Description

Technical Field

[0001] The present invention relates to the technical field of integrated pipe corridor construction, and in particular to a positioning construction system and a construction method for a prefabricated integrated pipe corridor under a large longitudinal slope. Background Art

[0002] Traditional direct buried pipelines occupy a lot of underground space in roads. At the same time, the laying of pipelines often cannot be synchronized with road construction, resulting in frequent road excavation. This not only seriously affects the normal traffic on the road, but also brings serious environmental pollution problems such as noise and dust. Therefore, a comprehensive pipeline corridor structure has emerged for laying underground pipelines.

[0003] In order to improve the overall structure and quality of the integrated pipe gallery, currently, pipe gallery segments are prefabricated in standardized factories first, and then uniformly transported to the foundation pit for positioning and splicing. During splicing, hoisting equipment is often used to hang the pipe gallery segments to be spliced, and the pipe gallery segments are positioned and installed by manual labor. However, under the installation conditions of large longitudinal slopes, such as Figure 8 As shown, since the installed tunnel segment 1 is inclined along the large longitudinal slope, and the hoisted tunnel segment 1 always remains horizontal due to the action of gravity, there is a certain angle between the two tunnel segments 1 that need to be spliced. Using manual positioning and installation is not only time-consuming and labor-intensive, but also cannot guarantee the accuracy of assembly. Summary of the Invention

[0004] In response to the deficiencies in the prior art, the present invention provides a positioning construction system and method for prefabricated integrated pipeline corridors under large longitudinal slopes, which solves the problem in the prior art that when installing pipeline corridor segments under large longitudinal slopes, manual positioning and installation are not only time-consuming and labor-intensive, but also cannot guarantee the accuracy of assembly.

[0014] The pushing member is provided on the supporting plate and is used to push the pipe gallery segment located on the supporting plate so that it moves along the length direction of the supporting plate.

[0015] Preferably, the pushing member includes a pushing plate slidably arranged on the supporting plate and a second telescopic member arranged on one side of the supporting plate, and the second telescopic member is connected to the pushing plate.

[0016] Preferably, a plurality of anti-slip grooves are provided on the supporting plate.

[0018] The positioning plate and the bearing plate are provided with two limit frames, and the two positioning plates are slidably arranged on the two limit frames respectively;

[0019] The rotating part has protrusions at both ends movably provided with linkage rods, and the two linkage rods are movably connected to the two positioning plates respectively;

[0020] The first telescopic member is arranged at one end of the bearing plate and is connected to one of the positioning plates thereof, and is used for controlling the two positioning plates to move closer to or farther away from each other.

[0021] Preferably, a plurality of rollers are provided on the positioning plate, and the rollers are slidably fitted with the sides of the pipe gallery segment.

[0022] Preferably, the walking unit includes:

[0023] Slide track;

[0024] The two bearing frames are respectively arranged at both ends of the bearing plate and are provided with a power pulley group, and the power pulley group is mounted on the sliding track.

[0025] On the other hand, according to an embodiment of the present invention, the present invention also provides a construction method for a prefabricated integrated pipe gallery under a large longitudinal slope, comprising the following steps:

[0026] Transporting each pipe gallery segment: Use lifting equipment to lift each pipe gallery segment in sequence to the base cushion layer in the large longitudinal slope foundation pit;

[0027] Install the pipe gallery segment at the lowest point of the large longitudinal slope: hoist the first pipe gallery segment to the lowest point in the foundation pit on the large longitudinal slope, adjust it to the middle of the base cushion layer, and cast a pier at one end of the base cushion layer to abut the first pipe gallery segment;

Then the adjacent pipe gallery segment (such as the second segment) is installed. The bearing plate is moved to this pipe gallery segment by the walking unit, and the pipe gallery segment is lifted by the supporting unit to separate it from the base cushion layer. Since the pipe gallery segment is not subjected to the vertical upward suspension force, the direction of the supporting force at its bottom is always perpendicular to the base cushion layer, so that the pipe gallery segment always corresponds to the first pipe gallery segment at each stage, and the two pipe gallery segments are no longer aligned manually, which not only saves manpower but also initially guarantees Improved accuracy; after the second section of the corridor segment is transported to the side of the first section of the corridor segment under the action of the walking unit and the supporting unit, the position of the second section of the corridor segment can be adjusted by pressing with the cooperation of the positioning unit, so that the axis of the second section of the corridor segment is collinear with the axis of the first section of the corridor segment, that is, the final positioning is completed. In this way, the accuracy of the docking of the two corridor segments is effectively improved. Finally, under the limit of the positioning unit, the second section of the corridor segment is moved to the first section of the corridor segment for docking. The present application can be used to quickly and accurately dock the corridor segments placed in a large longitudinal slope foundation pit, saving manpower and time.

