L I i l l Application filed September Vmore specially to sheet-pile cores introduced iny levees to prevent seepage through such Y levee, and at the same time `provide'a. flexible core above the topfthereof as Will preyent over-topping of said levee by floods of superstafre extent. i

ne of the objects of the invention-is to provide a cap upon the top of a pile core, said cap having imbedded therein a means for holding a temporary stop-plank mechanism in position. Anotherobject of theinvention is to provide a rcap upon thefupper extremil5 ties `of such an interior pipe-core, saidfcap Aovercoming the inequalitiesin the,height Aliable to .occur in driving such sheet-piling. A further object of the invention" is to provide a means for temporarily holdingV in po- Vsition a forming means used lin connection with the pouring of such a cap'. Anotherv object ofthe invention is to lprovide amea-ns of prevent-ing seepage of Water between such a capv and the super-imposed Vstop-planks.

Still another object of the invention is to provide a holding means whereby said stopplanks are prevented fromv (floating "when rendered buoyant by rising Water. Still other objects of the invention'nwill` appear from the accompanying plans and specifications.

While the accompanying plans and speciication illustrate andV describe the preferred embodiment ,of the invention, they are illus- Vtrative only and are not tobe considered as indicating the only formk and application of the invention nor as excluding other forms Vandapjgicati'ons in which 'the invention can be used.

yF or the protection V'ofvjareas subject to periodic floods, f levees are` constructed of 'earth lAs a `means of strengthening said earthen levees core-wall* is introduced, which acts both as ameans of added strength .i ,i vand also as an impervious layer,:preventing infiltrationwith consequent softening of the levee material and subsequent erosion and Vwashing away. OftentimesV however floods -of-greater or unprecedented heightV rise Ato'or 'above the top of such an .earthen levee and it thereafter becomes useless `as a` flood prevention means. 'As' a temporary andi emergencyexpedienttheheight of-such levees is raised by means of sand bags or -otherqnickly f applied remedies, butsuch eiforts are quite .oftenineffectiveasa complete protection against overtopping of a levee structure by an extremeflood. Y y I e c ,Y V"'*llnsmnvention provi-des anl entirely satisfactory Vmeans for preventing the overtopping of a levee, whether the flood stage be nsual or extreme, with vthe advantage that after'the passing of the flood stage the extraordinary means employed may Ybe -removed, and storedr against a further demand for Yits replacement. At the same time the invention provides a perfectly impervious and indestructible Vcentre core, preventingV the seepage of water through theflevee, land. .likewise the boring of rodents or similar ani-` Y finals therethrough, which latter results in i holes being made in the levee through which structure.

and at the same time make the core imperviousV and remove the objection to,` al pile'structure with a straightjoint therethrough. The

rpiles are driven vin advance of the pouring of C20 the cap. In the driving'of such piles a wash-L pipe is usually employed, such wash-pipe being introduced into the key-,way through a .wash-pipe lgroove at. the top of the. pile and below the headthereof, such provision per- 3,5 mitting Yof the economical and rapidinser- .tion and removal Vof'such wash-pipe, and at :the same time preventing `interference of said wash-pipe' with wthe pipe 'driving hammer.

After` the driving of the pile core, a mass concrete cap even bed for the superimposed stop-planks. e The following means are lprovided to-'make the placing .of this cap rapid and economical, `A dog-hole is cast in the face-.of thepile, said dog-hole'is driven a steel dog, usuallywith a square shank and adapted to engage .and bind with the edgesand interior surfaces of -said hole. .Upon the ydogs is laid -asill adapted' to rest upon the dogs, vand at the saine;115 time that it becomes the bottom form for the superimposed cap itis designed to `engage the side forms required-to retain; kthe saidV cap while it is in a plastic state. yThe said cap is provided and anchor the bottom member of the stopplank assemblage.` This :depression not only cap andthe lowest 'stopeplankm-'emben thereby creating a water tight joint, preventingk seepage, or passage of Water therethrough, w" For the'purpose ofk intimately uniting, the sheet-,pile fcore Aand `-:the superimposedf@ so y IntoV this no i Vwith a delires-C120V sion, in the top thereof ladapted lto receive Y extending throughout the height or'` the said uprights.

cap, holes are cast through said sheet-piles, into which re-inforcing bars are inserted.. The lower ends of these bars are bent normal to the length of these re-iiiforcingbars, and serve to engage the concrete ot' lthe cap so as to unite the pile and the cap together.

An open ended metal box is cast into and with the superimposed cap, said box having a slot on the outer or exposed face thereof box. rIhe slot is wie-e enough to pe shank of a bolt to enter and slide thereY itis so narrow as to prevent the pass g the head attached to said shank. rlhe int-erior area. of the box is slightly larger than the size of the bolt-head. Except for the open upper end and the face slot the box is entirely enclosed. Perforated lugs in the face thereoiiserve to temporarily hold the box in position during the pouring);l oiV the concrete., while back lugs engage with th mass concrete and prevent the displacement of the box after the pouring" of the cap. To position the box accurately a shelf cast upon the back which rests upon the top oi?-` the prescast sheet-pile core. and a ii'unrojects from the back of the box which lits into a slot cast into the head of the sheet-pile. .By means of this iin and slot the boxes are automatically and accurately located on opnosite sides of the sheet-pile core, and the she-li resting upon the heads `ot the piles serves immediately to locate the boxes in a vertical position.

Uprights are provided which are connected to face-plates aga/inst which the stepplanks directly rest. On l*account of the width of the cap, and in order to secure as light weight as isk consistent with strength in the members to be assembled at the time of Hood, spreaders are employed to separate the uprights and Y:tace-plates at their proper distance apart, so that stop-planks can be opposite and staggered Vfaceplates. Uprights, spreaders and face-plates are rigidly connected together by bolts passing through all three members, the heads of said bolts nuts and washers on the outer'face of said The face-plates are vusually or' such length as that when they are in position on the levee their lowerends rest upon the upper surface of the superimposed cam. The i uprights are longer than the face-plates, and their lower ends have bolts therein the heads of which are adapted to enter the hollow inner area of the box while the shank of said bolt passes through the slot in the outer tace of said box. The nut on the outer end of said bolt is adapted to engage, through a washer, with the outer face of said upright, tightening said nut, after the head thereof has entered said box, serving. to rigidly attach said upright with its connected spreader and faceserved against afuture need.V f The stop-planks which are inserted between thereofffor plate tosaid cap and sheet-pile core, they thereby becoming capable of 'sustaining the pressure due to the head of water createdby ythe extreme floodfstag'd'thereby preventing the overtopping of the levee andv its'sheet-pile 70 core7 and preventing inun'dation'.
