Embodiment Construction
[0020] In order to avoid the waste of time and manpower caused by manual handling of scaffolding and installation items, the construction method of the present invention first assembles the scaffolding outside the site, and temporarily fixes the installation items on the scaffolding, and then lifts the scaffolding and installation items into the installation as a whole On-site, thereby saving time and manpower for moving scaffolding and installing items. The construction method of the present invention can be extended to the entire nuclear power plant, and is especially suitable for densely installed areas such as pipe galleries. In the following, the construction method of the present invention will only be described by taking the pipe gallery as an example, but the construction method of the present invention can also be used in other installation areas.
[0021] see figure 2 and Figure 12 As shown, the scaffold used in the implementation method of the present invention ...

The invention discloses a construction method, which comprises the following steps of: assembling a multilayer scaffold off site; temporarily fixing installation items on the scaffold layer by layer; integrally hoisting the scaffold and the installation items to a construction site; sealing the top of a civil room; and installing the installation items on site from a high layer to a low layer, and detaching the scaffold till the installation is finished. Compared with the prior art, the construction method has the advantages that: the scaffold is assembled off site, the installation items are temporarily fixed on the scaffold, and then the scaffold and the installation items are integrally hoisted to the installation site, so that manpower and time for carrying the scaffold and the installation items can be saved, and the problem that the installation items are difficultly introduced after a plant is built does not exit; and the operation of erecting the scaffold does not need to be performed on the construction site, so that the construction environment is improved, the construction period can be shortened, the construction investment is reduced, the construction cost of a nuclear power plant is reduced, and the method plays a positive role in improving the economical efficiency of the nuclear power plant.
Description
technical field [0001] The invention relates to the field of installation and construction of industrial facilities such as nuclear power plants, in particular to a convenient construction method similar to dense installation areas such as pipe galleries. Background technique [0002] At present, the construction of domestic nuclear power plants generally adopts the traditional civil construction and installation construction organization mode, and is constructed according to the preset construction sequence, that is, most of the plant structures are built first, and then the scaffolding equipment is manually transported into the plant and erected. Scaffolding, and finally the installation items are manually introduced and installed in the factory building. The above-mentioned construction method requires a lot of time and manpower in handling scaffolding equipment, setting up scaffolding on site, and introducing installation items, so that the construction process has disad...
