This utility model, through the cooperation of the protrusions on the waler and the raised frames on the steel sheet pile, can quickly confine the steel waler to the surface of the steel sheet pile and abut the two ends of the supporting steel pipe against the waler, providing lateral support to the steel sheet pile. The operation is simple and quick, adaptable to pipeline linear engineering construction, providing temporary support, and allowing for rapid and convenient installation and disassembly, reducing construction difficulty and improving construction efficiency.

[0004] However, the above patent still has shortcomings: although the patent can quickly disassemble and assemble the sheet pile support mechanism, it does not have the function of adjusting the height of the support mechanism according to the stress point of the sheet pile, which makes the stress point of the sheet pile relatively weak and affects the support effect. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a detachable sheet pile support mechanism for municipal road pipeline network renovation, which solves the problem mentioned in the background art that although the existing detachable sheet pile support mechanism for municipal road pipeline network renovation can be quickly disassembled and assembled, it cannot adjust the height of the support mechanism according to the stress point of the sheet pile, resulting in the sheet pile being relatively weak at the stress point and affecting the support effect.

[0006] The technical solution of this utility model is:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] A detachable sheet pile support mechanism for municipal road pipeline network renovation includes: two sheet pile bodies 1; two I-beams 2 are provided on each adjacent side of the two sheet pile bodies 1; two adjusting sleeves 3 are provided between the two I-beams 2; two connecting blocks 4 are fixedly connected to the side of the sheet pile body 1 near the I-beams 2; adjusting strips 5 are fixedly connected to the side of the connecting blocks 4 away from the sheet pile body 1; and the adjusting strips 5 have toothed grooves 6 on the side away from the connecting blocks 4. Each section of the clamp strip 5 is equipped with an adjustable disassembly and assembly mechanism 7 for the height of the I-beam 2; the inside of the adjusting sleeve 3 is equipped with a telescopic mechanism 8 that adjusts according to the spacing between the sheet pile bodies 1. The user attaches the two sheet pile bodies 1 to the inner walls of the pit respectively, and then quickly installs the I-beam 2 onto the sheet pile body 1 through the disassembly and assembly mechanism 7, and fixes the I-beam cylinder at the stress point of the sheet pile body 1. Finally, the telescopic mechanism 8 inside the adjusting sleeve 3 pushes the sheet pile body 1 to both sides, so that the sheet pile body 1 fits tightly against the inner wall of the pit.

[0028] like Figure 3 and Figure 4As shown, the disassembly and assembly mechanism 7 includes: a retaining sleeve 9 fixedly connected to each I-beam 2 near the adjusting retaining strip 5; the retaining sleeve 9 is adapted to the adjusting retaining strip 5 and the connecting block 4; a fixing block 10 is fixedly connected inside the retaining sleeve 9; pressing plates 11 are provided on both sides of the fixing block 10; the end of the pressing plate 11 away from the fixing block 10 passes through the retaining sleeve 9 and extends to the outside of the retaining sleeve 9; the pressing plate 11 is slidably connected to the retaining sleeve 9; and two retaining blocks 12 are fixedly connected to each pressing plate 11 near the toothed groove 6; the retaining blocks 12 cooperate with the toothed groove 6. When the user presses the pressing plates 11 on both sides of the retaining sleeve 9, the retaining sleeve 9 is disassembled and assembled. The pressing plate 11 moves into the sleeve 9. As the pressing plate 11 moves, it drives the two locking blocks 12 to move closer to each other. Then, the sleeve 9 is placed on the top of the adjusting strip 5 and the sleeve 9 slides downward on the surface of the adjusting strip 5. When it slides to the stress point of the sheet pile body 1, the pressing plate 11 is released. The two pressing plates 11 slide back to the outside of the sleeve 9 at the same time. As the pressing plate 11 slides back, it drives the locking blocks 12, which in turn locks the locking blocks 12 into the inside of the adjusting strip 5, thereby fixing the I-beam 2 at the stress point of the sheet pile body 1.

[0029] like Figure 4 As shown, sliders 13 are fixedly connected to both sides of the pressing plate 11, and grooves 14 are provided on both sides of the sleeve 9 near the sliders 13. The sliders 13 are slidably connected to the grooves 14 respectively, which allows the pressing plate 11 to slide flexibly inside the sleeve 9 and limits the movement of the pressing plate 11.

