Grouting construction method for large tree-shaped steel tubular column
The invention provides a grouting construction method for a large tree-shaped steel tubular column, which comprises the following steps: analyzing and determining that grouting holes are formed in the lower part of the steel tubular column and exhaust holes are formed in the upper part of the steel tubular column, and respectively numbering the grouting holes and the exhaust holes; opening a hole and reserving a hole plate; hoisting the steel tubular column in place; valves and pipelines at the exhaust holes and the grouting holes are installed; stirring the grouting material; grouting is conducted; manufacturing a test block; and the exhaust hole and the grouting hole are sealed and subjected to flaw detection. Holes are formed in the lower portion of the steel tubular column for grouting, holes are formed in the top of the steel tubular column for exhausting, smooth grouting construction can be guaranteed, the influence of the grouting holes formed in the top of the steel tubular column on the steel column is avoided, it is guaranteed that no significant adverse influence is generated on the steel tubular column, and the technical problems that construction continuity is poor and grouting compactness cannot be guaranteed in manual gravity grouting are solved.
本发明提供了一种用于大型树状钢圆管柱灌浆施工方法，包括：分析确定灌浆孔设置在钢圆管柱下部，排气孔设置在钢圆管柱上部，并分别对其进行编号；开孔并保留孔板；钢圆管柱吊装就位；排气孔与灌浆孔处的阀门及管道安装；灌浆料搅拌；灌浆；试块制作；排气孔与灌浆孔封闭并进行探伤检测。本发明通过在钢圆管柱下部开孔注浆，顶部开孔排气，能够保证灌浆顺利施工，避免钢圆管柱顶部开灌浆孔对钢柱的影响，确保不对钢圆管柱产生重大不利影响，解决了人工重力灌浆存在的施工连续性较差、无法保证灌浆密实性的技术问题。
