淤泥固化土可用于多类工程建设，能够替代抛石挤淤填筑的传统工艺，解决沿海石料不足及破坏山体的问题，减少了大量石料的运输，用资源循环利用的方式达到了节能减排的效果。　　Sludge solidified soil can be used in many kinds of engineering construction, which can replace the traditional process of riprap and silt compaction filling, solve the problem of insufficient coastal stones and damaging mountains, reduce the transportation of a large number of stones, and achieve the effect of energy conservation

　　1.相比淤泥，淤泥固化土各项物理指标有了极大的改善，能够满足沿海地基材料的使用要求;相比抛石，淤泥固化土作为地基材料无不均匀沉降。　　1. Compared with sludge, the physical indexes of sludge solidified soil have been greatly improved, which can meet the application requirements of coastal foundation materials; Compared with riprap, sludge solidified soil as foundation material has no uneven settlement.　　2.淤泥固化土的强度来源主要是自身的胶凝骨架结构，其次是物理压实度，故作为地基材料时控制指标有

　　淤泥固化技术概述　　Overview of sludge solidification technology　　现有技术中，河道清淤技术主要包括以下几种：1、排干清淤：通过修建临时围堰，把待施工段的河道截封住，然后抽排水进行干挖作业或水力冲洗，以实现清淤的目的;2、水下清淤：通过借助清淤船作为施工平台，将一系列清淤装置放在船上，然后可直接在水面上进行淤泥开挖作业，再通过输送管道将开挖出来的淤泥运输到岸上堆放场;3、环保清淤：通过使用专业环保清淤设备，实现二次污染防治，保证有效的清淤深度和位置[1]。　　In the existing technology, the river dr

　　综合治理建设内容包括：河道内淤泥固化处理、截污、调蓄池、行洪能力的保持和提升、以及长期水质在线监测系统等。浦东河为黑臭河道，通过综合治理要求水体不黑臭，　　The construction contents of comprehensive treatment include: solidification treatment of sludge in the river, sewage interception, regulation and storage tank, maintenance and improvement of flood discharge capacity, long-term on-line water quality monitoring system, etc. Pudong river is a black and smelly river. Through comprehensive tr

　　河道淤泥固化处理工艺，包括以下步骤：　　The solidification treatment process of river sludge includes the following steps:　　预处理：采用泵水设备将河道内的表水抽排干净，直至露出河道底部的淤泥;　　Pretreatment: pump the surface water in the river channel with water pump equipment until the sludge at the bottom of the river channel is exposed;　　步骤一：对待固化处理的河道段的淤泥进行深度测量获得该河道段的淤泥深度，以及对该河道段的淤泥进行取样获得淤泥样本，对淤泥样本进行测试分析得出该河道段淤

　　目首先使固化剂与淤泥接触前就与水混合形成固化剂混合液，省去了常规工艺中洒干粉导致的配比不精确，固化剂干粉散布不均匀的问题，同时大大节约了固化剂的用量;　　Firstly, the curing agent is mixed with water before contacting with sludge to form the curing agent mixture, which eliminates the problems of inaccurate proportion and uneven distribution of curing agent dry powder caused by spraying dry powder in the conventional process, and greatly saves the amount of curing agent;　　其次，利用带旋喷的固
