Description

  The present invention relates to a structure wall reinforcing structure for a treatment pond.

  For example, in processing ponds such as sedimentation ponds and concentration tanks, the civil engineering enclosure walls are made of concrete with reinforcing bars, which ensures the safety of the assumed strength.

Problems to be solved by the invention

However, such a skeleton wall often shows that the concrete base and internal rebar are eroded by hydrogen sulfide etc. due to aging, and the entire wall is weakened. If an earthquake strikes such a place, it is assumed that the fragile body wall will collapse relatively easily.
For this reason, the concrete wall is replenished to the inner surface of the existing civil engineering cabinet wall to compensate for erosion, and the thickness is increased to take measures to reinforce it, or to renew the housing wall instead of reinforcing it. However, any of these methods is not preferable because it is not only a major measure but also increases the cost and takes time for construction.
In view of the above, an object of the present invention is to provide a casing wall reinforcing structure for a treatment pond that can easily and effectively prevent such a danger of collapse.

Means for solving the problem

In order to solve the above-mentioned problem, the invention described in claim 1 counters the collapse of the frame wall by bridging the reinforcing material between the existing frame walls arranged opposite to the treatment pond such as a sedimentation pond. It was configured as follows.
The invention described in claim 2 is the one described in claim 1, wherein the reinforcing material is provided alongside the constituent member. Here, the component member is a member configured in a scum removing device or a linear reciprocating sludge scraping device, for example, in the case of a sedimentation basin.

The invention's effect

  According to the present invention, since the reinforcing material is arranged between the existing frame walls arranged facing the treatment pond such as the sedimentation pond to counter the collapse of the frame wall, the risk of collapse can be simplified. And it becomes possible to prevent effectively.
