Device for building dams

, The invention relates to a device for the construction of

Dams and is particularly used in the construction of railway tracks or routes.

Methods and devices for building dams are known. For example, RU 20 22 105 describes a method for building dams in which a transport track is laid in a first step, the track bed is filled with dam construction soil (sand, gravel) in a second step, then the transport track is removed and the dam is leveled. These steps are repeated until the required height of the dam is reached.

The disadvantage of this solution is that the amount and therefore the height of the dam construction soil that can be applied is limited, because the rails must not be covered with dam construction soil. They must remain passable.

The object of the invention is to create a possibility to protect the rails from large quantities of embankment soil discharged from rail vehicles.

This object according to the invention is achieved with the characterizing features of the first claim. Advantageous embodiments are the subject of the subclaims.

When transport tracks are laid, essentially vertical wall elements are arranged to the right and left of each rail, and the dam construction soil is placed between the inner wall elements of the rails forming a track and outside the outer wall elements, this prevents large quantities of dam construction soil from falling onto the rails.

The wall elements are advantageously arranged on the sleepers, whereby they can be locked in the essentially vertical position. Furthermore, in one embodiment, the invention provides that the wall elements preferably have cutouts in the area between the sleepers, the height of which is such that dam construction soil that penetrates through the cutouts reaches the respective rail foot, but does not cover the head.

The wall elements are either detachably connected to the sleepers or they are arranged so that they can be folded down to the side of the respective rail. This ensures that the advantage of stacking the transport tracks to and from the construction site is still guaranteed.

The height of the wall elements within the transport track is dimensioned so that there is no collision with the axles and the wagon substructure. The possible height of the outer wall elements is determined by their arrangement on the sleepers. If arranged in the area below the wagon, the height is limited by the ground clearance of the wagon; if arranged to the side of the wagon, it can be chosen to be higher.

The invention is explained in more detail with reference to the drawing.

In Fig. 1, a transport track consisting of sleepers and rails 2 is shown, in which wall elements 3 are arranged almost vertically on both sides of each rail 2 and can be locked in this position. These wall elements 3 are in the area between the sleepers 1

provided with cutouts 4 which are dimensioned such that the embankment soil placed between the inner wall elements 3.1 of the rails 2 forming a track and outside the outer wall elements 3.2 reaches the respective rail foot, but cannot cover the rail head.

In Fig. 2, the device according to the invention is shown on the right with wall elements 3.1 and 3.2, and on the left the application of dam construction soil in the conventional manner. The right part of Fig. 2 clearly shows that with the device according to the invention, significantly more dam construction soil can be applied in one operation without restricting the ability of the rails to be driven on.

The height of the wall elements 3.1 within the transport track is dimensioned so that there is no collision with the axles and the wagon substructure. The possible height of the outer wall elements 3.2 is determined by their arrangement on the sleepers. If arranged in the area below the wagon, the height is limited by the ground clearance of the wagon; if arranged to the side of the wagon, it can be chosen to be higher.

In order to ensure that the transport tracks remain stackable after dismantling, the invention provides that the wall elements 3 can be folded down laterally from the respective rail 2 or are detachably connected to the sleepers.

The wall elements 3 are folded down or released when the transport track is picked up.

Claims (4)

Protection claims 1. Device for building dams consisting of a transport track from which dam construction soil is spread from transport wagons, characterized in that When transport tracks are laid, essentially vertical wall elements (3) are arranged to the right and left of each rail (2), which prevent the dam construction soil laid out between the inner wall elements 3.1 of the rails 2 forming a track and outside the outer wall elements 3.2 from falling onto the rails (2). 2. Device according to claim 1, characterized in that the wall elements (3) in the area between the sleepers (1) have cutouts (4) which are dimensioned such that penetrating embankment soil can reach the respective rail foot through the cutouts (4) but cannot cover the rail head. 3. Device according to claim 1, characterized in that the wall elements (3) can be inserted into the sleepers (1). 4. Device according to claim 1, characterized in that 30 the wall elements {3} are connected to the sleepers (1) in such a way that they can be locked in an almost vertical position, otherwise they can be folded down to the side from the respective rail (2). 35
