Description

Technical Field

[0001] This utility model relates to the field of construction auxiliary structure technology, specifically an auxiliary structure for steel sheet pile water-stopping construction. Background Technology

[0002] Sheet piles for foundation pits are a type of structure used for foundation pit protection. They are formed by driving specific types of sheet piles into the ground to create a continuous underground wall that resists soil and water pressure, maintaining the stability of the surrounding strata. Sheet piles are steel structures with interlocking devices at their edges. These devices can be freely combined to form continuous and tight retaining or water-retaining walls. They are primarily used for foundation pit support, performing particularly well in projects such as ports, wharves, riverbank protection, retaining walls, and underground structures. Traditional sheet pile construction methods often involve using a vibratory hammer to vertically drive the sheet piles into the soil. If the vibratory hammer deviates even slightly, the sheet piles will shift, affecting their water-stopping effect. To prevent this displacement, an auxiliary structure for sheet pile water-stopping construction is proposed.

[0003] An auxiliary device for sheet pile construction, disclosed in authorization announcement number CN208121753U, includes two guide plates arranged opposite each other and multiple fixed piles. A vertical guide channel is formed between the two guide plates, and the sheet piles are arranged between the two guide plates. The fixed piles are fixed to the outer side of the guide plates, and the lower end of the fixed piles can extend into the foundation soil. The guide plates include slotted plates A and B arranged at intervals. Slotted plates A and B are connected by locking connectors. Slotted plates A and B have the same structure, each including an outer steel plate and an inner wooden board.

[0004] Although it achieves the design of two guide plates, forming a guide channel between the two guide plates, the steel sheet piles are clamped in the guide channel. During construction, the steel sheet piles are driven in with the assistance of the guide channel, which improves the neatness and verticality of the steel sheet pile retaining structure and ensures the construction quality of the steel sheet piles.

[0005] However, the existing construction auxiliary structure does not solve the problem that it is not convenient for bidirectional movement of the sheet pile during use, nor is it conducive to providing support for the sheet pile to prevent tilting and to flexibly adjust and adapt to different support contact points, thus affecting the stability of the sheet pile during construction. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary structure for water-stopping construction of sheet piles, so as to solve the problems mentioned in the background art, which are not convenient for bidirectional movement and contact limiting of sheet piles, are not conducive to providing support for sheet piles to prevent tilting, and are not flexible in adjusting and adapting to different support contact points, thus affecting the stability of sheet piles during construction.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An auxiliary structure for water-stopping construction of steel sheet piles includes an integrated frame A and mounting blocks. The integrated frames A consist of two adjacent sets connected by a connecting plate. Two sets of mounting blocks are symmetrically arranged on the outer wall of each integrated frame A, and the mounting blocks are fixedly connected to the integrated frame A. Each integrated frame A has a bidirectional threaded rod inside, and the bidirectional threaded rod is movably connected to the integrated frame A.

[0009] Optionally, an A motor is provided on each side wall of the A integrated frame, and the output end of the A motor is connected to a bidirectional lead screw.

[0010] Optionally, the surface of the bidirectional lead screw is provided with two sets of A-thread sleeves, and the A-thread sleeves are threadedly connected to the bidirectional lead screw.

[0011] Optionally, a placement plate is symmetrically arranged above the A integrated frame, and the placement plate is connected to two sets of A threaded sleeves respectively.

[0012] Optionally, each of the placement plates is provided with a B-integrated frame at its top, and the B-integrated frame is fixedly connected to the placement plate.

[0013] Optionally, each of the B integrated frames has a B lead screw movably installed inside, and each of the B integrated frames has a B motor installed at its top, with the output end of the B motor connected to the B lead screw.

[0014] Optionally, the surface of the B-lead rod is provided with a B-thread sleeve, and the B-thread sleeve is threadedly connected to the B-lead rod, and a placement frame is installed on the side wall of the B-thread sleeve.

[0015] Optionally, each of the placement frames has a drive shaft symmetrically and movably installed inside, and each drive shaft has gears fitted on its surface, with two sets of gears meshing with each other.

[0016] Optionally, drive motors are installed on the side walls of the placement frame, and the output end of the drive motor is connected to a set of drive shafts.

