Description
A method of making a sheet-pile wall and a wall made by said method.
This invention relates to a method of making a retaining wall, in part~cular a composite wall composed of piles, driven into the ground in spaced relationship and sheet piles interconnecting said piles and connected to each other and to said piles by means of interlocks.
Such walls, in which the piles consist of sin-gular or composite double-T sections interconnected by sheet piles of bent cross-sectional shape are known in the art.
The double-T sections are driven into the ground with their flanges extending in the longitudinal direction of the wall.
The disadvantage of using such sections in making a composite wall is that, as a result of the fact that such sections, as viewed in cross-section, are extre-mely rigid in the direction of their web, but transversely thereto, i.e., in the longitudinal direction of the wall exhibit very little rigidity, the sections are apt to deviate from the desired directions as they are being driven into the ground. Such deviations cannot be taken up by the interlocks, and as a consequence subterraneous leakages occur, the repair of which is extremely expensi~ve in practice.
It is an object of the present invention to avoid this drawback.
For this purpose, in a method as defined ~
the opening paragraph, after the piles have been driven in, these are interconnected by a flexible screen wh~ch is placed as a whole by either dri~ing in all the sheet piles , ~- ~,, simultaneously or driving them in incrementally and alternately at least two at a time, the sheet piles being placed in such an arrangement that, in horizontal section, ~rrespective coupling points are spaced on a curve.
The direction of curvature will be selected in dependence upon the specific application so that the screen is pre-domimantly subjected to tensile forces from ground and/~or water and/or air present on opposite sides thereof.
If necessary, accoraing to the invention, the ground between the driven-in piles may be loosened before the flexible screen is driven in.
As the coupling points lie on a curved line, i.e. theinterlocks lie on a curved cylindrical surface, the sum of the clearance present in the interlocks imparts sufficient flexi ~ity to the screen for compensating for major deviations in pile orientation both longitudinally of the wall and at right angles thereto.
In order to minimize such pile deviations right from the start, the piles used for making the composite wall according to the present invention are preferably tubular piles.
According to the invention, the screen compri-ses at least two, but preferably at least three piles to ensure good flexibility.
The invention also relates to a compo~ite sheet-pile wall made in accordance ~ith the invention.
In a preerred em~odi~ment o~ the inventi~on, the composite sheet-pile ~all according to th2 i~nventi~on comprises tubular piles driven into the ground in spaced relationship, which piles are on their ~acing sides equipped with one or more interlock elements, with a oflexible sc~een of sheet piles extending between the piles, said sheet piles being interconnected by interlocks, which screen comprises at least two sheet piles and is connected to the pile interlock elements, said interlock elements and the interlocks between the sheet piles extending in a curved surface.
For optimum strength and flexibility of the screen, according to the invention, the sheet piles may each be of curved cross-sectional configuration.
Furthermore, according to the invention, the interlock elements connected to the tubular piles may be of duplicate construction so that a second screen may be driven in between two successive tubular piles, which second screen is curved away from the first screen. The space between the screens can be emptied and thus be made accessible for inspection in an easy manner, or it may be filled with concrete.
One embodiment of the invention will now be described, by way of example, with reference to the accompanying drawing.
The drawing shows in plan view two driven-in tubular piles 1 and 2 provided on opposite sides with a double interlock element 3. The interlock elements need not be in exact diametrical opposition to each other, It '~
4;3t33 is sufficient for them to be provided on the facing sides of the piles. Rxtending between the piles is a flexible screen 4, which is curved towards the water side, designated by W. Screen 4 is composed of a plurality of sheet piles 5, which preferably each have a cross-sectional shape with a radius of curvature approximately correspond-ing to that of the entire screen 4. The sheet piles 5 have clutches 6 and 7, a clutch 6 being adapted to be slipped into a clutch 7 to form a water retaining lock. At the lateral edges of the screen, clutches 6, 7 engage with one half of the double interlock elements 3 secured to tubes 1, 2. In the plane of drawing, the facing interlock elements 3 and locks 6, 7 of screen 4 are located on a line curved towards the water side W. According as the curvature of the screen 4 is greater, and according as the screen comprises a larger number of sheet piles 5, the flexibility of the screen is greater. The use of double interlock elements 3 makes it possible to provide a second screen 4', shown dotted in the drawing, between piles 1 and 2 for inspection purposes, which screen 4' is curved towards the land side designated by L. The space between screens 4 and 4' can be emptied for inspection of screen 4. Screen 4' can be removed again after the inspection or, if desired, the interspace may be filled with concrete.
Before screen 4 is driven in, the ground between piles 1 and 2 may be loosened, which may be effected in known manner using sand drills or otherwise.
fi: -`
` S, 3~33 The piles may be anchored in the conventional manner.
It is clear that th.e invention is not limited to the em~odiment described. Thus various pile configura-tions and sheet pile configurations may be used, but the advantage contemplated by the inventi~on is best realizible using round piles, in particular tubular piles, and as many flat, slightly curved sheet piles as possible, at least two. By virtue of its curved configuration and because the sheet piles can pivot relatively to each other in the interlocks, the screen can adapt itself to possible non-parallellism of th.e piles and, if any deformation stres-s occurs at all, this will be a, slight, torsional stress in the individual sheet piles, which will not lead to the locks being forced.
