[0002] With the continuous development of rail transit technology, subway construction has also developed rapidly. Among them, the subway line needs to climb to the ground level when entering the site, and it is often necessary to set up a U-shaped trough section to transition to the underground section. The conventional U-shaped trough section adopts slope excavation, and the outer side of the main body is backfilled after the construction is completed.
[0003] The existing Chinese public patent (authorization announcement number: CN211113780U) mentions a U-shaped trough section waterproof structure for subway construction, including a U-shaped trough section body, the U-shaped trough section body includes a structural bottom plate and a structural side wall, a longitudinal construction joint is provided at the connection between the structural bottom plate and the structural side wall, a galvanized steel plate water stop is provided on the longitudinal construction joint, a concrete protective layer is provided at the lower end of the structural bottom plate, a first waterproof layer is provided on the outer side of the concrete protective layer, and a concrete cushion layer is provided at the lower end of the first waterproof layer. The utility model improves the waterproof performance of the side of the U-shaped trough section body through the galvanized steel plate water stop, and at the same time improves the waterproof performance of the bottom of the U-shaped trough section body through the concrete protective layer and the first waterproof layer, so as to improve the waterproof effect while ensuring the normal support function of the U-shaped trough section body, and solves the problem that the existing U-shaped trough sections cannot effectively ensure the waterproof performance because most of them directly rely on the concrete itself to provide waterproofing.
[0004] In the above patent, the waterproof performance of the bottom of the main body of the U-shaped trough section is improved by combining a concrete protective layer with a first waterproof layer. However, in actual use, this patent requires pouring a structural bottom plate inside the foundation and then pouring a structural side wall to form a U-shaped trough. Most of these are poured on site, which not only requires mobile construction according to the trough body but also leads to a long construction period and cannot effectively control the quality between each U-shaped trough. For this reason, the present application provides a stable and waterproof structure for a U-shaped trough for track construction. Utility Model Content

[0033] The following is combined with Figure 1-5 This application is described in further detail.
[0034] The embodiments of the present application disclose a U-shaped groove stable waterproof structure for track construction.
[0035] Reference Figure 1 and Figure 2 The U-shaped groove stable waterproof structure for track construction includes a foundation 1, a U-shaped foundation pit is opened inside the foundation 1, waterproof partitions 5 are fixedly connected on both sides of the U-shaped foundation pit, a U-shaped groove body 6 is installed in the U-shaped foundation pit, connecting parts are installed on both sides of the U-shaped groove body 6, through holes are symmetrically opened on the top of the U-shaped groove body 6, and a stable component 7 is installed inside the through hole, a concrete cushion layer 2 is fixedly connected to the bottom of the U-shaped foundation pit, a waterproof layer 3 is fixedly connected to the top of the concrete cushion layer 2, and a concrete protective layer 4 is fixedly connected to the top of the waterproof layer 3.
[0036] When in use, firstly, a layer of concrete cushion layer 2 is poured in the U-shaped foundation pit of the foundation 1, and then a waterproof layer 3 and a concrete protective layer 4 are poured on the top of the concrete cushion layer 2 in sequence, and finally the waterproof partition 5 is fixed on both sides of the U-shaped foundation pit, and then the U-shaped trough body 6 is erected and installed in the U-shaped foundation pit inside the foundation 1 by means of external cranes and other equipment, so that both sides of the U-shaped trough body 6 are in contact with the waterproof partition 5, and the bottom of the U-shaped trough body 6 is in contact with the top of the concrete protective layer 4. The waterproof effect of the entire U-shaped trough body 6 can be greatly improved through the mutual cooperation of the waterproof layer 3, the concrete protective layer 4 and the waterproof partition 5. When the U-shaped trough body 6 is placed on the U After the U-shaped foundation pit is inside, the stabilizing component 7 in the through hole can be rotated. Through the operation of the stabilizing component 7, the U-shaped trough body 6 can be quickly and stably fixed on the foundation 1. When one of the U-shaped trough bodies 6 is stabilized, the next U-shaped trough body 6 can be placed in the U-shaped foundation pit again, and then the two U-shaped trough bodies 6 are spliced and fixed through connecting parts. Through the rapid splicing and installation between multiple U-shaped trough bodies 6, there is no need to directly cast on site, which greatly saves construction time, effectively controls the quality of the U-shaped trough body 6, and facilitates construction and laying, which can be quickly supported and waterproofed, greatly saving construction time.
