    15 20 25 30 2 and causes unnecessarily long disturbance to traffic in cases where a railing is to be mounted on an existing road.
    Brief Description of the Invention The present invention aims to eliminate problems and disadvantages of prior art anchorages for road rail ends. More particularly, the invention aims to create a railing anchor which is faster and easier to assemble and which can be manufactured and assembled at a lower total cost.
    This object is achieved with a railing anchor according to claim 1.
    The invention also relates to a road barrier and a method for anchoring road railings which have essentially the same purpose as above. At least this object is achieved with a handrail according to claim 5 and a method according to claim 6.
    The invention is thus based on the insight that the above object can be achieved by an anchoring unit which has an underside which is intended to face the ground at the anchoring point and in which at least one continuous anchoring heel is accommodated through which an anchoring tube is drivable in the ground by means of device. One end of the anchoring tube and the main part of its longitudinal extent has a cross-sectional dimension which is slightly smaller than the cross-sectional dimension of the anchoring hole so that the tube can be passed down through the hole. The opposite end of the tube, however, has a cross-sectionally enlarged portion which will consequently act as a skull on the anchoring tube, which prevents the anchoring tube from being passed completely through the anchoring hole and ensures that the anchoring unit is kept pressed against the ground. The anchoring unit further has a towing bracket in which one end of the railing is attachable.
    This overall inventive concept can be modified and varied in many different ways within the scope of the appended claims.
    In accordance with the invention, pipes are used to anchor the road barrier in the ground. Tubes are advantageous in that they have a high strength and large surface area in relation to their material content and weight. In the following exemplary embodiments, the pipe has a circular cross-section, but pipes with other cross-sectional shapes, such as square ones, could also be conceivable. The cross-sectionally enlarged portion at one end of the anchoring tube, which acts as a skull, has the shape of a flange extending along portions of the circumference of the tube. It should be understood, however, that the cross-sectionally enlarged portion could also have many other designs and all designs that can prevent the pipe from being passed completely through the anchoring hole may come into question.
    In accordance with the invention, it is intended that the anchoring pipe is driven into the ground. The term "drive down" is to be interpreted broadly and includes all procedures where the pipe is driven down without prior drilling or digging, such as by means of a large weight or by striking by means of a fall hammer or pile crane. There are essentially two ways to drive down the anchor pipe. Secondly, to drive it down when a filling body, ie a body which substantially completely fills the inner course of the pipe, is placed in the pipe. This method is used in difficult ground conditions, with for example a lot of stone, and the filling body will protect the pipe from upsetting during the pressing down. After the impact, the filling body is pulled up out of the pipe and the inner run of the pipe will then be empty and free of soil material but can be refilled with, for example, soil or concrete. When the anchoring pipe is driven down without any filling body in the pipe, which can be carried out when the soil conditions so allow, the soil material will, on the other hand, be pressed into the anchoring pipe and thereby contribute to the anchoring of the pipe. The anchoring unit can also be designed in many different ways. In the embodiment shown and described, the anchoring unit has the shape of a box with decreasing height in the direction from the handrail and the anchoring holes are accommodated in the bottom of the box. As a result, the cross-sectional enlarged portions of the anchoring tubes can be hidden inside the box, which after performing anchoring is provided with a lid. In the embodiment shown, the anchoring unit is provided with two anchoring holes. It should be understood, however, that anchoring units of different sizes and different numbers of anchoring holes may be provided depending on the anchoring forces desired to be achieved.
    In the embodiment shown, a road railing is anchored which has a railing beam with a substantially rectangular cross-section. Consequently, the anchoring unit is provided with a towing bracket which fits this type of road barrier. It should be understood, however, that the design of the drawbar can be adapted to many other types of road railings, such as road railings of profiled sheet metal or wire railings. It should further be understood that the railing anchorage does not absolutely have to be placed at a railing end, but it may be conceivable to make railing anchorages at very long road railings also in other places along the length of the railing by making branches or joints on the road railing.
    Brief Description of the Drawings An exemplary embodiment of the invention will hereinafter be described with reference to the drawings, in which: Fig. 1 is a perspective view of an anchoring unit and two anchoring tubes according to the invention; Fig. 2 shows a perspective view of an anchoring unit according to Fig. 1 connected to a road barrier and with the anchoring tubes partially inserted through the anchoring heel; Fig. 3 is a sectional side view of an anchorage according to the invention of a road rail end; and Fig. 4 is a schematic side view of a fall hammer assembly during striking of an anchor pipe through an anchor unit.
