Background technology
The fast, economical development in China brings water conservancy, the climax of harbor approach engineering construction, in various river courses, navigation channel
During dredging and widening and harbour is newly-built, in extension project, is inevitably generated substantial amounts of waste silt.According to incomplete
Statistics, the mud that China discards every year reach several hundred million cubic meters：The wherein coastal area such as East Sea, Beihai Region generates a great deal of
Mud, while in order to river course be able to maintain that normal flood carrying capacity and ensure thoroughfare unimpeded, the dredging in inland river course
Amount of sludge is also considerable caused by quantities.Current most inland dredging silts are discarded in land throwing area or low
Depression area, some take original fish pond or cultivated land, and soil is valuable at present, and land expropriation cost is very high, such as south water to north east line
The funds of first phase land acquisition account for 60% or so of engineering total cost.
The main purpose of existing process for treating sludge is dehydration, and the process for treating sludge commonly used in engineering is using outer
Power extrudes mud internal moisture.Chinese patent CN101219297A discloses a kind of U-shaped soft vacuum dredged silt Quick drainage
Method, it is characterised in that multiple rows of U-shaped sand pocket is first set up on the ground of cofferdam, wherein the both ends of U-shaped sand pocket pass through the first water respectively
Horizontal longitudinal airway tube is connected with horizontal longitudinal drainage pipeline and even for flat transverse drain or the second horizontal cross drainpipe, water
Flat longitudinal drainage pipeline connects vacuum extractor, and horizontal longitudinal airway tube connection gas permeable devices form U-shaped space drainage system；Becoming silted up
During mud hydraulic reclamation between the hydraulic reclamation later stage, the ventilative valve of regulation is under low vacuum by drainage system to draw water, and ensure that draining is led to
Unimpeded, the promotion mud-water separation in road, the concentration of the raising mud of larger amplitude.This method produces negative pressure using vacuum extractor,
Mud-water separation can be promoted.But the equipment employed in this method and method can not carry out deep dehydration, place to mud
Mud water content after reason is high, and engineering properties is poor, compared with the mud after deep dehydration or can take larger stacking face
The problems such as product, hidden dangers in project is big, and overlapping development utilizes the cycle long.

Mud is dehydrated.
In this specific embodiment, the foundation ditch is mixed mud moulding by casting.So, convenient construction manufacture and intensity and just
Degree is high.
In this specific embodiment, the rectangular bodily form of mud placement space and foundation ditch.So, it is empty using rectangle
Between, the strong rammer of strong rammer device can be facilitated to hammer into shape it is matched.
When carrying out sludge treatment using above-mentioned device for treating sludge, following processing method can also be specifically used：A, first
The special agent being formulated as follows is obtained, the composition and quality proportioning of the special agent are 120 ~ 300 parts of cement, quick lime
0.02 ~ 0.1 part of 250 ~ 500 parts, 0.5 ~ 3.0 part of aluminium powder, 3 ~ 6 parts of water reducer, 5 ~ 10 parts of accelerator and foam stabilizer；B, it will treat
The mud of processing is inserted in device for treating sludge, then special agent is added in mud, then mud and special agent are stirred
It is even；C, after mud and special agent fully react, recycle strong rammer device to carry out strong rammer operation to mud, moisture is expressed into
Device for treating sludge is located at the ponding space on periphery and extracted out；D, by the mud after the completion of dewater treatment from device for treating sludge
Device external is transferred to, then carries out next subjob.
In the technical program, device for treating sludge is used in combination with strong rammer device and special agent, can realize by
Mud internal moisture is quickly discharged and the dehydrating effect of depth.First mud is inserted in device for treating sludge, now, inside mud
Water first pass through coarse sands layer from top to bottom, then the bottom surface for having acclive foundation ditch is arrived at after metalling, water is by introversion afterwards
Surrounding is then exhausted from successively by entering ponding space after geotextile layer, drain bar, porous screed.Mud is carried out again afterwards
Deep dehydration, add special agent, wherein, the cement in special agent can reduce mud hydrophily, the hard fragility of increase mud,
Improve mud intensity；Quick lime can reduce mud hydrophily, the hard fragility of increase mud, improve mud intensity, disinfection, drop
The contaminative of low mud；Aluminium powder can foam mud, mud hardening when produce a large amount of bubbles, form the hole largely connected,
Fag end passage is formed, increases mud permeability；Water reducer can increase mud moisture surface activity, reagent is more easy to and mud
Mix；Accelerator can accelerate hardening of cement speed, rapid curing mud, effectively shorten the sludge dewatering time.
The special agent of addition enables to produce a large amount of holes inside mud, and quick-hardening, brittle property increase, simultaneously
Hydrophily weakens, hydrophobicity enhancing.Mud is hit when can facilitate strong rammer operation by the physics and chemical property that change mud
Broken, bubbles burst during strong rammer inside mud can form a large amount of transverse cracks and form drainage channel in the horizontal direction, together
When very big excess pore water pressure is internally formed in mud so that mud internal moisture flows to the inner side of device for treating sludge
Wall.So as to reach the dehydrating effect for realizing fast dewatering and depth.
Wherein, in step a, the best in quality proportioning of special agent is 260 parts of cement, 420 parts of quick lime, aluminium powder 1.8
Part, 5.6 parts of water reducer, 7.8 parts of accelerator and 0.08 part of foam stabilizer.
So, the effect of enabling to each component to give play to maximum using the special agent of optimum proportioning, each component it
Between influence each other it is smaller.
