Description

Die Erfindung betrifft gemäß dem Oberbegriff von Anspruch 1 einen Straßenaufsatz.The invention relates according to the preamble of claim 1 a street tower.

Straßenaufsätze dienen dem Verschließen von Schächten und bestehen aus einem Rahmen und einem Verschlusselement. Zum Einsatz kommen Straßenaufsätze beispielsweise im Straßenbau als rechteckige, quadratische und runde Ausführungen zur Verwendung in der Fahrbahn oder aber am Fahrbahnrand und hier insbesondere auch angrenzend an einen Gehweg. Sie können aber auch in Lagerhallen, Parkflächen und ähnlichem Verwendung finden.Road tops are used to close shafts and consist of a frame and a closure element. Road mats are used, for example, in road construction as rectangular, square and round designs for use in the roadway or at the edge of the road and in particular also adjacent to a walkway. But they can also be found in warehouses, parking areas and the like.

Je nach Anforderung hat die Oberfläche des Verschlusselements eine Pultform, eine Rinnenform oder eine Muldenform. In einer am Fahrbahnrand angeordneten Wasserrinne kommen bevorzugt rechteckige Straßenaufsätze mit Pultform zum Einsatz, sodass Rinne und Straßenaufsatz bündig abschließen. Rinnenförmige Straßenaufsätze sind vorteilhaft in einer vertieften Rinne, in die das Oberflächenwasser in Richtung des Schachtes strömt. Um den Durchtritt von Wasser oder einem anderen Medium zu ermöglichen, weisen die Verschlusselemente Schlitze auf, weswegen sie auch als Rost bezeichnet werden.Depending on the requirement, the surface of the closure element has a desk shape, a gutter shape or a trough shape. In a arranged on the edge of the road gutter are preferably rectangular street essays with desk shape used so that the gutter and street essay flush. Trough-shaped roadside attachments are advantageous in a recessed channel, into which the surface water flows in the direction of the shaft. In order to allow the passage of water or other medium, the closure elements have slots, which is why they are also referred to as rust.

Insbesondere im Straßenbau und auch in Lagerhallen werden das Verschlusselement, der Rahmen und auch der Schacht durch hohe und regelmäßig auftretende Kräfte durch Überfahrten von Fahrzeugen belastet. Problematisch hierbei ist, dass der Schacht diese Kräfte häufig nicht dauerhaft aufnehmen kann und beschädigt wird. In der Folge wird der Rahmen, der das Verschlusselement aufnimmt, nicht mehr ausreichend vom Schacht gestützt und es kommt zu Setzungsschäden. Bei diesen sinkt der Rahmen in dem umgebenden Material, z.B. Asphalt, ein. Die Fahrbahn wird folglich uneben und überstehender Asphalt ist anfällig für mechanische Belastungen, sodass hier Asphaltstücke herausbrechen können. Zudem kann Wasser zwischen dem Rahmen und dem Asphalt eindringen und im Winter zu zusätzlichen Frostschäden führen.In particular, in road construction and in warehouses, the closure element, the frame and the shaft are burdened by high and regularly occurring forces by crossings of vehicles. The problem here is that the shaft often can not absorb these forces permanently and is damaged. As a result, the framework that becomes the Closing element receives, no longer sufficiently supported by the shaft and it comes to subsidence damage. In these, the frame sinks in the surrounding material, eg asphalt. As a result, the road surface becomes uneven and overhanging asphalt is susceptible to mechanical stress, so that pieces of asphalt can break out here. In addition, water can penetrate between the frame and the asphalt and cause additional frost damage in winter.

Kritisch verhalten sich auch Straßenaufsätze, die nicht vollständig von einem einzigen Material umgeben sind. Insbesondere sind hier die Straßenaufsätze im Rinnstein oder am Fahrbahnrand zu nennen. Diese werden meist auf einer Seite von Asphalt, auf zwei Seiten von Rinnsteinen und auf der vierten Seite von Bordstein oder Bankett umgeben. Aufgrund der unterschiedlichen Stützkraft der unterschiedlichen Materialien, z.B. auch aufgrund unterschiedlicher Verdichtung, können derartige Straßenaufsätze durch die auftretenden Belastungen kippen.Street essays that are not completely surrounded by a single material are also critical. In particular, here are the street essays in the gutter or at the edge of the road to call. These are usually surrounded on one side by asphalt, on two sides by gutters and on the fourth side by curb or banquet. Due to the different support force of the different materials, e.g. also due to different compression, such road surfaces can tilt by the loads occurring.

