屋面接水工程,是指利用住房屋面承接雨水并加以净化贮藏,以供人畜饮用的民用水利工程设施。近几年来,为解决我区无水源农村的人畜吃水困难,屋面接水工程应运而生。但农户在修建这类工程时,由于没有掌握确定这类工程规模的计算方法,因此对其工程规模大都没有计算。结果,不是因规模偏小造成水不够吃,就是因规模过大造成浪费人力物力。这种现象不仅在我国南方存在,北方的山西、河南等省也存在类似问题。近年来,我们在这类工程设计的实践中,总结出一种确定这类工程规模的简易计算方法,经实际应用证明是可行的。在农村,应用本方法进行这种工程规模的确定时,一个初中生便可自己计算。现将这种计算方法介绍给读者。
Roof water access project, refers to the use of housing roof to undertake rainwater purification and storage for human and animal drinking water civil engineering facilities. In recent years, to solve the water shortage in rural areas of our country people and animals draft, roofing project came into being. However, most of the scale of the project was not calculated by the peasants because they did not know the method of determining the scale of such projects when building such projects. As a result, water is not consumed enough because of its small size, which is a waste of human and material resources because of its large scale. This phenomenon not only exists in the south of our country, but also similar problems in the northern provinces of Shanxi and Henan. In recent years, we conclude a simple calculation method to determine the scale of such projects in the practice of such engineering design, which is proved feasible through practical application. In rural areas, when applying this method to determine the size of such a project, a junior high school student can calculate it himself. Now this method of calculation introduced to the reader.
