[0003] A search revealed a construction support structure for deep-buried sewage pipes in soft soil, as disclosed in announcement number CN214116647U. Its main features include: sheet pile assemblies; multiple sets of sheet pile assemblies are driven into the soft soil foundation by a tracked excavator equipped with a vibratory hammer; the sheet pile assemblies are arranged in two rows; inner support plate assemblies are hung on the inner sides of both rows of sheet pile assemblies; multiple sets of inner support pipe assemblies are tightly fitted between the two sets of inner support plate assemblies; the sheet pile assemblies include U-shaped sheet piles, with locking bends fixedly installed on both sides of the U-shaped sheet piles; the inner support plate assemblies include I-shaped inner support plates, with multiple pull rings fixedly installed on the top of each I-shaped inner support plate, and hooks attached to each pull ring via steel wire ropes; the inner support pipe assemblies include circular inner support pipes, with mounting cross plates fixedly installed on the circular inner support pipes.

[0004] In actual use, the applicant found that the above-mentioned sewage pipe construction support structure is suspended from the steel sheet piles by a cable. However, due to the height error and position deviation of the steel sheet piles during installation, the horizontal level of the I-beams cannot be guaranteed. At the same time, the I-beams on both sides of the foundation pit cannot be at the same height and parallelism, which makes it impossible to attach suitable I-beams to both ends of the inner support pipe. In order to solve the above-mentioned problems, a sewage pipe construction support structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a sewage pipe construction support structure in order to solve the problems mentioned above.

[0007] The suspension assembly includes a frame-shaped rotating frame, one end of which is threadedly connected to an adjusting screw. One end of the adjusting screw is fixedly connected to an upper hook, which is hooked to the upper end of the sheet pile. The other end of the frame-shaped rotating frame is movably connected to a suspension cable. One end of the suspension cable is fixedly connected to a stop block, and the other end of the suspension cable is fixedly connected to a lower hook, which is hooked to the hook seat.

[0008] The I-beam has several threaded holes on its flange near the sheet pile, and an adjusting bolt is connected to the internal thread of each threaded hole.

[0009] In a preferred embodiment, the sheet pile includes a U-shaped plate, and the two sides of the U-shaped plate are integrally bent to form U-shaped locking bends.

[0010] In a preferred embodiment, the inner support plate of the I-beam is provided with a plurality of threaded holes, and the hook seat is threadedly connected to the threaded holes.

[0011] In a preferred embodiment, the I-beam has several through holes on its flange away from the sheet pile, and the positions of the through holes correspond to the positions of the threaded holes.

[0012] In a preferred embodiment, the inner push rod includes a main rod, both sides of which are provided with internal threaded holes. A lead screw is internally threaded into the internal threaded holes, and an L-shaped clamping plate is fixedly installed at one end of the lead screw.

[0013] In a preferred embodiment, the main rod has an insertion hole in the middle.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this utility model, an adjustable-length suspension assembly is used to adjust the level and working height of the I-beams according to the height error between the sheet piles. At the same time, the adjusting bolt in the threaded hole can be rotated to adjust the I-beams on both sides of the foundation pit to be set in parallel according to the positional offset error between the sheet piles. The above structure can effectively avoid the installation error of the sheet piles causing the two I-beams to be unable to meet the installation of the inner top rod, ensuring the stable installation of the inner top rod and improving the strength of the subsequent support.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] The following will combine Figures 1-3 A detailed description of a sewage pipe construction support structure according to an embodiment of this utility model is provided.

[0022] Example:

[0023] This utility model provides a sewage pipe construction support structure, which is referenced in the following embodiment. Figures 1 to 3 As shown, the structure includes a foundation pit 1 for sewage pipe construction. Several sheet piles 2 are inserted into the two inner walls of the foundation pit 1. A suspension assembly 3 is attached to the upper end of the sheet pile 2, and a hook seat 4 is hooked to the lower part of the suspension assembly 3. I-beams 5 are threaded onto the hook seat 4. An inner top rod 6 is tightly connected between the I-beams 5 on the two inner walls of the foundation pit 1. In this structure, the suspension assembly 3 is used to hang the I-beams 5 on the sheet piles 2, and then the inner top rod 6 is used to push against the two I-beams 5 outward, thereby supporting the sheet piles 2 on both sides of the foundation pit 1, thus ensuring the safe laying of the sewage pipe in the foundation pit 1.

