Description

  The present invention relates to a siphon drainage system unit used in a siphon drainage system that drains water using siphon force, and a construction method of a siphon drainage system using the siphon drainage system unit.

  In recent years, siphon drainage systems have been proposed in place of conventional gradient drainage systems. As described in Patent Documents 1 and 2, the siphon drainage system is configured to include a watering device and a siphon drainage pipe, and the siphon drainage pipe is a horizontal pulling pipe that is non-sloped along the floor slab. It is comprised with the pipe and the soot pipe which makes a hanging part. And in the siphon drainage system, the drainage efficiency from the watering device is improved by utilizing the siphon force (negative pressure) generated in the soot pipe.

  In the siphon drainage system, the drainage discharged from the watering device flows into the siphon drainage pipe and fills the horizontal pulling pipe forming the horizontal part of the siphon drainage pipe and the dredging pipe forming the hanging part of the siphon drainage pipe. When the dredging pipe of the siphon drainage pipe is filled with drainage, the drainage in the dredging pipe falls due to gravity, and a suction force corresponding to the head difference in the dredging pipe, that is, siphon force is generated. Wastewater is sucked down and flows down.

  By the way, in the case of conventional gradient drainage, in a barrier-free unit bath, if the floor height of the entire floor is to be set as low as possible, if the floor is low, the housing of the part where the watering device is installed It was necessary to add a gradient to the drain pipe. Therefore, even when renovation is performed, the movement of the watering device has to be installed in the existing installation.

  On the other hand, in the above siphon drainage system, the horizontal pipe is piped along the floor slab without any gradient, so there is no need to drop the casing and make a gradient like conventional gradient drainage. There is an advantage that the degree of freedom of movement is high.
