Definitions

the invention relates to a method for introducing pourable Additional material in the soil under the surface of the soil to improve the load-bearing capacity of the soil using a device in the form of a lock vibrator, in particular a Stuffing process with repeated lowering and pulling the lock shaker.
the invention further relates to a Device for introducing pourable additional material into the soil under the soil surface to improve the load-bearing capacity of the bottom in the form of a lock shaker, comprising a feed container with a feed opening, one down vertical sluice tube connected to the feed container with a lower outlet opening and one in the lower area of the lock tube vibrating device.
Gland compression process of the type mentioned above for Soil improvement with the lock vibrators mentioned well known. This involves hanging one on a crane or lock shaker guided by a leader in the ground sunk and coarse material, e.g. Track gravel, coarse gravel or split introduced. By repeated Extend and retract the lock vibrator into the opening a compressed column of coarse material is created in the Ground. The material that originally occupied the bottom opening is displaced and the surrounding soil also within itself condensed. By creating such columns from coarse material In a grid-like arrangement, a building plot with a total of better properties for building. When training and Retracting by an amount of 50 cm, for example each part of the floor opening in the floor by the lock fitter released and at the same time with pourable coarse material filled.
coarse material e.g. Track gravel, coarse gravel or split introduced.
the present invention has the object to provide a method and a device, with which earth-moist sand when performing soil improvements by means of lock vibrators, especially in the stuffing process can be used.
the solution to this is a method in which the earth is humid Sand is used and bridging in the lock vibrator periodically mechanically destroyed and in a device, in which one arranged inside the lock tube Longitudinally movable ripper bar is provided.
a periodic operation in the above is in particular an uninterrupted back and forth Movement, but also with interruptions at intervals performed movements, which then, for example, only must comprise a single stroke. Float here Lift movement and / or rotary movement.
the ripper bar extends from Feed container up to the top of the vibrator.
the Ripper bar can in particular protrude transversely Have hooks to increase their effectiveness with low weight.
the ripper bar can preferably directly from a double-acting actuator cylinder or a rotary actuator can be operated via a crank mechanism, each in the feed container are arranged. These can be either lifting or rotating movements cause.
a longitudinal guide or bearing bush may be provided.
a crawler vehicle 11 is attached to it upright leader 12 is shown, on which a lock vibrator 13 is attached, which can be lowered into the ground.
a feed chute 14 is also fastened so that it can move in height, the in a lower position with solid and in shown in a highest position with dashed lines is.
a loader vehicle 15 can freshly dug sand in the Tilt feed chute 14 in its lower position, the in the upper position of the feed chute 14 in the lock vibrator 13 can be drained.
Crawler vehicle 11 and loader vehicle 15 stand on the floor surface 21 by a first stable bottom layer 22 is formed. Below this there is a less stable floor layer 23. In the floor itself two parallel packing columns 24, 25 are shown, the latter in the vertical axis of the lock vibrator 13 lies. For the production of a further packing column is thus initially the caterpillar 11 to move and then the lock vibrator 13 by means of the leader 12 lower again.
FIG 2 is the lock vibrator 13 with the details Feed container 27, lock tube 28 and vibrator arrangement 29 shown.
the feed container 27 has a filling opening on the side 30, through which the sand from the aforementioned feed chute is introduced.
the feed container 27 has at the bottom a bottom valve 31, with which the feed container 27 opposite the subsequent lock tube 28 can be closed.
At the bottom At the end of the lock tube 28 there is an oblique baffle 32, which is within the cross section of the lock tube 28 built-in vibrator 29 covers and that free cross section of the lock tube 28 to a lower Outlet opening 33 reduced.
the ripper bar is by means of the actuating cylinder 35 36 periodically in the axial direction in the lock tube 28 movable to prevent bridging along the arc line. Bridging means that it forms in the sand self - supporting vault shape, which is a reflow of Sand blocked.
