Definitions
- the present invention relates to installation means for installing a cover holder so as to be adjustable in height and inclination in order to keep a carriageway cover on top of an inspection shaft of an inspection manhole, comprising at least three threaded rods for adjusting the height and the inclination of the cover holder with respect to the inspection shaft.
- the present invention also relates to a method for installing a cover holder in order to keep a carriageway cover on top of an inspection shaft of an inspection manhole.
- the present invention relates to a method for adjusting an inspection manhole, in which a cover holder of a carriageway cover is installed on top of an inspection shaft by means of fastening means.
- inspection manholes are usually provided in order to give easy access to these pipes.
- Such inspection manholes usually comprise a vertically arranged inspection shaft which is connected to the subterranean pipes.
- an inspection shaft is a precast concrete element. With older inspection manholes, this shaft also used to be built from bricks.
- a cover plate is arranged on top of a concrete inspection shaft, having a (usually eccentric) opening, in order to allow an inspection hole to be connected to the inspection shaft in an eccentric manner.
- one or more (generally concrete) collars and/or one or more (generally concrete) adapters are arranged on this (eccentric) opening in order to bridge the difference in level between the cover plate and the ground level (often a carriageway).
- a cover holder with an access hatch is in turn fitted to the collars.
- the cover holder and the cover are usually made from cast iron.
- the inspection shaft and pipes situated below ground are made accessible by removing or pivoting the cover. Via this inspection manhole, people and/or tools can be brought into the underground pipes for inspection and/or maintenance purposes, etc.
- the present invention more specifically relates to such inspection manholes in which the cover is a carriageway cover which is arranged in the plane of a carriageway.
- Such covers are subject to different variable loads from, inter alia, the traffic which travels on the carriageway.
- Such carriageway covers and their positioning usually have to be able to withstand up to 40 tonnes.
- US 5,165,819 A describes a system by means of which the height of a carriageway cover is adjustable in steps.
- This system comprises trapezoidal coupling elements on the cover holder which are inserted in slots in a mounting ring in order to install the cover holder on top of the inspection shaft.
- the slots are arranged at equal distances from one another.
- This solution is a solution which has the same drawbacks that are associated with the use of collars and have been described in general above. In order to fit a carriageway cover at an inclination with respect to the inspection shaft, a different cover holder has to be used.
- CA 2 778 146 Al describes a system in which the adjustability by means of support elements of this kind, which are supported by a mounting ring and on which the cover holder is supported, can be carried out with greater accuracy.
- the separate support elements are spacer blocks which can be shortened to the desired level. If a different level is required, the spacer blocks can either be shortened further or new or additional spacer blocks can be used to reach the desired level. Measuring and adjusting the spacer blocks is a relatively laborious process. If new blocks are required during readjustment, these have to be available. If the height of the blocks needs to be adjusted, the necessary tools have to be available.
- the height and the inclination of the cover holder can be adjusted in a less complicated manner. This is achieved by means of adjusting screws which are used to laterally fix the position of the cover holder with respect to a mounting ring in which the cover holder is telescopically movable. With loads of up to 40 tonnes, it is difficult to maintain the position of the cover holder using such lateral adjusting screws and the cover holder descends relatively quickly, and the position therefore has to be readjusted frequently with this solution.
- a similar solution with adjusting screws and similar drawbacks is known from NL 7 503 223 A.
- This object of the invention is achieved by providing installation means for installing a cover holder so as to be adjustable in height and in inclination in order to keep a carriageway cover on top of an inspection shaft of an inspection manhole, comprising at least three threaded rods for adjusting the height and the inclination of the cover holder with respect to the inspection shaft, with the installation means being adapted to arrange the threaded rods so as to be adjustable in height with respect to the inspection shaft and fixed in height under the cover holder, in order to allow the cover holder to rest on top of a first end of the threaded rods.
- the threaded rods By allowing the cover holder to rest on top of a first end of the threaded rods, the threaded rods can be fitted under the edge of the cover holder which defines the passage opening, and without further narrowing the passage opening. In this case, it is also possible to protect the threaded rods towards the outside the cover holder, if it is not desired to incorporate these into the materials to be applied around the cover holder in order to construct a carriageway.
