1 Introduction

2 Construction and Requirements

2.1 Requirements Bridge and Tunnel drainage pipelines must be resistant to external influences (spreading salts and acidic exhaust gases). vibrations and high temperature fluctuations. In addition. they need to be stable in form. easy to install. robust and of a long service life.

LU

Bridges and Tunnels are an essential but sensible part of every street network.

TI

O N

PD

F

The most common damage to bridges is caused quite often by non effective. defect or wrongly installed drainage systems. Another cause might be in the wrong material choice for the individual components of the drainage system.

They allow best possible routing by crossing mountains. valleys and rivers. But their open construction makes them vulnerable for damages and corrosion.

O

Only adequate structural measures help to prevent major damages and corrosion. Bridge and Tunnel dewatering is one of these measures. The installation and functionality of an appropriate dewatering system is often crucial for the durability of bridges and tunnels. Providing sage water drainage. effective dewatering systems guarantee safe driving as well as corrosion prevention. even at extreme weather conditions.

ES

They should not impair the harmonious appearance of the constructions and are therefore usually adapted to the construction. Coloured designs with a long life-cycle are standard for this kind of application.

R

2.2 Construction of a bridge drainage system

LO

W

A complete. functional drainage system consists of: •

the inlet system (“bridge outlet“)

•

the pipeline system with mountings and fixings and

•

the drainage system

The water drained from the bridge is fed into a draw pit and ed on into a storage reservoir.

2.3 Bridge Dewatering Systems

PD

F

The dewatering pipeline should be installed with a minimum decline of 2 %. The pipeline´s diameter is dependent on the rainfall intensity. Bridge drainage systems should always take a ten-year peak rainfall

TI

O N

are able absorb movements. Especially in this area. the connectors between the different parts of the pipeline system must be tightly ed. These areas should be checked in line with the periodic inspection and. if necessary. immediately tightened.

value into consideration. The pipeline system consists of various pipes and fittings. which guarantee the safe transport of the drainage from the bridge outlet to the outflow area. either into a reservoir or into the ground. Various fixings are used for mounting the drainage pipelines. whereby a more flexible modular system is advantageous.

2.4 Tunnel Drainage Systems

LU

A laminated dewatering system made of FLOWTITE GRP pipes is also first choice for tunnelling drainage. The systems are usually executed acc. to local regulations. in for example acc. to ZTV-ING. part 5 “Tunnel construction” (see below).

R

ES

O

The mounting system should fit without problem and free of tension to the camber and pitch of a bridge. In this way unforeseen deformations. and therefore water escapes. can be avoided. The fixing elements will be arranged according to static requirements and its distance is usually between 2 m and 3 m. In a new construction. anchor rails should be set in the concrete; when renovating. plugs suitable for use in cracked concrete should be used. The pipeline system should be accessible and therefore able to be monitored.

LO

W

At the intersection from the bridge construction to the abutment. or between two bridges. flexible connection pieces must be attached to the pipeline system. They

3 FLOWTITE GRP Pipes

PD

F

The basic raw materials used in the FLOWTITE pipe´s manufacturing are resin. fibreglass and silica sand. FLOWTITE GRP pipes smaller than 300 mm are discontinuously manufactured with the same wall buildup than the bigger diameters. FLOWTITE pipes bigger than DN 300 are manufactured using the continuous advancing mandrel process. This process allows the use of continuous glass fibre reinforcements in the circumferential direction and creates a very dense laminate that maximizes the contribution from all three basic raw materials. Both continuous glass fibre rovings and choppable roving are incorporated for Roving rack high hoop strength and axial reinforcement. Saw

O N

FLOWTITE GRP pipeline systems are the perfect choice for the use in bridge and tunnel dewatering systems. Due to the raw materials used and the pipe wall build-up resulting in a multi-layer design. the use of these pipes guarantees long service life by being rust-free. as well as optimum safety through fast water drainage.

Finished pipe

With the FLOWTITE dual resin delivery system. the equipment has the capability of applying a special inner resin liner for severe corrosive applications while using a less costly resin for the structural and outer portion of the laminate. Taking advantage of the winding process. other materials such as veils or flame retardant additives can be added used to enhance the abrasion or fire resistance of the pipe. The pipes offer a high and consistent product quality worldwide and reliable product that complies to stringent performance standards such as AWWA. ASTM. DIN. EN. etc.

4 Product Advantages

High Chemical Resistance By choosing optimum resin. FLOWTITE GRP pipes can be used for almost all types of liquid. The ideal selection takes the chemical properties of the liquid and the operating temperature into consideration.

