Embodiment Construction

[0014] As shown in Figure 1, the cavern 6 of the civil air defense cavern with energy-absorbing, waterproof and compression-resistant functions consists of a reinforced concrete lining 1 from inside to outside, an energy-absorbing and waterproof filling material layer 3, and a rock-soil layer 4. , the reinforced concrete lining 1 and the energy-absorbing waterproof filling material layer 3 are anchored together with the surrounding rock and surrounding soil layer 4 with a number of evenly distributed anchor rods 5 . The reinforced concrete lining structural part 1 is a prefabricated part, generally composed of 4-8 prefabricated arc-shaped reinforced concrete structural parts 1-1 splicing; the reinforced concrete lining structural part 1 of this embodiment consists of 4 prefabricated curved reinforced concrete The pieces are composed of 1-1 stitching.

[0015] As shown in Fig. 2, the width L of the prefabricated curved reinforced concrete structure 1-1 is generally 800-1000mm. ...

Abstract

The invention relates to a civil defense cavern, in particular to a civil defense cavern with the functions of absorbing energy, preventing water and resisting pressure. The civil defense cavern comprises a cavern, wherein the inner wall of a cavern rock-soil layer is lined orderly with an energy-absorbing waterproof filling material layer and a reinforced concrete lining piece; the energy-absorbing waterproof filling material layer and the reinforced concrete lining piece are anchored to the inner wall of the rock-soil layer by a plurality of anchor rods. The invention has the advantages that: the civil defense cavern has the effects of absorbing energy once, paring force twice, releasing pressure and transloading, which can reduce the energy acting on a cavern lining structure to the utmost extent, so as to maintain the stability of the cavern in wartime; and the civil defense cavern has the functions of dynamically loading, paring force, releasing pressure and transloading stress under the action of great explosion impact and dynamic load, so as to maintain the cavern in good conditions.

Description

technical field [0001] The invention relates to a civil air defense cavern, in particular to a civil air defense cavern with energy-absorbing, waterproof and pressure-resistant functions. Background technique [0002] The civil air defense project is an important project for protection that is first considered in the construction of various countries in the world. At present, in the design and construction of civil air defense caverns, ordinary reinforced concrete rigid structures are still used, but the strength and rigidity of the structure are greater than those of general agricultural projects. After completion, some projects are difficult to meet the requirements of civil air defense projects. Contents of the invention [0003] The object of the present invention is to provide an air-proof cavern with energy-absorbing, waterproof and pressure-resistant functions. It has the functions of primary energy absorption, secondary cutting force, pressure relief, and reloadin...
