Cast-in-place reinforced concrete silo funnel construction method
The invention discloses a construction method of a cast-in-place reinforced concrete silo funnel, and relates to the technical field of reinforced concrete construction. Comprising the following steps: pouring a supporting beam: firstly, determining the position and the height of the supporting beam according to the position and the size of a funnel, tying a reinforcement cage according to the position and the height, plugging the periphery of the reinforcement cage by using a template, and then pouring, vibrating and solidifying concrete and pouring a discharging opening of the funnel; an annular reinforcement cage is tied according to the size of a feed opening in the bottom of the funnel, and the inner layer and the outer layer of the reinforcement cage are sealed through formworks. On the basis that the bottom pressure is reduced through sectional type pouring, the steel plate is adopted for blocking after each section is poured, the steel plate serves as a medium, and the gravity of top pouring is applied to the reinforcement cage, so that the reinforcement cage bears the load in the axial direction of the reinforcement cage, the load can be prevented from being directly applied to bottom concrete, and the service life of the reinforcement cage is prolonged. Upper-layer construction can be carried out when bottom concrete is not completely solidified, the construction period is shortened, and the efficiency is improved.
本发明公开了一种现浇钢筋混凝土筒仓漏斗施工方法，涉及钢筋混凝土施工技术领域；包括如下步骤：支撑梁的浇筑，首先根据漏斗的位置尺寸确定支撑梁的位置和高度，按照位置和高度扎钢筋笼，并在钢筋笼的四周使用模板封堵，随后进行混凝土的浇筑、振捣和凝固，漏斗下料口的浇筑，根据漏斗底部下料口的大小和尺寸扎环形钢筋笼，并在钢筋笼的内外层使用模板封堵。本发明在采用分段式浇筑降低底部压强的基础上，对于每段浇筑后采用钢板封堵，以钢板作为介质，将顶部浇筑的重力施加至钢筋笼上，从而使其承受沿其轴向的载荷，从而可防止载荷直接施加至底部混凝土上，使得在底部混凝土未完全凝固即可进行上层施工，缩短工期，增加效率。
