Reverse osmosis water purifier

Abstract

The invention relates to the technical field of accumulated water drainage, in particular to a reverse osmosis water purifier. The reverse osmosis water purifier comprises a drainage pipe and a splitter plate, wherein the length of the splitter plate is matched with that of the drainage pipe, the splitter plate is horizontally arranged in the drainage pipe, the two ends of the splitter plate are connected with the inner wall of the drainage pipe, and an inner cavity of the drainage pipe is divided into an upper drainage cavity and a lower water accumulation cavity by the splitter plate; a plurality of first filtering holes are uniformly formed in the splitter plate; a plurality of second filtering holes are uniformly formed in the pipe wall of the lower water accumulation cavity; a first sealing plate is arranged at one end of the drainage pipe; and a second sealing plate is arranged at the other end of the drainage pipe, and a water outlet which corresponds to the upper drainage cavity is formed in the second sealing plate. Accumulated water can be effectively drained, additionally, wall collapse caused by hollowing out silt is prevented, and the drainage stability and the use stability of a retaining wall are improved.

Description

technical field [0001] The invention relates to the technical field of accumulated water discharge, and more specifically, to a reverse osmosis water filter. Background technique [0002] Retaining wall is a common form of slope protection, which is widely used in engineering because of its simple structure, convenient construction and good stability. As we all know, groundwater and surface water are an important factor affecting the stability of the retaining wall. In order to increase the stability of the retaining wall, the retaining wall should be equipped with good drainage facilities to drain the water in the soil behind the wall and prevent the ground Underwater seepage causes water to build up hydrostatic pressure behind the wall. At present, the most commonly used drainage method is to set up a drain on the retaining wall. PVC pipes or bamboo sticks are often used to reserve the drain, and some gravel is backfilled at the drain to filter the sediment in the accumul...

Problems solved by technology

[0003] Although this method is simple and easy to implement, when gravel or porous concrete blocks are filled at the outlet as the water filter layer, the water filter layer is easily blocked, resulting in the inability to discharge the stagnant water, or rats digging up the gravel to cause filtration When the water layer is destroyed, it will be discharged together with mud and sand during drainage, and the hollowed out mud and sand will cause wall collapse, landslides, etc. At the same time, the outlet pipe is easily corroded and has a short service life

[0004] Similarly, traditional farming uses open channel irrigation, but open channel irrigation needs to dig pits and ditches on the land surface, which is not conducive to large-scale farming. Therefore, buried pipelines are improved for irrigation. There are drainage problems in retaining walls, and farmland irrigation is not good for crops. Had the same problem when replenishing water
