Description

The present invention relates to a tank

  rainwater for collecting and storing rainwater

  pitations. Rainwater tanks are used more and more to store runoff precipitation water collected on consolidated surfaces such as roofs, courtyards etc. Such rainwater tanks are preferably constructed to be buried but in

  exceptional circumstances they can also be po-

  freely located outside buildings.

  The known rainwater tanks consist of

  smells of a tank to collect and store the water of preci-

  pitations; this tank is a cylinder in one piece

  with a conical or flat cover. These parts are pre-

  s15 ference made of concrete, so that the cylindrical tank

  has a significant weight. For the installation of such a

  Servoir requires a powerful crane. In addition, the storage and transport of cylindrical tanks requires

place, which makes them more expensive.

  Also known are rainwater tanks comprising a plastic tank. A thin-walled plastic tank does not have the necessary strength, so either a tank with

  thick wall, which translates into a high material cost

  vé, or a tank reinforced by ribs, which cor-

  responds to high manufacturing costs.

  The present invention aims to develop a rainwater tank, the manufacture, storage and

transportation is advantageous.

  To this end, the invention relates to a tank

  rainwater of the defined type characterized in that it comprises

  takes a lower half-shell and an upper half-shell, the two half-shells being of a material bonded by cement and having a section which decreases from an open side, these half-shells being joined symmetrically with respect to a horizontal separation plane, by their open side, as well as a well reported on the ceiling surface of the upper half-shell and surrounding the manhole,

  crossing this ceiling surface.

  The main feature of the invention is

  is to manufacture a tank in a material bound by ci-

  ment, in particular in concrete, in concrete reinforced with steel or in fiber concrete, which makes it possible to achieve a

  very solid tank at an advanced material cost

  tageux. The tank consists of an upper half-shell

  and a lower half-shell whose section goes in dimi-

  naked. The two half-shells are joined in a horizontal junction plane to form the tank. The subdivision into two half-shells halves the weight of the parts compared to that of a conventional tank in one piece. This facilitates transport and handling which can be

  executed with a smaller crane. The realization of half

  hulls with a decreasing section allows stacking of demicoques, which corresponds to extremely space-saving storage and the loading surface of transport vehicles, preferably trucks, can thus be used

in optimal conditions.

  Preferably, the two half-shells have an essentially identical form of construction. This results in a particularly inexpensive manufacturing,

  because the same mold can be used to make two half

cockles.

  According to other characteristics of the invention

  tion: - the two half-shells are of frustoconical shape, - the two half-hulls have internal support surfaces to be stacked, - the support surfaces consist of support consoles formed on the internal wall of the half-shells shells, - between the edges to be joined of the two half-shells, a joint is placed in a groove provided in the edges, the two half-shells are screwed by their joined edges,

  - handling loops are screwed in half

  shells, - the manhole of the ceiling surface of the upper half-shell is covered by a manhole cover receiving a down pipe, - a filter installation is housed in the well, the installation of filter comprises a receiving bowl receiving water and a filter through which water passes from the receiving bowl into the tank, - the receiving bowl relates concentrically to the receiving pipe and the filter is a tubular filter which concentrically housed in the receiving bowl,

  - the receiving bowl has a tubular end piece

  centered with a perforated wall receiving the downpipe and the tubular filter, - a bypass pipe is provided in the well to

  the outside of the receiving bowl and leads directly

  in the drain, - the tank can be connected to at least one other tank and these different tanks communicate by a

  link planned near the bottom.

  On the tank made by assembling the two half-shells, a well is placed which is preferably also made of concrete, concrete reinforced with steel or

  fiber concrete or any other building material

  cement bonded. The well can also be made of plastic, in particular reinforced plastic.

by glass fibers.

  The well serves as an entry well and is used for tra

  regular service and cleaning of the rainwater tank. The well can also receive all of the functional elements such as, for example, the filter, the dirt-retaining installations, the feed, or the like. As these functional elements are all placed in the well, they do not influence the shape of the

  tank itself, which is advantageous for the construction

tion of the two half-shells.