[0037] Reference Figure 1 and Figure 3 The connecting piece includes a U-shaped slot 61 opened on one side of the U-shaped slot body 6, and a U-shaped block 62 is fixedly connected to the side of the U-shaped slot body 6 away from the U-shaped slot 61. The shape and size of the U-shaped block 62 are consistent with the U-shaped slot 61, and the length of the U-shaped block 62 is twice that of the U-shaped slot 61. Baffles 63 are fixedly connected at both ends of the U-shaped block 62, and a plurality of injection holes 64 are evenly opened on the U-shaped block 62.
[0038] When in use, first fix one U-shaped groove body 6 in the U-shaped foundation pit, then take out the other U-shaped groove body 6 and put it into the U-shaped foundation pit, and then insert the U-shaped block 62 on one side of one U-shaped groove body 6 into the U-shaped groove 61 on one side of the other U-shaped groove body 6. Because the length of the U-shaped block 62 is twice that of the U-shaped groove 61, after the U-shaped block 62 is fully inserted into the U-shaped groove 61, a part of the injection molding chamber will be formed between the two U-shaped groove bodies 6. At this time, concrete can be poured into the injection molding chamber through the injection molding hole 64. The two U-shaped groove bodies 6 are completely fixed and connected together by pouring concrete, thereby greatly improving the stability between each U-shaped groove body 6.
[0039] Reference Figure 1 , Figure 4 and Figure 5 The stabilizing component 7 includes a stabilizing nail 71 fixedly connected to the bottom end of the through hole, a threaded rod 72 is rotatably connected inside the stabilizing nail 71, a handle 73 is fixedly connected to the top of the threaded rod 72, an extrusion block 74 is threadedly connected to the threaded rod 72, a guide rod 75 is symmetrically fixedly connected inside the stabilizing nail 71, and both sides of the extrusion block 74 are slidably connected to the guide rod 75, two support plates 76 are symmetrically fixedly connected inside the stabilizing nail 71, and the bottoms of the two support plates 76 are rotatably connected to triangular blocks 77, and adjustment grooves 78 are opened on both sides of the stabilizing nail 71, and the triangular blocks 77 are located inside the stabilizing nail 71 and parallel to the adjustment grooves 78;
[0040] Secondly, a T-shaped slot 79 is provided inside the triangular block 77, and a slide rod 710 is slidably connected to the inside of the T-shaped slot 79, and a limit block 711 is fixedly connected to the bottom of the slide rod 710. A spring 712 is fixedly connected to the top of the limit block 711, and the slide rod 710 is located inside the spring 712. Two push rods 713 are symmetrically slidably connected inside the T-shaped slot 79, and sliders 714 are fixedly connected on both sides of the limit block 711. The corresponding surfaces of the two push rods 713 are provided with oblique grooves, and the sliders 714 are slidably connected in the oblique grooves.
[0041] When in use, after the U-shaped groove body 6 is placed in the U-shaped foundation pit, according to the influence of gravity of the U-shaped groove body 6, the stabilizing nail 71 will directly penetrate into the interior of the foundation 1. At this time, the handle 73 can be twisted into the through hole to rotate, thereby driving the threaded rod 72 to rotate. When the threaded rod 72 rotates, the extrusion block 74 will gradually descend on the threaded rod 72 according to the guidance of the guide rod 75, and the bottom of the extrusion block 74 will fit with the top corner of the triangular block 77. As the extrusion block 74 descends, the triangular block 77 will be driven to rotate and extend into the stabilizing nail 71 through the adjustment slot 78. The extended triangular block 77 can make the stabilizing nail 71 stably fixed in the foundation 1, effectively improving the stability of the U-shaped groove body 6 on the foundation 1, and at the same time, the U-shaped groove body 6 will not sink during long-term use.
