Abstract

The invention discloses a test device and a test method compounding an EKG (electrokinetic geosynthetics) electro-osmosis method with a direct-discharge type vacuum pre-loading combination method. The device comprises an organic glass model slot, wherein holes are formed in the side wall of the model slot, and the holes are sealed by use of rubber plugs; micro pH meters are connected to a conductive plastic water draining board through guide wires and then are connected to a power supply through the rubber plugs; the water draining board is fixed to the inner surface of the bottom of the model slot; the water draining board is connected to a water draining main tube through a plate tube connector; the water draining main tube is sequentially connected to a vacuum tube and a suction flask; the suction flask is arranged on an electronic scale; the suction flask is connected to the vacuum pump; and a water pump controller is connected to the vacuum pump. According to the test device, a soil body is treated by combining an electrode transition cathode direct-discharge vacuum-electro-osmosis method with a no-transition electrode two-sided water-discharge vacuum-electro-osmosis method, so that the pH value changes, the voltage changes and the sedimentation changes in the soil body can be accurately monitored, and therefore, the condition that vacuum pre-loading and electro-osmosis are restrained with each other at an anode according to the conventional vacuum-electro-osmosis method is relieved, the test efficiency is improved, the soil body reinforcing effect is improved, and the reinforced soft soil foundation has relatively high bearing capacity.

Description

technical field [0001] The invention relates to an electrokinetic geosynthetics (Electrokinetic Geosynthetics, EKG) electroosmotic method composite direct discharge vacuum preloading combined method test device and method, and belongs to the technical field of soft soil drainage and foundation reinforcement. Background technique [0002] Although China has a vast territory, the distribution of land use is very uneven. In recent years, a large number of people have gathered in the eastern coastal areas, the infrastructure construction of coastal port provinces and cities has increased rapidly, and urban construction has been changing with each passing day. However, the area of ​​usable land resources has decreased sharply, resulting in the status quo of "more people and less land" and "every inch of land is expensive". Insufficient construction land has become a bottleneck restricting the economic and social development of coastal areas. In order to solve this shortage of la...
