Description

Technical Field

[0001] The present invention relates to the technical field of dam core wall construction, and particularly to a filling and rolling device for the construction of a dam core wall impervious body and a usage method thereof. Background Technique

[0002] An impervious wall is a diaphragm wall built in a loose pervious layer or an earth-rock dam (weir) to play an impervious role. The impervious wall technology originated in Europe in the 1950s. Due to its reliable structure, good impervious effect, adaptability to various stratum conditions, simple construction, and low cost, especially in dealing with problems such as dam foundation leakage, "flowing soil" and "piping" behind the dam and other seepage deformation hidden dangers, it has been widely used at home and abroad. For the impervious treatment of water conservancy and hydropower overburden and earth-rock cofferdams with impervious pressure in China, the impervious wall is generally the first choice.

[0003] The existing rolling device can flatten and roll the dam core wall by using the rolling wheel. However, its disadvantage is that the function is relatively single. Before rolling the impervious core wall, it needs to be filled, but filling requires another filling machine, which increases the cost of the construction of the dam core wall impervious body.

Detailed implementation manner

[0046] Such as Figures 1 - 7Among them, a filling and rolling device for the construction of the anti-seepage body of a dam core wall includes an installation frame 1 and an adjustment component 2. A rolling component 3 is provided at the lower part of the adjustment component 2. A filling component 4 and a driving component 6 are respectively arranged on both sides of the rolling component 3. A sealing component 5 is provided on one side of the rolling component 3 close to the adjustment component 2. The rolling component 3 includes a connecting seat 301 and a fixed cover 302. A rolling roller 303 is rotatably arranged in the fixed cover 302. An inner cylinder 304 is provided on the inner wall of the rolling roller 303. The filling component 4 includes a screw rod 404, and the screw rod 404 is located in the inner cylinder 304. The overall shape of the fixed cover 302 is arc-shaped, and the inner wall of the fixed cover 302 is in close contact with the outer wall of the rolling roller 303. With this structure, the driving component 6 provides power for the rolling component 3. The screw rod 404 in the filling component 4 fully mixes the soil material. The inner cylinder 304 stores the soil material temporarily and can provide a certain weight for the rolling component 3, making the overall compaction effect better. Pour the soil material from the feed hopper 407 into the rolling roller 303, start the second motor 401 to drive the screw rod 404 to rotate, and convey the soil material into the rolling roller 303. Since a discharge port 405 is opened at the bottom of the rolling roller 303, the soil material is conveyed onto the dam core wall, which is convenient for filling the dam core wall. It has strong applicability when encountering structures such as water discharge culverts and pump houses during the dam filling process. Especially when the traditional roller is limited in filling and rolling construction in a narrow space, it can play a certain role. By controlling the distance between this filling and rolling device and the dam core wall, the layered filling thickness can be controlled. When the inner wall of the fixed cover 302 is in contact with the outside of the rolling roller 303 and the outer wall of the rolling roller 303 is stained with soil during rolling, the fixed cover 302 can be used to clean the soil adhered to the outside of the rolling roller 303, so as to facilitate the rolling of the rolling roller 303 on the soil.

[0047] In the preferred solution, the adjustment component 2 includes a connecting plate 201. An adjustment port 205 is provided on one side of the connecting plate 201. A first motor 203 is provided outside the adjustment port 205. The first motor 203 is connected to the connecting plate 201 through a connecting block 202. The connecting block 202 is located in the adjustment port 205. A cylinder 204 is provided on the connecting block 202. The connecting seat 301 is fixed at the end of the cylinder 204. With this structure, the angle of the cylinder 204 can be adjusted through the first motor 203, so that the rolling component 3 mounted on the cylinder 204 fits better on the ground, ensuring the stable contact state between the rolling roller 303 and the ground, more uniform force, and more stable support.

