Definitions
- the invention relates to a method for driving a sheet pile wall as defined in the first part of claim 1.
- the detection pin used therein is in the form of a bolt having an enlarged foot that bears on the lower edge of the sheet pile portion surrounding the lock space.
- the detection line is fastened laterally to said enlarged foot.
- the invention provides a method of the type above referred to which distinguishes from the well-known method by the features of the second part of claim 1.
- the invention also relates to a sheet pile for use with the above method, said sheet pile having the features as defined in claim 3.
- the sheet piles 1 and 2 have their longitudinal edges la and 2a respectively in mutual engagement in a well-known manner.
- a "lock space" 3 In the lower end of this lock space, which has a substantially triangular cross-section, a detection pin 4 is inserted and a detection line 6 is anchored in the lower end face of the pin 4.
- the detection line extends upwardly along the outer side of the lock space wall 1b (fig. 2).
- the detection pin 4 shown in fig. 1 is of a type according to the prior art above referred to.
- the detection pin according to the invention, which is intended to be substituted for the detection pin 4 in fig. 1, is shown in fig.
- Fig. 2A illustrates the case, in which the sheet pile 2 is "properly engaged” and will - while driving is continued - get with the lower end of its longitudinal edge 2a in engagement with the upper end of the detection pin 4 (4') as a result of which the latter will be finally expelled from the lower end of the lock space 3 of the pile sheet 1, while the tack weld(s) 5 are broken off.
- This situation can be observed above ground through the detection line 6 becoming slack.

Description
- The invention relates to a method for driving a sheet pile wall as defined in the first part of
claim 1. - Such a method is known from NL-A-7908262. The detection pin used therein is in the form of a bolt having an enlarged foot that bears on the lower edge of the sheet pile portion surrounding the lock space. The detection line is fastened laterally to said enlarged foot.
- The invention provides a method of the type above referred to which distinguishes from the well-known method by the features of the second part of
claim 1. - The invention also relates to a sheet pile for use with the above method, said sheet pile having the features as defined in
claim 3. - The invention will be hereinafter further described by way of example with reference to the accompanying drawing.
- Fig. 1 is a perspective view showing how two adjacent sheet piles are entering into mutual engagement, wherein a detection pin of a known type is used;
- fig. 2A is a cross-sectional view, along the line II-II in fig. 1, in which a second sheet pile, that "runs in the lock", is indicated by dash-dotted lines;
- fig. 2B is a cross-section as shown in fig. 2A, in which dash-dotted lines designate a second sheet pile, which is about to "run out of the lock";
- fig. 3 is a perspective view of a detection pin according to the invention, in the form of a sleeve that is clamped on the end of a steel wire cable, said detection pin being intended to be used as a substitution for the detection pin shown in fig. 1; and
- fig. 4 is a cross-section through the lower end of a sheet pile and a detection pin of fig. 3 inserted therein.
- In fig. 1 two trapezium-shaped sheet piles of a well-known design are illustrated in a diagrammatic manner and indicated by the
reference number sheet pile 1 has already been driven to the desired depth into the ground, whereas thesheet pile 2 has to be driven further. - The
sheet piles - Along the free longitudinal edge la of the
sheet pile 1, i.e. the longitudinal edge, which has to be brought into engagement with the adjacentlongitudinal edge 2a of thenext sheet pile 2 to be driven, there is provided a "lock space" 3. In the lower end of this lock space, which has a substantially triangular cross-section, adetection pin 4 is inserted and adetection line 6 is anchored in the lower end face of thepin 4. The detection line extends upwardly along the outer side of thelock space wall 1b (fig. 2). Thedetection pin 4 shown in fig. 1 is of a type according to the prior art above referred to. The detection pin according to the invention, which is intended to be substituted for thedetection pin 4 in fig. 1, is shown in fig. 3 and 4 and is in the form of a metal sleeve 4' which is clamped on the distal end of a steel wire cable 6' functioning as a detection line. This sleeve 4' may be readily clamped onto the cable 6' by means of a simple clamping tool and is secured in thelock space 3 by means of one ormore tack welds 5, which are provided via the lock space slit 3a. - Fig. 2A illustrates the case, in which the
sheet pile 2 is "properly engaged" and will - while driving is continued - get with the lower end of itslongitudinal edge 2a in engagement with the upper end of the detection pin 4 (4') as a result of which the latter will be finally expelled from the lower end of thelock space 3 of thepile sheet 1, while the tack weld(s) 5 are broken off. This situation can be observed above ground through thedetection line 6 becoming slack. - Fig. 2B illustrates the case, in which the
sheet pile 2 has partially "run out of the lock" and will - while continuing driving - remain just out of engagement with the detection pin 4 (4'), as a result of which the latter will remain within the lower end of thelock space 3 of the last drivensheet pile 1. - This situation can be observed aboveground through the
detection line 6 being kept tensioned. - In the event the second sheet pile to be driven has a shorter length than the first driven
sheet pile 1, so that the lower end of the second sheet pile will not reach the detection pin within the lock space of the driven sheet pile, the difference in length may be compensated by a filling rod of a corresponding length which is dropped into the lock space of the driven sheet pile.
Claims (3)
- A method for driving a sheet pile wall by successively driving sheet piles (1, 2), of which the profiled longitudinal edges (1a; 2a) are slidingly engaging one another, into the ground, wherein sheet piles (1, 2) are driven, which are provided below, at the free longitudinal edge (1a; 2a), with a detection pin (4') inserted axially from below into a lock space (3) confined by said longitudinal edge (1a; 2a), the lower end of said pin (4') being connected to a detection line (6') extending upwardly along the outer side of the lock space (3), characterized in that use is made of a detection pin in the form of a sleeve (4') that is clamped on the distal end of a steel wire cable (6') functioning as a detection line, said sleeve (4') being secured in the lock space (3) by a break-connection (5).
- A method according to claim 1, characterized in that the break-connection is effected by providing one or more tack welds (5).
- Sheet pile, the profiled longitudinal edges (1a; 2a) of which confine a lock space (3) for engagement with the longitudinal edge (2a; 1a) of an adjacent sheet pile, a detection pin (4') being axially inserted within the lower end of the lock space (3) along one of the longitudinal edges (la; 2a), said detection pin (4') having its lower end connected to a detection line (6'), characterized in that use is made of a detection pin in the form of a sleeve (4) that is clamped on the distal end of a steel wire cable (6') functioning as a detection line, said sleeve (4') being secured in the lock space (3) by one or more tack welds (5).
