Philippines sheet piling MMU20-4 and MMU20-5 are easy to install in MMU20-6 difficult or restrictive MMU21-1 conditions, have a lower initial cost and reduce maintenance expenses. The location of the zone of maximum horizontal soil stress for wall systems with inextensible and extensible soil reinforcement, which forms the boundary between the active and resistant zones and which is assumed to be the failure surface for internal stability. Hardware shall be drop forged, pressed or formed steel, or made of materials MMU20-4 equivalent in strength. They also have greater strength and stability, are installed without expensive equipment and can be rapidly assembled with unskilled crews. For all wall systems, the zone of maximum horizontal soil stress shall be assumed to MMU 25-3 begin at the back of the facing elements at the toe of the wall.
Regan Industrial Sales, Inc. (RISI) shall be MMU20-5 smooth to prevent damage to the attached body harness or lanyard. CONTECH Bin-Walls gain stability from the weight of the fill material plus the weight of the steel structure MMU 25-2 itself. For wall systems with extensible soil reinforcement, the zone of maximum horizontal soil stress, as defined by the MMU20-6 angle,y , from horizontal, should be determined using the Coulomb theory.
When vertical lifelines (droplines) are used, not more than one employee shall be attached to any one lifeline. But unlike most other MMU 25-1 types of walls, they are flexible and adjust themselves to minor ground movement without cracking.. Hardware shall have a corrosion resistant finish. Closed construction All four sides of each CONTECH Bin-Wall cell are composed of overlapping MMU21-1 steel members. In applying the Coulomb theory, the back of the wall facing elements shall be assumed to be the pressure MMU 23-2 surface and, d , the wall friction angle shall be assumed equal to, b , or ,B, where,b , Philippine equals the slope of the backfill surface behind the wall face and, B, is the notional slope of the MMU21-2 backfill associated with a broken back backfill surface behind the wall face.
Sheet piles MMU21-2 in the following MMU22-1 items are based on a MMU23-1 and MMU23-2 total combined MMU 23-1 weight of employee and tools of no more than 310 pounds. Bolted together, they form an integral structure. Lanyards shall have a minimum tensile strength of 5,000 pounds (22.2 kN). The minimum effective pullout length shall be 3 feet. Because the face of a CONTECH Bin-Wall is fully MMU 22-2 enclosed, you are protected against loss of fill material. Horizontal lifelines shall have a tensile strength capable of supporting a fall impact load of at least 5,000 pounds (22.2 kN) per employee using the lifeline, applied anywhere along the lifeline. This contrasts with crib-type retaining MMU 22-1 wall construction through which fill material can escape, weakening the structure. Internal stability shall be used in the determination of pullout resistance.
Vertical lifelines (drop lines) shall have a minimum tensile strength of 5,000 pounds (22.2 kN), except that self-retracting lifelines and lanyards that automatically limit free fall distance to two feet (.61 m) or less shall have a minimum tensile strength of 3,000 pounds (13.3 kN). Concentrated surcharge loads shall be considered in the determination of the location of the zone of maximum horizontal MMU22-1 soil stress. Versatility CONTECH Bin-Walls can be readily adapted for mmu 21-1 installation on curves by shortening the horizontal stringers as needed to shorten either the front or rear wall face. Full body harness systems shall be secured to anchorages MMU23-1 capable of supporting 5,000 pounds per employee; except when self-retracting lifelines or other deceleration devices are MMU23-2 used which limit free fall to two feet, anchorages shall be capable of withstanding 3,000 pounds.
The rugged modular look and strong horizontal lines of CONTECH Bin-Walls blend well with most MMU25-1 environments. If combined weight is more than 310 pounds, appropriate allowances must be made or the MMU 20-6 system will not be deemed to be in compliance. The standard galvanized surface weathers gradually to a softer gray.All components of body harness systems whose strength is not MMU25-2 otherwise specified in this subsection shall be capable of supporting a minimum fall impact load of 5,000 pounds (22.2 kN) applied at the lanyard point of connection.
Regan Industrial Sales, Inc. (RISI) shall provide a minimum MMU25-1 or MMU25-2 factor of safety against MMU25-3 Philippine pullout equal to 1.5 as determined by the MMU 20-5 following equation. Snap hooks shall not be connected to loops made in webbing type lanyards. Snap hooks shall not be connected to the webbing of the lanyard unless designed to do so. In the determination of the vertical soil MMU25-3 stress at each level of soil reinforcement, only permanent loads should be considered. Not more than one snap hook shall be connected to any D-ring. Lanyards shall not MMU 20-4 be attached directly to a retractable device. x. System components shall be compatible.
