  • A bottom of the milled slot, which may also be referred to as a sole, defines the depth of the milled slot. A first face and a second face define the length of the milled slot. The length of the milled slot is limited in the area of the first end face by an obstacle. An obstacle is a wall or a fence or a tree or a rock or a property boundary or another earth collector device or the like. At least the first end of the slot is formed by the soil. As a result, the first end face is not formed by an obstacle located in the ground.

  • The ground collector has a slot milled into the ground having a length, a width and a depth. A ground collector device of the ground collector is arranged in the milled slot.
  • The ground collector has another milled slot in the ground with another, arranged in a further slot Erdkollektorvorrichtung.
  • A first face and a second face define the length of the milled slot. The first face of the milled slot abuts the other milled slot. As a result, the first slot and the second slot do not intersect.
  • The milled slot is formed to the other milled slot at an angle other than 180 °. Preferably, the angle is adapted to an angle of the property boundaries. For example, the angle between the milled slot and the other milled slot is 90 °.
  • Another aspect of the invention is a router for milling a slot in the ground.
  • The mill has a milling arm with a chain cutter. The chain cutter is guided over an upper deflection and a lower deflection. Preferably, the chain cutter on a chain on the milling means - such as bits and / or knives or the like - are arranged.

Advantageously, the Räumerarm is adjustable in the intermediate position between the first position and the second position. Preferably, the cutter has a hydraulic system for driving the Räumerarms.
  • In the first position, the reamer arm is adjustable behind the cutter arm for clearing. The Milling and broaching takes place in a first milling path of the milling arm in the forward direction.
  • In contrast, the Räumerarm is not adjusted in the second position behind the cutting arm, but the Räumerarm is adjustable to a second position outside a collision area. In the second position, the second cutting path of the cutting arm takes place in the reverse direction. The milling arm can be adjusted in a milling position for the largest milling depth. The collision area is defined in the milling position for the largest milling depth above the lower deflection. In the collision area - without the adjustment of the Räumerarms from the collision area out - a collision between the Räumerarm and an end face of the slot to be milled slot is possible. Such a collision could hinder the milling process or damage the reamer.

  • In 2 is a ground collector device 200 shown schematically. In the 2 illustrated earth collector device 200 can be filled with a medium (not shown), which serves to transport heat energy to a heat pump. For this purpose, the earth collector device 200 of the 2 a pipe 210 , For example, a plastic pipe 210 , on. The pipe 210 has two connection areas 230 for example, for connection to a distribution node. The earth collector device 200 is flat and has a smaller width B2 relative to the height H2 and length L2. In the embodiment of 2 extends a carrier 220 about the height H2 of the earth collector device 200 , The earth collector device 200 extends over an area which is defined by the height H2 and length L2 and thus by the largest dimensions (H2, L2) of the earth collector device 200 is defined. The plane shape of the earth collector device 200 causes a much smaller compared to the length L2 and depth / height H2 width B2 of the Erdkollektorvorrichtung 200 , A planarity of the earth collector device 200 is not required. The width B2 gives the measure for the narrow end face 201 and the narrow longitudinal side 202 the earth collector device 200 ,
  • The earth collector device 200 is preferably formed dimensionally stable. For example, the earth collector device 200 a rigid, rigid construction of a solid conduit body for the medium. The earth collector device 200 of the 2 However, it is in the form of a Erdkollektormoduls whose conduit 210 from a continuous flexible plastic tube 210 that is on a multi-part support 220 . 221 is applied. A module is a prefabricated unit that can be delivered as a unit to the construction site for erection. The modularity allows, depending on environmental conditions, such as soil conditions, dimensions, etc., the dimensions of the earth collector device 200 adapt.
  • The pipe 210 is laid as a continuous loop. Under a continuous loop is understood that within the Erdkollektorvorrichtung 200 the pipe 210 has no branch, distributor or the like. The as a continuous loop on the support 220 . 221 positioned pipe 210 can therefore also be referred to as a pipe coil. The tube can be filled with an example, liquid heat transfer medium as a medium for energy transport to the heat pump.
  • Inserted into the ground, allows the Erdkollektorvorrichtung 200 a good heat coupling on both main sides of the earth collector device 200 to the ground. The earth collector device 200 is intended for a heat pump. For this purpose, the earth collector device 200 by means of the connection areas 230 connected to the heat pump via supply lines. The earth collector device 200 has such a dimensional stability that - especially during the erection of the earth collector - sections of the flexible plastic pipe 210 can be kept at a distance to each other. The attachment of the on the support 220 . 221 laid flexible plastic pipe 210 causes the maintenance of the geometric shape of the pipe laying, such as a spiral or the like. The plastic pipe 210 is preferably high pressure crosslinked. The plastic pipe 210 is preferably on the carrier 220 . 221 laid without crossing.
