Description

Technical Field

[0001] This utility model belongs to the field of urban planning technology, and in particular relates to an underground utility tunnel support structure for urban integrated underground utility tunnels. Background Technology

[0002] In the field of urban planning, underground utility tunnels, as core infrastructure for the centralized collection of various pipelines, directly determine the safety and efficiency of urban infrastructure through their long-term structural stability.

[0003] Chinese patent CN223226681U discloses an underground integrated utility tunnel for urban planning and design. By setting movable partitions, the chamber area can be flexibly adjusted. Combined with structural steel and support mechanism (including support plate, support rod and rope), it alleviates the problem of uneven lateral pressure in the utility tunnel caused by the movement of partitions. At the same time, the connection design between structural steel and cavity improves the ventilation conditions inside the utility tunnel, thereby improving the practicality and structural stability of the utility tunnel to a certain extent.

[0004] The aforementioned patent has the following problems: This patent has several drawbacks in its application. Firstly, it only uses the threaded connection between the threaded rod and the partition to initially define the partition's position. After the partition moves to the target position, it relies on the threaded friction of the threaded rod to maintain its position, lacking a mechanical locking or support reinforcement structure at the bottom. When one chamber bears a significant amount of pipeline weight, the bottom of the partition is prone to tilting due to uneven stress, which not only compromises the dimensional stability of the chamber but also causes stress imbalance in structural steel, springs, and other supporting components, leading to localized deformation of the utility tunnel. Therefore, we propose an underground utility tunnel support structure for urban integrated underground utility tunnels. Utility Model Content

[0005] The purpose of this utility model is to provide an underground utility tunnel support structure for urban integrated underground utility tunnels, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides an underground utility tunnel support structure for an urban integrated underground utility tunnel, including a utility tunnel body, an inner channel provided inside the utility tunnel body, a partition slidably installed on the inner wall of the inner channel, and a plurality of positioning grooves opened on the lower side of the inner channel; Multiple support feet are provided, each corresponding to one or both sides of the partition. An outer tube is fixedly installed at the bottom of each support foot. An inner tube is slidably installed on the inner wall of the outer tube. Two telescopic holes are formed on the surface of the inner tube. A positioning block is slidably installed in each of the two telescopic holes. A positioning hole is formed on the inner wall of the positioning groove, and the positioning hole corresponds to the positioning block. A sliding block is fixedly installed on the opposite face of each of the two positioning blocks. A connecting rod is rotatably installed on the upper side of each of the two sliding blocks. The same connector is rotatably installed on the top of each of the two connecting rods. A fixing bolt is rotatably installed on the upper side of the connector, and the top of the fixing bolt extends to the upper side of the outer tube.

[0007] In this technical solution, the main body of the pipe gallery has an internal channel to accommodate pipelines. A partition is slidably installed on the inner wall of the internal channel to flexibly divide the space. Multiple positioning grooves are formed along the length of the inner bottom wall of the internal channel. Two support feet are installed on both sides of the partition, and an outer pipe is fixedly installed at the bottom of the support feet. An inner pipe is slidably installed on the inner wall of the outer pipe, allowing it to extend and retract relative to the outer pipe. Two opposing expansion holes are formed on the surface of the inner pipe, and positioning blocks are slidably installed in each of the two expansion holes. Positioning holes are formed on the inner wall of the positioning grooves, their positions corresponding to the positioning blocks. Sliding blocks are fixedly installed on the opposite faces of the two positioning blocks, and connecting rods are rotatably installed on the upper sides of the two sliding blocks via a rotating shaft. The tops of the two connecting rods are rotatably mounted with the same connector. A fixing bolt is rotatably installed on the upper side of the connector via a thread. The top of the fixing bolt extends to the upper side of the outer pipe for operation. When the partition moves into position, its bottom support feet and outer pipe are aligned with a positioning groove below. The operator manually presses down on the fixing bolt, causing the inner tube to extend downwards from the outer tube and insert into the positioning groove. When the inner tube moves to a certain depth and its positioning block aligns with the positioning hole on the side wall of the positioning groove, the operator maintains downward pressure and rotates the fixing bolt clockwise. The fixing bolt screws down, pushing the connector downwards. As the connector moves downwards, it forces the lower ends of the two connecting rods to open outwards, thereby pushing the two sliding blocks to slide back and forth within the telescopic hole. Finally, it pushes the two positioning blocks out of the inner tube and firmly inserts them into the positioning hole of the positioning groove, forming a mechanical interlock. At the same time, the head of the fixing bolt presses against the upper end of the outer tube, securing the entire support leg system to the bottom wall of the inner channel. This ensures even force distribution at the bottom of the partition, effectively resisting the overturning moment caused by uneven weight distribution on one side of the pipeline, and ensuring the stability of the chamber dimensions.

