Backfill system used above built underground structure and construction method of backfill system
The invention relates to a backfill system used above a built underground structure. A side slope of a foundation pit formed by excavation is located above the built underground structure, and the backfill system comprises an enclosure structure formed at the two sides of the built underground structure in a constructed manner, a horizontal plate, a foam plate and a backfill soil layer; the top ofthe enclosure structure is partially exposed out of the side slope; the horizontal plate is formed at the top of the enclosure structure in a pouring manner, and the horizontal plate, the enclosure structure and the side slope define a filling space; the filling space is filled with the foam plate; the backfill soil layer is formed on the top of the horizontal plate in a backfill manner, and thetop face of the backfill soil layer is flush with the ground. According to the backfill system and the construction method, the problem that the built underground structure is prone to sedimentation and deformation in the backfilling process is effectively solved, the built underground structure is prevented from sedimentation by using backfilling materials with light mass, dynamic loads are prevented from being generated as much as possible, and the stability of the built underground structure is guaranteed.
本发明涉及一种用于已建地下结构上方的回填体系，开挖形成的基坑的边坡位于已建地下结构的上方，该回填体系包括：施工形成于已建地下结构的两侧且顶部部分露出边坡的围护结构；浇筑形成于围护结构的顶部的水平板，该水平板、围护结构和边坡围合形成填充空间；填充于填充空间中的泡沫板；以及回填形成于水平板的顶部的回填土层，且该回填土层的顶面与地面平齐。本发明有效的解决了已建地下结构在回填的过程中容易发生沉降、变形的问题，通过使用质量较轻的回填材料，避免已建地下结构发生沉降，尽可能避免产生动载荷，保证已建地下结构的稳定性。