[0017] Optionally, an adjusting arm is mounted on the surface of the drive shaft on one side of the gear, and a limit wheel is movably mounted on the end of the adjusting arm away from the drive shaft.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the construction auxiliary structure not only realizes convenient bidirectional movement contact and limiting of steel sheet piles, which facilitates the provision of support for steel sheet piles to prevent tilting and flexibly adjusts to adapt to different support contact points, but also improves the stability of steel sheet piles during construction.

[0019] The entire device is installed at the construction location using mounting blocks. A vibratory hammer is used to grab the sheet pile and insert it between two sets of B integrated frames. The A motor drives the bidirectional lead screw to rotate, which in turn drives the two sets of A threaded sleeves to move towards each other and closer together. The A threaded sleeves, through the placement plate, drive the B integrated frames and the limiting wheels to move closer together and bring the limiting wheels into contact with the outer wall of the sheet pile, thus providing limiting support for the sheet pile from both sides. With the cooperation of four sets of adjusting arms and limiting wheels, the sheet pile is prevented from tilting during construction, thereby ensuring the construction accuracy of the sheet pile. This achieves convenient bidirectional movement and contact limiting of the sheet pile, facilitating the provision of support for the sheet pile and preventing tilting.

[0020] Motor B drives screw B to rotate, which in turn moves threaded sleeve B up and down. Threaded sleeve B then moves the placement frame, adjusting arms, and limit wheels up and down, thereby adjusting the support position of the limit wheels to facilitate support of the sheet pile from different locations. A drive motor drives a set of drive shafts to rotate, which in turn drives a set of gears. This gear set, through another set of gears, drives another set of drive shafts to rotate. The two sets of drive shafts synchronously drive two sets of adjusting arms to rotate in opposite directions, which in turn drive the limit wheels to rotate in opposite directions, moving the two sets of limit wheels away from each other. With the assistance of motor A, the contact point between the limit wheels and the sheet pile is adjusted to improve the stability of the support. This allows for flexible adjustment and adaptation to different support contact points, enhancing the stability of the sheet pile during construction. Attached Figure Description

[0035] like Figures 1 to 5 As shown, an embodiment of this utility model provides an auxiliary structure for steel sheet pile water-stopping construction, including an integrated frame A 1 and mounting blocks 13. The integrated frames A 1 are two adjacent sets, and the two sets of integrated frames A 1 are connected by a connecting plate. Two sets of mounting blocks 13 are symmetrically arranged on the outer wall of each integrated frame A 1, and the mounting blocks 13 are fixedly connected to the integrated frame A 1. A bidirectional screw rod 5 is provided inside each integrated frame A 1, and the bidirectional screw rod 5 is movably connected to the integrated frame A 1. An A motor 7 is provided on the side wall of each integrated frame A 1, which serves as a power drive, and the output end of the A motor 7 is connected to the bidirectional screw rod 5. Two sets of A threaded sleeves 6 are provided on the surface of each bidirectional screw rod 5, and the A threaded sleeves 6 are threadedly connected to the bidirectional screw rod 5.

[0036] The entire device is installed at the construction location using mounting block 13. A vibratory hammer is used to grab the sheet pile and insert it between two sets of B integrated frames 3. At this time, motor A 7 is turned on, which drives the bidirectional lead screw 5 to rotate. With the threaded connection between the bidirectional lead screw 5 and the A threaded sleeve 6, the bidirectional lead screw 5 drives the two sets of A threaded sleeves 6 to move towards each other and approach each other. The A threaded sleeve 6, through the placement plate 2, drives the B integrated frame 3 and the limiting wheel 4 to approach each other and make the limiting wheel 4 contact the outer wall of the sheet pile, thereby limiting and supporting the sheet pile from both sides. With the cooperation of the four sets of adjusting arms 12 and the limiting wheel 4, the sheet pile is prevented from tilting during construction, thus ensuring the construction accuracy of the sheet pile. It realizes convenient bidirectional movement to contact and limit the sheet pile, which facilitates the support of the sheet pile and prevents it from tilting.

[0037] A placement plate 2 is symmetrically arranged above the integrated frame 1, and the placement plate 2 is connected to two sets of threaded sleeves 6 respectively.

