EN - Case Study Picote Mini Multi-Cutter in Saxony Germany

In a nutshell

Muffenversatz vorher

Nine metres of DN125 clay pipe. Four displaced joints, two bends and a lateral connection sealed by a glass fibre liner.

Five hours later, the kitchen connection was open again and the pipe was ready for the next stage of rehabilitation.

Background

A house connection running between two inspection chambers on private property was due to be rehabilitated using glass fibre patch liners.

Before work could begin, the team had several problems to address. Four pipe joints had shifted, and an earlier attempt at a patch repair had accidentally sealed off the DN100 kitchen connection.

The Challenge

For the homeowner and the contractor, it was a nightmare scenario. The kitchen connection had been sealed during a previous repair, and the pipe was still not ready for the next stage of work.

In just nine metres, the team faced several obstacles, each placing different demands on the cutting equipment.

Two 45° bends came right at the start of the pipe. Beyond them, four displaced joints in the DN125 clay pipe had to be ground back, and the sealed kitchen lateral had to be reopened.

Reaching these points was only half the challenge. The team also had to cut precisely once they got there.

The team at DSE Saugentsorgung Nebra GmbH used the Picote Mini Multi-Cutter system with a Mini Miller +C HD, Picote Push Rods, and Easy-Cut and diamond cutting heads.

The team ground back the four displaced joints in preparation for the planned glass fibre patch repairs.
They reopened the kitchen connection that had been accidentally sealed.
The work also included high-pressure jetting and a final CCTV inspection, including a leak test.

The Picote Solution

The Mini Multi-Cutter is often compared with robotic cutting systems. This job shows what a compact system can do when the same pipe calls for very different cutting capabilities.

Grinding back four displaced joints in hard clay took power.
Getting through two 45° bends took exceptional flexibility.
The team also had to remove the liner, a task that can be a nightmare for any rehabilitation contractor. Reopening the sealed kitchen connection then called for a high degree of precision. The Mini Multi-Cutter handled all these demands in a single five-hour job.

Set-up on site also mattered. The crew already carried a Mini Miller in their vehicle, and the compact cutter and push rods were easy to take to the access point. That gave the crew the cutting power they needed with a simple set-up on site.

Two operators completed the work between 8 am and 1 pm. After five hours, the kitchen connection was open again and the clay pipe was ready for the planned patch lining. The crew estimated that they saved several days compared with conventional methods.

Feedback from the Site

„It works really well! We were really surprised by how easy the cutter was to handle and how much power it had. One big advantage is definitely how easy it is to set up on site.”
