Method and device for improving the soil-mechanical properties of soil in the amphibian water - country - transition region from bodies of water, low spots and subgrade rehabilitation areas

摘要

A method for improving the soil-mechanical properties of soil in the amphibian water - country - transition region from bodies of water, low spots and subgrade rehabilitation areas, in the case of the:as a carrier unit is used a amphibian operating hydraulic excavator,the holding device during the process is supported on the floor to be improved and thus the low detected precisely,as a vibration source as a function of the depth of water and the required compaction depth in the bottom depth vibrator, vibrators for vibration ram boring machine - or pulling devices or vibratory plates are used, the weight of at least 1,5 mg and a slight vibrating pressure compression is carried out,the vibrators of the vibration source with beam or vibrating boards in a different embodiment of the construction of the number and length of the oscillation rods are combined,a fixed connection of the holding device with the vibration source to the bottom excited via rigid mechanical elements and solid, uniaxial joint connections, so that, when the tamping-in pressure compression in addition to the weight of the vibration source by means of the holding device is a pressing force is exerted on the vibration source, andcontinuous or discontinuous stroke - and lowering movements of the vibration source in the measuring paths freely selectable and accompany as well as process can be carried out digitally determined, be prepared and processed,as a result of which, inter alia, depth or path, time and work and jolt of the vibration source are measured and per tamping-in attachment point can be represented graphically and the base of water in the vicinity of low spots or for alkaline earth - and foundation construction of the devices do not accessible wetting surfaces without additional dam directly piles as a working plane of the holding device can be used for soil improvement.
