BACKGROUND OF FEE XUVENTTON

The invention relates to a method for the perpendicular laying of a pipe, prefer ably a steel pipe,, in a groaned preferably earthy ground, wherein the pipe is positinned at first in a perpendicularly aligned manner above a laying location and repetitive force pulses are delivered to a face end of the pipe which is remote from the ground by means of a preferably hydraulically driven striker of a striking apparatus in order to ram said pipe into the ground,· according to the preamble of clairs 1 ,· and a respective striking apparatus and a respective striking plate.

DESCRIPTION OF THE PRIOR AST

Pipes laid perpendicularly in the ground are often used as the basis for foundations of buildings above ground, A broad field of application relates to sound insulation wails, aid on usually consist of pi ate-" shaped sound protection elements which are arranged between supports protruding vertically from the ground and are fined thereto. In order to ensure secure anchoring of the supports; they are introduced info pipes previously laid perpendicularly In the ground. The pipes are then filled with concrete.

The laying of the pipes in the ground occurred up until now by means of a vibrating technology. Vibrating apparatuses are used for this purpose, which drive the pipes perpendionlariy into the ground by means of osc 11.latino elements which are mounted, oh unbalanced masses and which are moved under considerable input of energy. The problematic aspect is the positioning of the pipes which can often only occur in a highly imprecise manner.

The far greater problem in these known methods is the compaction of the ground which occurs in the course of the vibrating process. which renders the laying process even more difficult., and the expenditure of force required for the laying needs to be increased «ltd progressing duration of the laying process,

Methods are already known ( see DE 2S 00 221 hi or DE 197 34 066 ai for example) in which the compaction of the ground is substantially prevented during the laying process and the required energy input is lower than in conventional methods,. Do 29 00 221 ni shoes a r&nmrnq apparatus which is driven by a pressure medium and which comprises a housing in which a striking body is displaesabiy guided and rests on a strike transmission apparatus 11,· which rests on its part on a ramming part 10, i. e, a perpendicularly arranged pipé:,

The functionality: of the invention shall be explained below by reference to an example,

In order to lay a pipe 1 perpendicularly in the ground 2, it is provided in accordance with the invention to position the pipe 1 at first perpendicularly above the laying location 3 and to apply by means of the striker 8 repetitive force pulses onto the striking plate 3 arid thus onto the face end of the pipe 5 remote from the ground 2 in order to ram said pipe into the ground 2,

The pice 1 is fixed in this process by means of a connecting element 22 to the housing 6, which on its part is connected to a construction machine 18, The positioning of the pipe 1 occurs through a respective positioning of the housing 6, whose pocition is predetermined by the construction machine 18, The perpendicular alignment of the pipe 1 occurs by gravity.

The construction machine 18 can be moved in the ambient environment either independently, or i.t can be arranged on a carriage in order to erect a foundation of noise protection walls for example, which are to be mounted parallel to the traffic rails. The construction machine IS comprises a chassis 19 and a jib 20 which is arranged thereon, whose end region 21 which faces away is formed by the striking apparat as 4.. it the pipe 1 is situated at the laying location 3, the striking plate 9 is moved towards the face end 5 of the pipe 1 which is remote fror;· the ground 2, so that at least one of the shoulders

It, 13 protrudes into the interior of the pipe 1. It is thus preferably but not mandatorily provided that the face end 11 of the striking plate 9 also makes contact with the face end 5 of the pipe 1, Since the striking piste 9 is suspended on the housing 6, only a low aligning force is required for the correct movement or placement of the striking plate 9 on the pipe 1, which force can be applied by a construction worker for example. The striker 8 is in a ncn-conrecting position and is now accelerated in order to impact the depression 13 of the sir iking plate 9 in a contacting position and to thus transmit a force pulse over a large area onto said striking plate and thus onto the pipe 1. In the event that the striking plate 9 is moved at first merely towards the face end a of the pipe 1 which is remote from the ground 2, so that at least one of the shoulders 12, 13 protrudes into the interior of the pipe 1, the contact established between the striking plate "S' and the face end 5 of the pipe 1 also occurs in the course of the impact of the strike ίο on the striking plate 9,

Finally, the striker 8 is moved from; the depression 15 back to a non "-con tact ing position, which enables a renewed acceleration of the striker 8 to the cootacting position. As a result of a repetition of this process, the pi.pe 1 is successively driven into the: ground 2 until, the desired end position is reached. The connecting elements 22 can already be released once the pipe 1 is situated in a stable position, which is generally already achieved before reaching the end position.
