Definitions
- the subject of the present invention is a new process perfected for the realization of thin walls in the ground.
- Such walls can have for example ten of centimeters thick and a height of about twenty meters.
- EP-A-0 513 461 European Patent No. 91402175.3
- EP-A-0 513 461 European Patent No. 91402175.3
- a vibration is pressed into the ground beam or sheet pile which has at its lower part a device to inject a grout at low pressure which, after solidification, constitutes the thin wall while we send horizontally at the bottom of the beam at least one jet of liquid at very high pressure directed substantially in the plane of the wall to achieve.
- very high pressure liquid is meant according to the present description a liquid sent at pressures understood by example between 200 and 600 kg per square centimeter.
- the present invention relates to improvements to the process described above which allow to significantly improve the quality of the sealed wall obtained and to increase its speed of execution.
- the subject of the present invention is a method for to make watertight walls in the ground, of the type in which we sink vertically by vibration and we go up a sheet pile in the ground the along the route of the wall to be made, by injecting at low pressure, at the base of the sheet pile, a conventional grout which, after injection, the thin wall, a jet of liquid at very high pressure substantially in the plane of the wall and towards the part of the wall to be made, and a jet of liquid at very high pressure towards the part of the wall that has already been made, characterized in that the very high pressure liquid that is sent to the bottom of the sheet pile during its descent and during its ascent consists of a fluid grout based on water, bentonite, additives and cement, while injecting at the base of the sheet pile, above injection of liquid at very high pressure, during its descent and ascent, a thick conventional grout based on water, bentonite, cement, additives and an aggregate which communicates its consistency to it, by the fact that the very high pressure jet directed towards the part of the wall already
- sheet pile is meant according to the present description a rigid metal profile, generally made of steel, which is pressed into the ground successively along the route of the wall that you want achieve.
- adjuvant is meant, according to the present description, liquid or powdery products including low dose incorporation in a grout causes changes in certain properties of grout, fresh or hardened.
- the adjuvants can also be constituted by any other product intended to adapt the rheology of the grout to the conditions encountered on site (for example anti-freeze products).
- the grout injected at low pressure at the bottom of the sheet pile during the threshing and during the ascent of the latter is of a consistency relatively large so as to be able to provide resistance, flexibility, impermeability and resistance to erosion of the wall.
- the grout which is injected at very high pressure in the wall already formed during the rise of the sheet pile is a very fluid grout made only from water, cement, bentonite and adjuvants, so that one could legitimately ask if the injection at very high pressure of such a grout would not lose to the wall already realized its essential characteristics of resistance, flexibility, impermeability and resistance to erosion.
- the axis of the nozzles arranged at the bottom of the sheet pile which send the fluid grout under very high pressure is tilted slightly downwards, preferably 8 20% from the horizontal.
- the nozzles which do not send grout at very high pressure during the different phases of the process, however, allow a low flow of grout to flow at low pressure to avoid blockage.
- the sheet pile 1 is intended to be inserted into the floor to make the thin wall 2.
- a vibratory hammer or vibrobatter 3 activated for example by a powerful hydraulic motor which vibrates the sheet pile 1 so that it sinks into the ground.
- the vibratory hammer 3 is supported by the mast 4 of a machine lifting 5 schematically shown.
- Sheet pile 1 is guided in its descent by a device attached to the lifting device 5 which, for simplicity of the drawing, has not been shown.
- FIG. 1 represents the threshing or jacking of sheet pile 1, as shown in arrow F.
- a conventional grout thick for thin wall is sent under low pressure by a nozzle 6 located below the sheet pile while a fluid grout 7 is sprayed at very high pressure below the sheet pile in downstream direction, i.e. to the right in the drawing, direction of the ground in which the wall is to be made.
- FIG. 2 shows an embodiment particular of the lower part of the sheet pile 1 which presents a central core 8 and two wings 9.
- the central core 8 has a thickness reinforcement 8 has in its lower part. It is the same wings 9 which present building extra thicknesses 9a.
- the wing 9 on the left and its reinforcement 9 a extend downwards substantially beyond the central core 8.
- a fin 10 is attached to the outside of the left wing of the sheet pile 1, in the extension of the core 8, so as to be move into part 2 of the thin wall that has already been made and to stabilize the path of the sheet pile during its descent.
- the sheet pile 1 is guided so as to be preferably situated at the limit between the part of the wall 2 which has already been carried out and the land to be sealed which is to the right of the drawing.
- a thick slurry of the type usually used to make the sealing walls, base of water, bentonite, cement and aggregate is injected by the double nozzle 6 at a pressure of a few tens of kilograms per square centimeter.
- This thick grout injection is essentially intended to facilitate penetration into the soil of the sheet pile under the effect of the vibrations communicated to it.
- a fluid cement-based grout, bentonite, additives and water is injected at very high pressure, for example at 600 kg per square centimeter, through nozzle 12 towards the right, towards the ground in which the wall must be carried out.
- the axis of the nozzle is inclined about 15% downward with respect to the horizontal.
- fluid grout is also sent to the nozzle 13 which is directed towards the wall 2 already done, but only at a pressure of a few kilograms per square centimeter and only to avoid plugging the line 15 and nozzle 13.
- the fluid grout which is sent under very high pressure by the nozzle 12, has the effect of disintegrating and to permeate the ground below the sheet pile, which facilitates and strongly accelerates the descent of the latter by realizing the excavation in which the wall will be made.
- the mode of implementation of the invention which comes to be described allows to realize in the ground, at a speed important, a wall of excellent quality with good continuity and good sealing.
