Deep foundation pit slope structure type support construction method
The invention discloses a deep foundation pit slope structure type support construction method, and belongs to the technical field of constructional engineering. According to the method, the foundation pit side slope of the stepped structure is excavated, holes are drilled in the longitudinal stepped face of the side slope, soil nails are drilled into the drilled holes, then grouting is conducted, the soil nails are firmly limited and fixed in soil, then the meshes are connected with anchor heads of the soil nails in a spot welding mode, the meshes are arranged on the slope surface to form a huge mesh plate, and the mesh plate is arranged on the slope surface. The meshes are filled with sprayed fine aggregate concrete and attached to the soil slope surface, the concrete and the mesh plate form a huge supporting plate which is tightly attached to the slope surface through supporting of soil nails, the cement layer on the transverse step surface and soil below the cement layer abut against each other to form a whole, and the supporting stability is improved. By the adoption of the technical scheme, the slope supporting strength is high, safety is good, the construction method is simple and convenient, and cost is low.
本发明公开了一种深基坑边坡结构式支护施工方法，属于建筑工程技术领域。本发明的方法，通过开挖阶梯形结构基坑边坡，在边坡纵向阶梯面上钻孔，并利用土钉钻入钻孔内部，然后灌浆，使得土钉牢牢限位固定在泥土中，然后利用网片与土钉锚头点焊连接，使得网片排布在坡面上形成一个巨大的网片板，再利用喷射的细石混凝土填充网孔处并与泥土坡面贴附，混凝土与网片板形成一个巨大的支护板利用土钉的支撑紧附在坡面上，通过横向阶梯面上的水泥层与下方的泥土相抵支撑形成一个整体，提高了支护的稳定性。采用本发明的技术方案，边坡支护强度高，安全性好，施工方法简单、便捷，且成本低。