F

FLOWTITE Technology has been able to bring a product to the market that provides a low cost. longterm piping solution to customers around the world.

PD

The long list of features and benefits add up to provide the optimum installed and life cycle cost system and the unique combination of mechanical and chemical properties proves itself here in a special way.

Low Thermal Expansion The thermal expansion coefficient for FLOWTITE GRP pipes is approximately 24 – 30 x 10-6 1/K. Thermal expansion is therefore small and can be absorbed by couplings and ts.

O N

Superior Corrosion Resistance Thanks to its inherent corrosion resistance. the FLOWTITE pipe guarantees a long service life; in addition. the hard and smooth inner surface also offers no adhesion points for particles of any sort. This means that GRP pipes are practically maintenance free. In addition. they require no protective coatings or interior linings.

High Hydraulic Efficiency FLOWTITE GRP pipes offer a very smooth inner surface with low roughness and a flow coefficient of approximately C=150 according to Hazen Williams. In contrast to other. corroding pipe materials. the roughness of the interior surface of FLOWTITE pipes doesn’t change in the course of time. since GRP pipes are not susceptible to corrosion. This results in a high hydraulic efficiency. There are no particle deposits and there is no further abrasion resulting in extremely low surface resistance. This allows increasing the fluid level and the use of smaller diameter pipes.

Excellent UV Resistance There is no evidence that UV exposure is a factor that affects the long-term service life of FLOWTITE pipes. In their long and comprehensive experience in the Middle East in damp and desert conditions. in Scandinavia in various dark and cold winters. as well as in more than 30 years of above ground pipe laying. FLOWTITE has not found any indications of any structural effects of radiation on its GRP pipes.

Light Weight Due to the light weight of GRP pipes. they can be easily loaded and unloaded. without the need for heavy lifting equipment. It also allows the pipe nesting that reduces transport costs and allows quicker installation.

LO

W

R

No E – Potential GRP pipes are made of a non-metallic material resulting in a lack of electrochemical corrosion. Stray currents from train lines or overhead cables do not attack the pipes.

Individual design and colouring Although the pipes are UV resistant. a coloured outer surface that fits to the overall bridge design is quite often requested. The material properties of GRP allow the individual colouring of the outer layer acc. to the tailormade request of the customer

PD

F

Good Fire resistance (optional) Upon request. a special resin with an aluminium hydroxide additive will be used. This resin. designed acc. to German ZTV-Ing specification. has flame-retardant properties. Inflowing burning liquid poses no threat to the statics of the pipes.

Easy installation For pipes with a diameter bigger than DN 300. the production process allows the manufacture of individual lengths up to 18 metres. This results in a reduced number of couplings and shorter installation time. The light weight and easy handling of FLOWTITE pipes enables a fast installation and the precise inner and outer pipe dimensions allow the use of standard pipe mounting constructions with standard fixing systems. The material properties make a time consuming. additional special protective coating unnecessary.

LO

W

Low maintenance costs The very smooth inner lining and a high mechanical resistance prevents sludge build-up and provide consistently high flow rates. The excellent chemical resistance e.g. against thawing agents. oil residues. abrasive or brake dusts and the fact that the pipes are electrically non-conductive and non corrosive. make FLOWTTE GRP pipes very economical and long-lasting with low maintenance efforts over the years.

O N

Longitudinal Pipelines The pipes of longitudinal drainage pipelines are connected with steel couplings or FLOWTITE GRP standard couplings. The pipe mountings must be fixed

Downpipes and Abutments All longitudinal pipelines lead to abutments and are then fed through or diverted. In order to compensate lateral and axial movement between the bridge and the abutment. bridge drainage hoses will be installed.

to the existing anchor rails beforehand at intervals according to static requirements. During renovations. the mounting is performed using special plugs approved for use in cracked concrete. The pipes are then laid in the lower half of the pipe clamp and then fixed with the top half. Branch saddle pieces are fixed at the points where lateral pipes . Cleaning saddle pieces are installed in flow direction after each branch. or after at least 30 m. For installation. the longitudinal pipe will then cut at the necessary point. The use of saddle pieces means that no waste is produced. In addition. the anchor rails can be set in the concrete in advance without problem.

The flexible pipe connector also makes up possible building inaccuracies between the incoming and outgoing pipes.

Connection to Bridge Outlets The sinks on the bridge surface are connected the longitudinal pipelines by using special connectors.

Chamber Connections • Draw Pits The pipelines are connected to chambers behind the abutments or at the base of the abutments. • Collection Chambers The collected surface water is fed into collection chambers or the receiving waters.
