Problems solved by technology
[0004] Although the method of air extrusion and drainage to strengthen soft soil foundation and the airbag used can make the reinforced foundation soil into a composite foundation, and its bearing capacity will be further improved, but there are disadvantages in the implementation process , the airbag body needs to be detected and regularly replenished with gas to keep the pressure of the pressed soil constant, which is time-consuming and laborious, and the drainage speed is slow. In addition, the airbag needs to be withdrawn before filling the cavity formed by the airbag with sand and soil materials. In the process of withdrawing the airbag, the cavity is easy to collapse, and the effect of filling sand and soil is poor;

Embodiment Construction
[0039] In order to make those skilled in the art better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0040] see figure 1 shown;
[0041] A soft soil foundation reinforcement device based on intelligent active drainage, comprising an unfolding mechanism 10, a rigid shell 20 that can be folded and unfolded, that is, the housing 20 has a folded state and an unfolded state; the outer wall of the housing 20 is fixed with drainage The bottom of the casing 20 is covered with a filter layer 23. When the casing 20 is inserted into the soft ground in a folded state, the unfolding mechanism 10 can be inserted into the casing 20, and the unfolding mechanism 10 expands to expand the casing 20 to squeeze the soft body The foundation soil forms a water storage cavity 25 inside the shell 20; and a plurality of drainage racks 30 that can be placed in the water storage...

The invention discloses a soft soil foundation reinforcement device based on intelligent active drainage, which belongs to the technical field of soft soil foundation reinforcement treatment. The invention is provided with an unfolding mechanism; a hard shell that can be folded and unfolded; It is connected with a drainage board, and the bottom of the housing is covered with a filter layer. When the housing is inserted into the soft ground in a folded state, the expansion mechanism can be inserted into the housing and follow the expansion of the expansion mechanism. Expanding the shell to squeeze the soft foundation soil to form a water storage cavity inside the shell; and a plurality of drainage racks that can be placed in the water storage cavity, and the drainage racks can be connected with the The inner wall of the casing is flexibly connected, and the invention has the advantages of convenient use, high drainage efficiency, short construction period, good filling effect of sand and soil, and favorable effects of improving the bearing capacity after the soft soil foundation is reinforced.
Description
technical field [0001] The invention relates to the technical field of soft soil foundation reinforcement treatment, in particular to a soft soil foundation reinforcement device based on intelligent active drainage. Background technique [0002] At present, the definition of soft soil foundation in my country's highway industry standard refers to the soft soil layer with low strength and high compression, most of which contain a certain amount of organic matter. Great harm, such as improper handling, will have a great impact on the construction and use of highways. Commonly used soft soil foundation treatment methods include sand and gravel replacement method, cement mixing and reinforcement method, heap load preloading method, vacuum preloading method, etc. , the above methods are relatively mature, and each has its own applicability, advantages and disadvantages; [0003] A Chinese patent is disclosed in the prior art, the application number is 200710057012.8, the applicati...
