Technical Field

[0001] The present application relates to the technical field of piling in cofferdam construction, and in particular to a piling auxiliary device in cofferdam construction. Background Art

[0002] Cofferdam refers to a temporary enclosure structure built in the construction of permanent water conservancy facilities during water conservancy project construction. Its function is to prevent water and soil from entering the construction site of the building so that drainage can be done in the cofferdam, foundation pits can be excavated, and buildings can be built. It is generally used in river projects and hydraulic structures. Except as part of a formal building, the cofferdam is generally dismantled after use; the height of the cofferdam is higher than the highest water level that may occur during the construction period.

[0003] At present, the usual construction method of combined pile formwork cofferdam is to use an excavator modified into a pile driver to drive H-shaped steel into the riverbed one by one as a pile formwork, and then insert the fixed steel formwork into the groove between the H-shaped steel wing plates. After the cofferdam is formed, waterproof cloth is used on the water-facing surface to prevent seepage, and the back water surface is reinforced with scaffolding pipe frames and diagonal braces.

[0004] However, during the construction phase, it was found that there were certain safety hazards when workers supported the piles under the pile driver, and the distance, verticality and positioning between the piles could not be effectively controlled, resulting in a high rework rate, which affected the construction speed. Therefore, those skilled in the art provided a pile driving auxiliary device in cofferdam construction to solve the problems raised in the above background technology. Utility Model Content

[0009] The support blocks are provided in two groups, and the two groups of support blocks are respectively arranged on the side away from each other of the two groups of top blocks. Reinforcement devices are arranged on both sides of the two groups of support blocks, and pile foundations are attached to the side away from the top blocks of the two groups of support blocks.

[0010] In some embodiments, both ends of the auxiliary frame column are fixedly connected to limit rings, and two groups of limit rings are respectively sleeved on the surfaces of the two groups of top blocks.

[0011] In some embodiments, the reinforcement device includes a slider sliding inside the top block, and the slider is provided in two groups. One side of the two groups of sliders is fixedly connected to a top plate, and a limit block is provided inside the top plate for sliding. The limit block is close to the side of the support block and fits with the pile foundation.

[0012] In some embodiments, the two groups of top blocks are symmetrically threaded with first fixing bolts on one side close to the auxiliary frame column, and one end of the first fixing bolt symmetrically passes through the top block and fits against the outer wall of the sliding block.

[0013] In some embodiments, rollers are fixedly connected to the sides of the two groups of top plates that are close to each other, and a plurality of rollers are provided, and one side of the plurality of rollers is in contact with the outer wall of the pile foundation.

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The present application embodiment discloses a piling auxiliary device in cofferdam construction. Figure 1-4 A piling auxiliary device in cofferdam construction comprises an auxiliary frame column 1, a threaded shaft 4 and a support block 6, one side of the auxiliary frame column 1 is fixedly connected with a motor 2, one side output end of the motor 2 is fixedly connected with a transmission plate 3 through a coupling, the threaded shaft 4 is rotatably arranged inside the auxiliary frame column 1, one side of the transmission plate 3 is sleeved on the surface of the threaded shaft 4, both ends of the threaded shaft 4 are threadedly plugged with top blocks 5, two groups of the top blocks 5 are located inside the auxiliary frame column 1 and slide, and two groups of support blocks 6 are arranged, and the two groups of support blocks 6 are respectively arranged on the side away from each other of the two groups of top blocks 5, and reinforcement devices 8 are arranged on both sides of the two groups of support blocks 6, and pile foundations 7 are attached to the side away from the top blocks 5 of the two groups of support blocks 6;

[0025] In this way, during the implementation process, when it is necessary to drive the pile foundation 7, the staff suspends the pile foundation 7 on the sea surface through a crane, and then vertically inserts the pile foundation 7 into the water. The distance between several pile foundations 7 needs to be limited to avoid the pile foundation 7 from being skewed during the pile driving process. The worker suspends the auxiliary frame column 1 between the two groups of pile foundations 7, and the staff starts the motor 2. The motor 2 will drive the transmission disc 3 to rotate, and the transmission disc 3 will drive the threaded shaft 4 inside the auxiliary frame column 1 to rotate. During the rotation of the threaded shaft 4, the top blocks 5 at both ends will be pushed to slide to the side away from each other, and the top block 5 drives one side of the support block 6 to fit the outer wall of the pile foundation 7. The support of the pile foundation 7 by the top block 5 improves the controllability of the distance between the two groups of pile foundations 7.

[0026] During the process of fitting the support block 6 with the pile foundation 7, the staff will place the reinforcement device 8 on both sides of the pile foundation 7, so that the support block 6 can limit the pile foundation 7 through the reinforcement devices 8 on both sides, so that the two groups of pile foundations 7 will not tilt to both sides, thereby increasing the stability between the two groups of pile foundations 7, and then use a pile driver to drive the pile foundation 7 to increase the controllability of multiple pile foundations 7 when inserted into the soil.

