Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of road drainage, and specifically relates to a spliced road drainage prefabricated part and a spliced road drainage system. BACKGROUND

[0002] Collapsible loess refers to soil that has significant additional deformation due to structural damage after being soaked under the action of overburden stress or the combined action of overburden stress and additional stress, and belongs to special soil. Some miscellaneous fill also has collapsibility. Collapsible loess is widely distributed in northeast China, northwest China, central China and part of east China. Collapsible loess changes in structure when it encounters water, and causes extremely serious damage to sites and roads in engineering construction. Preventing water seepage becomes an important content in engineering construction.

[0003] The current concrete road rain drainage system has two kinds, namely, open ditch drainage and buried pipe drainage. Rainwater on the road is collected by the road into an open ditch or a buried pipe at the roadside, and is discharged by the open ditch or the buried pipe, which can meet the drainage requirement to a certain extent, but cannot eliminate the seepage risk. When applied in collapsible loess areas, the risk of structural damage is easy to occur. Specifically, the reasons for the existing concrete road drainage system to easily produce seepage mainly include two points: (1) the open ditch, the buried pipe and the road are all cast-in-place concrete structures, and cracks are inevitably produced due to temperature changes, stress shrinkage, material quality, construction quality, chemical corrosion and traffic load, etc., resulting in seepage; (2) too many on-site interfaces and joints, unevenly tamped construction filling, extrusion and vibration from the outside world, chemical corrosion, etc. cause seepage. In addition, the existing road drainage system also has the following disadvantages: (1) the open ditch or the buried pipe is on one side or both sides of the road, which needs to occupy additional land; (2) the on-site construction condition is poor, the construction quality is difficult to guarantee, and the construction standard is difficult to unify. SUMMARY

[0004] Therefore, the utility model aims to provide a spliced road drainage prefabricated part and a spliced road drainage system, which can effectively reduce the seepage risk and can be applied in collapsible loess areas.
