Specific implementation mode
The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.
As shown in Figures 1 to 5, the interface percolator of the earth rock cofferdam of the present embodiment and concrete cofferdam, including even
It connects steel plate 1, geomembrane 2 and compresses steel plate 3, junction steel plate 1 is embedded in advance in interface 4, and geomembrane 2 is layed in earth rock cofferdam 7
On in longitudinal section, and geomembrane 2 extends to covering junction steel plate 1 close to one end bending of interface 4, and compressing steel plate 3 will be geotechnological
Film 2 is pressed on junction steel plate 1 and is locked by fastening bolt 5.
In Fig. 1, junction steel plate 1 is embedded on the interface 4 of earth rock cofferdam 7 and concrete cofferdam 8.Native stone is embedded in enclose
It is seamless connection, the soil on interface 4 between geomembrane 2 (thick lines in Fig. 1) on geomembrane 2 in weir 7 and interface 4
Work film 2 is pressed on by compressing steel plate 3 on pre-buried junction steel plate 1, forms Sandwich biscuit type antiseepage, as shown in Figure 3.This knot
Structure reserves tooth socket in the prior art in concrete cofferdam 8, and geomembrane 2 gos deep into tooth socket, the company of backfill clay in tooth socket
The mode of connecing carries out antiseepage mode and compares, and the present embodiment Sandwich biscuit type percolator eliminates reserved tooth socket, reduces plank sheathing
