Passive zone pressure deformation active control device, system and method for foundation pit engineering

Abstract

The application discloses a kind of foundation pit engineering passive area pressure deformation active control device, system and method.The pressure deformation active control device, system and method of the application include counterforce pile (1), counterpressure bottom plate (3) and counterpressure control device (2);The counterforce pile is arranged in the soil of foundation pit bottom;The counterpressure bottom plate is covered on the soil of foundation pit bottom;The counterpressure control device includes top force transmission structure (2-2) and loading device (2-1);The top force transmission structure is firmly connected with counterforce pile, and there is loading device accommodating space between top force transmission structure and counterpressure bottom plate, the loading device is placed at the loading device accommodating space, and loading device exerts downward dynamic pressure on counterpressure bottom plate based on top force transmission structure.The pressure deformation active control device, system and method of the application can realize good control effect to the upward deformation of passive area soil of foundation pit bottom.
