When the lower slide 66 moves back and forth left and right, the two first connecting rods 68 can be used to drive the two side slides 69 to move back and forth on the inner walls of the outer shell 4 on both sides. When the lower slide 66 moves back and forth left and right, it drives the first serrated bar 67 to move synchronously. When the side slide 69 moves back and forth, it drives the second serrated bar 610 to move synchronously. The first serrated bar 67 crushes the soil blocks at the bottom of the groove. After the soil blocks are crushed, the parts protruding from the bottom of the groove enter the groove repair bucket 5, and the rest of the soil blocks remain in the soil, preventing the complete soil blocks from leaving the bottom of the groove and forming potholes. Similarly, the two second serrated bars 610 use reciprocating movement to crush the soil blocks on the walls on both sides of the groove.

[0041] Furthermore, the crushing assembly 6 also includes a motor 61, which is installed in the mounting base 2, and a rotating shaft 62 is rotatably installed in the mounting base 2.

The edge of the bevel wheel 63 is located between the two protrusions 65, and the bevel wheel 63 slides in contact with the two protrusions 65 when it rotates. After the motor 61 is started, it drives the rotating shaft 62 to rotate, and the rotating shaft 62 drives the bevel wheel 63 to rotate. When the tilted bevel wheel 63 rotates, it can use the two protrusions 65 to drive the slide rod 64 to move back and forth left and right, and the slide rod 64 drives the lower slide plate 66 to move back and forth left and right.

[0042] Furthermore, the crushing assembly 6 also includes a seesaw 611, which is rotatably mounted on the groove repair bucket 5, and two shifting rods 612 are fixedly connected to the seesaw 611. Two pull rods 613 are slidably connected to the groove repair bucket 5. One end of the two pull rods 613 is connected to the two shifting rods 612 through a sliding hinge, and a cross bar 614 is fixedly connected between the other ends of the two pull rods 613. A second connecting rod 615 is hinged on the cross bar 614. The end of the second connecting rod 615 away from the cross bar 614 is hinged to the slide bar 64. When the slide bar 64 moves back and forth left and right, the second connecting rod 615 can be used to 615 drives the cross bar 614 to move back and forth. When the two cross bars 614 move backward, the two sliding hinges and the two shift rods 612 can be used to drive the seesaw 611 to tilt upward. The tilting angle of the seesaw 611 is not greater than five degrees. The seesaw 611 can promote the movement of soil blocks into the groove repair bucket 5 by continuously tilting upward, thereby preventing the soil blocks from accumulating at the entrance of the groove repair bucket 5 after entering the groove repair bucket 5, thereby reducing the space utilization rate of the groove repair bucket 5. The seesaw 611 and the first serrated bar 67 are provided with an elastic sealing strip to prevent some soil blocks from entering under the seesaw 611 when the seesaw 611 is tilted.

[0043] In addition, the side shift assembly 7 is used to shift the soil on the shoulders of the channels on both sides to both sides; the side shift assembly 7 includes a mounting shaft 71, which is rotatably mounted in the beam frame 3, and a belt 72 is connected between the mounting shaft 71 and the rotating shaft 62 via a pulley transmission, and a worm 73 is connected to each end of the mounting shaft 71. Two short shafts 74 are rotatably mounted in the beam frame 3, and a worm gear 75 is fixedly connected to the outer wall of the short shaft 74. A first gear 76 is fixedly connected to the outer wall of the bottom of the short shaft 74. Two sets of drive wheels 77 are rotatably mounted in the beam frame 3, and one set of drive wheels 77 is provided with two, and a transmission belt 79 is respectively connected to the two sets of drive wheels 77. The outer wall of the transmission belt 79 is fixedly connected to a plurality of paddles 710, and the two worm gears 75 are respectively meshed with the two worm gears 73. A second gear 78 is fixedly connected to one of the driving wheels 77, and the second gear 78 meshes with the first gear 76. Bevels are respectively provided on both sides of the beam 3. The paddles 710 on the two transmission belts 79 protrude from the two bevels of the beam 3 respectively. A part of the paddles 710 on the two transmission belts 79 protrudes from the two bevels of the beam 3 and moves in the direction away from the rotating shaft 62 during the movement. When the beam 3 and the outer shell 4 are pushed forward, the two bevels of the beam 3 can play a guiding role, using the bevel to guide the soil blocks on the shoulders on both sides of the groove to move to the sides of the groove. The paddles 710 with protruding bevels on the two transmission belts 79 continuously paddle the soil blocks they contact to the sides of the groove during the movement, thereby promoting the soil blocks to leave the shoulders on both sides of the groove and maintain the flatness of the shoulders on both sides of the groove.

