DETAILED DESCRIPTION

(18) It is to be understood that the following disclosure provides many different embodiments, or examples, for implementing different features of various embodiments. Specific examples of components and arrangements are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. In addition, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

(19) FIGS. 1 and 2 depict combined wall system 10 consistent with at least one embodiment of the present disclosure. Combined wall system 10 may be constructed from sheet pilings 12 and king piles 100. Sheet pilings 12 and king piles 100 may be formed from a rigid material such as steel. Sheet pilings 12 and king piles 100 may be driven into the ground individually such that adjacent sheet pilings 12 are connected at the sheet interfaces and sheet pilings 12 are connected to an adjacent king piles 100 at king pile interfaces 16.

(20) As shown in FIG. 2, each sheet piling 12 may include interlock connectors 14 positioned at each vertical edge of sheet piling 12. Interlock connectors 14 are designed such that adjacent sheet pilings 12 may be coupled together at the sheet interface by interlocking interlock connector 14 of a first sheet piling 12 to interlock connector 14 of a second sheet piling 12.

(21) Each king pile 100 may include king pile interlocks 107a, 107b, discussed further herein below. King pile interlocks 107a, 107b are designed such that a sheet piling 12 may couple to king pile 100 at each king pile interface 16 using interlock connectors 14 respectively.

(22) In some embodiments, interlock connectors 14 and king pile interlocks 107a, 107b may be, for example and without limitation, male and female Larssen interlocks, ball and socket interlocks, or finger and jaw interlocks.

(23) In some embodiments, as depicted in FIGS. 3-5, each king pile 100 may be formed from first flange 101, second flange 103, and web 105 to form an “H” shaped beam. First flange 101 may include first flange body 102 having a length l.sub.1, width w.sub.f1, and thickness t.sub.f1. Second flange 103 may include second flange body 104 having a length l.sub.2, width w.sub.f2, and thickness t.sub.f2. First flange body 102, second flange body 104, and web 105 may be generally rectangular plates. In some embodiments, first flange body 102 and second flange body 104 may each include king pile interlocks 107a, 107b formed integrally therewith. In some embodiments, as discussed further below, second flange 103 may be formed without king pile interlocks 107a, 107b. First flange 101, second flange 103, and web 105 may be formed separately as depicted in FIG. 5 and joined together as depicted in FIGS. 3, 4, by, for example and without limitation, longitudinal welds 109. In some embodiments, web 105 may be formed from a rectangular plate of cold or hot-rolled steel.

(24) In some embodiments, as depicted in FIGS. 6, 7, first flange 101 (and second flange 103 where second flange 103 includes king pile interlocks 107a, 107b) may be formed such that king pile interlocks 107a, 107b are integrally formed at edges 111a, 111b, respectively, of first flange 101. For example and without limitation, first flange 101 may be formed by hot-rolling such that king pile interlocks 107a, 107b are formed into first flange body 102 as first flange body 102 is formed during the hot-rolling operation. By forming king pile interlocks 107a, 107b integrally with first flange body 102, additional manufacturing steps including, for example, welding of separate interlock connectors to an H-beam as in traditional king piles may be avoided, providing a stronger, lighter king pile with fewer potential weak-points compared to a traditional king pile.

(25) In some embodiments, first flange 101 may include drop nose 113. Drop nose 113 may be an extension from flange face 115 of first flange body 102 that runs along the length of first flange 101. Drop nose 113 may, for example and without limitation, be used as the point of welding between first flange 101 and web 105 (as depicted by longitudinal welds 109 in FIG. 3). Without being bound to theory, drop nose 113 may, for example and without limitation, increase beam strength of first flange 101 prior to assembly of king pile 100, may increase the strength of longitudinal weld 109 by moving longitudinal weld 109 away from flange face 115 and thereby reducing stress concentration at the joint, and may provide a more convenient geometry for joining first flange 101 to web 105 by longitudinal weld 109.

(26) In some embodiments, first flange 101 and second flange 103 may both include king pile interlocks 107a, 107b. In some such embodiments, as depicted in FIG. 8, double king pile 200 may be formed by interlocking two king piles 100a, 100b using king pile interlocks 107a of both first flange 101a and second flange 103a of king pile 100a to couple to king pile interlocks 107b of first flange 101b and second flange 103b of king pile 100b, respectively. Double king pile 200 may be used to form combined wall system 10′ as depicted in FIG. 9 by coupling sheet pilings 12 to king pile interlock 107b of first flange 101a of king pile 100a and to king pile interlock 107a of first flange 101b of king pile 100b. Double king pile 200 may, for example and without limitation, provide additional structural support to combined wall system 10′ as compared to combined wall system 10′ as described herein above.

(27) Because first flange 101 and second flange 103 are formed separately, first flange 101 and second flange 103 may, in some embodiments, have different configurations. For example, in some embodiments, first flange 101 and second flange 103 may be formed with different dimensions as further discussed below. In some embodiments, as depicted in FIGS. 10, 11, second flange 103′ of king pile 100′ may be formed as a rectangular sheet of cold or hot-rolled steel and may not include king pile interlocks 107a, 107b. In some embodiments, second flange 103′ may include or may omit a drop nose.

