The invention discloses a splicing construction method for a wind power mixed tower in a severe cold environment, which comprises the following steps of: paving an electric heating sheet on a splicing surface, coating a modified epoxy adhesive on the electric heating sheet, and extruding the modified epoxy adhesive to be in full contact with the electric heating sheet through gravity during splicing of concrete rings of the wind power mixed tower. And finally, the modified epoxy adhesive is heated and cured through an electric heating piece, and splicing construction of the wind power mixed tower concrete ring in the severe cold environment is completed. The modified epoxy adhesive is highly matched with the construction method, so that the modified epoxy adhesive can be cured to completely meet the bearing capacity requirement of the whole tower on the day of splicing construction in the severe cold environment (-50 DEG C to 0 DEG C), the construction period is the same as that of normal-temperature construction, and normal construction application of the wind power mixed tower in the severe cold environment is realized.
本发明公开了一种严寒环境下风电混塔拼接施工方法，首先在拼接面铺设电加热片，然后在电加热片上涂抹改性环氧胶粘剂，再通过风电混塔混凝土环拼接时的重力将改性环氧胶粘剂挤压至与电加热片充分接触，最后通过电加热片对改性环氧胶粘剂加热固化，完成严寒环境下风电混塔混凝土环的拼接施工。本发明通过改性环氧胶粘剂与施工方法的高度适配，使得严寒环境下(‑50℃至0℃)改性环氧胶粘剂拼接施工当日即可固化到完全满足整塔承载力要求，工期与常温施工一样，实现了风电混塔在严寒环境下的正常施工应用。
