1.1 本规程涵盖了使用化学灌浆密封人孔所需的材料、安装技术和检查的建议选择。检修孔或有主动泄漏的检修孔部分应进行维修。要灌浆的检修孔为砖、砌块、现浇混凝土、预制混凝土或玻璃纤维结构。工程师、业主代表或授权检查员将指定检修孔或有主动泄漏的检修孔部分进行检修孔灌浆。 1.2 承包商应负责根据合同文件提供完成人孔缺陷化学灌浆所需的所有劳动力、监督、材料、设备和后续检查。 1.3 灌浆过程中使用的材料、添加剂、混合比和程序应符合制造商的建议，并应适用于应用。 1.4 以英寸-磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 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）。本标准的使用者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》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 3.1 在密封下水道人孔以防止泄漏、裂缝和贯穿件周围的实践中，本规程用作化学灌浆安装指南。其目的是协助下水道业主和工程师、业主代表或授权检查员了解安装方法规范，以及承包商在安装用于人孔密封的化学灌浆时参考。

1.1 This practice covers proposed selection of materials, installation techniques, and inspection required for sealing manholes using chemical grout. Manholes or sections of manholes with active leaks shall be repaired. Manholes to be grouted are of brick, block, cast-in-place concrete, precast concrete, or fiberglass construction. Manholes or sections of manholes with active leaks will be designated by the engineer, owner’s representative, or authorized inspector, for manhole grouting. 1.2 The contractor shall be responsible for furnishing all labor, supervision, materials, equipment, and inspection follow-up required for the completion of chemical grouting of manhole defects in accordance with the contract documents. 1.3 Materials, additives, mixture ratios, and procedures utilized for the grouting process shall be in accordance with manufacturer’s recommendations and shall be appropriate for the application. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 ====== 3.1 This practice is used as a guide for the installation of chemical grout in the practice of sealing sewer manholes from leaks, cracks, and around penetrations. It is attended to assist sewer owners and engineer, owner’s representative, or authorized inspectors for installation method specification and for contractors to refer to during installations of chemical grout for manhole sealing.
