INSTALLATION METHOD OF PRECAST BOX CULVERT
PROBLEM TO BE SOLVED: To provide an installation method of a precast box culvert that enables a precast box culvert to be installed in a same direction as a transport direction.SOLUTION: An installation method of a precast box culvert includes: a transport step in which a lower box 1a and an upper box 1b that have been rotated in a horizontal direction are respectively mounted on a carrier 2 for the lower box and a carrier 3 for the upper box, and transported inside a precast box culvert 1 already installed toward an installation location; a lower box lifting step in which the lower box 1a is lifted from the carrier 2 for the lower box; a lower box rotation step in which the lower box 1a is rotated to resume its orientation for installation, on a pit face side of the lower box 1a already installed; a lower box installation step in which the lower box 1a is installed at the installation location; an upper box lifting step in which the upper box 1b is lifted above the lower box 1a already installed; an upper box rotation step in which the upper box 1b is rotated to resume its orientation for installation; and an upper box installation step in which the upper box 1b is installed at the installation location.SELECTED DRAWING: Figure 2
【課題】搬送方向と同一方向に設置していくことができるプレキャストボックスカルバートの設置方法を提供する。【解決手段】水平方向に回転させた下ボックス１ａと上ボックス１ｂとをそれぞれ下ボックス用台車２、上ボックス用台車３に積載して、設置済みのＰＣボックスカルバート１の内を設置箇所に向けて搬送する搬送工程と、下ボックス１ａを下ボックス用台車２から持ち上げる下ボックス揚重工程と、設置済みの下ボックス１ａよりも切羽側で、下ボックス１ａを回転させて設置する向きに戻す下ボックス回転工程と、下ボックス１ａを設置箇所に設置する下ボックス設置工程と、上ボックス１ｂを設置済みの下ボックス１ａよりも上方に持ち上げる上ボックス揚重工程と、上ボックス１ｂを回転させて設置する向きに戻す上ボックス回転工程と、上ボックス１ｂを設置箇所に設置する上ボックス設置工程と、を有する。【選択図】図２
