Energy pile and construction method thereof
The invention discloses an energy pile and a construction method thereof, and relates to the technical field of ground source heat pumps. A prefabricated pipe pile is arranged in the heat insulation section; the heat exchange section is arranged below the heat insulation section; u-shaped heat exchange pipes are arranged in the heat insulation section and the heat exchange section, and inlets and outlets of the U-shaped heat exchange pipes are located in the top of the heat insulation section. A first filler is arranged outside the prefabricated pipe pile; and a second filler is arranged in the heat exchange section. According to the energy pile and the construction method thereof, the heat exchange section is placed on the cement soil pile section on the lower portion of the root planting pile, due to the fact that the cement soil pile section has the small elastic modulus, under the same temperature variation, the additional temperature stress of a pile body during working can be effectively reduced, and then the influence on the bearing characteristic of the pile body is effectively reduced; therefore, safety and stability of the upper building are guaranteed. In the pile forming process of the heat exchange section cement soil pile, the heat conductivity coefficient is increased by adding materials into cement paste, and the heat exchange efficiency of the energy pile is improved; construction is convenient, and construction efficiency is high.
本发明公开一种能源桩及其施工方法，涉及地源热泵技术领域，包括隔热段和换热段；隔热段内设置有预制管桩；换热段设置于隔热段的下方；隔热段和换热段内设置有U型换热管，U型换热管的进口和出口位于隔热段的顶部；预制管桩外部设置有第一填充物；换热段内设置有第二填充物。本发明能源桩及其施工方法，将换热段放在根植桩下部水泥土桩段，由于水泥土桩段具有较小的弹性模量，在相同的温度变化量下，可有效减小工作时桩身附加温度应力，进而有效的降低对桩身承载特性影响，从而保障上部建筑物的安全稳定。换热段水泥土桩成桩过程中通过在水泥浆中添加材料增大导热系数，提高能源桩的换热效率；施工方便，施工效率高。
