Embodiment Construction

[0011] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] This embodiment is implemented on the premise of the technical solution of the present invention, and provides detailed implementation and specific operation procedures, but the protection scope of the present invention is not limited to the following embodiments.

[0013] Such as figure 1 As shown, the anchor system provided by the present invention includes a concrete base plate 1, an anchor block 2, a cable 3, an anchor 4, and a cable protection tube 5. The concrete floor is the basic structure of the nuclear power plant plant on the foundation, which directly bears the horizontal sliding force generated by the earthquake. Anchor block is a broad concept. It can be either a large-volume concrete block embedded i...

Abstract

The invention provides an anchorage system. The anchorage system comprises a concrete bottom plate, anchorage block bodies, cable ropes and anchoring parts. The anchorage block bodies are distributed on the two sides of the bottom plate. The anchoring parts are arranged at the two ends of the bottom plate and the anchorage block bodies on the two sides respectively. The anchoring parts at the two ends of the bottom plate and the anchoring parts on the anchorage block bodies on the two sides are connected through the cable ropes. The anchorage system can solve the problems in the prior art. When earthquakes happen, the slide force generated by the foundation bottom plate through slide displacement under the effect of the earthquakes is transmitted to the anchorage block bodies away from the bottom plate, the anchorage block bodies are high in anti-slippage capacity due to the fact that the anchorage block bodies are decoupled from a body structure and are stable rock mass or block bodies completely embedded in soil, the acting principle is similar to that of an anchorage device of a ship, the horizontal displacement of a structure foundation bottom plate under the effect of the earthquakes can be limited, and therefore the anti-slippage function is achieved.

Description

Technical field [0001] The invention relates to the field of safety structure design of nuclear power plant workshops, in particular to an anchor system that ensures that the nuclear power plant workshops do not suffer from overall slipping and instability under the action of an earthquake. Background technique [0002] There are many production-related workshops in nuclear power plants. Among them, earthquake-resistant Type I and Type II workshops have the highest importance and safety requirements. The seismic-resistant Type I workshops may contain radioactive materials from leaking out, or ensure that nuclear power plants will work in accidents. It plays an important role in the normal operation of various safety measures to alleviate the accident. [0003] According to the requirements of the current nuclear safety related regulations GB50267-97, buildings and structures of seismic class I or class II need to ensure the anti-slip stability of the foundation under the action of ...
