Description
Technical Field
The invention belongs to the field of soft soil foundation reinforcement, and particularly relates to a method for quickly treating sludge of an electric geotextile electroosmosis combined dynamic compaction gravel pile.
Background
A plurality of rivers and lakes are distributed in coastal areas of China, and typical soft soil foundations such as silt soil layers, mud flat silt and the like are formed along with continuous sediment deposition, so that the soft soil foundations have the characteristics of high water content, high pore ratio, high compressibility, low strength and the like. When buildings are constructed on the soft soil foundations, the foundations are firstly reinforced, otherwise, large post-construction settlement is generated, and the safety of the buildings is seriously affected.
The dynamic compaction method is initiated by Menard company in the 60 th century of 20 th century, is also called as a dynamic consolidation method, and is widely applied to reinforcement of foundations such as sandy soil, loess, silt, gravel soil and the like. The dynamic compaction method can eliminate main consolidation settlement and improve the bearing capacity of the soil body, and meanwhile, the equipment is simple and easy to construct. However, when the dynamic compaction is adopted to treat soft clay and sludge, the moisture in the soil body pores is difficult to discharge instantly under the action of dynamic compaction power, the pore water pressure in the soil is increased and difficult to dissipate in a short time, so that the 'rubber soil' phenomenon occurs, the foundation is bulged laterally, the compaction is softer, and the rammer is difficult to pull out.
The electroosmosis drainage consolidation has more advantages for silt and electroosmosis drainage consolidation, the electroosmosis method has short construction period, can treat fine granular soil and silt with high water content, but also has the phenomena of higher energy consumption of post treatment, electrode material corrosion, electrode and soil body separation and the like, and limits the wide application of the electroosmosis method in practical engineering. For the treatment of large-area high-moisture content sludge foundation, the electroosmosis-dynamic compaction combined reinforcement of soft soil foundation is a feasible solution for shortening construction period, improving the strength of the reinforced foundation and reducing comprehensive treatment cost.
The existing electric geotextile arrangement methods such as horizontal arrangement and vertical arrangement have the problems of electrode material waste due to comprehensive spreading, difficulty in layered laying, cable connection (for electroosmosis) and the like, and an operating method capable of efficiently and quickly performing electroosmosis drainage consolidation by using the electric geotextile is still lacked.
