Abstract
A sectional headwall (10) for a drain pipe (72) includes a unitary base member (12), a unitary sectional member (14) positioned on top of the base member (12), and a unitary lid member (16) positioned on top of the sectional member (14). The unitary base member (12) includes two longitudinally extending walls (42,44) and two end walls (46). The base member (12) further includes a sleeve (48) extending between and connecting the longitudinal walls (42,44). The sleeve (48) defines an aperture (50) extending through the longitudinal walls (42,44) for receiving a drain pipe (72). A drain pipe adapter (80) may be inserted into the aperture (50) to accommodate different sized drain pipes (72).
Claims54
A headwall assembly for supporting a drain pipe, comprising:
- a unitary base member having two longitudinal walls and two end walls, the longitudinal walls and end walls defining an opening extending through the base member for receiving filler material into the base member, the base member further including a sleeve ending between and connecting the longitudinal walls, and the sleeve defining an aperture extending through the longitudinal walls;
- an annular drain pipe adapter configured to be received in the sleeve and having an inner diameter sized to receive the drain pipe;
- and
- a unitary lid member configured to engage a top end of the base member and enclose the top end of the base member.
A headwall assembly for supporting a drain pipe, comprising:
- a unitary base member having two longitudinal walls with the longitudinal walls and end walls defining an opening extending through the base member for receiving filler material into the base member with the base member further including a sleeve extending between and connecting the longitudinal walls, with the sleeve defining an aperture extending through the longitudinal walls;
- an annular drain pipe adapter configured to be received in the sleeve and having an inner diameter sized to receive the drain pipe;
- a unitary sectional member configured to engage a top end of the base member, with the sectional member having two longitudinal walls and two end walls defining an opening extending through the sectional member for receiving filler material into the sectional member;
- and
- a unitary lid member configured to engage a top end of the sectional member and enclose the top end of the sectional member.
A method of constructing a headwall, comprising the steps of:
- providing a headwall assembly comprised of a base member and a lid member, with the base member having a ground engaging edge for engaging the ground;
- positioning the base member in engagement with the ground along the ground engaging edge of the base member, with the base member having two longitudinal walls and two end walls defining an opening extending through the base member, and with the base member having a sleeve extending between and connecting the longitudinal walls, with the sleeve defining an aperture extending through the longitudinal walls;
- extending a drain pipe through the aperture defined by the sleeve;
- filling the opening in the base member with filler material;
- and
- positioning the lid member on the base member such that the headwall is formed and a top end of the base member is enclosed.

- a unitary base member having two longitudinal walls and two end walls, the longitudinal walls and end walls defining an opening extending through the base member for receiving filler material into the base member, the base member further including a sleeve ending between and connecting the longitudinal walls, and the sleeve defining an aperture extending through the longitudinal walls;
- and
- a unitary lid member configured to engage a top end of the base member and enclose the top end of the base member,
- wherein one of the lid member and base member comprises a male connecting member configured to cooperate with a female connecting member formed in the other of the lid member and base member to connect the lid member to the base member.
