Description
Technical Field
The invention relates to the technical field of flexible steel cable guardrails. In particular to a flexible steel cable guardrail and a side slope protective guard which can automatically warn after being collided by vehicles.
Background
The anti-collision guardrail of highway is an important component part of road engineering, and at present domestic and abroad anti-collision guardrail divides three major types, is rigid guardrail (mainly for cement concrete guardrail, new jersey guardrail), semi-rigid guardrail (the main kind is column type wave plate guardrail), flexible guardrail (the main kind is rope class guardrail), and three kinds of guardrails respectively have the major and minor drawbacks: (1) the rigid guardrail (cement concrete guardrail and new Jersey guardrail) has the advantages of high strength, impact resistance, good anti-collision effect and long service life, is commonly used for protecting the outer side of the bridge, but the rigid guardrail has obvious defects that the rigid guardrail has no deformation and can not absorb energy, the vehicle is basically damaged and people die after the vehicle is collided, although the bridge is safe and innocent, the damage to the vehicle is serious, and the loss of lives and properties of drivers and passengers is too large, so that the construction of a harmonious society is not facilitated; (2) the semi-rigid guardrail (a column type corrugated plate guardrail) has the advantages that the semi-rigid guardrail has certain strength, is deformed when impacted, can absorb energy, has small damage loss of vehicles, has a protection effect on cars and trucks with low speed, has the defect that the semi-rigid guardrail has almost no protection capability on freight vehicles with high speed, is easy to damage and needs to be frequently replaced and maintained; (3) the common flexible guardrail has the advantages that the guardrail deforms greatly, the energy absorption is good, the vehicle loss is small when the guardrail is impacted, and the common flexible guardrail has the defects of poor strength, weak protective capability and easiness in damage and needs to be replaced and maintained frequently; the flexible guardrail is only suitable for roads with medium and low traffic and mainly including cars, and the application range is too small.
In addition to the desire to increase the level of protection of flexible crash barriers in the field, it is also desirable that flexible crash barriers further reduce the loss of lives and property of people after being impacted to alert subsequent vehicles to safety concerns.
In addition, when a slope landslide occurs in a side slope mountain, the falling rocks can harm road driving safety, but the falling rocks are random events and are difficult to alarm and warn vehicles driving on the road in time, and the flexible anti-collision guardrail has the prospect of being applied to the side slope and protecting the falling rocks, and needs to be improved to enable the guardrail to have the function of early warning in time.
