Description

Technical Field

[0001] This utility model relates to the field of subway construction technology, and specifically to a multi-functional support device based on the cross-section of a subway tunnel. Background Technology

[0002] During tunnel construction, support devices are needed to support the tunnel cross-section. Most existing support devices have only one function, which can only support and protect the cross-section and cannot deal with seepage water in the soil layer. This makes the tunnel prone to leakage. In addition, the accumulation of seepage water increases the burden on the support device, which can easily lead to safety risks and also easily cause soil settlement and collapse, thus causing serious safety accidents. Utility Model Content

[0003] To address the technical problems in the prior art, this utility model provides a multifunctional support device based on the cross-section of a subway tunnel, including a support plate and a support frame. The support plate is installed on the top of the tunnel and is fixedly connected to the top of the tunnel through the support frame. The support plate has several through holes spaced apart, and a hollow connecting rod is installed in each through hole. The top end of the connecting rod extends into the soil layer at the top of the tunnel, and the bottom end is located inside the tunnel. Multiple water inlet holes communicating with the inside of the connecting rod are spaced apart on the side wall near the top end of the connecting rod, and a water outlet hole is provided at the bottom end of the connecting rod.

[0004] It also includes multiple flexible guide pipes, each corresponding to a connecting rod. The flexible guide pipes are fixedly installed on the support frame. One end of each flexible guide pipe is located directly below the water outlet, and the other end is connected to the drainage system inside the tunnel. Seepage water flows into the flexible guide pipe through the water outlet and is discharged into the drainage system through the flexible guide pipe.

[0005] Furthermore, a filter screen is provided inside the water inlet, and the filter screen is located at one end near the surface of the connecting rod.

[0006] Furthermore, a guide groove is provided on the side wall of the connecting rod, penetrating the bottom end of the connecting rod, and the guide groove is connected to the water outlet.

[0007] Furthermore, the multi-functional support device based on the subway tunnel cross-section also includes a sleeve, which is fixedly installed on the support frame. The connecting rod is slidably connected to the sleeve. The top end of the sleeve extends through the through hole into the soil layer at the top of the tunnel, and the top end of the sleeve is located below the top end of the connecting rod. A flexible scraper is fixedly installed on the top end of the sleeve, and the flexible scraper slides against the side wall of the connecting rod.

[0008] Furthermore, the bottom end of the sleeve is provided with a first connector, and the bottom end of the connecting rod is provided with a second connector. The first connector and the second connector are connected in series to the control circuit of the alarm. When the second connector is in contact with the first connector, the control circuit is connected and the alarm sounds; otherwise, the control circuit is disconnected and the alarm does not sound.

[0009] Furthermore, the alarm includes a warning light; the warning light illuminates when the control circuit is connected, and de-illuminates when the control circuit is disconnected.

[0010] Beneficial effects:

[0011] 1. In this utility model, the support plate and support frame can effectively support the tunnel cross-section, ensuring construction safety. Combined with the through holes, connecting rods, and flexible guide pipes, seepage water in the soil layer at the top of the tunnel can be guided into the drainage system, avoiding water accumulation and effectively reducing water leakage. At the same time, it can reduce the pressure on the waterproof layer inside the tunnel and improve the reliability of the waterproof system. In specific use, firstly, a corresponding support plate is designed according to the shape and size of the tunnel cross-section, and multiple through holes are opened on the support plate. Then, the support plate is installed and fixed to the top of the tunnel through the support frame. Next, the connecting rod is inserted through the through holes into the top of the tunnel, ensuring that the water inlet holes are all located inside the soil layer. At the same time, the water outlet holes protrude outside the support plate and are connected to the drainage system inside the tunnel through the flexible guide pipe. Through the water inlet holes and water outlet holes, seepage water in the soil layer at the top of the tunnel can be introduced into the drainage system through the flexible guide pipe.

[0012] 2. In this utility model, the filter screen can prevent impurities from entering the water inlet or connecting rod, thus preventing blockage; the guide channel can improve the flow guiding effect, accelerate the discharge of accumulated water, and further reduce water leakage.

[0013] 3. In this utility model, the sleeve, flexible scraper, and the sliding connection between the sleeve and the connecting rod enable the soil layer adhering to the surface of the connecting rod to be cleaned by moving the connecting rod up and down, preventing the water inlet from being blocked. In specific use, when the water flow at the water outlet of the connecting rod is significantly reduced or even absent, the connecting rod can be pulled up and down to make the top of the connecting rod slide inside the sleeve, and the flexible scraper at the top of the sleeve can be used to scrape off the soil layer on the periphery of the connecting rod.

[0014] 4. In this utility model, the inclusion of a first connector, a second connector, a control circuit, and an alarm allows for the detection of displacement of the connecting rod by checking if the alarm is triggered. This enables the monitoring of settlement and collapse within the soil layer at the top of the tunnel, further ensuring construction safety. Specifically, when settlement and collapse occur, the connecting rod at the corresponding position will move down with the soil layer, causing the second connector to contact the first connector and activating the control circuit. Combined with the warning light, the light can alert construction personnel, enhancing the warning effect. Attached Figure Description

[0028] This utility model provides a multifunctional support device based on the cross-section of a subway tunnel, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the system includes a support plate 1 and a support frame 2. The support plate 1 is installed on the top of the tunnel and is fixedly connected to the top of the tunnel through the support frame 2. Specifically, the support frame 2 can be fixedly connected to both sides of the tunnel. The support plate 1 has several through holes spaced apart. A hollow connecting rod 3 is installed in each through hole. The top end of the connecting rod 3 extends into the soil layer at the top of the tunnel, and the bottom end is located inside the tunnel. To prevent soil or seepage water from entering the tunnel through the gap between the through holes and the connecting rod 3, a sealing structure can be set at the gap. The side wall of the connecting rod 3 near the top end has several water inlet holes 4 spaced apart, which connect to the inside of the connecting rod 3. To facilitate seepage water entering the connecting rod 3 through the water inlet holes 4, the water inlet holes 4 can be set as funnel-shaped and inclined upwards towards the soil layer, or the connecting rod 3 can be set as a conical structure, and it is ensured that the top dimension of the connecting rod 3 is smaller than the bottom dimension. The bottom end of the connecting rod 3 has a water outlet hole 5.

