Deep surface soil stratum large-diameter shaft raise-boring construction method
The invention discloses a deep surface soil stratum large-diameter shaft raise-boring construction method. The method comprises the following steps of (A) shaft construction preparation work; (B) the rotary drilling rig excavates a surface soil section to form a pilot well, and the pilot well is excavated to a bedrock section; (C) backfilling the pilot well with concrete; (D) full-well deep guide hole construction; (E) performing raise boring on the bedrock section, and performing primary boring; (F) reaming the surface soil section; (G) well wall supporting; through newly designed construction steps, the advantages of a rotary drilling rig and the advantages of a raise boring machine are combined together, and the shaft construction technology which is safe, reliable, short in construction period and low in engineering cost is formed; according to the method, a surface soil layer is replaced by concrete or similar concrete with proper strength, so that the whole well depth is suitable for a raise boring process, and the purpose of safely, quickly and economically constructing a shaft is achieved.
本发明公开了深表土地层大直径井筒反井施工方法，包括如下步骤：(A)井筒施工准备工作；(B)旋挖钻机开挖表土段形成导井，导井开挖至基岩段；(C)混凝土回填导井；(D)全井深导孔施工；(E)基岩段反井扩孔，一扩成井；(F)表土段扩孔；(G)井壁支护；本发明通过新设计的施工步骤，将旋挖钻机和反井钻机各自的优点结合在一起，形成一套安全可靠、工期短且工程费用低的井筒建设工艺；本发明是将表土层换成强度合适的混凝土或类混凝土，以便全井深适用反井钻工艺，达到安全、快速、经济建设井筒的目的。
