Grouting type steel stand column for expressway ancillary facilities
The invention relates to a grouting type steel stand column for highway ancillary facilities, which comprises a central grouting pipe, a straight pipe section and a taper pipe section, spiral blades are arranged on the periphery of the straight pipe section, a steel stand column grouting hole is formed in the pipe wall of the straight pipe section, and a grouting pipe grout outlet hole is formed in the pipe wall of the central grouting pipe. The outer side of each grouting pipe grout outlet is provided with a grouting branch pipe, the bottom of the inner end of each grouting branch pipe is hinged to the center grouting pipe, the inner end of each grouting branch pipe is connected with the corresponding grouting pipe grout outlet through a corrugated pipe, and the lower side limiting pipe piece of the grouting type steel stand column is a breakable plastic pipe piece. The grouting branch pipes are provided with grouting stations and lifting stations, when the center grouting pipe moves downwards, the outer ends of the grouting stations are horizontally clamped between the upper side limiting pipe pieces and the lower side limiting pipe pieces, and when the center grouting pipe moves downwards, the outer ends of the lifting stations downwards turn over towards the steel stand column body. The technical problem that in the prior art, an underground concrete pier is adopted as an ancillary facility foundation, and the construction period is long is solved.
本发明涉及一种高速公路附属设施用可注浆式钢立柱，包括中心注浆管和外周设置有螺旋叶片的直管段和锥管段，直管段的管壁上开设有钢立柱注浆孔，中心注浆管的管壁上开设有注浆管出浆孔，各注浆管出浆孔的外侧均设置有注浆支管，注浆支管的内端底部与中心注浆管铰接相连，注浆支管的内端通过波纹管与对应注浆管出浆孔相连，可注浆式钢立柱的下侧限位管片为可折断的塑料管片，注浆支管具有在中心注浆管朝下移动时，外端水平卡入至上侧限位管片和下侧限位管片之间的注浆工位和在中心注浆管朝下移动时，外端向下朝向钢立柱本体翻转的上提工位。本发明解決了现有技术中采用地下混凝土墩作为附属设施地基基础存在的施工周期长的技术问题。
