[0001] This invention belongs to the field of roadbed support and protection technology, specifically relating to an emergency reinforcement structure and method for railway embankment defects. Background Technology

[0002] In response to the damage to the retaining structure caused by embankment landslides and collapses, the main measure currently adopted in the project is to install pile-slab wall structures for support. For roadbeds in landslide areas where retaining structures have already been installed, the original retaining structures need to be demolished after temporary protection is in place, and then new retaining structures need to be reinstalled. This method results in a long construction period and cannot meet the timeliness requirements for embankment reinforcement in railway landslide areas. Furthermore, there is a risk of secondary collapse of the landslide body after the original retaining structure is removed. Therefore, the existing retaining structure repair cannot meet the timeliness and safety requirements. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides an emergency reinforcement structure for railway embankment defects, used to form a reinforcement structure at the retaining structure on one side of the embankment slope, comprising: A support panel is attached to one side of the inclined surface of the support structure, and a support structure is provided at intervals from the support panel. The support structure is located on the side of the support panel away from the support structure, and the vertical portion of the support structure extends into the ground plane. A support plate is provided between the support panel and the support structure. One end of the support plate abuts against the inclined surface of the support panel, and the other end abuts against the support structure, so as to press the support panel against the inclined surface of the support structure.

[0005] As a further improvement of the present invention, the support structure includes anti-slide piles arranged vertically, one end of the anti-slide piles extending into the ground plane and the other end extending vertically out of the ground plane; One end of the support plate is connected to the anti-slide pile, and the other end abuts against the support panel.

[0006] As a further improvement of the present invention, there are multiple anti-slide piles, which are arranged along the extension direction of the track, and the multiple anti-slide piles are connected by a cap beam; There are multiple support plates, one end of each support plate abuts against the support panel, and the other end of each support plate abuts against the anti-slide pile.

[0007] As a further improvement of the present invention, the anti-slide pile includes a square column and a bored pile respectively arranged vertically, wherein the square column and the bored pile are integrally formed; The square column has a square cross-section along the horizontal direction, and the bored pile has a circular cross-section along the horizontal direction. The cross-sectional area of ​​the square column along the horizontal direction is larger than that of the bored pile along the horizontal direction. The bored pile is located below the ground plane, and the square column is located above the ground plane.

[0008] As a further improvement of the present invention, at least one drainage hole is provided on the retaining structure and the supporting panel. The drainage hole is arranged along the inclined direction of the embankment slope, and one end of the drainage hole extends into the inner side of the embankment slope, while the other end passes through the retaining structure and the supporting panel.

[0009] As a further improvement of the present invention, the depth of the drainage hole is 18~25m, and the angle between the drainage hole and the horizontal plane is 8~12°.

[0010] As a further improvement of the present invention, there are multiple drainage holes, and the multiple drainage holes are arranged at a distance of 5-6m along the extension direction of the track, and at a distance of 2-3m along the vertical direction.

[0011] As a further improvement of the present invention, it also includes a counter-pressure layer, which covers the ground plane and partially covers the inclined surface of the support panel and the perimeter of the support structure.

[0012] This application also includes an emergency reinforcement method for railway embankment defects, used to reinforce a retaining structure located on one side of the embankment slope, comprising the following steps: A support panel is attached along the side of the retaining structure away from the embankment slope. Drainage holes are opened in the direction of the slope in the embankment, and the drainage holes extend into the embankment slope and penetrate the retaining structure and the support panel. Anti-slide piles are installed on the side of the support panel away from the embankment slope; A support plate is installed between the support panel and the anti-slide pile, such that one end of the support plate abuts against the support panel and the other end is connected to the anti-slide pile; A counter-pressure layer is covered on the inclined surface of the support panel, with the bottom part of the counter-pressure layer pressing on the support panel and the remaining part pressing on the ground plane.

[0013] As a further improvement of the present invention, observation deformation piles are set at observation points on the rail surface and / or shoulder to detect the horizontal and vertical displacements of the rail surface and / or shoulder.

