AI Technical Summary
During the excavation and construction of foundation pits, the existing concrete stormwater pipeline conflicts with the foundation pit space. The traditional method requires relocation of the stormwater pipeline, resulting in high construction period and cost, affecting the project progress and cost.
Design a flow diversion system, including setting up steel sheet pile support lines on both sides of the planned drainage pipe and erecting diversion steel pipes between them. The new rainwater well is located at the connection between the concrete rainwater pipe and the flow diversion steel pipe to ensure that the length of the flow diversion steel pipe is greater than the support. The spacing and elevation of the wire guards are consistent with the existing rainwater pipelines to achieve flow diversion.
This flow diversion system simplifies the construction process, does not need to first relocate the drainage pipeline, saves construction period, and passes through the support structure through the flow diversion steel pipe, achieving the normal operation of existing rainwater pipelines and reducing project costs.
