Anti-segregation elephant trunk device

The utility model relates to the technical field of civil construction, in particular to an anti-segregation elephant trunk device which comprises a steel column. The elephant trunk is arranged in the steel column in an S shape in the vertical direction, and the top end of the elephant trunk communicates with the top of the steel column. The technical problems that a side opening of the steel column is limited by construction site conditions, and segregation is prone to occurring when concrete is poured from a top opening of the steel column are solved. 本实用新型涉及土建施工技术领域，具体涉及一种防离析溜管装置，包括：钢柱；溜管，沿竖直方向呈S形设置在钢柱内，且溜管的顶端与钢柱的顶部连通。解决了从钢柱的侧面开口受施工场地条件限制以及从钢柱的顶部开口灌注砼易发生离析的技术问题。
