METHOD FOR PADDING GROUND BELOW A DUST USING EXCAVATED SOIL, DEVICE FOR REALISING THE SAME, EQUIPMENT FOR COMPACTING SOIL BELOW A DUST AND SOIL-COMPACTING MECHANISM

摘要

BACKGROUND OF THE INVENTION The present invention relates to a method of filling a space under a pipeline with the use of excavated soil, wherein the excavated soil (2) is picked up, transported from a heap of excavated soil (2) to a trench (4). placed in the trench (4), filling the space (5) below at least the pipe (1) with the ground, compacting the soil at the space (5) below the pipe (1) by applying force to the soil by the soil compaction means, 1) a continuous movement of the soil feeding means (13), the soil conveying means (14) and one or two transport means carrying the soil compacting means. The method according to the invention consists in keeping the transporting means for carrying at least the soil compacting organs on the soil surface in a path (16) which is formed during the metering of the excavated soil (2) with the soil dispenser (13) and with soil compaction organs. The invention further relates to a device for sealing underground pipelines by means of a conveyor which comprises at least a filling unit (9) for filling a trench (4) with a tracked track unit (7) for filling the pipeline (1) with the excavated soil (2). (9) a soil feeder (13), a soil conveyor (14) and a soil lifting / lowering support frame (12) relative to the transport means and a hydraulic cylinder and comprising a soil compactor (10) for compacting the soil beneath the pipeline (1). ) having a soil compaction device with driven soil compaction means and a soil compaction structure enabling the latter to move in a plane perpendicular to the means of transport and in a plane perpendicular to the direction of travel of the means of transport. the attachment means has a rigid mounting bracket. The object of the device according to the invention is that the soil dosing means (13) is arranged on the front surface of the crawler unit (7) and is wider, and and in the direction of travel of the transport means, behind the soil discharge area of the soil conveying means (14). The present invention relates to a device for compaction of soil under a pipeline comprising a soil compaction device and a suspension member having a suspension structure on a conveyor, the latter being provided with a soil compaction device.
