Description

Underground space in city with narrow streets

In many densely populated cities with narrow streets, such as Amsterdam, car traffic has become an increasing problem 5. Such cities are often not arranged or designed to give the cars ample access to the center, while in many cases it is impossible to make entrances and exits for underground parking space. The streets are marred by large quantities of 10 cars parked, which space is withdrawn from walking and sitting areas for the public. The lack of (parking) space limits the business use of the buildings, as well as the private use of homes and apartments, as there is not enough access space for their residents for their cars.

In the past, proposals have already been made to use the underground space for parking purposes. However, the costs for making entrances and exits are prohibitive, as a result of which such plans have remained on the drawing board 20.

The present invention provides a method for providing underground parking spaces and / or a roadway and / or a concrete floor for this and / or other purposes in slack or marshy soil, wherein surface water is pumped away if necessary, deep walls in the marshy soil up to a sand layer, a concrete top wall is placed between the deep walls, and then the soggy bottom under the upper concrete plate is removed, for example, being excavated and / or pumped away, whereby the underground parking places and / or the roadway and / or the concrete floor is installed in an existing canal after it has been filled in with sand.

Calculations have shown that by installing one or more concrete floors in the marshy soil, for example under a canal, the costs per parking space, and for other surfaces, are roughly limited to the current costs for constructing parking spaces. This is partly due to the system that the tours are already laid at the beginning of the center of the city, creating an underground network of parking spaces and spaces.

The number of concrete floors is preferably two, more preferably more than four and even more preferably six, so that the costs are further limited. In addition, the various utility facilities, such as gas, water, light, (fiber optic) cables for telecommunications and the like can then be laid in the lower space.

The underground spaces are preferably divided into vertically separable compartments which in fire situations can be closed by means of fire doors so that the risk thereof is limited to such a compartment.

In a further preferred embodiment, use is made of geothermal heat for heating and / or cooling the air streams in at least the upper spaces in order to allow climate control to take place without using fossil fuels.

In a further preferred embodiment, after the installation of at least two floors, water is left in the canal and work for the installation of deeper layers is continued below, that is to say in the space between the floors already applied. The further course of the work is thus hidden from the view of the residents, so that nuisance for the environment is kept to a minimum.

Further advantages, features and details of the present invention will be elucidated on the basis of the following description of the preferred embodiment thereof, with reference to the accompanying drawing, in which:

Figure 1 is a partial schematic view of an underground space according to the present invention;

Figure 2-6 consecutive method steps for realizing the space shown in Figure 1; and Figure 7 shows a cross-sectional view of a climate control system for the preferred embodiment as shown in Figure 1.

Underneath a moat C, on which banks on either side parking places O are situated, below the bottom 10 of the moat C a number of floors 11, 12, 13, 14, 15, 16 are provided with a span of 28 to 30 meters between so-called deep walls 20, 21 that are watertight and that can extend downwards to a depth of 60 meters in the bottom, preferably up to a layer of sand 20 below the limp, clay-like bottom.

In a manner not shown, the underground spaces between the bottom 10 of the canal C and at least a number of the spaces between the floors can be vertically separated with lockable fire doors.

25 In a city such as Amsterdam, a network of such floors can be installed under the canals, so that access can be achieved from, for example, the subsurface of the Amstel to most locations in Amsterdam, as well as from Weesperzijde, Hobbemakade, Sloterkade 30 and the Haarlemmerweg. Therefore, there is no need to make supply and discharge roads near the canals in the old city center.

The vehicles can be provided with vehicle identification, so that only certain identified vehicles have access to the underground space. The facades of the canals can be projected onto the side walls of the room, so that the resident or business user can easily see where he is and where he can park his automobile. Sufficient space can be created for underground shops, squash halls, fitness rooms and the like in order to optimally use the limited space in a densely populated city such as Amsterdam.

In the method according to the present invention, first a houseboat W is removed, after which a canal C with sand is filled in. After removing waste, such as an old bicycle B, the deep walls 20, 21 are dug to the said depth or less into the ground or otherwise installed therein (Figure 3). A concrete bottom 10 is then provided between said deep walls 20, 21. Between sheet pile walls 42, 43, an excavator E can then dig the peat-20 or clay-like bottom layer S to the desired depth. The material from bottom layer S can preferably be discharged per pipeline, preferably per a pipeline floating in the canals. In some cases, digging may hardly be necessary if sufficient water is added.

It will be clear that the water in the moat C above the concrete floor 41 remains much cleaner than in the current circumstances, since the moat C is provided with a concrete bottom, so that no contamination from the bottom can contaminate the water.

After a further concrete floor 11 has been applied, a further underlayer can be dug away with the excavator E (Figure 5), whereafter a further underfloor 12 can be provided underneath. It will be clear that after the installation of the first concrete floor 10, all work can be carried out without the city and its city dwellers being inconvenienced by this.

As shown in Figure 7, excess heat H can be pumped down into soil shafts 71, 72 in the summer, while, for example, heated air 10 can be heated via heat exchangers 72, 73 and a heat pump 74 through heat exchangers 75, 76 into at least the bottom compartments. be pumped.

For example, at a depth of 60 m, the geothermal heat is fairly constant, and in the order of magnitude of 10 ° C-12 ° C. In the summer, at an outside temperature of, for example, 25 ° C, the earth temperature of 10 ° C-12 ° C can be used for cooling. On the other hand, in winter, when the outside temperature can drop to -10 ° C, the earth temperature of 10 ° C-12 ° C can be used for heating.

Storage of cold and / or heat reduces the need for alternative energy sources for cooling and / or heating the spaces installed underground. If desired, additional installations can be provided for cooling and / or reheating the underground spaces to a desired temperature.

The present invention is not limited to the preferred embodiment described above. The rights described are defined by the following claims in the scope of which many modifications are conceivable.
