The invention discloses an expanding water absorption and drainage consolidation device which comprises a conical head (1), metal circular pipes (2) and a water-absorption expanding outer bag (7), and is characterized in that two hanging rings (10) are arranged in the middle of the top of the conical head (1); the metal circular pipes (2) are arranged on and connected with the edge of the top of the conical head (1) in a triangular manner; connecting sleeves (6) are arranged at the tops of the metal circular pipes (2); and permeable mud separating cloth (9), an expanding inner bag (4) and an expanding agent (8) are arranged in the water-absorption expanding outer bag (7) sequentially. The expanding water absorption and drainage consolidation device has the benefits that moisture in soft soil can be absorbed quickly by adopting the expanding bags and utilizing a principle that the expanding agent is expanded after absorbing water; the connecting sleeves are arranged at the tops of the metal circular pipes; connecting ropes are arranged at the top end of the water-absorption expanding bag; and the metal circular pipes can be lengthened and the quantity of the water-absorption expanding bag can be increased according to an engineering requirement. The expanding water absorption and drainage consolidation device is suitable for promotion and use, and has the advantages that the expanding water absorption and drainage consolidation device is good in treatment effect, and simple in construction.
Description
technical field [0001] The invention relates to a soft soil foundation treatment method, in particular to an expansion, water absorption and drainage consolidation device, which belongs to the technical field of foundation treatment. Background technique [0002] Soft soil is a general term for silt and silty soil, which is mainly composed of silt deposits with high natural water content, high compressibility, low bearing capacity and a small amount of humus. Soft soil refers to fine-grained soil with high natural water content, large void ratio, high compressibility, and low shear strength deposited in coastal areas, lakes, valleys, and river beaches. It has high natural water content, large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor water permeability, complex layered distribution of soil layers, and The physical and mechanical properties are quite differ...
