SLIDE RAIL SHORING SYSTEM Primax represents the ultimate shoring design in Slide-Rail Shoring Systems combining practice with ingenious ideas and adept functional principles to provide the most reliable, and user friendly shoring systems in construction industry. In addition to conceptual novelties Primax slide rail shoring systems come with lighter but stronger components for easier manipulation and transportation. A UNIQUE PANEL WHILE USING PARTIAL CONNECTIONS For the first time, partial locking connections apply for both, inner and outer shoring walls minimizing resistive forces during installation and removal while increasing the safety by preventing the of inner wall to kick-in the trench. A unique design applies for both outer and inner shoring walls. Thus, no more headaches which, where or how many s are outer or inner. Very light and user friendly rail posts having a single guide only, are also available for both linear or corner rail posts to be used in relatively shallow applications combining same s and strutting assemblies as regular rail posts (US Pat. 7,309,191). PANELS THAT SWING Shoring s access the rail post at ground level. Each just simply swings into outer guide of rail post. For the inner wall, the merely enters from the front side of the rail into inner guide to slide within. This is valid for both linear and corner rail posts. The guide of the inner shoring wall is half way of the rail post easing the insertion and removal of shoring s respectively into and from the ground. In addition, the weight of the rail post is consequently reduced while its strength is highly concentrated at the cantilever. REMOVABLE CUTTING EDGE By introducing unique design with removable cutting edge, PRIMAX have eliminated the concept of top or base s. Actually, each is a top or base by merely removing or fixing the cutting edge. VERSATILE STRUTTING ASSEMBLY When it comes to the spreaders Primax brings a multitude of solutions and other novelties by introducing articulated strutting assemblies providing a very big pipe culvert even when placed at end position. Equipped with rollers at upper and lower ends, the strutting assemblies are vertically mobile accommodating various pipe culverts without interfering objects underneath. Various strutting assemblies are availabe: rigid and articulated. By using pinned connections for their members, the articulated strutting assembly could take the configuration best adapted for application while providing other unique advantages, such as: - Equal distribution of the load onto the rollers. - Quick expansion of the strutting members.
Introduction of new and strutting assembly sliding between opposite rails is another simplifying technique of making a strut frame. This mono-spreader assembly extremely eases the crossing of two or more of them for applications on pits having big or very big cross section. Adaptable in site condition, these strutting assemblies take advantage of their featured properties when it comes to any particular application by being, in addition, able to access or leave the rail post through either ends. CORNER RAIL POST FOR HEXAGONAL OR OTHER POLYGONAL PITS The novelties of PRIMAX are not limited in the pipeline applications. For pit applications, various combinations are now at your hand. Here is the first corner rail post able to make a polygonal pit having more than four corners. When using a hexagonal and/or octagonal pit, there is no need for long cumbersome spreaders in between rails posts allowing a completely free working space to build any required structure within. Thus, even when using short s it is possible to obtain large and obstacle free cross section for the excavation. As the whole structure is under compressive load lighter s and bigger tolerances in the connections -rail post allow for easier installation and removal of the shoring (US Pat.7,309,191). MULTISTEP FOR CONFINED AREAS A particular limitation of slide-rail systems has been the overhead obstacles such as cables, buildings or other objects in inner-city applications. Although PRIMAX slide rail shoring systems allow to swing the s at ground level, it is impossible however to use long rail post, for deep excavations when being inside a building or having very low overhead obstacles. Now, with PRIMAX it's possible to shore even in these cases by introducing the telescopic concept in the design of the rail posts. Short rail posts slide vertically relative to each other creating thereby two or more shoring walls. This feature notes the supremacy of these systems when retrofitting exiting structures in inner-city applications. In this case, the strutting assembly uses additional members acting simultaneously on the upper and the lower rail posts. Also, other customized designs by PRIMAX allows for using sliding shoring systems in tight and cumbersome circumstances. In addition, the telescopic system allows the use of lighter components resulting on easier installation and removal of shoring. These components are compatible with other shoring systems creating a versatility of choice and applications (see below).
SLIDING SHORING SYSTEM WITHOUT RAILS Primax comes to present a very new sliding shoring system designed to be used in shallow excavations up to16 ft deep. Ideal for inner city applications, this sliding shoring system discards heavy and cumbersome rail posts; it uses only large shoring s and special strutting assemblies. The strutting assembly has a pair of short vertical members provided on either side with guides for sliding shoring s. The shoring s are arranged in pairs against opposite walls of the trench, and held vertically by adjacent strutting assemblies spaced apart lengthwise. Each strutting assembly has at least one horizontal strut fastened in between the pair of vertical members. If needed, the horizontal strut is hydraulically activated to exert pressure on either shoring wall. Like the slide rail shoring, the Sliding Strut Shoring is a dig and push system. Assembled before or after excavating two or more feet of trench, the system is lowered down as excavation progresses. What makes this shoring system more useful, and economically very efficient, is the fact that it uses the same shoring s as Slide Rail Shoring System. Also, lighter, single wall shoring s ranging from 4 ft. to 1 ft. tall are available upon users request. Depending on the application, the vertical members of strutting assembly, when needed, are provided with rollers to ease sliding of shoring s (US Patent 7,056,068). TRENCH SHIELD WITH SLIDING SPREADER A trench shield provided with strutting assemblies allowing to adjust the spreaders at any level of the shoring walls means adjustable pipe clearance, it means no more cumbersome arches for big pipes and box culverts, or in boring pits. Also, it means assembling and lowering the trench shield within excavation while keeping the shoring walls aplomb. Primax introduces a trench shield that works both ways, as a sliding shore, dig and push, and as standard trench shield, pull inside the trench. Each shoring slide interlockingly withing the guides of a adjacent strutting assemblies. Similarly to a slide rail shoring system, the s slide independently downward when digging within the shield. When required, the strutting assembly is hydraulically activated, to pressure the wall of the excavation. The spreaders are secured at various heights of the shoring walls by special pins. Furthermore, special s designed to have reverse cutting edges at their top and bottom allow them to be used all ways, upside down, inside out, while their staking is extremely facilitated. However, the guides of the strutting assembly are compatibly designed to the s of slide rail shoring to allow these lasts to be used as trench shields as well. (US Patent 7,056,067).