[0044] In addition, the side shift assembly 7 also includes two vibration blocks 712, both of which are slidably connected to the bottom surface of the beam 3, and the two worm gears 73 are respectively fixedly connected with cams 711, and the top surface of the vibration block 712 is fixedly connected with an arc block 713. When the two cams 711 rotate, they respectively slide in contact with the two arc blocks 713. A plurality of springs are arranged between the vibration block 712 and the beam 3. When the two worm gears 73 rotate, they respectively drive the two cams 711 to rotate. During the continuous transmission process, the two cams 711 continuously contact the two arc blocks 713, thereby driving the two vibration blocks 712 to vibrate. When vibrating, the two vibration blocks 712 can vibrate and compact the shoulders on both sides of the groove, thereby improving the density and stability of the shoulders on both sides of the groove. Example 2

[0045] A method for constructing a U-shaped water channel, using the U-shaped water channel construction equipment of Example 1, further comprising the following steps:

[0046] Step 1: Measure and lay out the lines, mark the center line of the canal and the excavation edge;

[0047] Step 2: Trench excavation: Use an excavator to dig a trench along the layout area and take precipitation measures at the same time;

[0048] Step 3: Repair the groove. The excavator is connected to the connecting seat 1, so that the outer shell 4 is close to the inner wall of the groove and drives the outer shell 4 to move. The outer shell 4 and the groove repair bucket 5 are used to repair the groove bottom and side walls.

[0049] Step 4: Pouring. After the slipform machine is installed and debugged, pour concrete continuously into the hopper starting from the starting end of the slipform machine. While the concrete is vibrated and compacted, it slides forward at a set speed and uses a mold to extrude the concrete to form a U-shaped channel.

[0050] Step 5: Maintenance: Cover the U-shaped channel with plastic film and sprinkle water regularly to ensure that the concrete strength meets the standards.