  • In the embodiment of 2 is by means of clamping the plastic tube 210 in grooves of the carrier 220 . 221 a dimensional stability of the entire Erdkollektorvorrichtung 200 causes. The carriers 220 . 221 are advantageously formed of wood, in which the grooves are milled, for example. The earth collector device 200 has as a carrier a plurality of spaced carrier elements 220 . 221 on. The carrier elements 220 . 221 are not interconnected. The carrier elements 220 . 221 are dimensionally stable, such as spruce wood trained. The earth collector device 200 gets its strength from the attachment of the plastic tube 210 on the support elements 220 . 221 ,
  • The earth collector device 200 is preferably for the following embodiments of 1 . 3a . 3b . 3c and 5 used. However, other ground collector devices (not shown) may also be used, for example, made of sheet-like plastic bodies, even without carriers.
  • To form a vertical ground collector, a number of ground collector devices are used 200 - for example, as in 2 presented - into the ground 500 introduced vertically. This is a narrow slit 100c in the soil 500 educated. 1 shows in a schematic sectional view of the formation of a slot 100c with the depth T1 in the ground 500 , The slot 100c is by means of a mobile Erdschlitzfräse 300 into the ground 500 milled. The earth slot cutter 300 has a milling arm 310 with a chain cutter on. Chisels and / or knives are arranged on a chain of the chain cutter.
  • The milling arm 310 is adjustable between a topmost position f1 and a lowermost position f2. While in the uppermost position f1 of the milling arm 310 is positioned substantially horizontally, in the lowest position f2 of the cutter arm 310 inclined downwards by the angle α. To the milling arm 310 between the uppermost position f1 and the lowest position f2, the Erdschlitzfräse points 300 a hydraulic drive on. Will the milling arm 310 driven by the chain cutter from the uppermost position f1 to the lowest position f2, the chain cutter mills the milling edge 160 the material of the soil 500 By moving the chain to the earth's surface 550 is transported. By adjusting the milling arm 310 from the topmost position f1 to the lowest position f2, the arch is created 150 , By simultaneous milling and procedure of the Erdschlitzfräse 300 in the forward direction Dv may be the slot 100c be generated with the depth T1. The movement of the chain cutter is during the milling process by a lower deflection 311 the chain and an upper deflection 312 set the chain.
  • The slot 100c has a first (depth) area a for positioning the ground collector device 200 on. The first area a has at least the height H2 of the earth collector device 200 on. Above the first region a, a second (depth) region b may be provided which corresponds, for example, to the local frost depth. If above the surface of the earth 550 later weather layers (in 1 not shown), the second region b may alternatively be formed by these further layers.
  • The earth slot cutter 300 has a reamer 320 on, above the cutter arm 310 arranged and with the milling arm 310 from the uppermost position f1 to the lowest position f2 is adjustable. reamer 320 is arranged in the forward direction Dv behind the chain cutter and clears the material dissolved during the milling process of the soil 500 in the area of the chain cutter, so that the dissolved material is caught by the chisels and / or knives of the chain cutter and along the milling edge 160 also from the slot 100c is transported. The reamer 320 sticks out to the ground 110 of the slot 100c where the ground 110 of the slot 100c also as a sole 110 and the reamer 320 therefore also as Sohlenräumer 320 can be designated. Through the reamer 320 can the whereabouts of solved by the milling material in the slot 100c be significantly reduced.
  • In the formation of earth collectors, the length of a slot 100c in the soil 500 often limited by an obstacle. In 1 is an example of a boundary wall as an obstacle 510 shown in sectional view. However, other obstacles such as a building, a tree, or a property boundary may be the length L1 of the slot 100c limit.
  • As the earth collector device 200 In the first area a is arranged, the earth collector device must 200 due to the arc created during the milling process 150 from the wall 510 distanced - for example, with a distance of 1.5 meters - in the slot 100c to be ordered. In this case, this distance range only at increased expense for heat extraction from the ground 500 be used.
