Definitions

  • the sieve section comprises a plurality of ring elements arranged on top of each other.
  • the ring elements are provided with distance elements determining thedistance between adjacent ring elements, the distance elements being formed as projections and recesses of stepwise heights and depths, respectively, or as mutually collaborating wedge units so as to allow an arbitrary setting of the ring distance.
  • the present invention relates to a fountain (bored) well that is designed to be placed in a hole drilled into the earth for pumping a liquid and that comprises a silt pipe at the lower end of the bored well, an extension pipe constituting the top section of the well, and a sieve section arranged between these, which sieve section is fitted with a pump, from which, on the other hand, a piping is arranged to the drainage point of the liquid, whereby the sieve section comprises several rings or equivalent positioned on top of each other, the mutual distances of which rings are determined by means of distance elementslocated on the rings and corresponding to each other.
  • the well which is located in a hole drilled into the earth (see FIG. 1), comprises a silt pipel, a sieve section 2, and an extension pipe 3. Inside the sieve section, a pump 4 is located, from which a piping leads to the drainage point of the water.
  • the water in the earth layers has access to the pumping space through the sieve section 2.
  • the slit size of the sieve pipe and the length of the sieve section are determined. This is why, from a good sieve pipe, light and easy adjustability of the water slit and possibility ofjoining the components are required;
  • the sieve pipes at present in use are made, among other things, of wood, ceramic materials, metal or plastics, and as extension pipes havebeen used steel or plastics pipes with threaded or flanged joints. In all of the above constructions it has not been easy to change the slit size of the sieve section but it has usually been constructed as fixed.
  • a purpose of the present invention is to avoid ;the above disadvantages and to produce an ever more eff cient fountain well.
  • a bored .well, according to the invention is mainly characterized in that the distance elements are formed as projections and recesses of stepwise heights and depths, respectively, or as mutually sensibletin g wedge units so as toallow any desired setting of the ring distance.
  • FIG. 1 shows, as'has already come out, a schematic view of a well according to the invention.
  • FIG. 2 shows, on an enlarged scale and as a partial cross section, the sieve section of the well of FIG. 1.
  • FIG. 3 shows, a partial section of one arrangement of rings of the sieve section of the well according to the invention.
  • the well pipe system consists of an extension pipe, a silt pipe 1, a
  • joint band 9 a body or framework 10 of the sieve section 4, and of adjustment rings 1 1, 12 around the body, made of various plastics by means of various manufacturing techniques (FIG. 2).
  • the water slit 19 is in the sieve pipe 4 according to the invention adjustable with sufficiently small steps or continuously within a certain range.
  • the sieve units and the extension pipes 3 can be joined simply and rapidly to any required length. Under these circumstances, the size of the slit 1'9 may be determined at the installation site, and one basic unit is adequate for storage. In this construction it is possible to make the water slit 19 more favourable for the water flow. By means of shaping it is also possible to reduce the blocking of the water slit by gravel. By manufacturing the entire system out of plastics, corrosion, decaying etc. troubles are avoided. Moreover, the friction coefficient of plastics is low, and so the silt carried from the soil by water does not block the sieve pipe construction.
  • the extensionpipe 3 is shaped so that its components are partly inserted into each other and that a groove 7 is formed at the joint.
  • the extension pipe accommodates a slot 8 at the groove -7, through which slot the locking band 9 is inserted into the groove 7.
  • the sieve section 4 consists of a body or body framework 10, around which adjustment rings 11 and 12 are piled.
  • the top section of the body 10 has a relieved thread section 13, and the adjustment rings 11 and 12 are tightened by means of a nut 14 adapted to the thread'section.
  • the top and bottom section of the body 10 has jointing units similar to those in the extension pipe 3.
  • the bottom end of the sieve section accommodates a silt pipe I, as which in the system according to the present invention, for example, an extension pipe 3 is suitable.
  • the bottom end of the silt pipe is closed by a plug 15.
  • FIG. 3 shows one arrangement of adjustment rings 11 and 12.
  • Ring 11 has on the surfach 16 recesses 17 of different depths, into which the projections 18 on the ring 12 are fitted.
  • FIG. 4 shows another arrangement of setting the water slit l9.
  • the ring 11 is fitted with a wedgeshaped recess 20 that the grooves or is otherwise roughened and the ring 12 is fitted with a wedgeshaped projection 21 that matches the recess 20.
  • a well pipe system according to the invention is assembled so that an extension pipe 3 (FIG. 2) is closed with a plug 15, after which it is suitable as a silt pipe 1.
  • a desired number of sieve section bodies 10 are joined by means of locking band 9.
  • the extensionor silt pipe has a flange 22, on top of which sieve rings 11 and 12 are placed in positions required by the necessary water slit.
  • the pile of rings in this way assembled is tightened bymeans of a nut 14 at the top end of the body 10.
  • FIGS. 5 and 6 show an additional embodiment of the invention.
  • FIG. 5 shows the sieve pipe as viewed from above and FIG. 6 the sieve rings.
  • the adjustment rings 24 have, with uniform distances, on both sides of the ring, circumferential wedge faces 26 and projecting faces 25.
  • the rings 24, which are in themselves identical, are arranged on top of each other so that the wedge face sections 26 of the rings are on every second ring narrowed in one direction and on every second ring in the opposite direction.
  • the inner face of each ring 24 has a pin 27 that can be accommodated to guide grooves 28 on the outer face of the body framework 10, which grooves are located asymmetrically in relation to each other. These guide grooves 28 are preferably accommodated with an evenly increasing phase transfer A in relataion to each other.
  • a sieve section arranged between the silt pipe and the extension pipe and comprising a plurality of ring elements arranged on top of each other, the ring elements being provided with distance elements determining the distance between adjacent ring elements, the distance elements being formed as mutually collaborating wedge units so as to allow an arbitrary setting of the ring distance, said wedge units being formed as wedge-faced recesses on the top face of the ring and as corresponding wedgeshaped projections on the face of the next ring, and the recesses and projections having wedge-shaped side faces which are accommodated substantially tangentially in relation to the circumference of the ring;
  • piping extending from the pump to a drainage point for the liquid.
  • a sieve section arranged between the silt pipe and the extension pipe and comprising a plurality of ring elements arranged on the top of each other, the ring elements being provided with distance elements determining the distance between adjacent ring elements, the distance elements being formed as mutually collaborating wedge units so as to allow an arbitrary setting of the ring distance, said wedge units comprising wedge-shaped side faces arranged onto the ring elements, preferably both on the top face and on the bottom face of the ring elements, said side faces being tangential in relation to the circumference;
  • piping extending from the pump to a drainage point for the liquid.
  • a well according to caim 2 further comprising a framework around which the ring elements can be arranged, guide grooves arranged vertically on the outer face of the framework and asymmetrically in relation to each other, said guide grooves being accommodated with an evenly increasing phase transfer (A) in relation to each other.