  The present invention will be described below in more detail using an embodiment shown schematically in the accompanying drawings, in which: - Figure 1 is a vertical section of the rainwater tank, - the FIG. 2 is a top view of the rainwater tank,

  - Figure 3 is a vertical section corresponding to the fi-

  gure 1, with an exploded view of the functional elements of the well,

  - Figure 4 is a detail view showing the connection between-

  be the upper part and the lower part of the tank

  see, - Figure 5 is a vertical section showing the stacking of the lower and upper demicoques of the tank, - Figure 6 is a vertical section of an embodiment of a

  tank for an installation composed of several

  towels. According to Figures 1 to 3, the rainwater tank consists of a tank to collect and store the

  precipitation waters. This tank consists of a half

  lower shell 10 and an upper half-shell 12. The de-

  lower half-shell 10 and upper half-shell 12 are in

  concrete, preferably steel-reinforced concrete or reinforced concrete

  bres. The half-shells 10, 12 have in principle the same shape at

  know that of a truncated cone whose large base is ou-

  green. The two half-shells 10, 12 are assembled symmetrically with respect to the horizontal plane of separation, by

their respective open side.

  According to the detail view of FIG. 4, the half

  shells 10, 12 are preferably screwed to each other.

  For this, each of the two edges of the half-shells 10, 12 of-

  before coming against each other involves, so

  laying, a profiled groove receiving a seal 14 preferably an elastomeric seal Threaded sleeves 16 are integrated in the edge of the lower half-shell 10 according to an equiangular distribution. In the embodiment shown, there are six threaded sleeves 16 with an angular interval each of 60. At the end engaged in the

  half-shell 10, the threaded sleeves 16 have a transverse bore

  versal 18 receiving a reinforcing iron 20 of the reinforced concrete of the half-shell 10. The threaded sleeves 16 are thus secured to the half-shell 10 to ensure high tensile strength. The threaded sleeves 16 can also be used

  res on the anchoring means and the latter are then integrated

  rigged in the half-shell 10 as shown, for the

  upper half-shell 12, with the anchoring means 30.

  Tubular sleeves 22, through, vertical

  wedges are provided in the edge of the upper half-shell 12

  at appropriate angular positions and radius.

  When placing the upper half-shell 12 on the half

  lower shell 10, the tubular sleeves 22 are axially aligned with the threaded sleeves 16. Threaded tie rods 24 are placed in the tubular sleeves 22 and they are screwed

  in the threaded sleeves 16. On the end of the tie rods

  strips 24 projecting from the upper edge of the upper half-shell

  lower 12, a nut 26 is screwed to pull the edges of the two half-shells 10, 12 one against the other; the seal 14 seals between the half-shells 10, 12. The frame 20 of the

  reinforced concrete of the upper half-shell 12 surrounds the man-

upper chons 22.

  Consoles 28 are produced inside the half-shells 10, 12. In the embodiment shown, three consoles 28 are provided, each offset by an angle of 120 relative to each other. These consoles each leave from the bottom or the ceiling of the respective half-shell 10, 12 and extend substantially over the half-height of the long pairs of the inner wall. The half-shells 10, 12 can be stacked one inside the other by virtue of their frustoconical shape as indicated on the left of FIG. 5

  for the lower half-shells 10 and on the right for the

  upper mid-shells 12. In this stacked state, the half

  shells 10, 12 superimposed are supported axially by the con-

  soles 28. This prevents the stacked half-shells 10, 12

  may get caught in each other, and this could

  mid-hulls 10, 12 and optimal use of the surface of

  loading onto a transport vehicle.

  then the upper half-shell 12, on the lower half-shell

  10 and we assemble. This has the advantage of not being

  shells 10, 12. It is also possible to install the

  mid-hulls 10, 12 in the already assembled state and, in this case, the crane must lift, by the anchoring means 30, the entire tank formed by the half-hull 10 and the half-hull

  upper 12. However, in this case, the crane must be pre-

  view for the total weight of the tank. But in this solution

  The two half-shells 10, 12 are of construction

  identical and can thus be cast in the same mold.

  Unlike the lower half-shell 10, the upper half-shell 12 has a manhole 32 in the center of its upper surface. The manhole 32 is closed by a manhole cover 34 preferably made of material

plastic or stainless steel.

