Description
Technical field
The utility model belongs to construction engineering technical field, relates generally to a kind of replace graded sand and stone with pervious concrete
Prefabricated anti-filter bag.
Background technology
In the engineering constructions such as water conservancy, municipal administration, traffic, harbour, be widely applied to retaining wall, be mainly used to support it is natural or
Artificial earth fill's side slope, keep soil stabilization.To prevent that ponding forms hydrostatic pressure after wall, retaining wall should set drainage measure,
At present, retaining wall draining generally uses drainpipe draining, to prevent piping, graded broken stone anti-filter need to be set after drainpipe
Wrap or fill graded broken stone loaded filter.
During construction, anti-filter bag is typically directly made at the construction field (site), some are osculum outsourcing geotextiles, then with level
Wrap up with sand, finally wrapped up in outermost layer with graded broken stone；And some are directly deposited in draining with geotextiles parcel graded sand and stone
At pipe.Many drawbacks often be present in this conventional construction method：First, construction worker is inadequate to the understanding of importance of anti-filter bag,
The construction quality of anti-filter bag is difficult to control；Second, the graded broken stone site operation inconvenience in anti-filter bag is, it is necessary in constructing soil
Part construction anti-filter bag is reserved when square；Third, anti-filter bag size, shape are extremely difficult to the requirement of design in constructing at the scene, not
" filter soil " function of anti-filter bag is played completely；Fourth, when infiltration is larger, graded broken stone can be broken up by current, and draining is blocked in the earthwork
Hole, it is impossible to draining.There are problems that in the traditional construction of anti-filter bag numerous defects and, influence the stability of retaining wall, bring tight
The potential safety hazard of weight.
Utility model content
To solve the above problems, the utility model provides a kind of prefabricated anti-filter bag simple in construction, easy for construction, can
Engineering time, accelerating construction progress are saved, and can effectively controls loaded filter construction quality, ensure that anti-filter effect, maintain wall
The stability of the soil body after body and wall.
In order to solve the above-mentioned technical problem, the utility model proposes following technical scheme：It is a kind of for retaining wall draining
Prefabricated anti-filter bag, more drainpipes is disposed with regular intervals in the wall body of retaining wall, the water inlet of the drainpipe is set
Anti-filter bag is equipped with, the anti-filter bag includes collector pipe, pervious concrete, permeable geotechnological textile cloth and permeable geotextiles filter screen, institute
The one end for stating collector pipe is connected with drainpipe, and is mounted to inside drainpipe, and sealing water-proofing treatment is done with fluid sealant, collector pipe
The other end is fixed on inside pervious concrete, and its end is machined with inclined-plane, and permeable geotextiles filter screen bag is used on its inclined-plane
Wrap up in, and with galvanized wire banding fixed；The outer layer of the pervious concrete is wrapped up with permeable geotechnological textile cloth, and in collector pipe and permeable
Sealing water-proofing treatment is done at concrete combined outside.
The collector pipe is made of pvc pipe material, and its diameter is less than the diameter of drainpipe, can be adapted to draining
Pipe.
The drainpipe is made of pvc pipe material.
The permeable geotechnological textile cloth is at least provided with one layer.
The pervious concrete can be permeable and has certain intensity.
The utility model has the advantages that：
1st, in the utility model prefabricated anti-filter bag can standardized production as needed, its size can determine according to design requirement
System, it can be made in advance in factory process, can ensure that the quality safety of anti-filter bag is reliable.
2nd, prefabricated anti-filter bag is transported to job site, directly arrangement installation, construction from factory in the utility model
It is simple and easy, shorten the engineering time, use manpower and material resources sparingly, and can effectively controls construction quality, improves efficiency of construction.
3rd, conventionally employed graded broken stone is replaced using pervious concrete in the utility model, pervious concrete globality compared with
It is good, it is not easy to flow, avoids being broken up and lose " filtering native draining " function.
4th, three layers of anti-filter are set, and being seeped water after wall passes through permeable geotechnological textile cloth, pervious concrete, permeable geotextiles filter screen three
Layer is filtered, then is collected to PVC collector pipes, is discharged by drainpipe outside wall, gives full play to " filtering native draining " work(of anti-filter bag
Energy, be advantageous to the stabilization of retaining wall.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is section structure diagram of the present utility model.
Fig. 2 is arrangement retaining wall sectional schematic diagram of the present utility model.
In figure：It is retaining wall 1, drainpipe 2, anti-filter bag 3, collector pipe 4, pervious concrete 5, permeable geotechnological textile cloth 6, permeable
Geotextiles filter screen 7.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
Such as Fig. 1-2, a kind of prefabricated anti-filter bag for retaining wall draining, the wall body of retaining wall 1 row of arrangement at regular intervals
Water pipe 2, sets anti-filter bag 3 in the water inlet of drainpipe 2, and the anti-filter bag 3 includes collector pipe 4, pervious concrete 5, permeable
Geotechnological textile cloth 6 and permeable geotextiles filter screen 7, the collector pipe 4 is exceptionally held and the inner, and outer end is mutually fitted with the water inlet of drainpipe 2
Match somebody with somebody, be embedded into drainpipe 2, handled with fluid sealant waterproof sealing, collector pipe 4 is inner to be fixed in pervious concrete 5, PVC collection
