We will solve the problems of bends in sewer pipes, box culverts, and inspection openings!
● Base-mounted pipes and fume pipes are inexpensive materials compared to box culverts, but it is assumed that cast-in-place manholes or expensive precast rectangular manholes will be used for bends and inspection openings. The new structural manhole "Vent Joint Method" allows for handling bends and inspection openings with base-mounted pipes, which was not possible before. ● The new method "Vent Joint Method" enables construction at a much lower cost and with minimal space compared to conventional methods. ● The installation points with base-mounted pipes are endowed with seismic performance due to the TB method (seismic-resistant flexible joints), allowing for use in sewer channel construction. ● The "Vent Joint Method" is a patented method.

basic information
What is the BENT JOINT (New Structure Manhole) construction method! ● Curved sections and inspection openings can be installed simultaneously! ● All construction can be done with precast materials! - Improved workability! - Shortened construction period (no on-site pouring or demolding hassle) - Significant reduction in construction costs * * Compared to box culverts, the use of base pipes is economically advantageous, allowing for overall cost reductions. It is possible to insert pipes or box culverts vertically into the BOX. Due to the wider opening width, the size also increases, and since the pipes enter diagonally into square manholes, it becomes cumbersome to connect... The waterway's angle cannot ensure seismic performance with structures like wrapped concrete... The angle of the waterway can be accommodated with the diagonal cutting of the BENT JOINT! Therefore, the waterway can connect vertically to the manhole at any angle. By connecting vertically to the manhole, it is also possible to accommodate inflow and outflow pipes other than base pipes by adjusting the size of the BENT JOINT manhole! The angle can be adjusted up to the range that allows for diagonal cutting of the BENT JOINT manhole. * By combining BENT JOINT manholes, a 90° bend is also possible.
