Problems solved by technology

In order to ensure safety, the foundation of the main pump evaporator requires high precision, and the foundation bottom plate has a large thickness, thick steel bar diameter, and dense arrangement due to safety performance requirements. The anchor bars of the embedded parts collide with the foundation steel bars, so that the embedded parts cannot be in place, affecting Installation accuracy
At present, the installation of the embedded parts of the main pump evaporator has problems such as low measurement accuracy, often affecting the measurement quality and work efficiency due to reinforcement construction obstacles

Embodiment Construction

[0033] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0034] This embodiment provides a method for installing and positioning an embedded part of a main pump evaporator.

[0035] like figure 1 As shown in the figure, in this embodiment, there are two sets of main pump evaporator embedded parts, which are respectively located on the -2.60m bottom plate of the nuclear reactor, symmetrically distributed, at 22.52° and 18.11° to the central axis of the reactor. There are 3 embedded parts in each group, and the steel bars of the bottom plate are Φ32 divided into three layers in the circumferential direction and the radial direction. Each embedded part has 16 anchoring steel bars, and the anchoring steel bars are Φ32.

[0036] The installation and positioning method of the embedded parts of the main pump evaporator includes the following steps:

[0037] The first step is to locate the control line of the emb...

Abstract

The invention discloses a main pump evaporator embedded part installing and positioning method which comprises the steps of base plate reinforcing steel bar position indoor adjustment, reinforcing steel bar position adjustment conflicting with embedded part anchoring reinforcing steel bars, main pump evaporator embedded part anchoring reinforcing steel bar position lofting, base plate reinforcing steel bar position lofting, reinforcing steel bar binding acceptance inspection and main pump evaporator embedded part supporting elevation adjustment. The main pump evaporator embedded part is preliminarily in place, the position of the embedded part is preliminarily adjusted, the elevation of the embedded part is accurately adjusted, and the position of the embedded part is accurately adjusted. By the adoption of the installation method, the one-time installation precision and efficiency of the high-precision embedded part are improved, labor consumption caused by improper installation and reworking due to steel bar position obstacles and the like is reduced, the embedded part can be rapidly and accurately installed in place, the construction efficiency is improved, and large economic benefits and social benefits are created.

Description

technical field [0001] The invention belongs to the technical field of civil construction, and relates to an installation and positioning method for embedded parts, in particular to an installation and positioning method for embedded parts of a main pump evaporator. Background technique [0002] The nuclear main pump of the nuclear reactor building is a pump in the primary circuit system of the nuclear island, which is used to drive the circulating flow of the coolant in the RCP (Reactor Coolant System) system. The main pump is located at the heart of the nuclear island. It is used to pump hot water into the evaporator to convert heat energy. It is the key to controlling the water cycle in the operation of the nuclear power plant. The single embedded part weighs 644kg, and each steam generator has a main pump. The construction quality of the main pump evaporator embedded parts is high, and it is the basic guarantee for the key equipment of the nuclear power plant. In order ...
