一种流动化固化淤泥水下浇筑的模拟装置及使用方法A simulation device for underwater pouring of fluidized and solidified silt and its application method

技术领域technical field

本发明涉及一种固化淤泥水下浇筑的模拟装置及使用方法,尤其涉及一种流动化固化淤泥水下浇筑的模拟装置及使用方法。The invention relates to a simulation device and a use method for underwater pouring of solidified silt, in particular to a simulation device for underwater pouring of fluidized solidified sludge and a use method.

背景技术Background technique

近几年我国在黑臭河道治理,河湖综合治理以及海洋疏浚等工程中产生了大量的废弃淤泥,而将淤泥固化处理后进行填土材料利用的实例较多,也成了解决淤泥出路的主要方式之一。最近,除将淤泥固化后在陆地上进行回填、碾压施工以外,利用固化淤泥在水下填筑的工程需求渐趋突出。比如正在设计中的大连湾跨海交通工程中,正在讨论能否利用沉管隧道开挖产生的淤泥用来填筑人工岛;也有一些湖泊希望疏浚产生的淤泥能够通过在湖体内填筑人工岛来解决淤泥的出路问题。与陆地填筑不同,水下填筑的材料因为无法进行碾压施工,如果在不进行碾压的施工工艺下将固化或脱水淤泥填筑水中,一般很难满足作为地基材料的强度和变形要求。这种工况下,流动化固化的工艺成为常用的方法。也就是将淤泥与固化材料混合成搅拌混凝土的状态,在水下进行浇筑使用的方法,如日本的名古屋中部国际机场及羽田机场D跑道均是将海域附近的疏浚淤泥经流动化固化处理后作为人工岛土材料进行水下浇筑施工而形成的。In recent years, my country has produced a large amount of waste silt in projects such as black and odorous river course management, comprehensive river and lake treatment, and ocean dredging, and there are many examples of solidifying silt for use as filling materials, and it has become a solution to the silt outlet. One of the main ways. Recently, in addition to backfilling and rolling construction on land after solidifying silt, the engineering demand for using solidified silt to fill underwater has become increasingly prominent. For example, in the Dalian Bay cross-sea traffic project under design, it is being discussed whether the silt produced by the excavation of immersed tube tunnels can be used to fill artificial islands; there are also some lakes that hope that the silt produced by dredging can be used to fill artificial islands in the lake. To solve the outlet problem of silt. Different from land filling, underwater filling materials cannot be rolled and compacted. If solidified or dehydrated silt is filled in water without rolling, it is generally difficult to meet the strength and deformation requirements of foundation materials. . Under such working conditions, the fluidization and solidification process has become a commonly used method. That is, the method of mixing silt and solidified materials into a state of stirring concrete and pouring it underwater. For example, the D runway of Nagoya Chubu International Airport and Haneda Airport in Japan is to use the dredged silt near the sea after fluidization and solidification treatment. The artificial island soil material is formed by underwater pouring construction.

我国的固化淤泥水下浇筑前景广阔,但现有的一些浇筑装置和测试方法主要是针对混凝土浇筑施工设计的,不能够完全模拟流动化固化淤泥的水下浇筑,并且也不能实现在浇筑同时对水质进行实时监测以及固化淤泥水下围压养护的力学性质实验。The prospect of underwater pouring of solidified silt in our country is broad, but some existing pouring devices and testing methods are mainly designed for concrete pouring construction, which cannot completely simulate the underwater pouring of fluidized solidified silt, and cannot realize the simultaneous pouring of solidified silt. Real-time monitoring of water quality and mechanical property experiments of solidified silt underwater confining pressure conservation.
