Description
1 FORFARANDE FOR UPPTAGNING AV HAL SAMT INSTALLATION AV KOLLEKTORSLANG I HAL. 1 PROCEDURE FOR RECEIVING HALL AND INSTALLATION OF COLLECTOR HOSE IN HALL.
Tekniskt omrade Den foreliggande uppfinningen avser ett fdrfarande fOr upptagande av hal samt installation av kollektorslang i upptagna hal, i enlighet med patentkraven. Technical area The present invention relates to a method for accommodating a hall and installing a collector hose in a occupied hall, in accordance with the claims.
Teknisk bakgrund Under senare ár har det blivit allt mera vanligt forekommande att installera bergvarmesystem for att anvanda geotermisk varme vid uppvarmning av exempelvis byggnader. I samband med installation av bergvarmesystem borras ett eller flera hal i berg belaget vid platsen fOr uppforande av bergvarmesystemet. I det upptagna halet, eller halen, fors minst en kollektorslang, eller annan typ av kollektor, partiellt ned. Efter att kollektorslangen partiellt forts ner i halet ansluts denna darefter till en vanligen ovan mark belagen varmepump ingaende i bergvarmesystemet. Technical background In recent years, it has become increasingly common to install geothermal heating systems to use geothermal heat when heating buildings, for example. In connection with the installation of a geothermal heating system, one or more halls are drilled in rock covered at the site for erection of the geothermal heating system. At least one collector hose, or other type of collector, is partially lowered into the occupied tail, or tail. After the collector hose is partially continued down the tail, it is then connected to a heat pump, which is usually located above ground, entering the geothermal heating system.
Ett problem med upptagning av hal fOr kollektorslang och liknande i bergvarmesystem är att halen vanligen tas upp med tryckluftsdrivna borrutrustningar. Au anvanda befintliga borrutrustningar sasom tryckluftsdrivna borrutrustningar, vid borrningen, medfOr en risk att miljdfarliga amnen sasom exempelvis olja kommer ner i borrhalet och aft grundvattnet darigenom riskerar aft fOrorenas. A problem with picking up hay for collector hoses and the like in rock heating systems is that the haul is usually picked up with pneumatic drilling equipment. Using existing drilling equipment, such as pneumatic drilling equipment, during drilling, entails a risk that environmentally hazardous substances such as oil enter the borehole and the groundwater thereby risks being contaminated.
Andra problem i samband med upptagning av hal Rh- bergvarmesystem fdrorsakas av att berget vanligen inte nar upp till marknivá utan är belaget ett stycke under marknivan. Detta medfor att en del av halets strackning gar genom losare typ av mark sasom genom lera, sand eller liknande. For aft forhindra att material rasar in i halet, i relativt losa lager, mellan berget och marknivan utfors vanligen en infordring av halet med foderror eller liknande. Ett problem vid installation av foderror är att detta med befintliga anordningar och fbrfaranden tar lang tid (i forhallande till det foreliggande fOrfarandet) i ansprak. Ett ytterligare problem vid installation av foderror och liknande är att dessa bestar av rdr vilka svetsats samman, vilket medfbr att vasentligen langre tid atgar for sammanfogningen av foderroren an med anvandande av fcirfarandet i enlighet med den foreliggande patentansokan. Other problems in connection with the uptake of slippery Rh rock heating systems are caused by the fact that the rock usually does not reach ground level but is covered a bit below ground level. This means that part of the stretching of the tail goes through looser type of soil such as through clay, sand or the like. In order to prevent material from collapsing into the tail, in relatively loose layers, between the rock and the ground level, a feeding of the tail is usually carried out with feed pipes or the like. A problem with the installation of feed pipes is that this with existing devices and procedures takes a long time (in relation to the present procedure) in use. A further problem in the installation of casings and the like is that these consist of pipes which have been welded together, which means that a substantially longer time is required for the joining of the casings using the procedure in accordance with the present patent application.
Ett ytterligare problem med befintliga metoder for att installera bergvarme och liknade, fbrorsakas av aft foderroret lamnas kvar i marken efter att halet i marken tagits upp och 2 kollektorslangen installerats (anslutits) i halet. Kostnaden for foderroren, speciellt cm djupet ner till berget r stort fran markytan, bli darfor hoga eller mycket hOga. Det foreligger saledes ett behov av ett forfarande dar kostnaden for foderror kan minska. A further problem with existing methods for installing rock heating and the like is caused by the feed tube being left in the ground after the tail in the ground has been taken up and 2 the collector hose is installed (connected) in the tail. The cost of the feed pipe, especially cm deep down to the rock is large from the ground, therefore become high or very high. There is thus a need for a procedure where the cost of feed tubes can be reduced.