- the threaded rods may then be accessible from the inner side of the cover holder for adjustment, so that the height and the inclination of the cover holder can be accurately adjusted several times.
- the height of the cover holder is not varied with respect to fixed-height threaded rods in order thus to adjust the height of the cover holder with respect to the inspection shaft, but the height of the threaded rods with respect to the inspection shaft is varied and the cover holder is able to rest on top of a first end of the threaded rods. This ensures that the position of the cover holder with respect to the inspection shaft set by means of the threaded rods can be kept stable for a long time and also under varying loads of up to 40 tonnes using limited means.
- At least four threaded rods are incorporated into the installation means in order to be able to realise the currently prescribed passage openings and to be able to absorb the varying loads in a robust manner.
- the installation means according to the present invention furthermore comprise a mounting ring, for fitting on top of the inspection shaft, this mounting ring comprising fastening means to which the threaded rods are attachable so as to be vertically displaceable, in order to arrange these so as to be vertically displaceable with respect to the inspection shaft and in which the cover holder is fittable in the mounting ring so as to be at least partly telescopic in order to install it above the inspection shaft.
- Such a mounting ring is a simple aid for arranging the installation means in situ, which will in addition also protect the threaded rods towards the outside so that they, being the adjustment means for adjusting the height and the inclination of the cover holder, will not become embedded in the materials from which the carriageway is being constructed which an inspection manhole, in which these installation means are accommodated, adjoins.
- Such a mounting ring preferably has a shape which substantially corresponds to the shape of the cover holder and the carriageway cover.
- this mounting ring is preferably also mainly circular.
- this mounting ring is preferably also mainly rectangular.
- Such a mounting ring is preferably made from concrete.
- the mounting ring comprises a bush for each threaded rod to allow the corresponding threaded rod to at least partly extend therein with its second end.
- a threaded rod is then vertically displaced with respect to the inspection shaft, it will then extend to a greater or lesser degree into this bush.
- such a bush may for example be made from metal and may be cast into the concrete when the mounting ring is being cast.
- the bush preferably comprises anchoring elements to keep the bush fixed in the concrete.
- anchoring elements may, for example, be configured as one or more flanges which extend into the concrete with respect to the periphery of the bush.
- the installation means according to the present invention comprise a nut for each threaded rod which can be rotatably fitted on the corresponding threaded rod, comprise at least one slide-blocking element for each threaded rod in order to prevent the nut from sliding with respect to the threaded rod and comprise at least one rotation-blocking element for each threaded rod to prevent the threaded rod from rotating.
- each such bush may, for example, comprise a blocking guide which extends in the height direction of the bush and each threaded rod may comprise said rotation-blocking element at its second end is fittable in the blocking guide of the corresponding bush in a guiding manner to prevent the threaded rod from rotating with respect to the bush.
- the bush may to this end be designed, for example, substantially in the shape of a beam, in which case the blocking guide is designed as an internal rib of the bush.
- the blocking guide is particularly easily achievable.
- the mounting ring may comprise a step on its inner wall, in which case said bushes end in said step, and in which case at least some of said slide-blocking elements are arranged on this step above the corresponding bushes.
- the slide-blocking elements may in this case comprise a washer for each threaded rod which can be arranged around the threaded rod, between the nut and the step, and comprise a bracket which can be positioned around the threaded rod and above the nut and can be fastened to the washer and the step.
- the mounting ring is made of concrete in order to be able to pass on the forces occurring between the corresponding threaded rod, the corresponding nut and the mounting ring.
- This washer does not necessarily have to be in the form of a classic round washer, but may be configured as a plate-like element of any conceivable shape which is provided with an opening through which the threaded rod can extend and extends over the edge of the step in order to be able to engage this step.
- the part which extends over the edge of the step is preferably sufficiently large to be able to fasten the bracket to said washer and the step.