(28) In some embodiments, first flange 101, second flange 103, web 105, and sheet pilings 12 may include one or more specification parameters, as outlined in FIG. 12, which may be selected with regard to the desired design specifications of combined wall system 10. For example and without limitation, the thickness of web 105 (web thickness t.sub.w), height of web 105 (web height h.sub.w), thickness of first flange 101 (t.sub.f1), width of first flange 101 (w.sub.f1), thickness of second flange 103 (t.sub.f2) (here depicted as plain second flange 103′), width of second flange 103 (w.sub.f2), type of sheet piling 12, thickness of sheet piling 12 (t.sub.s), and length of sheet piling section (l.sub.s) may be varied by utilizing components having different specification parameters to form king pile 100 and combined wall system 10 having desired properties. In some embodiments, first flange 101 may be selected from a plurality of flanges having different cross-sections and may therefore have different weights and strengths depending on configuration. For example, in some embodiments, first flange 101 may be produced in heavy cross-section 301a, medium cross-section 301b, or light cross-section 301c, depicted in FIGS. 13A-C, respectively. In such an embodiment, light cross-section 301c may use less amount of material than medium cross-section 301b, which may in turn use less material than heavy cross-section 301a despite other design specifications (such as width w.sub.f1) remaining the same. By tailoring the specification parameters of combined wall system 10 to the intended use of combined wall system 10, a combined wall system 10 may be designed that more efficiency uses material than standardized parts, and may therefore, for example and without limitation, reduce unnecessary weight and costs in the procurement, transportation, and handling of the components of combined wall system 10.

(29) For example and without limitation, in some embodiments, web 105 may be provided in thicknesses (t.sub.w) between 0.3125″ and 0.750″ in 0.125″ increments and in heights (h.sub.w) between 20″ and 45″ in 1″ increments. Second flange 103′, where a plain rectangular plate is used, may, for example and without limitation, be provided in one or more thicknesses (t.sub.f2) including, for example and without limitation 0.875″, 1.0″, and 1.1875″.

(30) In some embodiments, configuration tool 400 as depicted in FIG. 14 may be used to determine design specifications for components of combined wall system 10. Configuration tool 400 may be stored on a non-transitory, tangible permanent memory medium that includes computer program instructions for a computer device. In some embodiments, one or more pieces of data about the desired combined wall system 10 and its environment including, for example and without limitation, geomechanical soils data and loading data, may be used as inputs into configuration tool 400. In some embodiments, configuration tool 400 may include multiple input parameters. For example and without limitation, configuration tool 400 may include a pile selection tool with inputs such as single or double-king pile systems, type of sheet piling (ZZ Sheet), moment of inertia, section modulus, and maximum pile section depth. In some embodiments, configuration tool 400 may include a sheet pile wall tool with inputs such as cantilever or anchored style wall, single or double-king pile systems, type of sheet piling, wall height, beam length, beam/sheet ratio, wall length, minimum material grade, section height, active and passive water level, soil density, soil friction angle, safety factor, maximum deflection, and maximum pile section depth. In some embodiments, configuration tool 400 may include a corrosion tool with inputs such as type of sheet piling, corrosion rate, maximum moment, and maximum shear. In some embodiments, configuration tool 400 may include a pile cap cost tool with inputs such as pile cap dimensions, reinforcement ratio, and configured cross section.

(31) As depicted in FIG. 15, once inputs have been entered (401), configuration tool 400 may determine the structural properties required for combined wall system 10 to meet the design requirements (403). Configuration tool 400 may then iteratively run calculations of different combinations of specification parameters for combined wall system 10 (405). The components corresponding to each set of specification parameters are checked for buckling and slenderness regarding height and thickness (407). In some embodiments, this operation may include, for example and without limitation, calculating the slenderness ratios between first flange 101, second flange 103, and web 105 to evaluate the propensity of king pile 100 having specification parameters of each set of specification parameters buckling under the anticipated load. In some embodiments, a minimum slenderness ratio may be specified. Configuration tool 400 may compare each of the components corresponding to each set of specification parameters to determine the most efficient combination of specification parameters that meets the design requirements (409). In some embodiments, configuration tool 400 may select, for example and without limitation, a combination of specification parameters that meets the minimum slenderness ratio for a beam design under the loading parameters that has the minimum thicknesses and heights. Configuration tool 400 may then communicate the determined most efficient combination of specification parameters (411) to the user by, for example and without limitation, a graphical user interface as depicted in FIG. 14.

(32) In some embodiments, as shown in FIG. 16, configuration tool 400 may include output module 500. Output module 500 may, in some embodiments display the most efficient combination of specification parameters. In some embodiments, output module 500 may generate one or more models 501 of a combined wall corresponding to the most efficient specification parameters. In some embodiments, output module 500 may provide a solution of a combined wall using both sheet pilings 12 and king piles 100, shown at 503 including model 505, as discussed herein above and pipe-piling solution 507, including model 509, to meet the required specifications. In some embodiments, output module 500 may include material requirement module 511, which may display the number of king piles 100 and sheet pilings 12 or pipe piles and sheet pilings 12 needed to complete the specified combined wall. In some embodiments, material requirement module 511 may output the overall weight of the materials of the combined wall.
