Description

Technical Field

[0001] The invention relates to the technical field of underwater island construction platform construction, and in particular to an underwater island construction platform filling and compacting device and method thereof. Background Art

[0002] An underwater island platform is a temporary or permanent island formed by filling materials in a river, lake or other water body, used for the construction of bridges, docks or other water structures.

[0003] In the prior art, when constructing an underwater island platform, it is necessary to build a bottom foundation on the bottom of the water, and then build the island platform on the bottom foundation. In the prior art, when constructing the bottom foundation, a fence is first set up on the bottom of the water, and then concrete is poured into the fence through a pouring pipe to form a foundation. However, during the construction process, most of the concrete will accumulate at the lower end of the pouring pipe, and the pouring pipe can only be moved continuously to disperse the concrete. However, in the actual construction process, on the one hand, the pouring pipe is too long and inconvenient to move horizontally, and on the other hand, even if the pouring pipe is continuously moved, it is difficult to fill the concrete to the edge of the fence. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art and to propose a filling and compacting device for an underwater island building platform, thereby solving the problems existing in the prior art.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A filling and compacting device for an underwater island platform comprises a grouting pipe, an enclosure and a cover plate. The grouting pipe is located at the center of the enclosure. A group of cross beams are evenly and fixedly connected to the outside of the grouting pipe. The other end of each cross beam is fixed to the inner wall of the enclosure. The cover plate is arranged in the enclosure and placed on the upper side of the cross beam. A group of mounting grooves are arranged at the bottom of the grouting pipe. Each mounting groove is rotatably connected to a swing rod through a rotating rod. A group of lifting devices are evenly arranged on the outer wall of the bottom of the grouting pipe. A pressure rod is arranged in the grouting pipe. The lower end of the pressure rod is fixedly connected to the pressure plate. One end of the swing rod is located below the pressure plate. When the pressure plate moves downward, the swing rod rotates and causes the jacking device to push the cover plate upward.

[0007] Preferably, a tapered transition section is provided between the pressure plate and the pressure rod.

[0008] Preferably, the lifting device includes a mounting plate, which is fixed on the outer wall of the perfusion pipe. The mounting plate is slidably connected to a vertically arranged guide rod, the lower end of the guide rod is fixedly connected to a resistance plate, a first spring is fixedly connected between the resistance plate and the mounting plate, and a clearance groove is provided on the cross beam, and the guide rod can pass through the clearance groove.

[0009] Preferably, the lower side of the contact plate is an arc surface, and the arc surface is in contact with the swing rod.

[0010] Preferably, a bracket is fixedly connected to the inner wall of the enclosure, the bracket is rotatably connected to a rotating shaft, both ends of the rotating shaft are fixedly connected to mounting shafts, a plurality of flat plates are evenly fixedly connected to the mounting shaft, and a driving device is installed on the crossbeam, which is used to drive the rotating shaft to rotate.

[0011] Preferably, the driving device includes a slide rod, which slides back and forth in a slide groove on the lower side of the crossbeam, a second spring is fixedly connected between one side of the slide groove and the slide rod, a straight ratchet bar is installed on the slide rod, a ratchet wheel is installed on the rotating shaft, and the straight ratchet bar matches the ratchet wheel.

[0012] Preferably, one side of the guide rod is fixedly connected to the mounting plate, and one side of the mounting plate is provided with an inclined surface. When the guide rod drives the mounting plate to rise, the inclined surface contacts one end of the slide rod, thereby causing the slide rod to move horizontally.

[0013] The advantages of the present invention are as follows: the filling and compacting device for an underwater island building platform provided by the present invention moves the guide rod upward by moving the pressing plate downward, and pushes the cover plate upward, so that water waves can be formed on the lower side of the cover plate. During the up and down movement of the pressing plate, the concrete accumulated under the pouring pipe can be squeezed toward the surroundings. At the same time, the water waves formed on the lower side of the cover plate provide assistance to the concrete to move toward the surroundings, thereby improving the effect of the concrete moving toward the surroundings.

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Example 1

[0021] like Figure 1-Figure 5As shown, this embodiment discloses a filling and compacting device for an underwater island platform, including a perfusion pipe 1, an enclosure 200, and a cover plate 300. The perfusion pipe 1 is located at the center of the enclosure 200, and a group of beams 4 are evenly fixedly connected to the outside of the perfusion pipe 1. The other end of each beam 4 is fixed on the inner wall of the enclosure 200. The cover plate 300 is arranged in the enclosure 200 and is placed on the upper side of the beam 4. The cover plate 300 can slide back and forth up and down along the inner wall of the enclosure 200, and a plurality of water-permeable openings 400 are provided at the edge of the cover plate 300.

