FUNCTION AND STRUCTURE OF THE MANUAL

This product manual ensures that Geobrugg rockfall protection systems are manufactured without errors in ac-

cordance with the latest technical findings, that their area of application is clearly defined, that their functionality is

guaranteed, and that their installation is performed and checked properly.

The product manual is divided into the following parts:

•Proof of quality assurance

•System overview/rope guide

•Staking out

•Assembly details

•ISO 9001 certificate

This document does not claim to be exhaustive. Before starting an installation, it must be ensured that the copy of

the product manual is up-to-date. It is designed for general standard applications and does not take into account

any project-specific parameters. Geobrugg cannot be held liable for any additional costs which may arise in spe-

cial cases. If anything is unclear, please contact the manufacturer. Geobrugg AG's general terms and conditions

apply.

I RANGE OF APPLICATION

The design of rockfall protection systems is based on detailed investigations by specialized engineering firms,

particularly taking into account the following geotechnical aspects to define the range of possible applications:

•Previous Rockfall events

•Condition of the rockfall breakout zone

•Stability assessment of the entire rockfall zone

•Rockfall frequency

•Size of the blocks to be intercepted

•Trajectories and bounce heights of stones

•Calculation of kinetic energies

•Positioning of the barrier (considering the local topography)

•Anchorage conditions

II QUALITY OF THE SYSTEM COMPONENTS

Geobrugg AG, formerly the Geobrugg Schutzsysteme (Geobrugg Protection Systems) department of Fatzer AG,

Romanshorn, has been certified according to the quality management system requirements (ISO 9001:2008) un-

der the registration number CH-34372 since August 22nd, 1995. The certification center is the SQS (Swiss Asso-

ciation for Quality and Management Systems), which is a member of IQNet. The quality manual specifies in full

the way in which the individual system components (basic material, commercial products, and end products) are

checked extensively to eliminate poor quality. You can find the corresponding certificates in the appendix.

III FUNCTIONAL EFFICIENCY OF THE BARRIER SYSTEMS

The functional efficiency of the system is based on one-to-one rockfall tests, carried out and tested in accordance

with the guidelines for approval of rockfall protection nets ETAG 027 and the Swiss guideline of type approval of

rockfall barriers in Walenstadt, Switzerland (SG). The one-to-one rockfall tests are carried out by dropping a block

vertically into the middle field of a three-field barrier. The distance between posts is 10 m, and an impact velocity

of 25 m/s is reached. The full-scale tests were approved by a notified test body and the European Technical Ap-

proval (ETA) has the number ETA –13/0225 and the Swiss testing certificate of the federal office of environmen-

tal (BAFU) with the testing-No. S 13-1.

IV QUALITY CONTROL FOR INSTALLATION

This product manual describes in detail the different steps for installation of the barriers. These steps must be

faithfully followed by local contractors.

PRODUCT LIABILITY

Rockfall, landslides, debris flows or avalanches are sporadic and unpredictable. The cause is human (buildings,

etc.), for example, or forces beyond human control (weather, earthquakes, etc.). The multiplicity of factors that

may trigger such events means that guaranteeing the safety of persons and property is not an exact science.

However, the risks of injury and loss of property can be substantially reduced by appropriate calculations that ap-

ply good engineering practices, and by using predictable parameters along with the corresponding implementa-

tion of flawless protective measures in identified risk areas.

Monitoring and maintenance of such systems are an absolute requirement to ensure the desired safety level.

System safety can also be diminished through events, natural disasters, inadequate dimensioning or failure to

use standard components, systems and original parts, but also through corrosion (caused by environmental pollu-

tion or other man-made factors as well as other external influences).

In contrast to the one-to-one rockfall tests, which indeed test an extreme load case but still only demonstrate a

standardized situation, in the field the layout and design of a protection system can vary greatly because of the

topography. The influence of such alterations and adaptations cannot always be determined exactly. Critical

points are, for example, post spacing, changes in direction, placement angle of the rope anchor, and the direction

and velocity of impact.

Geobrugg can assist with estimating the influence of larger deviations and special situations, and can offer rec-

ommendations for feasible solutions. Geobrugg cannot, however, guarantee the same behavior as in the one-to-

one rockfall tests. In critical cases, it is advisable to reinforce particular components as compared with the stand-

ard barrier.

1HAZARD STATEMENT

QUALIFICATION OF THE GROUP LEADER

The management of installation may only be done by a qualified group leader.

CABLES WITH PRETENSION

Cables are under tension. During installation and pretensioning of the cables, make sure that there are no

persons in the danger zone.

RELEASING OF PARTS WITH PRETENSION

Releasing or cutting of components with pretension should be avoided. Should there still be necessary,

the utmost caution.

3. USING THE WIRE ROPE CLIPS

Instructions below apply to all wire rope clips according FF-C-450 type 1 class 1

(similar EN 13411-5 type 2) delivered by Geobrugg AG.

The distance ebetween the wire rope clips should be at least 1 x t but not exceed 2

x t , where tis the width of the clamping jaws. The loose rope end has to be 3 x e at

a minimum. Geobrugg recommends looping up the remaining free section and fixing

it directly behind the last wire rope clip on the tightened rope.

If you are using a thimble in the loop structure, the first wire rope clip must be at-

tached directly next to the thimble. For loops without a thimble the length hbetween

the first wire rope clip and the point of load incidence must minimally be 15-time the

nominal diameter of the rope. In unloaded condition the length hof the loop should

be not less than the double of the loop width h/2.

The clamping brackets (U-brackets) must always be fitted to the unstressed end of the rope, the clamping jaws

(saddle) must always be fitted to the strained rope („never saddle a dead horse“).

During tightening the nuts have to be tensioned equally (alternately) until the required tightening torque is

reached.

The required tightening torques with lubrication apply to wire rope clips whose

bearing surfaces and the threads of the nuts have been greased with Panolin CL

60 multipurpose lubricant spray (or an equivalent lubricant).
