Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more specifically, to an overhead pipeline and a pipe gallery installation method. Background Art

[0002] At present, in the construction process of external network overhead pipelines and supporting corridors of industrial and municipal facilities such as metallurgy, chemical industry, electric power, and industrial parks, the external network construction front is long and the external network area is large. The general construction sequence is: first civil foundation, then pipeline portal bracket and steel corridor truss installation, and then water flow is interspersed to carry out ground assembly of various medium pipelines, aerial hoisting, positioning in the truss corridor, and fixing and welding after positioning. Under normal circumstances, cranes need to cooperate in the entire construction cycle, which brings greater pressure on mechanical shifts to the project, resulting in high construction costs and long cycles.

[0003] In addition, in special circumstances such as when the owner is eager to start production or shorten the construction period, or when there are many medium pipelines laid in the corridor, it is difficult to complete the task according to the traditional construction sequence process. Or, after a partial corridor is in place, it is limited by the lifting position or area and the internal pipelines cannot be lifted smoothly. It is also necessary to reserve the structural beams on one side of the corridor in advance, and restore the original design structure after the pipeline is successfully lifted in, which brings safety and economic burdens to the on-site construction. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to provide an overhead pipeline and pipe gallery installation method to solve the problems of high frequency of using cranes in existing pipeline construction and difficulty in pipeline lifting, resulting in high cost and long cycle.

[0006] The pipeline to be suspended is passed through the interior of the pipe gallery by means of a pre-installed pulley, and the pipeline and the pipe gallery are fixed;

[0007] The pipe gallery with the pipeline fixed thereon is hoisted as a whole onto the portal frame.

[0008] In addition, an optional technical solution is that the pipeline corridor is transported to the designated location on site, including:

[0009] The pipe gallery is manufactured at the construction site and transferred to the designated location; or, the pipe gallery manufactured in the external structure factory is transported to the designated location.

[0010] In addition, an optional technical solution is to insert the pipeline to be suspended into the interior of the pipe gallery by means of a pre-installed pulley, and to fix the pipeline and the pipe gallery, including:

[0011] Lifting one end of the pipe onto a pulley and lifting the other end of the pipe onto another pulley;

[0012] The pipeline is pulled into the pipe gallery by the pulley, and the pipeline is slid to a preset position through a slideway preset in the pipe gallery;

[0013] The pipes at preset positions are fixed in the pipe gallery by means of U-shaped pipe clamps.

[0014] In addition, an optional technical solution is that the slideway includes an I-beam track laid at the bottom of the pipe gallery and a roller bar arranged on the I-beam track; wherein,

[0015] The roller is used to roll on the I-beam track to assist the pipeline in moving in the pipeline gallery.

[0016] In addition, an optional technical solution is that after the pipeline slides to a preset position, it also includes:

[0017] The pipeline is pulled up by the fall chains symmetrically arranged on the top crossbeam of the pipe gallery, and the I-beam rail and the roller are moved out;

[0018] The pipeline is lowered to the preset position.

[0019] In addition, an optional technical solution is to fix the pipeline in the pipe gallery by a U-shaped pipe clamp, including:

[0020] Arranging an isolation plate on the bottom crossbeam of the pipe gallery;

[0021] The pipeline is placed on the isolation plate and is locked and positioned by the U-shaped pipe clamp.

[0022] In addition, an optional technical solution is that the pulley vehicle includes a body beam, a first pulley block arranged at one end of the body beam, a second pulley block arranged at the other end of the body beam, and a limit assembly arranged on the body beam; wherein,

[0023] The pipeline is placed on the cross beam of the vehicle body and is limited in position by the limiting assembly;

[0024] The first pulley set and the second pulley set cooperate to assist the sliding of the pipeline.

[0025] In addition, an optional technical solution is that a central opening is provided on the vehicle body cross beam;

[0026] The limit assembly includes a left adjustment lever and a right adjustment lever arranged in the central opening;

[0027] The positions of the left adjustment lever and the right adjustment lever in the central opening are adjustable, and the pipeline is limited between the left adjustment lever and the right adjustment lever.