[0014] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0015] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include: (1) The emergency reinforcement structure for track embankment defects of the present invention, without dismantling the original retaining structure, firstly attaches a support panel to the side of the retaining structure, then sets up a support structure, and sets up a support plate between the support structure and the support panel. The support plate transmits the rolling force on the side of the retaining structure to the support structure, and the support structure transmits the sliding force of the roadbed slope to the ground plane, thereby ensuring the stability of the original retaining structure. The emergency reinforcement structure for track embankment defects in this application sets up a support panel and a support structure without damaging the original retaining structure. This ensures that the existing reinforcement structure can maintain the stable use of the retaining structure, and does not damage the original retaining structure. It avoids the problems of long construction period and secondary collapse during construction caused by damaging the retaining structure, and greatly improves the safety and timeliness of retaining structure repair and treatment.

[0017] (3) The emergency reinforcement structure for track embankment defects of the present invention opens drainage holes along the inclined direction of the embankment slope, and drains the water accumulated in the embankment slope through the drainage holes, thereby improving the stability of the embankment slope, reducing the sliding force of the embankment slope, improving the overall stability of the reinforcement structure, and ensuring the stability of the retaining structure.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0025] Example: Please see Figures 1-3 The emergency reinforcement structure for track embankment defects in the preferred embodiment of the present invention is used to form a reinforcement structure on the retaining structure 1 on one side of the embankment slope 8. It includes a support panel 2 attached to one side of the inclined surface of the retaining structure 1, and a support structure spaced apart from the support panel 2. The support structure extends vertically into the ground plane to fix the support structure. A support plate 3 is also provided between the support panel 2 and the support structure. One end of the support plate 3 abuts against the inclined surface of the support panel 2, and the other end abuts against the support structure to press the support panel 2 against the inclined surface of the retaining structure 1.

[0026] The emergency reinforcement structure for track embankment defects in this application does not remove the original retaining structure 1. Instead, a support panel 2 is installed on the basis of the original retaining structure 1 to support it. Then, a support structure with a certain distance from the support panel 2 is set up, and a support plate 3 is used to connect the support structure and the support panel 2. That is, the force on the retaining structure 1 is transferred to the support panel 2, and then the force on the support panel 2 is transferred to the support structure through the support plate 3. Finally, the support structure transfers the force to the ground plane, forming a stable distribution of the force on the retaining structure 1. By setting up the support panel 2 and the support structure without damaging the original retaining structure 1, it can ensure that the existing reinforcement structure can maintain the stable use of the retaining structure 1, and will not damage the original retaining structure 1. This avoids the problems of long construction period and secondary collapse during construction caused by damaging the retaining structure 1, and greatly improves the safety and timeliness of the repair and treatment of the retaining structure 1.

[0027] Specifically, the side of the inclined surface of the aforementioned retaining structure 1 refers to the side of the retaining structure 1 that is away from the embankment slope 8, and the embankment slope 8, the retaining mechanism, the support panel 2 and the support structure are arranged sequentially along the embankment slope 8 towards the track side.

[0028] Furthermore, as a preferred embodiment of the present invention, the support structure in this application includes anti-slide piles 4 arranged vertically. One end of the anti-slide pile 4 extends into the ground plane, and the other end extends vertically out of the ground plane. One end of the support plate 3 is connected to the anti-slide pile 4, and the other end abuts against the support panel 2. The main body of the support structure in this application is the anti-slide pile 4. The anti-slide pile 4 can be well fixed to the side of the embankment slope 8, forming a stable structure on the ground plane. This facilitates the support plate 3 to transfer the force on the support panel 2 to the anti-slide pile 4, and then the force is transmitted to the ground plane through the anti-slide pile 4.

[0029] Furthermore, as a preferred embodiment of the present invention, there are multiple anti-slip piles 4 in this application, and the multiple anti-slip piles 4 are arranged along the extension direction of the track, and the multiple anti-slip piles 4 are connected as a whole by the cap beam 5; correspondingly, there are also multiple support plates 3 in this application, one end of the multiple support plates 3 abuts against the support panel 2, and the other end abuts against the anti-slip piles 4 one by one. Since the retaining structure 1 is arranged along the track, the reinforcement structure also needs to be arranged along the track. In order to reinforce the overall retaining structure 1, there are multiple anti-slide piles 4 and support plates 3 in this application. The multiple anti-slide piles 4 are connected by the capping beam 5, so that the multiple anti-slide piles 4 form a whole. When a single or individual area of ​​the retaining structure 1 is under stress, the stress on the support panel 2 can be distributed to the capping beam 5 through the support plate 3, and then evenly distributed to each anti-slide pile 4 through the capping beam 5. This greatly improves the overall stress capacity of the reinforcement structure and avoids the problem that the stress on the retaining structure 1 in some areas exceeds the bearing capacity of a single anti-slide pile 4 and causes the overall reinforcement structure to be destroyed.

