Description
Technical field
The present invention relates to technical field of building construction more particularly to a kind of earthwork composite material filtering guide structure and productions
Technique.
Background technique
Water is an important factor for influencing pavement structure, road foundation self-strength and stability, and principal mode is ground
Table water and underground water.In southern rainy regions, the harm of surface water is mainly reflected in souring and precipitation to roadbed
It penetrates into and generates delay in subgrade soil, cause subgrade soil interior moisture content excessively high, reduce the load-carrying properties of roadbed.Separately
Outside, the presence of underground water is totally unfavorable to the stability of road structure, when especially water level is excessively high, can draw in capillary water uphill process
The differential settlement for playing roadbed, to destroy superstructure.
It may be due to construction using natural sand or gravel adrainage material or material is unstable will cause certain ask
Topic, and required project amount is very big, side slope be more than the local material of certain angle laying just at very big problem, while sand
Exploitation with gravel also will cause very big environmental disruption.
Have at present and drained using TGXG, such as infiltration disclosed in Patent No. CN101487236B drains building
Grid forms reticular structure through connection by the hollow drainage pipe with water seepage hole, it is adjacent by having water seepage hole flexible water drainage pipe
Drainpipe multiple spot connects and composes infiltration drainage grill through mechanical sequential, it is characterized in that the drainpipe for constituting grid is flexible, two-phase
Adjacent drainpipe intercommunication constitutes grid.But drainage effect is poor.
It is drained later and gradually using drainage network, such as a kind of cloth composite drainage network disclosed in CN203403399U,
By the way that the improvement on draining web frame, to improve the problem of easily depositing, blocking, but the service life of drainage network is undesirable,
It is poor to the endurance of high pressure load.
Summary of the invention
The present invention provides a kind of earthwork composite material filtering guide structure, can resist aging, rot, service life is prolonged
It is long, and there is very strong tensile strength and resistance to compression.
A kind of earthwork composite material filtering guide structure, including providing the support base of rigid support, being arranged in the branch
