Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a U-shaped sheet pile guide frame. Background Technology

[0002] Sheet pile guide frames play a crucial role in engineering construction, ensuring the accuracy and quality of sheet pile installation. Early guide frames were typically constructed from wood or simple metal components, resulting in a crude design and relatively limited function. Their primary purpose was to provide basic insertion guidance for the sheet piles, improving installation accuracy and efficiency to some extent, but they lacked stability and versatility.

[0003] As the scale of construction projects gradually expands and the requirements for construction precision increase, the design of guide frames is becoming increasingly diversified. However, there are still many shortcomings, such as the inability to guarantee the horizontal accuracy of the guide frame when encountering complex construction sites with varying heights or underwater construction sites; the guide frame itself is relatively bulky and difficult to move; during sheet pile construction, insufficient vertical accuracy makes it easy for the guide frame to wear and damage the sheet piles. Utility Model Content

[0004] In view of the technical problems existing in the prior art, the purpose of this utility model is to provide a U-shaped sheet pile guide frame to solve the problem that the existing guide frame cannot guarantee the horizontal accuracy when encountering complex construction sites with varying heights and underwater construction sites.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A U-shaped sheet pile guide frame includes two main poles and two transverse telescopic poles. The two main poles are spaced apart. The two ends of one transverse telescopic pole are connected to one end of each of the two main poles, and the two ends of the other transverse telescopic pole are connected to the other ends of each of the two main poles, forming a rectangular frame. Telescopic brackets are connected to the connection points of the transverse telescopic poles and the main poles. A circular level is installed on each main pole. A hydraulic device is installed on one side of each of the two main poles. The hydraulic device is equipped with ball bearings. A controller is installed on the main pole. The telescopic brackets are electrically connected to the controller.

[0007] As a preferred embodiment, the outer ends of the telescopic brackets are all connected to legs, and the outer ends of the legs are truncated cone structures.

[0008] As a preferred option, the outriggers are fitted with piling boots.

[0009] As a preferred embodiment, the hydraulic device includes a hydraulic cylinder and a push plate, with the fixed end of the hydraulic cylinder mounted on the main rod and the ball bearings disposed on the push plate.

[0010] As a preferred embodiment, the outer side of the lateral telescopic rod is provided with a rolling housing.

[0011] In summary, this utility model has the following advantages:

[0012] 1. The U-shaped sheet pile guide frame of this utility model uses telescopic brackets and a circular level to cooperate with each other to cope with complex construction sites of varying heights and underwater construction sites, and to ensure the horizontal accuracy of the guide frame.

[0013] 2. The U-shaped sheet pile guide frame of this utility model uses multiple sets of ball bearings and a rolling outer shell on the outside of the transverse telescopic rod to reduce friction during the movement of the guide frame and the unloading of the U-shaped sheet pile, which facilitates the movement of the guide frame to the next construction section and provides protection.

[0014] 2. The U-shaped sheet pile guide frame of this utility model effectively mitigates the impact force generated by the collision between the pile body and the guide frame during the pile driving process through a hydraulic device; at the same time, the device can also effectively ensure the verticality of the pile body.

[0015] 4. The U-shaped sheet pile guide frame of this utility model has a transverse telescopic rod between the two main rods. The width of the two main rods can be adjusted by the controller on the main rod to accommodate sheet piles of different sizes. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1-3As shown, this embodiment provides a U-shaped sheet pile guide frame, including two main rods 1 and two transverse telescopic rods 5. The two main rods 1 are spaced apart. The two ends of one transverse telescopic rod 5 are respectively connected to one end of the two main rods 1, and the two ends of the other transverse telescopic rod 5 are respectively connected to the other ends of the two main rods, forming a rectangular frame. The transverse telescopic rods 1 are connected to the main rods 1 with telescopic brackets 10. A circular level 4 is installed on each main rod 1. A hydraulic device 2 is provided on the opposite side of the two main rods 1. The hydraulic device 2 is equipped with ball bearings. A controller 12 is provided on the main rod 1. The telescopic brackets 10 are electrically connected to the controller 12.

