Abstract
A kind of flexible vertical barrier system, including HDPE film and the mud off for being vertically set on groove both sides, multiple backfill bodies being sequentially overlapped from top to bottom, in triangular prism structure are provided between the both sides mud off, the HDPE film is continuously arranged along the mating surface between adjacent backfill body, the backfill body section is in isosceles triangle, apex angle α=40 °~50 ° of the isosceles triangle, the backfill body axial length is 1~1.5m, and the wedge shape backfills external wall and is surrounded by geotextiles.The utility model provides a kind of new flexible vertical barrier system, the protection more safe and feasible to HDPE film, it is ensured that the safe operation of vertical barrier system, while the setting of anchoring hook is eliminated, it can be widely applied to the repairing and treating field of soil.
Description
Technical field
The repairing and treating technical field of soil is the utility model is related to, more particularly to a kind of flexible vertical barrier system.
Background technology
Barrier landfill is one of technology the most frequently used in repairing and treating technology.By contaminated soil or the soil after improvement
It is placed in antiseepage barrier landfill yard, or stops the approach of pollutants in soil diffusion by laying barrier layer, makes Polluted Soil
Earth is isolated with surrounding environment, is avoided pollutant with human contact and is migrated with the soil water and then human body and surrounding environment are caused to endanger
Evil.Vertical barrier system is to obstruct the important component of Landfill.Vertical barrier system is the hydrology according to contaminated site
Geology, engineering geological condition, utilize independent hydrogeologic condition, impermeable stratum existing for landfill yard or contaminated site ground beneath
Deng in the vertical antiseepage barrier engineering of landfill yard or the setting of contaminated site periphery.The outside diffusion mobility of pollutant is prevented, while
Underground water is prevented to flow into landfill yard or contaminated site.
The laying method of HDPE film is mainly gravity plastic film mulch method in currently used flexible vertical barrier system, and top needs
Phenomena such as setting anchoring hook, fixed HDPE film is higher to construction requirement, and easily generation comes off, drawing crack destroys.The both sides of HDPE film
Backfilling material is generally the good material or mud of grading, and HDPE film, mud can be pierced through when containing sharp stone in material
Consolidation sedimentation can occur for the later stage, and downward pulling force can be also produced to film, be unfavorable for the safety of film.
Utility model content
The purpose of this utility model is to provide a kind of protection that can strengthen to HDPE film and ensures the vertical of safe operation
Barrier system.
A kind of flexible vertical barrier system, including HDPE film and the mud off for being vertically set on groove both sides, described two
It is provided with multiple backfill bodies being sequentially overlapped from top to bottom, in triangular prism structure between the mud off of side, the HDPE film is along phase
Mating surface between adjacent backfill body is continuously arranged.
Preferably, the backfill body section is in isosceles triangle, apex angle α=40 °~50 ° of the isosceles triangle.
Preferably, the backfill body axial length is 1~1.5m.
Preferably, the external side of backfill is surrounded by geotextiles.
Compared with prior art, the utility model has the advantages that：
1., it is used backfill material be geotextiles parcel backfill body, HDPE film can be effectively protected and do not pierced by sharp debris
Wear；
2., HDPE film using in a zigzag lay, can avoid because HDPE film caused by Action of Gravity Field and other external force takes off
Fall and destroyed with drawing crack；
3., eliminate need in the prior art system head set anchoring hook the step of, reduce workload.
Brief description of the drawings
Fig. 1 is the structural representation of flexible vertical barrier system described in the utility model.
Fig. 2 is the structural representation that wedge shape described in the utility model backfills body.
Embodiment
As shown in figure 1, a kind of flexible vertical barrier system, including HDPE film 1 and the mud for being vertically set on groove both sides
Retaining wall 2, multiple backfill bodies 3 being sequentially overlapped from top to bottom, in triangular prism structure are provided between the both sides mud off 2,
The HDPE film 1 is continuously arranged along the mating surface between adjacent backfill body 3.
As shown in Fig. 2 backfill body 3 section is in isosceles triangle, apex angle α=40 ° of the isosceles triangle~
50 °, the backfill axial length of body 3 is 1~1.5m, and the backfill outer wall of body 3 is surrounded by geotextiles 31.
Flexible vertical barrier system installation steps described in the utility model are as follows：
A, smooth location, excavate groove, the width of the groove be 0.8~1.0m, cutting depth regarding concrete condition and
It is fixed, typically it is excavated to 0.5~1.0m under impermeable stratum.The groove of excavation carries out mud off in time, prevents landslip of the sides of the trench.Such as
Underground water is met, answers timely pump drainage.
B, backfill body is made, backfilling material decimation stage matches somebody with somebody the good soil body, removes the sharp debris such as stone cleaning, branch, permeates
Coefficient should be less than being equal to 1 × 10-9M/s, and there is certain compactness.The section of backfill body is in isosceles triangle, the isosceles
The apex angle α of triangle takes 40 °~50 °, and backfill body axial length takes 1~1.5m, and backfill wraps up in geotextiles in vitro.
C, HDPE film is laid upwards since trench bottom, often lays one-level, is laid one piece of backfill body, is backfilled body and HDPE film
Between should be in close contact.Upper and lower two-stage backfill body answers the fissure of displacement to lay.Use and be welded to connect between adjacent HDPE film.Due to HDPE film into
Lay, and be compacted by backfill body in a zigzag, therefore the setting of top anchor hook can be saved.
Compared with prior art, the utility model has the advantages that：
1., it is used backfill material be geotextiles parcel backfill body, HDPE film can be effectively protected and do not pierced by sharp debris
Wear；
2., HDPE film using in a zigzag lay, can avoid because HDPE film caused by Action of Gravity Field and other external force takes off
Fall and destroyed with drawing crack；
3., eliminate need in the prior art system head set anchoring hook the step of, reduce workload.
Preferred embodiments of the present utility model are the foregoing is only, it is all new in this practicality not to limit the utility model
Within the spirit and principle of type, any modification, equivalent substitution and improvements made etc., protection model of the present utility model is all contained in
Within enclosing.