DE 203 174 83 U1 beschreibt beispielsweise einen Straßenaufsatz mit einem auf einer Schachtöffnung anbringbaren Rahmen und mit einem darin einsetzbaren Verschlusselement, welches sich eingesetzt über die Schachtöffnung erstreckt und auf Auflageflächen am Rahmen aufliegt. Ein solcher hat den beschriebenen Nachteil der mangelhaften Stützung und neigt zum Beispiel dazu zum Bordstein hin zu kippen. DE 203 174 83 U1 describes, for example, a road attachment with an attachable to a shaft opening frame and with a usable therein closure element, which extends over the shaft opening and rests on bearing surfaces on the frame. Such has the described disadvantage of poor support and tends, for example, to tip to the curb.

Um die Krafteintragung vom Straßenaufsatz auf den Schacht zu verbessern sind aus dem Stand der Technik verschiedene Lösungen bekannt.In order to improve the force entry from the road attachment to the shaft, various solutions are known from the prior art.

So offenbart DE 903 00 698 T2 ein Verfahren zum Austausch eines Schachtrahmens, bei dem ein halbkugelförmiger Abschnitt einer befestigten Straße rund um den Schachtrahmen ausgeschnitten wird. Zur Verstärkung kann in dem Füllstoff ein Eisenstangennetz angeordnet sein. Auf diese Weise wird der Schachtrahmen besser gestützt. Ein Eisenstangennetz eignet sich jedoch ausschließlich für abbindende Umgebungsmaterialien wie Asphalt, Mörtel oder Beton. In nicht abbindenden Materialien sinkt die Bewehrung schnell ein und bietet wenig Halt.So revealed DE 903 00 698 T2 a method of replacing a manhole frame in which a hemispherical portion of a paved road is cut around the manhole frame. For reinforcement, an iron rod net can be arranged in the filler. In this way, the manhole frame is better supported. However, an iron bar net is only suitable for bonding ambient materials such as asphalt, mortar or concrete. In non-setting materials, the reinforcement sinks quickly and offers little support.

DE 10 2004 053 188 A1 beschreibt einen Schachtrahmen, an dessen Außenseite im Abstand voneinander Laschen mit jeweils einem Loch angebracht sind. Durch diese Löcher werden Bewehrungs- oder Moniereisen eingesetzt, mit denen der Schachtrahmen in einer Betonmasse verankerbar ist. Auch eine solche Bewehrung eignet sich ausschließlich für abbindende Umgebungsmaterialien wie Asphalt, Mörtel oder Beton. In nicht abbindenden Materialien sinkt die Bewehrung schnell ein und bietet wenig Halt. DE 10 2004 053 188 A1 describes a manhole frame, on the outside of each other at a distance tabs are mounted, each with a hole. Through these holes reinforcing or Moni irons are used, with which the manhole frame is anchored in a concrete mass. Even such a reinforcement is only suitable for bonding ambient materials such as asphalt, mortar or concrete. In non-setting materials, the reinforcement sinks quickly and offers little support.

AT 37 919 E zeigt eine Abdeckung für ein rechteckiges Mann-Einstiegsloch, bei dem der Rahmen aus Aluminiumextrusionsteilen gefertigt ist. Diese Extrusionsteile weisen dabei bewehrungsähnliche Gestaltungsgeometrien auf, die zu einer verbesserten Anbindung im umgebenden Material führen. Eine derartige Abdeckung ist für Belastungen, wie sie im Straßenverkehr auftreten, nicht geeignet, da Aluminium zu leicht verformt und teuer ist. Zudem können hiermit nur eckige Rahmen gefertigt werden. AT 37 919 E shows a cover for a rectangular man-entry hole, wherein the frame is made of aluminum extrusion parts. These extrusions have reinforcement similar Design geometries that lead to an improved connection in the surrounding material. Such a cover is not suitable for loads such as those encountered on the road, since aluminum is too easily deformed and expensive. In addition, only square frames can be made hereby.