- each threaded rod is preferably spherical and the installation means preferably comprise a cup element for each threaded rod, which cup element is fittable below the cover holder or forms part thereof, in which case each cup element comprises a concave shape which can support the spherical end of the corresponding threaded rod herein in order to support the cover holder on top of this end of the threaded rod.
- the curvature of the spherical end preferably has a smaller diameter at each corresponding point than the curvature of the concave cup in order to allow optimum transmission of forces, without the spherical end becoming stuck in the concave cup.
- Such a cup element is preferably made from stainless steel.
- each threaded rod in such embodiments comprises a bore
- each cup element comprises a corresponding bore having a larger diameter than the bore in the corresponding threaded rod
- the installation means comprise a screw for each threaded rod with a screw head which has a larger diameter than the bore in the cup element, so that this screw is fittable with play in the bore in the corresponding cup element and is screwable into the bore of the threaded rod.
- the threaded rods cannot sink with respect to the cover holder and the set height and inclination of the cover holder are ensured for a long time.
- the object of the present invention is also achieved by providing an inspection manhole, comprising an inspection shaft, a cover holder and fastening means for fastening the cover holder on top of the inspection shaft, in which case these fastening means are configured as installation means according to the present invention as described above.
- the object of the present invention is also achieved by providing a method for installing a cover holder in order to keep a carriageway cover on top of an inspection shaft of an inspection manhole, in which the cover holder is installed on top of the inspection shaft by means of above-described installation means according to the present invention.
- the cover holder is first fitted on top of the inspection shaft by means of the installation means, in which case the threaded rods are in a position in which they are raisable with respect to the inspection shaft. Subsequently, the cover holder is jacked up with respect to the inspection shaft by means of a jack until it reaches the desired height and the threaded rods are then raised until the cover holder rests on top of the first end of the threaded rods and the jack can be removed.
- the threaded rods are not subjected to unnecessary loads during the vertical displacement of the cover holder, but are only subjected to loads when setting the correct height and inclination of the cover holder.
- the object of the present invention is also achieved by providing a method for adjusting an inspection manhole, in which a cover holder of a carriageway cover is fitted on top of an inspection shaft by means of fastening means, comprising:
- Fig. 1 shows an inspection manhole in perspective
- FIG. 2 shows an embodiment of installation means according to the present invention with a cover holder and carriageway cover installed thereon in cross section;
- Fig. 3 shows the cover holder and the carriageway cover from Fig. 2, in which the cup elements of the installation means from Fig. 2 are attached to the cover holder, in perspective view;
- Fig. 4 shows a bush, washer, nut, bracket and threaded rod of the installation means from Fig. 2 in perspective view;
- Fig. 5 shows a threaded rod of the installation means from Fig. 2 in perspective view
- FIG. 6 shows the threaded rod from Fig. 5 in top view
- Fig. 7 shows a cup element of the installation means from Fig. 2 in perspective, with a holding element fitted thereon;
- Fig. 8 shows the installation means from Fig. 2 in perspective, without the cup elements
- Figs 9 to 12 diagrammatically show in partial view and partial cross section in successive steps how a carriageway incorporating a carriageway cover of an inspection manhole can be laid according to the invention, and with an inspection manhole according to the present invention.
- the illustrated inspection manholes (1) in each case comprise an inspection shaft (2) which is connected to sewage pipes (23) which extend underground (see Figs 1 and 9-12). Over this inspection shaft (2), a cover plate (7) is fitted which comprises an eccentric opening on which a mounting ring (6) with installation means according to the present invention is provided. A cover holder (5) is fitted in this mounting ring (6) so as to be telescopically displaceable. In the cover holder (5), a carriageway cover (3) is held.
- the inspection shaft (2), the mounting ring (6) and the cover holder (5) are substantially cylindrical and the carriageway cover (3) is essentially circular.
- these elements could also be of a different shape.
- the inspection shaft (2) and the mounting ring (6) are prefab concrete elements. These could optionally also be made from other suitable materials.
- the cover holder (5) and the cover (3) are made from cast iron. These could optionally also be made from other suitable materials.
