The novel plastic drainage plate comprises a plastic cross-band veneer, truncated hemispherical bulges, a water seepage covering layer and stiffening ribs shaped like a Chinese character ''jing'', wherein the truncated hemispherical bulges are hollow bulges with downward openings; the top surfaces of the bulges are planes; the middle swelled parts of the bulges are hemispherical; the truncated hemispherical bulges are uniformly distributed on the upper surface of the plastic cross-band veneer to encircle into a drainage channel; shrinkage pools are formed in the lower surface of the plastic cross-band veneer; a layer of water seepage covering layer covers on the top surfaces of the truncated hemispherical bulges; and the stiffening ribs shaped like a Chinese character ''jing'' are regularly distributed on the smooth parts encircled by the shrinkage pools in the lower surface of the plastic cross-band veneer and are provided with sawteeth which are regularly distributed. Compared with drainage plates of other structural forms, the novel plastic drainage plate has the advantages that the carrying capability is strong, the rigidity is large, the deformation is not easy, and the drainage plate is tightly combined with a soil body and cannot easily slide.
Description
Technical field
The utility model relates to a kind of novel plastic band drain that has the sawtooth stiffening rib, belongs to building material field.
Background technology
Plastic draining board, is used widely in ground (embankment) is reinforced because it possesses good, the advantages such as efficiency of construction is high, good endurance of drainage effect as a kind of flabbiness ground strengthened and foundation drainage material.In addition, plastic draining board also has good effects such as antidetonation mitigation, protection environment, reinforcement reinforcement, horizontal drainage, bank protection in foundation engineering.In China, plastic draining board has become the most frequently used reinforced soft soil ground one of adrainage material, be encountered with many times in harbour, water conservancy, speedway, engineering construction such as reclaim fields from the sea, according to statistics, the use amount in the present plastic draining board of China every year is 1,000,000,000 linear meter(lin.m.)s nearly.
Plastic draining board bears the soil pressure effect in the soil body, at first act on the infiltration filter membrane, then is passed to quilted plastic panel.Therefore, plastic draining board need have certain intensity as a kind of architecture engineering material that bears pressure, is not damaged by pressure by soil pressure to guarantee band drain, avoids drainage channel to get clogged, and drainability is descended.At present, existing various band drain structures are similar substantially, all by basic unit, be positioned at cup-shaped or the columnar projections in the basic unit and cover cup-shaped or columnar projections on permeatable filter layer form.The plastic draining board upper surface protruding block of many manufacturer production is square or the taper cylinder, this form of structure not only makes current bigger in projection bottom flow resistance, drainage efficiency is low, and side direction pressure effect lower convexity place is stressed bigger in the soil body, often because its strength deficiency is damaged by pressure, and cause and cover filter membrane and lack and support and embed in a large number and cause in the drainage channel that the drainage channel area reduces greatly.In addition, existing plastic draining board is more smooth because of the base plate face, thus with the soil body surface of contact between be easy to generate relative slip and between contact surface, produce the gap, influence drain function.Recently, people show also that by indoor and field trial research the central layer of plastic draining board is when insufficient rigidity, and the compressive strain of band drain increases thereupon, and drainability can obviously descend or basic forfeiture.Above-mentioned problems all can have influence on the normal draining of plastic draining board, can cause that bearing capacity of foundation soil sharply reduces when serious, cause the Important Project accident.Therefore, how existing plastic draining plated construction is done further optimal design, have great economy and social effect.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of novel plastic band drain that has the sawtooth stiffening rib is provided, soft foundation (embankment) consolidation process and foundation drainage such as this novel plastic band drain can be used for harbour, water conservancy, speedway, reclaim fields from the sea, improve the soft foundation bearing capacity, can provide safe and reliable drainage condition for engineering construction, the reinforcing of guaranteeing soft foundation is complete, to ensure carrying out smoothly of soft clay area urban construction construction.
Create purpose for reaching foregoing invention, the utility model adopts following technical proposals:
A kind of novel plastic band drain that has the sawtooth stiffening rib, comprise quilted plastic panel, flat-top hemispherical projections, liquid-permeable floor covering and " well " font stiffening rib, described flat-top hemispherical projections is the hollow projection that Open Side Down, its end face is the plane, the centre is heaved part and is hemispherical, described flat-top hemispherical projections evenly is arranged in the upper surface of quilted plastic panel, surrounds drainage channel, at the soffit formation shrinkage pool of quilted plastic panel; The end face of described flat-top hemispherical projections is coated with one deck liquid-permeable floor covering; The level and smooth place that described " well " font stiffening rib regular distribution surrounds between the soffit shrinkage pool of quilted plastic panel, described " well " font stiffening rib has the sawtooth of regular distribution.
Above-mentioned quilted plastic panel is combined by basic unit and composite bed.
Above-mentioned flat-top hemispherical projections end face is positioned at 1/5th to 1/4th radius of sphericity places.
Above-mentioned liquid-permeable floor covering can be one deck nonweaven geotextile.
Above-mentioned liquid-permeable floor covering also can be one deck filter membrane.
The utility model has following substantive distinguishing features and advantage compared with prior art:
1. the utility model band drain projection adopts semi-spherical form, be subjected to the external force effect at spherical any place, power all can have been given full play to the compressive property of material to spreading out equably all around, so hemispherical projections is firmer, can bear bigger soil pressure effect.
2. the utility model band drain projection adopts semi-spherical form, can effectively reduce the flow resistance of pore water, improves drainage efficiency greatly.
3. the utility model band drain base plate face arranges " well " font stiffening rib, can improve the integral rigidity of quilted plastic panel, reduces its distortion, can prevent from effectively sliding relatively because of the contact surface that distortion produces.
4. the utility model band drain base plate face adopts " well " font stiffening rib form to increase integral rigidity, but not adopts the mode that increases central layer thickness, can save quantity of plastics more, has more economy.
5. the utility model band drain base plate face adopts and has jagged " well " font stiffening rib, can increase snap-in force and frictional force between band drain and the soil body, effectively prevents the generation in gap between the band drain.
6. the utility model plastics adopt the form that basic unit is combined with composite bed, have strengthened abrasion resistance, the corrosion resistance of band drain, thereby have improved the water resistance of band drain, increase the service life.