US 3 975 870 A beschreibt ebenfalls einen rechteckigen Rahmen aus Aluminiumextrusionsteilen. Zusätzlich sieht sie Zuganker vor, damit der Rahmen nicht aus dem umgebenden Material herausgezogen werden kann. Eine derartige Abdeckung ist für Belastungen wie sie im Straßenverkehr auftreten nicht geeignet, da Aluminium zu leicht verformt und teuer ist. Zudem können hiermit nur eckige Rahmen gefertigt werden. Die gezeigten Zuganker verhindern außerdem primär das Herausziehen und nicht das Einsinken in das Material. Ähnlich wie Bewehrungen eignen sich Zuganker eher für abbindende Umgebungsmaterialien, da sie ansonsten unter Belastung im Material langsam wandern können. US Pat. No. 3,975,870 also describes a rectangular frame of extruded aluminum parts. In addition, it provides tie rods, so that the frame can not be pulled out of the surrounding material. Such a cover is not suitable for loads such as those encountered on the road, since aluminum is too easily deformed and expensive. In addition, only square frames can be made hereby. The tie rods shown also prevent primarily pulling out and not sinking into the material. Similar to reinforcements, tie rods are more suitable for bonding environment materials, otherwise they can slowly migrate under load in the material.

Dahingegen zeigt DE 20 2005 012 306 U1 einen für den Straßenbau geeigneten Schachtrahmen, der mittels Zugankern vor dem Einsinken in das umgebende Material gesichert wird. Nachteilig ist ebenfalls, dass diese nur für abbindende Umgebungsmaterialien geeignet sind, da sie ansonsten unter Belastung im Material langsam wandern können.On the contrary shows DE 20 2005 012 306 U1 a suitable for roadway manhole frame, which is secured by tie rods before sinking into the surrounding material. Another disadvantage is that they are only suitable for setting ambient materials, since they can otherwise migrate slowly under load in the material.

Weiterhin ist aus der EP 1 182 299 A2 und DE 201 22 452 U1 eine runde Schachtabdeckung bekannt, die sich konisch verjüngende Seitenflächen aufweist. Die schrägen Seitenflächen stützen sich gemäß DE 201 22 452 U1 auf einer schrägen konischen Fräskante in der Trägerschicht von Straßenasphalt ab, sodass nicht die gesamten Belastungen von dem Schacht getragen wird, sondern ein Teil des Druckes von dem Asphalt aufgenommen wird. Zusätzlich kann ein Konusring mit den schrägen Seitenflächen korrespondieren und die Belastungen auf weiter außen liegende Bereiche übertragen. Schließlich zeigel die DE 102006 056 936 A1 ein Verfahren entsprechend dem Oberbegriff des Anspruch 1.Furthermore, from the EP 1 182 299 A2 and DE 201 22 452 U1 a round manhole cover known, which has conically tapered side surfaces. The oblique side surfaces are supported according to DE 201 22 452 U1 on an oblique conical milling edge in the carrier layer of road asphalt, so that not the entire burden is borne by the shaft, but a part of the pressure is absorbed by the asphalt. In addition, a conical ring can correspond with the oblique side surfaces and transfer the loads to areas that are further outside. Finally show the DE 102006 056 936 A1 a method according to the preamble of claim 1.

Nachteilig ist der Schachtabdeckung, dass diese aufgrund der runden Form nicht an allen Positionen einsetzbar ist, an denen Straßenaufsätze vorzusehen sind. Insbesondere kann eine derartige Schachtabdeckung nicht im Rinnstein eingesetzt werden.A disadvantage of the manhole cover is that it can not be used at all positions due to the round shape, on which street attachments are to be provided. In particular, such a manhole cover can not be used in the gutter.

Zusätzlich erhöht sich aufgrund der erforderlichen geometrischen Form das Gusseisenvolumen erheblich. Dies führt neben erhöhten Materialkosten wegen der hohen Materialstärke zu verlängerten Zykluszeiten bei der Materialabkühlung. Somit erhöhen sich die Herstellkosten.In addition, due to the required geometric shape, the cast iron volume increases significantly. This leads, in addition to increased material costs due to the high material strength to extended cycle times in the material cooling. Thus, the manufacturing costs increase.

Aufgabe der Erfindung ist, einen Straßenaufsatz zu entwickeln, der eine verbesserte Krafteinleitung in die Umgebung und eine lange, wartungsfreie Lebensdauer aufweist. Dabei sollte der Straßenaufsatz variabel entsprechend der vorgesehenen Einsatzposition gestaltbar sein. Weiterhin sollen die Fertigungs- und Materialkosten für eine derartige Schachtabdeckung die bisherigen nicht wesentlich übersteigen und die spätere Montage einfach handhabbar sein.The object of the invention is to develop a street tower, which has an improved force introduction into the environment and a long, maintenance-free life. In this case, the street tower should be variably designed according to the intended use position. Farther should the production and material costs for such a manhole cover the previous not significantly exceed and later assembly be easy to handle.

