Modèle ya utilité epesaka raccordement spiral préfabriqué, oyo ezali na nzoto ya pile mpe na pointe ya pile. nzoto ya pile ezali na pile ya béton préfabriqué oyo ebwakami likolo mpe pile ya tuyau ya acier oyo ebwakami na se ya nzoto ya pile. Nsuka ya nzoto ya pile epesami na couvercle ya bouchon oyo ezali kobalola, mpe na nse ya nzoto ya pile ezali na likolo ya pile ya pile oyo ezali na likolo ya pile ya pile ezali kopesama na likolo ya pile na likolo ya pile ya pile ezali kopesama na likolo ya pile ya pile, ezali na likolo ya pile ya pile. Friction ya mabele ya pile. diamètre ya plaque ya acier annulaire ezali monene koleka diamètre ya nzoto ya pile na 1 à 5 cm, mpe likolo ya nzoto ya pile ebongisami na nzela ya bolai ya nzoto ya pile. groove spiral.
The utility model is suitable for construction in a region with poor geological conditions, and the pile body is pressed into the underground soil layer to ensure that the pile body is not damaged, and the annular steel plate is slightly larger than the diameter of the pile body, which can greatly reduce the side of the pile body into the process. The friction resistance accelerates the construction progress. The utility model greatly improves the construction speed, and at the same time ensures the Nzoto ya pile ebebi te, structure ezali simple, convenable mpe mbangu, mpe ebongi mpo na popularisation mpe kosalela.
