Embodiment Construction
[0037] The technical solutions in the present invention will be described in detail below in conjunction with the accompanying drawings.
[0038] combine figure 1 , figure 2 and image 3 As shown, using the AP1000 nuclear power plant sluice door frame installation method of the present invention, the specific steps for installing and fixing the door frame 1 and the door opening 2 of the sluice door are as follows:
[0039] The first step is to measure the size of the door opening 2. Due to the high sealing requirements between the door frame 1 and the door opening 2, in the AP1000 nuclear power plant, the door opening 2 is also made of metal material, and is fixedly connected to the door frame 1 by welding, and because the height of the door opening 2 Very large, exceeding the height dimension of the door frame 1. In this way, during the installation process of the door opening 2 , it is unavoidable to have dimensional deformation and deviation, especially along the width...

The invention belongs to the field of installation for nuclear power equipment, and specifically relates to an installation method for a door frame of a sluice gate in an AP1000 nuclear power station. In order to solve the problems of long construction time, high construction cost and low welding quality existing due to difficulty to control the dimensions between the door frame and a door opening and the need of filling lots of inert gases during argon tungsten-arc welding when the door frame of the sluice gate in the AP1000 nuclear power station is installed by adopting the abovementioned installation method. The invention discloses an installation method for a door frame of a sluice gate in an AP1000 nuclear power station. The installation method comprises the following steps: the first step of measuring the dimensions of the door opening; the second step of machining and treating the door frame; the third step of installing gaskets and auxiliary elements; the fourth step of hoisting the door frame; and the fifth step of connecting the door frame with the door opening. With the adoption of the installation method for the door frame of the sluice gate in the AP1000 nuclear power station, rapid and firm welding fixation between the door frame of the sluice gate in the AP1000 nuclear power station and the door opening can be realized, and control on the dimensions and position of the door frame can be improved, so that the installation quality of the door frame is ensured.
Description
technical field [0001] The invention belongs to the field of installation of nuclear power equipment, and in particular relates to a method for installing a door frame of a sluice gate of an AP1000 nuclear power plant. Background technique [0002] By setting water gates on the wall of the fuel transfer channel of the AP1000 nuclear power plant and the storage tank of the transportation container, the connection and separation between the spent fuel pool, the fuel transportation channel and the storage tank of the transportation container can be realized. Among them, during the normal operation of the AP1000 nuclear power plant, by controlling the opening and closing of the water gates at different positions, the liquid storage volume in the spent fuel pool, the fuel transportation channel and the storage tank of the transportation container can be controlled respectively, so as to meet different Working condition requirements. [0003] In the AP1000 nuclear power plant, th...