    Detailed description of an embodiment of the invention First reference is made to Fig. 1 in which an example of a rail anchorage according to the invention is shown comprising an anchoring unit 1 and two anchoring tubes 2. In the embodiment shown the anchoring unit is designed as an elongate carriage which has two side pieces 3, a bottom in the form of two separate bottom plates 4 and a detachable lid 5. At one of its short ends the anchoring unit has a towing bracket 6 which can be adapted for connection to a road railing of any kind. In the embodiment shown, the drawbar is in the form of a rectangular collar which is intended to be inserted into and connected to a rectangular railing beam of a road railing. At the same end as the drawbar, the anchoring unit has its greatest height, but this decreases continuously towards the opposite end so that the anchoring unit acquires a substantially pointed shape.
    The anchoring pipes 2 shown have a circular cross-sectional shape and can in a practical embodiment, for example, have a length of between 1-2 m and a diameter of between 15-20 cm. When anchoring a road barrier, the anchoring tubes are intended to be passed through anchoring heels 7 accommodated in the bottom plates 4 of the anchoring unit 10 and for this purpose one end of the anchoring tube and the main part of its longitudinal extension have a cross-sectional diameter of diameter diameter slightly smaller than the diameter of the anchoring tube. At the upper end of the respective anchoring tubes, however, these are provided with a cross-section enlarging portion, in the form of two flange portions 8, which will serve as a skull which prevents the anchoring tube from being completely passed through one of the anchoring holes 7.
    Next, reference is made to Figures 2 and 3, in which the connection of a railing anchor according to the invention to a road railing is shown. In the embodiment shown, the railing is in the form of a railing beam 9 with a rectangular cross-section, which is mounted at a distance above the ground on railing posts 10 which are intended to be partially lowered into the ground. Extending from the last railing post is a bent and downwardly sloping terminating part 11 of the railing beam, the outer end of which is connected to the towing bracket 6 of the anchoring unit, suitably by a bolt connection (not shown). The anchoring unit 1 is in turn intended to be located with an underside facing the ground and the anchoring pipes 2 driven through the anchoring holes and down into the ground, ie generally down the path.
    When the handrail is connected to the anchoring unit and this is anchored in the ground by pressing down the anchoring pipes, as illustrated in Fig. 3, a cover 5 is placed over the anchoring unit. As a result, the cross-sectional enlarged upper portions 8 of the respective anchoring pipes will be hidden in the box-shaped anchoring unit and the end of the handrail will also have a smooth transition with gradually decreasing height over the roadway, which is advantageous from a traffic safety point of view.
    Fig. 4 shows a possible approach for driving the anchoring pipes 2 through the anchoring holes 7 in the anchoring unit 1 and into the ground.
    This can be done, for example, by means of a schematically shown percussion device 12 which can optionally be carried on, for example, a truck, loader or excavator via a support arm 13. The percussion device comprises a support pillar 14 which is intended to support the ground during lowering during lowering and percussion assembly 15 which is displaceable upwards and downwards along the support column. A downwardly directed percussion mandrel 16 is carried in the lower part of the percussion unit and can be caused to strike downwards with great force by means of a hydraulic percussion mechanism (not shown). The lower part of the mandrel 16 consists of a filling body 17 with a circular cross-section which can be lowered into the inner course of the anchoring tube 2, while a striking collar 18, which is arranged immediately above the filling body, has a diameter larger than the anchoring tube so that when operating the impact mechanism will strike the upper end surface of the pipe and drive the pipe into the ground, as illustrated in the figure.
    A major advantage of the method according to the invention for anchoring railing ends is that no accurate measurement of the anchoring needs to be made in advance. Instead, a downwardly sloping terminating portion 11 of a railing beam is mounted after the last railing post, an anchoring unit 1 is connected to the outer end of the terminating railing member and then the required number of anchoring tubes 2 are driven down through the anchoring unit anchoring heel and into the ground until the anchoring tubes 8 the bottom parts of the anchoring unit. The railing anchorage can furthermore easily be adapted to the anchoring force required by using an anchoring unit which has the number of anchoring heels required for the dimensioning load.
