The guardrail net on both sides serves as a more basic protective isolation device. There are two options for the column: pre-embedded and flange. After the columns are fixed, the guardrail mesh pieces on both sides are connected to the columns through anti-theft screws. Therefore, the guardrail nets on both sides are completely anti-theft after installation. But there is one method that cannot be avoided, which is violent dismantling. Cut the wire with powerful pliers. This situation is attributed to huge profits and dismantling. But then again. If this method is used, even the cement walls will be damaged. Then there is the saying that you should guard against villains and not against righteous people.
The characteristics of both sides of the guardrail net: the product structure is simple and uses less materials, so the project cost is low; it is very convenient for long-distance transportation; the bottom of the guardrail is integrated with the brick-concrete wall, which effectively overcomes the shortcomings of insufficient stiffness of the net and enhances the protective function; in When installing guardrail nets on both sides, it is necessary to accurately grasp the materials of various equipment, especially the precise positions of various pipes buried in the roadbed, and no damage to underground equipment is allowed during the construction process.
When the columns of the guardrail net are driven too deep, the columns must not be pulled out. If the guardrail nets on both sides are used as anti-collision guardrails, the appearance quality of the product depends on the construction process. During the construction, attention should be paid to the combination of construction preparation and pile driver. Continuously sum up experience and strengthen construction management to ensure the installation quality of guardrail nets. To correct it, it is necessary to re-tamp the foundation before driving in, or adjust the position of the column. When approaching the depth during construction, attention should be paid to controlling the hammering intensity. If the flange is to be installed on a highway bridge, pay attention to the positioning of the flange and the control of the top elevation of the column.
