Anti-disengaging concrete jacking construction method for box type steel column shaping pump frame
The invention discloses a box type steel column shaping pump frame anti-disengaging concrete jacking construction method which comprises the following steps that S1, a steel pipe column is selected, and a stiffening plate is installed in the steel pipe column; s2, selecting equipment: calculating jacking resistance, and selecting proper equipment; s3, the steel pipe column is treated, specifically, an opening is formed in the bottom of the steel pipe column and connected with an external pump; the steel pipe column is reinforced at the pumping opening; s4, proportioning the concrete; s5, checking and connecting the components: checking the steel pipe column, and connecting the steel pipe column with related pumping equipment; s6, the concrete is conveyed; and S7, concrete jacking is completed, and the pumping equipment is dismantled. According to the invention, the UEA micro-swelling agent, the water reducing agent, the broken stone, the coal ash and the pumping retarder need to be added when the concrete is proportioned, so that the bleeding rate of a concrete mixture can be reduced, and the gas content can be increased, thereby meeting the pumping requirement.
本发明公开了一种箱型钢柱定型泵架防脱空混凝土顶升施工方法，包括以下步骤：S1：选择钢管柱，并在内部安装加劲板；S2：设备的选择：计算顶升阻力，选择合适的设备；S3：对钢管柱进行处理：在钢管柱底部进行开口，与外部泵连接；在泵送口处对钢管柱进行加固；S4：混凝土的配比；S5：部件的检查、连接：对钢管柱进行检查，将钢管柱以及相关的泵送设备进行连接；S6：混凝土的输送；S7：混凝土顶升完成、拆除泵送设备。本发明，混凝土配比时需要加入UEA微涨剂、减水剂、碎石、煤灰以及泵送缓凝剂，可使混凝土拌和物泌水率减小，含气量增加，从而满足泵送要求。
