Description

technical area

Technical solution, which concerns a principally new way of installing the upper part of sewer manholes and sewage covers, with the possibility of height and angle adjustment according to the conditions of the terrain at the construction stage, with the possibility of further height adjustment during operation without the Necessity to break the road or other solidified surface, then repair it again without extensive traffic restriction and with minimal expense.

Previous state of the art

• - Der Kanalisationsboden wird auf ein vorher gefertigtes Fundament so aufgesetzt, dass der Schacht vertikal, nicht rechtwinklig zum Terrain oder zu einer behandelten oder verfestigten Oberfläche ist,
• - Auf den Kanalisationsboden werden Kanalisationsschachtringe mit einer einfachen Rille aufgesetzt,
• - Auf die Kanalisationsschachtringe wird ein Kanalisationskonus mit einer einfachen Rille aufgesetzt,
• - Auf den Kanalisationskonus werden Kanalisationsausgleichsringe mit einer einfachen Rille, walz - oder keilförmig aufgesetzt /beziehungsweise wird auch eine Abdeckplatte aufgesetzt/.
• - Auf die Kanalisationsringe wird ein Kanalisationsdeckel, rund oder kantig, aufgesetzt.

After a thorough investigation of the installation of sewer manholes and their lids in the terrain, as well as by studying technical manuals of the manufacturers of lids and manholes in the European Union, the following processes and habits have been identified in their construction and completion.

• - The sewerage floor is placed on a pre-fabricated foundation so that the shaft is vertical, not perpendicular to the terrain or to a treated or solidified surface,
• - Sewer manhole rings are placed on the sewerage floor with a simple groove,
• - On the sewer manhole rings a sewer cone is placed with a simple groove,
• - Sewer equalization rings with a simple groove, wedge - or wedge - shaped are placed on the sewer cone / or a cover plate is also attached.
• - A sewage cover, round or square, is placed on the sewer rings.

All these parts are glued together with cement glue or high-strength foam.

The pits are filled with gravel and the lids are subsequently paved or cast in concrete.

This ideal process is ideal for ideal conditions, which means in practice that it is a new construction, and that on an almost ideally level terrain.

Fundamental assembly problems occur when it comes to sheltered terrain, and therefore, how should you place the lid under a proper pitch because the shaft is vertical and the terrain is sloping. While it is possible to use wedge-shaped rings with a typified tilt that usually does not fit, they are also thin and fragile and break.

A further and significant problem arises during operation, during compaction and when the shaft is pushed into the ground as a result of traffic or when producing a new and higher asphalt carpet.

Then it is necessary to mill off the area of the shaft, to remove the asphalt, to remove the cover, to cut out the ground and to clean everything.

This is followed by an alignment of the height of the lid with the terrain by means of the rings, which, however, ideally never succeed.

Then follows a tried-and-tested process that no manufacturer neither mentions nor recommends openly, and it is an improvisation on the spot.

Specifically, it is about placing wedges under the rings and the lid, inflating a tire tube for closing the inaccuracies from the inside of the shaft and then pouring concrete from the outside.

Then follows a laborious and gradual consolidation of the ballast after strata and paving the environment of the lid.

All of this is indispensable when driving at full speed, which is a huge financial and security problem.

The lids are made in the present from the materials such as cast iron, plastic, composite material, concrete or their mutual combination.

As far as shape is concerned, they are either round or angular, mostly square. As far as the construction is concerned, they are usually made of a frame and a cover plate or a grid. All lids have smooth horizontal joints and mounting surfaces, which is in fact not true, because when the products cool down, during their production, deformations occur and individual parts collide against each other during operation. Some producers solve this problem with an additional seal that accumulates de-icing salt and crushed stone, which causes faster corrosion and wear.