[0048] In a preferred embodiment, the filling assembly 4 includes a second motor 401, a frame 402, and a feed hopper 407. The frame 402 is fixed to the end of the rolling roller 303. The second motor 401 is connected to a screw rod 404 through a bearing 403. A feed hopper 407 and a notch 406 for cooperating with the filling assembly 4 to work are respectively provided on the upper and lower sides of the rolling roller 303. A plurality of discharge ports 405 are provided inside the notch 406, and the plurality of discharge ports 405 uniformly penetrate through the inner cylinder 304. With this structure, soil is poured from the feed hopper 407 into the rolling roller 303. The second motor 401 is started to drive the screw rod 404 to rotate, and the soil is conveyed into the rolling roller 303. Since the discharge port 405 is provided at the bottom of the rolling roller 303, the soil is conveyed to the core wall of the dam, facilitating the filling of the core wall of the dam.

[0049] In a preferred embodiment, the sealing assembly 5 includes a placement groove 501 provided in the upper part of the inner cavity of the fixed cover 302 and a second electromagnet 507 and a second electric base 508 provided at the bottom of the inner cylinder 304. A first electromagnet 502 and an iron plate 503 are provided on the upper part of the inner side wall of the placement groove 501. The sealing assembly 5 further includes a first electric base 504. The first electric base 504 is fixedly provided on the front side of the connecting seat 301. A first control button 505 and a first wire 506 are provided on the first electric base 504. A second wire 509 and a second control button 510 are provided on the second electric base 508;

[0050] The second control button 510 is used to control the opening and closing of the second electromagnet 507, and the first control button 505 is used to control the opening and closing of the first electromagnet 502. The first wire 506 is electrically connected to the first electromagnet 502, and the second wire 509 is electrically connected to the second electromagnet 507. The shape and size of the iron plate 503 are adapted to the shape of the notch 406 at the bottom of the rolling roller 303. With this structure, the suction states of the first electromagnet 502 and the second electromagnet 507 can be respectively switched through the first control button 505 and the second control button 510 in the sealing assembly 5, so as to cooperate with the cylinder 304, thereby adjusting the position of the iron plate 503 and ensuring the coordinated switching of the filling function and the rolling function.

[0051] In a preferred solution, the driving assembly 6 includes a third motor 601, a rotating shaft 603 and a chain 605. The third motor 601 is fixedly arranged on the top of the fixed cover 302, the rotating shaft 603 is fixedly arranged outside the rolling roller 303. Sprockets 604 are respectively arranged on the third motor 601 and the rotating shaft 603, and the two sprockets 604 are connected by the chain 605. The driving assembly 6 further includes a protective cover 602, and the protective cover 602 is arranged outside the rolling roller 303. With this structure, the operation of the third motor 601 drives the rolling roller 303 to rotate in the fixed cover 302 through the chain 605 and the sprockets 604, moving the notch 406 on the rolling roller 303 directly below the iron plate 503. The second electromagnet 507 is energized by using the second control button 510, and the second electromagnet 507 generates magnetic force. The first electromagnet 502 is controlled to be de-energized by using the first control button 505, so that the first electromagnet 502 has no magnetic force. At this time, the second electromagnet 507 adsorbs the iron plate 503 to block the discharge port 405, making the iron plate 503 and the rolling roller 303 form a complete cylinder. The rolling roller 303 is driven to move by the mobile machinery, and the rolling roller 303 is rotated by the rotation of the third motor 601, facilitating the compaction of the dam core wall after filling.

[0052] As Figures 8 - 16 In the preferred solution, a plurality of bosses 305 are arranged on one side of the fixed cover 302 close to the adjusting assembly 2. A telescopic unit 8 is arranged on the boss 305 in the middle, and a limit seat 11 is arranged on the bosses 305 on both sides. A push bucket 9 is arranged at the bottom of the telescopic unit 8. Round rods 905 are symmetrically arranged on the push bucket 9, and the round rods 905 are slidably connected with the limit seats 11. With this structure, when the soil material falls to the ground from the discharge port 405, the telescopic unit 8 can be used to lower the push bucket 9, thereby completing the paving of the soil material, ensuring that the height of each layer is within the design tolerance range, and ensuring high strength and good construction quality of the core wall.

