Specific embodiment
In order to preferably explain the present invention, come in the present invention is furture elucidated with specific embodiment below in conjunction with the accompanying drawings
Hold, but present disclosure is not limited only to following examples.
As shown in Figure 1 to Figure 3, a kind of low-temperature multi-effect devaporizer bearing installation method, comprises the following steps:
Step one, preparation of construction:
A, the repetition measurement of support base 1:Repetition measurement each support base 1, it is ensured that its absolute altitude, center, embedded part 5 and foundation bolt 3 are accorded with
Specification and design requirement are closed, meanwhile, repetition measurement also is carried out to the spacing between each adjacent support base 1, it is ensured that it reaches design will
Ask;The upper surface of the support base 1 is rectangle, before support base 1 is received, by the concrete dabbing of its upper surface, so as to
Good faying face can be formed when the later stage is to 2 back-grouting of bearing;
The inspection of b, the equipment of bearing 2:To each part of bearing 2 to scene check, it is ensured that not Short Item, lossless
It is bad;
Step 2, bearing 2 are pre-installed:
