Water collection and water logging drainage system and construction method thereof

Abstract

The invention discloses a water collection and water logging drainage system and a construction method thereof. The system comprises a drainage ditch, a drainage shaft, a drainage pipe and a water collection channel, wherein the drainage shaft is connected with the drainage ditch and the drainage pipe, the water collection channel is connected with the drainage ditch, and a plurality of water logging drainage guide pipes with different lengths are arranged on the drainage shaft, the water logging drainage shaft comprises a no-sand concrete pipe, a geotextile filter screen and a water filtering net cushion, the geotextile filter screen wraps the outside of the no-sand concrete pipe, the water filtering net cushion wraps the outside of the geotextile filter screen, and the water logging drainage guide pipes are perpendicular to the no-sand concrete pipe and communicate with the no-sand concrete pipe. The method comprises steps as follows: embedding of a drainage pipe, laying of a filter material, arrangement of the water logging drainage guide pipes, arrangement of the water collection channel, arrangement of a sand blocking ridge, arrangement of grids, mounting of the no-sand concrete pipe and wrapping of the water filtering net cushion. The problems about water logging drainage and flood drainage can be effectively solved, and the long-term effective water logging drainage and flood drainage effects are realized.

Description

technical field [0001] The invention belongs to the technical field of drainage in water conservancy and hydropower projects, and in particular relates to a water collection and drainage system and a construction method thereof. Background technique [0002] After the embankment of the urban protection area is built, the area where the anti-seepage wall is set at the foundation of the embankment blocks the channel for the original groundwater in the protection area to flow into the river outside the defense area, so the groundwater level in the protection area will be raised, causing submergence. At present, in order to reduce the permanent land occupation of the project, sand-free concrete pipes are generally buried behind the embankment to reduce the groundwater level and surface water in the submerged area, and the groundwater and surface water are led to the drainage stations in various protection areas through sand-free concrete pipes . However, the currently commonly ...

AI Technical Summary

Problems solved by technology

However, this structure often cannot achieve a good drainage effect during the flood season when groundwater is abundant, and the single drainage pipe structure also has limitations on the surface drainage effect, which cannot meet the drainage requirements of surface water
