Embodiment Construction

[0026] Such as figure 1 As shown, the guardrail of the present invention is composed of two half guardrails 1, and the two half guardrails 1 are connected by connectors. A rolling device is arranged inside each half guardrail 1, wherein the rolling device is a caster or a roller. In this embodiment, the rolling device adopts casters 2 to achieve the purpose of rapid movement. When the guardrail needs to be moved, the guardrail is tilted, and the rolling effect of the casters is used to quickly move to the roadside or other places; A chamfer is cut at the bottom of the back side, so that it can maintain a stable state when it is placed freely, but the horizontal force applied to it will lose the stable state and cause a tilting effect, so that it is convenient for demolition personnel to quickly tilt it by their own strength Guardrail: two arc-shaped buffer devices are installed at both ends of the upright back of the guardrail, and the guardrail will move along the arc-shape...

Abstract

The invention discloses a separated concrete barrier with longitudinal connection capable of moving rapidly and a manufacturing method thereof. The separated concrete barrier comprises a first semi-barrier positioned on one side and a second semi-barrier positioned on the other side; the first semi-barrier is connected with the second semi-barrier detachably by adopting a connecting piece; a rolling device and a buffer structure are arranged inside the first semi-barrier; and the rolling device and the buffer structure are also arranged inside the second semi-barrier. The barrier provided by the invention consists of two semi-barriers; a detachable connecting piece is arranged between the two semi-barriers; simultaneously a trundle and a buffer device are arranged on each semi-barrier; the assembly of the two semi-barriers can be detached conveniently; the arrangement of the trundle facilitates the movement; therefore, the separated concrete barrier can not only effectively ensure theanti-collision performance and the safety of the barrier, but also ensure the flexibility of the disassembly of the barrier, and can be used for rapidly switching between the requirements on different functions of an expressway.

Description

technical field [0001] The invention is a design method for a separated concrete guardrail with fast movement and longitudinal connection, which can be used to design a new type of movable anti-collision guardrail for expressways, and can retain the good anti-collision effect of the concrete guardrail while meeting the requirements for quick removal of the guardrail , can be applied to the central divider of some special road sections, which is convenient to adjust the traffic function and use of the road, such as using the expressway as a temporary takeoff and landing runway. The invention belongs to the technical field of road auxiliary facilities. Background technique [0002] Guardrails, as the main safety facilities on highways, have been widely valued by people all over the world. Statistics show that among the road traffic accidents in our country, about 45% of the accidents on the common arterial roads and about 30% of the accidents on the expressways are caused by ...
