Abstract

The invention relates to a shaft building comprising a monolithically-shaped shaft lower part, whereupon one or more shaft pipes and/or shaft rings and a cone can be placed depending on the embodiment involved. Channels for different media lines designed for liquid and gas-phase media, for energy or for information are preferably located on the outer wall or in the wall of the shaft ring or shaft pipe or in the shaft lower part. One shaft ring or pipe can have one or more channels for media lines. Said channels pertaining to the individual media lines are preferably aligned above each other. The decisive advantage of the innovative shaft building is that different media are integrated into lines in a single shaft building. Costs associated with inspection and maintenance are significantly reduced. When new lines are constructed or lines are serviced, costs associated with the construction of other shaft buildings are saved.

Description

Multimedia shaft structure

The invention relates to a shaft structure for the open or closed passage of liquid media by means of free-flowing lines or pressure lines, such as drinking water, rainwater, fire-fighting water, dirty water, mixed water, heating water, steam, gaseous media in the liquid phase, gaseous media such as town gas or natural gas, and energy - And / or information transmission lines and / or for the passage of transport goods in goods transport channels. Collecting channels for city supply lines are known from the Fritzsche, J .: Technical Building Equipment, Verlag für Bauwesen, Berlin 1966, p. 58. Such collecting channels enable the open implementation of a wide variety of media lines, such as dirty water line, rain water line, drinking water line, heating line, electrical line, telecommunications lines and gas lines. Due to the open laying of the media lines on the channel floor or on trusses, which are arranged on the shaft walls, there are regular line faults in the accessible collecting channels due to the biting of predators or rodents or through vandalism.

Another significant disadvantage of the collecting channels is that no emergency emptying of individual media lines, e.g. B. the waste water line, can be made in the event of an overflow because this would flood all other media lines.

Another disadvantage of the known collecting channels is that the development and construction costs, in particular due to the large trench width, are disproportionately high in comparison to conventional forms (buried media lines in trenches). As a result, the use of collecting channels was and is restricted to urban areas.

In addition, a hood-shaped shaft structure is known from the font "MONO development, revision + distribution shaft", publisher: Hans Wörmseher, Hochstrasse 20, D-94099 Ruhrsdorf, edition of 01.02.1999), which allows the passage and integration of different media lines for dirty water, Water, natural gas and Telecommunications enables. The shaft structure, which is open at the bottom, is built on strip foundations. These do not offer sufficient stability, particularly in the case of uneven load absorption and the signs of settlement between the shaft structure and the in-line or out-of-ground, underground media lines.

Another decisive disadvantage is that the shaft structure, which is open at the bottom, has no retention space, so that in the event of an accident or blockage (backflow), the media lines concerned cannot be emptied into the interior of the shaft structure.

The proposed shaft structure also provides for the water and waste water pipes to be routed on the shaft floor. This does not guarantee the occupational safety of people during maintenance or inspection work inside the shaft structure.

Another disadvantage is that the electrical cables are dragged outside the shaft structure.

Another disadvantage is the comparatively high space requirement of the rectangular shaft structure. Another disadvantage of the proposed solution is that the subsequent incorporation of media lines makes it necessary to drill into the shaft structure and insert seals. Another disadvantage of the known solutions of the prior art is that inspection work on the media lines carried out make it necessary to open the manhole cover and to inspect the manhole structure.

The object of the invention is to eliminate the disadvantages of the prior art and to propose a shaft structure that enables the secure integration of a wide variety of media lines, without thereby restricting the accessibility of the shaft structure. In addition, the shaft structure should have a virtually tension-free integration of the inlets and outlets of the media to be passed through and a safe absorption of all occurring load situations (e.g. dynamic stress by means of pressure waves within the passages) and can be produced with little manufacturing or assembly effort. The shaft structure should also enable the simple integration of new media lines. In addition, any emergency situations in the shaft structure and / or on the media lines should be recognized more quickly.

According to the invention the object is solved by the features of the main claim. Further developments are preferably the subject of the dependent claims.

The manhole structure consists of a monolithically shaped manhole base on which, depending on the application, one or more manhole pipes and / or manhole rings and a cone can be placed. The media lines for drinking water, extinguishing water, dirty or mixed water, rain water, heating water, steam, gas, etc. are carried out in separate pipes or open channels. The power supply and telecommunications lines are carried out outside the shaft structure in protective pipes (armored pipes). Within the shaft structure, the protective tubes designed as lead-through segments optionally have lockable inspection openings.

