技术领域 technical field
本发明涉及基坑工程类施工工艺，特别涉及了一种异形基坑的砼支撑加鱼腹梁的组合支撑体系及施工方法。 The invention relates to a foundation pit engineering construction technology, in particular to a combined support system and a construction method of a concrete support and a fish-belly beam for a special-shaped foundation pit.
背景技术 Background technique
随着地下空间的不断开发利用，土建工程不断往纵深方向发展，出现了大量深基坑工程。在基坑工程中，支撑体系对基坑稳定、施工工期和工程造价有着极为重要的作用。目前的基坑支撑主要包括砼支撑和钢支撑两类，在形状规则基坑中一般采用钢管支撑，在异形基坑中由于受力体系复杂，一般采用砼支撑作为内支撑构件。但是，砼支撑存在施工、拆除速度慢，拆除噪音大，成本消耗大，且产生大量建筑垃圾。基于此，韩国工程技术人员发明了一种新型的预应力鱼腹梁支撑形式，并在基坑工程中得到了成功的应用。 With the continuous development and utilization of underground space, civil engineering continues to develop in depth, and a large number of deep foundation pit projects have emerged. In foundation pit engineering, the support system plays an extremely important role in the stability of the foundation pit, construction period and project cost. The current foundation pit support mainly includes concrete support and steel support. Steel pipe support is generally used in regular-shaped foundation pits, and concrete support is generally used as the inner support member in special-shaped foundation pits due to the complex force system. However, the concrete support has slow construction and demolition speeds, high dismantling noise, high cost consumption, and a large amount of construction waste. Based on this, South Korean engineers and technicians invented a new type of prestressed fish-belly beam support form, which has been successfully applied in foundation pit engineering.
通过对现有技术检索发现，现有专利对鱼腹梁支撑的结构和安装进行了说明，且主要针对于标准形式的基坑，未对异形基坑中的砼支撑加鱼腹梁的组合支撑体系进行进一步的研究和阐述。 Through searching the existing technology, it is found that the existing patents explain the structure and installation of the fish-belly beam support, and are mainly aimed at the foundation pit of the standard form, and do not support the combined support of the concrete support and the fish-belly beam in the special-shaped foundation pit system for further research and elaboration.