Hauptmerkmale der Erfindung sind im kennzeichnenden Teil von Anspruch 1 angegeben. Ausgestaltungen sind Gegenstand der Ansprüche 2 bis 5.Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 5.

Die Erfindung betrifft einen Straßenaufsatz für einen Schacht, bestehend aus einem runden oder eckigen Verschlusselement und einem Rahmen, wobei der Straßenaufsatz eine Pultform, eine Rinnenform oder eine Muldenform hat, wobei der Rahmen zweiteilig aus einer Gussaufnahme zur Aufnahme des Verschlusselements und einem Betonstützkörper ausgebildet ist, wobei der Betonstützkörper und die Gussaufnahme an einer Seite form- und stoffschlüssig miteinander verbunden sind, die Gussaufnahme den Betonstützkörper in Richtung des Verschlusselements überragt, und der Betonstützkörper eine sich nach unten verjüngende äußere Seitenfläche hat.The invention relates to a road attachment for a shaft, comprising a round or square closure element and a frame, wherein the road attachment has a desk shape, a gutter shape or a trough shape, wherein the frame is formed in two parts from a casting receptacle for receiving the closure element and a concrete support body, wherein the concrete support body and the cast receptacle are connected to one another in a positive and cohesive manner on one side, the cast receptacle projects beyond the concrete support body in the direction of the closure element, and the concrete support body has an outer side surface tapering downwards.

Hierdurch ergeben sich zahlreiche Vorteile. Mittels der sich nach unten verjüngenden äußeren Seitenfläche des Betonstützkörpers erfolgt ein deutlich verbesserter Lastabtrag vom Rahmen auf das umgebende Material. Insbesondere wird so auch der unter dem Straßenaufsatz befindliche Schacht geschützt, dessen Lebensdauer sich hierdurch verlängert. Zusätzlich sinken die Reparaturkosten für Setzungsschäden.This results in numerous advantages. By means of the downwardly tapering outer side surface of the concrete support body there is a significantly improved load transfer from the frame to the surrounding material. In particular, the shaft located under the street tower is thus protected, the life of which is thereby extended. In addition, the repair costs for settlement damage decrease.

Aufgrund der zweiteiligen Ausgestaltung des Rahmens ergeben sich nur geringe Mehrkosten, die deutlich unter den Kosten einer einteiligen Gussausführung liegen. Der Betonstützkörper ist dafür besonders gut geeignet, da er hohe Druckkräfte aufnehmen kann und eine hohe Lebensdauer aufweist. Flüssiger Beton lässt sich mittels einer Form am Gussteil angießen und bildet nach dem Aushärten eine form- und stoffschlüssig Verbindung mit dem Gussteil. Auch eine inverse Herstellung wäre denkbar, bei der ein ausgehärtetes Betonstützteil als Bestandteil einer Gussform für die Gussaufnahme dienen könnte.Due to the two-part design of the frame, there are only small additional costs that are well below the cost of a one-piece cast execution. The concrete support body is particularly well suited for this because it can absorb high pressure forces and has a long service life. Liquid concrete can be cast on the casting by means of a mold and, after hardening, forms a positive and cohesive connection with the casting. An inverse production would be conceivable in which a cured concrete support member could serve as part of a casting mold for the casting.

Durch die Herstellung des Rahmens als Einheit kann dieser in beliebige Öffnungen eingesetzt werden, vorausgesetzt sie bieten diesem ausreichend Platz. Der verbleibende Spalt wird anschließend mit Material wie Asphalt, Schotter oder ähnlichem aufgefüllt. Es ist nicht erforderlich eine konische Fräsung zu erstellen, die neben dem erhöhten Arbeitsaufwand auch die Bauform des Straßenaufsatzes einschränkt. Erfindungsgemäß ist es nunmehr möglich auch nicht runde, vor allem eckige, Rahmen zu verbauen. Somit sinken die Montagekosten und der Einsatzort wird flexibel.By making the frame as a unit this can be used in any openings, provided they provide this sufficient space. The remaining gap is then filled with material such as asphalt, gravel or the like. It is not necessary to create a conical milling, which restricts not only the increased workload but also the design of the road attachment. According to the invention it is now possible not to install round, especially square, frame. This reduces assembly costs and the location becomes flexible.

