Full-rotating drill and hydraulic vibration hammer synergetic shaft sinking method
The invention relates to the technical field of building foundation engineering construction, in particular to a full-rotating drill and hydraulic vibration hammer synergetic shaft sinking method. Thefull-rotating drill and hydraulic vibration hammer synergetic shaft sinking method comprises the following steps: 1, pile position setting out is conducted; 2, a orifice casing is inserted and struck; 3, a casing bottom pipe and a steel casing are mounted; 4, a full-rotating drill is mounted; 5, a hydraulic vibration hammer is mounted; 6, test-run of a machine is conducted; 7, a mortar conveyingpipe 90 is mounted, and the casing bottom pipe continues being drilled; and 8, concrete is poured, specifically, when drilling is conducted to a preset depth, hole cleaning and acceptance check are conducted, then a reinforcement cage is lowered in to a hole, then the concrete is poured, and the steel casing is pulled out from the hole, and a pile is formed. According to the full-rotating drill and hydraulic vibration hammer synergetic shaft sinking method, drilling into a very complex formation can be conducted, the drilling speed can be increased by four times or above, during hole drilling,because of advanced support of the steel casing, the situation of landslide of a hole wall or orificeis avoided, thus the pouring amount of the concrete can be decreased to the minimum, that is, thefilling coefficient is the minimum, and thus the material cost is saved.
本发明涉及建筑基础工程施工技术领域，具体涉及全回转钻机和液压振动锤协同凿井方法，其包括如下步骤：步骤一、桩位放样；步骤二、插打孔口护筒；步骤三、安装护筒底管和钢护筒；步骤四、安装全回转钻机；步骤五、安装液压振动锤；步骤六、试机；步骤七、安装输浆管90、护筒底管继续钻进；步骤八、浇灌混凝土：当钻至预设深度后，清孔、验收，然后向孔内下放钢筋笼，接着浇灌混凝土并将钢护筒拔出孔内，成桩。本发明的凿井方法可以钻进非常复杂的地层，而且钻进速度可以提高4倍以上，在钻孔时因为有钢护筒的超前支护，不会出现孔壁或孔口塌方的情况，使混凝土的浇灌量可以降到最低，即充盈系数最小，节约了材料成本。
