Description
Technical field
The present invention relates to technical field of civil engineering, and in particular to a kind of anti-filter draining ball and its construction method.
Background technology
Loaded filter is set after retaining wall, infiltration draining is acted primarily as, is filtered the effect of soil conservation.The infiltration of subsoil water can cause gear
The hydrops of the cob wall rear portion soil body, form water pressure, when body of wall spilled water hole is unimpeded, easily form water passage, form infiltration broken
Bad, i.e., in the soil body, the tiny soil particle in part is taken away to form the seepage failures such as piping, stream soil by seepage water；If sluicing hole plug, wall
Water in the back of the body soil body cannot be discharged in time, water content of soil increase, make soil pressure increase, retaining wall foundation strength and resistance after wall
Shape reduced capability, easily forms basesliding or retaining wall destruction.Therefore, the loaded filter after retaining wall is to structure safety and the soil body
It is stable all critically important, should ensure that the water in the soil body is discharged in time, while the seepage failure of the soil body need to be prevented.
At present, anti-filter layer material mainly has graded broken stone, geosynthetics, non-fine concrete, geotextiles package-level to match somebody with somebody
Rubble and anti-filter draining board etc., they respectively have pluses and minuses, although such as sandstone class loaded filter material source is convenient, expense is relatively low,
Non-deformability is strong, good endurance etc., but it is considerably complicated to generally require to increase in construction volume of excavation, construction technology, overall
Property it is poor, easily by flowing water sapping, difficult quality control.Geosynthetics as after loaded filter, due to the strength of materials not
Foot, is affected with thickness by soil pressure, is easily caused material effective drainage porosity and changes, make material the feelings such as silting occur
Condition.The anti-filter effect of anti-filter draining board is good, but is difficult to be connected between draining board and retaining wall osculum, and construction and installation are not
Just.
The content of the invention
The invention provides a kind of anti-filter draining ball and its construction method, overcome the easy silting of anti-filter geotextiles, anti-filter
The problem of energy rapid decrease；During the design of spherical structure ensure that the soil body, water smoothly enters cavity, and retaining wall PVC drain pipe can be straight
Connect and be connected with anti-filter ball, solve the problems, such as that other loaded filter current are difficult to focus on drain pipe, can be in factory process, scene is straight
Connect installation, it is to avoid the problem of sand gravel loaded filter complicated construction technique and difficult quality control.
For achieving the above object, the technical scheme taken of the present invention is：
A kind of anti-filter draining ball, the anti-filter draining ball are hollow sphere and are covered with the entirety of inlet opening and an outlet
Formula composite construction, the overall diameter of the anti-filter draining ball is 220mm, and interior diameter is 190mm；A diameter of 10mm of inlet opening,
Even to be distributed on ball wall, the centre of sphere angle in adjacent inlet opening in the heart is 20 degree；The discharge outlet is one, is that ball wall is opened
Mouthful, a diameter of 60mm；Permeable fiber is filled with the discharge outlet, permeable 0.012～0.015g of fiber is filled per hole.
Preferably, the permeable fiber is hydrophilically modified fiber.
Preferably, the material of the anti-filter draining ball is polrvinyl chloride.
A kind of construction method of above-mentioned anti-filter draining ball is：
To execavated rockmass retaining wall：
S1, earth excavation；
S2, after the wall for needing draining place anti-filter draining ball, it is desirable to bottom soil body is closely knit, and outlet is outside；
S3, the PVC drain pipe of diameter 5cm is connected to draining ball outlet, drain pipe stretches out body of wall concordant with metope；
S4, continuation retaining wall construction, wall back of the body backfill.
To fill retaining：
S1, needing draining layer position place anti-filter draining ball, it is desirable to bottom soil body is closely knit, and outlet is outside；
S2, the PVC drain pipe of diameter 5cm is connected to draining ball outlet, drain pipe stretches out body of wall concordant with metope；
S3, continuation retaining wall construction, layering are banketed；
S4,2 to 3 layers of drain pipe, spacing 1m can be set to fine grained soil；One to two-layer only can be set to sand.
The invention has the advantages that：
Using the higher plastics of comprcssive strength as ball material, simultaneously because arching of the spheroid in the soil body, anti-filter
Hollow ball can bear larger soil pressure and not destroy；The fibrous material filled in aperture hardly receives soil pressure, overcomes anti-
The filter easy silting of geotextiles, because of compression anti-filter performance rapid decrease problem；The design of spherical structure, it is ensured that in the soil body
Water smoothly enters cavity from around, and retaining wall PVC drain pipe directly can be connected with the outlet of anti-filter draining ball, solve other
Loaded filter shipwreck is focusing on the problem of drain pipe；The present invention can be mounted directly in factory process, scene, it is to avoid sand gravel is anti-
Filtering layer complicated construction technique and the problem of difficult quality control.According to the filter effciency test result of loess, draining ball is in 50cm undergrounds
The lower test of head effect reaches steady in a long-term after 6 hours（Test 72 hours）, its average anti-filter displacement is 43ml/min.
Description of the drawings