[0042] The technical solutions of the present invention are further described below with reference to the accompanying drawings and embodiments.

[0043] like Figures 1 to 7 As shown, the embodiment of the present invention proposes a positioning construction system for a prefabricated integrated pipe gallery under a large longitudinal slope, which is used to install a pipe gallery segment 1, comprising:

[0044] The bearing plate 5 is located on the top of the pipe gallery segment 1;

[0045] The supporting unit is provided on the bearing plate 5 and is located on both sides of the pipe gallery segment 1, and is used to support the pipe gallery segment 1 to move closer to or away from the bearing plate 5;

[0046] Positioning units are provided on the bearing plate 5 and are also located on both sides of the pipe gallery segment 1 so that the axial direction of the pipe gallery segment 1 is parallel to the width direction of the bearing plate 5; and

[0047] The walking unit is provided on the bearing plate 5 so that the supporting unit carries the pipe gallery segment 1 to move.

[0048] In this embodiment, a base cushion layer 2 can be cast in the foundation pit before construction to prevent foundation collapse and to provide stable support for the subsequent pipeline corridor segment 1, and the walking unit is laid in the foundation pit, i.e., on both sides of the base cushion layer 2. After the base cushion layer 2 is formed, the prefabricated pipeline corridor segments 1 that need to be constructed can be lifted to the large longitudinal slope section in turn through lifting equipment (not shown in the figure), and the first pipeline corridor segment 1 is placed at the lowest point of the large longitudinal slope section and adjusted to the middle of the base cushion layer 2. The piers are cast at the lowest point of the base cushion layer 2 to abut the first pipeline corridor segment 1 to prevent displacement during docking construction, and the installation of the first pipeline corridor segment 1 is completed.

[0049] In order to facilitate construction under conditions of large longitudinal slopes, each pipeline gallery segment 1 is installed one by one in a bottom-up manner. For example, but not limited to, when the second pipeline gallery segment 1 is connected to the first pipeline gallery segment 1, the bearing plate 5 is moved to the second pipeline gallery segment 1 by the walking unit. In order to facilitate the movement of the second pipeline gallery segment 1, the second pipeline gallery segment 1 can be separated from the base cushion layer 2 under the action of the supporting unit. Since the walking unit is directly laid in the foundation pit, the supporting unit always moves along the direction of the large longitudinal slope of the foundation pit. When the second pipeline gallery segment 1 is transported to the side of the first pipeline gallery segment 1, the second pipeline gallery segment 1 is lowered so that it is located on the base cushion layer 2.

[0050] However, the mouth of the second tunnel segment 1 is not precisely opposite to the first tunnel segment 1, so at this time, with the cooperation of the positioning unit, by pressing the two sides of the second tunnel segment 1, the second tunnel segment 1 is rotated by itself until the side of the second tunnel segment 1 is aligned with the side of the first tunnel segment 1, and the final precise positioning is completed. Pushing the second tunnel segment 1 can connect and close the sealed docking interfaces of the two tunnel segments 1. In the subsequent docking operation of two adjacent tunnel segments 1, the above steps can be repeated, which saves manpower and time, and also ensures the accuracy of docking, and is less likely to cause collision.

[0051] The lifting unit includes:

[0052] The two fixing frames 21 are respectively arranged on both sides of the load-bearing plate 5, and are both slidably sleeved with a supporting plate 17, and the supporting plate 17 is provided with a plurality of anti-slip grooves 16;

[0053] The rotating rod 20 is rotatably mounted on the fixing frame 21 and passes through the supporting plate 5. The bottom end of the rotating rod 20 is provided with a threaded section 18, and the supporting plate 17 is engaged with the threaded section 18.

