Construction method of deep gravel cut-off seepage ditch under loose muck condition
The invention belongs to the technical field of seepage interception engineering, and particularly discloses a construction method of a deep gravel seepage interception ditch under the condition of loose muck. The method comprises the following steps: cleaning and leveling a site; building a guide wall according to a design route; piles are arranged along the cut-off ditches, and pile numbers are compiled; measuring and setting out the pile positions and marking the pile positions point by point; performing first pile hole-forming construction in the guide wall according to the mark; after pile hole slag removal, a connector pipe is inserted, and a first pile is completed; finishing a third pile according to the jump hole of the first pile; hole forming construction of a second pile is completed according to hole forming of the first pile; an arc-shaped cutter drill bit is adopted to cut off muck, close to the joint pipes on the two sides, in the second pile; the second pile is filled with gravels through a guide pipe; the fifth pile is completed according to hole jumping of the first pile; gravel filling of the fourth pile is completed according to the second pile; after part of gravel is filled in the third pile, the connector pipe is pulled out, and filling continues; and circularly constructing according to the sequence until gravel filling of all the piles is completed. The method has the advantages of being low in cost, safe in construction, short in construction period and high in universality.
本发明属于截渗工程技术领域，具体公开一种松散渣土条件下深碎石截渗沟的施工方法。该方法是先场地清表并平整；按设计路线修筑导墙；沿截渗沟排桩及桩号编制；对各桩位测量放线并逐点标记；根据标记在导墙内进行第一根桩成孔施工；桩孔清渣后插入接头管，完成第一根桩；按第一根桩跳孔完成第三根桩；按第一根桩成孔完成第二根桩的成孔施工；采用弧形切刀钻头切除第二根桩内靠近两侧接头管的渣土；采用导管向第二根桩内填筑碎石；按第一根桩跳孔完成第五根桩；按第二根桩完成第四根桩的碎石填筑；向第三根桩内填筑部分碎石后拔出接头管并继续填筑；按前述依次循环施工直至完成全部桩的碎石填筑。本发明具有成本低、施工安全且工期短、普适性强的特点。
