Description

坑外横向支撑的基坑支护结构Foundation pit support structure with lateral support outside the pit

技术领域Technical field

本公开涉及一种坑外横向支撑的基坑支护结构,属于建筑技术领域。The present disclosure relates to a foundation pit supporting structure that is laterally supported outside the pit, and belongs to the field of construction technology.

背景技术Background technique

在楼宇建设或者地下结构建设时,一般对地面进行明挖作业,以形成基坑。现有技术中常常通过在基坑的周边设置竖向桩,在坑内设置横向支撑的基坑支护结构来防止基坑周边的土壤发生坍塌。During the construction of buildings or underground structures, open excavation operations are generally performed on the ground to form foundation pits. In the prior art, vertical piles are often installed around the foundation pit and foundation pit support structures with horizontal supports are installed in the pit to prevent the soil around the foundation pit from collapsing.

从结构上说,当前建筑的基坑支护多采用垂直支护桩加坑内水平支撑或斜拉锚杆来抵抗坑外土壤的推力,基坑内水平支撑对施工有妨碍作用,并且成本很高,地下室施工结束后还需要拆除水平支撑。而且水平支撑在施工时,人力物力耗费惊人,也造成工期时间很长。Structurally speaking, the foundation pit support of current buildings mostly uses vertical supporting piles plus horizontal supports or cable-stayed anchors in the pit to resist the thrust of the soil outside the pit. The horizontal supports in the foundation pit hinder the construction and are very costly. After the basement construction is completed, the horizontal supports will also need to be removed. Moreover, during the construction of horizontal supports, the expenditure of manpower and material resources is staggering, which also results in a very long construction period.

而斜拉锚杆尽管也是提供对抗土推力的结构,然而土质往往并不理想,而且要伸入建筑基坑以外很远才能得到有限的抗力,伸的太远也不允许,太短又不可靠,很容易造成整体土体的倒塌,现实中经常有基坑坍塌事故发生,造成道路坍塌或人员伤害。Although cable-stayed anchors also provide a structure that resists soil thrust, the soil quality is often not ideal, and they have to extend far beyond the building foundation pit to obtain limited resistance. Extending too far is not allowed, and it is too short and unreliable. , it is easy to cause the collapse of the entire soil mass. In reality, foundation pit collapse accidents often occur, causing road collapse or personal injury.

以上两种现有技术一次性投资很大,待地下室完成后,其使命完成,不能重复使用,浪费极大。The above two existing technologies require a large one-time investment. After the basement is completed, its mission is completed and cannot be reused, which is a huge waste.
