[0002] The roadbed pile-sheet wall refers to a roadbed structure composed of reinforced concrete piles and prefabricated retaining plates (or concrete panels, steel sheet piles) on a weak or unstable foundation. This structure compensates for the lack of foundation strength by the depth of the piles, thereby improving the stability and bearing capacity of the road surface.

[0035] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1-Figure 8 As shown, a roadbed pile sheet wall construction device provided by the present invention is applied to the piling operation of steel sheet piles, provides a position calibration function for the piling operation of steel sheet piles, enables the steel sheet piles to be accurately inserted into the gaps between the steel guide beams, and enables two adjacent steel sheet piles to be effectively buckled, which includes:

[0037] A mobile frame 1 is used for displacement on the steel guide beam. A steel sheet pile entrance 2 is provided at the rear end of the mobile frame 1. Side positioning grooves 3 are provided on both sides of the front end of the mobile frame 1. A front positioning groove 4 is provided between the front ends of the two side positioning grooves 3.

[0038] In this embodiment, the mobile frame 1 is used to walk on the steel guide beam and is adjusted according to the piling position of the steel sheet pile to assist the piling operation of each steel sheet pile. The steel sheet pile lifted by the pile driver directly enters the mobile frame 1 from the steel sheet pile entrance 2, and then is moved to the corresponding lateral positioning groove 3. At this time, the lifted steel sheet pile is docked with the steel sheet pile that has been driven, and the front end of the lifted steel sheet pile is located in the front positioning groove 4. After that, it is only necessary to use the pile driver to move the lifted steel sheet pile downward, and use the guiding effect of the lateral positioning groove 3 and the front positioning groove 4 to make the rear end of the lifted steel sheet pile buckle with the front end of the steel sheet pile that has been driven and then continue to move downward to achieve the piling operation. There are two lateral positioning grooves 3, which are respectively used for the piling operation of two steel sheet piles facing opposite directions.

[0039] The steel sheet pile fixture 5 is used to be sleeved on the top of the outer side of the steel sheet pile that has been piled. The steel sheet pile fixture 5 is slidably arranged on both sides of the mobile frame 1. The steel sheet pile fixture 5 includes a first clamping plate 5-1, a second clamping plate 5-2 rotatably arranged at the rear end of the first clamping plate 5-1, and a third clamping plate 5-3 fixedly arranged at the front end of the first clamping plate 5-1;

[0040] In this embodiment, the steel sheet pile clamp 5 is used to be mounted on the top of the steel sheet pile that has been driven to position the movable frame 1, so that the lateral positioning groove 3 and the front positioning groove 4 can calibrate and guide the steel sheet pile that is being driven, thereby ensuring the stable and effective development of the piling operation.

[0041] During the piling operation, one of the steel sheet pile clamps 5 is located at the rear end of the mobile frame 1 and is mounted on the top of the last steel sheet pile that has been driven. The other steel sheet pile clamp 5 is located at the front end of the mobile frame 1 and is located in the lateral positioning groove 3 on the same side as the mobile frame 1. The steel sheet pile being driven will pass through the steel sheet pile clamp 5 when it moves downward in the lateral positioning groove 3.

[0042] After a steel sheet pile is driven, the second clamping plate 5-2 on the steel sheet pile clamp 5 located at the rear end of the movable frame 1 rotates backward at one end facing inward to avoid the steel sheet pile on which it is mounted, so that the movable frame 1 can switch to a state of moving on the steel guide beam after a steel sheet pile is driven.

