Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides a technical solution: the large volume concrete circulating cooling water pipe fast positioning construction method includes the following steps:
step 1, after the binding of upper and lower layers of reinforcing mesh sheets of the large-volume concrete is finished, arranging a circulating cooling water pipe and a positioning device between the upper and lower layers of reinforcing mesh sheets;
step 3, fixing the middle section of the circulating cooling water pipe by adopting a triple-branch combined positioning device;
and 6, repeating the step 4 and the step 5 in sequence to complete the positioning arrangement of the circulating cooling water pipe in the whole large-volume concrete.
