COMBINED ENERGY DISSIPATION SCAFFOLDING STRUCTURE FOR PREVENTING FALLING ROCK FOR HIGH AND STEEP SLOPE IN SEISMIC REGION
The present invention discloses a combined energy dissipation scaffolding structure for preventing falling rock hazards for high and steep side slope during highway construction, which belongs to the field of prevention and cure against highway disaster and post-disaster reconstruction engineering in earthquake area. The combined energy dissipation scaffolding structure mainly comprises five parts: a top surface impact-resistance system closely jointed with the existing slope surface, a top surface support system composed of 3D stereographic steel frame systems, a scaffolding body structure composed of a cross beam and support steel-pipe posts at both sides, a mountain-side anchorage system for anchoring the top surface impact-resistance system and the scaffolding body structure, and an anchoring-type steel-plate concrete composite foundation, wherein a fixed base is welded with the bottom of the steel-pipe post and is driven in the foundation soils using anchor rods. The combined energy dissipation scaffolding structure not only can prevent potential safety hazards caused by dangerous crag falling rock at high and steep slope in a seismic region to highway construction and vehicle travelling, but can effectively improve the stability and anti-seismic capability of scaffolding structures. Compared with the traditional shed tunnel structure, the combined energy dissipation scaffolding structure has the advantage that the construction time is greatly reduced, thereby being beneficial to making road unblocked and improving anti-disaster capability.
Illuminating safety net
Disclosed is an illuminating safety net which includes a net body which has a quadrilateral perimeter of elongate tensile members, and a plurality of elongate tensile elements attached to the perimeter and extending within the perimeter in at least two transverse directions; and an elongate flexible lighting strip engaged to the net body along at least part of a perimeter edge of the perimeter.
Roadway cable barrier system
A roadway cable barrier includes a post located adjacent to a roadway and extending vertically from a ground level to a top end, a connector having a first leg and a second leg spaced apart and extending in the same downward direction from a top section, the top section is positioned on the top end of the post such that the first leg and the second leg are positioned on opposite sides of the post from one another, a retaining loop is formed by one of the first leg and the second leg and a longitudinally extending roadway barrier cable is disposed within the retaining loop.
SYSTEM AND METHOD FOR MITIGATING ROCKFALLS
A system of the invention includes at least one barrier layer, a plurality of rockfall attenuators, and two primary anchor points to anchor opposite lateral sides of the barrier layer. The attenuators may be secured to an upper portion of the barrier layer. The attenuators create a gap or separation between the surfaces of the slope upon which the barrier layer is installed. The attenuators may be secured to the barrier mesh by a single cable routed through cable eyes formed on each of the attenuators. Opposite ends of the cable are secured to the sloping surface by the two primary anchor points. The attenuators are free floating members in that they are not attached to the sloping surface. The invention further includes attenuators as a sub-combination and a method of installing the system.
