A kind of textile fabric filter layer coating device and using method thereof

Abstract

The invention relates to the technical field of underground buried pipe drainage, in particular to a woven fabric coating device and a using method thereof. The woven fabric coating device comprises a first support, a second support and a third support which are disposed on a base plane, a reel-type drainage buried pipe is arranged on the first support, a sleeve used for containing the reel-type drainage buried pipe is arranged on the second support, a reel-type woven fabric sleeve used for coating the sleeve is arranged on the third support, the second support is arranged closely to the reel-type drainage buried pipe and movably connected with the sleeve through a sleeve locking device, one end, close to the reel-type woven fabric sleeve, of the sleeve can be made to contact with the base plane, and a sleeve balance fixing device is arranged at one end, close to the reel-type drainage buried pipe, of the sleeve. The woven fabric coating device is high in filter material pre-coating speed, uniform in filter material pre-coating and capable of preventing fabric filter materials from being damage, so that drainage buried pipe filter material pre-coating efficiency and quality are improved.

Description

technical field [0001] The invention relates to the technical field of underground underground pipe drainage, in particular to a textile fabric filter layer coating device and a use method thereof. Background technique [0002] In order to effectively eliminate waterlogging in farmland or prevent soil salinization and provide a suitable growth environment for crops, it is necessary to take farmland drainage measures to control groundwater levels. Farmland underground pipe drainage technology is land drainage, prevention of salinization of irrigated land, transformation Effective measures for low-yield fields. [0003] Modern underground drainage pipes mostly use flexible plastic corrugated pipes, and uniform small holes are arranged on the pipe walls to facilitate the accumulation of water in the soil into the drainage pipes. In order to prevent soil particles from entering the underground drainage pipe and causing silting, it is usually necessary to lay a permeable and san...

AI Technical Summary

Problems solved by technology

In order to prevent soil particles from entering the underground drainage pipe and causing silting, it is usually necessary to lay a permeable and sand-proof filter layer (outsourced filter material) outside the hidden pipe to prevent silting. Although the traditional gravel filter material has good reverse filtration performance, However, due to the difficulty of obtaining raw materials or inconvenient transportation, the price is high, and it is not easy to construct

In recent years, the non-woven fabric filter layer has become more and more widely used, that is, the non-woven fabric is wrapped outside the drain pipe and fixed by winding to form a pre-wrapped filter layer, or the non-woven fabric is first sewn into a sleeve, and then manually The sleeve is placed on the drain pipe to form a pre-coated filter layer. Although the operation of the sleeve-type pre-coated filter layer is relatively simpler than that of the wound pre-coated filter layer, due to the large length of the drain pipe, it is generally tens of meters to hundreds of meters. In addition, the wall of the drain pipe is corrugated and not smooth, which leads to labor-intensive and time-consuming manual operation, difficult operation, low efficiency, and it is difficult to ensure the uniformity of the fabric filter layer, and even damage and other problems
