Construction structure and method for new pipeline close to existing pipeline
The invention relates to the technical field of underground pipeline construction, and provides a new pipeline construction structure close to an existing pipeline, the new pipeline construction structure comprises a foundation trench, a supporting plate and a prefabricated supporting piece, and the foundation trench is excavated in one side of the existing pipeline; first grooves are further formed in the top ends of the soil bodies on the two sides of the foundation trench, and third grooves are further formed in the edges, close to the soil bodies on the two sides, of the bottom of the foundation trench; the supporting plate comprises a soil retaining plate, a top pressing plate, a pressing strip, a bottom pressing plate and an anti-sliding plate which are prefabricated into an integrated structure. The retaining plates are vertically attached to a soil body on the side wall of the foundation trench, anchor rods are arranged on the retaining plates close to the supporting plate of the existing pipeline, and the anchor rods are anchored into the soil body around the existing pipeline. The top pressing plate is laid in the first groove; the anti-sliding plate is inserted into the third groove; the prefabricated supporting pieces are arranged in the foundation trench at intervals in the length direction of the foundation trench. The construction safety of the foundation trench can be effectively guaranteed through the supporting plate; and the installation precision and the construction efficiency of the newly-built pipeline are improved.
本申请涉及地下管线施工技术领域，提供了一种临近既有管线的新管线施工结构，包括：基槽、支护板以及预制支撑件，基槽开挖于既有管线的一侧；基槽的两侧的土体顶端还设置有第一凹槽，基槽的底部靠近两侧土体的边缘还设置有第三凹槽；支护板包括预制为一体结构的挡土板、顶压板、压条、底压板和抗滑板；挡土板竖立的紧贴基槽的侧壁的土体，靠近既有管线的支护板的挡土板上设置有锚杆，锚杆锚入既有管线周围的土体中；顶压板铺设于第一凹槽内；抗滑板插入第三凹槽；预制支撑件沿基槽的长度方向间隔设置于基槽内。本发明通过支护板可有效保证基槽的施工安全；提高了新建管线的安装精度和施工效率。
