Abstract
A pipe clamping tool (10) includes a pair of fixing members (11) that are each fixed to a side wall of an ground space and are arranged opposite to each other to clamp a pipe, and a covering material (12) mounted between the pair of fixing members (11) and the pipe and covering an outer periphery of the pipe.
Claims15
A pipe clamping tool configured to suppress buckling of a pipe in an underground space, the pipe clamping tool comprising:
- a pair of fixing members, respective fixing members of the pair of fixing members being fixed to a side wall of the underground space and arranged opposite to each other to clamp the pipe, the pipe forcibly feeding gas, and the pipe traverses the underground space;
- and
- a covering material mounted between the pair of fixing members and the pipe, the covering material covering an outer periphery of the pipe, and thereby a combination of the pair of fixing members and the covering material suppressing buckling of the pipe caused by a pressure of the forcibly fed gas inside the pipe.
A method for clamping a pipe, comprising:
- covering, by a covering material, an outer periphery of the pipe, the pipe forcibly feeding gas, and the pipe traverses an underground space;
- clamping the covered pipe with a pair of fixing members from both sides of the covered pipe;
- fixing each of the pair of fixing members to a side wall of the underground space, and thereby a combination of the pair of fixing members and the covering material suppressing buckling of the pipe caused by a pressure of the forcibly fed gas inside the pipe;
- determining a pressure of the forcibly fed gas inside the pipe in a consumption-side tank that is measured by a pressure gauge as being equal to or higher than a threshold;
- and
- determining, based the determined pressure of the forcibly fed gas and the threshold, buckling of the pipe has occurred.
