Water-absorbing fiber percolation pipe and dewatering device

Abstract

The invention provides a water-absorbing fiber percolation pipe and a dewatering device comprising the same. The water-absorbing fiber percolation pipe comprises at least one water guide pipes and a water-absorbing fiber sleeve. The water guide pipes are mounted in the water-absorbing fiber sleeve in a sleeved manner. The inside of each water guide pipe is separated by at least one grating to form a plurality of axial through water flow passages. Axial through grooves are formed in the water guide pipe walls corresponding to the water flow passages and communicated with the corresponding water flow passages. The water-absorbing fiber percolation pipe and the dewatering device have the advantages of remarkable dewatering effect, long service life and low production and utilization cost.

Description

technical field [0001] The invention relates to a drainage facility, in particular to a water-absorbing fiber seepage pipe and a drainage device with the water-absorbing fiber seepage pipe, which can be applied to various railway subgrades, highway subgrades, geotechnical engineering, greening engineering, playground drainage, and saline-alkali land treatment , tunnel engineering waterproofing and drainage and other water collection pipes, as well as projects such as urban rainwater infiltration, etc., can save a lot of sand and stone grading or even omit sand and stone grading, reducing project cost. Background technique [0002] At present, in various engineering constructions, the treatment of waterproofing and drainage has been paid more and more attention by people. Especially in railway embankment projects, the soil of the embankment is often liquefied by rain, snow, and groundwater under the vibration of the train, resulting in slush, mud, and subsidence of the roadbe...