As an absurdity one can state that in the completion work on a complete new pavement with the level of the lid, which in practice looks like they are completely asphalting and rolling the whole road with lids and their surroundings and then milling all sewage covers from the new road, clearing the asphalt, the bottom cut out and clean everything. It follows an adjustment of the height of the lid on the asphalt by means of the rings and also by improvisations, so with underlaying wedges under the rings and the lid, inflating a tire tube for the closure of inaccuracies from the inside of the shaft and subsequent pouring of concrete from the outside All this on a completely new road, then follows a laborious and gradual consolidation of the environment of the cover and the asphalting so that there is no damage and also to create the connection of the newest asphalt with the new asphalt so that it is the responsible do not recognize during the acceptance test.

Core of the technical solution

• a/ Konstruktions - und Montagedetails, die im Stadium des Aufbaus und der Fertigstellung von Kanalisationsschächten wichtig sind, für die Vereinfachung deren Montage auch in anspruchsvollen Böschungsbedingungen,
• b/ Konstruktions - und Montagedetails, die im Prozess der Nutzung wichtig sind, also während deren Betriebs, auch für eine Beschleunigung und Preisminderung deren Reparaturen, weil es aus Sicht des Verkehrs meistens um sehr ausgelastete Konstruktionen und Bauwerke geht.

The purpose of this technical solution is coping with:

• a / Construction and installation details, which are important in the construction and completion stage of sewer manholes, for ease of assembly, even in demanding embankment conditions,
• b / Construction and assembly details that are important in the process of use, ie during their operation, also for acceleration and price reduction of their repairs, because from the point of view of transport it is mostly about very busy constructions and structures.

The key solution in part a /, which deals with this technical solution, is to place the concrete cone and the parts superimposed by means of threaded anchor rods, which serve mainly for the support, placement and anchoring of a cast iron, plastic or composite cover Interaction with rectifying nuts, which serve to align the height and inclination of the lid, with the rectifying nuts from the top and bottom of the lid, allowing it to be fixed, which can be permanent or variable, depending on the shape of the rectifying nuts.

The space between the concrete cone and lid, usually with ring or its parts, is still filled with concrete mix, the threaded anchor rods also form a steel strut of the construction above the cone, which is otherwise not there, making this connection elastic and also solid in vibration, mainly from the wheels of vehicles.

The key solution in part b / with which this technical solution is concerned is that it is not necessary during the operation of a sewer manhole and cover, that is to say when it is deposited as a result of vibrations, a repair of the road or before the laying of a new asphalt carpet. to milled the area of the shaft, to break down the asphalt, to remove the cover, to cut out the bottom and to clean everything, subsequently to align the heights of the cover by means of rings, which ideally never succeed then to improvise with underlay of wedges under the cover and subsequently Pour in concrete from the outside, then compact the area in a labor-intensive way and asphalt it to the desired height.

• Runder Deckel - Kern der technischen Lösung:
  • - Der runde Deckel setzt sich aus einem festen und einem beweglichen Teil oder einer Abdeckplatte zusammen, wobei der bewegliche Teil nach innen eingeschoben oder von außen auf den festen Teil aufgesteckt wird. Der feste Teil hat an seinem Umfang und das von innen oder von außen Wendeln mit Vorsprüngen mindestens in der Zahl von 3 Stück und mehr, wobei der bewegliche Teil ein Gegenstück bildet, es hat an seinem Umfang und zwar vom außen oder vom innen auch Wendeln mit Vorsprüngen in der Zahl und Form spiegelbildlich gegenüber dem festen Teil.
  • - Die Wendeln haben an der Länge Vorsprünge und zwar symmetrische in der Form von V oder asymmetrische in der Form von L, die als selbsthemmend funktionieren, wodurch dem gegenseitigen Spiel zwischen diesen zwei Teilen des Deckels und auch dem Stossen gegeneinander während der Schläge der Räder der Fahrzeuge gehindert wird.
  • - Die Höhe des Deckels wird durch Anheben und Verdrehen des beweglichen Teils so eingestellt, wie es beim Schrauben von Schrauben der Fall ist, aber mit dem Unterschied, dass die Vorsprünge auf der Wendel die Positionsstabilität gegenüber einem spontanen Verdrehen in beliebige Richtung sicherstellen. Um wie viel Vorsprünge der bewegliche Teil verdreht wird, um so viel erhöht oder verringert sich dessen Höhe gegenüber dem festen Teil des Deckels, um h1-hx.
  • - Bei Bedarf eines außerordentlichen Anhebens des Deckels ist es möglich, noch auch ein Zwischenstück einer gleichartigen Konstruktion zu verwenden.
  • - Durch diese technische Lösung werden im Grunde genommen die mit der Wartung und Reparaturen, sonst üblichen zusammenhängenden Arbeiten ausgeschlossen.

