1.1 本指南涵盖了在侵蚀控制、水工结构铠装和保护以及保护应用中通常存在的现场条件下安装土工合成水泥基复合垫（GCCM）的说明。 1.2 以国际单位制为单位的数值将被视为标准。括号中以英寸-磅为单位的数值仅供参考。 1.3 本指南包含一般指南。它不是为了取代项目特定的安装要求。如果两者之间存在冲突，项目规范的要求将取代本指南的要求。 1.4 这不是一个包罗万象的指南，有些项目将超出本指南的范围。 1.5 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。 1.6 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 本指南确定了GCCM设计师、检查员和安装人员使用的适当布局、安装和水合程序以及设备。 4.2 应用程序- 典型的GCCM应用可能包括但不限于: 4.2.1 水工结构铠装或保护，包括但不限于:沟渠、洼地、运河、水槽和其他类似结构。 4.2.2 边坡防护。 4.2.3 护堤和堤岸衬砌和保护。 4.2.4 涵洞仰拱衬砌。 4.2.5 涵洞入口和出口的冲刷防护。 4.2.6 现有混凝土渠道和结构的修复。 4.2.7 排水口和溢洪道的衬砌。 4.2.8 割草条或杂草抑制。

1.1 This guide covers directions for the installation of a geosynthetic cementitious composite mat (GCCM) under field conditions typically present in erosion control, hydraulic structure armoring and protection, and protection applications. 1.2 The values in SI units are to be regarded as the standard. Values in inch-pound units are in parentheses for information. 1.3 This guide contains general guidelines. It is not intended to replace project-specific installation requirements. In the event of a conflict between the two, the requirements of the project specifications will supersede the requirements of this guide. 1.4 This is not an all-inclusive guide, and some projects will be beyond the scope of this guide. 1.5 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. 1.6 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 This guide identifies proper layout, installation, and hydration procedures along with equipment for use by GCCM designers, inspectors, and installers. 4.2 Applications— Typical GCCM applications may include but are not limited to: 4.2.1 Hydraulic structure armoring or protection, including but not limited to: ditches, swales, canals, flumes, and other similar structures. 4.2.2 Slope protection. 4.2.3 Berm and bund lining and protection. 4.2.4 Culvert invert lining. 4.2.5 Scour protection at culvert inlets and outlets. 4.2.6 Remediation of existing concrete channels and structures. 4.2.7 Lining of outfalls and spillways. 4.2.8 Mow strips or weed suppression.
