[0025] In order to describe the prefabricated temporary road of the present invention in detail, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Figure 1 and Figure 2 The cross-sectional structure and top view structure of the prefabricated temporary road according to the embodiment of the utility model are respectively shown.

[0027] like Figure 1 and Figure 2 As collectively stated, the prefabricated assembled temporary road implemented by the present invention includes at least one temporary road section that can be assembled and assembled, and each temporary road section further includes a lower steel bar, an upper steel bar 2, and a concrete body 3 cast around the upper steel bar 2 and the lower steel bar 1; wherein, a plurality of reserved grooves 7 are provided on the concrete body 3, and a pre-embedded lifting ring 6 is provided in the reserved groove 7. The pre-embedded lifting ring 6 is welded and fixed to the lower steel bar 1 and accommodated in the reserved groove 7. When the temporary road is not hoisted, the setting of the reserved groove 7 will not affect the normal use of the temporary road. When the temporary road section needs to be hoisted, the hook of the external hoisting device can be buckled with the pre-embedded lifting ring 6, thereby simplifying the hoisting operation. The hoisting operation of the temporary road section can be completed by only a small crane or a hook machine.

[0028] Among them, the embedded lifting rings 6 can be set at the four corners of the concrete body 3. When the length of the concrete body 3 is long, the embedded lifting ring 6 structure can also be added in the length direction of the concrete body 3. The embedded lifting rings 6 are evenly or regularly distributed on the temporary road section, so that the temporary road section is evenly stressed during the lifting operation. It can be seen that the setting position and number of the reserved grooves 7 correspond to the embedded lifting rings 6.