[0022] In some embodiments, there may be three lateral telescopic rods 5, namely a first telescopic rod 7, a second telescopic rod 8, and a third telescopic rod 9. The first telescopic rod 7 is connected to one end of each of the two main rods 1, the second telescopic rod 8 is connected to the other end of each of the two main rods 1, and the third telescopic rod 9 is connected to either a telescopic bracket 10 or a rod connected to the telescopic bracket 10. The two ends of this rod are respectively connected to the telescopic bracket 10 and the main rods 1 and the second telescopic rod 8. The third telescopic rod 9 is located below the second telescopic rod 8, and a hydraulic device 2 and ball bearings may also be provided at the connection point between the third telescopic rod 9 and the telescopic bracket 10.

[0023] The outer ends of the telescopic brackets 10 are all connected to legs 11, and the outer ends of the legs 11 are truncated cone structures.

[0024] The support leg 11 is fitted with a piling boot 3.

[0025] The hydraulic device 2 includes a hydraulic cylinder and a push plate. The fixed end of the hydraulic cylinder is mounted on the main rod 1, and the ball bearings are mounted on the push plate.

[0026] A rolling housing 6 is provided on the outside of the horizontal telescopic rod 5.

[0027] Principle: Before construction, the first telescopic rod 7, the second telescopic rod 8, and the third telescopic rod 9 of the guide frame are adjusted by the controller 12 according to the size of the U-shaped sheet pile to adapt to the specifications of the U-shaped sheet pile.

[0028] After ensuring a perfect match between the guide frame and the sheet pile specifications, the pile positions are measured and marked out on the construction site according to the design drawings. Then, the guide frame is moved to the sheet pile construction section using a hoisting machine. The telescopic bracket 10 at the ground end of the guide frame is lowered and inserted into the ground or underwater silt using a controller 12 mounted on the main rod 1. The height of the four telescopic brackets 10 is adjusted by observing the circular level 4 mounted on the main rod 1. If the bubble is centered, the guide frame is level; if the bubble is off-center, it is too high and the height needs to be readjusted to achieve a level position. The guide frame is then secured. At this point, the pile shoe 3 on the telescopic bracket 10 effectively secures the guide frame, preventing it from sinking.

[0029] After the guide frame is leveled and fixed, the sheet pile is first lifted to the designated lifting point by a crane, and then the pile driving can begin. During the lowering process, the ball bearings on the inner side of the main rod 1 of the guide frame have the flexibility to roll in all directions. The ball bearings start to roll in the downward direction of the sheet pile, which effectively reduces the friction between the sheet pile and the guide frame, protects the sheet pile and the guide frame from wear, and optimizes the service life and performance.

[0030] Meanwhile, the hydraulic device 2 inside the main rod 1 of the guide frame and the hydraulic device 2 inside the main rods 1 on both sides abut against the side of the sheet pile, effectively reducing the impact force generated by the collision between the pile body and the guide frame during the pile driving process. It can also observe whether the main plate inside the main rod 1 is offset. If there is an offset, the verticality of the sheet pile can be adjusted to ensure the verticality of the sheet pile.

[0031] After the sheet pile construction of this section is completed, the four brackets of the guide frame are retracted out of the ground using a crane. The pile shoe 3 facilitates the rapid removal of the telescopic feet from the soil. Then, the second telescopic rod 8 and the third telescopic rod 9 are pulled by a machine to move to the next construction section. During the movement, the first telescopic rod 7 is equipped with a rolling shell 6, which, together with the rolling ball, reduces the friction between the pile body and the guide frame, making it easier for the guide frame to move to the next construction section, greatly improving construction efficiency and saving labor.

[0032] Once the guide frame has moved to the designated position in the next section, the above steps can be repeated to continue construction.

[0033] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
