Description
Concrete slabThe present invention relates to a mobile reinforced slab and the use thereof. Theinvention also relates to a mobile vehicle wash arrangement, and a method of installing such arrangement.
Backqround of the invention Constructions, typically buildings of varying sizes, may be founded on a reinforcedconcrete slab. Such foundations are typically produced by on-site casting. Once theconcrete composition has set, the formed concrete slab is immovable and cannot beremoved and transported away to another site. lt may be desirable to enable movementnot only of a building or house but also of an entire foundation thereby restoring theground for other purposes. Should the foundation be movable, it could be reused asfoundation on another site while saving costs and leaving the previously used groundintact.
Transporting a removably arranged concrete slab as foundation and a building per semounted on such foundation would thus be an alternative to permanent foundations andbuildings.
A further advantage of such foundation would be that prefabricated slabs could beproduced in a more cost-effective way while providing a higher quality since greatervolumes could be continuously produced while benefiting from controlled processconditions such as substantially constant humidity and temperature ranges. An objectiveof the present invention is thus to provide such concrete slab for use as foundation forbuildings.
Car washes are generally known as permanent indoor installations extensively availableat facilities such as petrol stations. Outdoor car washes are also available even thoughnot as abundant. A problem with outdoor car washes is the use thereof at a temperaturebelow the freezing point. ln particular, it must be safeguarded drained water does notfreeze which would lead to slippery surfaces and danger for people washing their cars aswell as detrimental effects on equipment such as hoses, pumps and other machinerywhich may be damaged if remaining water freezes. One solution to this would be heatingthe car wash but this would, if not performed in an optimal way result in both expensiveheating as well as complex arrangement for providing such heating. For example, if theheating would be provided below the ground, such an installation would both beexpensive and in case the heating device breaks down or heating ducts start to leak andreplacement is needed, such operation would require removal of the device below theground and replacement of e.g. heating device, heating ducts or similar equipment. A further inconvenience with present car wash installations, even outdoor washes, is that they are not movable. Needless to say, it often happens areas of installations such as carwashes are closed down to whereby such unmovable installations must be demounted requiring considerable efforts to restore and decontaminate the ground.
The present invention therefore intends to provide a solution to this problem by providinga mobile car wash arrangement for use in unheated environments coping with theproblems referred to herein. Moreover, the present invention intends to provide a solutionwhereby a mobile arrangement for vehicle washing can be combined with additionalmovable vehicle-related services such as tire change, car workshops or other useful carservices. Mobile arrangements offering several services would additionally save bothspace, resources, and time for both employees at service sites and vehicle ownersrequiring such services. Moreover, conventional car washes of today usually require awell to treat drained water. Such wells often suffer from fouling due to sludge or solidparticles entrained in the drained water flow block the passage to the well whicheventually may have to be flushed by highly pressurized water. Also, this kind of watertreatment is many times not efficient to eliminate toxic or environmentally harmfulsubstances which thus are conveyed to municipal water treatment plants which are notdesigned to handle such substances. Harmful effluents from car washes may thus beemitted to water systems thereby causing pollution. The present invention intends to solve the above problems.
The invention The present invention relates to a reinforced concrete slab comprising at least oneheating channel cast in the slab for transferring heat from a fluid passing through said atleast one channel to heat at least one surface of said slab, preferably uniformly heat onesurface of the slab. The heated surface is preferably the upper surface thereof once theslab has been positioned for use whereby the heating safeguards freezing of at least theupper surface of the slab does not occur. This may be beneficial for example if a buildingis to be mounted on the slab which thereby reduces detrimental effects of both the slaband the building. For example, both the slab and the floor of a building standing on theslab may be heated thereby reducing detrimental effects of moisture and humidity. Thismay be advantageous e.g. with respect to othenNise unheated warehouses or otherbuildings.

According to one embodiment, the water supply and purification unit comprises a caissonfor collection of separated fractions originating from the drained water. According to oneembodiment, by the term "water supply and purification unit" is meant any type ofconnection for supply of water and The term caisson is meant to include any type ofcontainer divided in compartments in which compartments the various separated fractionsare stored and which when filled will be subject to an emptying procedure whereby thecompartments are emptied. Such emptying procedure is suitably performed by a suction arrangement, preferably arranged on a truck or other vehicle allowing for regularremoval thereof and continuous use of the purification unit.
According to one embodiment, the water supply and purification unit have connectionsand couplings for electricity, water supply, and water drain for water purified in apurification unit integrated in the unit. Such connections are simply coupled or connected to stationary water supply means and plugged into available power outlets for electricity.
According to one embodiment, the insulating layer comprises at least one thermallyinsulating layer having a thickness ranging from 30 mm to 500 mm.
According to one embodiment, the heating channels are interconnected betvveen adjacentconcrete slabs to transfer heat in one single loop, preferably by means of a jointconfigured to be connected to ends of the heating channels.
