated ditch is carried out, a receiver C is lowered to the excavated ditch in the condition to lay down one side side arm 18, and a receiver bar 16 is placed to the lower side of the plastic pipe 23 together with the laid down side arm 18. Then, a bracket B is carried on the side arm 18 laid down, and connected on the upper end of both side arms 18 by inserting its connecting pins 21 to the installing parts 11a. Then, a pressurizing part A is carried by grasping its handle 8, and the fixing plate 2 of the pressurizing part A is installed in a cylinder bracket 11 in the condition opening the presser metals 13. After that, a pressure oil is delivered to hydraulic cylinders 3 from hydraulic apparatuses, so as to lower the pressurizing bar 5, and the plastic pipe 23 is compressed between the receiver bar 16.</p> |
