The full name of this project is "Prefabricated Concrete Multi-purpose Tower Crane Foundation", which won the national patent 10, and it is a scientific and technological achievement promotion project of the Ministry of Housing and Urban-Rural Development (20 10008), and a national spark plan project in 2007 [2007] No.769]. Main drafter of industry standard [No.JGJ/T197-2010 has been implemented in 201+0+1Ministry of Housing and Urban-Rural Development]; Appraised by Jiangsu Science and Technology Department; Won the third prize of building science and technology in Jiangsu province. This product is arbitrary and there is no competitive product in the market, which conforms to the development trend of energy saving, emission reduction and environmental protection in the construction field strongly advocated by the state and is supported by the government. At present, more than 70 cities in China 12 provinces have joined, with a total installed capacity of nearly 50,000 units.
Five advantages of Thaksin Foundation:
1.？ The safe and reliable design of assembled multi-purpose tower crane foundation adopts the optimized plane technology of tower crane foundation, which effectively improves the overturning resistance of tower crane foundation and is safer and more reliable to use. Since 2005, nearly 50,000 tests have been carried out in more than 70 cities including Jiangsu, Anhui, Shandong, Henan, Shaanxi, Sichuan and Hubei, and no safety and quality accident has occurred in coastal areas, plains and mountainous areas. This foundation is underwritten by Pacific Insurance Company, with a maximum insured amount of 600,000 yuan each.
2.？ Save time and worry. Because the assembled multi-purpose tower crane foundation is manufactured in the factory, it can be spliced and installed only by slightly treating the foundation at the construction site after it is transported to the site, which greatly shortens the time for on-site pouring (generally, it can be installed within 90 minutes). It not only saves the construction unit from binding steel bars and pouring; But also saves the trouble of inaccurate positioning of the screw; The most important thing is to omit the detection of concrete pressure test.
3.？ The traditional foundation with strong adaptability generally requires the foundation bearing capacity to reach 200Kpa, while the multi-purpose tower crane foundation adopts the extended foundation technology, which only requires the foundation bearing capacity to reach 80- 120 kPa. It can be installed in the form of non-burying, semi-burying and full-burying, and the foundation along the river and coastal areas can be used with a little treatment. It saves a lot of tedious steps and is easier, more convenient, faster and more accurate to use. Tower cranes below QTZ80 are applicable.
4.？ The cost-saving assembled multi-purpose tower crane foundation can be applied to different types of tower cranes because it is designed as a multi-purpose combination, making the foundation utilization rate as high as 100%. Reusable, low amortization cost, reducing rental cost.
5.？ If the traditional environmental protection tower foundation is not removed, it will leave hidden dangers and obstacles for underground municipal, telecommunications, gas and other pipelines, while the removal will leave concrete waste and pollute the environment. The assembled multi-purpose tower crane foundation has no construction waste, can be transported after installation, can be reused, saves sources of goods, saves energy and reduces emissions, protects the environment, and conforms to the sustainable development strategy.
Economic benefit analysis:
& ampnbsp& ampnbsp& ampnbsp？ Take QTZ40 tower crane foundation as an example: the cost of traditional cast-in-place tower crane foundation in East China is1.2000 yuan, and if it needs to be demolished by blasting, the total cost is1.6000 yuan, and it can only be used once, which is labor-consuming, time-consuming and costly for the construction unit and is not conducive to environmental protection; This precast concrete assembled tower crane foundation costs 9000 yuan and is leased to the construction party. The rent of each 40-type tower crane foundation in East China market is between 7000- 12000 yuan (including installation and demolition costs). Each foundation has a service life of 30 years and can be rented for about 40 times. It only takes 90 minutes to transport it to the construction site and install it in place, which saves time, effort and money for the construction party, is conducive to environmental protection and is supported by the government. For franchisees, promotion is easy and profitable. Precast assembled concrete is based on tower crane, which is time-saving, labor-saving, energy-saving, land-saving and environment-friendly. It is a green product of building construction in 2 1 century, which is conducive to building a resource-saving and environment-friendly society, fully conforms to the national building policy of energy conservation and emission reduction, and has high economic, social and environmental benefits.
