DEVICE FOR PILE FOUNDATION FOR MACHINES WITH DYNAMIC LOADS AND VIBRATION-SENSITIVE EQUIPMENT Russian patent published in 2020 - IPC E02D27/44 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in construction of pile foundations for machines with dynamic loads or vibration-sensitive equipment on any non-rocky soil. Method of pile foundation for machines with dynamic loads and vibration-sensitive equipment includes installation in the grill body of vertically oriented injection jigs with elevation of one end above top edge of grillage and deepening of other end into soil base under its sole or concrete preparation, through which is injected movable cement-sand mortar. Prior to injection of cement-sand mortar on pile foundation, maximum dynamic load is applied from machine mounted on pile foundation or from vibration exciter near pile foundation. Pile foundation vibration level is measured. Injection of cement-sand mortar is performed until controlled level of oscillations of pile foundation does not decrease to safe for operation pile foundation, machine or vibrosensitive equipment level.

EFFECT: technical result consists in reduction to safe level of oscillations of pile foundation, machine or vibrosensitive equipment in the simplest way without complex tests and calculations using available equipment, longer service life of machines and equipment, reduced negative impact on surrounding building structures.
