This invention pertains to sea walls of con-v the' heads of the batter piles. This beam prevents relative movement of the sheet piles longitudinally of the wall, thus permitting the formation of permanent water-tightjoints between the sheets by simply pouring grout into spaces .provided for that purpose in the contacting edges of the piles. Suitable expansion joints are providedat intervals in the wall.
An object of the invention is the formation of a sea Wall of precast members locked together to prevent leakagethrough the wall.
Another object is the formation of asea wall of precast members locked together by a castin-place beam, the lower part of the wall extendingfar below theunderlying earth thereby preventing passage of water underneath the wall,
and. the upper part of the wall extending in cantilever form above the beam.
Another object is the formation of a permanent wall requiring the minimum of material and providing the maximum of strength and rigidity where wave and water pressure is greatest.
Another object of the invention is the formation of a sea wall having precast vertical members and a cast-in-place horizontal beam so intimately interconnected with the vertical members .that the material in the vertical members may be used in calculating the strength andstiffness of the beam.
Further and other objects and advantages will be apparent from the specification and claims, and from the accompanying drawings which illustrate what are now considered preferred embodiments of the invention.

Fig. 11 is similar to Fig. 10 except that the lowerportions are of :sheet steel. 20

The wall as illustrated in Figs. 1 to 4 inclusive 2 comprises. aseries of reinforced concrete sheet piles--2il in contact with each other and driven at an angle, with their lower ends in the impervious stratum 22, well below any water bearing. sand or soil 24. The normal waterlevel is at 26 and the estimated ultimate water lever is -at28.
The sheet piles. are integral with longitudinal beam 3i], and are braced by batter piles 32, the 35 heads of which are embedded in beam 30 so that they alsoform an integral part of the structure. The-batter piles may be .of any suitable design, a composite type being shown, having a wooden lower section 34. The sheet piles andbracing piles are precast. Theyare driven to-position and then beam 30 is cast in place to complete the structure.
The sheet piles, as shown (Fig. 4), have their edges so shaped as to engage each other as at surfaces 36, 38, to preserve their alignment and to provide spaces to be filled with grout 40 to prevent all leakage through the wall.
"The rear sides of sheet piles 20, Where beam 3llis to be cast, are notched or recessed as at 42 to receive some of the concrete of'the beam :andto expose-some of the vertical reinforcing bars 44 of the sheet piles, permitting reinforcing bars--46 ofthe beamsto loop around bars-44,.thus
binding the beam and sheet piles into an integral mass. This feature results in a great saving of material in the structure, because in calculating the strength of the beam the compression of the concrete of the piles directly opposite the beam may be included, thereby greatly reducing the necessary thickness of the beam. In calculations for compression the cross-section of the beam may be considered as bounded by the broken lines surrounding the beam and part of the pile (Fi 2).
At intervals the structure is provided with expansion joints, one form being shown in Fig. 4, in which one of the regular sheet piles 20 is replaced by a two-piece pile having the same overall shape and dimensions as the other piles and having an expansion joint between its two parts. The two parts forming the expansion pile are designated 48 and 58. The parts partially overlap each other and would partially abut each other were it not for the fact that the abutting surfaces are separated by layers of expansible material 52 and 54 which may be asphaltum or something similar. The overlapped slip-joint surfaces are recessed to provide a vertical cavity in the pile which is filled with expansible material 56. Beam has a joint aligned with joint 52 and filled with similar material 58.
A modified form of expansion joint is shown in Fig. 5, the two parts of the sheet pile being 60 and 62, and the joint being otherwise similar to that shown in Fig. 4 except that the overlapping portions of the pile are separated by expansible material 64, and a sheet of metal having a U-fold 66 is embedded in the overlapping portions of the pile with fold 66 in the asphaltum. This metallic member provides extra security against leakage when the pile sections move relatively to each other.
Fig. 6 shows still another form of expansion joint in which no special two-part sheet pile is used. This joint is formed between two of the regular piles by simply keeping their normally abutting edges out of contact and filling the space thus provided with asphaltum 68.
. Fig. '7 shows an embodiment of the invention in which an unusually high wall is required.
This requirement is met by simply letting the sheet piles project to the proper height and providing an extra longitudinal beam 10 and bracing piles 12 above the regular beams.
Fig. 8 shows an embodiment in which the regular structure is surmounted by .an apron 14 which, at intervals of its length, has webs l6 resting on piles 18,
Fig. 9 shows still another embodiment having a superimposed apron 88 resting on the earth fill 82 behind the wall.
It is sometimes desirable, for reasons such as economy, to use composite sheet piles having their upper portions of concrete substantially as described, and their lower portions, below water level, of wood, sheet metal or other material. Such a structure with lower part of wood is shown in Figs. 10 and 12. The upper pile 82 is of concrete, while the lower part is of wooden planks 84, with their upper ends precast into the lower ends of piles 82, the joints in the planking coming in the spaces between the edges of the concrete piles in the grout filling 40. Of course the joints in the planning are of water-tight design such as the tongue and groove shown in Fig. 11.
In Figs. 11 and 13 the wooden planks are replaced by corrugated sheets of metal 86 having their edges overlapping in grout 68, the overlap extending to the bottom of the pile to prevent leakage.
Under certain conditions, for instance where the upper end of the brace pile is not opposite the center of pressure, it is advantageous to fit the head of the brace pile into a cushioned socket in the longitudinal beam, as shown in Fig. 3 instead of casting the beam and bracing pile integral, as in Figs. 1 and 2-. A layer 86 of asphaltum or other resilient material lines the socket in the beam to provide a flexible joint between beam and pile, thus reducing fiexure strains in the brace pile. Reinforcing rods 88 extend from the center of the brace pile into the beam to prevent their separation if tension stresses should occur, tending to pull the head of the pile from the socket.
It is to be understood that the invention is not limited to the specific construction herein illustrated and described but may be embodied in other forms without departure from its spirit as defined by the appended claims.
