2. Ramming C140 posts
The IPE140 posts must be aligned centrally between the IPE160 posts, as viewed in
the longitudinal direction. The front faces of the posts lie adjacently to the I160 posts
by 175 mm nearer to the carriageway (see Fig. 1).
The minimum 2,000 mm long V140 post is to be driven vertically into the subgrade
with a suitable pile driver, so that the upper edge of the post section is 750 ±40 mm
above the reference level. The open ends of the post sections must be aligned
pointing away from the traffic and the hole pattern 18x36 mm must be on the upper
end of the post section (post head).
The pile driver must be equipped with a suitable drive head to fit the V140 section, in
order to prevent deformation or damage to the hot-dip galvanised coating on the post
head. A guide adapted to the V140 section is to be mounted to the pile driver near
the upper edge of the ground in order to ensure precise positioning of the post during
the pile driving process.
The regulation centre distance of the posts is 1900 mm.

Mounting extension profiles for the upper guard rail belt
The extension profile is to be aligned as a continuous belt between the guard rail belt
and the IPE160 posts.
The trapezoidal cross-section of the extension profile surrounds the centre of the
guard rail. The rectangular holes 18x25 mm in the guard rail axis and extension
profiles must align (see Fig. 2).
The overlapping of the extension
profiles is to be executed in accordance
with the overlapping of the guard rails.
The two drilled 18 mm diameter holes
indicate that the extension profiles in
the jointed area (upper part) are facing
the respective carriageway (see Fig. 2).
The extension profiles are to be
mounted together with the guard rails
and are fixed in place with the bolted
unions in the guard rail axis.
