固化技术是处理高含水率淤泥类软土的有效方式之一在我国沿海地区港口、河道、湖泊清淤过程及城市地下空间开发的过程中,会产生大量的高含水率淤泥,其承载力低较低,目前主要采用填埋、堆弃的方式对其进行处理,我国每年仅抛入海洋的淤泥量超过2亿m3,陆地填埋也需大面积场地作为淤泥填埋场,相应地会对地下水、土资源产生污染。 In the process of dredging ports, rivers, and lakes in coastal areas of China, as well as the development of urban underground spaces, a large amount of high moisture content sludge is generated, with low bearing capacity. Currently, landfilling and dumping are mainly used to treat it. China only throws over 200 million cubic meters of sludge into the ocean every year, and land landfilling also requires a large area of land as a sludge landfill site, which will correspondingly pollute groundwater and soil resources. 固化技术是处理高含水率淤泥类软土的有效方式之一,在短期内可迅速提高软土强度,加固后的淤泥软土可做建筑地基和路基回填料。传统的固化材料主要以水泥、生石灰为主,该类固化剂在生产过程中不仅消耗大量的能源,同时固化材料生产过程中还会产生大量的co2,对生态环境造成严重污染,目前该类固化材料仍为软基处理领域中最常见的加固材料。 Solidification technology is one of the effective ways to treat high moisture content sludge soft soil, which can quickly improve the strength of the soft soil in the short term. The reinforced sludge soft soil can be used as building foundation and roadbed backfill. The traditional curing materials mainly consist of cement and quicklime. This type of curing agent not only consumes a large amount of energy during the production process, but also generates a large amount of CO2 during the production process, causing serious pollution to the ecological environment. Currently, this type of curing material is still the most common reinforcement material in the field of soft foundation treatment. |