[0043] A clamp lock plate 6 is rotatably provided on both sides of the rear end of the mobile frame 1, and is used to block the rear end surface of the second clamp plate 5-2 on the same side thereof, to prevent the second clamp plate 5-2 from rotating backward and disengaging from the steel sheet pile;

[0044] In this embodiment, the clamp lock plate 6 can rotate inward to abut against the rear end surface of the second clamp plate 5-2 in the steel sheet pile clamp 5 located at the rear end of the mobile frame 1 to limit the backward rotation of the second clamp plate 5-2, so that the steel sheet pile clamp 5 located at the rear end of the mobile frame 1 can be stably mounted on the top of the steel sheet pile that has been driven, thereby realizing the positioning of the mobile frame 1 and the alignment and guidance of the steel sheet piles being driven.

[0045] When the steel sheet pile in the piling operation completes the piling operation, after the next steel sheet pile enters the corresponding lateral positioning groove 3, it can drive the clamp lock plate 6 to rotate outward and disengage from the second clamp plate 5-2 restricted by it.

[0046] An outer top block 7 is provided on the outer side wall of each of the two lateral positioning grooves 3, and is used to drive the clamp lock plate 6 on the same side to rotate outward and disengage from the second clamp plate 5-2 when being squeezed outward by the steel guide beam; when the steel sheet pile to be piled enters the corresponding lateral positioning groove 3, the outer top block 7 is squeezed outward to cause the outer top block 7 to move outward, and the outer top block 7 drives the clamp lock plate 6 on the same side to rotate outward and disengage from the second clamp plate 5-2 restricted by it.

[0047] A clamping plate 8 is rotatably provided at the front end of each of the two lateral positioning grooves 3, and the clamping plate 8 is located on the side of the front end positioning groove 4. The front end of the third clamping plate 5-3 is connected to the clamping plate 8, and the clamping plate 8 is arranged so that when the steel guide beam is placed in the lateral positioning groove 3, its outer end rotates forward and drags the corresponding side steel sheet pile clamp 5 forward until it is aligned with the steel guide beam.

[0048] In this embodiment, the fixture drag plate 8 is used to drag the steel sheet pile fixture 5 connected thereto to move forward on the mobile frame 1. Specifically, when the steel sheet pile to be piled enters the corresponding lateral positioning groove 3 and the fixture lock plate 6 is driven to rotate outward by the outer top block 7, after the mobile frame 1 is displaced forward by the forward thrust of the steel sheet pile to be piled, the fixture drag plate 8 rotates forward through the rear end, and the steel sheet pile fixture 5 located at the rear end of the mobile frame 1 is dragged forward as a whole to the position of the front end of the mobile frame 1, and is aligned with the lateral positioning groove 3, so as to facilitate the positioning and guidance of the steel sheet pile to be piled during the downward movement process. At the same time, after the steel sheet pile to be piled completes the piling operation, it is sleeved on the top of the steel sheet pile to limit the next forward movement distance of the mobile frame 1, so as to ensure that the distance of each movement of the mobile frame 1 is the same, so as to be suitable for the piling operation of each steel sheet pile.

[0049] The moving frame 1 has a "C" - shaped structure with an open end facing the rear. Walking wheels 9 for traveling in the outer cavity of the steel guide beam are provided on both sides of the bottom of the moving frame 1. Longitudinal guide rollers 10 are provided on both side walls of the steel sheet pile inlet 2, and the mid - lines of the steel sheet pile inlet 2 and the front - end positioning groove 4 coincide. In this embodiment, the steel sheet pile inlet 2 is in a state with an open rear end. The longitudinal guide rollers 10 limit and guide the steel sheet pile during the process of the steel sheet pile passing through the steel sheet pile inlet 2. At the same time, the resistance is reduced, so that the steel sheet pile can enter the lateral positioning groove 3 more accurately. The walking wheels 9 make it more convenient for the moving frame 1 to move on the steel guide beam.

[0050] A first sliding groove 11 is formed in the inner side wall of the moving frame 1. The first clamping plate 5 - 1 is slidably arranged in the first sliding groove 11. A second sliding groove 12 is formed in the side wall of the moving frame 1. The second clamping plate 5 - 2 is slidably arranged in the second sliding groove 12, and a slope 13 is provided at the front end of the inner side wall of the second sliding groove 12. The top of the slope 13 is flush with the inner side wall of the moving frame 1. When the second clamping plate 5 - 2 moves forward to the top of the slope, it is in a state of closely adhering to the rear - end inclined surface of the outer wall of the steel sheet pile.