[0054] The transmission member 8 is connected to the driving rod 7. One end of the driving rod 7 and the top end of the rotating rod 20 are both provided with a bevel gear 6, and the two bevel gears 6 are meshed; and

[0055] The pushing member is provided on the supporting plate 17 and is used to push the pipe gallery segment 1 located on the supporting plate 17 so that it moves along the length direction of the supporting plate 17.

[0056] The pushing member includes a pushing plate 15 slidably arranged on the supporting plate 17 and a second telescopic member 19 arranged on one side of the supporting plate 17 . The second telescopic member 19 is connected to the pushing plate 15 .

[0057] In this embodiment, Figure 4 As shown, specifically, when the pipe gallery segment 1 to be supported is lifted or lowered by the lifting unit, the transmission member 8 is started, so that the transmission member 8 synchronously drives the two connected driving rods 7 to rotate, thereby rotating the bevel gear 6 at one end of the driving rod 7, and because the bevel gear 6 at one end of the driving rod 7 is engaged with the bevel gear 6 at the top of the rotating rod 20, the driving rod 7 can synchronously drive the rotating rod 20 to rotate, and the rotating rod 20 is controlled to rotate forward and reverse by the forward and reverse rotation of the transmission member 8, so that the lifting plate 17 can be lifted and lowered on the threaded section 18 of the rotating rod 20 and the fixing frame 21, thereby completing the lifting or lowering of the pipe gallery segment 1; Secondly, a number of anti-slip grooves 16 are also provided on the lifting plate 17, which can increase the friction between the corridor segment 1 and the lifting plate 17, and avoid self-displacement and tilting during transportation; furthermore, in order to further reduce manpower input, with the cooperation of the pushing member, the corridor segment 1 is transported to the side of the corridor segment 1 that has been installed and put down through the lifting plate 17. Since all the positioning work has been completed, the second telescopic member 19 can be directly started to shrink its telescopic end and drive the pushing plate 15 to move in the lifting plate 17, thereby pushing the corridor segment 1 towards the corridor segment 1 that has been installed until the docking is successful.

[0058] The positioning unit includes:

[0059] The positioning plate 14 and the supporting plate 5 are provided with two limiting frames 10, and the two positioning plates 14 are respectively slidably provided on the two limiting frames 10;

[0060] The rotating member 12 has two end protrusions movably provided with linkage rods 11, and the two linkage rods 11 are movably connected to the two positioning plates 14 respectively;

[0061] The first telescopic member 9 is provided at one end of the supporting plate 5 and is connected to one of the positioning plates 14 thereof, and is used for controlling the two positioning plates 14 to move closer to or farther from each other.

[0062] A plurality of rollers 13 are provided on the positioning plate 14 , and the rollers 13 are slidably fitted with the side surfaces of the pipe gallery segment 1 .

[0063] In this embodiment, since each pipe gallery segment 1 cannot be guaranteed to be completely aligned with the first pipe gallery segment 1 during the process of being suspended, most of them have slight deviations. Whether the pipe gallery segment 1 is still on the supporting plate 17 or has been lowered to the base layer 2 through the supporting plate 17, it can be positioned by the positioning unit, such as Figure 3 As shown, when the positioning unit is used to rotate and position the tunnel segment 1, the first telescopic member 9 drives the connected positioning plate 14 to move toward the tunnel segment 1. In order to reduce the number of first telescopic members 9 used, the positioning plate 14 moves while the rotating member 12 is driven to rotate under the action of the linkage rod 11 provided thereon. Then, the other positioning plate 14 can be pulled toward the tunnel segment 1 together under the action of another linkage rod 11 until the side of the tunnel segment 1 is completely in contact with the positioning plate 14. This completes the deflection positioning of the tunnel segment 1, ensuring that the two adjacent tunnel segments 1 always correspond to each other and achieves positioning.

[0064] The first telescopic member 9 and the second telescopic member 19 can be any one of an electric telescopic rod or a pneumatic telescopic rod, and the transmission member 8 can be any one of a hydraulic dual-axis motor and an electric dual-axis motor.

