Description
Technical Field

[0002] The sludge drainage well is an indispensable facility in the water conveyance pipeline, mainly responsible for the collection and removal of sediments, and also supports the inspection and maintenance of the pipeline system. Currently, the sludge drainage well device for the water conveyance pipeline usually consists of a dry sludge well and a wet sludge well. A sludge drainage branch pipe is led out from the main water conveyance pipe, and the sludge drainage branch pipe is connected to a sludge drainage valve in the dry sludge well. The sludge drainage branch pipe behind the valve passes through the side wall of the dry sludge well and is connected to the wet sludge well, and a high-level drain pipe is arranged in the wet sludge well. When the water conveyance pipeline needs to drain sludge or drain water for maintenance, the sludge drainage valve in the dry sludge well is opened, and the water flows into the wet sludge well. The water in the wet sludge well flows by gravity through the high-level drain pipe into the nearby river or channel.

[0030] A sludge drainage branch pipe 5 is connected to the bottom of the valve well chamber 1 in a communicating manner. The sludge drainage branch pipe 5 is connected to the water conveyance main pipe 7 outside the valve well chamber 1 through a reducing tee 6; a sludge drainage valve 8 is installed on the sludge drainage branch pipe 5 inside the valve well chamber 1. The sludge drainage valve 8 is a manual gate valve, a manual butterfly valve, or a manual ball valve. The sludge drainage branch pipe 5 behind the sludge drainage valve 8 communicates with the energy dissipation chamber 2;
[0031] A layer of cobblestones 9 is laid at the bottom of the energy dissipation chamber 2. The particle size of the cobblestones 9 is 20 - 40 mm, and the laying thickness is 200 - 300 mm. The energy dissipation chamber 2 and the interception chamber 3 are arranged side by side and are connected by a partition wall 10. The top height of the partition wall 10 is 500 - 1000 mm lower than the top of the pool;
[0032] An interception grid 11 is horizontally placed in the middle of the interception chamber 3. The installation height of the interception grid 11 is 300 - 500 mm lower than the top of the partition wall 10; the grid gap of the interception grid 11 is 1 - 3 mm, and the material is carbon steel or stainless steel.
[0033] The interception chamber 3 and the outlet chamber 4 are arranged side by side, and a hole 12 is opened at the bottom of the connection part. The width of the hole 12 is the same as the width of the outlet chamber 4, and the height is 300 - 500 mm.

[0036] The utility model provides a sludge drainage well device for a water conveyance pipeline, and its working process is as follows:

When the water conveyance main pipe 7 needs to drain sludge or drain water for maintenance, the sludge drainage valve 8 in the valve well chamber 1 is opened, and the water in the water conveyance main pipe 7 enters the energy dissipation chamber 2 after passing through the sludge drainage valve 8.