[0051] In this embodiment, when the steel sheet pile clamp 5 moves forward from the rear end of the moving frame 1 to the lateral positioning groove 3 on the same side, the first clamping plate 5 - 1 moves forward in the first sliding groove 11 to the front end of the first sliding groove 11, and the second clamping plate 5 - 2 moves forward in the second sliding groove 12. Among them, before the second clamping plate 5 - 2 passes through the slope 13, it is in a state with the inner end facing backward. In this state, the inner side surface of the second clamping plate 5 - 2 is flush with the outer side surface of the steel sheet pile. During the process of the second clamping plate 5 - 2 passing through the slope 13 and moving to the top of the slope 13, the second clamping plate 5 - 2 is blocked by the slope 13, so that the second clamping plate 5 - 2 switches to a state with the rear - side end facing inward after passing over the previous steel sheet pile. At this time, an isosceles trapezoid structure adapted to the outer surface of the steel sheet pile is formed among the first clamping plate 5 - 1, the second clamping plate 5 - 2 and the third clamping plate 5 - 3, and it is in a state capable of sleeving the steel sheet pile. And after the second clamping plate 5 - 2 moves to the top of the slope, its outer side surface contacts the surface of the top of the slope. At this time, the second clamping plate 5 - 2 can be locked in this state.

[0052] The clamp locking plate 6 has an inverted "L" - shaped structure. A connecting rod 14 is fixedly connected to the top end of the front side surface of the clamp locking plate 6. The front end of the connecting rod 14 is fixedly connected to a rotating sleeve 15. The top end of the rotating sleeve 15 is rotatably connected to the outer wall surface of the moving frame 1. Longitudinal slots 16 are formed on both the front and rear sides of the rotating sleeve 15. A transverse sliding rod 17 is slidably connected between the two longitudinal slots 16. The side surface of the transverse sliding rod 17 facing the moving frame 1 is connected with an elastic telescopic rod 18, and the elastic telescopic rod 18 is fixedly installed on the moving frame 1. The outer top block 7 is within the range of the rotating sleeve 15 in the height direction, and the top block rotates the rotating sleeve 15 outward so that the clamp locking plate 6 rotates outward and disengages from the second clamping plate 5 - 2.

[0053] In this embodiment, by utilizing the elastic force of the elastic telescopic rod 18, in the initial state, the elastic telescopic rod 18 can keep the fixture lock plate 6 rotating to a state where the second fixture plate 5-2 can be restricted. When the outer top block 7 pushes the rotating sleeve 15 to rotate outward, the connecting rod 14 drives the fixture lock plate 6 to rotate outward and detach from the rear area of ​​the second fixture plate 5-2 on the same side as the outer top block 7.

[0054] A transverse groove 19 is provided on the clamping plate 8, and a longitudinal slide bar 20 is fixedly connected to the front end of the third clamping plate 5-3, and the longitudinal slide bar 20 is slidably arranged in the transverse groove 19. In this embodiment, when the clamping plate 8 rotates, the longitudinal slide bar 20 slides in the transverse groove 19.

[0055] Among them, the top of the inner end of the clamping carriage 8 is fixedly connected with a mounting shaft 21, and the mounting shaft 21 is rotatably mounted on the mobile frame 1. The outer side of the mounting shaft 21 is fixedly provided with a first push block 22 and a second push block 23. The first push block 22 and the second push block 23 are symmetrically distributed, and the first push block 22 is parallel to the clamping carriage 8.

