Embodiment Construction

[0027] Preferred embodiments of the present invention are described in detail as follows:

[0028] In this example, see Figure 1~6, a blow-fill soft soil foundation reinforcement treatment system, in which grid-shaped horizontal drainage boards 5 are tiled on the surface of the blow-fill soft soil foundation, electroosmosis anodes 12 and electroosmosis cathodes 10 are arranged vertically along the depth direction of the soil layer, The electroosmosis cathode 10 is extended along the horizontal drainage board 5, and the depth of the soil layer for preliminary reinforcement of the dredged soft soil foundation is calculated according to actual engineering needs, thereby selecting the pre-embedded depth position of the electroosmotic anode 12 in the dredged soft soil foundation , so that the electroosmosis anode 12 is on the bottom and the electroosmosis cathode 10 is on the top, and the electroosmosis cathode 10 and the horizontal drainage plate 5 are tightly bound and fixed to ...

Abstract

The invention discloses a saturated dredger soft soil foundation reinforcing treatment system and a grid-type vacuum preloading and electroosmosis-method combined treatment method. The problems that when a saturated dredger soft soil foundation is treated with an existing vacuum preloading and electroosmosis combined method, the water content of saturated dredger soft soil in the construction initial stage is large, strength is quite low, and therefore workers and machines can not enter a site easily are solved. According to the treatment system and the treatment method, superficial-layer foundation treatment is carried out through a transverse water draining system and an electroosmosis system in the earlier construction stage, and deep-layer foundation reinforcing is carried out through a vertical water draining system in the later stage. Electrodes are vertically arranged, the electroosmosis flow direction of pore water and the vacuum osmosis flow direction of the transverse water draining system are overlapped accordingly, and the treatment efficiency of the vacuum preloading and electroosmosis combined method is improved to the maximum degree; and the superficial layer and the deep layer of the foundation can be reinforced through the arranging manner of the water draining systems. The treatment system and the treatment method have the beneficial effects of being convenient to construct, efficient in treatment and the like, electroosmosis and vacuum preloading are subjected to beneficial effect complementing, and the treatment system and the treatment method are suitable for reinforcing large-area saturated dredger soft soil foundations.

Description

technical field [0001] The invention relates to a treatment method for earth filling and topsoil, in particular to a method for reinforcing soft soil foundation by dredging and filling, which is applied in the technical field of geotechnical engineering. Background technique [0002] Since the reform and opening up, my country's economy and society have developed rapidly, and the construction of infrastructure has made brilliant achievements. The level of economic development in the southeast coastal area ranks among the top in the country, and the further promotion of infrastructure will inevitably lead to a shortage of land resources in this area. A large amount of soft soil is distributed in the coastal areas of our country, and the influence on the project is not the same due to the difference in the thickness of the soft soil. Soft soil has the characteristics of low strength, large settlement, and high moisture content, which often bring great harm to industrial and c...
