Load reduction construction method for filling pipe gallery
The invention provides a filling pipe gallery load reduction construction method capable of reducing pipe gallery load and reducing pipe gallery cracking, and relates to the technical field of pipe gallery construction. The invention discloses a filling pipe gallery load reduction construction method. The method comprises the steps that a cement soil cushion layer pre-embedded with anti-floating tie bars is poured in a pipe gallery groove; after the strength of the cement soil cushion layer meets the requirement, a pipe gallery with the top of an arch structure is assembled in the pipe gallery groove, the pipe gallery is formed by assembling and enclosing corrugated steel plates with corrugations extending in the length direction of the pipe gallery in a segmented mode, and a gap is reserved between the bottom face of the pipe gallery and the cement soil cushion layer to form a foundation pouring space; and the pipe gallery groove is backfilled, and when the pipe gallery groove is backfilled to the top elevation of the pipe gallery, an EPS load reducing plate capable of covering the orthographic projection range of the cement soil foundation is horizontally laid on the top of the pipe gallery. The bearing capacity and stability of the pipe gallery are improved, and cracking and differential settlement of the pipe gallery can be reduced.
本发明是提供一种可减轻管廊负荷，减少管廊开裂情况发生的填土管廊减荷施工方法，涉及管廊施工技术领域。填土管廊减荷施工方法，包括在管廊槽内浇注预埋有抗浮拉筋的水泥土垫层；待水泥土垫层的强度达到要求后，在管廊槽内拼装顶部为拱形结构的管廊，所述管廊采用波纹沿管廊长度方向延伸的波纹钢板分节拼装围合而成，所述管廊的底面与水泥土垫层之间留有间隙以形成基础浇注空间；对管廊槽进行回填，其中，当回填至管廊的顶部标高时，在管廊的顶部水平铺筑可覆盖水泥土基础正投影范围内的EPS减荷板。本发明提高了管廊的承载能力和稳定性，可以减少管廊开裂和不均匀沉降的发生。
