A BOLLARD CONSTRUCTION METHOD FOR SUPPRESSION OF AN AUTOMOBILE ENTRY

摘要

A construction method of a bollard for controlling entry of a vehicle is provided to absorb shock by bending a column with a spring in bumping a pedestrian or the vehicle into the bollard, and to prevent the bollard from falling down by pouring concrete in a column fixing member. A bollard(1) includes a column(2) restricting access of a vehicle, a column fixing member(3) laid under the ground to support the column, and a spring(4) bending by shock and restoring in removing external force. The ground is excavated, and concrete mixed with quick-setting cement is poured thereon. The bollard assembled with the column is pushed into the concrete, and concrete is charged in an internal section(14) of the column fixing member. The column of the bollard is disassembled in hardening concrete, and pavement blocks(25) are arranged. The gap between the pavement block and the column fixing member is filled with concrete, and the column is combined with the column fixing member in finishing constructing the bollard.
