Abstract
The utility model discloses a bank-based geomembrane system, which comprises anchoring grooves (4) arranged on mountains at two sides, wherein a dam body (3) is arranged between the anchoring grooves (4) at the two sides, a geomembrane (2) is arranged at the joint of the downstream side of the dam body (3) and the anchoring grooves (4), and a geomembrane protective layer (1) is arranged at the outer side of the geomembrane (2); and two ends of the geomembrane (2) are anchored in the anchoring grooves (4) after being wound on the dam body (3). The utility model discloses can adapt to the dam body and warp, can avoid stress concentration, prevent that the geomembrane from tearing, avoid the prevention of seepage body inefficacy.
Description
Technical field
A kind of geotechnological membranous system is the utility model is related to, particularly a kind of geotechnological membranous system of bank base position.
Background technology
In Hydraulic and Hydro-Power Engineering, geomembrane is had been widely used in engineering practice as impervious body.Dam body with
The bank base position that massif connects, geomembrane deformation is maximum, and the stress born is maximum.Existing anchorage style by being rigidly connected,
The deformation of dam body can not be well adapted to, geomembrane is also easy to produce tear at the position, causes impervious body tear failure.
The content of the invention
The purpose of this utility model is, there is provided a kind of geotechnological membranous system of bank base position.The utility model can adapt to
Dam deformation, stress concentration can be avoided, prevents geomembrane from tearing, avoids impervious body from failing.
The technical solution of the utility model：A kind of geotechnological membranous system of bank base position, includes on the massif of both sides
Anchor slot, dam body is provided between the anchor slot of both sides, dam body downstream and the junction of the anchor slot are provided with geomembrane, geotechnological
The outside of film is provided with geomembrane protective layer；The both ends of the geomembrane are anchored in anchor slot after being unrolled on dam body.
The geotechnological membranous system of foregoing bank base position, the thickness of the geomembrane protective layer are more than 30cm.
The geotechnological membranous system of foregoing bank base position, the geomembrane are anchored in anchor slot, are tamped using flexible clay.
The geotechnological membranous system of foregoing bank base position, the geomembrane protective layer are stone-laying or concrete slab.
The geotechnological membranous system of foregoing bank base position, the geomembrane are anchored at part >=1.5m in anchor slot.
The beneficial effects of the utility model：
1st, the utility model by being anchored in anchor slot again after geomembrane is unrolled on dam body, after dam body water storage
When downstream deforming, geomembrane can follow dam body to swim deformation downwardly together, will not produce stress in bank base link position
Concentrate, can prevent geomembrane from tearing, the situation for avoiding impervious body from failing occurs.
, the utility model by the way that the thickness of geomembrane protective layer is set greater than into 30cm, geomembrane can be played compared with
Good protective effect, ensure that geomembrane does not cause aging by ultraviolet radiation.
, the utility model anchor slot is tamped by using flexible clay, be backfilling and compacted and compare compared to conventional concrete, this
The anchorage style of utility model can preferably play the effect for preventing that geomembrane from tearing.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model；
Description of reference numerals：1- geomembrane protective layers, 2- geomembranes, 3- dam bodys, 4- anchor slots.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment of the present utility model：
A kind of geotechnological membranous system of bank base position, as shown in Figure 1, include the anchor slot 4 on the massif of both sides, two
Dam body 3 is provided between the anchor slot 4 of side, the downstream of dam body 3 and the junction of the anchor slot 4 are provided with geomembrane 2, geomembrane 2
Outside be provided with geomembrane protective layer 1；The both ends of the geomembrane 2 are anchored in anchor slot 4 after being unrolled on dam body 3.
The thickness of the geomembrane protective layer 1 is more than 30cm, and specific thickness is depending on practice of construction environment needs.
The geomembrane 2 is anchored in anchor slot 4, is tamped using flexible clay.
The geomembrane protective layer 1 is stone-laying or concrete slab.
The geomembrane 2 is anchored at part >=1.5m in anchor slot 4.
Operation principle：Dam foundation when geomembrane 2 anchors first along dam body 3 is wrapped up, along dam body 3 and basic contact surface
Laying of unrolling is carried out, length of unrolling is more than 1.0m, is then anchored at the anchor slot 4 of lower section again, geotechnological when dam deforms
Film 2 follows the dam foundation together, avoids geomembrane 2 from tearing or be drawn out.Substituted simultaneously by the way of being unrolled in clay anchor slot 4
The anchorage style of original bolt anchor slot.
