(Cl. 61-59) This invention relates to concrete sheet piling each end at d to enter recesses in the opposite and like structures for the formation of water tight walls and collier-dams and for the carrying of superstructures, andhas for its object to pro 5 vide for the effective connection of adjacent piles to one another without imposing upon the con crete of the piles excessive tension and shearing stresses such aswill arise during the pile driving operation and which may cause fracture thereof. l0 The invention comprises the interlocking or connection together of adjacent piles during and if desired after the pile Vdriving or sinking opera tion by an intermediate part secured to the two adjacent piles by metal tension members passing 15 throughl the concrete of the said piles at intervals in their length, the said members permitting of longitudinal movement of the intermediate in terlocking part relatively to the piles but prevent ing such movement laterally with> relation to the 20 piles. The invention further comprises the improved methods of and means for interlocking piles as hereinafter described> and claimed. Referringto the accompanying sheet of explana Y Figures 1-6 are plan views illustrating nine con structions of sheet pile interlocking means ar ranged in accordance with this invention. ` ' Figure 7 _is a detail View `drawn toan enlarged 30 scale of the end of one of the tension members shown in Figures 4 ,and 7. Figure a is a plan view illustrating the applica tion of the invention to the interconnection ofV substantial"*structures >in the form of caissons which resemble piles except in respect of their dimensions. l v , , Figures 9 and 10 are an elevation and a perspec tive View of complete interconnected piles. '40 In all the figures tension members extend into and through the concrete` at intervals in the verti cal length of keach pileor caisson as shown in Figure 9.v v The tension members project from opposite 45 sidesoi each pile or caisson and the projecting ' parts. .arev shaped or arranged so that they can take an effective hold upon an intermediate member which is to hold adjacent piles >or caissons together while permitting relative longitudinal 50 movement between the piles and intermediate members for the purpose hereinafter more fully speciñed. - . - In Figures 3I 4, 5 and 6, the tension bars are in pairs and may be interconnected by a stirrup piece (as shown at e in Figures 4, 5 and .'7) ad jacent to their ends to hold the bars at the requisite distance apart. The ends f of the pairs of tension barsa2 are turned inwards so that they can take over the sides of the intermediate mem bers c2, c3. The piles are shown at bz'in Figures 10 3, 4, and 5, at b3 in Figure 6. In Figure 8, each tension bar a3 is divided at its ends and the two parts spread apart and their ends f’ turned inwards to embrace the sides of the intermediate members c2. In this figure, the tension bars of the corner pile or caisson g do not extend completely through the caisson but terminate therein with a cross or anchor piece (L13 at the end. The remaining piles are in this figure indicated by the reference b5. ’ 25 tory drawingst- sides of the intermediate member c or c’. 1 . In'Figures 1 and 2, the tension members consist of rods or bars a extending completely through 55 the'concrete'of the pile b or b’ and headed at 20 In all the constructions, each intermediate member extends the whole length of the piles as shown in Figure 10 or any desired portion of such length and serves to bind adjacent piles together so that they cannot separate but it does not pre 25 vent free'relative longitudinal movements of the piles at its opposite sides. ` In driving piles, each pile as it is driven into place has its tension members engaging suc cessivelyvthe intermediate or interlocking mem 30 ber of the pile already driven and it carries down with it the intermediate member at its opposite side. If desired the driving blows may be ap plied to the intermediate member through a part which may permit a limited amount of relative 35 longitudinal movement between pile and inter mediate member. Thus in Figure 10, as the end pile k was driven, its tension members would suc cessively engage in the recess in the intermediate member c2 which had `been driven into the ground 40 with the pile m, and the intermediate member c12 would be driven along with k so as to be ready for engagement bythe tension members of the next pile. In some cases, the intermediate member of the pile which has already been driven, may be 45 locked against endwise movement to its pile to prevent longitudinal displacement when the next pile is being driven. Thev tension rods are sub jected chieñy to tensile stresses, the shearing or twisting stresses being insuii‘icient to cause frac 50 ture of the concrete. Y 'I‘he intermediate or interlocking members in all the constructions may be left permanently in position, or they may be withdrawn after the several piles have been ñnally driven into place 55 2 2,089,763 and the space between adjacent piles ñlled in ample, be of the shapes shown in Figures l and with concrete which keys itself into and around 2) which grip the intermediate or interlocking members may be secured to each pile at its oppo the ends of the tension members as shown in the lower portion of Figures 1-4, , The preferred way of con'creting the. spaces where the intermediate or interlocking members are located will be understood by reference more site sides by bolt like members passing freely through transverse holes through the piles. The present invention obviates the` known de fects of the interlocking means usually employed particularly to Figures 2 and 4. In these it will<> yorfwhich have been proposed for sheet piling and be seen that the intermediate or interlocking prevents damage to the concrete by the inter 10 members c’ or c3 have a central hole n or n’ formed longitudinally therethrough from'end to end.
