Detailed description of the invention
Hereafter will describe the specific embodiment of the invention in detail in conjunction with concrete accompanying drawing.It should be noted that the combination of technical characteristic or the technical characteristic described in following embodiment should not be considered to isolated, they can mutually be combined thus be reached better technique effect.In the accompanying drawing of following embodiment, the identical label that each accompanying drawing occurs represents identical feature or parts, can be applicable in different embodiment.
A kind of Unidirectional water permeable roadbed along river barricade, a kind of Unidirectional water permeable roadbed along river barricade schematic cross-sectional view as shown in Figure 1, described Unidirectional water permeable roadbed along river barricade comprises wall body 1 and substrate 2, described wall body 1 comprises metope 11, wall top 12 and the wall back of the body 13, the described wall back of the body 13 is with roadbed filling close proximity, described metope 11 is towards river, described wall top 12 is connected with roadbed end face, the described wall back of the body 13 is provided with Unidirectional water permeable material layer 3, described Unidirectional water permeable material layer 3 comprises hollow net support 31 from left to right successively, fiber soil material layer 32, Unidirectional water permeable geotextiles 33, described hollow net support 31 is with wall back of the body close proximity.
Described Unidirectional water permeable material layer 3 thickness is 163mm ~ 255mm, specifically can be 163mm, 170mm, 175mm, 180mm, 190mm, 200mm, 230mm, 240mm, 255mm.Described hollow net support layer 31 thickness is 60mm ~ 100mm, specifically can be 60mm, 70mm, 80mm, 90mm, 100mm.Described hollow net support is the Plastics Geogrids of uniform through hole 20mm × 20mm.
Described fiber soil material layer 32, thickness is 100mm ~ 150mm, specifically can be 100mm, 110mm, 120mm, 140mm, 140mm, 150mm.The material of described fiber soil material layer 32 is the composite material that sand and continuous fiber are formed, for the native compound of uniform fiber one, sand adopts the particle diameter near subgrade river side to be less than the river sand of 5mm, fibrous material is polyester fiber, the fibre that every bar polyester fiber is 20 μm by 60 diameters forms, in fiber soil material layer 32, the mass percentage content of fibrous material is 0.3%, jet fiber filate uniformly compound while of during injection sand.
Be illustrated in figure 2 the schematic longitudinal section of a kind of Unidirectional water permeable roadbed along river of the present invention barricade wall body, described spilled water hole 4 runs through wall body 1, and described spilled water hole 4 is carried on the back 13 by wall and is through to metope 11 obliquely.The angle that the straight line at described spilled water hole 4 place and the horizontal plane at described substrate 2 place are formed is 25 ° ~ 50 °.The effect arranging spilled water hole 4 is for after drainage wall, soil body moisture provides passage, rapidly ponding after eliminating wall, and after preventing wall, ponding forms hydrostatic pressure.Barricade should arrange spilled water hole 4 according to water percolating capacity at the suitable At The Height of wall body.Spilled water hole 4 scale visual bleeder quantity size adopts the circular hole of diameter 5 ~ 10cm respectively, or 5cm × 10cm, 10cm × 10cm, 15cm × 20cm square hole.Spilled water hole 4 spacing is generally 2 ~ 3M, is crisscross arranged up and down.Descend most bottom the spilled water hole 4 of row to exceed the above 0.3m of ordinary water level in roadbed along river immersion barricade, to avoid the outer flow backwards of wall.
In work progress, the Unidirectional water permeable material layer 3 that one deck has Unidirectional water permeable function is set inside the wall back of the body 13.This Unidirectional water permeable material layer 3 has hydrophilic properties for side, opposite side has the unidirectional permeable layer of hydrophobic nature, by arrange this kind of Unidirectional water permeable material layer 3 reach to realize inside the barricade wall back of the body 13 moisture can through, import spilled water hole 4 and be discharged to the object that the outer river course of wall carries out roadbed drainage, and can realize stoping the moisture outside metope 11 in river to pass through and entering the object inside the wall back of the body 13, effectively control humidity that roadbed along river filler causes because river infiltrates and cross the problem of wetting.
Be illustrated in figure 3 longitudinal drainage tubular structure schematic diagram of the present invention.Described hollow net support 31 lowermost end is provided with longitudinal drainage pipe 5.Described longitudinal drainage pipe 5 has permeable hole 51 towards the side of hollow net support 31, and described permeable hole 51 is circular port, and described circular port diameter is 5 ~ 10cm, specifically can be 5cm, 6cm, 7cm, 8cm, 9cm, 10cm; Pitch of holes is 15 ~ 40cm, specifically can be 15cm, 20cm, 25cm, 30cm, 35cm, 40cm.The gross area of described permeable hole 51 accounts for 25% ~ 40% of described longitudinal drainage pipe 5 surface area, specifically can be 25%, 30%, 35%, 40%.When immersion amount is more, spilled water hole cannot meet displacement, and the water in hollow net support 31 can enter in longitudinal drainage pipe 5 by permeable hole 51 under gravity, discharges from the two-port of longitudinal drainage pipe 5.
By the process to conventional earth working material top layer, make that earth working material side is hydrophilic, side hydrophobic, be presented as barricade wall carry on the back close-connected Unidirectional water permeable material layer both sides surface wettability can difference.The Unidirectional water permeable earth working material arranged in wall-retaining structure can make water droplet from its drainage blanket side to hydrophilic layer side through, then can not be through from hydrophilic side to hydrophobic side.Geotextiles treatment comprises the following steps: the solution that a, geotextiles fabric lining are put into containing hydrophilic additive soaks; B, oven dry; The sizing of c, geotextiles fabric lining also dips surfactant simultaneously; D, oven dry; E, to utilize coating technology in the side of geotextiles fabric lining by hydrophobic auxiliary agent and some auxiliary addition agents as adhesive, acetic acid etc., be distributed to fabric top layer, side; F, oven dry.Geotextiles fabric lining carries out decationizing process before carrying out coating process, makes zwitterion reach balance, or cation is little, almost can ignore.Geotextiles fabric lining is pure-cotton fabric or the fabric of cotton content more than 50%.Bake out temperature is between 80 DEG C ~ 170 DEG C degrees Celsius.By preceding method, the process on geotextiles top layer is formed to the geotextiles fabric lining with unidirectional water seepage function.
A kind of Unidirectional water permeable roadbed along river of the present invention barricade, this barricade effectively can carry out the protection of immersion roadbed, realizes the function of roadbed along river barricade Unidirectional water permeable, by controlling the discrepancy of moisture, reach the object of Dominating paths backbone wet condition, the final generation effectively reducing roadbed along river Water Damage.
