Description
Technical Field
The utility model relates to the field of wave beam steel guardrails, in particular to an upstream end of a wave beam steel guardrail.
Background
The main accident forms at the end of the guardrail include that the vehicle collides with the upstream end of the guardrail to cause the guardrail plate to be inserted into the vehicle body, the vehicle drives out of the road from the outside of the end to collide with other obstacles or fall off a slope, etc. Mishandling of the tip can exacerbate the severity of the accident. Reasonable end setting can reduce the accident severity to a certain extent.
When the corrugated beam steel guardrail straddles the side ditch, if the upright posts are buried in the side ditch, drainage efficiency of the side ditch can be affected, so that the problem that upright posts are not arranged in the road side drainage ditch of the excavation section usually exists in the conventional corrugated beam steel guardrail, and the guardrail can not better play a protective role when a vehicle is in an accident. In addition, the design that the end part of the end head is not buried in soil body or anchored easily causes secondary damage to the vehicle because the guardrail is inserted into the vehicle body when the vehicle collides with the guardrail.
In view of the above, the present utility model provides an upstream end of a corrugated beam steel guardrail, which solves the above technical problems.
Disclosure of utility model

When the cutting cover is implemented, water flows from the cutting cover side ditch 4 to the cutting integral side ditch 3, the upright posts 21 cross the drainage ditch through the cutting integral side ditch 3, and the edge of the guardrail 2 is in contact with a slope body of the slope protection. Existing corrugated barriers 2 typically do not provide posts 21 on the drain across the drain, but the lack of posts 21 can result in a reduction in the overall strength of the barrier 2.
The present utility model solves this problem by providing a cutting integral gutter 3 connected to the upright 21.
As shown in fig. 1-5, the cutting integral side ditch 3 is poured into a square shape by a circle of concrete layer 31, an angle steel bracket 32 and an embedded anchor bracket 25 are embedded at the top of the concrete layer 31, the embedded anchor bracket 25 is L-shaped, the angle steel bracket 32 is connected with the bottom end of the embedded anchor bracket 25, the upper end of the embedded anchor bracket 25 is exposed out of the concrete layer 31, and the exposed part of the embedded anchor bracket 25 is provided with threads; the bottom of the guardrail 2 is provided with a base flange 23, and the upper end of the embedded foundation bracket 25 is connected with the base flange 23 through a threaded nut, so that the guardrail 2 is fixedly connected with the cutting integral side ditch 3.
