Description
Technical field
The present invention relates to bed mud in river processing, and in particular to a kind of solidification processing method of bed mud in river.
Background technology
From preceding, the problem of many rivers of China start to be faced with terms of bed mud dredges bold and vigorous desilting to be renovated.River dredging
One feature of the bed mud dug out is that moisture content is high, there is different degrees of pollutant, such as without dealing carefully with disposal, is had very much
Secondary pollution may be brought.Thus, it is necessary to properly settle a large amount of problem of outlet for dredging bold and vigorous bed mud.
The conventional disposal options of current river bed sludge mainly have stacking, and depression backfill, the betterment of land and ocean are thrown aside.
But above-mentioned various methods of disposal are all in the presence of occupation of land is excessive, disposal process is bothered, cost of transportation is high and may bring secondary dirt
Intercalation topic in terms of dye.
To dispose a large amount of River Muds, also a kind of processing method that sludge curing is blocking at present, after curing process
Cured block can be used as construction material, after sludge curing secondary pollution can be avoided to accomplish waste reclamation.
Under the conditions of current technology, after the solidification of river bed bed mud, cured block has the following disadvantages, causes cured block to be led in building
The application in domain is not quite varied.
(1) compression strength of cured block is not enough, only 10 MPas or so, can be used only in the building field of low-intensity demand；
(2) proportion of cured block is larger, with building so that the weight-bearing load of building is larger；
(3) cured block quality is more crisp, and plasticity and toughness are not enough, and cured block is anti-shearing and ability of flexure is poor.
(4) reach curing cycle 30 days or so, curing time is oversize.
The content of the invention
It is an object of the invention to provide a kind of solidification processing method of bed mud in river, in order to solve the above problems, this hair
Bright concrete scheme is as follows：A kind of processing method of bed mud in river, comprises the following steps：
(1) bed mud in river that the moisture content without dewater treatment is 90%~98% is taken, bed mud in river moisture content is not enough
90% add water is supplied, on the basis of the weight of bed mud in river, the coal-fired clinker of addition 2%~6%, 1%~3% into bed mud
Quick lime, 1%~3% gypsum, 0.3%~0.5% polypropylene fibre, form bed mud mixture after uniform mixing；
(2) on the basis of the weight for the bed mud mixture being made by step (1), the brick added in 2%~6% building waste
Block concrete chip, the cement for adding 8%~10%, addition cement blowing agent 0.3%~0.5%, uniform mixing form solidification
Precursor；
(3) solidification precursor is laid in the lew of ventilation with 5mm~30mm thickness, is covered and supported using covering
Shield, curing temperature is more than 0 degree Celsius；Avoid cured block and contact with moisture within 3 days before curing period；After maintenance 3 days, on covering
Water drenching, makes covering be in wetting state all the time 15 days, after 15 days moist curings, you can so that bed mud in river is thoroughly solid
Change.
It is preferred that, the size controlling of the fragment of brick concrete chip in above-mentioned step (2) is at 3~8 millimeters.
It is preferred that, above-mentioned cement uses alkaline cement；It is 25% that described cement blowing agent, which includes percentage by weight,
Sodium thiosulfate, percentage by weight is 57% lauryl sodium sulfate, and the aluminium powder that percentage by weight is 18%；Described
The grain fineness of aluminium powder is more than 800 mesh.
In the present invention, coal-fired clinker contains substantial amounts of silica, alundum (Al2O3), titanium dioxide three-iron, but dicalcium silicate,
The content of tricalcium silicate and tricalcium aluminate is less, under conditions of having quick lime and moisture, and lime reacts with water first, raw
Into calcium hydroxide；It is alkalescence in calcium hydroxide, under alkali-activated carbonatite effect and calcium ion contrapolarization, coal-fired clinker dissolution activity
Silica and active alundum (Al2O3), calcium hydroxide occur anti-with the active silica of dissolution and clean property alundum (Al2O3) again
Should, generation hydrated calcium silicate and drated calcium aluminate.Due to there is drated calcium aluminate generation, when master enters a certain amount of gypsum certainly, aquation
Calcium aluminate can be with gypsum reaction generation hydrated calcium aluminate sulfate.So the solidification of bed mud will be completed tentatively；Add such as 2% in cured block
~6% fragment of brick concrete chip is that backing material is skeleton, and polypropylene fibre is supporting material, and cement is binder materials, is made
The compression strength for obtaining cured block is greatly improved, and the compression strength of cured block is up to 20~30Mpa.
In use, when Crack failure occurs in cured block, due to the presence of polypropylene fibre, having delayed crack in cured block
Further development, therefore the axial pressure energy power that can bear of cured block is not in the phenomenon die-offed, and polypropylene fibre is deposited
The toughness of anti-shearing and warp resistance destruction is presented causing cured block.The tension that polypropylene fibre is undertaken is depended primarily on
The anchor force of frictional force and consolidated structures between fiber and cured block internal particle to fiber.Accordingly, it would be desirable to which fragment of brick is mixed
The size controlling of solidifying soil chip is increased at 3~8 millimeters with increasing the contact area of fragment of brick concrete chip and polypropylene fibre
Frictional force.The particle diameter of fragment of brick concrete chip also acts as the effect of support frame, therefore granularity can not be meticulous, crosses detailed rules and regulations support
Power is not enough, and size controlling is a suitable particle size range at 3~8 millimeters.
The presence of foaming agent so that be full of in cured block in bubble, cured block and cellular is presented, hole exists through magnitude range
Between 0.5~2.0mm, it is distributed than more uniform, mutual not insertion between Kong Jing.There is hardening mineral shape barrier film cut-off, form one kind
The cellular porous rock-steady structure of class, thus compression strength is further improved.Alkaline cement is used in preferred scheme, and
Alkalescence is supplemented using sodium thiosulfate, using lauryl sodium sulfate as surfactant, aluminium powder reacts in the basic conditions
Generate hydrogen formation bubble；The speed of reaction is controlled by the fineness of aluminium powder, and grain fineness can obtain suitable more than 800 mesh
Foamable reaction speed.
To sum up, advantages of the present invention have it is following some：
(1) compression strength of cured block is improved so that the application of cured block becomes wider；
(2) toughness of cured block is greatly enhanced, cured block is anti-shearing and flexural property is greatly enhanced；
(3) bubble is rich in cured block so that the proportion of cured block is greatly reduced, and will not excessively increase building when using
Weight-bearing load, and with alveolate cured block also have good heat insulating effect.
(4) curing time was at 18 days, and curing time is short.
