An electroosmosis composite vacuum preloading system for reinforcing a soft soil foundation comprises a horizontal drain header, a horizontal branch drain, a vertical drainage plate and a vacuum pump. The electroosmosis composite vacuum preloading system is characterized in that the horizontal drain header, the horizontal branch drain and the vertical drainage plate are covered with geotextile fabric, the geotextile fabric is covered with a vacuum film, seal ditches are formed in the periphery of a soil body covered with the vacuum film, the edges of the vacuum film are deep in the seal grooves, the outer sides of the seal ditches are enclosed by water retaining partitions, the height of the water retaining partitions is higher than that of the vacuum film, a drainage channel, a positive electrode and a negative electrode are arranged in the vertical drainage plate, and the positive electrode and the negative electrode are connected with an external power supply through leads penetrating through the vacuum film. In the electroosmosis composite vacuum preloading system, the positive electrode and the negative electrode which are arranged in the vertical drainage plate are utilized to implement electroosmosis treatment, not only can free water be drained, but also a good effect is achieved on drainage of weakly bound water. After being arranged in the drainage plate, the positive electrode and the negative electrode can be well protected, corrosion of the positive electrode and the negative electrode is reduced, service lives of the electrodes are prolonged, a system structure is simplified, and it is favorable for reducing cost.
Description
Technical field
The utility model relates to a kind of electric osmose composite vacuum prepressing system for reinforcing soft ground.
Background technology
Blowing filling soft soil foundation water content is high, clay content is high and soil body osmotic coefficient is little, therefore discharging consolidation difficulty, if adopt piling prepressing or vacuum preloading, duration and posterior settlement that need to be longer be larger, if adopt dynamic compaction easily to form spongy soil, if although adopt electroosmotic drainage to have good drainage effect to only depend on the selfweight stress of the soil body to be difficult to make soil body densification.
Utility model content
In order to overcome the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of electric osmose composite vacuum prepressing system for reinforcing soft ground of discharging consolidation better effects if.
The utility model solves the technical scheme that its technical problem adopts: for the electric osmose composite vacuum prepressing system of reinforcing soft ground, comprise horizontal drainage supervisor, horizontal drainage arm, vertical drainage plate and vacuum pump, it is characterized in that: described horizontal drainage supervisor, horizontal drainage arm and vertical drainage plate top are coated with geotextiles, geotextiles top is coated with vacuum diaphragm, the soil body of covering vacuum film offers sealing ditch around, the edge of described vacuum diaphragm deeply seals in ditch, dash partition wall is surrounded and be provided with to the outer periphery of described sealing ditch, the height of dash partition wall is higher than the height at vacuum diaphragm place, described vertical drainage plate is interior with drainage channel and positive and negative electrode, described positive and negative electrode passes vacuum diaphragm by wire and connects external power supply.
In the utility model, utilize the both positive and negative polarity being arranged in vertical drainage plate to implement electric osmose processing to the soil body, not only can discharge Free water, and the discharge of weak binding water is also had to good effect; Positive and negative electrode can be protected after being arranged in band drain preferably, alleviates the corrosion that it is subject to, and increases the application life of electrode, and has simplified system architecture and be conducive to reduce costs.In addition, the height of dash partition wall is higher than the structure of the height at vacuum diaphragm place, also make negative-pressure sealing precipitation be implemented, make recharge water can cover vacuum diaphragm top completely, in this process, vacuum diaphragm is subject to the compressing of water, and then the soil body of vacuum diaphragm below is also oppressed, and then realize effective vacuum preloading, be conducive to the discharge of water in the soil body.
