Application of the Steel-mould Stair vehicle of Needle Bridge for placing Concrete of spillway Tunnel of the Guozhuang Reservoir

详细介绍了针梁式钢模台车在郭庄水库泄洪洞的应用。针梁式钢模台车施工机械化程度高,人工成本低,立模、脱模时间可以缩短,进度快,且针梁控制精准,模板整体性好,全断面一次成型,衬砌混凝土无错台,表面光滑。

The paper details the application of steel-mould stair vehicles of needle bridge for placing concrete of a spillway tunnel of the Guozhuang Reservoir.Using this stair vehicle, the degree of construction mechanization can be raised; the labour cost can be lowered; the time of concrete works＇ foming and form stripping can be shortened and the construction schedule can be quickened.The accuracy for controlling the concrete placing is good.The concrete form has a good integrity.The full section concrete can be placed at once. The surface of lining concrete is smooth and there is no unevenness on its surface.
