Definitions
- the invention relates to a road cap, in particular for the top closure of access shafts to shut-off devices on lines laid under roads, to survey points o.
- Such street caps usually have a shaft - shaped housing, which through the street in the Road substructure is enough and closed with a lid at the top is.
- the housing be in two parts to produce as a tube-in-tube version, what the digging would save. However, the determination is then made again by relining.
- FR-A-2 125 787 is a street cap according to the preamble of claim 1 known.
- the object of the invention is a road cap of the beginning mentioned type to create a simplified level setting allows.
- a method of insertion is also intended and adjusting the level of such a road cap be created.
- the housing has an external thread on its outer surface which directly engages the road material, it can be adjusted by turning it. To do this in the upper part of the attack for a screwing device provided, for example recesses in one upper collar of the housing into the shovel of a pickaxe can intervene. The pickaxe or pimple then works with its shovel as a wrench, while the stem allows a great leverage.
- the housing of the screw cap usually ranges from the gravel bed of the road base, in which it is inserted, through the HMT up to the top Wear or top layer, if provided.
- the driving projections that fit into the recesses secure the lid in the Housing against twisting. It is thus possible to twist the whole Make housing for adjustment by attacking a tool on the lid.
- Threads in the various axial areas as well Interruption in the axial and / or circumferential direction of the thread to adapt to these different conditions.
- changing the external adhesive properties for example by applying release agents, the thread and the rest of the outer surface of the housing affect that the desired stiff screw action is possible.
- Different slip especially in loose materials, such as the gravel bed, can occur for example by different thread heights and / or Thread pitch encountered in the different areas become.
- the housing of the street cap can be threaded into it Gravel bed used to be the road.
- the HMT are applied and rolled, the roller also over the road cap drives away. If necessary, she will be with her Thread in the gravel bed pressed down, but because of the then displaceable structure of the gravel bed is possible is. Nevertheless, there is a form-fitting intervention so that the level of the top edge of the housing of the road cap Screw adjustment can still be readjusted.
- a wear surface layer is applied, which is at least a few centimeters is thick, the street cap can now be adjusted by screwing be brought to the new level without bigger ones Excavation or mortising work is necessary. At most it can loosening in the area of the top layer become.
- Fig. 1 shows the structure of a street in vertical section.
- a supply line for example laid a gas or water pipe 12.
- a gate valve 13 is arranged, which has an upward extended actuating rod 14 by means of a square 15 and one for actuation, not shown Key can be turned.
- the actuating rod is surrounded by a protective tube 16, that protrudes from the slider and, like that Operating rod, some distance from the road surface 17 ends. It protrudes into a street cap 18 into it, which is a tubular, circular cylindrical or light has conical housing 10, which from the road surface 17 protrudes down, while the protective tube 16 over a part surrounds its height and upwards through a lid 25 (see Fig. 3) can be closed.
- the road cap forms thus a chamber 19 free of the road surface and the ground, through which the slide 13 can be actuated becomes. This free chamber 19 can go down to the ground with a cylindrical, pot-like end part closed a hole in the bottom of the protective tube become.
- the final part can be made of any material, e.g. also from Plastic. You could also do it like a bellows train that set on the protective tube or on the housing and compensates for axial movements due to its flexibility. It is also possible to have a corresponding covenant to form the protective tube that connects to the inside of the housing 10 cooperates.
- the housing 10 of the road cap 18 has an axial, i.e. vertical extension of e.g. 30 cm to 40 cm and one Diameter between e.g. 15 cm and 20 cm, preferably approx. 17 cm. With a normal road construction, it protrudes through the upper road surface or wear layer 20 and through the underlying hot-mix base layer 21 into the gravel bed 22 into it.
- the gravel bed consists of gravel, crushed stone and / or sand and the hot mix base is a bituminous such gravel, while the upper wear layer one similar structure, but with greater attention to the surface, their wear and slip behavior etc. The Thicknesses of these layers are also different.
- the wear layer is usually 3 cm to 5 cm thick
- the hot mix base layer is 7 cm to 12 cm
- the gravel layer 50 cm to 100 cm thick are usually 3 cm to 5 cm thick
- the housing 10 of the road cap 18 consists of a essential cylindrical tube made of cast iron or a other material that is at least satisfactory Corrosion behavior has good strength. While it is on the inside is essentially smooth-walled and only in Distance from the upper end edge 23 an inwardly projecting Has collar 24 on which the one shown in Fig. 3 Cover 25 with its outer flanges 26 is on a thread 27 is provided on the outside of the road cap 18. As a variant, the inside could also be threaded be carried out so that the externally threaded End part can be screwed.
- the example shown in FIG. 1 is a fine thread with a round profile that is single or multi-start can be trained.
- Threads 28, i.e. which over the essentially cylindrical Thread base 29 protruding, helical Thread projections have an axially shorter length than that Intermediate sections of the thread base.
- This Thread is suitable e.g. for gravel-sand subsoil.
- Thread forms may be suitable.
- a taper in the outer thread diameter can, especially to adapt to soil conditions, Bring benefits. It is also possible to get one Threads of the same or a different material as that Pull the housing onto the housing body.
- the distance of the federal 24 from the top End face 23 of the housing 10 is such that it is approximately the thickness corresponds to the flange 26 of the cover or, preferably, is slightly larger. So in the closed state the street cap flush with or one to a few millimeters under the road surface 17.
