Blind hole structure and construction method thereof
The invention relates to a blind hole structure and a construction method thereof. The blind hole structure comprises a buried piece, a protective cover and an air extraction joint, wherein the buriedpiece is embedded in a concrete structure, the protective cover is arranged at the top of the buried piece in a covering manner, and the protective cover comprises a cover edge attached to the edge of the top of the buried piece; and the air extraction joint is connected to the protective cover, and the air in the protective cover is extracted through the air extraction joint, so that the cover edge of the protective cover is tightly attached to the edge of the top of the buried piece, and after the air extraction is finished, a plugging head is inserted and blocked at the air extraction joint. According to the blind hole structure, the protective cover is arranged at the top of the buried piece in a covering manner, the cover edge of the protective cover and the edge of the top of the buried piece are attached and fixed, the buried piece is isolated and protected, and the concrete is prevented from falling into the buried piece in the pouring process; and the air in the protective cover is extracted through the air extraction joint, so that negative pressure is formed in the protective cover, the cover edge is tightly attached to the edge of the top of the buried piece, leakage is prevented, and the tight fit of the cover edge of the protective cover and the edge of the top of the buried piece is further enhanced.
本发明涉及一种盲孔结构及其施工方法，其中盲孔结构包括：预埋于混凝土结构中的埋件；罩设于埋件顶部的防护罩，防护罩包括贴设于埋件顶部的边沿的罩边；连接于防护罩的抽气接头，通过抽气接头抽离防护罩内的空气，使得防护罩的罩边紧密贴设固定于埋件顶部的边沿；待抽气完毕后，插设封堵于抽气接头的封堵头。本发明采用防护罩罩设于埋件顶部，且防护罩的罩边和埋件顶部的边沿贴设固定，对埋件进行隔离防护，防止浇筑过程中混凝土落入埋件内。通过抽气接头处抽取防护罩内的空气，使得防护罩内呈负压，罩边紧密贴设于埋件的顶部边沿，防止漏气，进一步加强防护罩的罩边与埋件顶部的边沿的紧密贴合。
