Anti-collapse rotary excavating pile construction device and construction method thereof
The invention relates to an anti-collapse rotary excavating pile construction device and a construction method thereof, and relates to the technical field of building construction. The anti-collapse rotary excavating pile construction device comprises an installation column and a pile casing for supporting pile holes, wherein the pile casing is arranged on the installation column in a sleeving mode, and a pouring hole is formed in the pile casing; a sprayer is movably arranged on the installation column, and a driving source for driving the sprayer to be inserted or separated from the pouringhole is arranged on the installation hole; and the anti-collapse rotary excavating pile construction device further comprises a concrete spraying machine, wherein the concrete spraying machine comprises a discharging pipe, and one end of the discharging pipe communicates with the sprayer. During construction, the installation column is coaxially and fixedly installed on a drilling rod of a rotaryexcavating drilling rig, the pile casing is arranged on the installation column in a sleeving mode, and then the installation rod and the pile casing extend into a collapsible soil layer through the rotary excavating drilling rig; the sprayer is driven to be inserted into the pouring hole through the driving source, the concrete spraying machine is started, and the sprayer pours concrete into thecollapsible soil layer outside the pile casing; and the purpose of fixing the collapsible soil layer is achieved, the collapse of the pile hole is prevented, and the construction quality is improved.
本申请涉及一种防塌陷旋挖桩施工装置及其施工方法，涉及建筑施工技术领域；包括安装柱和用于支护桩孔的护筒，护筒套设于安装柱上，所述护筒开设有灌注孔；所述安装柱上活动设置有喷头，所述安装柱上设置有用于驱动喷头插入或脱离灌注孔的驱动源；还包括混凝土喷涂机，所述混凝土喷涂机包括出料管，出料管的一端与喷头连通。施工时，将安装柱同轴固定安装在旋挖钻机的钻杆上，并将护筒套设于安装柱上，然后通过旋挖钻机将安装杆以及护筒伸入到易塌陷土层处；通过驱动源驱动喷头插入灌注孔内，启动混凝土喷涂机，喷头向护筒外的易塌陷土层内灌注混凝土；实现固定易塌陷土层的目的，预防桩孔塌陷，提高施工质量。
