In order to solve the problems, the technical scheme of the utility model is as follows:
the utility model provides a pumped storage power station dam slope reinforcing apparatus, includes protects the slope board and a plurality of reinforcement section of thick bamboo, consolidate the section of thick bamboo and be the toper, consolidate the thinner one end of section of thick bamboo and be connected with the slip casting pipe, consolidate the thicker one end of section of thick bamboo and be equipped with the toper plug, the slip casting pipe passes protects the slope board, has seted up a plurality of grout holes on consolidate the section of thick bamboo surface, consolidates fixedly connected with fin on the section of thick bamboo outer wall towards plug one end at the grout hole, and plug maximum diameter is greater than consolidates a maximum diameter.
The grouting device further comprises a threaded steel bar, one end of the threaded steel bar sequentially penetrates through the grouting pipe and the reinforcing cylinder and then is fixedly connected with the conical plug, and a threaded groove is formed in the conical surface of the conical plug.
One end of the grouting pipe is connected with a sealing cover in a threaded manner.
A plurality of jacks are formed in the slope protection plate, and connecting rods are inserted into the jacks.
The beneficial effects of the utility model are as follows: after inserting the reinforcing cylinder into the soil body, pouring the fastening agent into the reinforcing cylinder, and anchoring the reinforcing cylinder and the soil body by utilizing the solidification fastening agent, so that the reinforcing cylinder and the soil body are firmly combined, a barb anti-pulling structure is formed, the gripping force between the reinforcing cylinder and the soil body is enhanced, the reinforcing strength of the slope protection plate to the dam slope of the power station is increased, and the situation that the reinforcing device is separated from the side slope is effectively avoided.
Drawings
The utility model is further described with reference to the accompanying drawings:
figure 1 is a schematic perspective view of the present utility model,
figure 2 is a schematic perspective view of the present utility model,
fig. 3 is a schematic perspective view of the present utility model.
In the figure: the sealing cover 1, the screw reinforcement 2, the grouting pipe 3, the grouting holes 4, the fins 5, the reinforcing cylinder 6, the plug 7, the screw groove 8, the slope protection plate 9 and the connecting rod 10.
Detailed Description
As shown in fig. 1 to 3, a dam slope reinforcing device of a pumped storage power station comprises a slope protection plate 9 and a plurality of reinforcing cylinders 6, wherein each reinforcing cylinder 6 is conical, a grouting pipe 3 is connected to one thinner end of each reinforcing cylinder, a conical plug 7 is arranged at one thicker end of each reinforcing cylinder 6, each grouting pipe 3 penetrates through the corresponding slope protection plate 9, a plurality of grouting holes 4 are formed in the surface of each reinforcing cylinder 6, fins 5 are fixedly connected to the outer wall of each reinforcing cylinder 6 at one end of each grouting hole, the fins 5 and the corresponding reinforcing cylinders 6 are of an integrated structure, and the maximum diameter of each plug 7 is larger than that of each reinforcing cylinder 6.
According to the utility model, when the dam slope of the power station is reinforced, the plurality of reinforcing cylinders 6 and the plugs 7 are inserted into the soil base, so that the slope protection plate 9 is tightly attached to the dam slope of the power station, the slope protection plate 9 and the reinforcing cylinders 6 can be connected in a welding mode, at the moment, the plugs 7 can be inserted into larger holes in the soil base due to the fact that the maximum diameter of the plugs 7 is larger than that of the reinforcing cylinders 6, soil can move outwards at the place where the plugs 7 pass through, cement slurry or epoxy resin is pumped into the reinforcing cylinders 6 through the grouting pipes 3, the cement slurry gradually penetrates into the soil base through the grouting holes 4, after the cement is solidified, the diameter of the plugs 7 is larger, the slope protection plate 9 can be matched with cement to limit the reinforcing cylinders 6, simultaneously, the cement overflowing out of the grouting holes 4 forms a barb anti-pulling structure in the soil body, the holding force between the reinforcing cylinders 6 and the soil body is enhanced again, the reinforcing strength of the dam slope of the power station is increased, the whole structure is simple, and the use is convenient.
The grouting device further comprises a threaded steel bar 2, one end of the threaded steel bar 2 sequentially penetrates through the grouting pipe 3 and the reinforcing cylinder 6 and then is fixedly connected with the conical plug 7, and a threaded groove 8 is formed in the conical surface of the conical plug 7. When the soil body is softer, use impact drill to press from both sides screw bar 2 one end, then by impact drill drive toper plug 7 rotation, toper plug 7 is under the drive of front end thread groove 8, bore towards the soil body depths like self tapping screw, if bore to screw bar 2 terminal length inadequately, can weld a screw bar 2, if screw bar 2 length is sufficient, can use the angle grinder to cut off unnecessary screw bar 2, take toper plug 7 to bore the back, pump cement thick liquids in to grouting pipe 3, cement thick liquids can form cement reinforcement stereoplasm district at plug 7 and reinforcement section of thick bamboo 6 like this, and cement firmly combines screw bar 2 and reinforcement section of thick bamboo 6, so make dam slope reinforcing apparatus can get up the good reinforcement effect in the soft soil body.
