Benefits Of Using Helical Screw Piers-Screw Piles For Pedestrian Bridges

Helical piles cover a diverse range of function when developing heavily-loaded and medium-loaded permanent structures. The final foundations are subjected to extensive tension and compression. Helical screw piles turns up to be an effective solution for multiple design challenges.

The benefits of using this new technique for pedestrian bridges are way more than the traditional construction technologies.

Quick and vibration-free installation– Helical anchors are easy to install even in difficult terrain and sensitive soils. It can be installed with the aid of handheld equipment without drill spoils or soil excavation dumped aside. Installation of screw-piers-screw piles is possible within a limited-access area that too in any weather conditions.

Strength and capacity – Bearing capacity of screw anchors are higher than the conventional piles even if their lengths are identical. The screw piers produce their load capacity from the flat areas of helical plates that are in contact.

Extensive resistance power – Helical anchors are extremely resistant to frost heave and are feasible for a wide range of soil conditions. Its effective in-ground strength in earthquake zones is the most significant advantage among the others. Screw piers remain unaffected by the groundwater and caving soils.

Huge protection against corrosion – The materials of screw piles is typically galvanized to expand its lifespan in aggressive environments. Special coatings on the helical anchors can also be provided if circumstances require extensive corrosion resistance.

Noiseless erection – Installation of helical piles produce much less noise than that of the driven piles. These improvised screw piles also minimize the ground vibration during its erection. Helical pile foundations are extremely environment friendly than the other deep foundations.

Cost effective foundations – Helical Pile constructions can be done in a lower initial outlay. These foundations are possible to relocate and reuse later and are more sustainable that makes the project cost effective.

3 Safety Measures To Prevent Accidents At Pile Driving Site

Source:

Pile Operations initiate soon after the conclusion of pre-construction planning.  The commencement of the tasks trigger a hazardous situation and a concerning time for the pile contractors. The potential of accident associated with pile driving elevates the significance of maintaining safety gears throughout the job. A contractor needs to focus on workers, support, equipment, site condition, materials and every other factor to conduct the project smoothly.

Concentrate on the first step  

The initial stage of pile driving needs more emphasis to ensure a high-quality finishing.  At the onset of a project, the superintendent needs to convey the safety rules to all the employees through a formal meeting. It is even better if printed hard copies are distributed among the workers.

On this meeting, the superintendent must collect the contact numbers of those to be telephoned in emergencies. He even needs to arrange for fulsomely stocked first-aid kits and a trained first aider. A thorough check on nearby hospital and ambulance service is another significant point to focus on.

A review of the operating plan, equipment, availability of on-field safety gears, and safety placards on rigs by the superintendent is essential before starting off the project.

Ensure at most security for the workers

Contractors of pile driving  provide all the vital gears for the laborers. All the operators must be supplied with the listed items to safeguard them while piling.

• BRIMLESS HARD PLASTIC HATS FOR ALL THE WORKERS

• COVER WIELDING GOGGLES WITH 3-4 TINTED LENSES AND EYECUPS FOR THE BURNERS AND CUTTERS

• CHIPPING SAFETY GLASSES WITH CLEAR LENSES FOR THOSE WHO ARE APPOINTED AT CHIPPING AND GRINDING

• WELDING HELMETS FOR WELDERS WITH SHADE 10-12 LENSES. PORTABLE SHIELDS AND SHADE 2 GLASSES WITH SIDE SHIELDS MUST BE PROVIDED IN CASE OF EXTENSIVE WELDING

• NEOPRENE-COATED CANVAS GLOVES FOR WORKERS WHO DEALS WITH CREOSOTED PILES, PLASTIC SLATE AND CEMENT

• LIFE JACKETS AND EMERGENCY BOATS FOR WORKERS HANDLING MARINE OPERATIONS

• A 6# MULTIPURPOSE TYPE 2A-10BC DRY CHEMICAL EXTINGUISHER AT THE ONSITE OFFICE, CHANGE AREA OR TOOL HOUSE

• 2# TYPE 5BC DRY CHEMICAL EXTINGUISHERS ON EACH CRANE AND MAJOR EQUIPMENT

Maintain safety at the site

Onsite projects need much more wariness to avoid any sort of menace. The work area as well as the walkways must be kept free of debris, scrap lumbers, pile cut-offs and other loose materials. A secure handrail and a toe board must be setup for walkways and platforms four feet above the ground or located in a perilous location.

The contractors must supply proper containers for trash, oil rags and other combustible materials. Special precautions are required for pile drivers working in potentially combustible environments.

The pile driving contract for your site concludes harmlessly only if the safety measures are passionately maintained in mutual cooperation of the contractor and the laborers.