[0029] It also includes multiple flexible guide pipes 6, each corresponding to a connecting rod 3. The flexible guide pipes 6 are fixedly installed on the support frame 2. One end of each flexible guide pipe 6 is connected to the water outlet 5, and the other end is connected to the drainage system inside the tunnel. Seepage water flows into the flexible guide pipe 6 through the water outlet 5 and is discharged into the drainage system through the flexible guide pipe 6. In actual installation, the flexible guide pipe 6 can be suspended and connected to the water outlet 5, that is, the water droplets discharged from the water outlet 5 fall on the inlet end of the flexible guide pipe 6. Alternatively, it can be directly connected through a flexible hose.

[0030] In this embodiment, the support plate 1 and support frame 2 can effectively support the tunnel cross-section, ensuring construction safety. Combined with the through holes, connecting rods 3 and flexible guide pipes 6, seepage water in the soil layer at the top of the tunnel can be guided into the drainage system, avoiding water accumulation and effectively reducing water leakage. At the same time, it can reduce the pressure on the waterproof layer inside the tunnel and improve the reliability of the waterproof system. In specific use, firstly, the support plate 1 is designed according to the shape and size of the tunnel cross-section, and multiple through holes are opened on the support plate 1. Then, the support plate 1 is installed and fixed to the top of the tunnel through the support frame 2. Next, the connecting rod 3 is inserted through the through holes into the top of the tunnel, ensuring that the water inlet holes 4 are all located inside the soil layer. At the same time, the water outlet holes 5 are exposed outside the support plate 1 and connected to the drainage system inside the tunnel through the flexible guide pipe 6. Through the water inlet holes 4 and the water outlet holes 5, seepage water in the soil layer at the top of the tunnel can be introduced into the drainage system through the flexible guide pipe 6.

[0031] In this utility model, preferably, such as Figure 2 and Figure 4 As shown, a filter screen is provided inside the water inlet 4, and the filter screen is located at one end near the surface of the connecting rod 3.

[0032] In this embodiment, the filter screen can prevent impurities from entering the water inlet 4 or the connecting rod 3, thus preventing blockage.

[0033] In this utility model, preferably, such as Figure 2 and Figure 4 As shown, a guide groove 7 is provided on the side wall of the connecting rod 3, which penetrates the bottom end of the connecting rod 3, and the guide groove 7 is connected to the water outlet 5.

[0034] In this embodiment, the flow channel 7 can improve the flow guidance effect, accelerate the discharge of accumulated water, and further reduce water leakage.

[0035] In this utility model, preferably, such as Figure 1 , Figure 2 and Figure 4 As shown, the multi-functional support device based on the subway tunnel cross-section also includes a sleeve 8, which is fixedly installed on the support frame 2. The connecting rod 3 is slidably connected to the sleeve 8. The top end of the sleeve 8 extends through the through hole into the soil layer at the top of the tunnel, and the top end of the sleeve 8 is located below the top end of the connecting rod 3. A flexible scraper 9 is fixedly installed on the top end of the sleeve 8, and the flexible scraper 9 slides against the side wall of the connecting rod 3.

[0036] In this embodiment, the sleeve 8, the flexible scraper 9, and the sliding connection between the sleeve 8 and the connecting rod 3 allow the soil layer adhering to the surface of the connecting rod 3 to be cleaned by moving the connecting rod 3 up and down, preventing the water inlet hole 4 from being blocked. Specifically, when the water flow at the water outlet hole 5 of the connecting rod 3 is significantly reduced or even absent, the connecting rod 3 can be pulled up and down to make the top end of the connecting rod 3 slide inside the sleeve 8, and the flexible scraper 9 at the top end of the sleeve 8 can be used to scrape off the soil layer on the circumference of the connecting rod 3.

[0037] In this utility model, preferably, such as Figure 2 and Figure 4 As shown, the bottom end of the sleeve 8 is provided with a first connector 10, and the bottom end of the connecting rod 3 is provided with a second connector 11. The first connector 10 is located below the second connector 11. The first connector 10 and the second connector 11 are connected in series to the control circuit of the alarm. When the second connector 11 is in contact with the first connector 10, the control circuit is connected and the alarm sounds; otherwise, the control circuit is disconnected and the alarm does not sound. The alarm includes a warning light. When the control circuit is connected, the warning light is lit; when the control circuit is disconnected, the warning light is not lit.

[0038] In this embodiment, by setting up the first connector 10, the second connector 11, the control circuit, and the alarm, it is possible to confirm whether the connecting rod 3 has shifted by whether the alarm is triggered, thereby monitoring the settlement and collapse in the soil layer at the top of the tunnel, and further ensuring construction safety. Specifically, when settlement and collapse occur, the connecting rod 3 at the corresponding position will move down with the soil layer, so that the second connector 11 contacts the first connector 10 and connects the control circuit; combined with the setting of the warning light, it is possible to remind construction personnel through light, thereby improving the warning effect.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
