Definitions

  • the invention relates to a ground retaining wall as described in the preamble of claim 1.
  • Such a ground retaining wall is known from NL-B-6514655 or the article of Travaux no. 512, October 1977, particularly page 42, Fig. 13.
  • the screen is formed by a series of adjacent dam wall profiles.
  • dam wall profiles are of a heavy structure, because the level of the ground anchors is frequently high, for example, because the ground anchors have to be arranged above a high-tide level or else above an obstruction present in the ground.
  • the screen may, as an alternative, consist of a concrete retaining wall, which has then to be resistant to high bending load.
  • the invention provides a ground retaining wall having a less heavy and hence cheaper screen.
  • the ground retaining wall according to the invention is characterized according to at least one ground retaining wall standing at a distance from the screen at the back side thereof, that an at least partly ground-free space is left between the standing wall and the screen such that the groundspace is left between the standing wall and the screen such that the ground level at the side of the wall facing the screen is at a substantially lower level than that its other side, and that the ground level difference acting on the wall is transmitted as a force acting against the top end of the screen by the aid of pressure transmitting means interposed between the top end of the screen and the wall.
  • a retaining wall prestressed by a bending moment is disclosed in DE-B-1209067, wherein a weight of ground and is supported by a support element arranged at the front side of the retaining wall. This support element pulls at the top end of the retaining wall in the direction towards the front side and pressed backwards against the retaining wall at lower level.
  • the screen of this retaining wall is loaded by a great vertical load. The combination of vertical load with bending load results in the requirement of strong profiles at the screen.
  • the above mentioned article also discloses a ground retaining wall in which is provided a second screen bearing at its top an element bridging the two screens. As the second screen is not considerably loaded by a ground level difference said bridging element does not transmit a pressure from the second screen onto the first. No ground anchors are provided in this prior art construction.
  • Fig. 22 and 23 of said article a ground-free space is provided at the back side of the screen which ground-free space is bridged by a horizontal construction element.
  • Fig. 23 teaches that the horizontal ground pressure in the direction of the screen should be prevented e.g. by inclined piles.
  • the teaching of said Fig. 23 is also given in FR-A-380 552 and FR-A-737124.
  • the supporting means When the supporting means are formed by concrete cover plates, they may, in addition, serve as a road pavement or a quay.
  • the ground 2 exerts a pressure on the screen 4 opposite the pressure of the water 8, whereas the screen is retained by ground anchors 6 having a tractive force P.
  • Fig. 2 illustrates the line of moments due to the forces exerted on the screen 4, the line of moments being designated at the area of the anchor heads 51 by M a , the maximum potential moment being designated by M max .
  • the weight of the dam wall profiles 3 is a function of M max .
  • ground retaining wall according to the invention is distinguished from the known ground retaining wall described above as follows.
  • a wall 54 is standing at a distance b from the screen 4, said wall bearing on the part of the screen 4 located above the level A with the aid of pressure- transmitting supporting means 60.
  • the space 14 between the standing wall 54 and the screen 4 is substantially free of ground and only contains air.
  • the supporting means 60 may consist of a plurality of pressure bars of a framework, but preferably they are formed by reinforced concrete cover plates 10 having longitudinal ribs 57 engaging the top edges 58 and 59 of the dam wall profiles 3 and of the wall 54 respectively.
  • the wall 54 is standing on a concrete foundation 13 and retains the top layer 55 of the ground 2.
  • the pressure q exerted by the top layer 55 on the wall 54 is balanced out by the pressure force K of the supporting means 60 and the tensile force S of the anchor cables 9, which connect anchor heads 61 with the ground anchors 6. Owing to the application of the force K the line of moments of Fig. 4 is obtained, where M max is considerably lower than that of Fig. 3. Moreover, owing to the ground-free space 14 the overall pressure of the ground 2 to be retained is appreciably reduced. As a result the dam wall profiles 3 of the screen 4 in Fig. 3 may be of considerably lighter weight than those of Fig. 1.
  • the ground retaining wall 15 of Fig. 5 is distinguished from that of Fig. 3 in that the standing wall 63, the cover plates 64 as well as the foundation slabs 65 of the wall 63 form part of reinforced concrete longitudinal profiles 66, which are deposited on the dam wall profiles 3 and engage by a rib 67 the top edges 58.
  • the cover slabs 64 are located in this example at a lower level than the top surface 68 of the ground 2, so that the dam wall profiles are shorter.
  • the ground retaining wall 17 of Fig. 7 is distinguished from the ground retaining wall 15 in that the longitudinal profiles 18 are substantially L-shaped and the foundation of the standing wall 70 is formed by piles 20.
  • the ground retaining wall 19 of Fig. 9 is distinguished from that of Fig. 7 in that the ground-free space 14 is enlarged by leaving out ground in a space 71 below the water level 72, as a result of which the ground pressure to be retained is further reduced.
  • anchor means 51, 5 and 6 are arranged above the level of the water 8, which is usually required for these anchor means.
  • the screen 4 may, as an alternative, consist of a reinforced concrete wall or concrete wall elements.
