Benefits of technology

This patented technology allows for easy-to-use methods of treating hardened clay foundations with very low indexes (highly plastisolatic) or without adding any chemicals like cement during excavation work. It also prevents vertical movements caused by gravity loading from settling on top of buildings due to their own weight. Overall this technical effect makes it easier and more efficient than current techniques used today.

Problems solved by technology

This patented technical solution involves improving the performance of an improved type of hydrous material called hardened cement-based materials for use at building sites during heavy rain events caused by snowmelt accumulation over time without causing damage from cracks formed when they are buried deeper below ground level.

Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] see figure 1 , a kind of high plasticity index soft ground foundation treatment method of preferred embodiment of the present invention, comprises steps:

[0032] S1. Clean up the foundation; clean up the work site and make a good drainage system;

[0033] Specifically, the construction site is leveled, rolled or compacted to ensure that the positioning of the pile driver moves and the drilling is vertical. The stirring pile machine is in place; and the test

Abstract

The invention relates to the field of water conservancy projects and discloses a treatment method for a base of a high plasticity index soft soil foundation. The treatment method comprises the following steps: S1, cleaning and leveling the foundation: cleaning and leveling an operating site and preparing a drainage system; S2, carrying out pile driving construction on the ground to form a plurality of sand piles on the ground; S3, detecting qualities of the sand piles; S4, constructing stirring piles on the sand piles, wherein one stirring pile is formed in each sand pile; and S5, detecting qualities of the stirring piles. The method of adopting the sand piles and the stirring piles on the high plasticity index soft soil foundation can solve the problem of coordination of bearing capacityof the foundation of a hydraulic structure and settlement deformation effectively, so that a hidden danger that a centralized water leakage channel under a bottom plate is formed as a basic bottom plate of the hydraulic structure is avoided.