Dies macht den Einsatz derartiger Straßenaufsätze insbesondere auch am Fahrbahnrand interessant. Gerade aufgrund der hier vorliegenden unterschiedlichen Umgebungsmaterialien und -festigkeiten, kommt die erhöhte Stützung des Rahmens durch den Betonstützkörper voll zum tragen. Durch das Verhindern eines Abkippens des Straßenaufsatzes von der Fahrbahn weg, werden Reparaturen vermieden.This makes the use of such road mats especially at the edge of the road interesting. Precisely because of the different surrounding materials and strengths present here, the increased support of the frame through the concrete support body is fully supported. By preventing the road deck from tipping off the road, repairs are avoided.

Da die Positionierung am Fahrbahnrand erfolgen kann, ist auch eine Gestaltung des Rahmens und des Verschlusselements als Rinnenform besonders interessant, vorzugsweise in Kombination mit einer rechteckigen Form.Since the positioning can be done on the edge of the road, a design of the frame and the closure element as a gutter shape is particularly interesting, preferably in combination with a rectangular shape.

Grundsätzlich besteht zusätzlich die Möglichkeit eine Gussaufnahme und ein Betonstützelement mit unterschiedlicher Grundform zu kombinieren. So könnte beispielsweise eine rechteckige Gussaufnahme für ein rechteckiges Verschlusselement mit einem runden Betonstützelement verbunden sein. Die rechteckige Gussaufnahme könnte so in eine runde Fräsung eingesetzt werden, sofern ein Bauunternehmen vorzugsweise mit einem derartigen Fräser arbeitet.In principle, it is additionally possible to combine a cast receiver and a concrete support element with a different basic shape. For example, a rectangular casting receptacle for a rectangular closure element could be connected to a round concrete support element. The rectangular Gussaufnahme could thus be used in a round milling, if a construction company preferably works with such a router.

Dadurch, dass die Gussaufnahme den Betonstützkörper in Richtung des Verschlusselements überragt, ist es möglich die Fahrbahndecke bis an die Gussaufnahme auszubilden. Dies ist optisch vorteilhaft und der Betonstützkörper wird so nicht nur von unten gestützt, sondern auch von oben umschlossen, sodass einem Kippmoment auf den Straßenaufsatz eine Druckkraft von oben auf den Betonstützkörper entgegenwirkt. Insbesondere am Fahrbahnrand wird hierdurch ein Abkippen von der Fahrbahn weg verhindert.Because the casting receptacle projects beyond the concrete support body in the direction of the closure element, it is possible to form the road surface ceiling as far as the casting receptacle. This is visually advantageous and the concrete support body is thus not only supported from below, but also enclosed from above, so that a tilting moment on the street essay counteracts a compressive force from above the concrete support body. In particular, at the edge of the road thereby tilting away from the roadway is prevented.

Besonders vorteilhaft ist wenigstens ein an der Seite kraft- und/oder formschlüssig angeordnetes Bewehrungselement. Ein solches Bewehrungselement kann die Verbindung zwischen Betonstützkörper und Gussaufnahme deutlich verbessern. Insbesondere kann mittels der Bewehrung der Betonstützkörper von Zugspannungen entlastet werden, die eine ungünstige Belastung für Beton darstellen. Vorzugsweise wird die Bewehrung so ausgelegt, dass der Beton vornehmlich Druckkräfte erfährt und die Bewehrung die Zugkräfte aufnimmt. Die Bewehrung ermöglicht zusätzlich eine verstärkte Verbindung zwischen Gussaufnahme und Betonstützkörper in bestimmten Richtungen. Dies ist insbesondere dann wichtig, wenn der Betonstützkörper die Gussaufnahme nicht vollständig umschließt.Particularly advantageous is at least one on the side force and / or form-fitting arranged reinforcing element. Such a reinforcing element can significantly improve the connection between the concrete support body and the cast seat. In particular, by means of the reinforcement of the concrete support body of tensile stresses can be relieved, which represent an unfavorable burden on concrete. Preferably, the reinforcement is designed so that the concrete undergoes primarily compressive forces and the reinforcement absorbs the tensile forces. The reinforcement additionally enables a reinforced connection between the casting receptacle and the concrete support body in certain directions. This is particularly important if the concrete support body does not completely surround the casting receptacle.

