Column concrete directional discharging and pouring construction method
The invention discloses a directional discharging and pouring construction method for column concrete. The method comprises the following steps: (1) preparing concrete mortar: Q1, selecting cement with the strength of 42.5 or above, selecting yellow sand with the granularity of 2.8 mm-3. 2mm, and selecting stones with the granularity of 10 mm-20 mm; and Q2, cement, yellow sand, stones and water are mixed and stirred according to the proportion of 1: 1.37: 2.78: 0.46 to form the concrete mortar. A mode of vertically pouring concrete grout is adopted, so that the concrete grout is vertically injected into the #-shaped stirrup along the thin-wall funnel and the steel pipe, the concrete grout passes through the steel pipe and then vertically and freely falls to the middle of the bottom of the column, and the concrete grout is uniformly extruded to the periphery from the middle and then uniformly moves upwards along the formwork wall, so that the continuity of concrete grout pouring is ensured; no hole is formed in the formwork edge, and the surface of the column is smooth after formwork removal.
本发明公开了一种柱砼定向放料浇筑施工方法，（1）制备混凝土砂浆：Q1：选取强度为42.5以上的水泥，选取2.8mm‑3.2mm粒度的黄砂，选取10mm‑20mm粒度的石子；Q2：以比例为1：1.37：2.78：0.46的比例将水泥：黄砂：石子：水进行混合搅拌形成混凝土砂浆。采用垂直浇筑混凝土浆的方式，使混凝土砂浆沿薄壁漏斗和钢管垂直注入井字形箍筋内，混凝土砂浆经过钢管后垂直自由落体掉到柱子底部中间，由中间先统一向四周挤压运动，然后统一沿着模板壁向上运动，保证混凝土浆浇筑的连续性，保证模板边不出现孔洞，拆模后柱表面光滑。