Ett ytterligare problem med att lamna kvar foderror i mark är att dessa riskera aft rosta sonder med efterfoljande problem med fororeningar i marken (rost mm). An additional problem with leaving feed tubes in the ground is that they risk rusting probes with subsequent problems with contaminants in the ground (rust etc.).
Kind teknik At borra hal i marken och i berg är sedan tidigare kant i ett flertal olika varianter av utrustningar och forfaranden. Exempelvis beskrivs i patentskriften SE527590 en borranordning for att borra hal i berg. Borranordningen i enlighet med patentskriften skiljer sig i vasentlig omfattning fran det foreliggande forfarandet och anordningen. Exempelvis innefattar konstruktionen enligt patentskriften inte en vattendriven hammare. Kind technique Drilling slips in the ground and in rocks has previously been an edge in a number of different variants of equipment and procedures.

Anordningen och forfarandet i enlighet med patentskriften skiljer sig i stor omfattning fran konstruktion och fbrfarandet i enlighet med den fOreliggande patentansokan. Patent specification SE531106 describes a variant of a sealing member for separating sections inside an elongate hall. The construction differs from that of the examined construction. For example, the patent does not describe a procedure for taking up a drilling rig in the ground. Furthermore, the patent does not include a method of casting the tail above the tan with concrete in accordance with the present patent application. patent specification SE429375 describes a variant of a method for utilizing heat energy in the well water from a drilled well hall. The device and the method according to the patent specification differ greatly from the construction and the method according to the present patent application.
I patentskriften SE391373 beskrivs en variant av en tatningsanordning for att avstanga fOrbindelsen mellan berghals delar pa skilda nivaer. Konstruktion i enlighet med patentskriften skiljer sig i stor omfattning fran konstruktion och fOrfarandet i enlighet med den foreliggande patentansokan. Exempelvis innefattar patentskriften inte ett motsvarande forfarande for anvandning av att ta upp borrhal respektive installera kollektorslang. Patent specification SE391373 describes a variant of a sealing device for shutting off the connection between rock neck parts at different levels. Construction in accordance with the patent specification differs to a large extent from construction and the procedure in accordance with the present patent application. For example, the patent does not include a corresponding method for the use of picking up a drill bit or installing a collector hose.
I patentskriften SE444127 beskrivs en variant av en tryckvatskedriven sankborrmaskin vilken innefattar en slagborrkrona. I patentskriften beskrivs inte ett forfarande i enlighet med den fOreliggande patentanstikan. 3 Andamilen med den foreliggande uppfinningen Det huvudsakliga andamalet med den fOreliggande uppfinningen är att skapa ett fOrbattrat forfarande och anordning vilken loser eller reducerar minst ett av ovan namnda problem. Andamalet uppnas med ett forfarande i enlighet med patentkraven.

The patent does not describe a method in accordance with the present patent. 3 Andamilen with the present invention The main object of the present invention is to create an improved method and device which solves or reduces at least one of the above-mentioned problems. The spirit is achieved by a process according to the claims.
Detaljerad besluivning av uppfinningen Foreliggande uppfinningen avser ett forfarande, fOr aft ta upp ett eller flera hal och i det upptagna halet (eller halen) installera minst en kollektor, i enlighet med den foreliggande patentansokan. FOrfarandet kan foretradesvis anvandas vid installationer av bergvarmesystem och liknande. Det ar dock tankbart aft forfarandet anvands i andra typer av applikationer och forfaranden eller delfiirfaranden. Detailed description of the invention The present invention relates to a method for removing one or more halos and installing at least one collector in the occupied halo (or tail), in accordance with the present patent application. The method can preferably be used in installations of geothermal heating systems and the like. However, it is conceivable that the procedure is used in other types of applications and procedures or sub-procedures.
