A security system provides a barrier above a ground level, and includes a first support element extending in a first direction and a second support element extending in a second direction. The security system further has an elongated carrier element extending in a third direction, where the third direction is transverse to the first direction and the second direction. The first support element and the second support element are attached to a lower surface of the elongated carrier element to provide support for the elongated carrier element, where both the first support element and the second support element extend away from the elongated carrier element on opposite sides of the elongated carrier element. The security system further includes a removable stanchion extending upwardly from an upper surface of the elongated carrier element from a point below ground level to a point above ground level.

The invention relates to a connecting device for a pole of the support structure for road equipment, including a hollow drum, having a circular, elliptical, or polygonal section, comprising a first end for anchoring to the foundation, a second end for fixing to a lower end of the pole, and a central part with a wall portion configured for deforming in a controlled manner when an impact force acts on the pole, such that the lower end of the pole is displaced upwards and twisted in the direction of the impact force. A support structure for road equipment including the connecting device is also an object of the invention.

The present invention provides an anchor pile and installation method for the same, which includes insertion hole portions and guide portion formed in the side surface of a hollow pipe. In a state where a resistance member formed of a material that can be elastically deformed is stored within the pipe, the anchor pile is driven into the ground. When an auxiliary tool is used to pull up the resistance member in a vertical direction within the pipe after the anchor pile is driven into the ground, the protrusion portions of the resistance member slide on the guide portions and are deformed so as to be opened and extended toward the insertion hole portions. The protrusion portions of the resistance member are protruded from the insertion hole portions toward the ground and function to provide the resistance force of the anchor pile in the ground.

A method of forming a post sleeve within a post hole in the ground to include a post receiving cavity to insertably receive and support a post is provided. The method includes positioning a post sleeve core within the post hole with the aid of an elongate installation member and depositing uncured material into the post hole to at least partially surround the post sleeve core while the post sleeve core is attached to the elongate installation member. The method further includes allowing the uncured material to harden around the post sleeve core to form at least a portion of the post-receiving cavity of the post sleeve and removing the post sleeve core from the hardened material to expose the post receiving cavity to receive and support the post. Other related methods of forming post sleeves are also provided.

A ground spike with an attachable mounting bracket. The ground spike has an angled tip adapted to be driven into the ground. The top of the spike has a mounting plate configured to be substantially flat with the ground surface when installed. The mounting plate can be of any suitable size or shape. A plurality of slots are located around the perimeter, and extend towards the center for a distance. An upper post fastening section with an open upper end receives and secures a post, such as a mailbox post. Holes in the sides of the fastening section allow for securely fastening the mounting bracket to the post, such as through screws or similar fastening means. The lower end of the post fastening section includes a second mounting plate, or flanges that extend outward at a right angle. The second mounting plate or flanges comprise a plurality of slots that are configured to align with the slots in the mounting plate attached to the spike. Mechanical fasteners, such as bolts and nuts, are used to fasten the mounting bracket to the spike mounting plate. Preferably, the mechanical fasteners are made of a material that breaks when a threshold level of force is applied to the post secured to the mounting bracket.

A safety bollard system for stopping a vehicle. The safety bollard system comprises a pipe, a beam, and one or more pieces of rebar. The pipe has an upper portion and a lower portion, with the lower portion of the pipe being secured in the ground and the upper portion extending from the surface of the ground. The lower portion of the pipe comprises an engagement section and a structure section, with the engagement section being positioned below the structure section. The engagement section can include one or more set of opposing apertures. The beam is housed inside of the pipe and extends from a bottom of the structure section and into the upper portion of the pipe. The one or more pieces of rebar can be inserted through the one or more set of opposing apertures, thereby securing the safety bollard system such that the vehicle stops upon impact.
