摘 要

本文根据国家现有的相关标准和武汉市颁布的相关文件，结合国内及武汉市内已有的清淤工程施工实例，撰写了本规程，旨在指导河流或湖泊的以有效去除水体内源污染物、水质改善和生态修复为目标的环保清淤工程设计、施工、验收，同时指导管网清淤工程的设计、施工以及保证管网清淤的质量和安全。

对于河湖清淤工程，在进行工程设计前需要收集各种资料进行分析论证及了解相关环保要求，工程设计包括清淤范围、深度、方案、堆场、余水等，设计完成后进行施工准备、施工组织以及完成后的施工质量验收。

对于管网清淤工程，工程设计包括清淤范围、清淤量、方案、堆场等，管网清淤作业更加注重依规范标准操作以确保作业安全。

关键词：清淤工程、底泥疏浚、施工、质量验收

Abstract

Based on the existing related national standards and relevant documents issued by the wuhan city, combined with domestic and wuhan city existing dredging engineering construction as an example, wrote this discipline, meant to guide to effectively remove the water from rivers or lakes endogenous pollution, water quality improvement and ecological restoration as the goal of environmental protection dredging engineering design, construction and acceptance, and at the same time guiding pipeline dredging engineering design, construction and guarantee the quality of pipeline dredging and security.

For the river and lake dredging project, it is necessary to collect all kinds of data for analysis and demonstration and to understand the relevant environmental protection requirements before the project design. The project design includes the dredging scope, depth, scheme, storage yard and residual water, etc. After the design is completed, construction preparation, construction organization and construction quality acceptance shall be carried out.

For the pipe network dredging project, the engineering design includes the dredging scope, dredging amount, scheme and yard, etc. The pipe network dredging operation pays more attention to the operation according to the standard to ensure the operation safety.

Key words:Dredging engineering、Sediment dredging、Construction、Quality acceptance