[0042] Secondly, when the triangular block 77 gradually rotates and extends out of the stabilizing nail 71, the top surface of the triangular block 77 will fit tightly with one side of the extrusion block 74. At this time, one side of the extrusion block 74 will squeeze the slide bar 710 to move inside the T-shaped groove 79. When the slide bar 710 moves, it will drive the limit block 711 to move in the T-shaped groove 79. Because the slider 714 on one side of the limit block 711 is slidably connected with the oblique groove on one side of the push rod 713, when the limit block 711 moves, it will push the two push rods 713 to extend out from the inside of the T-shaped groove 79. Through the extension of the two push rods 713, the stability of the U-shaped groove body 6 on the foundation 1 can be further improved, so that the U-shaped groove body 6 can be stabilized in the U-shaped foundation pit.
[0043] The implementation principle of the U-shaped trough stable waterproof structure of the track construction in this embodiment is as follows: when in use, a layer of concrete cushion layer 2 is first poured in the U-shaped foundation pit of the foundation 1, and then a waterproof layer 3 and a concrete protective layer 4 are poured on the top of the concrete cushion layer 2 in sequence, and finally the waterproof partition 5 is fixed on both sides of the U-shaped foundation pit, and then the U-shaped trough body 6 is erected and installed in the U-shaped foundation pit inside the foundation 1 through external cranes and other equipment, so that the two sides of the U-shaped trough body 6 are in contact with the waterproof partition 5, and the bottom of the U-shaped trough body 6 is in contact with the top of the concrete protective layer 4. The waterproof effect of the entire U-shaped trough body 6 can be greatly improved through the mutual cooperation of the waterproof layer 3, the concrete protective layer 4 and the waterproof partition 5. When the U-shaped trough body 6 is placed inside the U-shaped foundation pit, according to the U-shaped The gravity of the groove body 6 will cause the stabilizing nail 71 to penetrate directly into the interior of the foundation 1. At this time, the handle 73 can be twisted into the through hole to rotate, thereby driving the threaded rod 72 to rotate. When the threaded rod 72 rotates, the extrusion block 74 will gradually descend on the threaded rod 72 according to the guidance of the guide rod 75, and the bottom of the extrusion block 74 will fit with the top corner of the triangular block 77. As the extrusion block 74 descends, the triangular block 77 will rotate and extend into the stabilizing nail 71 through the adjustment slot 78. The extended triangular block 77 can make the stabilizing nail 71 stably fixed in the foundation 1, effectively improving the stability of the U-shaped groove body 6 on the foundation 1, and at the same time, the U-shaped groove body 6 will not sink during long-term use.
[0044] Secondly, when the triangular block 77 gradually rotates and extends the stabilizing nail 71, the top surface of the triangular block 77 will fit closely with one side of the extrusion block 74. At this time, one side of the extrusion block 74 will squeeze the slide bar 710 to move inside the T-shaped groove 79. When the slide bar 710 moves, it will drive the limit block 711 to move in the T-shaped groove 79. Because the slider 714 on one side of the limit block 711 is slidably connected with the oblique groove on one side of the push rod 713, when the limit block 711 moves, it will push the two push rods 713 to extend from the inside of the T-shaped groove 79. The extension of the two push rods 713 can further improve the stability of the U-shaped groove body 6 on the foundation 1, so that the U-shaped groove body 6 can be stabilized in the U-shaped foundation pit;
[0045] In addition, when one of the U-shaped groove bodies 6 is stable, the other U-shaped groove body 6 can be taken out and placed in the U-shaped foundation pit, and then the U-shaped block 62 on one side of one of the U-shaped groove bodies 6 can be inserted into the U-shaped groove 61 on the other side of the U-shaped groove body 6. Because the length of the U-shaped block 62 is twice that of the U-shaped groove 61, after the U-shaped block 62 is fully inserted into the U-shaped groove 61, a part of the injection molding chamber will be formed between the two U-shaped groove bodies 6. At this time, concrete can be poured into the injection molding chamber through the injection molding hole 64. The two U-shaped groove bodies 6 are completely fixed and connected together through the pouring of concrete, thereby greatly improving the stability between each U-shaped groove body 6. Through the rapid splicing and installation between multiple U-shaped groove bodies 6, there is no need to directly cast on site, which greatly saves construction time, effectively controls the quality of the U-shaped groove body 6, and is convenient for construction and laying, which can be quickly supported and waterproofed, greatly saving construction time.
