Definitions
- the invention relates to a method as designated in the preamble of claim 1.
- the invention has for its object to reduce at least partly the drawbacks of the said known method.
- the method according to the invention has for this purpose the characteristic of claim 1.
- the invention also relates to and provides a structure built with use of the invented method. If the steel profiles are removed from the ground after arranging of the foil (14) the costs of this method are reduced considerably.
- Figure 2 Steel sheet piling profiles 3 are struck into the ground to form sheet-pile walls 4 to enclose a construction excavation area 5.
- FIG. 3 The sheet-pile walls 4 are anchored in transverse direction by means of grouted anchors 6 or by means of cross struts 7 indicated with dashed lines.
- the ground is excavated from the construction excavation area 5 to a level 8 lower than the floor level 9 of the carriageways 2 and higher than the bottom edge 10 of the sheet-pile walls 4.
- the excavation level 8 is a thickness of the sand layer 13 deeper than the laying level of the foil 14.
- the laying level of foil 14 is such that the water pressure under foil 14 is smaller than the total pressure of water and ballast material which is present above the foil 14 for arranging.
- FIG. 4 Support shields 11 are placed which are lined on their inner sides with a drainage layer 99.
- Figure 5 In the channels 18 between sheet-pile walls 4 and support shields 11 are arranged water-inhibiting layers 12 and in addition a sand layer 13 of classified sand, without sharp portions, is arranged above the level 8.
- FIG. 6 A long watertight foil 14 is laid on the sand layer 13, wherein its side pieces 15 are folded over.
- the spreading out flat of foil 14 takes place for instance by means of sinking under its own weight in combination with cables 16 which are already pre-arranged through the support shield 11 (see figure 5).
- the side pieces 15 are erected against support shields 11 by means of cables 17 or optionally in that the ends of cables 16 are first moved to the edges 98 which are then pulled outward in horizontal direction by cables 16 and in that the edges 98 are thereafter pulled upward by means of cables 17.
- Figure 7 Ground is arranged evenly up to floor level 9 inside the foil 14 and in the channels 18, preferably such that the ground level inside the foil is continually slightly higher than in the channels 18, wherein the necessary drainage pipes 20 are incorporated in this ground.
- Classified sand is herein arranged against foil 14.
- FIG 8 The space inside foil 14 above the drainage pipes 20 is pumped dry. Draining takes place simultaneously in the channels 18 by means of drainage pipes 90.
- the water level in channels 18 is always kept slightly lower than the water level inside foil 14.
- the water level is likewise kept lower than the water level inside foil 14, this making use of the drainage mat 99 and provisions (not drawn) in the support shield 11.
- Supporting ground is arranged above floor level 9 as a natural slope or, preferably, supported by means of concrete retaining walls 22.
- Figure 9 The sheet-pile wall profiles 3 can be pulled out of the ground and be re-used.
- the structure 1 is then finished by laying of the carriageways 2 and sewage pipes 23.
- the structure 1 is built, if it is long, in a number of construction excavations 25 which are located in succession and which are for instance 200 m long and mutually separated by means of partitions 26 (figures 10, 11, 14, 15).
- partitions 26 At the position of a partition 26 a connecting excavation area 27 is created between sheet-pile walls 4 by driving in sheet-pile wall profiles 33 to form transverse walls 34.
- This connecting excavation area 27 is divided into two spaces 29 by driving in sheet-pile wall profiles 35 to form an intermediate wall 36.
- a partition 26 can be realized by means of the removable door 40 of figures 16 and 17.
- a special U-shaped sheet-pile wall profile 41 is then employed in which a U-shaped coupling profile 42 is received slidably which is provided with flanges 43 for coupling on an edge of a foil 14 by means of strips 44 and bolts 45.
- A'door 40 is arranged in the coupling profile 42 slidably and sealed by means of sealing strips 46.
- the door 40 is slid downward in two sheet-pile wall profiles 41, while being held in place on the two coupling profiles 42 and on a coupling profile 48 which is situated on the bottom edge of the door 40, until this coupling profile 48 comes to support on sand layer 13.
- both foils 14 are fixed to coupling profiles 42 and 48 the door 40 can be pulled up therefrom.
- a support shield 11 is not used but the side pieces 15 of foil 14 are held in place in a different way.
- the folded edge 50 is drawn tighter by means of cables 51 which run through tubes 52 which are fixed to the sheet-pile wall 4, while the top edges 53 of the side pieces 15 are erected by means of cables 17 and thereafter held fixedly on means 55 present above the ground.
- the sheet-pile wall 4 can be removed and only the cables 51 remain behind in the ground.
- the created structure 1 can contain a carriageway for road or rail vehicles, can also contain a storage space for separating the stored material from groundwater.

Description
Claims (9)
- Method for building in the ground a structure (1) with a floor (2) located at a floor level (9) under ground level, wherein in at least one construction excavation area (5) ground is excavated to a level that is lower than the floor level (9), wherein after excavation of the ground a construction space is closed off inside the construction excavation area (5) with a watertight foil (14), for instance of plastic, and wherein drainage provisions (20) are arranged under the floor level (9), characterized by the following steps:the construction excavation area (5) is closed off with at least one construction excavation wall (4) of steel profiles (3) forming sheet-pile walls (4);the ground is excavated from the construction excavation area (5) to a level (8) lower than the floor level (9) of the carriageways (2) and higher than the bottom edge (10) of the sheet-pile walls (4);support shields (11) are placed;in the channels (18) between sheet-pile walls (4) and support shields (11) are arranged water-inhibiting layers (12);a watertight foil (14) is laid in the space between said support shields (11), wherein its side pieces (15) are erected against said support shields (11) such that the construction excavation area forms a pan which is sealed off by said foil (14);ground is arranged up to floor level (9) inside the foil (14) and in said channels (18), wherein the necessary drainage pipes (20) are incorporated in this ground; andthe space inside foil (14) above the drainage pipes (20) is pumped dry.
