Transverse filtration drain pipe

Abstract

The invention discloses a transverse filtration drain pipe, and belongs to the technical field of foundation transverse drainage members. The existing structure or laying is complex, or the service life is short, and the drainage effect is poor. The transverse filtration drain pipe provided by the invention comprises a pipe body coated with a filter membrane, and is characterized in that the pipe body is divided into a perforated filter tube part and a solid wall part along the length direction; and the pipe body is made of plastic. The transverse filtration drain pipe provided by the invention has the advantages that the filter tube part and the solid wall part are arranged, thus a water storage space drainage channel can be preferably formed, the drainage effect is good, and the filter membrane has less possibility of being damaged; and the transverse filtration drain pipe is rust resistant, has a long service life, can be widely applied to various foundation treatment projects, is favorable for the reduction of construction period, has good resistance to pressure, and is light in weight, low in cost and convenient for transportation.

Description

【Technical field】 [0001] The invention relates to a horizontal filtering drainage pipe fitting, which belongs to the technical field of foundation horizontal drainage components. 【Background technique】 [0002] Ground treatment projects such as road green belts, building foundation excavation, landfills, tunnels, subways, culvert excavations, etc. often require drainage. In the prior art, permeable materials such as sand, gravel, and gravel are often used to coat the filter membrane to form a permeable pipe embedded in the surface or shallow layer of the foundation that needs to be treated, and then the impurities in the accumulated water are isolated through the filter membrane, and the pump is used to Drain the accumulated water entering the permeable pipe from the construction foundation. Because this kind of permeable pipe is inconvenient to carry, it basically depends on the fabrication and laying on the construction site, and it is laborious and troublesome to carry t...

AI Technical Summary

Problems solved by technology

Due to the inconvenient handling of this kind of permeable pipe, it basically depends on the construction site to make and lay, and it is laborious and troublesome to carry the permeable material, which affects the progress of the project

In addition, in recent years, there is also a prefabricated permeable pipe, which is made of a spring-shaped metal wire wrapped by a filter membrane, and can be laid directly on the construction site. However, in order to adapt to the complex water content of the foundation, the metal wire needs to be used Anti-corrosion materials must also meet certain compressive strength requirements, so the cost is relatively high. When the pressure on the pipe body is high, the filter membrane will be embedded in the gap between the metal wires and crushed, thus losing the filtering function; For projects with complex water quality such as landfills, the corrosion resistance of metal wires is not ideal, the life of the pipe body is short, and the drainage effect is poor

These two kinds of permeable pipes are permeable throughout the body, so the water that has entered the pipe body will seep back into the foundation, and the drainage efficiency is unstable.
