The present application discloses a concrete crack prevention construction method and a construction device based on
temperature control, which relates to the field of concrete crack prevention and comprises the following steps: step 1, installing a heat exchange tube; the heat exchange tube comprises a plurality of unit sections, the unit section comprises a starting section, a
tail section and a plurality of connecting sections, one end of the starting section and the connecting section are both connected with a connecting
pipe 1, and the other end of the
tail section and the connecting section are both connected with a connecting
pipe 2, and the connecting
pipe 1 is used to connect with the connecting pipe 2; step 2, pouring concrete in the area to be poured; step 3, controlling the concrete temperature by injecting a heat exchange medium into the heat exchange tube; in the present application, when transporting and installing the unit section, the unit section can be split to reduce the length of the unit section, thereby facilitating the transportation and installation of the unit section, and when installing the unit section, the starting section, the
tail section and the plurality of connecting sections are connected into a whole through the connecting pipe 1 and the connecting pipe 2, so as to facilitate the introduction of the heat exchange medium into the entire unit section, thereby reducing the construction of the
water source station.