The passages of the media lines are preferably arranged on the outer wall or in the wall of the shaft ring or shaft pipe or in the lower part of the shaft. Depending on the local conditions (inclination of the inflows and outflows of the individual media lines, number of media feed-throughs to be integrated, etc.), one or more manhole rings or manhole pipes are placed on the manhole base. A shaft ring or pipe can have one or more bushings for media lines.

The feedthroughs of the individual media lines are preferably arranged one above the other in order not to impair the accessibility of the shaft if the nominal width of the shaft structure is as small as possible for cost reasons. The inflows and outflows of liquid media are advantageously integrated flush and double articulated in the area of the wall openings of the manhole rings or manhole pipes. By the articulated, sleeve-like integration of the inlets and outlets in the area of the wall allows shear stresses due to settling movements of the shaft structure to be elastically absorbed in relation to the buried media lines and safely transmitted to the wall of the shaft structure. The protective pipes (armored pipes) as a sheathing for electrical power and telecommunication lines and the redundantly installed empty pipes for the subsequent integration or looping through of additional media lines are also articulated in the wall of the shaft structure.

The articulated connection is made in water and sewage pipes by means of sleeves and joint pieces, which are arranged in the wall of the shaft structure part for the purpose of favorable force introduction. This enables the pipelines to compensate for changes in location within defined tolerances during settlement movements without causing leaks.

To prevent other media lines (gas, electrical) from shearing, media-specific connections of these lines are provided. In the simplest case, empty pipes or sleeves are articulated into the wall of the shaft structure using sleeves. Movements within wide tolerances can be compensated for by a sufficiently large play between the inner wall of the sleeve or the empty pipe and the outer wall of the media line. The penetration of groundwater or ore is prevented with the help of known sealing sleeves.

The passage of the media lines through the shaft structure can be straight as well as curved. The open waste water pipe, which is preferably arranged in the lower part of the shaft, can be carried out either in the center or off-center. To ensure occupational safety, a walk-through grating is arranged on the shaft base when the free-sighting line is carried out in the center, which is designed to be removable, foldable or pivotable, if necessary.

In order to ensure the accessibility required for maintenance personnel (clear width in all levels of the shaft structure of at least 1000 mm), the shaft ducts are preferably installed in the wall of the shaft ring or shaft pipe arranged. In an alternative embodiment, the passages are located tangentially on the outer wall of the shaft ring or pipe. The complete integration of all media feedthroughs in the reinforced wall of the shaft structure, in particular the shaft pipes or shaft rings, has proven to be particularly advantageous (external molding). The feedthrough segments of the individual media are preferably arranged vertically aligned one above the other. In a preferred embodiment, the lead-through segments have gas-tight and / or watertight, closable inspection openings. As a result, the power supply and telecommunications lines in particular are protected from damage caused by rodents being bitten.

Alternatively, there is the option of passing the media lines through channels, openings or pipes inside the wall of the shaft structure without an inspection opening. In the interior of the shaft structure, the tapered wall has predetermined breaking points at the relevant points at which the media lines are carried out, which can be opened and closed again if necessary using simple means. This ensures that these media lines are protected against vandalism.

The shaft structure preferably has sensors in the interior, in the feed-through segments and / or in the integrated empty pipes (armored pipes) which record the system status of the respective media or media feedthroughs. The temperature, pressure, gas concentration, etc. or a combination of several physical variables are preferably detected via the sensors. The measurement values can be saved and evaluated on site using single-chip microcomputers. In this case, the measured values are visualized by simple LED displays.

In a preferred development, the measured data determined are forwarded to a monitoring device and, if necessary, processed and stored. The measurement data is preferably forwarded wirelessly using existing mobile radio networks. The data is transferred continuously or periodically. The measurement of relevant measured variables (temperature) can be carried out cyclically using a microcomputer integrated in the shaft structure. If a significant change in the measured values is logged within predefinable time intervals, the microcomputer records the respective measured variable in time intervals that become smaller. If a critical setpoint is exceeded or undershot, a warning message is sent to the network operator. In an alternative, likewise preferred embodiment, the measurement variables are forwarded via the telecommunication lines running through the shaft structure.

