Bilateral Fence simple structure, with less material, to facilitate the long-range transport, and thus low construction cost; bottom of the fence with brick wall as a whole, to overcome the weakness of the net stiffness, and enhance the protective properties. Bilateral Fence Advantages: The product structure is simple with less material, and thus the project cost is low; 2 very easy remote transport; 3. The bottom of the fence with brick wall as a whole, effectively overcome the weakness of the net stiffness enhanced protective properties; 4. installation not affected by the topography, particularly suitable for hilly areas; 5. efficient anti-corrosion and long service life; attention to matters: 1, in installing the bilateral Fence to accurately grasp the various bilateral Fence installation construction facilities, especially buried in the exact location of the the roadbed various pipeline, causing any damage to underground facilities are not allowed in the construction process. , Give Fence column into the deep not pull out the column correction, based on the re-ram (ben) and then break into, or to adjust the column position. Construction should pay attention to controlling close to the depth hammering efforts. 3, if installed on a highway bridge mounting flange, pay attention to the control of the positioning of the flanges and the pillar top surface elevation. 4 bilateral Fence Fence installation quality can be as a crash barrier, the quality of the product's appearance depends on the construction process, attention should be paid to the construction preparation and the combination of the piling machine, constantly sum up experience, strengthen the construction management, construction guarantee.