According to one embodiment, said at least one first duct and said at least one secondduct are made of concrete. Preferably, gaskets such as rubber gaskets are arranged totighten joints between concrete slabs and said at least first duct to prevent leakage.According to one embodiment, said at least one first duct is removably arranged to said atleast t\No reinforced concrete slabs, for example by means of bolted joints such as screwsor similar means. According to one embodiment, said at least one second duct conveysdrained water to said purification unit.
According to one embodiment, said at least one first and said at least one second ductsare slanted and interconnected to convey water to the purification unit. According to oneembodiment, said at least one first duct is configured to convey water directly to thepurification unit whereby one end thereof is connected to inlet means of the purificationunit. The purification unit is preferably arranged to separate solid particles such as coarseparticles or sludge such as sand particles and gravel from soluble, miscible andimmiscible liquids such a water and oil and other hydrophobic substances such as variousorganic compounds.
According to one embodiment, the purification unit is arranged to separate at least 95 wt%or at least 99 wt% of organic material from the purified water.
According to one embodiment, the arrangement comprises 4 to 8 vehicle platforms. Thisthus provides for 4 to 8 vehicles being washed at the same time.
According to one embodiment, the slabs of the arrangement are provided with elevationsalong the external sides thereof except for the vehicle entrance side to prevent water fromdraining to the surrounding ground.
The invention also relates to a method for installing a movable car Wash arrangementaccording to any one of claims 4 to 16 comprising a) preparing an area of the ground adapted for installation of the car washarrangementb) mounting the arrangement according to any one of claims 4 to 16 on theprepared area such that at least said vehicle platform is substantially at thesame level as the surrounding ground to facilitate vehicle entrance theretoc) connecting Water supply and electricity from permanent supply means to the water supply and purification unit.
By the term "drained water" is meant used washing water drained substantially from theconcrete slabs and caused to be conveyed to said at least one first duct betvveen the tvvoslabs forming the vehicle platform. The term "drained water" is thus meant to includewater containing impurities initially adhered on the vehicle to be washed as well as anychemicals added during the washing or released from the vehicle such as degreaser, carschampoo, car wax, polishes, phosphates, surfactants, fatty substances or any otherchemicals such as oils etc.
According to one embodiment, said at least two concrete slabs are joined to said at leastone first duct by means of screws.
According to one embodiment, the platform for water supply and purification unitcomprising a caisson for collection of separated fractions is preferably arranged at a levelranging from 40 to 100 cm below the ground, for example 50 to 70 cm below the groundsuch that the upper portion of the caisson is at the same level as the ground. Theplatform may likewise be arranged on ground level. However, said at least one first ductand optionally said at least one second duct are slanted such that drained water can flowto and enter a first compartment of the caisson by gravity. While drained water flows viasaid at least one first duct and optionally via said at least one second duct, solid materialsuch as coarse and fine particles will settle to some extent before reaching the caisson.Eventually, at some suitable point in time, e.g. while the vehicle wash is temporarily notused, the ducts are cleansed to remove remaining settled solid material. According toone embodiment, said at least one second duct is formed as a pipe or comprises a pipeportion or is connected to a pipe connected to a caisson. Preferably, said at least onesecond duct is a pipe which has a length corresponding to the length and/or width of bothslabs of the vehicle platform. An advantage of such at least one second duct being a pipeis that it prevents inflow of rain water. Preferably, the second duct is designed towithstand a vehicle running over it. The material of the second duct must thus beselected accordingly. A further advantage of the second duct, especially when largerlevels of drained water is produced is that solid particles such as sludge may settle therein addition to the first duct. Preferably, said at least one second duct is openable to allowfor suction or removal of settled solid particles in other ways. Preferably, such at leastone second duct has a circular, rectangular or square-shaped cross section, preferablycircular cross section. According to one embodiment, the cross section of such at leastone second duct ranges from 0.2 to 2 m2, e.g. 0.2 to 1.5 m2, preferably from 0.3 to 0.7 m2,most preferably from 0.4 to 0.6 m2. By the use of these cross section, volumes forsettlement of solid particles may amount to at most about 10 m2. According to oneembodiment, the second duct may be comprised of a plurality of modules having a length in the range of e.g. 0.5 to 1.5 m to enable convenient transport thereof. The modules of the second duct may thus easily be mounted, demounted and transported. According toone embodiment, the caisson comprises a first compartment in which the drained waterenters via said at least one first duct or via said at least one second duct. ln said firstcompartment, coarse solid material still suspended in the drained water is separated bysettlement and/or filtration. The caisson preferably comprises a second compartmentseparated from the first compartment by means of a filter separating coarse solidmaterial. Drained water passing the filter separating said first and second compartmentsof the caisson will thus comprise a considerably reduced amount of solid material, e.g.sand, gravel, clay etc. Preferably, the caisson further comprises a third compartmentseparated from the second compartment by means of a filter. Drained water permeatingthe filter will be further purified from especially fine particles still suspended in the drainedwater. The cutoff of the filters can be selected according to needs depending on flowsthrough the filter, capacity of the purification unit, average concentration of remainingsolids suspended etc. Preferably, drained water is conveyed, e.g. by pumping thereof, toa separate purification unit connected to the third compartment, e.g. via a conduit forfurther purification including removal of metals such as heavy metals including lead,cadmium, zinc, chromium, nickel, and copper. The metals are preferably separated fromthe drained water by means of an electrochemical process whereby the metals areprecipitated, e.g. as hydroxide salts in a weak acidic or neutralized catholyte. Example ofelectrochemical processes for removal of metals such as heavy metals include electro-deposition, electrocoagulation, electro-flotation and electro-oxidation. Also further meansfor purification may be applied such as ion-exchange, membrane filtration such asreverse osmosis. Preferably, an electrochemical process is used in the purification unitsince such process has been found to enable handling of high levels of drained water. lnthe third compartment, in addition to drained water, e.g. oily or fatty and otherhydrophobic substances can be entrained.
