Problems solved by technology

In terms of material selection for the isolation grid column, some use steel. This type of isolation grid uses a large amount of steel, so the cost is high. In addition, there are some isolation grids made of composite materials, but the strength of the inner column and Resilience needs to be improved

Abstract

The invention discloses a separation fence vertical column and a manufacturing method thereof, and relates to a continuous guardrail which is extended along a road or is positioned between lanes, and a manufacturing method for the continuous guardrail. The separation fence vertical column has the advantages of low cost, and high intensity and toughness. The separation fence vertical column comprises a column body and a screen fixing part which is fixedly connected to the outer side of the column body; the column body comprises hollow cylindrical outer skin and an inner core which is tightly attached to the inner surface of the outer skin; the inner core consists of a composite rod and cured slurry; the composite rod sequentially comprises non-woven fabric layers, glass fiber fabric layers, and a sponge rod and bamboo reinforcements from outside to inside, wherein the sponge rod and the bamboo reinforcements are loosely wrapped in the glass fiber fabric layers; the cured slurry is filled in space among the glass fiber fabric layers, the sponge rod and the bamboo reinforcements; the slurry comprises brine, magnesium oxide and saw dust in a mass ratio of (20-25):(38-42):1; and the brine is prepared from halogen powder and water, and the concentration of MgCl2 in the brine is 23 to 30 mass percent.

Description

technical field [0001] The invention relates to a continuous guardrail extending along a road or between lanes and a preparation method thereof, in particular to an isolation grid column and a preparation method thereof. Background technique [0002] The isolation fence column has a wide range of applications. It can be used to close highways, railways and other traffic lines to prevent people and animals from crossing the lines and causing danger and affecting driving safety. It can also be used as fences in grasslands, municipalities, parks and other public places. play a blocking role. In terms of material selection for the isolation grid column, some use steel. This type of isolation grid uses a large amount of steel, so the cost is relatively high. In addition, there are some isolation grids made of composite materials, but the strength of the inner column and Resilience needs to be improved. Contents of the invention [0003] The technical problem to be solved by t...
