Description
Technical field
The utility model relates to a kind of anti-filter device for retaining wall draining.Be applicable to technical field of civil engineering.
Background technology
Retaining wall is widely used in the engineering constructions such as water conservancy, traffic, harbour Ji Gong China Democratic National Construction Association, its objective is that a barricade back of the body bankets or the hillside soil body, prevents soil deformation unstability.When water level after retaining wall 1 wall compared with high and before wall water level lower or when anhydrous, be to reduce the horizontal thrust that retaining wall bears, need arrange that drain hole 3 is with water level after reducing wall at wall body.Meanwhile, take rolling earth behind retaining wall out of when preventing draining, need anti-filter be set in drain hole import department.
At present, the pattern that arranges of conventional anti-filter has loaded filter and anti-filter bag.In the time that retaining wall 1 is highly lower, carries on the back full section along wall loaded filter 4 is set, as shown in Figure 1.In the time that retaining wall 1 is highly higher, along wall back of the body vertical direction interval, anti-filter bag 5 is set, as shown in Figure 2.
Filter material in above-mentioned loaded filter and anti-filter bag need be laid layer by layer, and construction sequence is loaded down with trivial details.In addition, filter material is outer is subject to backfill 2 shock effects without any protection, and especially outermost geotextiles, fold, displacement and distortion easily occur, and its anti-filter effect is difficult to ensure.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of anti-filter device for retaining wall draining simple in structure, easy to make, to ensure anti-filter effect, save the engineering time.
The technical scheme that the utility model adopts is: for the anti-filter device of retaining wall draining, the backfill of waterwall dorsal part has backfill, waterwall wall body is arranged drain hole, in drain hole water inlet, anti-filter device is set, it is characterized in that: described anti-filter device is made up of PVC reduced pipe, porous PVC plate and permeable geotextiles, described PVC reduced pipe is divided into path section and large footpath section vertically, its bonding porous PVC plate in small diameter section end, layering filling rubble and coarse sand in PVC reduced pipe, section end, large footpath is wrapped up permeable geotextiles and is also fixed with galvanized wire colligation; Described path section external diameter and drain hole aperture are suitable and be flush-mounted in wall body drain hole.
Described porous PVC plate is the circular slab of the external diameter such as diameter and described path section, is covered with the water hole that aperture is 10～15mm on it.
Described ballast grain sizes is 20mm left and right, and described coarse sand particle diameter is 1～4mm.
Bonding by adhesive between described PVC reduced pipe path section and drain hole.
The beneficial effects of the utility model are: 1, in the utility model, anti-filter device can be made in factory process, only need on-the-spot setting-in, easy to use, save the duration.2, in the utility model, permeable geotextiles is wrapped in PVC reduced pipe one end and fixes with galvanized wire colligation, is difficult for displacement and fold occur, and can not affect anti-filter effect.3, adopt the PVC reduced pipe with path section and large footpath section, be convenient to install location.4, material is simple, easily makes easy construction.

Detailed description of the invention
As shown in Figure 2 and Figure 3, the present embodiment is a kind of anti-filter device for retaining wall draining, there is funnel shaped PVC reduced pipe 6, porous PVC plate 7 and permeable geotextiles 9, wherein PVC reduced pipe 6 is divided into vertically path section 602 and large footpath section 601 (large footpath section diameter is greater than path section diameter, and drain hole 3 apertures of path section external diameter and waterwall 1 are suitable), porous PVC plate 7 is and the circular slab of path section 602 external diameters such as grade, on it, be covered with the water hole that aperture is 10～15mm (or with common PVC plate make, later stage perforate).
In this example, porous PVC plate 7 is adhered to path section 602 ends, the interior Lower Half of PVC reduced pipe 6 (in path section) filling particle diameter is the rubble 11 of 20mm left and right, the coarse sand 10 that pipe shaft first half filling particle diameter is 1～4mm, the section end, large footpath of reduced pipe is wrapped up permeable geotextiles 9 and is also fixed on PVC reduced pipe 6 with galvanized wire 8 colligations.In the present embodiment, permeable geotextiles 9 plays first reverse filter effect, and coarse sand 10 plays second reverse filter effect, and rubble 11 plays last one reverse filter effect.
When on-the-spot installation, the path section of PVC reduced pipe 6 602 whole body are coated with to adhesive, are flush-mounted in the gutter 3 of waterwall 1, large footpath section 601 is exposed outside drain hole, towards meeting native side, then, at waterwall 1 wall dorsal part backfill backfill 2, the bottom of backfill is compacted clay 12.
