Wall structural member and method for constructing a wall structure

A structural member disposed in the ground for use in a wall structure constructed in the ground, wherein a cavity in the ground adjoins said structural member, said structural member comprising:

• a structural beam elongated in a longitudinal direction and having a side, said side facing said cavity, and wherein said cavity extends in a lateral direction substantially orthogonal to said longitudinal direction;
• one or more components attached to said side of said structural beam, wherein said one or more components include any of reinforcing bars and water stops;
• and
• a removable shielding means for temporarily shielding said one or more component from said cavity.

A method for constructing a wall structure in the ground using a first structural member, said first structural member comprising a first structural beam coupled to a removable first shield such that said first structural beam and said first shield define a first chamber, the method including the steps of:

• attaching at least one first component to said first structural beam, said at least one first component disposed in said first chamber;
• inserting said first structural member into the ground;
• excavating a cavity in the ground adjoining said first shield;
• removing said first shield;
• and
• exposing said first chamber to said cavity.

A method of constructing an extended wall structure in the ground comprising:

• inserting a plurality of structural members into the ground, each of said structural members comprising:
• a structural beam;
• a primary shield removably coupled on one side of said structural beam, whereby a primary chamber is formed between said primary shield and said structural beam;
• a secondary shield removably coupled on an opposite side of said structural beam, whereby a secondary chamber is formed between said secondary shield and said structural beam;
• one or more components attached to said structural beam and disposed in any of said primary chamber and said secondary chamber, wherein said one or more components include any of reinforcing bars and water stops;
• excavating a primary cavity between a first primary shield of a first structural member and a second primary shield of a first adjacent structural member;
• removing said first primary shield and said second primary shield;
• exposing to said primary cavity a first primary chamber of said first structural member and a second primary chamber of said first adjacent structural member;
• forming a primary wall in said primary cavity, said primary wall embedding any components disposed in said first primary chamber and any components disposed in said second primary chamber;
• excavating a secondary cavity between a first secondary shield of said first structural member and a second secondary shield of a second adjacent structural member;
• removing said first secondary shield and said second secondary shield;
• exposing to said secondary cavity a first secondary chamber of said first structural member and a second secondary chamber of said second adjacent structural member;
• forming a secondary wall in said secondary cavity, said secondary wall embedding any components disposed in said first secondary chamber and any components disposed in said second secondary chamber;
• and
• wherein said first adjacent structural member, said primary wall, said first structural member, said secondary wall, and said second adjacent structural member are contiguous and form said extended wall structure.
