The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

A lane isolation guardrail is shown in figures 1-3 and comprises a U-shaped frame 1 and a top plate 2, wherein the top plate 2 is movably arranged on the upper edge of the U-shaped frame 1, a plurality of anti-collision barrels 3 are arranged between the U-shaped frame 1 and the top plate 2, and a buffer body is filled in the anti-collision barrels 3, so that the impact force of an accident vehicle can be removed, and the accident vehicle can be prevented from crossing the guardrail.

The contact surface that the frame was erect to roof 2 and U type frame 1 both sides all is provided with mounting hole 7, and the mounting hole 7 of the frame is erect with the both sides of U type frame 1 to mounting hole 7 of roof 2 aligns from top to bottom, and installation double-screw bolt 8 passes mounting hole 7 of roof 2 and the mounting hole 7 of the frame is erect to the both sides of U type frame 1 in proper order, realizes dismantling of roof 2 and U type frame 1 and is connected.

The upper end of the anti-collision barrel 3 is provided with an upper mounting part 9, the lower end of the anti-collision barrel is provided with a lower mounting part 10, the bottom edges of the top plate 2 and the U-shaped frame 1 are provided with fixing holes 4, the upper mounting part 9 and the lower mounting part 10 are respectively embedded into the fixing holes 4, and anti-collision raised lines 11 are evenly arranged on the anti-collision barrel 3.