[0051] With the above structure, the working principle of this case is as follows: Figure 2As a direction reference, the connecting seat 1 can be connected to the excavator arm. After the excavator arm disassembles the bucket, the connecting seat 1 can be replaced. The connecting seat 1, the mounting seat 2, the beam 3, the outer shell 4 and the groove repair bucket 5 form a shaped bucket. The excavator drives the outer shell 4 to move into the groove so that the outer shell 4 is close to the inner side of the groove. The beam 3 is placed on the shoulders on both sides of the groove. Then the excavator moves to advance the outer shell 4 in the groove so that the groove cross-section forms a shape consistent with the cross-section of the outer shell 4. The beam 3 shapes the shoulders on both sides of the groove and plays a leveling role at the same time, which is convenient for the subsequent installation of the sliding film machine. The soil shoveled in the groove enters the groove repair bucket 5, and the excavator regularly dumps the soil in the groove repair bucket 5; the motor 61 starts The rear drive shaft 62 rotates, and the shaft 62 drives the inclined wheel 63 to rotate. When the inclined inclined wheel 63 rotates, the two protrusions 65 can be used to drive the slide bar 64 to move back and forth left and right. The slide bar 64 drives the lower slide plate 66 to move back and forth left and right. When the lower slide plate 66 moves back and forth left and right, the two first connecting rods 68 can be used to drive the two side slide plates 69 to move back and forth on the inner walls of both sides of the outer shell 4. When the lower slide plate 66 moves back and forth left and right, it drives the first sawtooth bar 67 to move synchronously. When the side slide plate 69 moves back and forth, it drives the second sawtooth bar 610 to move synchronously. The first sawtooth bar 67 and the two second sawtooth bars 610 can contact the inner side of the groove during the advancement of the outer shell 4. The first sawtooth bar 67 contacts the bottom of the groove. The soil blocks on the upper part of the groove are crushed. When the first sawtooth bar 67 contacts the soil blocks, the first sawtooth bar 67 uses reciprocating movement to crush the sawtooth bar. After the soil blocks are crushed, the part protruding from the bottom of the groove enters the groove repair bucket 5, and the rest of the soil blocks remain in the soil, avoiding the complete soil blocks from leaving the bottom of the groove and forming pits. Similarly, the two second sawtooth bars 610 use reciprocating movement to crush the soil blocks on the two side walls of the groove, avoiding the formation of pits on the side walls of the groove; the two pull rods 613 are limited by the groove repair bucket 5 and can only move back and forth. When the sliding bar 64 moves back and forth, the second connecting rod 615 can be used to drive the cross bar 614 to move back and forth, and the cross bar 614 drives the two pull rods 613 to move back and forth. The two cross bars 614 move back and forth, and when they move backward, the two sliding hinges and the two shifting rods 612 can be used to drive the seesaw 611 to tilt upward. The tilting angle of the seesaw 611 is not greater than five degrees. After the soil blocks enter the groove repair bucket 5, they first move onto the seesaw 611. The seesaw 611 can promote the movement of the soil blocks into the interior of the groove repair bucket 5 by continuously tilting upward, thereby preventing the soil blocks from accumulating at the entrance of the groove repair bucket 5 after entering the groove repair bucket 5, resulting in excessive accumulation of soil blocks at the entrance of the groove repair bucket 5 and less accumulation of soil blocks inside the groove repair bucket 5, thereby reducing the space utilization rate of the groove repair bucket 5. The seesaw 611 and the first serrated bar 67 are provided with elastic sealing strips to prevent some soil blocks from entering under the seesaw 611 when the seesaw 611 tilts.

[0052] The rotating shaft 62 drives the installation shaft 71 to rotate through the belt 72, and the installation shaft 71 drives the two worm gears 75 to rotate through the two worm gears 73. The two worm gears 75 respectively drive the two short shafts 74 to rotate. The two short shafts 74 respectively drive the two second gears 78 to rotate through the two first gears 76. When the two second gears 78 rotate, they respectively drive the two transmission belts 79 to rotate through the two sets of driving wheels 77. When the transmission belts 79 rotate, they drive the multiple paddles 710 above them to rotate. The paddles 710 on the two transmission belts 79 protrude from the two oblique sides of the beam frame 3 and move in the direction away from the rotating shaft 62 during the movement. When the beam frame 3 and the outer shell 4 are pushed forward, the two oblique sides of the beam frame 3 can play a guiding role, using the oblique surface to guide the soil blocks on the shoulders on both sides of the groove to move to both sides of the groove. The paddles 710 protruding from the oblique sides of the two transmission belts 79 are During the movement, the soil blocks it contacts are continuously pushed to the sides of the groove, promoting the soil blocks to leave the shoulders on both sides of the groove and maintaining the flatness of the shoulders on both sides of the groove; when the two worm gears 73 rotate, they respectively drive the two cams 711 to rotate, and each time the two cams 711 rotate one circle, they respectively contact and drive the two arc blocks 713 to move downward, and when the arc block 713 moves downward, it drives the vibration block 712 to move downward, and when the arc block 713 is no longer in contact with the cam 711, the vibration block 712 uses the elastic force of multiple springs to reset, and the arc block 713 is also reset accordingly. The continuous downward movement and reset of the vibration block 712 can be regarded as vibration. Therefore, when the two worm gears 73 continue to rotate, the two vibration blocks 712 can continuously generate vibration. When vibrating, the two vibration blocks 712 can vibrate and compact the shoulders on both sides of the groove, thereby improving the density and stability of the shoulders on both sides of the groove.