[0008] In the above technical solution, a return spring is further fixedly installed between the inner tube and the outer tube, and the return spring is sleeved on the surface of the fixing bolt.

[0009] In this technical solution, when it is necessary to unlock, the fixing bolt is rotated counterclockwise to raise it, releasing the tension of the connecting rod, and the positioning block retracts under the action of the internal mechanism. At this time, the elastic force of the return spring will pull the inner tube upward back into the outer tube, causing the bottom of the support foot to disengage from the positioning groove, making it easier for the partition to move again, thus facilitating partition movement and reducing the effort required for operation.

[0010] In the above technical solution, a top spring is fixedly installed on the inner bottom wall of the positioning groove, and a dust cover is fixedly installed on the top of the top spring, with the dust cover fitting inside the positioning groove.

[0011] In this technical solution, a top spring is fixedly installed on the inner bottom wall of the positioning groove. A dust cover is fixedly installed on the top of the top spring; the dust cover fits against the uppermost part of the positioning groove in its natural state. When the inner tube is not inserted, the dust cover closes the positioning groove under the action of the top spring, preventing dust and debris from falling into the groove. When the inner tube is pressed down and inserted, the dust cover will first be pressed open, compressing the top spring and exposing the positioning hole for locking, preventing foreign objects from blocking the positioning groove and positioning hole, and ensuring the reliability and service life of the locking mechanism.

[0012] In the above technical solution, a drive screw is rotatably mounted on the inner wall of the inner channel, the partition is slidably mounted on the surface of the drive screw, and a drive motor is fixedly mounted on the inner wall of the inner channel. The output end of the drive motor is coaxially and fixedly connected to one end of the drive screw.

[0013] In this technical solution, the drive motor rotates, which in turn drives the drive screw to rotate. Since the partition and the screw are threaded together, and their movement is restricted by the track and cannot rotate, the rotation of the screw is converted into precise linear movement of the partition along the inner channel.

[0014] In the above technical solution, X-shaped reinforcing ribs are fixedly installed on both sides of the inner channel, and mesh reinforcing ribs are fixedly installed on both the upper and lower sides of the inner channel. The X-shaped reinforcing ribs and mesh reinforcing ribs are located between the main body of the pipe gallery and the inner channel.

[0015] In this technical solution, X-shaped and mesh-shaped reinforcing bars are embedded in the wall of the utility tunnel and are cast or welded integrally with the main structure. The X-shaped bars effectively resist lateral earth pressure and deformation, while the mesh-shaped bars enhance the bending and shear resistance of the top and bottom slabs, thus significantly improving the load-bearing capacity and seismic performance of the utility tunnel.

[0016] In the above technical solution, furthermore, support blocks are fixedly installed on both sides of the partition, and the upper sides of the two support blocks are attached to the upper side of the inner channel.

[0017] In this technical solution, once the partition is installed in place, its top support block will fit tightly against the top plate of the inner channel, forming an upper support point.

[0018] In the above technical solution, the area where the support foot connects to the partition has a certain angle.

[0019] In this technical solution, the support area is increased to improve support stability.

[0020] The beneficial effects of this utility model are: The underground utility tunnel support structure of this urban integrated underground utility tunnel is constructed by manually pressing the fixing bolts. The fixing bolts drive the inner tube downwards, first squeezing the dust cover, causing the dust cover to move downwards and stretching the return spring and the compression top spring. When the top spring is pressed to its maximum position, the positioning block positions the positioning hole. At this time, the pressing posture is maintained while the fixing bolt is rotated synchronously, and the fixing bolt moves downwards in the inner tube. The fixing bolt drives the connecting piece downwards, and the connecting piece simultaneously drives the two connecting rods to unfold. The two connecting rods drive the corresponding sliding blocks to move, causing the two sliding blocks to move away from each other. The two sliding blocks drive the corresponding positioning blocks to extend into the positioning holes, completing the positioning of the inner tube. At the same time, the fixing bolt also fixes the outer tube to the inner bottom wall of the inner channel, thereby completing the fixation of the support feet and thus completing the positioning of the bottom of the partition, achieving the effect of fixing the bottom of the partition.