As such hydrophobic substances are not miscible with water, they will over time form aseparate hydrophobic phase having a lower density than the aqueous phase,hydrophobic substances can to a large extent be separated from the aqueous phase andwill thus not be entrained as drained water is conveyed to the purification unit. Minorentrained amounts of hydrophobic substances may, however, be separated in thepurification unit by means of filtration such as ultrafiltration or adsorption, e.g. by meansof activated carbon.
According to one embodiment, the caisson comprises a fourth compartment separatedfrom the third compartment. Separated metals such as heavy metals or salts thereof,such as hydroxide-based salts, can be stored, at least temporarily, in the fourth compartment following separation thereof in the purification unit. Such metals, heavy metals or salts thereof may then at a suitable time, e.g. when the fourth compartment hasbeen filled, be conveyed from the fourth compartment to a suitable plant for rewinning ortreatment thereof. Preferably, drained water having been finally treated in the purificationunit can be conveyed to a municipal treatment plant since it does no longer contain anyremaining toxic levels or unhandled amounts of pollutants.
According to one embodiment, merely electricity, water supply means, and means forconveying purified water is connected to the arrangement. Should it be desired to movethe arrangement, all parts including ducts and concrete slabs being demountable couldbe easily transported to another site for remounting thereof to set up the washingarrangement again. The water supply and purification unit and the caisson could likewisebe easily transported to another site without any further need to restore anddecontaminate the ground, for example soil where it has been used.

Detailed description of the drawinqs Figure 1 shows a caisson which is arranged adjacent a reinforced concrete slab asfurther described herein. The caisson is typically produced of the same material(concrete) as the further concrete slabs. The dimensions of the caisson may vary andcan be designed in accordance with the dimensions of the vehicle platform slabs. Thenumbers of compartments 1a, b, c, d can be at least tvvo but preferably at least three orat least four as in figure 1. The compartments 1 illustrate collection of separated fractionsseparated from the drained water. A water purification unit is preferably mounted on topof the caisson which thus treats the used drained water. ln a first compartment 1a, and bymeans of separation technology, solid particles such as course sludge such as gravel,big particles, sand etc are collected. ln a second compartment 1b, finer solid particles areseparated and stored, while in a third compartment, oily and fatty substances are stored.ln a fourth compartment 1d, metals such as heavy metals are stored having beenseparated from water having been purified in the purification unit as described herein.Purified water having passed the various treatment steps and thus purified fromsubstances and compounds originating from the washing process is conveyed from thepurification unit via conduits to a municipal waste water treatment plant or the like.
Figure 2 shows roof 2 and a supporting structure attached thereto such as vertical beams3 attached in turn to the concrete slabs (not shown). Horizontal supporting beams 4 arealso shown.
Figure 3 shows two concrete slabs 5a, 5b in cross section between which a duct isarranged and attached to the lower portion of the sides of the concrete slabs 5a, 5b,preferably by means of screws securing the concrete slabs to the duct 6. Below the concrete slabs 5a, 5b, three layers of insulating material 11 arearranged.
The insulating layer facing the ground can typically be styrofoam as well as any furtherlayers. The insulating layers are normally positioned under the ground such that theupper surface of the concrete slabs are on the same level as the surrounding ground.The concrete slabs are slightly inclined such that water may flow towards the duct leadingwater to a second duct arranged to conduct water to the purification unit. The concrete slabs are preferably cast with slab edges such that they prevent leakage to thesurrounding areas. Figure 4 shows a cross section of a concrete slab 1 being reinforced by reinforcement means.
Figure 5 shows a heating channel 10. Figure 6 shows a heating channel running througha cross section of a concrete slab 5a, 5b.
Point of in|et 13 and point of outlet 14 are illustrated. Point of outlet for heat transfer is connected to an adjacent heating channel of an adjacent concrete slab (not shown).
Figure 7 shows four vehicle platforms (pairs of concrete slabs), two on either side of anon-shown caisson at which a water purification plant as well as machinery for supply ofwater is arranged, as well as sewage and electricity connections. The vehicle platformsare arranged adjacent to each other and are preferablyjoined to one another by meansof screws or the like. Water protecting edges are provided to prevent leakage of any water to the surroundings from the vehicle platforms.
