Abstract
A half-floral-tube type reinforcement and drainage composite component comprises a half-floral-tube type framework (1), graded sand and stones (2) are filled in the half-floral-tube type framework (1), a geotextile water filtration layer (3) covers the outer wall of the half-floral-tube type framework (1), and water seepage holes (4) are formed in the half-floral-tube type framework (1). The composite component has the advantages that the structural style and the manufacture process are simple, the operability is high, the manufacture cost is low, and the quality reliability is high; the applicable range is wide, and the composite component is applicable to both the soft foundation and the roadbed in the low-gravity-stress environment and the high and steep fill side slope and the tailing fill dam in the high-gravity-stress environment; the timeliness is high, the initial local stability during filling or stacking of fill bodies can be improved, and the whole stability of the fill bodies during the long-term operation can be improved.
Description
Technical field
The utility model relates to high steep embankment side slope and fills and tailing dam damming works technical field, and a kind of reinforcement that has concurrently oozes half floral tube formula composite component of two kinds of functions with row specifically.
Background technology
Under Persistent Heavy Rain effect, the soil body in side slope certain depth is by saturated softening, and soil shear strength reduces, and the seepage effect of underground water has also increased the sliding force of side slope simultaneously, and then causes slope stability sharply to decline.At tailing dam, building a dam in process, is the main cause that causes fill dam unstability because draining in time causes phreatic line rising in dam body.As can be seen here, at high gradient slope, filling and tailing dam is built a dam in process, how effectively to organize draining reduce in the body of slope phreatic line and how to lay the physical and mechanical property that reinforcement material strengthens filling body, is the key that class slope stability is filled in raising.
The patented product at present draining and reinforced action being combined mainly comprises two classes, and a class is to optimize conventional band drain structure, at band drain outside or inner reinforcement, makes band drain play reinforced action; Another kind of is that band drain is placed in geo-grid, thereby reaches draining and two kinds of effects of reinforcement.Above-mentioned two class patented products are mainly applicable to the little soft base of general buried depth and little roadbed and the embankment side slope of filled height, for filled height larger embankment side slope and tailing dam, because plastic draining board self compressive strength is lower, easy deformation failure under higher selfweight stress effect, stop up drainage channel, lose drainability.Plastic draining board and reinforcing body (geo-grid) are difficult to form an organic whole in manufacture craft simultaneously, have both been not easy to large-scale production, while operation, complex process, and cost is high, and reliability is poor.
Summary of the invention
The purpose of this utility model is a kind of half floral tube formula composite component that has draining and two kinds of functions of reinforcement concurrently of design, can, under high selfweight stress ambient conditions, reach the function of reinforcement and long-term draining.Specifically make filling body fill or banking process initial stage quick-discharging consolidation, by row, ooze reinforcement and improve filling body physical and mechanical property, in later stage operation process, by long-term row, ooze simultaneously, guarantee that filling body underground water in heavy rain state or tailings discharging process mesoslope body can discharge in time, make phreatic line lower than designing requirement.
A kind of half floral tube formula reinforcement row of the utility model is oozed composite component, comprising: half flower tube-type framework, and graded sand and stone is filled in half flower tube-type framework, and geotextile drainage layer is wrapped in half flower tube-type framework outer wall, on half flower tube-type framework, is provided with water seepage hole.
Described half flower tube-type framework, adopt that fiber-reinforced plastic, steel are moulded, polypropylene, high density polyethylene (HDPE) or other every linear meter(lin.m.) hot strength >=15kN, the high-strength polymer fiber of hot strength elongation rate≤15% is made one section of external diameter 10cm by extruding, stretching, internal diameter 8cm, the pipeline of wall thickness 1cm, is mainly used in realizing reinforcement and skeleton function is oozed in the row of formation.
Described graded sand and stone, is filled in half fancy pipeline after adopting ratio that higher gravelly sand, coarse sand and the medium sand of transmission coefficient is 60:30:10 according to percentage to be made into, and is mainly used in the row of realization and oozes the function that skeleton is oozed in gallery and the row of support.
Described geotextile drainage layer, is around around one week geotextile, to make at half flower tube-type framework, and lap-joint connects closely by bonding or colligation, be used for the row of realization and ooze filtering function, to prevent that fine grained from passing through half floral tube water seepage hole and infiltrating, stop up drainage channel, reach the permeable effect of filter residue.
Described water seepage hole be within the scope of half flower tube-type framework first half φ=161 ° by eyelet longitudinal pitch 3cm, laterally angle is the eyelet that the aperture that 23 ° of quincuncial pile types are arranged is 1cm.
The advantage that a kind of half floral tube formula reinforcement row of the utility model is oozed composite component is: form of structure and manufacture craft are simple, workable, cheap, and reliability is high; Applied widely, be both applicable to soft base and roadbed under low selfweight stress environment, be also applicable to the steep embankment side slope of height and tailing dam under high selfweight stress environment; Ageing strong, can solve filling body filling or the local stability at banking process initial stage, can solve again the resistance to overturning of filling body in long-term operation process.
