The camera monitors the condition in the well at any time, rainfall information can be collected by the rain gauge, the liquid level in the well can be measured by the liquid level meter, and the control system can perform intelligent management and control on equipment in the well according to information.

Take the example of a knife gate valve 23 at the cut-off end and a floating adjustable weir 24 and a hydraulic rotary weir gate 25 at the overflow partition. The knife gate valve is fixedly connected with the intercepting pipe through a bolt, so that the knife gate valve is installed and supported. The mounting bracket pipe of the floating adjustable weir 24 is connected with the reinforcing pipe, the first supporting rod and the second supporting rod through supporting rod fixing parts, so that the mounting and the supporting of the floating adjustable weir are realized. The mounting base of the hydraulic rotary weir gate 25 is fixedly connected with the overflow partition wall equipment wall through bolts, so that the mounting and supporting of the hydraulic rotary weir gate are realized.

In the early stage of sunny days or rainfall, when dry-run sewage or initial rainwater is discharged, the floating adjustable weir is completely opened, the hydraulic rotary weir gate is closed, and sewage enters a sewage intercepting pipe network or a regulating and storing tank from the water inlet end through the knife gate valve at the sewage intercepting end and finally enters a sewage treatment plant.

When the rain falls continuously, the flow of the water inlet pipe is increased, the liquid level of the water inlet end in the intercepting well rises, when the liquid level rises to the lowest point of the floating type adjustable weir equipment, the incoming water overflows to the water outlet end through the opened floating type adjustable weir, and finally the river is drained.

When rainfall intensity continuously increases, the liquid level of the water inlet end of the intercepting well rapidly rises, when the liquid level exceeds the set highest water blocking and storing level, the hydraulic rotary weir gate is opened, the incoming water can flood through the hydraulic rotary weir gate, the floating adjustable weir is automatically adjusted by utilizing self gravity and buoyancy according to the liquid levels of the water inlet end and the water outlet end, and finally the river is drained.

When the rainfall is finished, the liquid level of the water inlet end in the intercepting well is reduced, and when the liquid level of the water inlet end is lower than that of the water outlet end, the hydraulic rotary weir gate is closed; when the liquid level of the water outlet end reaches the bottom of the floating type adjustable weir device, the floating type adjustable weir rises along with the rise of the liquid level of the water outlet end, and the safety in the intercepting well is ensured.

When the intercepted sewage has no direction in a short time, the liquid level of the water inlet end in the intercepting well can be raised without overflowing by taking the pipe network as a temporary storage measure because the drawable overflow partition wall raises the overflow liquid level; if the liquid level at the water inlet end continuously rises, the water can overflow to the outer side through the opened floating type adjustable weir, and finally the water is discharged, so that the overflow amount and the overflow frequency are reduced, and the pollution of the outer river is reduced.

The integrated intercepting well provided by the embodiment realizes accurate interception, overflow pollution control, backflow prevention, no influence on flood discharge section and intelligent management and control by utilizing the intercepting equipment, the overflow equipment and the control system. The integrated structure can shorten the construction period, save the civil engineering cost and ensure that the integrated intercepting well can still be installed under severe working conditions. In addition, well lid, pull formula partition wall etc. optimize the pit shaft design, facilitate for follow-up fortune dimension.
