Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1-3, a channel inflation soil side slope protection structure, including bank protection 1, 1 top of bank protection is equipped with horizontally baffle 2, is equipped with water catch bowl 3 on baffle 2, and 1 internally connected with of bank protection has several through slip casting reinforced anchor rods 5, anchor rods 5 equidistance distributes and sets up along 1 slope of bank protection, and anchor rods 5 top is passed bank protection 1 and is linked firmly the couple 15 of U type, 1 bottom of bank protection is equipped with several horizontally water drainage tank 11, and water drainage tank 11 top is connected with drain pipe 6, drain pipe 6 is located inflation soil side slope 4 and slope and sets up downwards, is equipped with several wash port 13 on the drain pipe 6, and wash port 13 is connected with the guide plate 14 of slope, 1 surface of bank protection covers in proper order has waterproof geotechnological cloth 8, rock-fill layer 9 and protection network 10, protection network 10 fixes on rock-.
This structure is mainly fixed the native side slope 4 of inflation through bank protection 1, can also play waterproof and drainage's effect to inside inflation soil simultaneously, and fundamentally solves the native side slope 4 of inflation because moisture is too much to lead to the problem of dilatational strain, can also plant green planting on 1 surface of bank protection simultaneously, not only further carries out the lock water reinforcement to the side slope, can also strengthen the aesthetic property of overall structure.
Preferably, when the slope protection device is used, firstly, the slope protection 1 is installed on the surface of a side slope through the anchor rods 5, the side slope is reinforced by one layer, the top baffle 2 of the slope protection 1 shields rain water, dew and the like on the sky, excessive moisture in the side slope is avoided, the rainwater and the like can be collected by the water collecting grooves 3 on the baffle 2 and flows into the drainage grooves 11 through the diversion grooves 20 below to be discharged, and therefore the water content in the side slope is reduced; simultaneously, waterproof geotechnological cloth 8 on bank protection 1 surface also can play the effect of water proof, prevents that moisture infiltration from advancing in the inflation soil side slope 4, has solved the problem of side slope expansion deformation from the source.
Furthermore, except for adopting a waterproof means, the structure also adopts the drain pipe 6 for draining, when the water content in the side slope is too much, the water content in the expansive soil side slope 4 can not be completely absorbed and can flow into the drain hole 13 along the guide plate 14, so that the water flows into the lower drain groove 11 from the drain pipe 6, and the redundant water content in the side slope is further discharged, the water content in the expansive soil side slope 4 can be effectively reduced, the expansion and shrinkage deformation of the expansive soil is reduced, and the deformation of the expansive soil is avoided; waterproof geotechnique's cloth 8 is mainly fixed through piling up of rock-fill layer 9, and the protection network 10 on rock-fill layer 9 surface then can protect rock-fill layer 9, avoids the rubble to drop to protection network 10 mainly connects fixedly through the couple 15 at stock 5 top, the change and the installation of the protection network 10 of being convenient for.
Further, the revetment 1 is arranged in parallel along the surface of the expansive soil side slope 4, and the included angle between the revetment 1 and the horizontal plane is 20-60 degrees; slope protection 1 is a certain angle of inclination with the horizontal plane for moisture in the slope protection 1 can flow out fast under the action of gravity, has accelerated the moisture velocity of flow, thereby can prevent the deformation of inflation soil side slope 4 in the short time.
Furthermore, a plurality of layers of filter screens 12 are arranged in the drain hole 13, and the diameters of the filter screens 12 are reduced from top to bottom; the water in the expansive soil side slope 4 can flow into the drain hole 13 through the guide plate 14, and simultaneously, a large amount of slurry can be mixed, so that a plurality of layers of filter screens 12 are arranged to filter the slurry, and the loss of the soil in the side slope is reduced.
As shown in fig. 4, the rock heap 9 is formed by sequentially stacking a coarse sand layer 16, a gravel layer 17, a concrete stone layer 18 and planting soil 19, wherein the planting soil 19 is non-expansive soil 4; the rock-fill layer 9 is mainly stacked on the surface of the waterproof geotextile 8 for fixing, and can play a certain waterproof role at the same time; the planting soil 19 is used for planting green plants, and can not only lock water and reinforce the slope, but also enhance the aesthetic property of the whole structure.
As shown in fig. 5, the left and right sides of the revetment 1 are provided with diversion trenches 20, and the upper and lower ends of the diversion trenches 20 are respectively connected with the water collection tank 3 and the drainage tank 11; the guide groove 20 is mainly used for guiding and discharging water on the water collecting tank 3 and the revetment 1 into the drainage groove 11.
As shown in fig. 6, the top of the anchor rod 5 is rotatably connected with an anchor head 7, one end of the anchor head 7 is provided with two conical expansion shells 21, and an annular clamping sleeve 22 is arranged inside the anchor head 7; when the anchor rod 5 is used, firstly, the anchor rod 5 is arranged in a drill hole, the expansion shell 21 is in a closed state initially, then, the anchor rod 5 is pulled backwards, the anchor head 7 slides relative to the rod body, and because the contact area between the outer surface of the expansion shell 21 and surrounding rock is large, the expansion shell 21 is expanded under the action of the friction force of the surrounding rock, so that the anchor head 7 is fixed between the surrounding rock, and finally, the anchor rod 5 is completely fixed by grouting in the drill hole; the cutting ferrule 22 in the anchor head 7 limits the rod body, and the rod body is prevented from moving out of the anchor head 7.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
