Light corrugated steel pile casing isolation filling-free karst cave cast-in-place pile forming construction method
The invention relates to the technical field of cast-in-place pile construction of building foundation engineering, and discloses a light corrugated steel pile casing isolation filling-free karst cavecast-in-place pile forming construction method. The method comprises the following construction steps that S1, cast-in-place pile drilling and hole forming are carried out, and a light corrugated plate coil is made into a pile casing shape; S2, the length of a light corrugated steel pile casing is obtained through cutoff; S3, after cast-in-place pile hole finishing, the light corrugated steel pile casing is mounted and is welded and fixed to an orifice pile casting through fixed steel bars; S4, a reinforcement cage is put into the light corrugated steel pile casing; S5, a perfusion guide pipeis mounted in a pile hole, and concrete is poured to form the pile; and S6, the orifice pile casting is lifted out, and the light corrugated steel pile casing is not pulled up and serves a part of apile body. The method has the following advantages that the pile side friction is effectively improved, the pouring quality of the pile body is guaranteed, operation is simple and convenient, and theconstruction cost is reduced.
本发明涉及建筑基础工程灌注桩施工的技术领域,公开了轻质波纹钢护筒隔离无充填溶洞灌注桩成桩施工方法,包括以下施工步骤:S1、灌注桩钻进成孔,将轻质波纹板卷制成护筒状;S2、截取轻质波纹钢护筒的长度;S3、灌注桩终孔后,安放轻质波纹钢护筒,并通过固定钢筋焊接固定在孔口护筒上;S4、在轻质波纹钢护筒内下放钢筋笼;S5、在桩孔内安放灌注导管,灌注混凝土成桩;S6、将孔口护筒吊出,轻质波纹钢护筒不起拔,作为桩身的一部分;具有以下益处:有效提高桩侧摩阻力,保证桩身灌注质量,操作简便,降低施工成本。
