<p>PROBLEM TO BE SOLVED: To provide a pipe branching valve device and its branching method for horizontally connecting a branch pipe to a main pipe for flowing fluid, and burying the main pipe and the branch pipe in the same depth. SOLUTION: This pipe branching device branches the main pipe 10 for flowing the fluid and has a hollow body part 100, a cutoff groove 110 arranged in the body part 100 and communicated with the inside so that a cutoff plate is inserted, and a saddling part 120 integrally formed with one side opening part of the body part 100, and fused on an outer peripheral surface of the main pipe 10 to easily perform connecting work of the main pipe and the branch pipe, and the main pipe and the branch pipe can be buried in the same depth.</p> |