Med kollektor avses i bergvarmeapplikation fciretradesvis kollektorslang eller liknande. I altemativa utforingsformer av bergvarmeapplikationer samt inom andra typer av applikationer ar det dock tankbart aft kollektom utgors av annan for andamalet lamplig kollektor. In collectors 'application, geothermal application refers to collectors' hoses or the like. In alternative embodiments of geothermal heating applications and in other types of applications, however, it is conceivable that the collector consists of another collector suitable for the spirit.
For genomfOrandet av fOrfarandet anvands sedan tidigare till stora delar kand och for andamalet lamplig borrutrustning. Exempelvis kan borrutrustningen innefatta en borrigg eller liknade. Unikt med den foreliggande utrustningen är att denna innefattar en slagenhet och/eller vibrationsavgivande enhet samt minst en tryckvatskedriven borrhammare (sankborrmaskin eller liknande) vilken fOretradesvis drivs av trycksatt vatten. For the implementation of the procedure, well-known drilling equipment has been used to a large extent in the past. For example, the drilling equipment may comprise a drilling rig or the like. Unique to the present equipment is that it comprises a percussion unit and / or vibration-emitting unit as well as at least one pressurized water-driven hammer drill (submersible drilling machine or the like) which is preferably driven by pressurized water.
Initialt forflyttas hela eller delar av den erforderliga utrustningen, for att genomfiira forfarandet, till den plats dar installationen skall utfOras. Initialt fOrs awn hela eller delar av den erforderliga mangden material till platsen fOr uppforandet av bergvarmeanlaggningen. Den utrustning och det material som forflyttas till arbetsplatsen är beroende av vilken av utforingsformema av det foreliggande forfarandet som skall utforas. Efter aft utrustningen forflyttats till platsen for anvandandet stalls denna upp pa ett sedan tidigare kant sat varfor detta inte beskrivs mera ingAende i derma patentansokan. Initially, all or part of the required equipment, in order to carry out the procedure, is moved to the place where the installation is to be carried out. Initially, all or part of the required amount of material is brought to the site for the construction of the geothermal heating system. The equipment and materials moved to the workplace depend on which of the embodiments of the present process is to be performed. After the equipment has been moved to the place of use, it is set up on a previously set edge, which is why this is not described in more detail in this patent application.
Med anledning av att berget vanligen inte nar upp till markniva och är belagen pa ett avstand fran marknivan stacker sig halet vanligen genom mark av losare karaktar sasom genom lera, sand eller liknande. FOr att forhindra att material rasar in i halet sker vanligen en infordring av halet med foderror eller liknande. Tidigare metoder for aft fOra ner foderror i marken har nackdelen av att dessa tar lang tid i ansprak att utfOra samt medfor att lera och liknande 4 sprutas runt omkring borrhalet. En unik del med det foreliggande forfarandet är att roret fors ner i marken med rotation av foderroret samtidigt som foderroret paverkas av slag (vibrationer) fran en i borriggen ingaende hammare (eller vibrationsavgivande enhet). Due to the fact that the rock usually does not reach the ground level and is covered at a distance from the ground level, the tail usually sticks out through soil of looser nature such as through clay, sand or the like. To prevent material from collapsing into the tail, the tail is usually fed with feed tubes or the like. Previous methods for lowering feed pipes into the ground have the disadvantage that these take a long time to carry out and involve clay and the like. 4 sprayed around the drill tail. A unique part of the present method is that the rudder is driven into the ground with rotation of the casing while the casing is affected by blows (vibrations) from a hammer (or vibration-emitting unit) entering the drilling rig.
Vid nedfOringen av foderroret anvands foretrddesvis en variant av en bonkrona med genomga.ende hal i centrum (paminnande om en halsag). I samband med att foderrOret halet en stor del av materialet i borrhalet trycks ut i omkringliggande mark. When lowering the casing, a variant of a bonnet crown with a continuous halo in the center (reminiscent of a neck saw) is preferably used. In connection with the feed pipe hauling a large part of the material in the drill haul is pushed out into the surrounding ground.
