住宅的室内排水问题集中表现在两个方面:一是室内排水不畅,造成首层住户遭污水浸泡,影响正常生活;二是首层地漏向室内泛臭气,由此造成室内污染,影响居民的身心健康。 目前,室内排水系统多采用横支管集中污水再排向立管,由主管将污水送至水平横管,最后从横管排向室外管网的办法。对多层建筑而言,立管污水由上而下呈加速状态,在一层水平弯头处骤然减速,而生活污水必然含有部分难溶之物,所以仅有3‰坡度的水平排水管留有沉积物实属难免,若清理不及时堵塞管道随即发生。为解决此问题,多层住宅一般都设清通设备,如立管设检查口,楼层设清扫口。但通过调查发现,一层横管堵塞的机率特别大,而住宅又不便内设检查井,所以必须采取其
The problem of indoor drainage of residential buildings is concentrated on two aspects: First, poor indoor drainage causes the first-level households to be soaked in sewage, which affects normal life; second, the first-floor floor drain leaks indoor odor, causing indoor pollution and injuring residents. Physical and mental health. At present, indoor drainage systems mostly use horizontal branch pipes to collect sewage and then discharge them to risers, and the supervisors send the sewage to the horizontal cross pipe and finally from the horizontal pipe to the outdoor pipe network. For multi-storey buildings, the riser sewage is accelerated from top to bottom, suddenly decelerating at a horizontal elbow, and the domestic sewage must contain some insoluble matter, so there is only 3 ‰ gradient of horizontal drainage pipe to stay The presence of sediments is inevitable, if the cleaning does not immediately block the pipeline immediately. In order to solve this problem, multi-storey houses are generally equipped with clear-air equipment, such as standpipes and inspection openings, and floors with sweeping openings. However, through surveys, it was found that the probability of blockage in one layer of cross-tubes was particularly high, and the house was inconvenient to install inspection wells, so it was necessary to adopt them.
