The safest way to compact soil.

It also yields information on the water contents at which a soil can best be compacted in order to obtain a particular dry density;

This load cannot be used to transfer tractive force, however, and can compress the ground if the tires are too small.

It is necessary to pay special attention on good preparation of an underground: at first fall asleep a ground, well condense it, put a layer of clay or butobetona.

The methods of wine-making are very traditional and natural, so of course harvest is done by hand and they use horses for the plowing to avoid compressing the soil.

You should not condense too soil - it will be difficult for seeds (or even it is impossible) to ascend.

Said, of course, you need to thicken the ground to get the required capacity for continuous footings or foundation slab.

This is especially true when the soils are compacted while being installed.

This results in maximum crop yields, while preserving soil from compaction and erosion.

The soil compaction system was formed from the soil to be compacted together with the compaction device acting on it.

Soils under adverse conditions may become compacted, that is, the soil loses its structure.

In medium and heavy soils, compaction occurs in particular in the area of the plough sole.

However, floods can, in some cases, result in part from soil not performing its role of controlling the water cycle due to compaction or sealing.

It has been estimated that nearly 4% of soil throughout Europe suffers from compaction22, but no precise data are available.

The magnitude of these fluctuations depends on the direction in which the compacting device is being guided over the soil to be compacted.

The magnitude of these fluctuations depends on the direction in which the compacting device is being guided over the soil to be compacted.

An advantage of this previously known roller is, in particular, that the high loads in the segments having a weak curvature are no longer inserted into the ground to be compacted as line loads with corresponding undesirable side effects, such as unintentional shearing stresses, but that these are greatly reduced since the forces are introduced into the ground via as wide a stand-up surface of the roller as possible.

During vibration, a roller with a cylindrical surface not only applies normal forces on a ground to be compacted but also shearing stresses which, depending on the ground, are very undesirable.

In this way, only normal forces are transmitted by the segment when it is on the ground to be compacted, but no shearing stresses.

FIGS. 1 and 2 shown an inventive device for introduction of a foreign material into the ground, in particular for production of material columns in the ground, or for compacting the ground.

The inventive device makes possible a rational and, in comparison to the hitherto conventional devices, an economical and rational processes for introduction of foreign materials in the ground or for compacting the ground.

For example, in June 1986, the leaders of an ongoing joint research project on traffic-induced soil compaction, involving institutes in the Fed eral Republic of Germany, The Netherlands and the United Kingdom, met at Silsoe, England, to inform each other of their progress and discuss possible modifications to the work in the light of their findings.

In medium and heavy soils, compaction occurs mainly in the area of the plough sole, in light soils, especially in the subsoil.

In this way, the soil to be compacted by the tamper foot/soil contact element is compacted multiple times and with impact pulses succeeding one another rapidly, resulting in additional compacting of the earth.

The lower carriage 1 comprises a soil contact plate 13 which has on its underside a contact surface 3 for introducing the pulsing compressive force generated by the vibration plate into the soil 4 to be compacted, and an unbalance exciter 2 with a hydraulic motor, formed as directed vibrator, which generates an intermittent exciter force which is substantially oriented vertically, which is introduced into the soil contact plate 13 .

The roller body 23 comprises a drum 11 which has the contact surface 3 for the introduction of the generated pulsing compressive force into the soil 4 to be compacted, and an unbalance exciter 2 with a hydraulic motor formed as circular vibrator, which generates an exciter force which is intermittent with respect to its direction of action and which is introduced into the drum 11 .

By way of example, it may have a guide pole, a guide frame or a guide bow for pulling or pushing the implement over the ground to be compacted or for holding and controlling the implement.

The guide apparatus allows a user to guide the implement over the ground to be compacted, for example soil.

The progressively condensed ground then yields downwards, which renders the compaction process and, in particular, long compaction intervals even more inefficient.

Essential here initially is that, with a constant energy input into the soil, the compaction of the soil increases logarithmically with the number of load changes.
