CONCRETE STRUCTURE.

Application filed December'21, 1923. Serial No. 681,972.

for water to displace the soil in which such members are to be implanted, and also as conduits for concrete in a mobile state to form foundations at the base oit such nienr bers, after they are implaiited; also concrete members adapted tor use in conjunction withk the tubular conduit members aforesaid to form barriers such as may be utilized as bulk heads and similar walls.

My invention includes the various novel features of constructionl and arrangement and method of procedure hereinafter more definitely specified. However, said method ot procedure is the subject matter of my copending divisional application SerialNo. 725,567 tiled July 12, 1924, for Letters Patent of the United States for improvement in methods of sinking concrete structures by means of water jetting. j j In the drawings; Fig. I is a front elevation of a bulk head embodying my improvements, erected in sandy soil, as seen from the right hand side of Fig. II.

Fig. II is a vertical sectional view, taken on the line II, II in Fig. I and in the direction of the arrows on said line.

' Fig. III is a perspective view ot one ot the top slabs shown in Figs. I and II.

Fig. IV is ay perspective view ot one of the lower slabs shown in Figs. I and II.

Fig. V is a diagrammatic view, partly in elevation and partly in section at right angles to the plane ot Fig. II, showing one of the vertical tubular columns ot the struc# ture shown in Figs. I and II, incourse of installation, in accordance with my method.

Fig. VI is a `fragmentary verticalsectional view, ona larger scale than the other figures, showing a joint ina tubular column conduit formador axially alined separable sections. j

Fig. VII is a perspective view of one of the slotted bolts 19 indicated in Figs.V I and II. j

Referring to the` form or my invention Shown in Figs. I and II; a series of vertical tubular columns 1 are installed, in parallel relation, inthe sandy subsoil 2 so as to form a bulk head to protect the top soil 3 from the encroachment or the sea. or other bodyof water 4. Each-ot said columns 1 is a substantially` cylindrical body of concrete, having an axial tubular metal core 6, conveniently formed of an iron or steel pipe screw thread-ed at each end and provided lat its upper end with a screw coupling to engage a pipe or similar size, for the purpose .of effecting the installation of said column',

as hereinafter described.v

Said column has the step 8 formed of concret-e, projecting from but one side thereof, in unita-ry relation therewith, and prei -erably reinforced by the metal member 9 to determine the position andv support the bottom one or the seriesot substantially plane slabs 10 which are each conveniently of the form indicatedin Fig. IV. Each of said slabs 10 comprises a substantially plane rectangular body having a lat face upon its front side and a rib 11 upon its rear side and substantially semicylindrical notches 12 at its respectively opposite ends. Said lower slabs 10 are surmounted by upper slabs 14, each conveniently formed as shown in Fig. III and comprising a substantially plane body with a top flange 15 extending at right angles thereto and overhanging the columns local to said flange and serving to close the openings in the tops of said columns and the cores therein; said body having a plane front face but having its rear tace reinforced by a rib 16 similar to the ribs 11 aforesaid. Said top flange 15 is also preferably reinforced by a similar rib 17, pendent from the under side thereof.`

I find it convenient to detachably connect said columns 1 with said slabs 10 and 14C by providing each ot said columns with a `vertical series of bolts 19 which are imbeddedtherein so as to project at right angles to the axis thereof, as indicated in Fig.k II.

vertically through it at its outer end to receive a wedge 20. Said bolts are adapted to extend between adjoining slabs in the notches y10o Each otsaid bolts has a slot 192L extending the latter secured by driving the wedges 2O into the position shown in Fig. il. lt may be observed that the notches l2 in the ends of the adjoining slabs 10 and le are complementary; so that` each of said bolts 19 suiiices to engage the adjoining ends of two of said slabs and relative displacement thereof is prevented by the single washer 2l and wedge 20 connected with the respective bolt.

As indicated at the left in Fig. l; the columns lv may be installed in the randy soil 2 without any foundation. However, as shown at the right in Fig. l and also in Fig. ll; each of said columns may be provided with a concrete foundation 23 which may be formed after the installation of the column as hereinafter described. Such foundations 23 of course render it more difficult to remove the columns l. Therefore, if the bulk head is designed for temporary use, such foundations are oi'nitted. Of course, the structure assembled as above described and illustrated in Fig. ll may be taken apart by removing said wedges 2O and slabs l0 and 14; and' withdrawing said coluinng, without `impairing any part of the structure which may be used again.

As indicated in Fig. V; the column l may be conveniently sunlr in the soil 2 by connecting with its top coupling 7 the nozzle 25 of the flexible conduit 26 through which wa.- ter 27 may be conveyed to lsaid column and driven downwardly therethrough under pressure while said column is suspended by any convenient overhead tackle. For instance, a cable28 extending from the eye 2S) on said nozzle serves to support said column l in vertically pendent position so that it may be permitted to gravitate into the pit 30 being formed by the water 27 flowing downwardly through the tubular reinforcement 6 of Said column l and thence upward around said column to the surface 3l.

Although l have shown said columns l unitary from end to end thereof; it is to be understood that they may be formed in sec tions as indicated at liL and lb in F Vl.

The construction and arrangementabove described are such that water under pressure may be driven downwardly through the axial tubular conduit 6 of the column l or the column formed of sections la and lb, or any other suitable structural element to sinlr the same into the soil to the desired depth by washing the soil from beneath it and permitting it to gravitate. rfliereafter, the water may be shut off from said nozzle 25 at the valve 50, and the valve 68 be opened to discharge concrete, from the flexible conduit 67,l through said conduit 6 to form a foundation 23 at the bottom thereof.

However, l do not desire to limit myself to the precise details of construction, arrangement and method of procedure herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention, as defined in the appended claims.
