An underground logistics transportation pipeline

Abstract

The invention relates to an underground logistics transportation pipeline. The underground logistics transportation pipeline comprises support columns, a connecting plate, a composite bedding layer, alower bearing plate, a pipe core, waterproof plates, side protecting plates, anti-settling rods, an upper bearing plate and waterproof geotextile, wherein the support columns are arranged on a bearing layer of a soil body; the connecting plate is arranged at the top parts of the support columns; the composite bedding layer, the lower bearing plate and the pipe core are sequentially arranged on the connecting plate; the waterproof plates are arranged at both sides of the pipe core; the side protecting plate is arranged at one side of each waterproof plate; each anti-settling rod is arranged atone side of each side protecting plate; the upper bearing plate is arranged at the top parts of the pipe core, the waterproof plates and the side protecting plates; the waterproof geotextile is arranged on the upper bearing plate; the composite bedding layer consists of a lower bedding layer, a geogrid and an upper sealing layer from bottom to top. The underground logistics transportation pipeline has the advantages that the nonuniform settlement of the pipeline due to scouring by underground water flow and self-weight load is effectively relieved, the service life of the pipeline is guaranteed, one pipeline can simultaneously adopt multiple transportation modes, the transportation efficiency is greatly improved, and the underground logistics transportation pipeline is suitable for beingpopularized in larger range.

Description

technical field [0001] The invention belongs to the technical field of logistics transportation devices, in particular to an underground logistics transportation pipeline. Background technique [0002] At present, the continuous popularization of online shopping has made the logistics and transportation industry develop rapidly. The logistics transportation with ground vehicles as the main method has been unable to meet the rapid growth of cargo transportation, and vehicle transportation has also aggravated traffic congestion and air pollution. Pipeline transportation has the characteristics of less land occupation, low investment, short construction period, low operating cost, low energy consumption, safety and reliability, etc. However, there are many problems in the pipeline used for logistics transportation, which are summarized as follows: [0003] 1. Uneven settlement of the pipeline: Under the action of groundwater flow and pipeline self-weight load, the foundation u...

AI Technical Summary

Problems solved by technology

[0004] 2. The erosion and damage of the pipeline structure by groundwater; when the pipeline is partially or completely underground, the groundwater will gradually erode the pipeline structure, which will seriously reduce the bearing capacity and service life of the pipeline structure under long-term effects

[0005] 3. The damage of the upper load to the pipeline; when the pipeline is completely underground, the long-term effects of factors such as the backfill on the upper part of the pipeline and the driving load will cause damage to the upper structure of the pipeline. If no protective measures are taken, the service life of the pipeline will be seriously affected

[0006] 4. At present, when pipelines are used for logistics transportation, most of them use rail cars or special vehicles for transportation. One pipeline can only use one transportation method at the same time, resulting in low transportation efficiency