The decisive advantage of the innovative shaft structure is that different media lines are brought together in a single shaft structure. This significantly minimizes the costs for inspection and repair work. Likewise, costs for the construction of further shaft structures are saved in the construction of new or renovation of routes, in which the different media have so far been routed separately from one another.The space-saving arrangement of the passage segments inside the shaft structure means that a large number of passages can be integrated compared to known systems become. This opens up the possibility of preventively integrating and executing media lines that were not in use at the time the shaft structure was commissioned. At a later point in time, simple technological means can be used to integrate additional media lines through the protective pipes (armored pipes) connecting the manhole structures. This enables, for example, the subsequent supply of a catchment area with fiber optic cable technology as an information transmission medium. Redundant pipelines for water or mixed water, in particular rainwater and other liquid or gaseous media, can also be kept dry and redundant. This gives you the opportunity to compensate for the increased need for supply and disposal services when you subsequently build on an area or relocate other businesses. At the same time, this creates the possibility of introducing the respective media into a redundant media line in the event of an accident (e.g. congestion or blockages within pipelines). This means that repair work can immediately be carried out on the damaged line without the supply or disposal being interrupted by the consumer.

So far, it was considered a disadvantage that media lines could not be looped through the shaft structure, but had to be laid outside. In contrast, further studies have shown that there are applications in which laying media lines outside in the immediate vicinity of the shaft structure has significant advantages. So far, media lines have been routed past existing shaft structures. In the case of necessary inspection or repair work, a large-volume excavation had to be carried out due to the inaccurate position of these lines. To protect the media lines from possible damage during excavation, the ground must be removed due to the imprecise position of the media lines in manual excavation or using suction technology.

In order to counter the risk of damage as far as possible, in many cases several media lines that had to be led around a shaft structure were laid horizontally spaced side by side. This, however, creates the latent risk of mutual interference from fields or leakage currents. In addition, large areas of the route (roads, footpaths) must be closed during maintenance work.

In contrast, the innovative manhole structure with an external molding offers the possibility of arranging several media lines to be passed vertically one above the other (in alignment or offset) above the projecting area of the molding. Due to the known external dimensions of the shaft structure, which can advantageously be called up on machine-readable data carriers on or in the shaft structure, the exact position of the media lines can be determined during repair work. This also makes the necessary effort for excavation significant minimized and the risk of mechanical damage during shaft work largely minimized.

Another advantage of the manhole structure is the reduction in manufacturing costs through standardization in the manufacture of large-volume manhole rings, manhole pipes and manhole bases. In the same way, the feedthrough segments can be manufactured according to the modular principle in large batch sizes that are favorable in terms of production technology, or can be individually manufactured as a special component depending on geographic conditions. By using preferred external dimensions, standardization and thus a high degree of prefabrication can also be achieved with special components.

The parameters stored on a memory, in particular the position of the shaft structure, can be forwarded wirelessly to a miniaturized transmitter-receiver unit on the shaft structure or outside of it. This makes it easy to find a damaged shaft structure using radio regulations (e.g. using known GPS location systems). Especially in densely populated metropolitan areas, in which a large number of shaft structures, especially in intersection areas, are arranged in close proximity to one another, this gives the option in emergencies (wastewater congestion, pipeline rupture, access to fire-fighting water pipes in the event of fire, leaks of dangerous liquids, etc.) Detect pipeline in the respective shaft structure in the shortest possible time.

By using diagnostic tools, important system data about the respective condition of the media line concerned (temperature, pressure, surface tensions, conductivity, gas concentration, specific noises, etc.) can also be obtained. recorded, saved and evaluated. In connection with so-called "data cell phones", measured values and characteristic data of a shaft structure can be called up.

In a cost-effective alternative, barcode identifiers are arranged in the visible area of the shaft structure, which enable the information stored on it to be read enable nen about the location and the specific design of the respective shaft structure with the help of a known barcode reader.

