Why Use Concrete Pump?
How do you determine the correct concrete pumping for your project? What makes this concrete positioning technique more effective than dumping from a prepared mixing truck, bucketing with a crane or just using a wheelbarrow?
Concrete pumping helps both now and in the future to reap rewards. Contractors report high customer satisfaction levels and increased opportunities for more projects. Distinct benefits that can have a positive effect on the bottom line of a project include time and labor savings, increased revenues, improved scheduling, decreased site preparation, employee satisfaction, increased quality control, and versatility of concrete placement.
The equipment which is pumping concrete
For pumping concrete, a range of machinery may be used, including truck-mounted concrete pumps, placement booms, high-pressure / high-output trailer pumps, trailer-mounted concrete pumps, and mortar machines. Consider the following when equipping a work site with any concrete placement machinery:
- Job location
- Job size
- Job complexity
- Safety
- Maximum distance
- Maximum height
- Volume of concrete to place
- Concrete mix design, slump, aggregate, and admixtures
- Site restrictions
- Site congestion
- Reliability
Save Time, Save Money, Increase Profits
A concrete pump quicker and more precisely places concrete with less work than any other technique. A work that would take two and a half hours for five people to pour would take just one hour for three people to pump. Compared to truck dumping, contractors that pump concrete regularly report 50 percent labor savings.
Concrete pumping on site allows valuable staff to be reallocated to other tasks. Moreover, a pump can be used to discharge more ready mix trucks in less time, which means completing more jobs in a day.
Gordy's Concrete Pumping Service (Gordy's) was able to create a great platform for their company with a full line of Putzmeister boom pumps, run more efficiently for their customers and also reduce labor costs for their customers. This was especially crucial when, as of January 2007, putting the biggest quantity of concrete consumed on a Midwest site.
Site Specs:
- 130,000 cubic yards of concrete pumped and placed by boom pumps
- 11 different concrete mixes available per specification
- Maneuverability and quick setup of the boom pumps allowed Gordy's to keep the project moving as efficiently as possible
- The 63Z-Meter boom pump used on site is extensive — 203 feet 9 inches vertically and 190 feet 7 inches horizontally
- Pumping Keeps Jobs Moving
Scheduling is one of a concrete pour's most critical aspects. On a busy work site, there is no space for downtime. Contractors with the right equipment efficiently place concrete, irrespective of weather, daytime or working conditions. Positioning and maneuvering equipment around a site can also be critical factors in determining the best concrete method of placement.
"For this project, there has been a whole year of planning and coordination between Webcor and JLS," says Vern Lee, Webcor's construction manager. "Because of Hollywood & Vine's massive footprint and opening date in the fall of 2009, it was a must have everything planned for a ' T. '
"In planning the three pumping stations and the impressive 1,110 meter (3,640 feet) below-grade delivery line system, every detail was scrutinized," says Willie Clemison of JLS. "The placement system includes both horizontal and vertical piping. Webcor and JLS had to ensure that the delivery system could transport concrete without any problem to any of the six placement booms and also allow three placement booms to place concrete at the same time." Putzmeister BSA 14000 was used to reliably pump the long distances required by this project.
Site Specs:
- Curb-to-curb 4.6-acre footprint
- Pumping and placing three different concrete mixes at any given time with six placing booms
- 4,000- to 8,000-psi concrete mixes
- 108,000 cubic yards of concrete
- Placing booms on site have a horizontal reach of 115 feet 3 inches and vertical reach of 122 feet 8 inches
- Six placing booms, pin towers and pumps
- By providing more predictable unloading times, concrete pumps help mixer dispatchers. Due to the absence of interruptions and delays, the steady flow from the pump can also boost finisher productivity.
- Unlike human resources, without complaint, pumps appear on time for work and never take a break for lunch. Backup systems can keep a pump operating through work completion in case of a issue, and wear sections are intended to be easily replaced.
- Site preparation can be time-consuming, labor-intensive and unpredictable, hampering effective scheduling.
Productivity of employees and safety
Not only does concrete pumping make a concrete pour more convenient and consistent, it also improves safety at work. Ready mixing trucks are kept at the curb, away from embankments, excavations and other dangerous obstacles, so that concrete can be placed exactly where it is needed.
Moreover, a concrete pump decreases workplace congestion better than most other techniques, enhancing work effectiveness and safety. Less dangers and a more ergonomic process are advantages that can lead in less sick days and a smoother running company for on-site staff.
A Quality Job Time After Time
Labor and time savings mean nothing if the quality of concrete placement does not meet expectations. For years, contractors pumping concrete have produced superior quality while reducing costly callbacks. Direct placement of concrete without re-handling also improves concrete quality.
In addition, concrete pumping does not require special mixes for optimum quality. A concrete pump will handle desired slumps and eliminate the need for excess water that can result in concrete cracking.
High-Rise Efficiency
The tallest buildings built in the past decade were pumped, even in excess of 1,900 feet high. Pumps can also achieve capacities in excess of 150 cubic yards per hour. Whether at ground level or on an impressive skyscraper, pumping concrete is the versatile and convenient way to get the job done right.
Going the Distance
Boom pumps are able to navigate up and over barriers as well as into confined spaces with other techniques to produce outcomes that are not feasible.
Furthermore, pumping concrete can also be a function of the distance to be conveyed to the material. Tunneling and mining are two excellent instances of when it is not possible to ignore the benefits of pumping.
"The BSA 14000 pumps 2,800 feet via slick line for the concrete lines of the North Avenue Tunnel," says Darrell Liebno, assistant project manager for Atlanta CSO Constructors (ACC). "The high pressure range of 3,190 psi and the high production quantities of 133 cubic yards per hour have significantly benefited us, considering the lengthy distances that the project requires the concrete to be placed." "The electrically powered BSA 2109H is rail-mounted, enabling high mobility in the Clear Creek Tunnel," adds Adam Stremcha, ACC project engineer. "Using electricity, this machine also offers zero emissions in its underground environment, making it environmentally friendly."
Site Specs:
- Atlanta's largest tunneling project
- Two tunnels will have a combined length of 43,800 feet and are anywhere from 160 to 320 feet below ground level
- Concrete is delivered above and below ground by trailer pump and tunneling concrete placing equipment
- 120,000 cubic yards of concrete pumped
- 4,000-psi concrete mix
From small trailer-mounted pumps to powerful line pumps and longest truck-mounted boom pumps, concrete contractors have a wide range of options for numerous applications, including:
- Mat pours
- Footings
- Indoor pours
- Slope paving
- High-rise buildings
- Mid-rise buildings
- Residential pours
- Light commercial
- Industrial
- Bridge decks
- Post tension slabs
- Tunneling
- Pools/shotcreting
- Patios
Concrete pump manufacturers such as Putzmeister America work with clients to determine the most suitable placement technique based on a project's full scope. Beton pumping provides effectiveness, quality and ultimate advantages from housing foundations to the highest structures in the world.