Zusätzlich Vorteile bringt es, wenn die Seite der Gussaufnahme wenigstens eine Vertiefung und/oder wenigstens eine Erhebungen hat. Diese können beispielsweise Stege oder Rillen sein. Hierdurch wird die Verbindung zwischen Betonstützkörper und Gussaufnahme ebenfalls verbessert. Somit bestehen die Möglichkeiten, entweder eine stärkere Verbindung auszubilden oder aber auf eine Bewehrung verzichten zu können, die in der Regel einen zusätzlichen Arbeitsschritt bedeutet, da sie zum Beispiel in an der Gussform angeordnete Laschen eingebracht werden muss.Additional advantages are achieved if the side of the casting receptacle has at least one recess and / or at least one elevation. These may be webs or grooves, for example. As a result, the connection between the concrete support body and casting receptacle is also improved. Thus, there are the possibilities either to form a stronger connection or to be able to dispense with a reinforcement, which is usually an additional step means, for example, it must be introduced in arranged on the mold straps.

Die Erfindung kann weiterhin vorsehen, dass eine Bauhöhe des Betonstützkörpers größer ist als eine Bauhöhe der Gussaufnahme. Dies ermöglicht eine deutliche Vergrößerung der äußeren Seitenfläche und der Lastabtrag in das umgebende Material wird verbessert. Ein so ausgebildeter Betonstützkörper kann dabei auch zur Zentrierung des Rahmens auf dem Schacht genutzt werden.The invention may further provide that a height of the concrete support body is greater than a height of the cast receptacle. This allows a significant increase in the outer side surface and the load transfer into the surrounding material is improved. A trained concrete support body can also be used to center the frame on the shaft.

Von Vorteil ist weiterhin wenn ein Elastomer zwischen dem Straßenaufsatz und dem Schacht angeordnet ist. Die Belastungen auf den Straßenaufsatz werden so vornehmlich über das umgebende Material abgeleitet und der Schacht wird entlastet. Eine deutlich verlängerte Lebensdauer des Schachtes ist die Folge. Zur Vereinfachung der Montage kann das Elastomer schon vor dem Einsetzen an der Unterseite des Straßenaufsatzes befestigt sein. Hierdurch wäre auch bereits beim Transport eine Stoßsicherung gegeben.It is also advantageous if an elastomer is arranged between the street tower and the shaft. The loads on the road top are derived primarily through the surrounding material and the shaft is relieved. A significantly extended life of the shaft is the result. To simplify the assembly, the elastomer may be attached to the underside of the road attachment prior to insertion. As a result, a shock protection would already be given during transport.

Eine besonders vorteilhafte Ausgestaltung der Erfindung sieht vor, dass der Betonstützkörper die Gussaufnahme umfangseitig nicht vollständig umschließt, insbesondere nicht auf einer Gehwegseite. Dies ermöglicht, den Straßenaufsatz in unmittelbarer Nähe zu einem nicht entfernbaren Körper zu positionieren. Der am häufigsten auftretende Fall ist hier eine Bordsteinkante, die deutlich bis unter die Fahrbahnoberfläche reicht. Üblich ist hier eine im Verhältnis zum sichtbaren Überstand 2 bis 7 fache so große Einsetztiefe. Eingesetzt werden kann ein solcher Straßenaufsatz jedoch auch unmittelbar an einer Wand eines Hauses, Tunnels oder ähnlichem.A particularly advantageous embodiment of the invention provides that the concrete support does not completely surround the casting receptacle on the circumference, in particular not on a sidewalk side. This makes it possible to position the street tower in close proximity to a non-removable body. The most common case here is a curb that reaches well below the road surface. The usual is here in relation to the visible supernatant 2 to 7 times as large insertion depth. However, such a street tower can also be used directly on a wall of a house, tunnel or the like.

Weiterhin ist es möglich einen solchen Straßenaufsatz genau andersherum einzusetzen, indem die nicht-umschlossene Seite in Richtung der Fahrbahn angeordnet wird. Bei einer nachträglichen Installation einer Entwässerung am Fahrbahnrand, muss so nicht die Fahrbahndecke beschädigt werden, um den Straßenaufsatz einzusetzen. Aufgrund der großen Stützung des Rahmens über den Betonstützkörper kann ein solcher Straßenaufsatz auch bei weniger stark verdichtetem Bankett hohe Kräfte aufnehmen und die Instandhaltungskosten des Straßenaufsatzes sind gering.Furthermore, it is possible to use such a street tower exactly the other way round by the non-enclosed side is arranged in the direction of the road. In a subsequent installation of drainage at the edge of the road, so does not damage the road surface to use the road essay. Due to the large support of the frame over the concrete support such a road essay can absorb high forces even with less compressed banquet and the maintenance cost of the road essay are low.
