Novel antiknock composite structure of underground engineering

Abstract

The invention discloses a novel antiknock composite structure of underground engineering. The novel antiknock composite structure of the underground engineering comprises a surrounding bed, a sealed fill layer and a lining layer, wherein the sealed fill layer is arranged between the surrounding bed and the lining layer. A low-strain framework hole concrete material is arranged in the sealed fill layer and generates active destruction under the explosion action. The lining layer is of an underground engineering reinforced concrete lining structure. According to the novel antiknock composite structure of the underground engineering, by filling the space between surrounding rock and the lining of the underground engineering is filled with the low-strain framework hole concrete material to form the sealed fill layer, under the action of the explosion, the sealed fill layer generates active energy dissipating destruction firstly, by adjusting the thickness of the fill layer, the corresponding relationship between the energy dissipating values of the fill material of different volumes and the impact energy can be determined, and therefore the completeness of the aggregate is kept; when agrouting reinforcing method and the like is adopted, the constitutive property of the material can be recovered within a short time, and the novel antiknock composite structure of the underground engineering has the capacity to exert in-situ rapid repair.

Description

technical field [0001] The invention relates to the field of anti-explosion structures, in particular to a novel anti-explosion composite structure for underground engineering. Background technique [0002] Due to the particularity and complexity of the underground environment where underground engineering is located, once a traditional underground engineering is affected by disasters (mainly sudden disasters such as earthquakes, terrorist attacks, and weapon strikes), the underground engineering structure and surrounding rocks are prone to overall collapse, resulting in Lost repair value. [0003] The existing explosion-proof structure of underground engineering cannot restore the structural properties of the material in a short time. Contents of the invention [0004] In order to solve the problems existing in the prior art, an embodiment of the present invention provides a novel anti-explosion composite structure for underground engineering. Described technical scheme...
