Lateral reinstatement cutting is a technique used to remove the waste that gets built up on plumbing lines. It requires the pipes to be placed perpendicular or at an angle, and this creates stress which causes leaks in the system. This article will teach you how to use lateral reinstatement cutting and avoid these problems altogether.
Why Use Later Reinstatement Cutting?
Over time, underground pipelines are subjected to considerable wear and strain. They may be damaged by blockages, corrosion, shifting soil, or tree roots, in addition to the wear and tear of routine usage. Most pipes will need to be repaired or replaced at some point. Digging up the pipe was formerly the only option for such a job, which resulted in considerable damage to vegetation, roads, and sidewalks.
Fortunately, trenchless technology options for pipe replacement exist today, allowing homeowners to repair their broken sewage lines with minimum interruption and digging. Cured-in-place plumbing (CIPP) is an excellent solution for many municipal projects in terms of cost, effectiveness, and timeliness. A complex technology known as lateral reinstatement cutting is used in the last part of every municipal CIPP project. However, understanding it requires knowledge of the CIPP installation process.
What Is Lateral Reinstatement, And How Does It Work?
Lateral reinstatement cutters are used to create a new waterway in the side of a pipe. They are also called lateral cuts or diagonal cuts.
When CIPP is used to replace a municipal sewage line, the new pipe cures against the existing sewer pipe’s surface, thereby blocking the lateral connections that connect residences to the sewer system. Openings must be cut in the new pipe after it has cured to enable wastewater to flow from the house lateral lines into the sewer.
This was one of the most challenging and time-consuming tasks in any job in the early days of trenchless pipe repair. Pipe sections were often shorter, with pre-cut lateral lines, but lining technology progressed to the point where seamless pipe became much simpler to install. The first remote-controlled, robotic reinstatement cutters were on the market in the 1980s. The cable was labeled to show the position of each lateral aperture as these devices were snaked down the original pipe.
When it comes time to open up lateral lines in the freshly cured pipe, lateral reinstatement cutter equipment now includes sophisticated “pan and scan” CCTV cameras that enable plumbing specialists to see precisely where and what they’re cutting.
What Is Cured-in-Place Piping, And How Does It Work?
As a trenchless technological solution, CIPP effectively installs a brand new pipe within an existing pipe, with no joints or seams. It may be used on pipes that carry water, sewage, gas, or chemicals. A polyester tube that has been drenched in resin and dragged through the damaged pipe segment is used in this approach. The resin hardens after the new pipe is dragged through, causing it to fit securely against the previous piping, resulting in a brand new, seamless piece of pipe within.
Cutters For Lateral Reinstatement
Robotic cutters for lateral reinstatement are deployed by highly skilled operators to complete a trenchless pipe replacement project. These remote-operated, waterproof devices are inserted into new lengths of cured piping and moved to the rough position of the pre-existing laterals.
A CCTV camera is used to identify a slight bulge where the lateral opening is located, and the robotic cutter cuts a hole in the new pipe with a router bit. Once every lateral line is opened to allow wastewater to flow back into the line, the cutter is removed and then reinserted with a wire brush attachment to file down the polyurethane to fully open the lateral line.
The Bowman Dominator 430 is a 72-pound cutter that can cut pipes from 6 to 30 inches in diameter. It has a number of design advancements, including:
- A 2.5-horsepower geared air motor that cuts reinstatement time in half.
- Only eight moving parts, which allows for 30-minute disassembly & reassembly.
- A waterproof compartment with an isolated electric motor to prevent water damage and allow simple access.
- To save adjustment time, a quick-change head assembly with one adjustable gib is used.
- No external air tube, which gives the cutter an easy-to-operate & streamlined design.
Plumbers Also Provide Other Trenchless Technologies
In addition to lateral lining and reinstatement, plumbers may also offer sectional point repair, the reparation of a section of a broken pipe, pipe bursting, the act of breaking the original pipe as the new pipe slides through continuously, and manhole-to-manhole lining, which can completely rehabilitate deteriorating sewer lines in municipal sewage systems (manhole rehabilitation services using Sprayroq’s SprayWall structural polyurethane spray).
Trenchless pipe repairs can last half a lifetime, greatly increasing the service life of existing infrastructure.