The innovative manhole structure also has another significant advantage: So far, in the known state-of-the-art solutions in the manhole base in the so-called TWIN manhole system, two lines were laid next to each other at the same level or with small bed differences of up to 60 (70) cm. This consequently leads to wider trenches and larger shafts than if the two sewage pipes were laid on top of one another (rainwater and dirty water). Known multi-part manhole structures, which consist of manhole bottom part, manhole pipe or ring and cone, have the disadvantage that when two pipes are laid one above the other in manhole elements arranged one above the other, each pipe must have a concrete cover of at least 25 cm above and below for reasons of strength , Therefore, known multi-part manhole structures can only be used depending on the nominal diameter of the lower pipeline from a certain minimum base difference.

This gap in use can also be closed by the innovative shaft structure. By integrating two superimposed bushings or feed-through segments (6) z. B. for rain and dirty water in a manhole structure element (e.g. in the manhole base or in the manhole pipe), the innovative manhole structure can be used successfully even with small base differences due to the reduction of the concrete cover

Known multi-part shaft structures also have the disadvantage that, due to the constructive solution, short-term impulse-like peak loads caused by gushing and reflection waves lead to tensile and torsional loads on the closed rainwater flow section. These loads are harmful to concrete shafts. The external shaping of the innovative shaft structure solves this problem, so that only pressure loads occur in chess that the concrete can absorb ideally and permanently.

The technological problem of cooling the power supply lines to be implemented is solved by the lines outside the shaft structures preferably be buried underground. This enables heat to be transferred to the normally moist soil without any problems. Alternatively, it can also be laid by embedding it in other thermally conductive materials (floor mortar, concrete). Within the lead-through segments inside the shaft structure and within the pipes used for the line laying between the individual shaft structures, the heat generated is preferably dissipated by means of forced ventilation. For this purpose, the lead-through segment or the water and gas tight lockable inspection opening is connected via an air duct to a high point of the shaft structure, preferably in the upper area of the cone. Due to the existing temperature differences and the existing air flows in the shaft structure, the heat of the electrical lines is automatically dissipated. In order to prevent rainwater from penetrating through any openings in the manhole cover, the outlet opening of the air duct is cranked or provided with a movable ventilation flap.

The invention is described below using several exemplary embodiments and illustrated in more detail in drawings.

FIG. 9: a shaft structure with a goods transport channel to be inspected over the lower part of the shaft structure and below the previous lower part of the shaft structure. Figure 1 shows a shaft structure consisting of a lower part of the shaft structure, in the bottom of which an open waste water pipe is carried out off-center. The partially reinforced wall of the lower part of the shaft structure has two passage segments 6f, 6g, which are arranged in alignment one above the other, for the passage of a drinking water and an extinguishing water pipe through the interior of the shaft wall. A shaft pipe 2 with a passage segment 6k arranged in the reinforced shaft wall 14 for the passage of rainwater sits positively on the shaft structure lower part 1. The lead-through segment 6k has an overhead inspection and inspection opening 19 provided with a liquid-tight closure (not shown). A further shaft pipe 2 is placed on this shaft pipe 2, in the reinforced wall 14 of which a further passage segment 6k with an inspection opening 19 located at the top is arranged. The pass-through segment 6k serves to receive only slightly polluted rainwater. A compact shaft ring 3 is seated on this shaft pipe 2, with a passage segment 6e integrated in the reinforced wall 14 of the shaft structure part, which serves for the passage of natural gas. The reinforced walls of the shaft pipes 2 and the shaft ring 3 are formed in this exemplary embodiment as a cuboidal outer molding. The shaft pipes 2 and the shaft ring 3 are each monolithically shaped shaft building elements made of concrete, polymer concrete or plastic, which are produced by master forms. A well-known cone 4 with a manhole cover attached to it forms the end of the manhole structure.

The advantage of this design is that the shaft structure can be freely and freely accessed for cleaning, inspection and repair work. The inspection openings 19 arranged laterally in the inner wall of the shaft pipe 2 enable easy access with cleaning tools. It is also easy to lower an inspection camera through the inspection openings facing upwards.

FIG. 2 shows another shaft structure with a monolithic shaft structure lower part 1, in the berm 7 of which an open waste water line 11 is off-center is carried out. A passage segment 6k for the passage of rainwater is integrated in the reinforced wall 14 of the lower shaft part 1 (external molding). Through an obliquely upward channel 26, which is closed by a waterproof inspection cover, easy inspection and cleaning of the rainwater passage segment 6k is possible. A passage segment 6h for the passage of a dirty water pressure line is arranged below the passage segment 6k for the rainwater.

