Cast-in-place heat exchange pile-wall supporting structure and construction method thereof
The invention provides a cast-in-place heat exchange pile-wall supporting structure and a construction method thereof. The upper pile-wall supporting structure is poured through a concrete material, and the lower pile-wall supporting structure is poured through a mixture of graphene and concrete. The water outlet end of the heat exchange pipe is connected with the heat collector, and the water inlet end of the heat exchange pipe is connected with the geothermal pump. The construction method comprises the steps that a heat exchange pipe is fixed to a reinforcement cage, a pile body is constructed firstly, then a retaining wall is constructed, after grouting of a lower structure is completed, materials are replaced, grouting is conducted on an upper structure, a heat insulation layer is additionally arranged on the back-to-soil side of the upper retaining wall after a foundation pit is excavated, and then the cast-in-place heat exchange pile-wall supporting structure is formed. The lower retaining wall can improve the heat exchange efficiency, the heat insulation layer of the upper retaining wall can reduce energy loss, and after engineering is completed, the retaining wall serves as a permanent soil retaining structure of a slope and also serves as a heat exchange structure, so that the utilization efficiency of a supporting structure is improved.
发明提供一种现浇式热交换桩‑墙支护结构及其施工方法。上部桩‑墙支护结构采用混凝土材料浇筑，下部桩‑墙支护结构采用石墨烯和混凝土的混合物浇筑。换热管采用无缝钢管，换热管出水端与集热器相连，进水端与地热泵相连。所述施工方法为：将换热管固定在钢筋笼上，先施工桩体再施工挡墙，在下部结构注浆完成后更换材料对上部结构进行注浆，并在基坑开挖之后在上部挡墙背土侧增加绝热层，即形成现浇式热交换桩‑墙支护结构；本发明的下部挡墙可提高换热效率，上部挡墙的绝热层可减少能量损失，在工程完成之后，既作为坡地的永久挡土结构，又作为换热结构，从而提高支护结构的利用效率。
