Description
Technical field
The invention belongs to mud dehydration plant, particularly a kind of hydraulic type soil engineering bag dewatering box device with hydraulic pressure function.
Background technology
Along with development that is social and economic level, the requirement of people to inhabitation and surrounding enviroment is more and more higher, the comprehensive regulation of the water body such as river course, lake is more and more frequent, the mud cleaned out because of improvement is mostly containing certain pollutent, and the scale of construction is huge because water ratio is high, often reach tens sides or hundreds of all places.How so a large amount of mud carries out the great difficult problem that follow-up treatment and disposal is the comprehensive regulations such as current river course, water body, much more general adopt that airing is air-dry carries out pre-treatment, fill for roadbed or foundation ditch afterwards, make building materials, agricultural use, landfill etc.But because mud water ratio is higher, mud to be transported and subsequent disposal is disposed and added great difficulty, therefore, make full use of that to carry out after field condition completes dehydration decrement that subsequent disposal disposes again be the measure extensively adopted.At the scene in dewatering, soil engineering bag is permeable, and because having, treatment capacity is large, low price, simple to operate, field condition can be made full use of complete the advantages such as process and be widely used.But when adopting existing soil engineering bag to dewater, deviate from moisture lack collection and focus on, be generally utilize field condition to flow back to water body, easily pollute, and utilize naturally osmotic and mud self gravitation to complete extrusion dehydration during dehydration more, squeezing effect is not good enough, and dewatering efficiency is on the low side, and the time is longer, and when adopting earth or stone to carry out counterweight extruding, because mud amount is huge, dewatering bag volume is bigger than normal, there is the difficulty on execute-in-place.
In view of the above problems, need to innovate original soil engineering bag dehydration technique, gravity extruding problem should being solved, strengthening the purification to deviating from moisture again, operation be wanted simple, possess the feasibility in desilting site work simultaneously.
Summary of the invention
The present invention proposes a kind of hydraulic type soil engineering bag dewatering box, be made up of dewatering box, dewatering bag, hydraulic pressure bag, water pump and connecting pipeline etc.Be provided with support or dividing plate bottom dewatering box, for supporting the weight of dewatering bag and hydraulic pressure bag, and collect in dewatering bag and deviate from moisture; Dewatering bag is that geotextile makes, and has permeable effect, is positioned on the porous support in dewatering box, for separating of matter dry in mud and moisture; Hydraulic pressure bag is that impermeable film is made, and utilizes own wt to extrude the dewatering bag of bottom after water filling; Water pump and connecting pipeline are used for injecting hydraulic pressure bag by deviating from moisture in dewatering bag.
A kind of hydraulic type soil engineering bag dewatering box; Form infiltration pond 13 between the platform support that dewatering box 1 bottom is arranged or dividing plate, dewatering bag 2 horizontal is on platform support 6 or dividing plate 7, and hydraulic pressure bag 3 horizontal is on dewatering bag; Dewatering bag is provided with note mud mouth 5, hydraulic pressure bag is provided with water filling port, pond 13 is provided with water outlet in infiltration, is connected between the water filling port 11 and the water outlet 10 in infiltration pond 13 of hydraulic pressure bag by pipeline with water pump 4.
The dewatering box that the present invention proposes is applicable to the dehydration operation of extensive mud in river course or water body desilting site, is inconvenient to use other ballast modes such as earth or stone to dewater in operation.Its working process is placed in by dewatering box on smooth and comparatively strong ground or platform, bottom installs support or dividing plate, afterwards by dewatering bag horizontal on support or dividing plate, again hydraulic pressure bag is flat on dewatering bag, then connect the mud injection pipe road of dewatering bag, and tank bottom dewatering box and hydraulic pressure bag are coupled together by pipeline and water pump.As need medicament be added, also need to access Assistant pipeline on mud injection pipe road, water pump rear end pipeline accesses Water purification medicament pipeline.During work, first in mud injection pipe road direction dewatering bag, inject mud to be drained off, moisture is constantly had to deviate to enter in the tank of dewatering box bottom in filling process, start water pump and this part is deviate from moisture injection hydraulic pressure bag, utilize the weight of water to continue extruding dewatering bag below, and then effectively improve dewatering efficiency.Moisture in hydraulic pressure bag forms precipitation purification because leaving standstill to act on completing, and having, effect under water purification agent effect is better.To be drained off complete after by hydraulic pressure bag moisture discharge, remove pipeline, remove hydraulic pressure bag, cleaning dewatering box in mud cake, complete dehydration.
In equipment proposed by the invention, dewatering box is uncovered casing, can be steel, concrete system, wooden or engineering plastics are made, bottom is provided with support or dividing plate, for supporting dewatering bag and ensureing that moisture passes through, dewatering box bottom also should be provided with tank, for collecting moisture.Dewatering bag is made by geotextile, can be individual layer or bilayer formation, and time double-deck, skin is high strength cloth, and internal layer is fabric or the non-woven fabrics of hypertonicity.Hydraulic pressure bag is made by impermeable film material, has watertightness.
Dehydration equipment proposed by the invention operationally, can add Assistant before mud injects dewatering bag, and can be molysite or aluminium salt and polymkeric substance thereof, also can be the organic polymers such as polyacrylamide.Assistant add the cohesion that can realize particulate matter in mud, its particle is increased, can effectively improve dewatering speed and dehydration rate.
Deviate from purifying water of moisture for improving, also can add Water purification medicament before discharge water is injected hydraulic pressure bag by water pump, its composition can adopt molysite or aluminium salt and polymkeric substance etc. thereof.Water purification medicament can realize fine particle and coacervation of colloid in water by cohesion and become large, and be conducive to particulate matter completes sedimentation in hydraulic pressure bag, and then improves the water quality getting rid of water.
The present invention proposes a kind of hydraulic type soil engineering bag dewatering box device, dehydration can be completed at water body desilting site, can effectively solve mud water ratio high and cause transport and follow-up disposal difficulties.The present invention utilizes the effect of dehydration casing and the function intensified soil engineering bag dehydration of hydraulic pressure, sets forth device structure and dewatering work process.Utilize this method and equipment can effectively improve soil engineering bag dewatering efficiency, shorten the operating time, and can effectively improve the water quality of deviating from moisture, reduce secondary pollution.This equipment also can be used for sewage sludge, construction slurry, bean dregs and unclassified stores dehydration etc.