[0030] like Figure 6 As shown, the telescopic mechanism 8 includes: two threaded blocks 15 are provided inside the adjusting sleeve 3, and a screw 16 is threadedly connected inside the threaded block 15. A partition 17 is rotatably connected to both ends of the screw 16, and the partition 17 is fixedly connected to the adjusting sleeve 3. Two telescopic plates 18 are fixedly connected to opposite sides of the two threaded blocks 15. The end of each telescopic plate 18 away from the threaded block 15 passes through one of the partitions 17 and extends to the I-beam 2. A limit plate 19 is provided between the two telescopic plates 18 for limiting movement. Plate 19 is fixedly connected to telescopic plate 18, controlling the screw 16 inside the adjusting sleeve 3 to rotate. The screw 16 rotates through the cooperation of partition plate 17. While the screw 16 rotates, it drives the threaded block 15. The two threaded blocks 15 move in opposite directions inside the adjusting sleeve 3. While the threaded blocks 15 move, they drive the telescopic plate 18, causing the telescopic plate 18 to drive the limiting plate 19 to the I-beam 2. Then, through the I-beam 2, the steel sheet pile body 1 is pushed towards the inner wall of the pit, so that the steel sheet pile body 1 is tightly attached to the inner wall of the pit.

[0031] like Figure 6As shown, the adjacent ends of the two screws 16 pass through the partition 17 and extend to the first bevel gear 20. The first bevel gear 20 is fixedly connected to the screws 16. A second bevel gear 21 is provided between the two first bevel gears 20. The first bevel gear 20 meshes with the second bevel gear 21. A rotating shaft 22 is fixedly connected to the center of the second bevel gear 21. The top of the rotating shaft 22 passes through the adjusting sleeve 3 and extends to the knob 23. The rotating shaft 22 is rotatably connected to the adjusting sleeve 3. The knob 23 is fixedly connected to the rotating shaft 22. When the knob 23 is rotated, the rotating shaft 22 is driven, and the rotating shaft 22 drives the second bevel gear 21. The second bevel gear 21 drives the first bevel gears 20 on both sides to rotate in opposite directions. The two first bevel gears 20 drive the screws 16 on both sides to rotate in opposite directions.

[0032] like Figure 5 As shown, two springs 24 are provided between the pressing plate 11 and the fixing block 10. The fixing block 10 is provided with matching spring grooves 25 near the springs 24. When the user releases the pressing plate 11, the springs 24 push the pressing plate 11 to slide to the outside of the sleeve 9 through the cooperation of the fixing block 10.

[0033] like Figure 6 As shown, anti-slip pads 26 are fixedly connected to the outer surface of the knob 23, which makes it convenient for the user to rotate the knob 23 and avoids the user's hand from slipping on the contact surface of the knob 23.

[0034] Working principle: The user attaches the two sheet pile bodies 1 to the inner walls of the pit, then presses the pressing plates 11 on both sides of the sleeve 9, causing the pressing plates 11 to move inward. As the pressing plates 11 move, they simultaneously move the two locking blocks 12 closer together. The sleeve 9 is then placed on top of the adjusting strip 5, and slid downward on the surface of the adjusting strip 5. When it reaches the stress point of the sheet pile body 1, the pressing plates 11 are released. Simultaneously, the spring 24, through the cooperation of the fixing block 10, pushes the pressing plates 11 to slide back outward through the sleeve 9. As the pressing plates 11 slide back, they simultaneously move the locking blocks 12, causing them to engage with the adjusting strip 5, thus fixing the I-beam 2 to the stress point of the sheet pile body 1. Finally, the knob 23 is rotated. The rotation of the knob 23 drives the rotating shaft 22, which in turn drives the second bevel gear 21. The second bevel gear 21 then drives the first bevel gears on both sides. Gear 20 rotates in the opposite direction, and the two first bevel gears 20 drive the screws 16 on both sides to rotate in the opposite direction. The screws 16 rotate through the cooperation of the partition plate 17. While the screws 16 rotate, they drive the threaded blocks 15. The two threaded blocks 15 move in opposite directions inside the adjusting sleeve 3. While the threaded blocks 15 move, they drive the telescopic plate 18, which drives the limiting plate 19 to the I-beam 2. Then, through the I-beam 2, the steel sheet pile body 1 is pushed against the inner wall of the pit, so that the steel sheet pile body 1 is tightly attached to the inner wall of the pit. This allows for the adjustment of the height of the support mechanism according to the stress point of the steel sheet pile, thereby improving the support effect at the stress point of the steel sheet pile. This solves the problem that although the existing detachable steel sheet pile support mechanism used for municipal road pipeline renovation can be quickly disassembled and assembled, it cannot adjust the height of the support mechanism according to the stress point of the steel sheet pile, resulting in the steel sheet pile being relatively weak at the stress point and affecting the support effect.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
