【摘要】：地坑窑院以纯生土为材料建造,源于自然、融于自然、归于自然,是典型的能源自维持住宅。但水患是其致命的灾害,一旦遭遇连续降雨或短时强降雨就会造成院毁窑塌的灾难性事故。因此建立地坑窑院防水患机制,提高窑居自身防御水患的能力始终是地坑窑院民居面临的挑战。本文以豫西地坑窑院民居为研究对象,探讨了强降雨作用下地坑窑院防水患机制,分析其构成及运行模式,提出了基于运行计算模型的评价方法,对地坑窑院防水患机制运行有效性进行定量分析。分析表明:地坑窑院防水患机制的组织要素及构成方式提供了一个立体的水患综合防御体系,它具有良好的防排水能力;经计算,当窑背土体进行压实处理使渗透系数小于0.06 mm/min时,防渗排水能力最优;渗井深度6~8 m的设置是合理可靠的。
[Abstract]:The pit kiln is built of pure raw soil, originated from nature, blended with nature, attributed to nature, and typically derived from the maintenance of housing. However, flooding is a fatal disaster, once continuous rainfall or short-term heavy rainfall will lead to a catastrophic accident of the destruction of the kiln. Therefore, it is always a challenge for the dwelling houses to establish the mechanism of preventing flooding and improve the ability of protecting themselves from flooding. This paper discusses the flood prevention mechanism of ground pit kiln under heavy rainfall, analyzes its composition and operation mode, and puts forward the evaluation method based on the operation calculation model, taking the residential houses of Dikeng kiln in the west of Henan province as the research object, and discusses the mechanism of flood prevention in the ground pit kiln under heavy rainfall. Quantitative analysis was carried out on the operational effectiveness of the waterproofing mechanism in the pit kiln. The analysis shows that the organizational elements and composition of the flood prevention mechanism in the pit kiln provide a three-dimensional comprehensive water disaster defense system, which has a good capability of water prevention and drainage. The calculation shows that the seepage prevention and drainage capacity is the best when the permeability coefficient is less than 0.06 mm/min when the soil is compacted on the back of the kiln, and the setting of the depth of the seepage well of 6 ~ 8 m is reasonable and reliable.