[0028] In addition, an optional technical solution is that the first pulley block includes a vertical screw rod passing through the vehicle body cross beam, an adjusting nut arranged at the upper end of the vertical screw rod, a round steel shaft arranged at the lower end of the vertical screw rod, and steel wheels located on both sides of the round steel shaft; and,

[0048] In order to describe the overhead pipeline and pipe gallery installation method of the present invention in detail, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0049] Figure 1 The schematic flow chart of the overhead pipeline and pipe gallery installation method according to an embodiment of the present invention is shown; Figures 2 to 7 The schematic principle and partial schematic structure of the overhead pipeline and pipe gallery installation method according to an embodiment of the present invention are shown from different angles.

[0050] like Figures 1 to 7 As shown together, the overhead pipeline and pipe gallery installation method of the embodiment of the present invention at least includes the following steps:

[0051] S100: Construction of civil support foundation piers, and installation of portal frames on the completed support foundation piers; at the same time, transport the pipeline corridor to the designated location on site.

[0052] Among them, when constructing the overhead pipeline, firstly, the civil support foundation pier 1 is constructed at the designated location, the travel support foundation pier 1 is installed, and then the portal frame 2 is installed thereon to lay a good foundation for the installation of the pipe gallery 3 and the pipeline 6. In this step, the production and transportation of the pipe gallery 3 can also be carried out simultaneously. As an example, the pipe gallery 3 can be produced on-site at the construction site, which can avoid the long-distance transfer operation, and the steel structure pipe gallery 3 produced by the external structure manufacturer can also be transported to the designated location of the construction site at a low cost.

[0053] S200: The pipeline to be suspended is passed into the pipe gallery through a pre-installed pulley, and the pipeline and the pipe gallery are fixed.

[0054] Among them, this step further includes: lifting one end of the pipe 6 onto a pulley 72, lifting the other end of the pipe 6 onto another pulley 71, and then pulling the pipe 6 into the corridor 3 under the action of the pulley (including the pulley 71 and the pulley 72), and sliding the pipe 6 to a preset position through a slide preset in the corridor 3, and finally fixing the pipe 6 at the preset position in the corridor 3 through the U-shaped pipe clamp 4.

[0055] Specifically, the slideway may include an I-beam rail 9 laid at the bottom of the pipe gallery 3 and a roller 8 arranged on the I-beam rail 9, and the roller 8 can roll on the I-beam rail 9 to assist the pipeline 6 in moving in the pipe gallery 3. After the pipeline 6 slides to the preset position, the pipeline is pulled up by the fall chain 10 symmetrically arranged on the top crossbeam of the pipe gallery 3, the I-beam rail 9 and the roller 8 are moved out, and then the pipeline 6 is lowered to the preset position.

[0056] In a specific embodiment of the present invention, in order to prevent hard contact between the pipe 6 and the pipe gallery 3 and prevent the pipe 6 from sliding and damaging the parent material, an isolation plate 5 can be set on the bottom crossbeam of the pipe gallery 3, and then the pipe 6 is placed on the isolation plate 5, and finally locked and positioned by a U-shaped pipe clamp 4.

[0057] As a specific example, in the overhead pipeline and pipe gallery installation method of the embodiment of the present invention, the pipeline 6 is first inserted into the pipe gallery 3 on the ground, and the U-shaped pipe clamp 4 is used in conjunction with polytetrafluoroethylene (i.e., isolation plate) to fix the pipe 6 to the bottom of the pipe gallery 3; and for some medium and large diameter steel pipes, such as pipes 6 with a diameter of more than 273 mm, since the entire pipeline is relatively heavy, a roller skate-type pulley can be used to transport the pipeline.

