液压静力压桩,是在软土地基上利用静压力将预制桩沉入土中的一种新工艺,与传统打入桩相比较有以下特点: 1.施工无振动、无噪音、无污染,适合于市区内尤其是医院病房、学校、办公楼附近及精密工厂车间扩建等工程的桩基施工; 2.消除打桩锤连续冲击荷载所引起的桩头桩身破坏,可降低工程成本; 3.操作方便,减少高空作业的不安全因素。压桩机的工作原理首先通过油路对夹持油缸2加压,夹紧桩段后油路转为对压桩油缸3加压,将桩1垂直压入地面。压桩油缸
Hydraulic static pressure pile is a new technology that uses static pressure to submerge prefabricated piles into soil on soft soil foundation. Compared with traditional driving piles, it has the following characteristics: 1. No vibration, no noise, no pollution during construction It is suitable for construction of pile foundations in urban areas, especially in hospital wards, schools, near office buildings, and expansion of precision factory workshops; 2. Elimination of pile head damage caused by continuous impact loads of pile drivers can reduce project costs; 3. Easy to operate, reduce the unsafe factors of high-altitude operations. The working principle of the pile driver first pressurizes the clamping cylinder 2 through the oil passage. After the pile segment is clamped, the oil passage is turned to pressurize the pile pressing cylinder 3, and the pile 1 is vertically pressed into the ground. Piling oil cylinder
