Abstract
Description
Technical Field
[0001] The present invention relates to the field of integration of construction and energy, and particularly to a large-diameter non-displacement high-bearing-capacity low-carbon energy pile. Background Art
[0002] In the context of energy conservation and emission reduction, the construction industry, as an important source of global carbon emissions, is of particular significance in energy conservation and carbon reduction. Energy piles are an innovative technology that combines geothermal energy technology and deep foundations. They not only play the role of traditional pile foundations in supporting structures but also can serve as geothermal heat exchangers to absorb or release heat from the soil. Energy piles provide an effective and sustainable technical solution for the construction industry, which not only helps to achieve the goal of energy conservation and emission reduction but also can improve the economic and environmental benefits of buildings.
[0003] Currently, the main technical problem of energy piles in practice is the contradiction between structural load and thermal performance. For example, in traditional PHC (diameter 300 - 600 mm) pipe piles, heat exchange pipes are buried and backfilled with filling materials. This technology is easy to install, has a fast construction speed, and is not easy to damage the heat exchange pipes. However, it also has problems such as short pile diameter and low bearing capacity, which are prone to heat short-circuit and poor heat resistance. To improve the strength and heat resistance of the pipe piles, various reagents often need to be added to prepare high-performance concrete, which goes against the original intention of low-carbon environmental protection.
[0004] Therefore, on the one hand, the present invention uses solid waste materials as the main raw materials. While reducing the cement consumption, high-performance cementitious materials are obtained through various activation methods. At the same time, special microcapsules are added to be used as the main material of the pipe piles, making the pipe piles both low-carbon, high-strength, and heat-storing. On the other hand, the diameter of the pipe piles is enlarged, a special pile shoe is added, and the drilling - pipe sinking - grouting process is adopted, so that the overall structure of the pipe piles can not only be embedded in soft soil areas but also adapt to hard soil layers and can be closely integrated with the surrounding soil (including mechanical properties and heat conduction properties).