[0065] The traveling unit includes:

[0066] Slide track 3;

[0067] The two carrier frames 22 are respectively arranged at both ends of the carrier plate 5 and are provided with a power pulley block 4 , and the power pulley block 4 is mounted on the sliding track 3 .

[0068] In this embodiment, Figure 1 As shown, by arranging two supporting frames 22 at the two ends of the supporting plate 5, the supporting plate 5 is suspended on the base cushion layer 2, and by laying two sliding rails 3 on both sides of the base cushion layer 2, the power pulley group 4 is used as the moving medium to connect the supporting frame 22 with the sliding rail 3, thereby realizing automatic movement and stopping.

[0069] like Figures 1 to 7 As shown, a construction method for a prefabricated integrated pipe gallery under a large longitudinal slope is also provided, comprising the following steps:

[0070] Transporting each pipe gallery segment 1: using lifting equipment to lift each pipe gallery segment 1 in sequence to the base cushion layer 2 in the large longitudinal slope foundation pit;

[0071] Install the pipe gallery segment 1 at the lowest point of the large longitudinal slope: hoist the first pipe gallery segment 1 to the lowest point in the foundation pit on the large longitudinal slope, adjust it to the middle of the base cushion layer 2, and cast a pier at one end of the base cushion layer 2 to abut the first pipe gallery segment 1;

[0072] Move the adjacent tunnel segment 1: Use the walking unit to move the carrying plate 5 to the top of the adjacent tunnel segment 1, control the supporting unit to lift the tunnel segment 1, and use the walking unit again to move the supporting unit carrying the tunnel segment 1 to the side of the first tunnel segment 1;

[0073] Positioning the adjacent pipe gallery segment 1: Correcting the deviation of the pipe gallery segment 1 on the base layer 2 by controlling the movement of the positioning unit so that its axis is parallel to the axis of the first pipe gallery segment 1;

[0074] Docking two pipe gallery segments 1: Use a pushing member to push the pipe gallery segment 1 on the base cushion layer 2, so that the pipe gallery segment 1 approaches the first pipe gallery segment 1 and completes the positioning docking.

[0075] The implementation principle of the embodiment of the present application is as follows: the prefabricated pipe gallery segments 1 to be constructed are sequentially hoisted to the large longitudinal slope section by hoisting equipment, and the first pipe gallery segment 1 is placed at the lowest point of the large longitudinal slope section and adjusted to the middle of the base cushion layer 2, and the walking unit is started to carry the carrying plate 5 to the top of the adjacent pipe gallery segment 1. At this time, the supporting plate 17 is located at the bottom end of the fixing frame 21 (the third state, see Figure 7 ), and then by controlling the transmission member 8 in the lifting unit, it drives the two rotating rods 20 to rotate synchronously, thereby driving the lifting plate 17 to rise on the fixing frame 21, and the pipe gallery segment 1 can be lifted to separate it from the base layer 2 (the first state, see Figure 5 ), by starting the power pulley group 4, the pulley is driven by electricity to slide on the sliding track 3. When the pipeline gallery segment 1 in transportation is transported to the side of the pipeline gallery segment 1 that has been safely completed, the transmission member 8 is controlled to reverse, so that the lifting plate 17 moves downward on the fixed frame 21. When the pipeline gallery segment 1 in transportation is placed on the base cushion layer 2, the transmission member 8 continues to move until the upper surface of the lifting plate 17 has a certain distance from the base cushion layer 2 (the second state, see Figure 6 ), so that the lifting plate 17 is separated from the corridor segment 1; then the first telescopic member 9 is started to synchronously drive the two positioning plates 14 to move toward the corridor segment 1, correct its deviation, and achieve positioning; finally, the second telescopic member 19 is started to shrink its telescopic end and drive the pushing plate 15 to move in the lifting plate 17, thereby pushing the corridor segment 1 toward the installed corridor segment 1 until the docking is successful. After the docking is successful, the transmission member 8 is controlled again to make the lifting plate 17 located at the bottom end of the fixing frame 21 again to make way, and the operation is repeated to accurately install each corridor segment 1.

[0076] In summary, the present application can quickly position and dock two tunnel segments 1 without requiring excessive manual adjustment of the position and shape of the tunnel segments 1. This saves time, speeds up the construction process, and relatively improves the accuracy of docking.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