[0058] Specifically: first, one end of the pipe 6 is lifted and pushed into the pulley by manually using tools such as a crowbar, so that one end of the pipe 6 is mounted on the pulley; similarly, the pulley is repeatedly set at the other end of the pipe 6. Since the pulley adopts a flat single-axis, it will automatically level after being stressed, so that the pipe 6 itself can be used as a load-bearing body frame, and the pipe 6 is pulled into the pipe gallery 3 by manpower or a winch such as a fall chain 10. After one end of the pipe 6 enters the pipe gallery 3, the pipe 6 can be slid into the pipe gallery 3 through the I-beam track pre-laid at the bottom of the pipe gallery 3 in cooperation with the roller 8; after the pipe 6 moves to the preset position, the pipe 6 is evenly pulled up by the fall chain 10 symmetrically arranged on the crossbeam at the top of the pipe gallery 3, and then the guide rail, roller 8 and other components are withdrawn, and finally the pipe 6 is put on the ground and returned to its position, and the pipe 6 is fixed by the U-shaped pipe clamp 4. A polytetrafluoroethylene plate is used between the bottom of the pipe 6 and the crossbeam to ensure that the position of the pipe 6 is fixed and to avoid sliding and damaging the parent material.

[0059] S300: Lift the pipe gallery with fixed pipes onto the portal frame as a whole.

[0060] In a specific embodiment of the present invention, the pulley vehicle may further include a body beam 16, a first pulley group arranged at one end of the body beam 16, a second pulley group arranged at the other end of the body beam 16, and a limiting component arranged on the body beam 16; wherein the pipe 6 is placed on the body beam 16 and is limited by the limiting component, and the first pulley group and the second pulley group cooperate to assist the pipe 6 in sliding, similar to a roller skate structure.

[0061] In order to enable the pulley to meet the transportation requirements of pipes 6 of different sizes, a central opening 17 can be provided on the body cross beam 16, and the position limiting assembly includes a left adjustment lever 11 and a right adjustment lever 12 provided in the central opening 17, and the positions of the left adjustment lever 11 and the right adjustment lever 12 in the central opening 17 are adjustable. After the pipe 6 is placed on the body cross beam 16, the position of the pipe 6 can be locked by adjusting the left adjustment lever 11 and the right adjustment lever 12. In addition, a downwardly concave groove can also be provided in the middle of the body cross beam 16 to provide a preliminary positioning of the pipe 6.

[0062] In addition, in order to ensure the firmness between the left adjustment lever 11 and the right adjustment lever 12 and the vehicle body cross beam 16, a sleeve 13 can be set at the bottom of the two to enhance the rigidity. The sleeve 13 is fixed to the vehicle body cross beam 16 by a locking bolt to ensure the fitting support area with the vehicle body cross beam 16. At the same time, a double screw can be used for locking to meet the fixing requirements of pipes 6 at different heights.

[0063] Further, the first pulley block may include a vertical screw rod passing through the body cross beam 16, an adjusting nut 14 arranged at the upper end of the vertical screw rod, a double-headed screw rod 18 arranged at the lower end of the vertical screw rod, and a round steel shaft located on the double-headed screw rod 18, and steel wheels 15 located on both sides of the round steel shaft, wherein the height of the vertical screw rod is adjustable and then locked by adjusting the nut 14, and the width of the double-headed screw rod 18 is adjustable and locked by the corresponding nut. This structure can adjust the height and width of the pulley vehicle, thereby meeting the pipeline 6 transportation requirements of different construction scenes. It can be seen that the structure of the second pulley block is the same as that of the first pulley block, and will not be repeated here.

[0064] According to the above-mentioned method for installing overhead pipelines and pipe gallery of the present invention, before the pipe gallery is hoisted, the pipeline can be inserted into the interior of the pipe gallery and fixed in advance by means of a pre-installed pulley vehicle, and then the pipe gallery provided with the pipeline can be hoisted onto a portal frame as a whole, which can reduce the high-altitude hoisting operation of the crane on the pipeline and realize the one-time hoisting of the pipe gallery and the pipeline, thereby reducing the frequency of use of the crane, while ensuring construction safety and efficiency, and reducing construction costs; in addition, the height, span and other dimensions can be adaptively adjusted according to different pipeline entities, so that it will not occupy too much space and has stronger maneuverability, and can be suitable for overhead operations of pipelines of multiple heights and sizes.

[0065] As described above, the method for installing an overhead pipeline and a pipe gallery according to the present invention is described by way of example with reference to the accompanying drawings. However, it should be understood by those skilled in the art that various improvements can be made to the method for installing an overhead pipeline and a pipe gallery proposed by the present invention without departing from the content of the present invention. Therefore, the protection scope of the present invention should be determined by the content of the attached claims.
