Rich thick sand layer geological static pressure pile hole-guiding device and construction method
The invention discloses a rich thick sand layer geological static pressure pile hole-guiding device and construction method. The rich thick sand layer geological static pressure pile hole-guiding device includes a drill pipe, a drill bit, drill teeth, high-pressure spray nozzles, a water inlet pipe, a water pump, a slurry discharge pipe and a slurry pump. The drill bit is provided with the drill teeth and the high-pressure spray nozzles. The drill teeth drill into soil to form fine particles, the high-pressure spray nozzles shoot water to the bottom of holes to form slurry in the holes, the slurry in the holes can be discharged through the slurry discharge pipe, hole-guiding drilling operation can be performed under the rich thick sand layer geological condition, equipment is simple, costis saved, floor area is small, and noise pollution to the surrounding environment is little. The rich thick sand layer geological static pressure pile hole-guiding construction method using the rich thick sand layer geological static pressure pile hole-guiding device can minimize the disturbance to the sand layer geology, eliminate the impact of the sand layer geology on the friction resistance inthe pressing process of precast concrete piles, prevent the collapse of pile holes, and ensure the quality of pile foundations.
本发明公开了一种富厚砂层地质静压桩引孔装置及施工方法，装置包括：钻杆、钻头、钻齿、高压喷头、进水管、水泵、排浆管以及泥浆泵，本装置通过钻头上设置钻齿和高压喷头，钻齿将土壤钻进形成细小颗粒，高压喷头向孔底射水形成孔内泥浆，通过排浆管将孔内泥浆排出，可在富厚砂层地质条件下进行引孔钻进作业，设备简单，成本节约，占地面积小，对周围环境噪音污染小。使用本装置的本施工方法可最大程度的减少对砂层地质的扰动、消除砂层地质对预制混凝土桩下压过程中摩阻力的影响，防止桩孔坍塌，确保桩基的质量。
