Embodiment

[0024] The floor plan dimension of a logistics storage building is 200m long, 150m wide, the ground elevation is about 4.30m, the filling height is 1.2m, and there is 10-20m thick muddy clay under the foundation soil. The design load of the building floor is 50kPa . The foundation treatment method proposed by the present invention is used for treatment to meet the bearing capacity and deformation requirements of the floor of the logistics storage building.

[0025] The foundation treatment method for the floor of the logistics storage building is as follows:

[0026] First, the site is leveled, and the settlement observation reference point is set, and then the drainage shaft is laid (the sand material of the drainage shaft meets the specification requirements, and the plane layout and depth meet the design processing and settlement calculation requirements), and light compaction combined with precipitation reinforcement treatment is carried out. After meeting the design cons...

Abstract

The invention relates to a treating method applicable to a deep soft soil foundation of warehouse building floors. The treating method comprises the steps of (1), flattening a foundation field to be treated; (2), setting a plurality of drain shafts according to the reinforced depth and soil conditions of the field; and (3), grouting pipes are hit in the drain shafts, performing grouting treatment from bottom to top to form reinforced cemented soil sand piles, and after the grouting, finishing the treatment of the foundation without pulling out the grouting pipes. Compared with the prior art, a new practical method is provided for soft soil foundations of logistics storehouse building floors, the practical operation is simple and easy to implement, and obvious advantages are provided in economic and technical index.

Description

technical field [0001] The invention belongs to the field of civil engineering, especially the field of foundation treatment, and in particular relates to a treatment method suitable for deep and weak soil foundations of storage building floors, which can effectively improve the bearing capacity of soft soil foundations and reduce the settlement of foundations. The invention is simple Easy to operate, economical and reliable. The patent of the invention belongs to the field of civil engineering, especially the field of foundation treatment. The purpose is to design a treatment method suitable for deep and weak soil foundations of storage building floors, which can effectively improve the bearing capacity of deep and weak soil foundations and reduce the settlement of foundations. Background technique [0002] As an important part of the modern logistics industry, my country's warehousing industry is facing a strong market demand, especially in the deep and soft soil areas alo...