[0025] Example 1: This example provides an underground utility tunnel support structure for an urban integrated underground utility tunnel, including a utility tunnel body 1, an inner passage 2 inside the utility tunnel body 1, a partition 4 slidably installed on the inner wall of the inner passage 2, and multiple positioning grooves 3 opened on the lower side of the inner passage 2. Multiple support feet 10 are fixedly installed on both sides of the partition plate 4. An outer tube 11 is fixedly installed at the bottom of the support foot 10. An inner tube 12 is slidably installed on the inner wall of the outer tube 11. Two telescopic holes are opened on the surface of the inner tube 12. A positioning block 15 is slidably installed in each of the two telescopic holes. A positioning hole is opened on the inner wall of the positioning groove 3. The positioning hole corresponds to the positioning block 15. A sliding block 14 is fixedly installed on the opposite side of the two positioning blocks 15. A connecting rod 13 is rotatably installed on the upper side of the two sliding blocks 14. The same connector 20 is rotatably installed on the top of the two connecting rods 13. A fixing bolt 19 is rotatably installed on the upper side of the connector 20. The top of the fixing bolt 19 extends to the upper side of the outer tube 11.

[0026] The main body 1 of the pipe gallery has an internal passageway 2 for accommodating pipelines. A partition 4 is slidably installed on the inner wall of the internal passageway 2 to flexibly divide the space. Multiple positioning grooves 3 are formed along the length of the inner bottom wall of the internal passageway 2. Two support feet 10 are installed on both sides of the partition 4. An outer pipe 11 is fixedly installed at the bottom of the support feet 10. An inner pipe 12 is slidably installed on the inner wall of the outer pipe 11, allowing it to extend and retract relative to the outer pipe 11. Two opposing expansion holes are formed on the surface of the inner pipe 12, and positioning blocks 15 are slidably installed in each of the two expansion holes. Positioning holes are formed on the inner wall of the positioning grooves 3, their positions corresponding to the positioning blocks 15. Sliding blocks 14 are fixedly installed on the opposing surfaces of the two positioning blocks 15. Connecting rods 13 are rotatably installed on the upper sides of the two sliding blocks 14 via a rotating shaft. The top ends of the two connecting rods 13 are rotatably mounted with the same connector 20. A fixing bolt 19 is rotatably installed on the upper side of the connector 20 via a threaded connection. The top of the fixing bolt 19 extends to the upper side of the outer tube 11 for operation; when the partition 4 is moved into place, its bottom support foot 10 and the outer tube 11 are aligned with a positioning groove 3 below. The operator manually presses the fixing bolt 19 downward, causing the inner tube 12 to extend downward out of the outer tube 11 and insert into the positioning groove 3. When the inner tube 12 moves down to a certain depth and the positioning block 15 on it aligns with the positioning hole on the side wall of the positioning groove 3, the operator maintains downward pressure and rotates the fixing bolt 19 clockwise. The fixing bolt 19 is screwed downward, pushing the connector 20 downward. When the connector 20 moves downward, it forces the lower ends of the two connecting rods 13 to open outward, thereby pushing the two sliding blocks 14 to slide in opposite directions within the telescopic hole, ultimately pushing the two positioning blocks 15 out of the inner tube 12 and firmly inserting them into the positioning hole of the positioning groove 3, forming a mechanical interlock. At the same time, the head of the fixing bolt 19 will press against the upper end of the outer tube 11, and fasten the entire support leg 10 system to the inner bottom wall of the inner channel 2, so that the bottom of the partition 4 is evenly stressed, effectively resisting the overturning moment caused by the uneven weight of the pipeline on one side, and ensuring the stability of the chamber size.

[0027] Example 2: This example provides an underground utility tunnel support structure for an urban integrated underground utility tunnel. In addition to the technical solutions of the above examples, it also has the following technical features: a return spring 16 is fixedly installed between the inner tube 12 and the outer tube 11, and the return spring 16 is sleeved on the surface of the fixing bolt 19.

[0028] When the locking mechanism needs to be released, rotating the fixing bolt 19 counterclockwise causes it to rise, releasing the tension of the connecting rod 13, and causing the positioning block 15 to retract under the action of the internal mechanism. At this time, the elastic force of the return spring 16 will pull the inner tube 12 upward back into the outer tube 11, causing the bottom of the support foot 10 to disengage from the positioning groove 3, making it easier for the partition 4 to move again, thus facilitating the movement of the partition 4 and reducing the effort required for operation.

[0029] Example 3: This example provides an underground utility tunnel support structure for an urban integrated underground utility tunnel. In addition to the technical solutions of the above examples, it also has the following technical features: a top spring 17 is fixedly installed on the inner bottom wall of the positioning groove 3, and a dust cover 18 is fixedly installed on the top of the top spring 17. The dust cover 18 fits into the positioning groove 3.

