<p>The present invention relates to a prefabricated collecting well which minimizes the deformation of a lower plate and damage to the lower plate caused by the pressure of underground water and is easy to carry to prevent accidents. To achieve this, in the prefabricated collecting well, a plurality of intermediate and upper plate members is joined together into an intermediate plate and an upper plate and a lower plate member makes up a lower plate joined to the bottom of the intermediate plate. The lower plate member is opened by the bottom and has a space inside, wherein a plurality of re-bars is joined to the lower plate member to be integrated by concrete. A pair of carrying rings joined to the re-bars is provided on the outer circumference of the lower plate member. A pair of escape prevention parts is joined to the intermediate plate above the carrying rings at a distance from each other in order to prevent an escape of a wire joined to the carrying rings.</p> |
