A readily replaceable accessible pedestrian signal station is described including a bottom base plate and a sacrificial base plate.

Disclosed herein is a bollard system including an impact receiving post and a foundation cage. The impact receiving post includes an outer surface, a proximal end, and a distal end. The foundation cage defines a three-dimensional lattice structure. The foundation cage is coupled to the proximal end of the impact receiving post and is configured for installation in concrete beneath a ground surface. The foundation cage defines a recess to receive a proximal portion of the impact receiving post. The foundation cage includes a horizontal stop member at least partially extending across the recess and supporting the impact receiving post and preventing the impact receiving post from extending further into the foundation cage before the concrete sets.

A ground anchor having a head and anchoring elements in the form of pipes or rods, wherein the ground anchor comprises an anchor head (5) which has a polygon or an ellipse cross-section, the upper part of which is open or closed with at least one opening having a head socket (7), said ground anchor contains at least two anchoring elements (6) in the form of pipes or rods passing through at least two at an angle to the vertical axis of the anchor head and anchoring element guides fixed to the anchor head (3) wherein the anchoring element guides have a hole or holes (4) for blocking the anchoring element through, wherein a screw or screws (8) lock the anchoring element passes and wherein the head socket (7) has a hole or holes (9) for locking the fastening element (1) with self-tapping screws (2).

An anchor foundation mechanism includes: a vertical cylindrical tubular body formed to be inserted into the ground and having a receiving space therein; a cover part fixed to the bottom of the body by bolts and configured to be easily inserted into the ground; a support integrally formed with the top of the body and having a plurality of through-holes and an installation fixing bolt flange so as to allow the support to be fixed to a facility post after being exposed on the ground; and an anchor assembly formed in the receiving space of the body and having anchor pins for driving the body deeply into the ground and then tightly fixing the body so as to support a load and prevent rotation, and prevent forced pulling out.

In a preferred embodiment of the invention there is a post comprising a plurality of poles 5 located in and extending from a ground surface adjacent to one another. A sleeve 1 is arranged around the poles 5 so that the sleeve and poles combine to provide a shaft. In this embodiment each pole has a tapered ground-engaging end 6 and the sleeve has a large compartment 2 for two of the poles 5 and a small compartment 3 for one of the poles.

A structure of a sign pole is provided. The sign pole includes a tubular member that has a predetermined outer diameter, a predetermined inner diameter, and a predetermined thickness. In a state in which the sign pole is embedded in a ground, the sign pole includes a reinforcement portion having a thickness different from the predetermined thickness while maintaining the predetermined outer diameter in a first range from a first position equal to or lower than a level of a ground surface to a second position located a predetermined distance above the level of the ground surface. The reinforcement portion has a thickness larger than the predetermined thickness.

A barrier apparatus includes a barrier post mounted to a base and extending upwardly from the base. A brace of the barrier apparatus is configured to restrict relative movement between the barrier post and the base. The brace can be mounted to the base so that it extends upwardly and obliquely toward the barrier post. The brace can include block. A reinforcing tube can extend around the block. A mated connection to the front of the brace can include a first mating protrusion extending into a first mating hole, and a mated connection to the bottom of the brace can include a second mating protrusion extending into a second mating hole. The brace or another brace can extend into a rear corner positioned between the barrier post and the base.

A bollard assembly includes a bottom plate with a forward edge and an aft edge, an elongated member mounted on the bottom plate and extending from a forward end to an aft end in a direction from the forward edge toward the aft edge, a bollard secured to the bottom plate with a bollard section of the elongated member disposed inside of the bollard, bars mounted on the bottom plate on opposite sides of the elongated member, and a top plate having a smaller perimeter than the bottom plate mounted on the elongated member and the bars with the bollard extending above the top plate.

A post foundation system is provided. The system has a shaft with a helical disk attached to one end and a post support attached to the other end. The helical disk drives the shaft into the ground as a rotational force is applied to the shaft. A fin section is rotatably coupled about the shaft between its first and second ends. The fin section can have one or more fins extending outwardly from the shaft. The fin section engages the ground to stabilize the post foundation system as the shaft of the post foundation system is driven into the ground.
