Problems solved by technology

After the main structural frame is completed, the construction is carried out in sections. This construction mode has a long construction period, and at the same time has disadvantages such as poor construction conditions, high construction safety and quality risks, and low work efficiency, which is not conducive to high-standard traffic safety.

Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0044] The main plant structure includes a foundation part 100 and a plant superstructure 200 . The foundation part 100 includes foundation cap 10 , foundation short column 12 , steam turbine foundation 11 , 13 , pipe trench 14 , deep foundation 15 and embedded pipe 16 . The plant superstructure 200 includes a coal bunker room 1 , a deoxygenation room 2 and a turbine room 3 .

[0045] Specifically, such as Figure 5 As shown, the coal bunker room 1 is formed between the D column 20 and the C column 21, the deaeration room 2 is formed between the C column 21 and the B column 22, and the turbine room 3 is formed between the B column 22 and the A column 23.

[0046] Such as figure 2 As shown, S1 constructs the foundation cap and steam turbine foundation of the foundation...

Abstract

The invention provides a method for layered construction of a main power house. The method comprises a step S1 of constructing a foundation platform and a steam turbine foundation of a foundation portion of the main power house; a step S2 of constructing basic short columns of the foundation portion of the main power house; a step S3 of constructing a deep foundation and a shallow foundation of a main power house area, and performing backfill; a step S4 of constructing rough terrace of the main power house, and erecting an upper structure scaffold of the main power house on the rough terrace; and a step S5 of constructing an upper main body structure of a main power house main body. According to the construction method, construction of the rough terrace ahead of time is achieved, the problems that the construction site on the rainy days is muddy and raised dust is much on sunny days are solved, a steam engine room, a deaerator bay, a bunker bay and a boiler room are substantially constructed synchronously, steel structure construction is performed to a frame in front of a 15 m transfer layer, cross operation is avoided, construction progress is accelerated, and extremely favorable conditions are provided for high-standard delivery and installation.

Description

technical field [0001] The invention belongs to a construction method, in particular to a construction method of a power plant building project. Background technique [0002] The current construction process of the main factory building is roughly divided into two parts according to time, one is to build the foundation part of the factory building, and the other is to build the upper main structure of the factory building. [0003] In the foundation construction process, after the foundation is backfilled, the scaffolding of the upper structure is directly erected on the backfill soil, and the upper structure is erected and poured layer by layer. After the foundation is backfilled, a scaffolding board is laid on the backfilling foundation, so that a scaffolding is erected on the scaffolding board. However, in the construction environment with unfavorable weather conditions such as rainy days, the construction site will be muddy, and the setting will cause safety accidents c...