A shaft pipe 2 with two passage segments 6f, 6e running in the reinforced wall 14 of the shaft pipe 2 sits positively on the lower part 1 of the shaft structure for the passage of drinking water or gas. For reasons of cost, no inspection openings are provided on the shaft pipe 2. In the event of necessary repair work, access to the through-passage segments 6e, 6f can be provided via predetermined breaking points in the wall of the shaft pipe 2, which are not shown in detail. The missing inspection openings offer secure protection against vandalism. In particular, this prevents manipulation or willful destruction of the media lines.

On the shaft pipe 2 there is a shaft ring 3 with several passage segments 6a, 6b, 6c, 6d integrated in the reinforced wall for the implementation of various media lines (TV, radio, pay TV, electrical energy). Through a large inspection opening 19, which is provided with a liquid-tight seal, maintenance and repair work can be carried out easily and in an ergonomically favorable position on the media lines running in the upper part of the shaft structure or the associated communication or energy supply devices.

In order to prevent heat accumulation within the cavity, which is formed by the leadthroughs of the electrical lines, the inspection room has a ventilation duct 5 which runs upwards and leads to the upper edge of the ground. To protect against vandalism, ventilation duct 5 opens inside the shaft structure in the area of the shaft cover. FIG. 3 shows a shaft structure with a compact lower part 1 of the shaft structure, in the berm 7 of which an open waste water line 11 is carried out off-center. In the reinforced wall 14 of the lower shaft part 1, a straight passage segment 6h of a dirty water pressure line is arranged. A monolithically shaped shaft pipe 2 rests on the shaft structure lower part 1, in the reinforced wall 14 of which a rainwater pipe with a diameter of 800 mm is passed. For cleaning and inspection purposes, the passage segment 6k is connected to the interior of the shaft structure via an obliquely upward channel. A vertically arranged, watertight and closable inspection opening 19 enables the channel to be opened easily. A shaft ring 3 is arranged on the shaft pipe 2 and, like in FIG. 2, has a plurality of transmission segments arranged one above the other for the transmission of media and energy supply lines. Waste heat from the electrical lines is forcibly discharged via a ventilation duct 5 located at the top and running through the adjacent cone. In addition to the passage segments 6 for media and Elt lines, the shaft ring 3 has two further passage segments 6 arranged offset from one another for the passage of liquid or gaseous media.

FIG. 4 shows a manhole structure with a monolithic manhole lower part 1, which in the reinforced wall 14 has an arcuate shape in plan view

Pass-through segment 6k for the passage of rainwater. In the

Passage segment 6k opens another inlet 17.

Due to the bevel 16 of the lower area of the substantially cuboid

Formation 44 of the reinforced wall 14 of the lower shaft part 1 is a lighter

Filling with soil possible.

The monolithic shaft lower part 1 also has further passage segments 6 for the passage of further media through the shaft structure.

Access to individual transit segments is secured via defined breaking points, which in the event of an accident provide quick access to the relevant ones

Enable media lines. To protect against vandalism, a label is The predetermined breaking points are dispensed with, since the position of the power supply line can be easily determined using known technical means.

The shaft structure is used in particular when there are small bed differences between the sewage pipe running in the berm and the rainwater pipe above it. Depending on the geographic location and the gradient to be realized, the shaft structure can be equipped with additional shaft pipes or shaft rings that are standardized in their dimensions or manufactured as special components

be completed. With this shaft structure can also - in contrast to known solutions such. B. the TWTN shaft - a cheaper trench geometry can be realized.

FIG. 5 shows a sectional side view of another shaft structure, in which the rainwater passage segment 6k arranged in the shaft ring 2 is arranged in alignment above the wall of the lower shaft part 1. This arrangement of the passage segment 6k has the advantage that pulse-like loads directed horizontally in the direction of the shaft interior (in particular as a result of heavy rain-induced surge and / or reflection waves) only generate pressure loads within the shaft structure that are safely and permanently absorbed by the concrete used.