  In addition, outside the manhole 32, the upper surface of the upper half-shell 12 includes a tube passage 36 produced by casting and which can also be made of plastic or stainless steel. The tube passage 36 is used to introduce conduits such as for example

  a suction line for collecting rainwater from stock-

  ée in the tank, electric cables for the display of the level or similar means, inside the tank

  12, we place a well preferably made up of a ring 38 with a cone 40 and a cover 42. The diameter of the well 38 is greater than that of the manhole 32 made.

  in the upper half-shell 12, and the well ring 38 in

  coaxially rotates the manhole 32. The cone 40 placed on the well ring 38 decreases the diameter of the well to the diameter of the cover 32 closing the upper manhole. The well is preferably also made of concrete, reinforced concrete, concrete

  with fibers or other building materials linked by ci-

  The well serves as access to the reservoir for the tra-

  worth inspection and cleaning. It is obvious that the

  well can be adapted for example by complementary rings

  and the rainwater tank filter.

  In the middle of the manhole cover 34, we have

  a downcomer 44 which descends axially into the reservoir

  see. The downpipe 44 opens directly, above

  from the bottom of the lower half-shell 10, in a bowl

  46. The collected rain passes into the tank through the downpipe 44 and the length of the downpipe

  44 ensures that rainwater always arrives in the reservoir

  see below the water level. The deflecting bowl 46 deflects the water leaving at the base of the downpipe 44 so that this water rises. This ensures that the water reaches the tank as calmly as possible, causing as little turbulence as possible in the water.

  In the center and above the cover 34 of the manhole, a receiving bowl 48 is placed having a preferably circular edge facing upwards. In the middle and at the bottom of the receiving bowl 48, there is a tubular end-piece, coaxial with a perforated wall. The tubular end piece 50 is attached to the end of the downpipe 44 which protrudes from the cover 34 of the manhole. A filter is placed in the tubular end piece 50. This filter preferably has the form of a cylindrical tubular filter 52, placed coaxially in

  the tubular end piece 50. The tubular filter 52 projects vertically

  setting the top of the tubular end piece 50.

  A supply pipe 54 passes radially

  the wall of the ring 38 of the well, above the edge of the cu-

  receiving vette 48. The supply pipe 54 opens radially inside to reach the collecting bowl.

reception 48.

  The supply pipe 54 is used to conduct the precipitation water collected by the covered surfaces (roofs, floors, etc.) into the tank. Water passes through the supply pipe 54 into the receiving bowl 48. Dirt particles contained in the precipitation water accumulate in the receiving bowl 48. The water escapes from the bowl 48 to through the tubular filter 52 or the wall

  perforated from the tubular end piece 50 and the filter 52, for

  In the event of heavy precipitation, the water arrives through the supply pipe 54 with a powerful jet which strikes

  radially the tubular filter 52. This impact creates pro-

  water jets passing over the edge of the tank

  reception vette 48 and can no longer arrive in the tank. To avoid this, a chute 56 is preferably provided at the edge of the receiving bowl 48,

  upper cover chute 58 collects the events

48.

  Outside the receiving bowl 48, there is a bypass pipe 60 housed in the upper surface of the half-shell 12; this bypass pipe exits from the side and at the top of the upper half-shell 12, towards the outlet 62. The outlet is preferably provided with a siphon and a grid preventing the passage of rats. When in case of very heavy precipitation, the amount of water arriving through the pipe

  54 exceeds the capacity of the receiving bowl

  tion 48 and tubular filter 52, the excess water passes

  over the edge of the bowl 48 through the discharge pipe

  rivation 60 to arrive directly in the drain 62. Similarly, if the filter 52 is blocked and if the water can no longer

  pass through the downpipe 44, this water passes directly-

  ment in the drain 62 by the bypass pipe 60.

  To clean the filter installation, after

  lifting the cover 42 from the well, the tubular filter 52 and the receiving bowl 48 can be extracted from the top of the

  well and clean it. When the receptacle bowl is removed

  removal by the manhole and the cone 40 of the well.
