Description

Technical Field

[0001] The utility model relates to the technical field of steel sheet pile construction, in particular to an auxiliary device for driving steel sheet piles. Background Art

[0002] When constructing steel sheet piles, usually the locking mouths of multiple steel sheet piles are hooked to each other and driven into the soil, and generally they are processed one by one. During the construction process, generally, a vibrating hammer on a pile driver is used to lift and strike the steel sheet piles. At the same time, during the striking, the steel sheet piles being constructed need to always remain vertical. If the operation is improper and the steel sheet piles are skewed, the skewed pile body will weaken its supporting force, making the soil prone to collapse. At the same time, the gap between piles increases, reducing the sealing performance and the water stop ability. In addition, the skewed steel sheet piles will affect the driving of subsequent piles, requiring additional adjustment and calibration, thus increasing the construction difficulty and time. Therefore, how to design an auxiliary device to ensure that the steel sheet piles are driven into the soil vertically and accurately has become a problem that needs to be solved by those skilled in the art.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model discloses an auxiliary device for steel sheet pile driving, including a fixing mechanism 1, a first steel sheet pile 3 and a second steel sheet pile 4. The first steel sheet pile 3 is a steel sheet pile that has been driven into the soil, and the second steel sheet pile 4 is a steel sheet pile that is being driven into the soil. The sides of the first steel sheet pile 3 and the second steel sheet pile 4 that are close to each other are hooked through the locking mouths. The fixing mechanism 1 includes a mounting assembly and a support assembly provided on the mounting assembly. The mounting assembly is detachably provided on the first steel sheet pile 3.

[0022] In one embodiment, the support assembly includes a plate body 16 connected to the mounting assembly, a sleeve body 17 slidably sleeved on the plate body 16, and a hook frame 18 provided on the side of the sleeve body 17 away from the plate body 16. The hook frame 18 is hooked to another locking mouth on the side of the second steel sheet pile 4 away from the first steel sheet pile 3. An adjusting device is provided on the plate body 16, and the adjusting device is used to drive the sleeve body 17 to slide and adjust on the plate body 16 and be positioned after adjustment.

[0023] In specific implementation, first, the first steel sheet pile 3 is constructed and vertically inserted into the soil. After the insertion is completed, the fixing mechanism 1 is installed on the first steel sheet pile 3 through the installation component. Since most of the first steel sheet pile 3 is in the soil after being inserted into the soil, the structure is very stable, so that the installation of the fixing mechanism 1 is also very stable. When constructing the second steel sheet pile 4, the staff hooks the lock opening on the side of the second steel sheet pile 4 away from the connection with the first steel sheet pile 3 to the hook frame 18. Immediately during the subsequent hammering process, the lock openings on both sides of the second steel sheet pile 4 are positioned by the first steel sheet pile 3 and the hook frame 18, so that the second steel sheet pile 4 can be ensured to be in a vertical state with the first steel sheet pile 3 without skewing during construction.

[0024] In one embodiment, the installation component includes an installation plate 11. Clamping plates 12 are rotatably installed on both sides of the installation plate 11. The clamping plates 12 are inclined. The side of the clamping plate 12 away from the installation plate 11 contacts the outer wall of the first steel sheet pile 3. Threaded sleeves 13 are hingedly arranged at one end of each clamping plate 12 corresponding to the installation plate 11. A lead screw 14 is arranged to pass through two corresponding threaded sleeves 13 on both sides of the installation plate 11 and is in threaded cooperation with the corresponding two threaded sleeves 13. The lead screw 14 has two threads with opposite directions at the positions corresponding to the two threaded sleeves 13. A handle 15 is installed on the lead screw 14.

[0025] In specific implementation, each threaded sleeve 13 is used to move closer to or away from each other when the lead screw 14 rotates, so that the corresponding clamping plate 12 rotates around the connection with the installation plate 11 for clamping the outer wall of the first steel sheet pile 3. When in use, the staff first places the installation component on the first steel sheet pile 3 and makes the bottom of the installation plate 11 contact the top of the first steel sheet pile 3. Subsequently, by rotating the lead screw 14, the two threaded sleeves 13 move away from each other, so that the other ends of the two clamping plates 12 away from the threaded sleeves 13 move closer to each other, and they will contact and clamp the first steel sheet pile 3, so that the installation component is very quickly and stably installed on the first steel sheet pile 3.

[0026] In one embodiment, the adjusting device is a threaded rod 19. The threaded rod 19 penetrates through the plate body 16 and extends into the sleeve body 17. The threaded rod 19 is screwed to the sleeve body 17. The threaded rod 19 is used to drive the sleeve body 17 to slide along the length direction of the plate body 16 when rotating, and the plate body 16 and the sleeve body 17 keep their relative positions unchanged when the threaded rod 19 does not rotate. The thread of the threaded rod 19 is a fine thread with self-locking property.

[0027] With such a design, the staff can adjust the combined length of the plate body 16 and the sleeve body 17 when rotating the threaded rod 19, and can also keep the plate body 16 and the sleeve body 17 at the corresponding length unchanged when not rotating the threaded rod 19. The length adjustment of the plate body 16 and the sleeve body 17 can adapt to the second steel sheet piles 4 with different widths, thus improving the applicability.

[0028] In one embodiment, a rotatable auxiliary roller 5 is installed on one side of the hook frame 18 corresponding to the second steel sheet pile 4. The rotation direction of the auxiliary roller 5 is consistent with the construction direction of the steel sheet pile, and the auxiliary roller 5 is in contact with the second steel sheet pile 4.

[0029] With such a design, when the second steel sheet pile 4 is driven into the soil, contacting with the auxiliary roller 5 can ensure higher stability during the construction process and smoother downward movement.

[0030] In one embodiment, a support assembly 2 is provided on the sleeve body 17.

[0031] In a specific implementation, the above-mentioned support assembly 2 is used to support the inwardly concave side of the second steel sheet pile 4. Cooperating with the hook frame 18 can further limit the second steel sheet pile 4, so that the second steel sheet pile 4 can only move vertically downward.

[0032] In one embodiment, the support assembly 2 includes an adjustment sleeve 21 vertically installed on the sleeve body 17, a telescopic rod 22 telescopically arranged in the adjustment sleeve 21, and a rolling ball 23 rotatably installed on the side of the telescopic rod 22 away from the adjustment sleeve 21. The adjustment sleeve 21 is screwed with the telescopic rod 22, and the rolling ball 23 is in contact with the outer wall of the steel sheet pile during driving.

[0033] With such a design, rotating the telescopic rod 22 can make it move towards or away from one end of the adjustment sleeve 21, thereby changing the combined length of the adjustment sleeve 21 and the telescopic rod 22, and making the rolling ball 23 contact the inwardly concave side of the second steel sheet pile 4. This can not only further limit the second steel sheet pile 4 to prevent construction skew, but also adapt to different sizes of the second steel sheet pile 4, thus facilitating actual use.

[0034] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0036] In addition, "a plurality of" means more than two.

[0037] The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
