AI Technical Summary
In soft rock formations, the traditional dispersed layout of intake and distribution wells leads to a large amount of excavation work, weak structure, insufficient deformation resistance and complex pipeline nodes, which affects the water pump's suction stability and equipment reliability.
The intake well and distribution well are integrated into a three-in-one well, combined with reinforced concrete isolation components and large-section connecting tunnels to form an integral rigid structure, reducing excavation disturbance and improving structural rigidity. Water volume is adjusted through a large-diameter distribution valve.
It reduced the amount of excavation work, decreased the expansion of the loosened zone of the surrounding rock, improved the deformation resistance of the structure and the stability of the pump house, simplified the pipeline layout, and reduced the risk of leakage and maintenance difficulty.