- the lid 25 can also be made of cast iron or others Materials.
- Fig. 4 corresponds to in all details that described in Fig. 1.
- the thread on the outer circumference is partially interrupted, to self-locking when installed promote. Sand and gravel particles can then enter the gaps 32 penetrate the threads and the road cap make it so stiff that they are under traffic and vibrations cannot turn by itself.
- Thread 27 is also provided. While in the upper area, the predominantly in the bituminous Layers (HMT 21 and / or top layer 20) Thread 27 is provided with a relatively low thread height, is in the lower part, mainly in the gravel bed Thread 27a provided with higher threads. Between there is a thread-free section 33 You can use these different sections higher or lower thread heights, unthreaded sections and / or threads of different pitch or different interruption of the threads (see Fig. 4) in any desired combination on the axial The length of the street cap must be distributed. 5 is also the lower edge 34 of the road cap on one side (or in Fig. 6: on both sides) beveled so that they Screw movement can penetrate the ground more easily.
- the Threads can also have asymmetrical flanks, in that the lower flank is flatter than the upper.
- the hot mix base layer (HMT) 21 is poured over it. Then the road caps 18 are exposed and can now can be adjusted to the desired height by turning. To grabs the road worker with one at every road construction site existing tool, namely a pickaxe or a pimple 35, with its flat side (scoop) 36 into the slots 30 which, as shown in FIG. 2, several times on Scope are provided, e.g. in a four-way arrangement (Fig. 1).
- the setting can be made so that the top edge is still well below the top of the HMT 21, so that a road roller can drive over it without hesitation. Self if she pushes down the road cap 18 further than she does was preset, this is in the still warm layer and possible in the gravel bed.
- the street cap according to the invention enables it, its upper edge, which may also be on the upper end face 23 are overlapped by the outer flange of the cover could adjust to the correct height so that in each Condition of use, i.e. with and without top layer 20, always the correct height is available. This can be done without much digging and cumbersome adjustment and relining work happen by simply turning the street cap. If, due to any circumstances, it is too tight, then so A warming up of the cap itself or is usually sufficient their surroundings to make them rotatable. Your interior 19 can be quickly heated, for example, with a burner and thus the one immediately adjacent to the thread Bitumen mass to be heated so that the road cap turns easily.
- bitumen layer in the Condition of use cold and therefore hard and also relatively good is sticky, self-adhesion or stiffness in the Condition of use reached.
- the cast housing 10 has on its outside a thread 27 with trapezoidal flanks.
- the threads 28, i.e. the elevations above the thread base 29 are in axial direction much shorter than the corresponding groove base.
- the inner collar 24b in the upper Housing section has slots or recesses 30b, the with the central opening 31 in the collar through connecting recesses 42 are connected. They are two opposite, lenticular slots provided on one side, the each through a recess 42 with the opening 31 in Connection, the width of which is about half as large as that Length of the slots 30b. This makes it more sensitive to breakage Avoid web between the slots and the opening 31 and it is possible to use an even greater variety of tools Turn the street cap on. For example also a pimple shovel that is wider than the length of the Slots 30b, are made by slanting through the Recess through 42.
- FIG. 6 and 8 to 10 show the lid 25. It is made also from a cast iron part, which is the basic shape of a round disc. Its top is in accordance with FIG. 9 with a network of grooves 44 and with correspondingly cast-in Designations 45, e.g. Provided "water”. Further a handling slot 46 is cast in the middle. 10, it has approximately the shape of a Semicircle with approximately hub-shaped protruding into the slot Projections 47, however, not entirely the slot bridged. They form a narrower between them Slot 48. The one to be seen in particular from FIG.
- the shape of the slot 46 has a simple manufacture as a casting with an easily demoldable and good in the Shape durable core has the advantage that the two protrusions do not form a bridge that completely protrudes the slot is at risk of breakage. Furthermore, a tool can both Lift the lid under the projections, for example a pimple tip, as well as a pimple shovel that fits into the narrower gap 48 for rotating the cover. Furthermore, due to the shape, it is easily possible foreign bodies, e.g. ice in winter, to remove.
- the upper disc-shaped section 49 of the cover is on its outer periphery has a downwardly projecting edge 50 which rests on the upper surface of the collar 24b.
- a gap 53 is provided, which is a not insignificant distance between the The outer circumference of the cover plate 49 and the edge 52 creates. This will cause the cover to rust in the housing avoided.
- the gap can be full of sand or dirt set, but easy to remove when opening the lid is.
- the lid only lies with the lower surface of the Edge 50 on the collar 24b where rusting does not occur fear or no permanent blocking of the lid can cause.
- the gap 53 is ensured that one of the Disc protruding downward, the central area of the Lid surrounding ring edge 55 is provided, which with the Inner circumference of the collar 24b for centering the cover interacts in the housing. Furthermore, this ring edge 55 two mutually opposite points projecting outwards Carriage protrusions 56, which in the recesses 42nd fit in and the lid in the housing against twisting to back up. It is thus possible to twist the whole Housing for setting also by attacking a tool on the lid, for example inserting a pick shovel in to make the slot 46, 48. Especially during the Road construction itself, e.g. when applying the hot mix base layer, the lid can therefore remain closed to to avoid filling the shaft surrounded by the housing and it can then be done without removing the Cover setting the road cap to the correct one Height can be made by screw movement.
