Accompanying drawing explanation
Fig. 1 is that the structure without the prefabricated installation method of the prefabricated box-beam sections measuring tower of the present invention is shown
It is intended to.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art's reference
Description word can be implemented according to this.
As it is shown in figure 1,
The prefabricated installation method of a kind of prefabricated box-beam sections without measuring tower, comprises the following steps:
Step one, arranging fixing Side Template 1, described fixing Side Template 1 can play positioning action, adjacent
