用于非饮用水非压力地下输送和储存的塑料管道系统 用于保留、滞留、储存和运输系统的箱体 由 PE、PP 和 PVC-U 制成的雨水箱规范

[中文适用范围]： 本文件给出了注塑、挤出、压缩成型和热成型热塑性塑料长方体箱体（包括整体组件）的定义，并规定了最低要求，这些箱体用于地下系统中，用于保留、滞留、储存和运输非饮用水（例如雨水），由聚乙烯 (PE)、聚丙烯 (PP) 或未增塑聚氯乙烯 (PVC-U) 制成。这些箱体用于地下埋置，例如景观、行人或车辆交通区域。在保留和滞留系统中，箱体的主要目的是保留水，以便以后渗入地下或以后用于非饮用水应用（灌溉、清洁、卫生设施等），或在暴雨期间保留水，以受控方式将其转移到公共雨水网络。应用包括商业、住宅、农业和公路排水，包括停车场和道路下的安装。产品性能由材料规格、产品设计和制造工艺的组合决定。箱子可以由不同的组件在工厂组装或现场组装。这些箱子旨在用作模块化系统中的元素，制造商已提供明确记录的方法，说明如何组装组件以创建完整的保留、拘留、储存和运输系统。箱子以一个或多个水平层的形式安装在坚固的基础上，并在整个系统的周围和上方嵌入填充物。注意非承重部件可以通过各种方法制造（例如挤压、注塑、旋转成型、压缩成型、热成型和低压注塑），不在本文件的范围内。 [外文原描述]： This document gives the definitions and specifies the minimum requirements for injection moulded, extruded, compression moulded and thermoformed thermoplastics cuboid shaped boxes, including integral components, used in underground systems for retention, detention, storage and transportation of non-potable water (e.g. storm water) and manufactured from polyethylene (PE), polypropylene (PP) or unplasticized polyvinylchloride (PVC-U). The boxes are intended for buried underground use, e.g. in landscape, pedestrian or vehicular traffic areas. In the case of retention and detention systems, the main purpose of the boxes is to retain water, for later infiltration in the ground or for later use in non-potable applications (irrigation, cleaning, sanitary facilities, etc.) or to retain water during a storm, transferring it in a controlled way to the public storm water network. Applications include commercial, residential, agricultural and highway drainage, including installation under parking lots and roadways. Product performance is determined by a combination of material specification, product design and manufacturing process. A box can either be factory-assembled or site-assembled from different components. The boxes are intended to be used as elements in a modular system where the manufacturer has provided a clearly documented method specifying how the components are assembled to create a complete retention, detention, storage and transportation system. The boxes are installed as one or more horizontal layers on a firm foundation and embedded with fill around and above the complete system. NOTE Non-load bearing component(s) can be manufactured by various methods (e.g. extrusion, injection moulding, rotational moulding, compression moulded, thermoforming and low-pressure injection moulding) and are not within the scope of this document.