  • 3 shows a method by a schematic sectional view in which the Erdschlitzfräse 300 in both the forward direction Dv and in the forward direction Dv opposite reverse direction Dr is moved. In a first step 1 During the milling process, the milling arm becomes 310 pivoted to a low position. To the bow 150 of the 1 To avoid driving the Erdschlitzfräse 300 in a second step 2 in reverse direction Dr and mills the slot 100a towards the obstacle 510 , In order to enable a milling in the reverse direction Dr, the reamer 320 adjusted so that the reamer 320 not with the soil to be milled 500 collided. The second milling process in the step 2 can - as in 3a shown - to the obstacle 510 respectively. The material of the soil dissolved by the milling process 500 in a further process step - in 3a not shown - during a process in the forward direction Dv with the reamer 320 be cleared, with the Sohlenräumer 320 for clearing in a lowermost position behind the chain cutter is adjusted.
  • 3b shows a third step 3 in the lowest adjustment position f2 of the cutting arm in a schematic sectional view.
  • The earth slot cutter 300 of the embodiment of 3b has a milling arm 310 with a chain cutter on. The chain cutter is over an upper deflection 312 and a lower deflector 311 guided. The position f2 of the cutter arm 310 is adjustable to change the cutting depth. In 3b is the lowest adjustment position f2 of the milling arm 310 shown. The chain cutter has milling means, such as chisels and / or knives, mounted on a chain of the cutter arm 310 are arranged. By driving the chain of the cutter arm 310 the milling tools mill the soil 500 , In the third step 3 is the milling arm 310 adjusted to the lowest position f2, whereby by the method of the Erdschlitzfräse 300 in the reverse direction Dr the soil 500 mainly in the area of the lower deflection 311 is milled.
  • The earth slot cutter 300 has a reamer 320 with an adjustable reamer arm 321 on. The reamer arm 321 is adjustable between a first position and a second position and in intermediate positions between the first position and the second position.
  • For a first milling path of the milling arm 310 in the forward direction Dv - as in the 1 is shown - is the Räumerarm 321 in the first position behind the milling arm 310 to clean up on the sole 110 of the slot 100c adjustable. For a second cutting path of the cutter arm 310 according to the step 3 in 3b is the reamer arm 321 in a second position outside a collision area 10 adjustable. The second cutting path of the milling arm 310 takes place in 3b in the reverse direction Dr with the milling position f2 of the milling arm 310 for the largest milling depth.
  • For the second milling path is the Räumerarm 321 completely out of the collision area 10 swing out. The collision area 10 is above the lower deflection 311 Are defined. In this collision area would be without swinging the Räumerarms 321 a collision between the reamer arm 321 and one through the soil 500 formed end face 130 of the slot to be milled 100b possible, so that the milling path in step 3 would be limited by the collision.
  • In the embodiment of 3b is the position of the cutter arm 310 for adjusting the milling depth T1 of the slot 100b up to an angle of 60 ° with respect to the earth's surface 550 adjustable. The reamer arm 321 is between a first position behind the cutter arm ( 310 ) with an angle (β) of 180 ° and a second angled position with an angle (β) of 45 ° adjustable. An embodiment of the reamer 320 is to 4 explained in more detail.
  • By means of the Erdschlitzfräse 300 can a slot 100b according to 3c with a floor 110 and two substantially parallel main pages 120 and a first end face 130 and a second end face (not shown) into the ground 500 for positioning the earth collector device 200 be milled the earth collector. The first front page 130 gets through the soil 500 formed, as the first front page 130 has a substantially vertical edge. An obstacle - in the embodiment of 3c a fence 520 - is above the first area a of the slot 100c arranged and does not form the first end face 130 of the slot 100c , The slot 100c does not immediately border on a ground 500 however, its length L1 still gets through the fence 520 limited.
  • In a first milling process is - as in 1 shown - in the forward direction Dv the Räumerarm 321 to the ground 120 of the slot 100b adjusted so that material in the slot 100b through the reamer arm 321 is cleared in the forward direction Dv. In a second milling process in the reverse direction Dr is - as in the 3a and 3b shown - to form the predominantly vertical first end face 130 of the slot 100b the reamer arm 321 from a collision area 10 between the cutter 300 and the first front side 130 of the slot 100b adjusted. By means of the milling machine 300 becomes backward Dr until the first end 130 of the slot 100b Milled.
  • In the embodiment of the 3a and 3b become the formation of the predominantly vertical first end face 130 the first milling in the forward direction Dv and the second milling in the reverse direction Dr for successively milled depths of the slot 100b repeated. This causes the first end face 130 not smooth and ideally perpendicular, but with a wavy shape is formed, as in 3c indicated.
