Steel structure hoisting construction method for incineration room and purification room of power plant

Abstract

The invention discloses a power plant incineration room and purification room steel structure hoisting construction method which comprises the following steps: step 1, partitioning: an incineration room area on the west side of a tower crane for hoisting equipment is defined as a first area, and an area on the north side of the incineration room is defined as a second area; the south area of the tower crane is defined as a third area, the north area is defined as a fourth area, and the tower crane area is defined as a fifth area; truss assembling sites are built on the west side, the north side and the east side of the plant; 2, equipment is selected, wherein a crawler crane is selected as steel structure hoisting equipment, and a truck crane is selected as crawler crane mounting and dismounting and steel structure assembling equipment; 3, construction is conducted, specifically, hoisting construction of the first area and the second area is conducted through a crawler crane; after construction in the second area is completed, the crawler crane is moved to the fourth area for hoisting construction; when a first-area steel structure and a second-area steel structure are constructed, hoisting construction of a third-area steel structure is carried out when a tower crane is idle; and after the tower crane is dismantled, the truck crane is used for hoisting the five-area steel structure. The construction method has the advantages of being short in period, capable of saving construction cost and high in safety.

Description

technical field [0001] The invention relates to the technical field of steel structure construction, in particular to a construction method for hoisting steel structures in incineration rooms and purification rooms of power plants. Background technique [0002] At present, my country's urban waste has become an important issue affecting the development of my country's cities. my country's waste production is huge, and now it is mainly treated by waste incineration for power generation. The boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with certain thermal energy. The hot water or steam generated in the boiler can be directly used for industrial production. It can also be converted into mechanical energy through steam power devices, or into electrical energy through generators. The commonly used mechanical grate furnace...

Problems solved by technology

[0005] The technical problem to be solved is: at present, steel structure construction, incineration equipment installation, and flue gas treatment equipment installation are generally carried out successively. The equipment in the plant is installed by tower cranes, and the steel structure is installed by crawler cranes. The method of sequential construction has a long period and high construction cost, which cannot meet the requirements of the construction period