[0030] Furthermore, as a preferred embodiment of the present invention, the anti-slide pile 4 in this application includes a square column and a bored pile respectively arranged vertically. The square column and the bored pile are integrally arranged, and the cross-section of the square column in the horizontal direction is square, while the cross-section of the bored pile in the horizontal direction is circular. The bored pile is located below the ground plane, and the square column is located above the ground plane. The cross-sectional area of ​​the square column in the horizontal direction is larger than that of the bored pile in the horizontal direction. When the anti-slide pile 4 is set on the ground plane, by setting the anti-slide pile 4 as a multi-segment structure, the cylindrical bored pile facilitates the driving of the anti-slide pile 4 into the ground plane, improving construction efficiency. The platform structure formed by the square column and the bored pile can abut against the ground plane, reducing the probability of the anti-slide pile 4 settling downwards. This ensures that the support panel 2, the support plate 3, and the anti-slide pile 4 form a stable support structure, preventing the support force of the support plate 3 on the support panel 2 from decreasing after the anti-slide pile 4 settles, thus affecting the overall support stability of the reinforcement structure on the retaining structure 1.

[0031] Furthermore, as a preferred embodiment of the present invention, the retaining structure 1 and the supporting panel 2 are provided with at least one drainage hole 6. The drainage hole 6 is arranged along the inclination direction of the embankment slope 8. One end of the drainage hole 6 extends into the inner side of the embankment slope 8, and the other end passes through the retaining structure 1 and the supporting panel 2 to connect the interior of the embankment slope 8 with the exterior. When the embankment collapses due to heavy rainfall, the water remaining in the embankment slope 8 will further loosen the embankment slope 8, causing the collapse of the embankment slope 8 to expand further. This results in the retaining structure 1 and the supporting panel 2 being continuously stressed and gradually strengthened, ultimately leading to the complete damage of the retaining structure 1. To this end, drainage holes 6 are opened in the embankment slope 8. The drainage holes 6 penetrate through both sides of the retaining structure 1 and the support panel 2 to connect the interior of the embankment slope 8 with the outside world, drain the water accumulated on the inside of the embankment slope 8, improve the stability of the embankment slope 8 itself, avoid the embankment slope 8 from continuously putting pressure on the retaining structure 1, and improve the stability support of the reinforcement structure for the retaining structure 1.

[0032] More preferably, the extension depth of the drainage hole 6 is 18~25m, the angle between the drainage hole 6 and the horizontal plane is 8~12°, the overall tilt direction of the drainage hole 6 is the same as the tilt direction of the embankment slope 8, and the way of setting it at a certain angle with the horizontal plane can effectively draw out the water accumulated in the embankment slope 8, so as to improve the stability of the embankment slope 8 itself.

[0033] Furthermore, since the embankment slope 8 also extends along the track line, the drainage holes 6 in this application are also set to be multiple. The multiple drainage holes 6 are arranged at intervals of 5-6m along the track extension direction, which can drain the water accumulated along the embankment slope 8. At the same time, the multiple drainage holes 6 are arranged at intervals of 2-3m along the vertical direction. The drainage holes 6 arranged vertically along the embankment slope 8 can drain water in stages along the vertical direction of the embankment slope 8, thereby improving the drainage efficiency of the water accumulated in the embankment slope 8.

[0034] Furthermore, as a preferred embodiment of the present invention, the emergency reinforcement structure for track embankment defects in this application also includes a counterweight layer 7. The counterweight layer 7 covers the ground plane and partially covers the inclined surface of the support panel 2 and the perimeter of the support structure. Although the support panel 2 is supported and abutted by the support plate 3, the contact area between the support plate 3 and the support panel 2 is relatively small. In order to improve the supporting effect of the support panel 2 on the retaining structure 1, the present application also provides a counterweight layer 7. By partially covering the inclined surface of the support panel 2, the counterweight layer 7 can provide a component force towards the retaining structure 1 to press the support panel 2 firmly against the retaining structure 1. Furthermore, the counterweight layer 7 can also press the circumferential ground plane of the support structure by covering the ground plane, ensuring that the support structure is stably inserted into the ground plane, and facilitating the transmission of the force on the retaining structure 1 to the support structure and the distribution to the ground.

[0035] Preferably, the counterweight layer 7 is composed of rubble or bagged gravel to press the support panel 2 onto the support structure 1 and to compact the ground around the support structure.

[0036] Regarding the aforementioned emergency reinforcement structure for railway embankment defects, this application includes a corresponding emergency reinforcement method for railway embankment defects, comprising the following steps: A support panel 2 is attached to the side of the retaining structure 1 away from the embankment slope 8; A drainage hole 6 is opened in the inclined direction of the embankment slope 8. The drainage hole 6 extends into the embankment slope 8 and penetrates the retaining structure 1 and the support panel 2. Anti-slide piles 4 are installed on the side of the support panel 2 away from the embankment slope 8; A support plate 3 is installed between the support panel 2 and the anti-slide pile 4, such that one end of the support plate 3 abuts against the support panel 2 and the other end is connected to the anti-slide pile 4. A counter-pressure layer 7 is covered on the inclined surface of the support panel 2. The bottom part of the counter-pressure layer 7 is pressed onto the support panel 2, and the remaining part is pressed onto the ground plane.

[0037] This application first sets up a counterweight layer 7 at the retaining structure 1 where the embankment slope 8 is initially damaged or has collapsed, and uses the counterweight layer 7 to backfill the construction site to temporarily reinforce the construction site and prevent the roadbed collapse from expanding further. Then, the support panel 2 is installed, and drainage holes 6 are drilled in the inclined direction of the embankment slope 8. The drainage holes 6 extend into the embankment slope 8 and penetrate the retaining structure 1 and the support panel 2 to facilitate the drainage of accumulated water in the embankment slope 8. Specifically, the drilling depth of the drainage holes 6 is 18~25m, the angle between the drainage holes 6 and the horizontal plane is 8~12°, and there are multiple drainage holes 6. They are arranged at intervals of 5~6m along the track extension direction and at intervals of 2~3m along the vertical direction.

[0038] Furthermore, after the drainage hole 6 is drilled, anti-slip piles 4 are installed on the side of the support panel 2 facing the track. The anti-slip piles 4 are spaced apart from the support panel 2 to facilitate the subsequent installation of the support plate 3. After the anti-slip piles 4 are installed, the support plate 3 is installed. One end of the support plate 3 abuts against the support panel 2, and the other end is connected to the anti-slip piles 4. Finally, the anti-slip piles 4 are connected by the cap beam 5 to form an overall reinforcement structure.

[0039] Furthermore, as an emergency reinforcement method for track embankment defects according to the present invention, the setting of the above-mentioned drainage holes includes repairing the existing surface drainage system, then laying out the positioning lines, drilling holes, checking the drilling quality, and finally installing inclined drainage pipes to form the above-mentioned drainage holes.

[0040] More preferably, the construction of the above-mentioned anti-slide pile 4 includes: surveying and setting out, pile hole excavation, installation of retaining wall formwork, application of retaining wall concrete, hole cleaning, installation of reinforcing cage, pouring of pile body concrete and curing, prefabrication and installation of retaining plate, and finally forming anti-slide pile 4.

[0041] More preferably, the construction of the above-mentioned support panel 2 and support plate 3 includes: laying templates, reserving drainage pipe openings, tying reinforcing bars, pouring concrete and carrying out concrete curing, removing concrete templates, and curing, to form support panel 2 and support plate 3.

[0042] More preferably, the construction of the crown beam 5 includes: chiseling the pile head of the anti-slide pile 4, leveling the top of the anti-slide pile 4, cleaning and straightening the reinforcing bars at the top of the pile, measuring and setting out lines, tying the reinforcing bars of the crown beam 5, erecting formwork, pouring concrete, removing formwork, and curing.

[0043] As part of the emergency reinforcement method for track embankment defects according to the present invention, this application also includes a deformation monitoring system. This system involves setting up observation piles at observation points on the track surface and / or shoulder to detect the horizontal and vertical displacements of the track surface and / or shoulder. The aforementioned deformation monitoring system can detect the vertical and horizontal displacements of the track surface and shoulder during construction. When the displacement rate or cumulative displacement of the track surface and shoulder exceeds a threshold, it indicates a significant risk to the construction, requiring immediate cessation of construction and risk mitigation to ensure construction safety. Simultaneously, this deformation monitoring system can also serve as a subsequent deformation monitoring system for the track system to assess its stability.

[0044] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
