Description
Technical field
The invention belongs to drainage system technical field, more particularly, to rich water cutting combined type arrange drop ground water regime and its
Construction method.
Background technique
In the use process of road, influence of the water to the service life of road is very big.If the cutting around road produces
Raw ponding can not effectively be discharged, and will be unable to estimate on influence caused by road.Water in cutting can be gradually to cutting two
The side slope of side and downwards infiltration are deteriorated will lead to the soil property around cutting.It is in particular in the water content of surrounding soil significantly
Increase, the hole inside soil is caused to become more.If in addition the fine grained soil of the soil around the cutting is more, the infiltration of moisture will
These fine grained soils can be taken away, also result in that hole in soil increases, water content increases, eventually lead to road foundation softening, give
Surrounding soil leaves security risk.If the soil of roadbed is special soils, the infiltration of water will be bigger to the harm of roadbed.Such as:
For collapsible loess in no contact water, its intensity is higher, and compressibility is smaller, and can sink rapidly if it meets water, native
It is destructurized；If subgrade soils are swelled ground, and swelled ground has water swelling, the characteristic of dehydration shrinkage, if therefore water
The disasters such as crack, roadbed shakiness will be will cause by penetrating into swelled ground；And if salinized soil, it, which has, meets water-soluble sunken characteristic, because
This can not allow moisture penetration to enter.In addition the vehicles on road are in driving process repeatedly, will generate one repeatedly
Dynamic stress, ponding cutting is in dynamic stress coverage, it will causes the durability of road to be affected, eventually leads to road production
Raw unstability disaster.
Therefore, it needs to seek a kind of cutting discharge structure and its construction party Faxian effective, stability, durability are good at present
It obtains particularly significant.
