水胀密封花管环保注浆施工技术

Construction Technology of Environmental Protection Grouting for Water Expansion Sealing Pipe

随着可持续发展理念的不断深入,节能减排、绿色环保在建筑领域成为一个重要研究方向[1]。传统的花管注浆是用带孔的钢质花管打入或钻孔插入土中,采用压力连续灌浆入土层,提高地基强度,大量应用于软土地基加固处理中[2]。以广州市某广场项目溶洞注浆填充施工为例,通过BIM技术应用以及改良花管注浆设备,采用环保的施工工艺,实现精细化施工,既满足施工要求,节约成本,又达到了节能减排绿色施工的效果,具有广泛的推广意义。

With the continuous development of the concept of sustainable development,energy saving,environmental protection and environmental protection have become an important research direction in the field of construction. The traditional flower tube grouting is driven into or into the soil by a steel tube with a hole,and is continuously grouted into the soil layer by pressure to improve the strength of the foundation, and is used in a large amount of soft soil foundation reinforcement treatment. Taking the karst grouting construction of a square project in Guangzhou as an example,through the improvement of the flower tube grouting equipment,the environmentally friendly construction process is adopted to meet the construction requirements,save costs,and achieve the effect of green construction of energy saving and emission reduction. Has a wide range of promotional significance.
