METHOD OF CONSTRUCTING ARTIFICIAL GROUND ON SUBBASEMENT TYPE ROAD
PROBLEM TO BE SOLVED: To construct an artificial ground on a subbasement type road at low cost without completely cutting off traffic in service.SOLUTION: A span length of a SPC girder 3 which is designed as a simple girder with a distance L of earth retaining walls 2a, 2b on both the sides of a subbasement type road as the span length and in which a steel frame material is disposed on the compressed side is shorter than l/2; a connecting steel frame 32 projecting from the end surface and a sheath 34 passing a connecting PC steel material therethrough are provided at the tip end of the SPC girder 3. The SPC girder 3 is stretched from the earth retaining walls 2a, 2b to a temporary pad 15 provided at the center of the road. The connecting steel frames 32 are connected to each other; concrete is pored and cured in the connecting part; the connecting PC steel material is inserted into the sheath 34 to introduce prestress to make them integrally connected. The temporary pad 15 is removed, so that the simple girder is formed between the earth retaining walls 2a, 2b. A number of the SPC girders 3 are constructed on the road to construct an artificial ground 10 on the subbasement type road.SELECTED DRAWING: Figure 2
【課題】供用中の道路交通を完全に遮断することなく半地下型道路の上に人工地盤を低コストで構築する。【解決手段】半地下型道路の両側の土留擁壁２ａ、２ｂの距離Ｌを支間長とする単純桁として設計した圧縮側に鉄骨鋼材を配設したＳＰＣ桁３を前記支間長がｌ／２より短い桁長とし、ＳＰＣ桁３の先端部には端面から突出する連結用鉄骨３２と連結ＰＣ鋼材を通すシース３４が設けてあり、このＳＰＣ桁３を土留擁壁２ａ、２ｂから道路中央に設けた仮受台１５に掛け渡し、連結用鉄骨３２同士を連結し、連結部にコンクリー打設して固化させ、シース３４に前記連結ＰＣ鋼材を挿入してプレストレスを導入して連結一体化して仮受台１５を撤去し、土留擁壁２ａ、２ｂの間に前記単純桁を形成する。このＳＰＣ桁３を多数道路の上に構築して前記半地下型道路の上に人工地盤１０を構築する。【選択図】図２