- four threaded rods (4) are provided which are arranged at equal distances from each other under the cover holder (5).
- the inner wall of the mounting ring (6) is stepped.
- the inner wall of the mounting ring (6) is essentially formed in two cylindrical parts, in which case the lower part of the mounting ring (6) has a smaller inner diameter than the upper part of the mounting ring (6).
- the mounting ring (6) comprises an essentially horizontal step (24) between both parts (lower and upper).
- the bushes (8) end in this step from the underside of which in each case one threaded rod (4) extends partly into the former.
- the bushes (8) are hollow and have a square cross section along essentially their entire length.
- these bushes (8) comprise a metal flange (13) which is welded to the sleeve of the bush (8).
- These bushes (8) are cast into the concrete of the mounting ring (6) and are anchored therein by means of this flange (13).
- a stick (26) is welded onto the underside of each threaded rod (4) and extends radially with respect to the axis of the threaded rod (4), as can be seen in Figs 5 and 6.
- this stick (26) extends as far as an inner rib of the bush (8) as a rotation-blocking element (26). In this way, the threaded rod (4) can be vertically adjusted in the corresponding bush (8), but cannot be rotated in this bush (8).
- a metal washer (10) is welded onto the top of the bush (8).
- a nut (11) is fitted on this washer (10), around the threaded rod (4).
- a metal bracket (9) is in turn fitted on the washer (10) and the nut (11).
- an opening is provided with a slightly larger diameter than the diameter of the threaded rod (4), so that the threaded rod (4) can extend freely therethrough.
- the bracket (9) is then fastened to the washer (10) by means of bolts (20). Both the bracket (9) and the washer (10) comprise bores which are adapted to this end.
- the nut (11) extends between the washer (10) and the bracket (9), as can be seen in Fig. 4. In this way, the nut (11) cannot be vertically displaced.
- the corresponding threaded rod (4) can then be vertically displaced in the bush (8) and thus with respect to the mounting ring (6).
- the upper end (14) of the threaded rods (4) is spherical, as can be seen in Figs 4 and 5.
- Four corresponding stainless-steel cup elements (16) are in turn fastened to the underside of the cover holder (5) by means of bolts (10), as can clearly be seen in Fig. 3.
- the cover holder (5) and the cover (3) may be standard elements. In this case, bores will first be made in the cover holder (5) so as to be able to fasten these cup elements (16) thereto.
- cup elements (16) comprise concave cups having a concave shape which corresponds to the spherical shape of the upper ends (14) of the threaded rods (4), as can be seen in Fig. 2, so that the threaded rods (4) can be accommodated in these cups by their spherical end (14) and the occurring forces can then be transferred between the threaded rods (4) and the cup elements (16) in an optimum manner.
- each threaded rod (4) is provided with a bore (15) in its spherical end.
- the corresponding cup element (16) is provided with a bore of a slightly larger diameter.
- a screw (17) can be fitted through the bore in the cup element (16), as can be seen in Fig. 7, and can be screwed into the corresponding threaded rod (4), as can be seen in Fig. 2.
- the screw (17) has a screw head with a diameter which is greater than the diameter of the bore in the cup element (16).
- the screw can be displaced in this bore with some play.
- the cover holder (5) can be fastened to the threaded rods (4) via the cup elements (16), in which case an adjustment of the inclination of the cover holder (5) with respect to the threaded rods (4) is still possible.
- a holding element (18) is fastened to the cup element (16) by means of bolts (19) in order to prevent this screw (17) from becoming loose on account of, for example, vibrations.
- a carriageway cover (3) can be incorporated in a carriageway comprising several layers of asphalt (28, 29) by means of the installation means according to the present invention using a method according to the present invention.
- a carriageway cover (3) in other types of carriageways with the same advantages regarding adjustability in height and inclination of the cover holder (5) with respect to the inspection shaft (2) on top of which it is arranged. Only the construction of a carriageway comprising several layers of asphalt (28, 29) will be discussed in more detail here, because the installation means according to the present invention offer additional advantages with this method.
