Construction method for steel-framework concrete wall of primary loop cabin of high temperature gas cooled reactor

Abstract

The invention relates to a construction method for a steel-framework concrete wall of a primary loop cabin of a high temperature gas cooled reactor, which belongs to the technical field of reactor structures. The method includes: arranging bearing steel posts and connecting beams according to the design requirements, fixing shielding cooling water pipes to form a steel-framework structural module, hoisting the steel-framework structural module to the position of the primary loop cabin of the high temperature gas cooled reactor, binding reinforcement bars, erecting a mould plate and concretingaccording to conventional construction procedures to form a lower-layer steel-framework concrete wall module, hoisting an upper-layer module on the lower-layer steel-framework concrete wall module, and cycling so to form the wall of the primary loop cabin of the high temperature gas cooled reactor. Using the construction method can shorten time of constructional critical paths, reduce cross workload on a construction site, relieve work intensity on the construction site and guarantee accurate execution of construction schedule while improve construction quality and shorten construction period.

Description

technical field [0001] The invention relates to a method for constructing a steel skeleton concrete wall of a primary circuit compartment of a high-temperature gas-cooled reactor, and belongs to the technical field of nuclear reactor structures. Background technique [0002] The high-temperature air-cooled reactor primary circuit compartment is a low-pressure ventilated containment containing the three main equipment of the reactor primary circuit system (reactor pressure vessel, steam generator shell and hot gas conduit), and is arranged in the nuclear island reactor building. The shielded cooling water system of the reactor is composed of a large number of scattered cooling water pipes. These water pipes are arranged inside the wall of the primary circuit cabin, and their installation is usually located on the critical path of the entire project construction. The construction progress of the primary circuit cabin directly affects the project. construction cycle. The tradi...

Problems solved by technology

[0007] The traditional construction method makes the construction site of the nuclear power plant a lot of work, there are many cross-operations between civil engineering and installation, the site work space is narrow and most of them are high-altitude operations. It will bring a huge amount of high-altitude operations, and the civil installation work of the primary circuit cabin will take a long time on the critical path, and its economy, safety and quality assurance requirements will be in an unfavorable competitive position
