Crash barriers are generally installed around roads. Like crash walls,
they can reduce the impact of cars coming face-to-face in the event of
accidents. Most of the anti-collision walls are concrete or cement,
because the finished products made of these two raw materials are
relatively strong and durable. The purpose of the anti-collision wall
is to reduce the impact pressure, which naturally requires very strong
materials. No matter when storing molds or cement concrete, they should
avoid touching water, which will reduce their own advantageous
characteristics, fail to bring good results and fail to meet the use
specifications.

The anti-collision wall molds are basically two sheet structures. When
in use, the formwork needs to be transported to the construction site
for cast-in-situ processing, because the setting distance of the anti-
collision wall is related to the length of the highway. If the
production is carried out in advance, the anti-collision wall will not
meet the construction requirements, The molds must be transported to
the periphery of the highway. They need to be spliced during
production. A straight plate and a bent plate are placed separately.
The distance between the two molds is the thickness of the highway
anti-collision wall. If the wall is too thin, the anti-collision effect
cannot be achieved. Generally, the thickness of the anti-collision wall
is more than 20cm, The pull rod at the top of the anti-collision wall
mold needs to be adjusted for the specific thickness. If the wall
thickness is adjusted during each production, all the pull rods must be
adjusted.