- the mounting ring (6) is fitted on top of the inspection shaft (2) as soon as this has been put in place. This may be effected by arranging this mounting ring (6) on a bed of mortar on the cover plate (7) on top of the inspection shaft (2).
- the inspection shaft (2) may, for example, be prefabricated and have a height which is the difference between the level of the carriageway and the level of the sewage pipes (23) to which it is to be connected, minus a certain height for placing the mounting ring (6), the cover holder (5) and the cover (3). If this is not the case and the deviation is much greater than the height required for placing the mounting ring (6), the cover holder (5) and the cover (3), the mounting ring (6) could also be concreted, for example in situ on top of the cover plate (7) by means of suitable shuttering.
- cover holder (5) and the cover (3) may also be fastened to the mounting ring (6) in situ by means of the other installation means. This will be the case, for example, if the fastening means at an existing inspection manhole (1) are to be replaced by the installation means according to the present invention.
- the existing cover holder (5) with the existing cover (3) will first of all be retrieved, at least a part of the means by which the cover holder (5) was installed on top of the inspection shaft (2) will be removed, the mounting ring (6) with the threaded rods (4) and the cup elements fitted thereon (preferably all other installation means are already fastened to the mounting ring) will be installed on top of the inspection shaft (2), holes will be drilled in the retrieved cover holder (5) and the cup elements (16) will be fastened thereto.
- the inspection manhole (1) is closed off immediately by the final carriageway cover (3). Materials, such as soil or stones, can no longer end up in the inspection shaft (2) during the entire duration of the construction of the superstructure.
- the threaded rods (4) are preferably initially at such a level that the cover holder (5) and the carriageway cover (3) are situated just below the layers of asphalt (28, 29) to be laid.
- the slots are filled, the caissons are made and the road metal foundations (27) are laid.
- the road metal (27) around the mounting ring (6) is permanent. It does not have to be loosened again in order to adjust the carriageway cover (3). With this construction, no foundation materials (27) end up in the inspection shaft (2).
- the inspection shaft (2) does remain accessible at all times by opening the carriageway cover (3).
- the centre of the carriageway cover (3) is determined and subsequently the bottom layer of asphalt (28) and the top layer of asphalt (29) are laid on top of the carriageway cover (3), as can be seen in Fig. 9.
- the person laying the asphalt (29) therefore does not have to take the carriageway cover (3) into account.
- the machine can be driven across the carriageway cover (3). There is thus no manual labour required in the vicinity of the carriageway cover (3) which could result in bumps in the finish.
- Both the bottom layer (28) and the top layer (29) can be laid completely mechanically, resulting in the correct finishing thickness. This also leads to a significant improvement in the quality of the asphalt pavement.
- the diameter of the carriageway cover (3) is plotted and a bore is used to drill an opening which is made approximately 5 centimetres larger than the carriageway cover (3), so that the drilled opening ends on top of the mounting ring (6), as can be seen in Fig. 10.
- the opening which is made for adjusting the height and the inclination of the carriageway cover (3) with respect to the carriageway can be kept quite small.
- the foundation of the carriageway around the mounting ring (6) is no longer loosened and does not have to be replaced by rich concrete, as a result of which there will be no differences in curing.
- the mounting ring (6) itself is also bevelled with a bevelled edge (25) at the top (see Fig. 2) in order to further minimize possible differences in expansion.
- This may be carried out, for example, if a further compaction of the asphalt and/or the foundation has taken place after x number of years.
- the liquid asphalt (30) is drilled out or hacked away, the height and/or the inclination of the carriageway cover (3) is adjusted and the opening around the carriageway cover (3) is filled up again with liquid asphalt (30).
- the carriageway cover (3) is first lowered.
- the top layer of asphalt (29) on top of the carriageway cover (3) is cut away, the top layer (29) is replaced and an opening is subsequently produced once again around the carriageway cover (3), as has been described above, the carriageway cover (3) is raised again and placed at the correct inclination and the opening next to the carriageway cover (3) is filled again with liquid asphalt (30).
