Seismic retrofitting method for existing manholes

Seismic retrofitting method for existing manholes

A method for seismic retrofitting the connection between existing manholes and pipes using non-excavation techniques.

This construction method involves cutting the walls of the manhole along the outer circumference of the pipe using a specialized cutting machine, thereby separating the edges of the manhole and the pipe. The cut grooves are filled with backup materials to prevent the inflow of soil and sealing materials to prevent the inflow of groundwater, enhancing the seismic resistance of the connection. Additionally, by installing absorption rubber blocks in the invert section, it prevents the pipe from protruding into the manhole during an earthquake, thereby avoiding damage to the pipe opening. 【Features】 - Manhole covers can be constructed with an internal diameter of 600mm or more. - Construction is possible for pipe internal diameters up to 700mm. - Seismic performance can accommodate a maximum bending angle of 5.0 degrees and displacements of up to 100mm due to level 2 seismic motion, ensuring the functionality of wastewater flow. - Minimal impact on surrounding ground, underground installations, local residents' lives, and traffic. *For more details, please download the PDF or feel free to contact us.

Seismic reinforcement method "Seismic One-Shot (Medium Diameter)"

Seismic reinforcement method "Seismic One-Shot (Medium Diameter)"

Ensuring seismic performance by rehabilitating aging pipes! There is no risk of damaging nearby buried objects.

The "Seismic One-Shot-kun (Medium Diameter)" is a non-excavation seismic reinforcement method developed to add seismic performance against level 2 seismic motions by modifying the manhole connection part to a flexible structure before rehabilitation. The construction involves using a specialized cutting machine to cut and remove the existing pipes within the thickness of the manhole wall without penetrating into the surrounding ground. A stainless steel collar is then bonded and fixed in place, and two layers of seismic rubber rings with elasticity and water-tightness are installed. Elastic wet epoxy resin is filled into the gap between the manhole wall and the seismic rubber rings to secure them. After applying this method to the upstream and downstream manhole connection parts, the construction of the rehabilitation pipe allows for the seismic reinforcement of both the rehabilitation pipe and the manhole connection part. 【Features】 ■ Applicable pipe diameters are from an inner diameter of 450mm to less than 800mm, with a manhole depth of up to 10m. ■ Addresses bending, extraction, and protrusion of pipes due to level 2 seismic motions. ■ Does not affect the performance (nominal diameter, strength, elasticity, etc.) of the rehabilitation pipe. ■ The specialized cutting machine can only cut and remove the existing pipes within the thickness of the manhole wall. ■ Since it does not penetrate into the surrounding ground, there is no risk of damaging nearby buried objects. *For more details, please refer to the PDF document or feel free to contact us.

Pipe rehabilitation method "Alpha Liner H Method"

Pipe rehabilitation method "Alpha Liner H Method"

Self-supporting pipes up to a diameter of 900mm are possible! A pipe rehabilitation method that has a longer material storage period and achieves further thin-walling.

The "Alpha Liner H Method" involves pulling the Alpha Liner H into an existing pipe, expanding it using air pressure to make it adhere closely to the inner surface of the existing pipe, and then irradiating it sequentially with light of a specific wavelength from the pipe opening to cure the resin. By improving the materials used in the conventional Alpha Liner, the long-term bending elastic modulus has been increased from 9,500 N/mm² to 12,000 N/mm², achieving even higher strength. Additionally, with the improvement in long-term bending elastic modulus, the material of the Alpha Liner becomes thinner. Moreover, it inherits the characteristics of the conventional Alpha Liner, allowing for shape confirmation before curing, construction that is not affected by environmental temperature, and minimizing traffic restrictions, noise control, and CO2 emissions during construction. 【Features】 - Not affected by environmental temperature - High strength (long-term bending elastic modulus: 12,000 N/mm²) - Shape confirmation can be done before curing - Capable of manufacturing materials over 100m - Short construction time *For more details, please refer to the PDF document or feel free to contact us.