[0056] The mounting shaft 21 serves as a rotation fulcrum of the fixture carriage 8, and the fixture carriage 8 is stably rotatably mounted on the mobile frame 1. The first push block 22 and the second push block 23 are both used to be hit by the steel sheet piles to be driven into the lateral positioning groove 3, and then, the force of the steel sheet piles to be driven is used to push the mobile frame 1 and drive the fixture carriage 8 to rotate automatically, so as to achieve the adaptive adjustment of the positions of the mobile frame 1 and the steel sheet pile fixture 5.

[0057] The side surface of the first push block 22 facing the center of the moving frame 1 is an arc-shaped surface. When the steel sheet pile clamp 5 is located at the rear end of the moving frame 1, the distance between the rear end of the first push block 22 and the rear inner wall surface of the lateral positioning groove 3 is greater than the width of the outer wall of the steel sheet pile. In this way, the first push block 22 can more effectively provide driving force for the rotation of the clamp carriage 8 when it is pushed by the steel sheet pile.

[0058] The front side of the mobile frame 1 located at the lateral positioning groove 3 is provided with an accommodating cavity, which connects the lateral positioning groove 3 with the front positioning groove 4, wherein:

[0059] When the steel sheet pile fixture 5 is located at the rear end of the mobile frame 1, the fixture drag plate 8 is in a state where the rear end is tilted outward, the end of the first push block 22 away from the installation shaft 21 is located in the inner cavity of the lateral positioning groove 3, and the end of the second push block 23 away from the installation shaft 21 is located in the accommodating cavity;

[0060] When the steel sheet pile clamp 5 is located at the front end of the mobile frame 1, the clamp drag plate 8 is perpendicular to the mobile frame 1, the end of the first push block 22 away from the installation shaft 21 is located in the accommodating cavity, and the end of the second push block 23 away from the installation shaft 21 is located in the front end positioning groove 4.

[0061] In this embodiment, when the steel sheet pile to be driven is completely inserted into the front end positioning groove 4 , its front end is inserted into the front end positioning groove 4 .

[0062] A baffle 24 is provided at the bottom of the steel sheet pile entrance 2, and the height of the baffle 24 is greater than the height of the fixture drag plate 8, and the height of the baffle 24 is less than the height of the outer top block 7. The baffle 24 is used to limit the height of the steel sheet pile lifted by the pile driver, so that the height of the steel sheet pile is always greater than the height of the fixture drag plate 8 during the process of moving the steel sheet pile into the lateral positioning groove 3, so as to prevent the fixture drag plate 8 from blocking the steel sheet pile from effectively entering the lateral positioning groove 3.

[0063] The following further describes the use of the roadbed pile-sheet wall construction device of this embodiment:

[0064] ① First, use the pile driver to complete the piling operation of the first steel sheet pile. After completion, slide the mobile frame 1 onto the steel guide beam through the walking wheels 9. At this time, the mobile frame 1 is stably slidably sleeved on the steel guide beam. Then, move the steel sheet pile fixture 5 on the same side as the first steel sheet pile to the rear end of the mobile frame 1 and sleeve it onto the first steel sheet pile.

[0065] Move the steel sheet pile fixture 5 on the opposite side of the first steel sheet pile to the front end of the mobile frame 1, and rotate the fixture drag plate 8 on the opposite side of the first steel sheet pile to a state perpendicular to the mobile frame 1. At this time, the mobile frame 1 is positioned by the steel sheet pile fixture 5 on the first steel sheet pile, and the steel sheet pile fixture 5 on the opposite side of the first steel sheet pile is aligned with the lateral positioning groove 3, the second push block 23 on the opposite side of the first steel sheet pile is located in the front end positioning groove 4, the first push block 22 on the opposite side of the first steel sheet pile is located in the accommodating cavity, and the second clamping plate 5-2 on the first steel sheet pile is located on the top of the slope 13 and is fixed.

