a method for installing an animal isolation protection net on the outer side of a highway guardrail comprises the steps of embedding and fixing guardrail stand columns along the lines of two sides of a highway, sequentially installing isolation nets which are manufactured in a standardized mode in a blocking mode on the outer sides of exposed portions of the guardrail stand columns, arranging a base plate between each isolation net and each guardrail stand column, arranging a pressing strip on the outer sides of the isolation nets, sequentially penetrating the pressing strips, the isolation nets and the base plates through self-tapping screws, and penetrating the pressing strips, the isolation nets and the base plates into the guardrail stand columns, so that the pressing strips, the isolation nets and the base plates are tightly fixed on the guardrail stand columns, wherein the base plates are vertically arranged along the exposed portions of the guardrail stand columns and are at least located at the upper portions, the middle portions and the lower portions of the exposed portions of the guardrail stand columns, the pressing strips are vertically provided.

Furthermore, the isolation net is higher than the guardrail upright post, and the top of the isolation net is bent outwards to form an arc.

Further, the installation of the tapping screw is achieved by an electric portable drill.

Furthermore, the isolation net is made of low-carbon cold-drawn steel wires, and is subjected to anti-corrosion treatment by adopting zinc plating, plastic spraying and paint spraying.

Furthermore, the diameter of the plastic dipping silk of the separation net is 4.5-5mm, and the meshes of the separation net are 30 x 30.

Furthermore, the pressing strip and the base plate are subjected to anti-corrosion treatment by hot galvanizing and plastic spraying.

Furthermore, the pressing strips are made of 3-30 mm steel strips, the backing plates are made of 5-100 mm steel plates, and the tapping bolts are 100mm long and 8mm in diameter.

The beneficial effects of the invention are mainly as follows:

the isolation net is manufactured in a standardized way in blocks, is simple to manufacture and is fast and convenient to replace; the layering, the separation net and the backing plate are tightly fixed on the guardrail stand columns, a single layering can simultaneously press a plurality of adjacent guardrail stand columns, the backing plate is at least located at the upper portion, the middle portion and the lower portion of the exposed portion of the guardrail stand columns, the layering is arranged according to the backing plate, the whole separation net is not prone to deformation and falling after being installed in place, the separation net is firm in fixation and tight in plugging, and the phenomenon that small wild animals, poultry and livestock are pressed or collided due to the fact that the small wild animals, the poultry and the livestock enter a highway can be.

Detailed Description

The invention is further described below with reference to the figures and examples.

As shown in figures 1 to 3, a method for installing an animal isolation protection net outside a guardrail of an expressway comprises the steps of firstly embedding and fixing guardrail upright posts 1 along the lines of two sides of the expressway, then sequentially installing isolation nets 3 which are manufactured in a standardized manner in a blocking manner at the outer sides of the exposed parts of the guardrail upright posts 1, arranging a backing plate 4 between each isolation net 3 and each guardrail upright post 1 when each isolation net 3 is installed, then arranging a pressing strip 2 at the outer side of each isolation net 3, and finally sequentially penetrating the pressing strip 2, each isolation net 3 and the backing plate 4 through self-tapping screws 5 and penetrating the corresponding guardrail upright post 1, so that the pressing strips 2, the isolation nets 3 and the backing plates 4 are tightly fixed on the guardrail upright posts 1, wherein the backing plates 4 are vertically arranged along the exposed parts of the guardrail upright posts 1 and are at least positioned at the upper parts, the middle parts and the lower parts of the exposed parts of the guardrail upright posts 1, a single compression bar 2 can simultaneously compress a plurality of adjacent guardrail posts 1.

The isolation net 3 is manufactured in a standardized way in blocks, is simple to manufacture and is fast and convenient to replace; the layering 2, the separation net 3 and the backing plate 4 are tightly fixed on the guardrail upright posts 1, a single layering 2 can simultaneously press a plurality of adjacent guardrail upright posts 1, the backing plate 4 is at least positioned at the upper part, the middle part and the lower part of the exposed part of the guardrail upright posts 1, the layering 2 is arranged according to the backing plate 4, the whole separation net 3 is not easy to deform and fall off after being installed in place, the fixation is firm, the plugging is tight, and the phenomenon that small wild animals, poultry and livestock are pressed or collided due to entering a highway can be effectively avoided.
