Description
Technical field
The present invention relates to environment functional material technical fields, and in particular to a kind of sand sill with fast drainage function
Preparation method.
Background technique
Fast drainage, seepy material have significant application value in the fields such as municipal administration, building, treatment of sewage.Such as in city
In the urban constructions such as city's road, square, quickly filter, the laying of porous pavement material are to placement road ponding, sponge city system
Building it is all significant.
Currently used rainwater on road surface seepy material mainly has concrete permeable material, ceramic water permeable material, polyphosphazene polymer
Close the compound filtering material of object seepy material, sand base seepy material and the above different materials.These existing seepy materials exist
Some shortcomings, if hole between concrete permeable material aggregate is larger, seepy material surface is easy to be blocked by dust and silt, causes
Water filtering performance decline；Ceramic water permeable material producing process is complicated, it usually needs sintering consumes mass energy, higher cost；High score
Sub- polymer seepy material, is generally made of one piece plastics punching, and drainability is poor, so that silt and rainwater are discharged into underground together
Pipe network；The water permeability of obvious above-mentioned current material is difficult to reach that simple production process, low energy consumption, high water-permeability and longer filter
The requirement of water timeliness needs to continue research and development and drainage and pervious function is constructed out while had by simple and easy method, and sexual valence compares
High composite material quickly filter for rainwater on road surface, is saturating etc. in urban engineering projects.
It filters, the mechanical performance of seepy material also has a major impact rigidity.In ancient building, ancients are just in the glutinous of sun-dried mud brick processed
Straw or reed etc. are added in soil to be modified clay, increase the pressure resistance of sun-dried mud brick using natural plant fibre therein
Degree.Have been reported that researcher prepares polymer fiber and modified concrete permeable material at present, polymer fiber used is usually
The high-molecular organic materials such as polypropylene fibre, polyacrylonitrile fibre and Fypro can be played by the way that polymer fiber is added
The effect for preventing concrete bracing, improving its shock resistance, fracture resistance.Organic polymer fiber also has preferable corrosion resistant
Corrosion and biggish toughness, but concrete permeable material carries out adhesion to sandstone aggregate mainly by cement (inorganic coagulation material),
Since all polarity such as polypropylene, polyethylene is smaller, when blending organic polymer fiber in concrete, cement and organic polymer
Fibrous binding force is weaker.Chinese patent application CN106186864A discloses a kind of novel polypropylene fiber concrete and its preparation
Method, polypropylene fibre used commonly use melt extruded, hot-rolling stretching, Surface Treatment with Plasma and addition coupling agent etc. before blending
