Pipe Cleaning

High Pressured Water Jetting with Vacuum

Applus+ Velosi cleaning trucks are a combined high pressure water jetter with

vacuum. The jetter will remove all debris including sand, silt, roots, scale and

grease from inside the pipelines. The vacuum will lift all these debris from the

manholes into the waste tank.

Adjustable water pressures and cleaning nozzles can be used that will be suitable

for all pipes.

6 Pipeline Rehabilitation

CCTVApplus+ Velosi has a number of camera systems which range from 80 mm to 1600 mm

pipe diameters.

CCTV surveys determine the condition of the inside of the pipe, we also offer the

following:

1. Pipe deflection (Ovality)

2. Internal pipe measurements

3. Lateral pipe connection measurements

4. Tilt surveys

5. Joint gap measurements

All reports are coded to EN 13508 standard.

Our operators and reporters are certified to MSCC4 (WRC).

8 Pipeline Rehabilitation

CIPP/GRP Lining

Glass Reinforced Pipe, UV Technology

A cured-in-place pipe (CIPP) is one of several trenchless rehabilitation methods

used to repair existing pipelines. CIPP is a jointless, seamless, pipe-within-a-pipe

with the capability to rehabilitate pipes ranging in diameter from DN 100 to DN

1600. The process is carried out through the manholes, avoiding excavation and

traffic congestion.

There are several different materials and methods of curing, Applus+ Velosi are

lining with glass reinforced liners which are cured using UV technology. The majority

of pipes being rehabilitated using CIPP are sewer and drainage, these lines will have

internal failings and infiltration problems. Once lined these pipes will be good for

another 50 years.

10 Pipeline Rehabilitation

Patch Repair

Localized Structural CIPP Repair

The patch repair system provides a localized repair within an existing pipeline. It

is quick to install and offers little disruption to property, services and traffic.

The patch is installed through the manhole avoiding any excavation and

replacement costs.

Pipeline RobotsApplus+ Velosi has several robots that were designed for rehabilitation works

inside sewer pipes ranging from DN 100 to DN 1000.

Various tool attachments permit the sewer robot to perform milling, grinding,

filling and injection operations. Mainly obstacles such as misplaced pipe

connections, roots, encrustations, concrete blockages and deposits, as well as

opening laterals after patch repair and CIPP lining.

Manhole Inspection and RehabilitationManholes are becoming increasingly in need of repairs due to infiltration and traffic pounding.

Once the manhole inspection has been carried out a rehabilitation method can be chosen.

The choices are as follows:

1. Cured-in-Place Liners

2. Cementitious Coatings/Grouts

3. Polymer Modified Coatings

Pipe Bursting Pipe bursting and pipe splitting are trenchless methods used to replace existing pipelines in the

same alignment without physically removing the existing pipeline. Bursting and splitting by using

the existing alignment to replace a pipe avoids the need to secure additional right-of-way to

install the replacement pipe. Bursting and splitting can be used to upsize the pipeline, increasing

its flow capacity.

Pipe bursting was initially developed in the 1980s to replace small diameter cast iron gas

distribution lines, but has since grown in acceptance as an effective method for replacing

pipelines diverse in size, material type, and functions.

Pipe bursting is used to replace all pipes such as clay, concrete, steel and cast iron through the

application of a static or pneumatic bursting head to fragment the existing pipe. Simultaneously,

a new product pipe attached to the back of the bursting head is installed in the same alignment

as the original pipe.

Close Fit LiningClose fit lining is a term used to describe a range of techniques for renovating

pipelines, in which the cross section of the liner is temporarily deformed

before insertion into the carrier pipe. The liner is subsequently restored close

to its original diameter, forming a close fit with the original pipe.

The liner is deformed by either reducing its diameter or changing its shape. To

do this the liner can either be passed through tapered dies, through rollers or

be folded, either on site or in the factory. After insertion into the carrier pipe

the liner is reverted, either by natural relaxation or through the application of

steam or water under pressure. Each close fit lining system uses a different

combination of deformation and reversion methods.

The different types of close fit lining systems that are currently available are:

• Deformed Pipe

• Die drawing

• Rolldown
