Sentry Barrier TL-4 ThrieBeam System
– Installation
Getting Started
The
Sentry Barrier TL-4 ThrieBeam System
is a ThrieBeam barrier designed to run the length of
need required and is attached to a compatible terminal end or crash cushion through a designated
transition, refer to the
Appendices
section. For guidance on minimum Length of Need (LON), refer to
the
Length of Need
section earlier in the manual.
Preparation
Before installing an
Sentry Barrier TL-4 ThrieBeam System
, ensure that all components required
for the system are on site and have been identified. The
Sentry Barrier TL-4 ThrieBeam System
is
an engineered safety device. Before starting installation ensure familiarity with the makeup of the
system. Refer to the Bill of Materials and Parts Identification sections in this manual for more
information.
Ensure that the area where the
Sentry Barrier TL-4 ThrieBeam System
is to be installed is
sufficiently flat so that the posts and ThrieBeam can be installed within the allowable tolerance and
aligned to the terminal ends or crash cushions. Minor site grading may be required.
Soil Conditions
The
Sentry Barrier TL-4 ThrieBeam System
has been designed to withstand a constant static
load, thermal loading, and dynamic impact load that can be applied from the impact of an errant
vehicle. To perform, the
Sentry Barrier TL-4 ThrieBeam System
must be attached to either a semi
rigid or rigid terminal end or crash cushion after a designated transition region to provide the
necessary safety benefits. It is recommended that the soil tests are carried out at the location the
Sentry Barrier TL-4 ThrieBeam System
prior to being installed.
IF SOIL CONDITIONS ON SITE DO NOT MEET OR EXCEED THE REQUIRED
STRENGTH DETAILED IN THIS MANUAL, SITE SPECIFIC FOUNDATIONS MUST BE
DESIGNED BY A LOCAL GEOTECHNICAL ENGINEER