[0053] In the preferred solution, a first threaded hole 306 is arranged on the boss 305. The telescopic unit 8 includes a first L-shaped plate 801 and a cylinder body 802. A first waist-shaped slot 804 is arranged on the first L-shaped plate 801. A ejector rod 803 is arranged on the cylinder body 802. The push bucket 9 is fixedly arranged at the end of the ejector rod 803. The limit seat 11 includes a second L-shaped plate 1101 and a sleeve 1102. A second waist-shaped slot 1103 is arranged on the second L-shaped plate 1101. The round rod 905 is arranged inside the sleeve 1102, and screws 10 are respectively arranged in the first waist-shaped slot 804 and the second waist-shaped slot 1103;

[0054] A fixed pulley 12 is provided at the bottom of the boss 305. T-shaped sliding grooves 307 are respectively provided on both sides of the fixed cover 302.

The slider 13 adopts an outer shape structure that matches the T-shaped sliding groove 307. A connection hole for locking and fixing in cooperation with the clamping plate 906 is provided on the slider 13. Due to the action of the ejector rod 803, the pushing bucket 9 is driven to move, thereby driving the clamping plate 906 to drive the slider 13 to move. With the aid of the fixed pulley 12, the auxiliary plate 15 is pulled out from the upper part of the pushing bucket 9 through the fixed cable 14. The auxiliary plate 15 is a straight plate, and the plane on the straight plate cooperates with the pushing bucket 9 to form a larger range of earth material blocking effect, ensuring stable paving effect and large paving volume.

[0055] In a preferred solution, a plurality of sliding grooves 16 are provided on the auxiliary plate 15. A contact arc surface 902 is provided on one side of the movable plate 901.

The contact arc surface 902 has a better cutting angle on the side close to the ground to complete the pushing effect of the earth material, while the straight surface of the auxiliary plate 15 can effectively block the earth material far from the ground, preventing the earth material from leaking out from the gap between the pushing bucket 9 and the fixed cover 302, affecting the paving effect and paving efficiency.

[0056] As Figures 17 - 20 In [reference], in a preferred solution, a plurality of through holes 408 are provided along the circumferential direction on the screw rod 404. A support rod 17 is inserted into the through holes 408. A separation unit 18 is provided on the support rod 17. Threaded heads 1701 are respectively provided on both sides of the support rod 17.

The partition rod 1803 includes a vertical rod 1809. The vertical rod 1809 is threadedly connected with the third threaded holes 1804. A plurality of cross rods 1810 are arranged in parallel on the vertical rod 1809. The direction of the cross rods 1810 is consistent with the axis of the screw rod 404. With this structure, the screw rod 404 is used as the rotating main body to drive the separation unit 18 to work. The cutting disc 1802 further spaces the spiral blades on the screw rod 404. When conveying the soil material, the easily adhesive soil material can be cut and separated. Cooperating with the cross rods 1810, the original soil material is disrupted, ensuring that the soil material does not agglomerate and block, affecting the effect during filling, and avoiding restrictions on subsequent work.

[0058] In a preferred solution, a method for using a filling and rolling device includes the following steps:

[0059] S1. Use the mounting holes 7 on the mounting frame 1 to mount the mounting frame 1 on an external mobile machine, and connect the first motor 203, the second motor 401, the third motor 601, the first electric wire 506, and the second electric wire 509 to an external power source;

[0060] S2. According to the slope angle of the core wall of the dam, start the first motor 203 to drive the connecting block 202 and the air cylinder 204, thereby driving the rolling assembly 3 to rotate, and adjust the rolling roller 303 and the fixed cover 302 to a position parallel to the slope angle;

[0061] S3. When it is necessary to fill the core wall of the dam, pour the soil from the feed hopper 407 into the rolling roller 303, start the second motor 401 to drive the screw rod 404 to rotate, and convey the soil to the rolling roller 303. Since a discharge port 405 is opened at the bottom of the rolling roller 303, the soil is conveyed to the core wall of the dam for filling the core wall of the dam. Adjust the state of the pushing hopper 9 as needed, thereby cooperating with the filling assembly 4 to complete the paving work of the soil material;

[0062] S4.
