Environment-friendly recession port with silt filtering, anti-blocking and high-efficiency drainage functions

Abstract

The invention provides an environment-friendly recession port with silt filtering, anti-blocking and high-efficiency drainage functions. The recession port comprises a vertical shaft, a silt filtering water baffle, an anti-blocking vibrator, a drainage channel and a drainage sluice, wherein the vertical shaft consists of a vertical shaft foundation and a vertical shaft frame, and is arranged in a reclamation project area or a silt discharging field; the silt filtering water baffle is arranged on the vertical shaft frame; the anti-blocking vibrator is arranged on the silt filtering water baffle; one end of the drainage channel is connected with the bottom of the vertical shaft, and the other end of the drainage channel extends to a sluicing area outside the reclamation project area or the silt discharging field; the drainage sluice is arranged on the drainage channel. According to the recession port, the silt filtering water baffle is effectively prevented from being blocked by silt, the permeable rate of a geotextile is greatly increased, the sluicing capability is improved, and the concentration of suspended matters and the particle sizes of particles in a water body drained from the recession port are reduced, so that the size of the recession port is reduced to achieve multiple effects of economy, practicability and environment friendliness, and the recession port can be widely used as a hydraulic structure for the drainage of a hydraulic reclamation area and the tail water drainage and the like of the silt discharging field in dredging and desilting projects.

Description

technical field [0001] The invention relates to a device in the technical field of water conservancy engineering and water environment protection engineering, in particular to an environment-friendly water outlet with the functions of filter mud anti-clogging and high-efficiency drainage. Background technique [0002] Land reclamation is an important way to solve the shortage of land resources in our country. In the next ten years, my country will use dredging fill for tidal flat reclamation on a larger scale. In the construction of dredging and reclamation, the drainage system is a key work related to the safe and efficient operation of the reclamation area. Although the outlet (or tailgate) is only a temporary auxiliary facility for controlling tail water discharge in dredging and reclamation projects, it plays a direct regulatory role in improving the sedimentation effect in the reclamation area and reducing the pollution of mud to the environment. At present, the shaft...

AI Technical Summary

Problems solved by technology

Its main disadvantages are: 1) The control water level at the inlet cannot be adjusted with the progress of the reclamation project; 2) This method is not suitable for the discharge of tail water in the enclosing area of ​​land reclamation projects

Its main disadvantages are: 1) The control water level at the inlet cannot be adjusted with the progress of the dredging and filling project; 2) The inlet has no function of filtering sediment, and the muddy water is directly discharged outward, which not only causes some mud loss, but also pollutes the environment