The new cover is for putting on the concrete cone in 2 Basic designs and designed as round or square (polygonal). The difference with this new technical solution over various current covers is that:

• Round lid - core of the technical solution:
  • - The round lid is composed of a fixed and a movable part or a cover plate, wherein the movable part is inserted inwardly or attached to the outside of the fixed part. The fixed part has on its circumference and that of inside or outside spirals with projections at least in the number of 3 pieces and more, wherein the movable part forms a counterpart, it has on its periphery and from the outside or inside also coiled with Projections in number and shape mirror image of the solid part.
  • - The coils have projections on the length, namely symmetrical in the form of V or asymmetrical in the form of L, which function as self-locking, whereby the mutual play between these two parts of the lid and also against each other during the beating of the wheels Vehicles is prevented.
  • - The height of the lid is adjusted by lifting and twisting the movable part, as it is the case with screws screws, but with the difference that the projections on the coil ensure the position stability against spontaneous rotation in any direction. By how many protrusions the movable part is twisted, the height of which increases or decreases with respect to the fixed part of the cover by h1-hx.
  • - If an extraordinary lifting of the lid is required, it is possible to use an intermediate piece of a similar construction.
  • - By this technical solution are basically excluded with the maintenance and repairs, otherwise related work.

• - Der quadratische (mehreckige) Deckel) - setzt sich aus einem festen und einem beweglichen Teil oder auch aus einer Abdeckplatte zusammen, wobei der bewegliche Teil nach innen eingeschoben oder von außen auf den festen Teil aufgesteckt wird. Der feste Teil hat an seinem Umfang und es von innen oder von außen treppenförmige Vorsprünge, der bewegliche Teil bildet ein Gegenstück, er hat an seinem Umfang und es von außen oder von innen auch treppenförmige Vorsprünge in der Zahl nach dem festen Teil.
• - Die treppenförmigen Vorsprünge sind so entworfen, dass den beweglichen Teil auf dem quadratischen Deckel bis zu 4-mal je 90° anzuheben und zu verdrehen möglich ist, was bedeutet, dass es 4 Höhenpositionen auszurichten möglich sind, also um 1 Höhe je jede Verdrehung um 90°, beim mehreckigen Deckel ist die Anzahl der Höhenpositionen nach der Anzahl der Seiten des Vielecks.
• - Bei Bedarf eines außerordentlichen Anhebens des Deckels ist es möglich, noch auch ein Zwischenstück einer gleichartigen Konstruktion zu verwenden.
• - Durch diese technische Lösung werden im Grunde genommen die mit der Wartung und Reparaturen, sonst üblichen zusammenhängenden Arbeiten ausgeschlossen.

Square (polygonal) lid - the core of the technical solution:

• - The square (polygonal) cover) - is composed of a fixed and a movable part or a cover plate together, wherein the movable part is inserted inwardly or plugged from the outside onto the fixed part. The fixed part has on its circumference and it from inside or outside stepped projections, the movable part forms a counterpart, it has on its periphery and it from outside or from inside also stair-shaped projections in the number after the fixed part.
• - The stair-shaped projections are designed so that the movable part on the square lid is possible to raise and twist up to 4 times at 90 ° each, which means that it is possible to align 4 vertical positions, ie by 1 height per each rotation 90 °, with the polygonal lid, the number of height positions depends on the number of sides of the polygon.
• - If necessary, an extraordinary lifting of the lid, it is possible to use even an intermediate piece of a similar construction.
• - By this technical solution are basically excluded with the maintenance and repairs, otherwise related work.
