Problems solved by technology

[0003] The existing water supply and drainage equipment for water conservancy construction mainly has the following shortcomings: when the water pump pumps out the water flow under the foundation, the water flow carries gravel, and when it is discharged, because the drainage groove is in the shape of a cone, the gravel is in the water. Under the impact of the impact, it is stuck in the drainage groove, causing the drainage groove to be congested by the accumulation of gravel, causing the flow rate of the drainage groove to become smaller when draining

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to water supply and drainage equipment for water conservancy construction. Background technique [0002] Water conservancy project is a kind of engineering facility used to allocate and control water resources. When building a dam of a water conservancy project, it is necessary to drain the water in the foundation hole through water supply and drainage equipment, and then construct steel bars and concrete to make it The foundation can be fixedly supported for water storage control and management. [0003] The existing water supply and drainage equipment for water conservancy construction mainly has the following shortcomings: when the water pump pumps out the water flow under the foundation, the water flow carries gravel, and when it is discharged, because the drainage groove is in the shape of a cone, the gravel is in the water. Under the impact of the impact, it is press...
