1.1 本规程涵盖了临时隔泥栅应用的常见安装和维护程序。本规程基于AASHTO M288。 1.2 本规程适用于将隔泥栅用作垂直渗透拦截器，用于清除地表非集中水流中的悬浮土壤。临时隔泥栅的功能是通过截留和蓄水来截留和允许来自含沙水的土壤颗粒沉降，以减缓运输速度，并为捕获的泥沙提供储存。目的是大大限制水径流对施工现场侵蚀土壤的运输。 1.3 本文介绍的实践旨在确保良好的工艺和质量，但不一定适用于集中流应用。 1.4 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值，因此每个系统应独立于其他系统使用。 将两个系统的值合并可能会导致不符合标准。 1.5 这种做法提供了有组织的信息收集或一系列选择，并不建议采取具体行动。本文件不能取代教育或经验，应与专业判断一起使用。并非本指南的所有方面都适用于所有情况。本ASTM标准不代表或取代必须根据其判断给定专业服务的充分性的谨慎标准，也不应在不考虑项目的许多独特方面的情况下应用本文件。本文件标题中的“标准”一词仅表示该文件已通过ASTM共识程序获得批准。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 正确安装对隔泥栅的有效性能至关重要。本规程介绍了安装和维护拦沙栅的程序，这些程序已被证明能够使拦沙栅的安装有效地重定向和蓄水地表径流，从而提供有效的泥沙控制。 注1: 本标准产生的结果的质量取决于执行该标准的人员的能力，以及所用设备和设施的适用性。符合实践标准的机构 D3740 通常认为能够胜任和客观的测试/采样/检查等。 本标准的用户应注意遵守惯例 D3740 本身并不能保证可靠的结果。可靠的结果取决于许多因素；实践 D3740 提供了一种评估其中一些因素的方法

1.1 This practice covers common installation and maintenance procedures for temporary silt fence applications. This practice is based on AASHTO M288. 1.2 This practice is applicable to the use of silt fence as a vertical permeable interceptor designed to remove suspended soil from overland, non-concentrated water flow. The function of a temporary silt fence is to trap and allow settlement of soil particles from sediment laden water by intercepting and impounding water in an effort to slow the transport velocity and provide storage for sediment to be captured. The purpose is to greatly limit the transport of eroded soil from the construction site by water runoff. 1.3 The practices presented herein are intended to ensure good workmanship and quality, but do not necessarily apply to the concentrated flow applications. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents, therefore each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.5 This practice offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 Proper installation is critical to effective performance of silt fence. This practice presents procedures for installing and maintaining silt fence that have been shown to result in silt fence installations that effectively redirect and impound surface runoff and, thereby, provide effective sediment control. Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors
