[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Please combine Figure 1, an underground pipe gallery support structure under a railway line in this embodiment includes a fixed pile 4. First, a mounting opening 5 is opened above the fixed pile 4, and a fixed shaft 7 is fixedly installed in the mounting opening 5. In addition, a rotating block 9 is sleeved on the outer side of the fixed shaft 7, and the rotating block 9 is rotatably connected to the fixed shaft 7 through a bearing ring. In addition, a retaining spring 8 is sleeved on the outer side of the fixed shaft 7, and a stopper 10 is fixedly connected to the two side walls of the rotating block 9. That is, the lower end of the retaining spring 8 abuts against the bottom of the mounting opening 5, and the two ends abut against two stoppers 10 respectively.

[0024] An inclined support plate 11 is fixedly connected to one side of the rotating block 9. Under the action of the clamping spring 8, the rotating block 9 and the inclined support plate 11 are pushed to rotate around the fixed shaft 7, so that the inclined support plate 11 is in an inclined state (expanded state). In addition, a limit block 6 is fixedly arranged on the inner top of the installation opening 5. When the inclined support plate 11 is in an inclined state, the limit block 6 contacts the upper surface of the inclined support plate 11 and presses against the inclined support plate 11.

[0025] The oblique support plate 11 is tilted by the action of the clamping spring 8. In order to further fix the oblique support plate 11, a through hole is provided on the rotating block 9, and a first fixing hole 13 and a second fixing hole 14 are provided on the fixing pile 4 and on the side wall at the position of the installation opening 5. In addition, a fixing pin 12 is provided, one end of which is threaded and connected to a fastening nut.

[0026] When the inclined support plate 11 is in an inclined state, the fixing pin 12 is used to simultaneously penetrate the first fixing hole 13 and the through hole on the rotating block 9, and then fixed by a tightening nut. At this time, the rotating block 9 and the fixed shaft 7 cannot continue to rotate relative to each other, so the inclined support plate 11 cannot continue to rotate and is fixed in an inclined state.

[0027] In addition, Figure 3 As shown, when the inclined support plate 11 and the rotating block 9 rotate around the fixed shaft 7, the inclined support plate 11 is stored in a vertical state on the side of the fixed pile 4. At this time, the through hole on the rotating block 9 corresponds to the position of the second fixing hole 14, and the inclined support plate 11 can be fixed by the fixing pin 12, so that the inclined support plate 11 remains in a vertical state. When the inclined support plate 11 is in a vertical state, it is convenient for transportation and storage.

[0028] When the inclined support plate 11 remains in an inclined state, the inclined brace 16 can be installed on the inclined support plate 11. In order to fix the inclined brace 16, a mounting seat plate 15 is provided as a connecting member. First, the mounting seat plate 15 is fixed to the side of the fixed pile 4 by screws. One side of the mounting seat plate 15 is in an "L" shape, which is convenient for installing the inclined brace 16. Bolts are passed through the inclined brace 16, the mounting seat plate 15 and the inclined support plate 11 from top to bottom in sequence. Therefore, the fixed pile 4, the inclined support plate 11 and the inclined brace 16 are fixed by the connecting effect of the mounting seat plate 15.

[0029] In addition, the present embodiment further comprises a frame bridge 1, an underground pipe gallery and a steel pipe 3. The frame bridge 1 is located below the railway line, and the underground pipe gallery is located on one side of the frame bridge 1. The steel pipe 3 is arranged on the side of the fixed pile 4 away from the underground pipe gallery. In addition, an I-beam 2 is fixedly connected to the outer wall of the frame bridge 1.

[0030] The implementation process and principle of an underground pipe gallery support structure under a railway line in the embodiment of the present application are as follows:

[0031] (I): The frame bridge 1 is located below the railway line and is pushed into place by the jacking method. In the railway subgrade soil on one side of the underground pipe gallery to be constructed, a horizontal spiral drilling method is used to drill holes, and then the steel pipes 3 are pressed into the holes, and each steel pipe 3 is arranged vertically.

[0032] (ii) In the middle and both sides of the railway roadbed, a small area of ​​soil is excavated along the steel pipe 3 close to the frame bridge 1, and then the fixed piles 4 are vertically pressed in, so that the middle and both sides of the horizontally arranged steel pipe 3 are supported by the vertically arranged fixed piles 4. The bottom end of the fixed pile 4 should be lower than the bottom surface of the bottom plate of the frame bridge 1, and the inclined support plate 11 needs to face the frame bridge 1 and be exposed from the soil.

[0033] (III): Install the diagonal support 16. First, pull out the fixing pin 12 from the second fixing hole 14. At this time, the diagonal support plate 11 and the rotating block 9 rotate around the fixed shaft 7 under the action of the clamping spring 8 until the diagonal support plate 11 rotates from the vertical position to an inclined state with one end tilted upward. The diagonal support plate 11 will stop rotating when it encounters the limit block 6. Insert the fixing pin 12 into the first fixing hole 13 to prevent the rotating block 9 and the diagonal support plate 11 from rotating further.

[0034] At this time, the mounting base plate 15 is fixedly connected to the fixing pile 4 by screws, and then the diagonal brace 16, the mounting base plate 15 and the diagonal support plate 11 are fixed together by bolts. At the same time, the other end of the diagonal brace 16 can be directly fixed to the I-beam 2 on the side of the frame bridge 1 by screws or welding. The installation is completed.

[0035] (IV): Excavate the soil between the frame bridge 1 and the fixed piles 4. Install the underground pipe gallery. After the construction of the underground pipe gallery is completed, it can be backfilled gradually, and the diagonal braces 16 can be gradually removed during the backfilling process, while the steel pipes 3 and fixed piles 4 are retained.

[0036] Through the above method, the steel pipe 3 and the fixed pile 4 can play a role in supporting the soil, and cooperate with the diagonal brace 16 to provide a safe working environment for the construction of the underground pipe gallery. In addition, the underground pipe gallery and the frame bridge 1 are designed and constructed together, the overall construction period is short, and the impact on the operation of the existing railway line is relatively small.

[0037] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
