Not long ago, the national on-site exchange meeting on the application and promotion of carrier pile technology sponsored by the Science and Technology Development Promotion Center of the Ministry of Construction was held in Beijing. The new technology of carrier pile construction has attracted great attention from industry experts and construction enterprises. A representative of the Architectural Design and Research Institute told the reporter that if the carrier pile technology can be promoted nationwide, it will have a great shock to the whole construction industry. Reducing costs can win the market. Beijing Vanke Zitai Project, a high-grade residential area in Beijing. From the above-ground part, the buildings here seem to be no different from other residential areas, but the underground part is very mysterious. Possente's carrier pile technology was applied to the first phase 10 high-rise residence and two underground garages in this community. The diameter and average length of the carrier pile are smaller than those of ordinary manual digging piles, and the consumption of concrete and steel bars is much lower than that of manual digging piles. Therefore, the engineering cost of the carrier pile is only176,000 yuan, which is far lower than the cost of 348,000 yuan according to the conventional foundation construction technology, and the bearing capacity of the carrier pile is not inferior to that of the manual digging pile. In recent years, with the continuous improvement and development of patented technology of carrier piles in possente, nearly 1,000 large-scale engineering projects have been completed in China, with an output value exceeding 500 million yuan. The most classic example is Beijing North Sixth Ring Road, 13 bid section, and there are 23 bridges across the road and river. The patented technology of expansive composite foundation of Beijing possente Geotechnical Engineering Co., Ltd. is adopted for the treatment of high fill foundation at the bridge head, which saves about 25% investment for the country. Revolutionary breakthrough in piling technology According to the person in charge of Beijing possente Geotechnical Engineering Co., Ltd., carrier pile is a brand-new construction technology, which changes the traditional foundation treatment concept, selects the soil layer with stable lower soil layer and good soil quality as the reinforcement soil layer, takes the pile tip soil as the research object, and uses 35KN column hammer to make hole impact to consolidate the surrounding soil. After sinking the pipe to the design elevation, the pile end will continue to be filled and compacted. Take the penetration of three blows as the control index, and then pour hardened concrete, so that the soil in the area with a depth of 3-5 meters and a diameter of 2-3 meters below the pile tip can be most effectively reinforced and compacted, forming a carrier consisting of hardened concrete, filler and compacted soil in turn from inside to outside, and then placing a reinforcing cage, pouring concrete or placing a prestressed pipe joint. Using the carrier pile technology, the load test can be carried out after the piling work is completed 1 hour, while the ordinary piling work method needs to wait for the concrete to solidify and the soil to recover, and the test can only be carried out after 28 days according to the national standard. Therefore, this technology is not only simple to operate, and the construction quality is easy to control, but also greatly shortens the construction period, and there is no need for site precipitation during construction, thus reducing the engineering quantity and controlling the project cost to the maximum extent. It is no wonder that this technology will make people in the industry exclaim that if the carrier pile can be popularized nationwide, it will greatly reduce the foundation cost of buildings, comprehensively reduce the domestic construction cost, and will set off a great revolution in China's construction industry. The dream of eliminating construction waste has come true. The piling technology of buildings with patented technology of carrier piles in possente is different from that of general construction sites. With the rise and fall of the hammer, a black hole like a washbasin appeared on the ground, and bricks, gravel and concrete slag were dumped out at once. It is hard to imagine that the bearing capacity of this kind of pile foundation filled with construction waste is 20% to 30% higher than that filled with ordinary concrete if there are not nearly 1,000 successful examples such as Beijing North Sixth Ring Road, Tianjin Aquatic International Village and Shandong Liaocheng Jintai Building. The treatment of construction waste has always been a difficult problem in the construction industry. How to properly handle a large amount of construction waste generated in the process of engineering construction? How to create benefits without polluting the environment? Previously, some construction projects were exposed by the media. Because of underground landfill, the uneven settlement of building foundation has affected the quality and safety of the whole building. The carrier pile technology can turn waste into treasure after special tamping and compaction, which not only finds a place to live underground, but also reduces the cost of filler and ensures the quality and stability. So far, the carrier pile technology has accumulated hundreds of thousands of cubic meters of construction waste in China. After the project plan is fully implemented, the company plans to consume an average of 654.38 million cubic meters of construction waste every year. Tiehong Wang, chief engineer of the Ministry of Construction, pointed out in his written speech at the national on-site exchange meeting on the application and promotion of carrier pile technology that carrier pile technology is a model for the popularization and transformation of scientific and technological achievements, an innovative advanced technology and one of the important measures for developing circular economy. Facts have proved that the carrier pile technology can not only reduce the cost, improve the construction speed, but also absorb a lot of construction waste, and the construction process is pollution-free and low-noise, which can effectively protect the environment. Up to now, the carrier pile technology has been widely used in the fields of architecture, railways, highways, electric power, coal, petroleum, petrochemical and so on in 140 cities across the country, which has saved a lot of construction funds for the country and made outstanding contributions to the elimination of construction waste and the sustainable development of the construction industry.
