Side slope siphon drainage device with composite pipe diameter
The invention relates to the field of geotechnical engineering, and particularly relates to a side slope siphon drainage device with a composite pipe diameter. The drainage device comprises a drainagepipe and water injection equipment, wherein the drainage pipe is of a sleeve structure and comprises an external drainage outer pipe, a plurality of drainage inner pipes are arranged in the drainageouter pipe, and a water outlet of the drainage pipe is connected with the water injection equipment. The side slope siphon drainage device has the advantages that the hydraulic radius is increased, and the drainage efficiency is improved; and the installation times can be reduced by 4.7 times by using the composite pipe diameter under the condition that the same hydraulic radius is ensured, and the installation workload is greatly reduced.
本发明涉及岩土工程领域，尤其涉及一种复合管径的边坡虹吸排水装置。包括排水管和注水设备；排水管为套管结构，包括外部的排水外管，排水外管内设有多根排水内管；排水管出水口与注水设备相连。本发明一是增大了水力半径，提升了排水效率；二是在保证同样水力半径的情况下，使用复合管径可减少4.7倍的安装次数，较大幅度减轻了安装工作量。
