Abstract

A method of pile driving a first tubular metal liner 1 into the ground by a vibrator and driving a second concentric metal liner or tool 3 into the ground inside the first liner, the second liner or tool having a clack valve 4 pivoted at its lower end, or alternatively a core retainer, withdrawing the second liner or tool from the bore hole with the clack valve resting on a stop on the liner, or with the spoil held in the liner by the core retainer; to cause the spoil to be lifted with the second liner from the bore hole and discharging the spoil from the liner. Apparatus for carrying out the method is also described. <IMAGE>

Description

SPECIFICATION An improved method of pile boring and apparatus thereof This invention relates to an improved method of pile driving and apparatus therefor.
It has been proposed heretofore in pile driving apparatus to bore a hole and to insert a metal liner into the bore after filling the liner with concrete and then withdrawing the liner, the core of earth being removed by a drill or auger.
According to the invention the method comprises driving a first tubular metal liner into the ground by a vibrator and driving a second concentric liner or tool inside the first liner, the second liner or tool having a clack valve or core retainer at its lower end, means for withdrawing the second liner or tool from the bore hole with the clack valve or core retainer resting on a stop or retainer to cause the spoil to be lifted with the second liner or tool from the bore hole and allowing the spoil to be discharged from the second liner or tool.
Apparatus for carrying out the method comprises a first liner in the form of a metal tube driven into the ground by a vibrator mounted on the upper end of the liner, a second concentric tubular liner or tool driven into the ground by the vibrator, a clack valve or core retainer for heavy soil mounted at the lower end of the second liner or tool to leave the bore in the tube open during insertion into the ground and on withdrawal of the second liner or tool. In light soil the clack valve is employed which is pivoted to the second liner or tool to lie parallel therewith and will pivot to close the bottom of the second liner or tool to engage a stop lie horizontally when the liner or tool is raised.
In heavy ground a core retainer or core retaining ring or projections are sufficient to form a closure for the second liner to retain the spoil therein. Means are provided to withdraw the second liner or tool from the bore hole and an adjustable pivoted stop on the lower end of the tubular liner to form a closure for the lower end of the second liner or tool in soft soil or sand to hold the clack valve transversely of the tube to lift the spoil during removal of the second liner or tool from the borehole.
The invention will be described with reference to the accompanying drawings: Fig. 1 is a vertical section of a bore hole with a liner therein Fig. 2 is a similar section showing the second liner in the bore hole with a vibrator mounted thereon Fig. 3 is a similar section showing the second liner partially withdrawn from the bore hole Fig. 4 is a similar section showing reinforcement in the bore hole Fig. 5 is a similar view showing the bore filled with concrete and the first liner substantially withdrawn from the bore.
Fig. 6 is an enlarged detail section of the lower end of the second liner showing the valve closed Fig. 7 is a section on line 7-7 fig. 6 Fig. 8 is a detailed view of the stop of the valve The method is fully applicable over a limited range of soil types, i.e. those of a sandy nature, soft silts, peats etc. which do not contain rocky formations or larger boulders. A steel tube is driven into the ground by a vibrator2 in known manner two the required depth of the pile from 10 to 60-70 feet as shown in fig. 1 to form a liner 1 for the bore.
A second liner tube 3 of smaller diameter than the tubular liner 1 is driven into the bore by the vibrator 2 concentrically with the liner 1.
The second liner 3, when used in light soil or sand is formed at its lower end with a clack valve 4 as shown in figs. 6 and 7, pivoted on a hinge rod 5 welded at each end across an are of the liner3 and forming a hinge adapted on the insertion of the liner 3 into the bore hole to pivot the valve into the dotted position 6to allow the linerto move downwards.
Alternatively when used in heavy soil or clay a core retainer may be provided at the lower end of the second liner or tool to retain the core when the second liner or tool is withdrawn. The core retainer may be in the form of a ring or series of projections on the inside of the lower edge of the second liner to retain the heavy soil or clay when the liner is lifted. When the liner 3 has reached the bottom of the bore the liner is then withdrawn upwardly by a crane in the normal manner and the core retainer or the clack valve 4 under the weight of the spoil in the bore closes into the position shown in fig. 3 and the chain dotted position 7 in fig. 6, and on further lifting of the liner 3 the spoil in the bore hole is raised therewith.
The clack or flap valve 4 closes onto a stop 8 pivoted in a recess in the liner3 diametrically opposite the hinge 5. The stop is constructed with a frame 9 and a member 10 pivoted on a pin 11 extending through the frame. The frame 9 is welded into a recess in the liner 3 and secured in this position before the liner is inserted into the ground.
The liners are inserted into the ground in known manner by a vibrator which is suspended from a crane and mounted on the upper end of each liner in turn, the vibrator being formed with slotted base plates slidable on the vibrator frame to accommodate liners of differing diameters. Afterthe insertion of the liner3 the clack or flap valve4 falls onto the stop 8 as the liner is lifted out of the bore and lifts the spoil therefrom.
When the liner3 has been removed concrete 13 is poured into the bore and reinforcing cages 12 or rods may be lowered into the bore before the concrete as shown in fig. 4 and the liner 1 is then withdrawn as shown in Fig. 5.

A method of pile driving comprising driving a first tubular metal liner into the ground by a vibrator and driving a second concentric liner or tool inside the first liner, the second liner or tool having a core retainer at its lower end, means for withdrawing the second liner or tool from the bore hole with the core retainer to cause the spoil to be lifted with the second liner from the bore hole and allowing the spoil to be discharged from the liner.
