SINKING SHAFTS.
SPECIFICATION forming part of Letters Patent No. 543,230, dated July 23,1895.
Application filed December 21 1893. Renewed December 20, 1894. Serial No. 532,506. (No model.)
1'0 all whom it may concern.-
Be itknown that I, JESSE A. DUBBS, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Sinking Shafts, of which improvements the following is a specification.
The invention describedherein relates to certain improvements in sinking caissons for shafts in mining, for bridge-piers, &c.
In some parts of the country mineral deposits are found overlaid by beds of quick sand,'clay, &c., the quicksand being of such character as to render it impossible'to sink a caisson through the same by any of the methods hitherto known in the artsuch, for example, as rendering the quicksand solid by freezing or the injection of hydraulic cement thereinto. It has also been attempted to sink the caisson by providing a circle of piles driven through the clay and quicksand to the bed-rock; but, on account of the depth of the quicksand-i. 6., one hundred and fifty feet,
more or lessthe lower ends of the piles become deflected entirely out of line, especially the lower ends thereof when the inclosed material is removed, as such lower ends are un supported as against lateral movement.
The object of this invention is to provide .for the sinking of a series of hollow piles or casings down through the clay and quioksand to the bed-rock, and then securing the lower ends in proper position. i
In general terms the invention consists in the construction and combination substantially as hereinafter described and claimed. In the accompanying drawings, forming a part of this specification, Figure 1 is a top plan view showing the manner of sinking a caisson according to my invention. Fig. 2 is a sectional elevation of the same, and Figs. 3 and 4 illustrate details as to the construction of the piles or casings.
now passed down through the casings, and
WVhen the quicks and is of such a character as to flow very readily, it is preferred to drive the casings .in contactIwith each other as nearly as possible, so as to form tight'joints as against the ingress of the quicksa'nd into the circle formed by the inclo'sing casings or piles. If desired the casings may be provided on opposite sides with male and female guides at and 5. One of such guides consists of a channel-iron, as shown, and the other guide of a T-iron, both riveted to the casing. These guides will serve to prevent any lateral displacementeither in or out of theseveral piles, and, if desired, the guides may be so constructed as to prevent the shifting of one pile from another during the driving operation. As soon as the circle of piles has been com pleted the clayand quicksand inclosed therebyare removed in any suitable manner, and ashell 6 composed of aseries of sections and having an external diameter approximately equal to the internal diameter inclosing casings or piles, is forced down until the rock is reached. While not necessaryit is generally preferable, to remove the material from the interior of the casing or pile while it is being driven down, so as to permit examination as to thedirection of movement of the pile, whether it is being shifted laterally or not,
lining or shell need not be employed, as the guides will form tight joints as against any materialinflow of the quicksand. Whatever spaces there may be between adjacent piles or casings may be closed by driving piles 7 intermediate of the main piles 1, as shown in Fig. 1. These intermediate piles may be either rectangular or U-shaped in cross-section, as shown. The lower ends of the intermediate piles are made of a chisel shape in order to causethem to hug the main piles closely while being driven in, as shown in the drawings.
I claim herein as myinvention 1. As an improvement in the art of sinking shafts through quicksands, &c., the method herein described, which consists in forcing down and inclosing series of casings or hollow piles to the underlying strata and securing 2. As an improvement in the art of sinking shafts through quicksands, 850., the method hereindescribed, which consists in forcing down an inclosing series of casings or hollow piles to the, underlying strata securing the lower ends of such casings or piles as against lateral movement, and then placing a lining shell within the piles, substantially as set forth.
3. As a means for sinking shafts through quicksands or other mobile material, the combination of a series of casings or hollow piles extending down through the quicksand to the subjacent rock or solid material, and a like series of bars projecting from the lower ends of the casings and into the subjacent material for holding the piles as against lateral movement, substantially as set forth.
4:. Alining for shafts having in combination a series of casings or hollow piles, provided with interlocking guides, and a bar projecting from the lower ends of the casings or piles for holding the piles as against lateral movement, substantially as set forth.
. In testimony whereof, I have hereunto set my hand.
JESSE A. DUBBS.