[0024] refer to Figures 1 to 3As shown, the suspension assembly 3 includes a frame-shaped rotating frame 7. One end of the frame-shaped rotating frame 7 is threadedly connected to an adjusting screw 8. One end of the adjusting screw 8 is fixedly connected to an upper hook 9, which is hooked to the upper end of the sheet pile 2. The other end of the frame-shaped rotating frame 7 is movably connected to a suspension cable 10. One end of the suspension cable 10 is fixedly connected to a stop block 11, and the other end of the suspension cable 10 is fixedly connected to a lower hook 12, which is hooked to a hook seat 4. The above structure constitutes the suspension assembly 3. The upper hook 9 is hooked to the sheet pile 2, and the lower hook 9 is hooked to the hook seat 4 on the I-beam 5. The I-beam 5 is then suspended by the suspension cable 10, the frame-shaped rotating frame 7, and the adjusting screw 8, thereby fixing the I-beam 5 to the steel plate 2.

[0025] During use, personnel can rotate the frame-shaped rotating frame 7 using tools. This allows adjustment of the position of the frame-shaped rotating frame 7 on the adjusting screw 8, thereby adjusting the length of the entire suspension structure. This enables the adjustment of the level and working height of the I-beam 5 according to the height error of the sheet pile 2, facilitating the installation of the inner top rod 6.

[0026] refer to Figures 1 to 3 As shown, several threaded holes 13 are provided on the flange of the I-beam 5 near the sheet pile 2. An adjusting bolt 14 is threaded into the threaded hole 13. In this structure, by rotating the adjusting bolt 14 in the threaded hole 13, the I-beam 5 on both sides of the foundation pit 1 can be adjusted to be set in parallel according to the positional offset error between the sheet piles 2, so as to facilitate the installation of the inner fixing rod 6.

[0027] refer to Figures 1 to 3 As shown, the sheet pile 2 includes a U-shaped plate 15. The two sides of the U-shaped plate 15 are integrally bent with U-shaped locking plates 16. This structure of U-shaped plate 15 and U-shaped locking plates 16 forms the sheet pile 2. The U-shaped locking plates 16 can lock two adjacent U-shaped plates 15 together to form a steel sheet retaining wall to prevent soil from entering the foundation pit 1.

[0028] refer to Figures 1 to 3 As shown, the inner support plate of the I-beam 5 has several threaded holes 17, and the hook seat 4 is threadedly connected to the threaded holes 17. In this structure, the threaded holes 17 facilitate the connection of the hook seat 4.

[0029] refer to Figures 1 to 3 As shown, several through holes 18 are provided on the flange of the I-beam 5 away from the sheet pile 2. The position of the through holes 18 corresponds to the position of the threaded hole 13. This structure uses the through holes 18 to facilitate the connection of the longer adjusting bolt 14 with the threaded hole 13, avoiding the situation where the spacing of the I-beam 5 is too short, which would prevent the adjusting bolt 14 from being installed.

[0030] refer to Figures 1 to 3As shown, the inner top rod 6 includes a main rod 19. Both sides of the main rod 19 have internal threaded holes 20. The internal threaded holes 20 are internally threaded with screw rods 21. One end of the screw rod 21 is fixedly installed with an L-shaped clamping plate 23. In this structure, the personnel can first adjust the screw rod 21 to extend out of the internal threaded holes 20 so that the length between the main rod 19 and the screw rod 21 meets the spacing between the I-beams 5. Then, the L-shaped clamping plate 23 is clamped on the I-beams 5. Then, the personnel rotate the main rod 19 to drive the screw rod 21 to move, so that the L-shaped clamping plate 23 is pressed between the two I-beams 5, thereby completing the clamping support.

[0031] refer to Figures 1 to 3 As shown, the main rod 19 has a socket 22 in the middle. This structure makes it easy to insert tools through the socket 22, thus facilitating the rotation of the main rod 19.

[0032] It should be noted that the construction support structure disclosed in the above embodiments is used in the construction of deeply buried sewage pipes.

[0033] The implementation principle of a sewage pipe construction support structure according to an embodiment of this application is as follows: In use, the I-beam 5 is hung on the sheet pile 2 using the suspension assembly 3. After it is suspended, the personnel can rotate the frame-type rotating frame 7 with tools. At this time, the position of the frame-type rotating frame 7 on the adjusting screw 8 can be adjusted, and the length of the entire suspension structure can be adjusted. Thus, the level and working height of the I-beam 5 can be adjusted according to the height error of the sheet pile 2. Then, according to the offset error between the sheet piles 2, the personnel can adjust the I-beams 5 on both sides of the pit 1 to be parallel by rotating the adjusting bolt 14 in the threaded hole 13. Then, the personnel can first adjust the screw rod 21 to extend from the internal threaded hole 20 so that the length between the main rod 19 and the screw rod 21 meets the spacing between the I-beams 5. Then, the L-shaped clamping plate 23 is clamped on the I-beam 5. Then, the personnel rotate the main rod 19 to drive the screw rod 21 to move, so that the L-shaped clamping plate 23 is pressed between the two I-beams 5, thereby completing the tight support.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this 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 of the technical features.