On the lower shaft part 1, which has an open, eccentrically arranged dirty water channel 11 in the berm 7, there is a compensating ring 15 for individual adaptation to the bottom difference to be realized between the dirty water pipe 11 and the rainwater pipe running in the reinforced wall 14 of the shaft pipe 2 arranged. A shaft ring 3 which is connected to the shaft pipe 2 in a form-fitting, push-fit or non-positive manner and a cone 4 resting thereon form the upper end of the shaft structure.

As a result of the external shaping of the passage segment 6k in the shaft pipe 2, as in the exemplary embodiment according to FIG. 4, the static and dynamic stresses occurring and acting in the direction of the shaft interior can be reliably captured and transferred to the concrete shaft as pure compressive stresses that the construction material concrete can absorb safely and permanently. Another advantage of the parallelepiped-shaped external shaping in the area of the reinforced wall 14 of the shaft pipe 2 is that media lines 27 (e.g. for gas, electrical energy and drinking water) laid in the ground above the protruding projection 44 can be detected more easily in the event of accidents can, since their location is exactly defined by the dimensions of the shaft structure and the molding 44. Particularly in cases of use in which different media lines coming from different directions are brought together on or in the shaft structure, this arrangement enables the media lines in question to be found and exposed quickly in the event of necessary repair work.

FIG. 6 shows a further shaft structure with a shaft pipe 2 placed on the lower shaft part 1. A passage segment 6k for the passage of rain water is arranged in the reinforced wall 14 of the shaft pipe 2. The curve-shaped course of the passage segment 6k in the top view causes a change in direction of the medium flowing through.

As a result of this change in direction, heavy impulse-like load peaks occur in the event of heavy rain and the resulting surge and reflection waves, which generate corresponding resulting forces in the shaft structure. In known solutions of the prior art, in which the rainwater pipe is guided through the interior of the shaft structure as a push-through pipe or in a console, such loads always lead to tensile stresses or torsional moments. In contrast, the innovative shaft structure enables the forces generated to be converted into pure compressive stresses by the external shaping of the rainwater feedthrough. These are ideally absorbed by the concrete and therefore do not lead to cracks or premature fatigue of the construction material. The passage segment 6k has a further inlet 17 for the integration of a closed rainwater pipe, not shown in detail. The lead-through segment 6k has an upward opening 28 at its top, to which a revision pipe 29 is connected via a socket with a sleeve, which leads to the upper edge of the road cover. This creates the prerequisite for the first time to carry out an inspection of the rainwater pipe without climbing the shaft structure, in particular in the area of the additionally integrated inlet 17. It is thus possible to use known endoscopes to carry out an analysis of the degree of soiling or of the state of wear of the area of the passage segment 6k which is the most exposed to the flow, without having to walk inside the shaft.

In addition, the passage segment 6k has a connecting channel 30 which opens into the interior of the shaft structure. The vertical inspection opening 19 can be closed in a pressure-tight manner by known means and permits rapid opening during cleaning or repair work.

FIG. 7 shows a manhole structure in which the monolithic manhole pipe 2 in the region of the reinforced wall 14 has a passage segment 6k provided with a change in direction with a further inlet 17. The passage segment 6k is used for the closed passage of rainwater. In the upper area of the lead-through segment 6k, an endoscopy channel 22 runs inside the wall of the shaft pipe 2 and the cone 4 placed thereon. With known endoscopes, the channel enables the closed rainwater pipe to be inspected from the street level without having to enter the interior of the shaft structure, including the Opening the inspection cover 19 of the passage segment 6k is necessary. The opening of the endoscopy channel 22 located at street level is secured by a closure which can be driven over by a vehicle. Depending on the application, this closure can be designed to be pressure-tight or have ventilation openings.

Figure 8 shows a shaft structure in which the shaft pipe 2 is connected to an adjacent goods transport channel 23 through an inspection opening. The goods transport channel is used to use an underground transport system to transport goods, especially within urban areas. This can in particular General cargo from shipping warehouses can be transported directly to customers or end consumers. The inspection opening 19 and the access 25 to the goods transport channel 23 are dimensioned such that maintenance or repair work can be carried out in the goods transport channel 23 via the shaft structure.

FIG. 9 shows a further shaft structure in which a goods transport channel 23 is arranged below the base of the dirty water line 11 on the lower part 1 of the shaft. A pressure-tight lockable access 25 enables inspection work in the lower-lying goods transport channel 23.
