Rock-fill concrete pouring device under vacuum condition and construction method thereof
The invention relates to a rock-fill concrete pouring device under a vacuum condition and a construction method thereof, and belongs to the technical field of water conservancy projects. The method comprises the steps that firstly, a site is leveled, a steel mold is erected to form a rockfill concrete pouring bin, a steel barrel is placed in the pouring bin, rockfill is stacked in the steel barrel, after the steel barrel is filled with the rockfill, the rockfill is leveled, then a top steel cover plate covers the steel barrel, and the top steel cover plate is tightly connected with the steel barrel; after the vacuum degree in the rock-fill concrete pouring bin meets the requirement, the grouting valve of the grouting pipe on the top steel cover plate is opened, self-compacting concrete is poured into the rockfill, the vacuum pump is still opened while grouting is conducted, grouting and air exhausting are conducted at the same time, and rock-fill concrete pouring under the vacuum condition is achieved. The defect that large gaps are easily formed in the traditional rock-fill concrete pouring process is overcome, the gaps are greatly reduced, the compactness of the rock-fill concrete is improved, and the mechanical property of the rock-fill concrete is improved.
本发明涉及一种真空条件下的堆石混凝土浇筑装置及其施工方法，属于水利工程技术领域。本发明首先平整场地，竖立钢模形成堆石混凝土浇筑仓，在浇筑仓内部放置钢桶，在钢桶内堆填堆石，当堆石堆填满后，对堆石进行整平，再盖顶部钢盖板，顶部钢盖板与钢桶的之间紧密连接；然后利用排气管进行抽气，当堆石混凝土浇筑仓内的真空度达到要求后，打开顶部钢盖板上的注浆管的注浆阀门向堆石中灌注自密实混凝土，注浆的同时仍打开真空泵，边注浆、边抽气，实现真空条件下的堆石混凝土浇筑。本发明克服传统堆石混凝土浇筑过程中易形成大空隙的不足，极大限度减小空隙的存在，提高堆石混凝土的密实性，改善堆石混凝土的力学性能。
