Vacuum preloading, anatonosis and curing combined treatment equipment and method for dredging sludge
The invention belongs to the technical field of water conservancy projects and geotechnical engineering, and discloses vacuum preloading, anatonosis and curing combined treatment equipment and methodfor dredging sludge. Through a flocculation effect of added magnesium oxide and gas injection anatonosis, vacuum preloading drainage efficiency is improved, and a treatment effect is improved. In addition, carbonization gases are injected to enable the added magnesium oxide to generate curing reaction to further improve the strength of a soil mass. The vacuum preloading drainage, the anatonosis and carbonation curing can be realized through a horizontal drainage board, i.e., one board has multiple purposes to lower construction cost, and processing efficiency is improved. In the invention, thevacuum preloading drainage, the anatonosis and the curing are simultaneously and continuously carried out at intervals, in addition, multiple times of construction are not required, so that operationis convenient and can be easily implemented, processing efficiency is greatly improved, and construction cost is saved. In addition, since gas injection carbonation construction time is controllable,the problem that drainage efficiency is quickly lowered since the vacuum preloading drainage and the curing are simultaneously carried out is avoided.
本发明属于水利工程及岩土工程技术领域，公开了一种真空预压、增渗、固化联合处理疏浚淤泥的设备与方法，通过加入氧化镁的絮凝效果和注气增渗来提高真空预压排水效率，提高处理效果，另外通过注入碳化气体使得加入的氧化镁发生固化反应，进一步提高土体强度，真空预压排水、增渗以及碳化固化都可以通过水平排水板实现，即一板多用从而降低了施工成本，提高了处理效率。本发明中真空预压排水、增渗和固化同时、间隔、连续进行的，且不需要多次施工，操作简便易行，大大提高了处理效率，节约了施工成本；并且，由于注气碳化施工是时间可控的，避免了真空预压排水与固化同时进行导致的排水效率迅速降低问题。