[0066] ② Use a pile driver to lift the second steel sheet pile and make it pass through the steel sheet pile entrance 2. After the outer side of the second steel sheet pile enters the lateral positioning groove 3, use the pile driver to move the second steel sheet pile to the opposite side of the first steel sheet pile. At this time, the second steel sheet pile will push the outer top block 7 located on the opposite side of the first steel sheet pile outward, causing the fixture lock plate 6 located on the opposite side of the first steel sheet pile to rotate outward. After the outer side of the second steel sheet pile contacts the side wall of the lateral positioning groove 3 located on the opposite side of the first steel sheet pile, use the pile driver to drive the second steel sheet pile to move forward, so that the front end of the second steel sheet pile is inserted into the front end positioning groove 4.

[0067] At this time, the second steel sheet pile fits into the lateral positioning groove 3, and the steel sheet pile fixture 5 located on the opposite side of the first steel sheet pile is located directly below the second steel sheet pile and is in an aligned state.

[0068] Then, the second steel sheet pile starts to move downward. Under the guidance of the lateral positioning groove 3 and the front positioning groove 4, the second steel sheet pile passes through the steel sheet pile clamp 5 below it and is clamped with the first steel sheet pile. After that, the steel sheet pile driving operation is carried out.

[0069] After the piling operation of the second steel sheet pile is completed, the two steel sheet pile fixtures 5 are respectively sleeved on the top of the first steel sheet pile and the second steel sheet pile.

[0070] ③ Use a pile driver to lift the third steel sheet pile and move the third steel sheet pile from the steel sheet pile entrance 2 into the range of the lateral positioning groove 3. The pile driver makes the outer side of the third steel sheet pile stick to the side wall of the lateral positioning groove 3 on the opposite side of the second steel sheet pile. At this time, the third steel sheet pile pushes the outer top block 7 on the opposite side of the second steel sheet pile outward, so that the clamp lock plate 6 at the rear end of the first steel sheet pile rotates outward and disengages from the second clamp plate 5-2 at the rear end of the first steel sheet pile.

[0071] ④ Use the pile driver to move the third steel sheet pile forward, and the third steel sheet pile provides forward thrust for the mobile frame 1. At this time, the mobile frame 1 moves forward on the steel guide beam, and the steel sheet pile fixture 5 located on the side of the first steel sheet pile moves forward synchronously with the mobile frame 1 and crosses the first steel sheet pile, while the steel sheet pile fixture 5 located on the second steel sheet pile remains clamped on the second steel sheet pile. When the second clamping plate 5-2 sleeved on the rear side of the second steel sheet pile contacts the fixture lock plate 6, the mobile frame 1 moves forward to the farthest position. At this time, under the thrust of the third steel sheet pile, the first push block 22 located on the opposite side of the second steel sheet pile is pushed by the third steel sheet pile, causing the fixture drag plate 8 to swing, and the fixture drag plate 8 pulls the steel sheet pile fixture 5 located on the opposite side of the second steel sheet pile forward, causing it to move to the lateral positioning groove 3 located on the opposite side of the second steel sheet pile and be located directly below the third steel sheet pile.

[0072] ⑤ Use the pile driver to move the third steel sheet pile downward, and the third steel sheet pile passes downward through the steel sheet pile fixture 5 located on the opposite side of the second steel sheet pile, and then the third steel sheet pile is driven. And so on, the steel sheet piles are driven one by one in sequence.

[0073] In summary, after applying the roadbed pile-sheet wall construction device provided in this embodiment, the insertion of the steel sheet piles into the steel guide beam and the interlocking calibration of the two steel sheet piles do not require manual intervention, and can be directly performed by the pile driver by adjusting the position of the steel sheet piles in the mobile frame 1, so that the piling operation of each steel sheet pile can be carried out more conveniently and efficiently, which not only has high piling efficiency, but also utilizes the guiding effect to ensure the verticality of the steel sheet piles.

[0074] The technical scope of the present invention is not limited to the contents of the above description.
