中文摘要:基于高压旋喷成桩机理以及目前市场对大桩径施工的需求,针对普通旋喷施工成桩直径小、排泥污染环境等问题,研制了一款能适应新工艺、新工法且能解决上述问题的十一管喷头。通过对喷头在地下工作的实际状态进行分析,新研制的十一管喷头具有地内压力检测,专用通道排泥及浆管通径大等特点,可以实现大桩径施工,泥浆统一回收及避免施工对周边建筑的扰动。

Development of 11 pipe high pressure rotary jet nozzle
Abstract:Based on the mechanism of high-pressure rotary jet pile formation and the current market demand for large pile diameter construction, it is necessary to develop a spray nozzle that can adapt to new processes and methods and solve the problems of small pile diameter, mud discharge and environmental pollution during the construction process of ordinary rotary jet. According to the analysis of the actual working condition of the nozzle under the ground, the newly developed 11-pipe nozzle has the characteristics of in-ground pressure detection, mud discharge in special channels, large diameter of slurry pipe, etc., which can realize large pile diameter construction, uniform mud recovery and avoid disturbance of construction to surrounding buildings.
