| In recent years,steel sheet pile static pressure pile construction method,with its construction of no noise,no vibration,to minimize the impact of construction on the surrounding environment,the construction environment can be narrow,common manipulator pile driver can not start the construction site to carry out work and other advantages into the field of pile foundation,and has been widely praised.But as a new construction technique,its construction,the lack of quota hindered its rapid promotion,and this article in view of the steel sheet pile construction technique,the static pressure pile embedded construction methods based on nanning "three street two lane" project engineering construction need,the method of the key points of process principle,process,construction process and quality control are introduced,at the same time to meet the needs of the engineering budget,fill the blank of the process of construction norm,by using the principle of the quota establishment,through the workday realistic method quota calculation,and based on the principle of the statistical simulation norm is scientific and accurate analysis,studies the method of pile and pile construction quota of pull.Firstly,the paper introduces in detail the pressing principle,pressing method and its application under special and complicated working conditions,and studies the construction technology of steel sheet pile static pressing method,which provides certain support for subsequent projects adopting this method.Secondly,based on the analysis of the general situation and geological situation of the "Three Streets and two lanes" project in Nanning,the feasibility of the steel sheet pile static pressure piling method in the project is analyzed and studied according to the characteristics and difficulties of the project.Based on the engineering practice,according to the traditional quota compilation method,the preliminary quota data of steel sheet pile static pressure planting method is calculated.This paper analyzes the deficiency of the traditional method to compile quota.Finally,based on the original data collected in the project of "Three streets and two lanes",the software is used to obtain a large number of simulation data in accordance with the law.Based on the statistical simulation principle,the data simulation analysis is carried out to study and obtain the norm result of steel sheet pile static pressure planting pile construction method.Compared with the traditional method,this method can greatly improve the accuracy of the quota,and make the quota result have certain popularizing property,which is a reference for filling the blank of the construction quota. |
