DMITRY NIGOLAJEWITSCH ALEXEEFF, OF MOSCON, RUSSIA.
PROCESS FOR MAKING AND PLACING CONCRETE PILES.
Specification of Letters Patent.
Patented @st. 31, 1916.
Application filed August 29, 1912. Serial No. 717,749.
To all whom it may concern:
Be it known that I, DMITRY NICOLAJE- wrrsorr ALEXEEFF, a subject of the Emperor of Russia, residing at No. 14: Krasnoprudnaja street, Moscow, in the Government of Moscow, Russia, have invented a new and useful Improved Process for Making and Placing Concrete Piles, of which the fol lowing is a specification.
This invention relates to a process for the construction of concrete piles by driving in a driving pile which draws with it a protective tube. According to this invention, after the withdrawal of the driving pile there is inserted in the protective tube in combination with its reinforced edge, a di recting tube, into which the concrete is rammed while the protective tube together with the directing tube are gradually withdrawn. This process has in comparison with those already known the considerable ad vantage that one and the same protective tube can be used for the production of any number of concrete piles, because it does not remain in the earth. The use of the inner directing tube has moreover the ad vantage that in consequence of the interspace between the directing and the pr0tecti ve tube when the concrete is rammed in the directing tube begins to shake and the friction of the concrete on the inner surface of the tube and consequently the work of ra1nming it down is diminished.
In the accompanying drawing is illustrated a construction for carrying the invention into effect.
Figure 1 is a longitudinal section through the protective tube with the driving pile inserted. Fig. 2 shows in front view the directing tube to be inserted in the protective tube after the withdrawal of the driving pile. Fig. 3 shows the collar serving for the withdrawal of the protective tube, and Fig. 4 the block which serves for ramming. Fig. 5 shows a longitudinal section through the protective tube with the directing tube inserted.
This process for the construction of concrete piles is adapted for any soil which permits of the ramming of piles. The proc ess consists essentially in placing a wood or metal pile'A (Fig. 1) provided below with a metal shoe which has a heel-piece C inslde a protective tube, in the lower part whereof there is secured an annular inseu tion which is so formed that the heel C of the shoe B presses against it. There-upon the pile A is driven into the ground by means of an ordinary pile driver, and carries the protective tube D with it. When the resistance of the ground is suliicient the pile A is drawn out of the tube 1) and into the latter there is inserted a directing tube F (Figs. 2 and 5) the internal diameter of which is equal to the opening in the part E (Fig. 1). The lower part of the tube F has a reinforcement C, by means of which the tube presses upon the part E (Figs. 1 and There is moreover at the upper part of the protective tube A a clamping device (shown in front view in Fig. 3) by aid of which the protective tube can be gradually withdrawn out of the end of the other tube by means of a windlass or the like. Simultaneously, with the removal of the protective tube A concrete is poured in the directing tube F and is firmly rammed with a rammer K (Fig. 4) which possesses a somewhat similar diameter to that of the direct ing tube and is fastened to a cable which passes over a pulley suspended above the tube.
The process is continued until the protective tube is entirely withdrawn and the hole is left full of concrete.
What I claim is:
1. A process of pile driving and excavating consisting in driving a pile surrounded by a protecting tube, drawn by said driving pile, drawing said pile, inserting a filling tube of thinner material and smaller in external diameter than the internal diameter of said protecting tube inside the latter so as to be placed out of contact with the pro tecting tube, placing concrete .in small quan tities into said filling tube and ramming said concrete so as to set said filling tube into vibration with simultaneous raising of tubes until they are entirely taken out of the ground and the space thus left is filled with concrete.
2. A process of pile driving and excavating, consisting in driving a pile surrounded by a protecting tube, withdrawing said.
clar on,
pile, inserting a filling tube of thin material In testimony whereof I have signed my and smaller 1n external diameter than the name to this speclficatlon in the presence of In lnternal dlameter of sald protectlng tube 1ntwo 'subscrlblng wltnesses.
side the latter, so as to be spaced out of v contact with the protecting tube, filling in DMITRY NICOLAJEWITSOH ALEXEEFF' concrete into said filling tube and ramming Witnesses: said concrete so as to set said filling tube L. R6LL, into Vibration. CHR. ENFURT.
