Abstract
The invention relates to a harbor construction sea reclaimed material utilizing silt, which is prepared by mixing gangue sand, the silt and cement. Water content of the silt is 60%-100%, and the weight ratio of the silt, the gangue sand and the cement is 1: 3-5: 0.04-0.06. A preparation method of the harbor construction sea reclaimed material utilizing silt is further disclosed. The material and the method achieve waste object utilization of the gangue sand and the silt. The material is high in strength, low in construction cost and capable of achieving quick solidification of silt and saving a large amount of natural resources. The material can be applied to projects such as sand quilt blowing filling, filtering guide layers, sand cushion layers and land area backfilling.
Description
Technical field
The present invention relates to the port engineering New Building Materials, particularly a kind of port construction material reclamation that utilizes mud; The invention still further relates to a kind of preparation method of above-mentioned material reclamation.
Background technology
The port engineering construction needs a large amount of sandstone material resources, and with environment protection, sandstone material resource day is becoming tight, and has seriously restricted port construction speed and quality.Port construction need be excavated a large amount of mud, is to be poured on the off-lying sea to mud in the past, causes waste and pollution.Because sludge granules is thin, water cut is high, mechanics index of physics is poor, in the port construction, must handle mud, mud is excavated, and hydraulic reclamation epeirogenetic, use as ground behind the employing discharging consolidation.The discharging consolidation of mud vacuum preloading commonly used and piling prepressing technology and technology, but all need a large amount of backfilling materials, comprise working cushion layer, sand bedding course, resist and ballast layer, all need a great amount of building material, particularly sand.But sandstone material resource is at full stretch recently.Therefore we seek new equivalent material and seem and be even more important.
Mine tailing sand is the waste behind the various ore extracting effective componentss, and pile up like a mountain throughout the year, takies a large amount of soils, and surrounding environment is caused very big pollution, up to the present, does not still have perfect processing, utilizes way.
Summary of the invention
The technical problem that the present invention will solve is the deficiency to prior art, has proposed that a kind of formula prepared is reasonable, result of use good and can effectively utilize the port construction material reclamation that mud of rejected material.
Another technical problem to be solved by this invention has provided the above-mentioned preparation method who utilizes the port construction material reclamation of mud.
Technical problem to be solved by this invention is to realize through following technical scheme.The present invention is a kind of port construction material reclamation that utilizes mud, is characterized in that it is processed by CHARACTERISTICS OF TAILINGS SAND, mud and cement mixing, and the water cut of said mud is 60-100%, and the weight ratio of mud, CHARACTERISTICS OF TAILINGS SAND and cement is 1:3-5:0.04-0.06.
In the above-described port construction material reclamation technical scheme of utilizing mud: the weight ratio of mud, CHARACTERISTICS OF TAILINGS SAND and cement is preferably 1:4:0.05.
Technical problem to be solved by this invention can also further realize through following technical scheme.The invention also discloses a kind of as the described preparation method who utilizes the port construction material reclamation of mud of above technical scheme, be characterized in that its step is following:
(1) blowing-filling sludge is grasped and store up to its water cut be 60-100%;
(2) in mud, add CHARACTERISTICS OF TAILINGS SAND and cement by said part by weight, stir mixture;
(3) adopt high-pressure delivery pump that mixture is filled in mould bag or the filling material, get final product.
CHARACTERISTICS OF TAILINGS SAND of the present invention can be the waste behind the various ore extracting effective componentss, is generally particulate state.
Compared with present technology, advantage of the present invention and technique effect are:
1, the present invention can realize the utilization of waste material that mine tailing is husky: the port construction fast development; Technology of the present invention can use mine tailing husky in a large number; Not only solve the husky problem of outlet of mine tailing, solved environmental issue, also saved the natural resource of a large amount of sandstone material material of construction.Material of the present invention can be applied to husky by hydraulic reclamation, lead in the engineerings such as filtering layer, sand bedding course, land-based area backfill.
2, the present invention can realize the utilization of waste material of mud: in the port construction, need excavate a large amount of mud.The present invention can use mud in a large number, has solved the problem of outlet of mud, and also having accomplished turns waste into wealth.
3, the intensity of material of the present invention is high, and its mechanical index can reach cohesion 34, and internal friction angle 27 degree are far above the comprehensive mechanics index of physics of general sand bedding course.Small amounts of contamination in the mine tailing sand has been reached environmental requirement by silt consolidation.The sea is gone in the pollutant emission of not finding to exceed standard.
4, material cost of the present invention is low, and mine tailing sand belongs to cheap material, and mud also is refuse, uses these materials, can reduce construction costs greatly.
5, material of the present invention can be realized the rapidly solidified of mud, and mud mixes with mine tailing is husky, and after the admixture small amount of cement, mud is realized rapidly solidified, and mud has become the husky gelling material of mine tailing, has improved the intensity of compaction material.When mine tailing sand used as permeable sand bedding course, because its space is big, PQ was high, so drainage speed is fast, was the sand mat of subgrade of good silt consolidation.
6, a large amount of natural resource have been saved in the application of material of the present invention.
