Problems solved by technology

[0008] In recent years, the soft soil foundations formed by a large number of marine tidal flats and dredging and dredging are urgently needed to be developed and utilized. However, the traditional soft soil foundation treatment method has a long cycle and high cost, and the foundation bearing capacity is low, and a large amount of materials need to be transported from different places Replacement, not only destroys the ecological environment, but also has poor durability, and the contradiction between economic development and environmental protection has become increasingly prominent

Abstract

The invention relates to a curing agent, in particular to a silt compounded curing agent which is prepared from the following components in parts by mass: 20-50 parts of an inorganic material adhesive, 2-5 parts of an activator and 2-10 parts of an organic matter surfactant. The silt compounded curing agent is mainly acted on silt, can replace the traditional construction process of vacuum preloading, rockery skin changing and filling and dynamic compaction and can be used for foundation treatment of expressways, municipal roads, storage yards and various building places.

Description

technical field [0001] The invention relates to a curing agent, in particular to a sludge composite curing agent. Background technique [0002] Traditionally, dredging fill silt and underlying soft soil layer foundation treatment methods mainly include drainage consolidation method, gravel (sand) pile replacement method, cement-soil mixing method, etc. Gravel (sand) pile displacement method and cement-soil mixing method engineering cost are all more expensive, are not suitable for adopting in a large area. Traditionally, a large number of applied treatment methods are drainage consolidation methods: according to different loading and drainage forms, drainage consolidation mainly includes surcharge preloading method, vacuum preloading method, vacuum well point dewatering method, vacuum electroosmosis dewatering combined with low energy strong Tamping method and low vacuum preloading method. [0003] A brief overview of two commonly used traditional dredging fill foundation ...
