1、前言临时围堰工程,是在临海或河流建筑构造物时,为了能够干地作业,用于暂时截断水和土砂的流入所建造的临时构造物,建筑在临海的临时护岸也是其中的一种,在开挖河流的水闸工程时,也往往采用临时围堰工程。临时挡土构造物,从这个意义也可以说是一种临时围堰工程,这已经在“应用计算实例”4里详细叙述了其计算方法。因此,本文只对以截水为目的临时围堰工程,介绍其设计方法,列举计算实例。
1, Foreword Temporary cofferdam project is a temporary structure for temporarily blocking the inflow of water and earth sand in the temporary construction of a temporary shore revetment in a coastal area Species, in the excavation of the sluice project of the river, it is often used temporary cofferdam project. The temporary retaining structure, in this sense, can also be said to be a temporary cofferdam project, which has been described in detail in “Application Calculation Examples” 4. Therefore, in this paper, only the temporary cofferdam project for the purpose of water cut-off is introduced, and the design method is introduced. Examples are given.
