《建筑给水排水设计规范》GB50015—2003（2009年版）（以下简称建排）第4.5.1排水管材选择应符合下列要求:1小区室外排水管道,应优先采用埋地排水塑料管;4.5.2A小区生活排水检查井应优先采用塑料排水检查井。

Specification for design of building water supply and drainage GB50015-2003 (2009) (hereinafter referred to as the build row) first 4.5.1 drainage pipe option shall meet the following requirements: 1 residential outdoor drainage pipes, should first USES the underground drainage pipes; 4.5.2 of A village life plastic drainage drainage inspection Wells should first check well.

1.1 塑料排水管道在小区雨排水设计中的应用

1.1 plastic drainage pipes in residential application of rain water drainage design

根据建设部《关于发布化学建材技术与产品的公告》精神，应用于排水的新型管材主要是塑料管材，其主要品种包括：聚氯乙烯管(PVC-U)、聚氯乙烯芯层发泡管(PVC-U)、聚氯乙烯双壁波纹管(PVC-U)、玻璃钢夹砂管(RPMP)、塑料螺旋缠绕管HDPE、PVC、聚氯乙烯径向加筋管(PVC-U)等。目前塑料管道已被国内外广泛应用在城市供水、城市排水、建筑给水、建筑排水、热水供应、供热采暖、建筑雨水排水、城市燃气、农业排灌、化工流体输送以及电线、电缆护套管等领域。

According to the ministry of construction the release of chemical building materials technology and product announcementsplastic pipe material, its main varieties include: polyvinyl chloride (PVC -u), polyvinyl chloride (PVC) core layer foam pipe (PVC -u), PVC double-wall corrugated pipe (PVC -u), glass steel sand tube (RPMP), plastic spiral coil pipe radial reinforced HDPE, PVC, polyvinyl chloride (PVC -u), etc. Now plastics pipe at home and abroad have been widely used in urban water supply, urban drainage, buildings water supply, drainage, hot water supply, heating, building water drainage, urban, agricultural irrigation and drainage, gas, chemical liquid transportation, as well as wire and cable to protect casing, etc.

居住小区内的排水管和雨水管，宜采用埋地排水塑料管、承插式混凝土管或钢筋混凝土管。近年来小区排水管道较小管径的（D400及以下）必须采用排水塑料管。这是因为，首先，在管道铺设安装方面，塑料埋地排水管的优点也非常特出：重量轻、长度大、接头少，对于管沟和基础的要求低，连接方便，施工便捷。其次，在使用寿命、耐腐蚀方面，塑料管的优点最为突出。埋地排水管输送的生活污水和雨水具有腐蚀性(雨水流过地面时常溶入腐蚀性物质)，或成酸性或成碱性，生产污水如工业排水更是具有强腐蚀性，塑料埋地排水管的耐腐蚀性远胜于金属管。也明显优于混凝土管。同时，塑料埋地排水管的抗磨损性也很好。

Residential area within the drainage pipe and storm sewer, appropriate USES underground drainage pipe plastic pipe, socket type concrete or reinforced concrete pipe. Drainage pipe diameter smaller village in recent years (D400 and below) drainage pipes must be used. This is because, first of all, in terms of pipeline installation, plastic underground drainpipe are very unique as well as advantages: light weight, large length, less joints, low to the requirement of pipe trench and foundation, convenient connection, construction is convenient. Secondly, in terms of service life, corrosion resistance, the advantages of plastic pipe. Underground drainage pipe conveying sewage and rain water is corrosive (rain often into corrosive substances) flows through the ground, or into acidic or alkaline, such as industrial production sewage drainage but also has strong corrosive, plastic underground drainpipe corrosion resistance than metal. Is obviously better than that of concrete pipe. At the same time, the wear resistance of plastic underground drainpipe is also very good.

1.2 塑料检查井在小区雨排水设计中的应用

1.2 plastic check well rain drainage design, the application of the residential area

塑料检查井荷兰、日本早在20世纪80年代出就开发应用，与塑料排水管相配套使用，可以解决上述问题。近年来，国家、多省市要求推广预制检查井（塑料预制检查井、混凝土预制检查井），逐步淘汰砖砌井。原建设部2007年第659号公告《建设事业“十一五”推广应用和限制禁止使用技术(第一批)》以及《建筑给水排水设计规范》GB50015—2003（2009年版）规定，优先采用塑料检查井。另外《建筑小区排水用塑料检查井》(CJ/T233﹕2006)《建筑小区塑料排水检查井应用技术规程》（CECS227:2007）国标图集08SS523《建筑小区塑料排水检查井》陆续颁布。这些都从政策和标准化层面为塑料检查井的推广起到了推动作用。塑料检查井单井造价是砖砌检查井的74%～94%，折合每年的成本只是后者的30%～38%（塑料检查井使用寿命按50年、砖砌检查井寿命按20年计）。塑料检查井价格优势还是很明显的。所以在建筑小区内应该优先采用塑料检查井。

Plastic check well Holland, and Japan in the early 1980 s, the development and application, using plastic drain pipe matching with, can solve the above problems. In recent years, the country, many provinces and cities, the promotion of precast inspection Wells (plastic precast inspection well, prefabricated concrete inspection well), phasing out brick Wells.
