Abstract

The invention discloses a saline soil foundation treatment method, and belongs to the technical field of constructional engineering. The method comprises the steps that high-pressure water injection holes are formed in the periphery of a road panel on a saline soil foundation, and high-vacuum water absorption holes are formed in the center point; the high-vacuum water absorption holes are blocked,and water is injected into the saline soil foundation from the high-pressure water injection holes; after water in the saline soil foundation is saturated, water injection is stopped, and the high-pressure water injection holes are blocked; and the high-vacuum water absorption holes are opened, and water dissolved with salt is sucked out from the high-vacuum water absorption holes. According to the saline soil foundation treatment method, the high-pressure water injection holes are formed in the periphery of the road panel on the saline soil foundation, the high-vacuum water absorption holesare formed in the center point, a seepage field is formed between the high-pressure water injection holes and the high-vacuum water absorption holes, the salt dissolved in the water is sufficiently discharged out of the soil foundation, the secondary salinization phenomenon of the saline soil foundation is prevented, and the treatment effect of the saline soil foundation is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a treatment method for saline soil foundation. Background technique [0002] Saline soil is the soil with a soluble salt content greater than 0.3% in the surface soil layer at a depth of 1m. Because saline soil is subsidence, salt-swelling and corrosive, it will bring many difficulties and hazards to engineering construction. With the deepening of the national development strategy, there are more and more saline soil projects, so it is very necessary to treat the saline soil foundation. [0003] At present, the saline soil foundation treatment often uses the pre-soaking method to wash away the salt in the soil. This method uses the infiltration of water to transfer the salt in the upper layer to the deep layer. However, the pre-soaking method does not completely remove the salt in the foundation, and the problem of secondary salinization cannot be avoided, and ...
