FIG. 1 is a partial schematic front view of the present invention;

fig. 2 is a partially cut-away right view of fig. 1.

In the figure: 1 slope body, 2 gravel layers, 3 geotechnical cloth layers, 4 bolt anchors, 5 waterproof layers, 6 planting soil layers, 7 baffles, 8 plug bushes, 9 connecting strips, 10 first blocking platforms, 11 second blocking platforms and 12 water storage ditches.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 2, a seepage-proofing structure for a geotechnical engineering slope comprises a slope body 1, a sandstone layer 2 is laid on the slope surface of the slope body 1, the grading particle size of the sandstone layer 2 is 2 mm, the laying thickness of the sandstone layer 2 is 5 cm, a geotextile layer 3 is laid on the sandstone layer 2, bolt anchors 4 are uniformly inserted into the geotextile layer 3, the bolt anchors 4 penetrate into the slope body 1, the geotextile layer 3 is fixed through the bolt anchors 4, the geotextile layer 3 covers the sandstone layer 2, the permeation speed of water in the slope body 1 to a planting soil layer 6 can be reduced through the arrangement of the sandstone layer 2 and the geotextile layer 3, the geotextile layer 3 is coated with a waterproof layer 5, the waterproof layer 5 is a pure cement slurry layer, the thickness of the waterproof layer 5 is 2 cm, and the permeation rate of the slope body 1 to the planting soil layer 6 can be effectively reduced through the blocking of the waterproof layer 5.

Referring to fig. 1 and 2, a planting soil layer 6 is installed on a waterproof layer 5, the planting soil layer 6 is 40 cm thick, vegetation can be planted in the planting soil layer 6, baffles 7 are uniformly embedded in the planting soil layer 6 along the vertical direction, the baffles 7 are square plates with the side length of 1 meter, the height of the baffles 7 embedded in the planting soil layer 6 is 30 cm, pure cement slurry is uniformly coated on the front and rear adjacent baffles 7, after the pure cement slurry is solidified, the front and rear baffles 7 can be bonded together, the bonding part has good waterproofness, an inserting sleeve 8 is uniformly sleeved on the baffles 7 connected in the front and rear direction in an interference fit mode by taking five meters as a distance, the inserting sleeve 8 is of a U-shaped plate structure, connecting strips 9 are welded between the inserting sleeves 8, a first blocking platform 10 is placed at the top of a slope body 1, the first blocking platform 10 is of a right-angle plate structure, a second blocking platform 11 is installed at the bottom of the slope body 1, and the first blocking platform, downside baffle 7 contact second fender platform 11, the first fender platform 10 of plug bush 8 contact of the top, because all adopt connecting strip 9 to connect between the plug bush 8, consequently, support through first fender platform 10 and second baffle 11, it is more stable at planting soil layer 6 to make baffle 7 erect, and partly see through the water of planting soil layer 6, can be kept off by baffle 7 check, supply vegetation to use, retaining ditch 12 has been installed to the avris of second fender platform 11, retaining ditch 12 adopts the concrete prefabrication to form, the setting of retaining ditch 12, can collect and discharge the rainwater of whereabouts to other positions from the side slope in the rainy day.

Fix geotechnological cloth layer 3 through bolt anchor 4, make geotechnological cloth layer 3 cover gravel layer 2, through gravel layer 2 and geotechnological cloth layer 3's setting, can slow down the inside water of slope 1 to planting soil layer 6 permeation rate, block through waterproof layer 5, can effectively reduce slope 1 to planting soil layer 6 water permeability, because all adopt connecting strip 9 to connect between the plug bush 8, consequently, support through first fender platform 10 and second baffle 11, make baffle 7 erect and plant soil layer 6 more stable, and partly see through the water of planting soil layer 6, can be kept off by baffle 7 check, supply vegetation to use, thereby can prevent that the water from seeing through on side slope to the highway, prevention of seepage water nature is good.