[0027] Among them, both ends of the auxiliary frame column 1 are fixedly connected with limiting rings 11, and the two groups of limiting rings 11 are respectively sleeved on the surfaces of the two groups of top blocks 5. The outer walls of the limiting rings 11 are fixed to the inner walls of the auxiliary frame column 1. When the top block 5 is located inside the auxiliary frame column 1 and slides, the limiting rings 11 will limit the position of the top block 5, so that the sliding distance of the top block 5 inside the auxiliary frame column 1 can be controlled, thereby increasing safety.

[0028] Preferably, the reinforcement device 8 comprises a slider 81 which slides inside the top block 5, and two groups of the sliders 81 are provided. One side of the two groups of sliders 81 is fixedly connected with a top plate 83, and a limit block 86 is provided inside the top plate 83 for sliding. The limit block 86 is close to the side of the support block 6 and fits with the pile foundation 7.

[0029] The slider 81 is located inside the top block 5 and slides to control the distance between the top plate 83 and the support block 6, so that the top plate 83 can fit better with the pile foundation 7, and the stability between the pile foundation 7 and the support block 6 is increased. The sliding of the limit block 86 can fit the inside of the pile foundation 7, and the pile foundation 7 is restricted on one side away from the support block 6, so that one side of the support block 6 can fit better with the pile foundation 7.

[0030] Specifically, the two groups of top blocks 5 are symmetrically threaded with first fixing bolts 82 on one side close to the auxiliary frame column 1, and one end of the first fixing bolt 82 symmetrically passes through the top block 5 and fits against the outer wall of the sliding block 81;

[0031] After the slider 81 is fixed inside the top block 5, the worker turns the first fixing bolt 82 to fit the slider 81 so that the slider 81 abuts against the inner wall of the top block 5, fixes the slider 81 inside the top block 5, and increases the stability of the top plate 83 limiting the pile foundation 7.

[0032] More specifically, a roller 87 is fixedly connected to one side of the two groups of top plates 83 that are close to each other, and a plurality of rollers 87 are provided, and one side of the plurality of rollers 87 is in contact with the outer wall of the pile foundation 7;

[0033] The plurality of rollers 87 support the pile foundation 7 , so that the top plate 83 can slide horizontally on both sides of the pile foundation 7 , which facilitates the change of the position of the top plate 83 . The rollers 87 can reduce the friction between the top plate 83 and the pile foundation 7 .

[0034] Further in the implementation process, the two groups of top plates 83 are fixedly connected to the side away from each other with a limit housing 84, and a slide bar 85 is slidably provided inside the limit housing 84, and one end of the slide bar 85 is fixedly connected to the outer wall of the limit block 86, and a second fixing bolt 841 is threadedly inserted into the outer wall of the limit housing 84 near the limit block 86, and one end of the second fixing bolt 841 passes through the limit housing 84 and fits the outer wall of the slide bar 85;

[0035] The limiting shell 84 limits the sliding rod 85, so that the sliding rod 85 slides relatively horizontally along one side of the top plate 83. During the sliding process, the sliding rod 85 drives the limiting block 86 to slide inside the top plate 83. By adjusting the position of the limiting block 86, the distance between the limiting block 86 and the supporting block 6 can be changed, so that the pile foundation 7 can be better limited. The limiting shell 84 limits the sliding rod 85 through the second fixing bolt 841, and the sliding rod 85 pulls the limiting block 86 to change its position, thereby increasing the stability of the limiting block 86 inside the top plate 83.

[0036] The implementation principle of the piling auxiliary device in the cofferdam construction of the embodiment of the present application is as follows: when the pile foundation 7 needs to be piled, the worker suspends the pile foundation 7 on the sea surface by a crane, and then vertically inserts the pile foundation 7 into the water. The distance between several pile foundations 7 needs to be limited to avoid the pile foundation 7 from tilting during the piling process. The worker suspends the auxiliary frame column 1 between two groups of pile foundations 7, and the worker starts the motor 2. The motor 2 drives the transmission disk 3 to rotate, and the transmission disk 3 drives the threaded shaft 4 inside the auxiliary frame column 1 to rotate. During the rotation of the threaded shaft 4, it pushes the two ends The top block 5 slides to the side away from each other, and the top block 5 drives one side of the support block 6 to fit the outer wall of the pile foundation 7. The support of the pile foundation 7 by the top block 5 improves the controllability of the distance between the two groups of pile foundations 7. During the process of the support block 6 fitting with the pile foundation 7, the staff will place the reinforcement device 8 on both sides of the pile foundation 7, so that the support block 6 limits the pile foundation 7 through the reinforcement devices 8 on both sides, so that the two groups of pile foundations 7 will not tilt to both sides, thereby increasing the stability between the two groups of pile foundations 7, and then the pile driver will drive the pile foundation 7 to increase the controllability of the multiple pile foundations 7 inserted into the soil.