[0038] Each placement plate 2 has a B integrated frame 3 at its top, and the B integrated frame 3 is fixedly connected to the placement plate 2. Each B integrated frame 3 has a B lead screw 9 movably installed inside, and each B integrated frame 3 has a B motor 8 at its top. The B motor 8 serves as a power drive, and the output end of the B motor 8 is connected to the B lead screw 9.

[0039] The surface of the B-screw 9 is provided with a B-thread sleeve 10, and the B-thread sleeve 10 is threadedly connected to the B-screw 9. The side wall of the B-thread sleeve 10 is provided with a placement frame 11. The inside of the placement frame 11 is symmetrically and movably installed with a drive shaft 15. The surface of the drive shaft 15 is fitted with a gear 14, and the two sets of gears 14 mesh with each other.

[0040] A drive motor 16 is installed on the side wall of the frame 11. The drive motor 16 plays the role of power driving. The output end of the drive motor 16 is connected to a set of drive shafts 15. An adjusting arm 12 is installed on the surface of the drive shaft 15 on one side of the gear 14. A limit wheel 4 is movably installed on the end of the adjusting arm 12 away from the drive shaft 15.

[0041] Turn on motor B8, which drives lead screw B9 to rotate. With lead screw B9 threadedly connected to threaded sleeve B10, lead screw B9 drives threaded sleeve B10 to move up and down. Threaded sleeve B10 then drives the placement frame 11, adjusting arm 12, and limit wheel 4 to move up and down, thereby adjusting the support position of limit wheel 4 to facilitate support of the sheet pile from different positions. At the same time, drive motor 16 can be turned on, which drives a set of drive shafts 15 to rotate. The set of drive shafts 15 drives a set of gears 1... 4. With the meshing of two sets of gears 14, one set of gears 14 drives another set of drive shafts 15 to rotate. The two sets of drive shafts 15 synchronously drive the two sets of adjusting arms 12 to rotate in opposite directions. The adjusting arms 12 drive the limiting wheels 4 to rotate in opposite directions, so that the two sets of limiting wheels 4 move away from each other. With the cooperation of motor A 7, the contact point between the limiting wheels 4 and the sheet pile is adjusted to improve the stability of its support. This facilitates flexible adjustment and adaptation to different support contact points, and improves the stability of the sheet pile during construction.

[0042] The working principle of the technical solution provided by this utility model is as follows: The overall device is installed at the construction position through the mounting block 13. A vibratory hammer is used to grab the steel sheet pile and insert it between two sets of B integrated frames 3. The A motor 7 drives the bidirectional lead screw 5 to rotate, and the bidirectional lead screw 5 drives the two sets of A threaded sleeves 6 to move towards each other and approach each other. The A threaded sleeves 6, through the placement plate 2, drive the B integrated frame 3 and the limiting wheel 4 to move towards each other and make the limiting wheel 4 contact the outer wall of the steel sheet pile, so as to limit and support the steel sheet pile from both sides. With the cooperation of the four sets of adjusting arms 12 and the limiting wheel 4, the steel sheet pile is prevented from tilting during construction, so as to ensure the construction accuracy of the steel sheet pile. The B motor 8 drives the B lead screw 9 to rotate, and the B lead screw 9 drives the B threaded sleeve 10 to move up and down. The B threaded sleeve 10 drives the placement plate 2 to move up and down. The frame 11, adjusting arm 12, and limiting wheel 4 move up and down to adjust the support position of the limiting wheel 4, facilitating support of the sheet pile from different positions. A drive motor 16 drives a set of drive shafts 15 to rotate, which in turn drives a set of gears 14. With the meshing of the two sets of gears 14, one set of gears drives another set of drive shafts 15 to rotate. The two sets of drive shafts 15 synchronously drive the two sets of adjusting arms 12 to rotate in opposite directions, which in turn drive the limiting wheel 4 to rotate in opposite directions, thus moving the two sets of limiting wheels 4 away from each other. With the assistance of motor A 7, the contact point between the limiting wheel 4 and the sheet pile is adjusted to improve the stability of the support. This is the complete usage of the auxiliary structure used for sheet pile waterstop construction.