[0030] A top spring 17 is fixedly installed on the inner bottom wall of the positioning groove 3. A dust cover 18 is fixedly installed on the top of the top spring 17. In its natural state, the dust cover 18 fits against the uppermost part of the positioning groove 3. When the inner tube 12 is not inserted, the dust cover 18 closes the positioning groove 3 under the action of the top spring 17 to prevent dust and debris from falling into the groove. When the inner tube 12 is pressed down and inserted, the dust cover 18 will be pressed open first, compressing the top spring 17 and exposing the positioning hole for locking, preventing foreign objects from blocking the positioning groove 3 and the positioning hole, and ensuring the reliability and service life of the locking mechanism.

[0031] Example 4: This example provides an underground utility tunnel support structure for an urban integrated underground utility tunnel. In addition to the technical solutions of the above examples, it also has the following technical features: a drive screw 8 is rotatably installed on the inner wall of the inner channel 2, a partition 4 is slidably installed on the surface of the drive screw 8, and a drive motor 9 is fixedly installed on the inner wall of the inner channel 2. The output end of the drive motor 9 is coaxially and fixedly connected to one end of the drive screw 8.

[0032] The drive motor 9 rotates, causing the drive screw 8 to rotate. Since the partition 4 and the screw are threaded together and its movement is restricted by the track, the rotation of the screw is converted into precise linear movement of the partition 4 along the inner channel 2.

[0033] Example 5: This example provides an underground utility tunnel support structure for an urban integrated underground utility tunnel. In addition to the technical solutions of the above examples, it also has the following technical features: X-shaped reinforcing ribs 6 are fixedly installed on both sides of the inner passage 2, and mesh reinforcing ribs 7 are fixedly installed on both the upper and lower sides of the inner passage 2. The X-shaped reinforcing ribs 6 and the mesh reinforcing ribs 7 are located between the main body 1 of the utility tunnel and the inner passage 2.

[0034] Among them, the X-shaped and mesh-shaped reinforcing bars 7 are embedded in the wall of the pipe gallery and are cast or welded together with the main structure. The X-shaped bars effectively resist lateral earth pressure and deformation, while the mesh-shaped bars enhance the bending and shear resistance of the top and bottom plates, thus significantly improving the load-bearing capacity and seismic performance of the main pipe gallery 1.

[0035] Example 6: This example provides an underground utility tunnel support structure for an urban integrated underground utility tunnel. In addition to the technical solutions of the above examples, it also has the following technical features: support blocks 5 are fixedly installed on both sides of the partition 4, and the upper sides of the two support blocks 5 are attached to the upper side of the inner passage 2.

[0036] When the partition 4 is installed in place, its top support block 5 will be in close contact with the top plate of the inner channel 2, forming an upper support point.

[0037] Example 7: This example provides an underground utility tunnel support structure for an urban integrated underground utility tunnel. In addition to the technical solutions of the above examples, it also has the following technical features: the connection area between the support leg 10 and the partition plate 4 has a certain angle.

[0038] This includes increasing the support area to improve support stability.

[0039] Working principle: When the device is in use, the drive motor 9 is started, and the output end of the drive motor 9 drives the drive screw 8 to rotate. The drive screw 8 drives the partition 4 to move horizontally, thereby adjusting the space of the inner channel 2. After adjustment, make fine adjustments to ensure that the outer tube 11 is directly below the positioning groove 3. Then, manually press the fixing bolt 19. The fixing bolt 19 drives the inner tube 12 to move downward. The inner tube 12 first squeezes the dust cover 18, causing the dust cover 18 to move downward and stretch the return spring 16 and the compression top spring 17. When the top spring 17 is pressed down to its maximum position, the positioning block 15 positions the positioning hole. At this time, maintain the downward pressing posture and rotate the fixing bolt 19 synchronously. The fixing bolt 19 moves downward in the inner tube 12. The fixing bolt 19 drives the connecting piece 20 to move downward. The connecting piece 20 simultaneously drives the two connecting rods 13 to unfold. The two connecting rods 13 drive the corresponding sliding block 14 to move, causing the two sliding blocks 14 to move away from each other. The two sliding blocks 14 drive the corresponding positioning block 15 to extend into the positioning hole, completing the positioning of the inner tube 12. At this time, the fixing bolt 19 also fixes the outer tube 11 to the inner bottom wall of the inner channel 2, thereby completing the fixing of the support foot 10 and thus completing the positioning of the bottom of the partition 4. When adjustments are needed, simply rotate the fixing bolt 19 in the opposite direction to retract the two positioning blocks 15, and use the top spring 17 to drive the dust cover 18 to push the inner tube 12 out of the positioning groove 3, and use the reset spring 16 to pull the inner tube 12 into the interior of the outer tube 11 to release the positioning.