[0022] Four mounting grooves 12 are provided at the bottom of the perfusion pipe 1. Each mounting groove 12 is rotatably connected to the swing rod 6 through a rotating rod 61. Four lifting devices 7 are evenly provided on the outer wall of the bottom of the perfusion pipe 1. The four lifting devices 7 are arranged in the four mounting grooves 12 in a one-to-one correspondence. The lifting device 7 includes a mounting plate 71. The mounting plate 71 is fixed on the outer wall of the perfusion pipe 1. The mounting plate 71 is provided with a sliding hole. A vertically arranged guide rod 72 is slidably connected in the sliding hole. The lower end of the guide rod 72 is fixedly connected to a contact plate 73. The lower side of the contact plate 73 is an arc surface, and the arc surface contacts the swing rod 6. A first spring 74 is fixedly connected between the contact plate 73 and the mounting plate 71. The guide rod 72 passes through the inner circle of the first spring 74. A clearance groove 41 is provided on the crossbeam 4. The guide rod 72 can pass through the clearance groove 41.

[0023] A pressing rod 2 is provided in the injection pipe 1, and the lower end of the pressing rod 2 is fixedly connected to a pressing plate 3, and a tapered transition section 31 is provided between the pressing plate 3 and the pressing rod 2. The tapered transition section 31 can improve the strength of the pressing plate 3 and prevent the pressing plate 3 from being deformed during operation. At the same time, the diameter of the pressing plate 3 is smaller than the inner diameter of the injection pipe 1, that is, there is a gap between the pressing plate 3 and the inner wall of the injection pipe 1, so that concrete can enter the enclosure 200 from the gap, and the tapered transition section 31 can guide the concrete, and the concrete enters from all sides of the pressing plate 3, which can also avoid concrete accumulation to a certain extent.

[0024] At the same time, one end of the swing rod 6 is arranged below the pressing plate 3. When the pressing plate 3 moves downward, the swing rod 6 rotates and causes the guide rod 72 to move upward, thereby pushing the cover plate 300 to move upward. During the upward movement of the cover plate 300, the water on the upper side of the cover plate 300 will enter the lower side of the cover plate 300 through the water-permeable opening 400, so that water waves can be formed on the lower side of the cover plate 300. The pressing plate 3 continues to move downward. During the up and down movement of the pressing plate 3, the concrete accumulated under the pouring pipe 1 can be squeezed toward the surrounding area. At the same time, the water waves formed on the lower side of the cover plate 300 provide assistance for the concrete to move toward the surrounding area, thereby further improving the effect of the concrete moving toward the surrounding area.

[0025] Example 2

[0026] On the basis of Example 1, in order to increase the wave force, a bracket 91 is fixedly connected to the inner wall of the enclosure 200, a rotating shaft 92 is rotatably connected to the bracket 91, both ends of the rotating shaft 92 are fixedly connected to the mounting shaft 93, a plurality of flat plates 94 are evenly fixedly connected to the mounting shaft 93, and a driving device is installed on the crossbeam 4, and the driving device is used to drive the rotating shaft 92 to rotate. During the rotation of the rotating shaft 92, the mounting shaft 93 and the flat plates 94 on its outer side will also rotate, thereby generating disturbances on the water, and the wave force can be increased under this disturbance force, thereby increasing the assistance to the movement of the concrete, and further improving the effect of the concrete moving to the surrounding.

[0027] Due to the underwater operation, in order to prevent the live equipment from entering the water, the present embodiment has a special design for the driving device, which is as follows: the driving device includes a slide bar 5, which slides back and forth in the slide groove on the lower side of the cross beam 4, and a second spring 52 is fixedly connected between one side of the slide groove and the slide bar 5, and a straight ratchet bar 51 is installed on the slide bar 5, and a ratchet 95 is installed on the rotating shaft 92, and the straight ratchet bar 51 matches the ratchet 95. The straight ratchet bar 51 and the ratchet 95 are prior art and will not be described here. The horizontal reciprocating movement of the straight ratchet bar 51 can make the ratchet 95 intermittently rotate in one direction. One side of the guide rod 72 is fixedly connected to the mounting plate 8, and one side of the mounting plate 8 is provided with an inclined surface 81. When the guide rod 72 drives the mounting plate 8 to rise, the inclined surface 81 contacts one end of the slide bar 5, thereby causing the slide bar 5 to move horizontally. With such a setting, there is no need for the live equipment to enter the water, and it is only necessary to provide a longitudinal push-pull force to the pressure rod 2 from above the water surface.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
