Abstract
The key technology that traditional mucky soil filling bag embankment needs solve is: one is the draining seepage paths shortening silt soil in bag, accelerates drainage rates, and two is that filling earth bag needs to increase build-in measure between layers.It is short that the technical program has bag draining seepage paths, band drain can effectively discharge many She moisture content in bag, bag and bag between because the fissure of displacement arranges mutual build-in, different laying methods can meet the different using function of dykes and dams, adopts special charging arrangement prodigiosin to meet the demand of construction.The technical program has started the new approach of mucky soil filling bag embankment; have broad application prospects in riverine, coastal land reclamation embankment and dam construction; compared with existing sand filling bag fill; cost can save more than 20%, and opens up a Tiao Xin road for riverine, coastal ecological environmental protection.
Description
Technical field
The present invention relates to mucky soil filling bag embankment method
Background technology
In the existing design of land reclamation embankment, in construction technology, mucky soil filling bag embankment is the focus technology received much concern in land reclamation engineering field always, along with the active demand of industrial land, create the develop rapidly of coastal land reclamation industry, but owing to being subject to coastal sand, the restriction of the day by day deficient and ecological environmental protection of stone resource, traditional sand filling bag fill faces very large predicament, and it is riverine, the mucky soil that Coastal beach widely distributes can be used for filling bag embankment be always land reclamation industry try hard to for many years develop an important technology.
The general particle of mucky soil is comparatively thin, water content is higher, and longer between discharging consolidation after the fill of filling earth bag, filling earth bag easily slides between layers, and difficulty of construction is larger.
The key technology that traditional filling earth bag fill needs solve is: one is the draining seepage paths shortening mucky soil in bag, accelerate drainage rates, two is that filling earth bag increases build-in measure between layers, prevents bag from causing the slip between bag in the construction period because of the non-consolidation of mud.
Summary of the invention:
The technical issues that need to address of the present invention are to provide a kind of mucky soil filling bag embankment method, solve existing mucky soil filling bag embankment and exist in bag longer between native discharging consolidation, filling earth bag between layers easily slip wait technical barrier.
Technical scheme:
Technical solution of the present invention constructs drainage channel by the processing of bag, the construction method of fill, band drain, four parts such as construction equipment selection of fill form.
The selection of bag is characterized in that the woven cloth geotextile tube bag or (woven cloth+non-woven fabrics) the acupuncture Compound Fabric geotextile tube bag that adopt the production of geotextile manufacturer, splicing is made and is formed Contiuum type filled geotube one by one again, and the diameter of filled geotube is about 1.2 meters or 1.6 meters.
The construction method of fill is characterized in that the function played according to mucky soil filling bag embankment, generally have and longitudinally lay and laterally lay two kinds of construction technologies, longitudinally laying is by geotextile tube bag along dike axis direction laying construction, and laterally laying is perpendicular to dike axis direction laying construction by geotextile tube bag.
Band drain is constructed in seam road that drainage channel is characterized in that adopting plastic draining board to be laid on the splicing of every layer of geotextile tube bag and the joint of segmentation dike.
The construction equipment of fill is selected to it is characterized in that (1) longitudinal laying construction facility adopt dredge pump+high-pressure hydraulic pump to carry out mud excavation, carry, charge bag.(2) horizontal laying construction facility adopt dredge pump+high-pressure hydraulic pump+auxiliary to charge facility to carry out mud excavation, carry, charge bag.
It is short that the technical program has bag draining seepage paths, band drain can effectively discharge excessive moisture in bag, bag and bag between because the fissure of displacement arranges mutual build-in, different laying methods can meet the different using function of dykes and dams, adopts special charging arrangement prodigiosin to meet the demand of construction.
The technical program has started the new approach of mucky soil filling bag embankment; have broad application prospects in riverine, coastal land reclamation embankment and dam construction; compared with existing sand filling bag fill; cost can save more than 20%, and opens up a Tiao Xin road for riverine, coastal ecological environmental protection.
Accompanying drawing illustrates:
What accompanying drawing 1 represented is the processing of mucky soil filling bag embankment bag, plastic draining slab pavement method schematic diagram.
What accompanying drawing 2 represented is mucky soil filling bag embankment construction method schematic diagram
What accompanying drawing 3 represented is mucky soil filling bag embankment construction auxiliary machine tool schematic diagram.
Detailed description of the invention:
Accompanying drawing 1: the processing of bag is by the geotextile tube bag 1 be once made into, one by one geotextile tube bag is connected by splicing sewing line 2, plastic draining board 3 is laid in the seam road of every layer of geotextile tube bag splicing, need overlay plastic draining board 3 when laying along dike axis direction 4 (longitudinal direction) in the joint of segmentation dike.
Accompanying drawing 2: the longitudinal construction technology of fill is by geotextile tube bag 1 along dike axis direction 4 laying construction, the horizontal construction technology of fill is perpendicular to dike axis direction 4 laying construction by geotextile tube bag 1.
Accompanying drawing 3: fill construction auxiliary machine tool is that the mud of being discharged by mud pipe 1 flows into arm 2, through the fill of valve 3 filling geotextile tube bag.
Claims (2)
1. a mucky soil filling bag embankment method, is characterized in that: the method is made up of following steps:
(1) tubular bag sews up: adopt the geotextile tube bag be once made into splice one by one and make formation Contiuum type filled geotube, the diameter of filled geotube is 1.2 meters or 1.6 meters;
(2) tubular bag is laid: adopt longitudinally laying or horizontal laying method to lay tubular bag, wherein longitudinally laying is by geotextile tube bag along dike axis direction laying construction, and laterally laying is perpendicular to dike axis direction laying construction by geotextile tube bag;
(3) drainage channel is constructed: lay plastic draining board in the seam road that every layer of geotextile tube bag splice and the joint of segmentation dike, formation drainage channel;
(4) selecting construction equipment to carry out tubular bag filling: when longitudinally laying tubular bag, adopting dredge pump and high-pressure hydraulic pump to carry out mud excavation, carry and charge; When laterally laying tubular bag, adopting dredge pump, high-pressure hydraulic pump and auxiliaryly charging facility and carry out mud excavation, carry and charge.
2. method according to claim 1, is characterized in that: describedly auxiliary charge facility and be made up of mud pipe, arm and valve, and its filling and pouring method is that the mud of being discharged by mud pipe flows into arm, through the fill of valve filling geotextile tube bag.
