Construction technology for slurry retaining wall cast-in-place pile of rotary drilling rig
The invention belongs to the technical field of rotary drilling rig construction, and provides a rotary drilling rig slurry retaining wall cast-in-place pile construction technology which comprises the steps that a site is leveled; a first pile, an orifice mud pit, a second pile and a mud pit are sequentially arranged on one side of the rotary drilling rig; the rotary drilling rig excavates a first pile hole, a mud pit, an orifice mud pit and a second pile hole; steel pile casings are installed in the first pile hole and the second pile hole; drainage grooves are dug in the protection wall of the first pile hole and the protection wall of the second pile hole, and the drainage grooves communicate with the hole opening mud pool; drilling and cleaning holes by the rotary drilling rig; a reinforcement cage and a guide pipe are put into the first pile hole and the second pile hole; and concrete is poured, after concrete pouring is completed, the steel casing is pulled out of the pile hole, and a pile foundation is formed. According to the method, a traditional slurry wall protecting technology is changed from a single-pile three-slurry-pit technological process to a double-pile double-slurry-pit technological process or a four-pile three-slurry-pit technological process, the labor cost and the mechanical cost are greatly saved, the efficiency is improved, and the engineering cost is reduced.
本发明属于旋挖钻机施工技术领域，提供了一种旋挖钻机泥浆护壁灌注桩施工工艺，包括：场地平整；在旋挖钻机的一侧依次设置第一桩、孔口泥浆池、第二桩和泥浆池；旋挖钻机开挖第一桩孔、泥浆池、孔口泥浆池和第二桩孔；向第一桩孔内和第二桩孔内安装钢护筒；在第一桩孔的护壁上和第二桩孔的护壁上挖引流槽，引流槽与孔口泥浆池相互连通；旋挖钻机钻进及清孔；向第一桩孔内和第二桩孔内下放钢筋笼和导管；浇筑混凝土，混凝土浇筑完成后将钢护筒从桩孔当中拔出，形成桩基。本发明将传统的泥浆护壁工艺由单桩三泥浆池的工艺流程转变为双桩双泥浆池或者四桩三泥浆池的工艺流程，大大节约人工和机械成本，提高了效率，降低了工程成本。
