QTZ80塔式起重机预制管桩基础的复核及施工监理要点

Recheck of precast tubular pile foundation and its construction supervision points for QTZ80 tower crane

建筑工地塔式起重机设置往往受地质条件和建筑物边线制约,有时在无法满足塔式起重机基础所要求的地基承载力的情况下,可以采取经济性好、效率高的混凝土预制管桩作为塔式起重机基础。因此,在审核塔式起重机预制管桩基础方案时,针对预制管桩结构的主要受力指标进行了复核验算,保证了塔式起重机的稳定性,为项目安全提供了强有力的保障。

The setting of tower crane in construction site is often restricted by the geological conditions and side boundaries,under the condition of being unable to meet the foundation bearing capacity required by the tower crane foundation,economic and efficient concrete precast tubular pile can be adopted for the tower crane foundation.When rechecking the scheme of tower crane tubular pile foundation,rechecking computations were carried out in view of the major force indexes of the precast tubular pile structure,thus the stability of tower crane is ensured,which provide guarantee for the project safety.