I fcirfarandet fOr att fora ner foderror i marken anvands foretradesvis foderror vilka kan kopplas samman och isdr. I det exemplifierande fOrfarandet sker detta genom att foderroren i sina andar är gangade. Den ena anden av foderroret innefattar utvandig gdnga och den andra anden av foderniret innefattar en invandig ganga. Genom detta kan en invandig gangad del i ett foderror och en utvandigt gangad del i ett annat foderror skruvas samman. I altemativa utforingsformer kan rOren kopplas samman med annan for dndamalet ldmplig teknik. Ett erforderligt antal foderror kopplas ihop och flirs (drivs) ner i market till det att foderroret nar berget. Roret fors dven ner en delstracka ner i berget. Vid fOrfarandet ldmnas awn en fOr andamalet ldmplig ldngd av det oversta foderror over markytan. In the procedure for lowering feed pipes into the ground, feed pipes are preferably used which can be connected together and ice dry. In the exemplary procedure, this is done by the feed tube in its spirits being grounded. One spirit of the casing comprises an external passage and the other spirit of the casing comprises an internal passage. Through this, an internally threaded part in a feed tube and an externally threaded part in another feed tube can be screwed together. In alternative embodiments, the tube may be coupled to another technique suitable for this purpose. A required number of casings are connected and flushed (driven) down in the market until the casing reaches the rock. The rudder is driven down a section into the rock. In the procedure, awn for the second dimension is allowed to be an adequate length of the top feed tube above the ground surface.
Efter att foderroret natt ner till berget, samt foretradesvis aven en delstracka ner i berget, fOrs en borr ned genom foderroret ned till berget. Med bonen sker darefter en upptagning av hal i berget till ett onskat djup. Unikt med det foreliggande fOrfarandet är att borrens rotation sker med en hydrauliskt drivenhet samt att slagfunktionen uppnas av en borrhammare, sankborrmaskin, eller liknande vilken exempelvis innefattar en slagborrkrona vilken foretradesvis drivs med trycksatt vatten. Detta 'nee& att det tidigare namnda problemet med risken av att Met fororenas med hydraulolja, eller andra oldmpliga amnen, vdsentligen inte langre foreligger. After the casing night down to the rock, and preferably also a section down into the rock, a drill is passed down through the casing down to the rock. With the nest, a slippage is then taken up in the rock to a desired depth. Unique to the present method is that the drilling of the drill takes place with a hydraulic drive unit and that the percussion function is achieved by a hammer drill, submersible drilling machine, or the like which for example comprises an impact drill bit which is preferably driven with pressurized water. This' nee & that the previously mentioned problem with the risk of Met being contaminated with hydraulic oil, or other obsolete substances, is probably no longer present.
Efter att det planerade (erforderliga) borrdjupet uppnatts fors en i forhallande till borrhalets djup ldmplig langd av kollektorslangen ner i borrhalet. Vid nedfOrandet av slangen ansluts minst ett tatande organ till slangen. Tatningen fors ner med slangen till en niva som är lamplig for andamalet. Tatningen dr avsedd att avdela borrhalet i minst en Ovre del och minst en nedre del. After the planned (required) drilling depth has been reached, an inexhaustible length of the collector hose is lowered into the drill tail in relation to the depth of the drill tail. When lowering the hose, at least one gripping member is connected to the hose. The seal is lowered with the hose to a level that is suitable for the spirit. The seal is intended to divide the drill tail into at least one upper part and at least one lower part.
Eller att slangen fEirts ner i halet och tatningen avdelat halet i berget i en Ovre och undre del fylls den Ovre delen med betong, cement eller annat for dndamalet lampligt tatande material. Or that the hose is lowered into the tail and the seal divides the tail into the rock in an upper and lower part, the upper part is filled with concrete, cement or other suitable material.
Efter att den Ovre delen av halet i berget tappts igen, tas foderroret upp ur halet. Halet genom det relativt losa materialet ovanfor berget fylls darefter av massoma kring halet. Vid behov sker en pafyllning av material vid halet. After the Upper part of the tail in the rock has been drained again, the feed tube is taken out of the tail. The tail through the relatively loose material above the rock is then filled by the masses around the tail. If necessary, a material is filled at the tail.
Efter aft ovanstaende delsteg utforts ansluts kollektorslangen ddrefter med kdnd telcnik till kand varmepump eller liknande ingaende i en bergvdrmeutrustning. After performing the above sub-steps, the collector hose is then connected with a known telecnik to a known heat pump or similar input in a rock heating equipment.
Efter aft fOrfarandet utfOrts fors foretradesvis utrustningen och eventuellt overblivet material frail platsen for borrhalets upptagande och installationsplatsen fOr kollektorslangen. . After the procedure, the equipment and any remaining material is preferably removed from the site for receiving the drill bit and the installation site for the collector hose. .
