Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0027] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "secured" to another element, it may be detachably or non-detachably fastened thereto. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expression...

Abstract

The invention relates to an AP1000 nuclear power conventional island throwing-striking-preventing structure and an assembly thereof. The throwing-striking-preventing structure comprises a hoop and a first stopping block; the hoop comprises a first hoop body which is provided with a first through hole; a first limiting part used for restraining the radial movement happening to a pipeline is formedin the inner wall of the first through hole; and the first stopping block is fixedly connected with the pipeline, and is matched with the first hoop body to form a second limiting part used for restraining the axial movement happening to the pipeline. According to the AP1000 nuclear power conventional island throwing-striking-preventing structure and the assembly thereof, by means of the first limiting part, the radial movement of the pipeline can be restrained; by means of the second limiting part, the axial movement of the pipeline can be restrained; the assembly number is small; the occupied space is small; and the arrangement of process pipelines and equipment in defined space can be performed easily.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant pipeline installation, in particular to an AP1000 nuclear power conventional island anti-shock structure and components thereof. Background technique [0002] With the rise of AP1000 (Advanced Passive, passive pressurized water reactor) nuclear power technology, many "passive safety systems" have put forward higher-level requirements for the safety performance of nuclear power plants. The burst of high-energy pipelines is a potential internal risk of nuclear power plants. One of the factors is that the huge slam force generated by the burst acts on the relevant structures, which is likely to cause nuclear safety accidents. How to prevent nuclear safety accidents that may be caused by high-energy pipeline bursts has become increasingly important. [0003] The traditional preventive structure is to restrict the radial movement of the high-energy pipeline by opening holes in the concrete ...
