Definitions

  • the present invention relates to a method for retaining soil after excavation of a nente soil, in particular for the passage of a trench pipe.
  • the embankment of the cells between the panels is retained with the help of grids anchored in the ground by appropriate means, for example pins.
  • FIGS. 1 and 2 there is shown respectively in cross-sectional view on the line of greatest slope and in cross-sectional view a trench 1 for passage of a pipe 4.
  • line 4 is put in place at the bottom of the excavation.
  • a stop block 6 is made at the bottom of the slope in which the pipe 4 is embedded and the profile and anchoring of which are calculated as a function of the existing conditions of the structure.
  • the next step is to set up at the bottom of the excavation. on either side of the pipe 4.
  • one or more lateral drains 5 intended for the evacuation of water likely to enter the trench.
  • the drains exit laterally from the trench at intervals which depend on the slope and the expected flow, for example every 50 meters.
  • the last drain (s) pass through the stopper block 6 through a hole made when the latter is produced.
  • a film of permeable material is placed over the length of the trench, for example a film formed from a permeable / nonwoven plastic material known under the commercial designation "BIDIM" or the equivalent, so that the film passes over the different transverse panels PI, P2. P3. P4.P5 as shown in Figure 1, and is supported, in intermediate intervals, on the embankment R1 already placed in the trench.
  • BIDIM permeable / nonwoven plastic material
  • the residual volume of the trench is filled with the rest of the embankment, as indicated in R2 in FIGS. 1 and 2. Then, to hold this embankment R2 in the abovementioned cells, there is a grid, at its upper part, for example in galvanized iron, the tension of which is ensured by means of pins, as indicated at 8 in FIGS. 2 and 3. It is not necessary for this grill to be very resistant to decomposition and it is sufficient for it to resist until consolidation of the land, for example about 2 years in a temperate climate because it is estimated that after such a period the vegetation has progressed enough to then ensure the maintenance of the R2 embankment.
  • these panels are arranged overall with an approximately vertical orientation but, to facilitate the flow of rainwater and avoid the effects of gullying and erosion, these purlins are arranged obliquely relative to the direction of the trench.
  • This obliquity is usually materialized by the angle ⁇ in Figure 3.
  • This angle o (can be between 90 and 75 °.
  • the orientation of the panels is chosen to prevent a return of runoff water to the trench
  • the spacing e of the panels is determined according to the existing conditions of the structure, that is to say in particular rainfall, slope of the ground, nature of the soil, characteristics of the film, etc.
  • the installation height of the panels in the grooves 9 is approximately between a quarter and a third of the height of the excavation. and we also take into account t, to determine this installation height. of the conditions of the structure.
  • a deflector extension is provided thereon. highlighted in 11 in FIGS. 2 and 3.
  • This extension can be constituted by a simple board which is fixed at the top of the panel P 2 , P 3 ... and which is slightly embedded in the land in the vicinity of the excavation, as indicated in 11A in FIG. 2. It is also possible to join the panel and the deflector extension in the form of a monobloc assembly.
