Embodiment Construction
[0031] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited by the examples.
[0032] In the embodiment of the present invention, first prepare a long tubular electric geotextile-gravel pile composite structure, such as figure 1 shown. Among them, the top is designed with a non-slip liner 1 to prevent the geotextile from falling off and entering the bottom of the pit during the penetration of the rammer. The base part of the geotextile is made of polypropylene, nylon, polyester or a mixed woven geotextile 2, and the conductive part Carbon fiber conductive material 3 is used, and the proportion cannot be lower than 5% by mass. Polyester is used as a reinforcement strip 4 for reinforcement treatment on the whole to prevent the geotextile from being broken during the process of driving the rammer. The number of ribs needs to be increased at the bottom to prevent ramming Hammer, crushed stone impact ...

The invention discloses a quick treatment method for sludge of electric geotextile electroosmosis combined with dynamic ramming gravel piles, which belongs to the field of soft soil foundation reinforcement. Electrodynamic geotextiles and gravel piles are used to form a complex, and the sludge is quickly consolidated and reinforced by the method of electroosmosis combined with strong compaction of gravel piles. Electrodynamic geotextiles have high ductility and tensile strength, and can be completely unfolded and formed under low-energy dynamic compaction or static pressure. In the process of low-energy dynamic compaction, the unique tamper design is adopted, the weight can be adjusted, and it is convenient to implement static pressure and uplift in the mud. During the construction process, first use the low-energy dynamic tamping method to fully expand the electric geotextile and penetrate into the soil, fill the geotextile with gravel to make the geotextile and the soil closely contact, form a gravel pile-geotextile composite, and then electric After the water seepage drops to a certain level, replace it with an ordinary rammer for high-energy dynamic compaction, which can give full play to the advantages of the electroosmotic method and dynamic compaction method, and quickly and effectively reinforce the ultra-soft silt.
Description
technical field [0001] The invention belongs to the field of soft soil foundation reinforcement, and in particular relates to a quick treatment method for sludge of electric geotextile electroosmosis combined with dynamic tamping gravel piles. Background technique [0002] There are many rivers and lakes in the coastal areas of our country. With the continuous deposition of sediment, soft soil foundations such as typical silt soil layers and beach silt have been formed, which have the characteristics of high moisture content, high void ratio, high compressibility, and low strength. . When constructing buildings on these soft soil foundations, the foundation must first be reinforced, otherwise large post-construction settlements will occur, which will seriously affect the safety of the buildings. [0003] The dynamic compaction method was pioneered by the French Menard company in the 1960s, also known as the dynamic consolidation method, and is widely used in the reinforceme...
