Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a construction method of a cable structure system across obstacles. Background Art

[0002] In cable structure system construction projects, the cables are usually spread out and laid flat on the orthographic projection ground of the cable structure system setting area, and then the cables are lifted and tensioned using special equipment to complete the high-altitude installation of the cables. If environmental conditions are limited, a construction method that can overcome environmental obstacles should be developed.

[0003] like Figure 1 , Figure 2 as well as Figure 3 As shown, a cable structure system 2ˊ needs to be constructed between two end structures 1ˊ spaced apart. The cable structure system 2ˊ includes a plurality of cables 21ˊ and a secondary structure 22ˊ arranged on the cables 21ˊ. There is a protruding obstacle 3ˊ or a concave obstacle 3ˊ on the ground directly below the area where the cable structure system 2ˊ is set up. At this time, the cables 21ˊ cannot be laid out and unfolded on the ground. In order to overcome the limitations of the environment where the obstacle 3ˊ exists, in the existing construction method, a support structure is set up to cross the obstacle 3ˊ and provide a good working surface for the construction of the cables 21ˊ. That is, a support structure is first set up to cross the obstacle 3ˊ to obtain a working surface; then, the cables 21ˊ are unfolded and laid out on the working surface, and finally the lifting and tensioning operations of the cables 21ˊ are completed.

[0004] However, if the obstacle 3 is irregular or large in size, the support structure will tend to be complicated or large in size, resulting in a large amount of manpower and material resources being consumed in erecting the support structure, resulting in an increase in construction costs and risks.

[0005] Therefore, there is an urgent need for a construction method of a cross-obstacle cable structure system to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a construction method for a cable structure system across obstacles, which can avoid obstacles and complete the installation of the cable structure system without setting up complicated support structures in the obstacle area, thereby effectively reducing construction costs and construction risks.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0008] A method for constructing a cable structure system across obstacles is provided, comprising the following steps:

[0036] W5. The cable-supporting vehicles at both ends of the cable repeat steps W2 to W4 in the order from the middle of the span to the end of the span, and sequentially complete the installation of all the secondary structures on the two adjacent cables;

[0037] W6. On the remaining two adjacent cables, follow steps W1 to W5 to complete the installation of all remaining sub-structures.

[0039] As a preferred solution of the method for constructing a cross-obstacle cable structure system provided by the present invention, after the construction of the first cable is completed, a secondary structure is constructed on the cable and the adjacent cables every time a new cable is constructed; or, after the construction of all cables in the cable structure system is completed, a secondary structure is constructed on every two adjacent cables.

A lifting device is provided on the top of the upper cable work platform, and the lifting device is used to lift the secondary structure. Walking wheels are provided at the bottom of the upper cable work platform, and the walking wheels can engage with the cables and travel along the cables.

[0077] like Figure 4 As shown, this embodiment provides a construction method for a cable structure system across obstacles, comprising the following steps:

[0078] S1, selecting an area without an obstacle 2 or with the smallest obstacle 2 in the projection area of ​​the cable structure system 1 as a cable deployment area, and determining a construction order of multiple cables 11 in the cable structure system 1 according to the area of ​​the obstacle 2;

[0079] S2, spreading and paving the cables 11 to be constructed in the cable spreading area;

[0080] S3, lifting the cable 11 to a position not lower than a preset height;

[0081] S4, moving the cable 11 to the designated installation point according to the construction sequence;

[0082] S5, pulling the tension cable 11 into place, and connecting the two ends of the cable 11 to the end structures 3 on both sides respectively;

[0083] S6, repeating steps S2 to S5 according to the construction sequence until all cables 11 in the cable structure system 1 are installed;

[0084] The method for constructing a cross-obstacle cable structure system also includes the following steps: using the installed cables as equipment carriers, constructing a secondary structure in the cable structure system.

[0085] The obstacle-crossing cable structure system construction method provided in this embodiment can be applied to construction environments where there are large protruding obstacles or pit obstacles in the projection area of ​​the cable structure system 1. First, an area without obstacles or with the smallest obstacles is selected as the cable deployment area of ​​a single cable 11. The cable 11 is spread and flattened in the cable deployment area and then lifted to a preset height position, and then shifted to cross the obstacle until it reaches the designated installation point. Finally, the cable 11 is installed and tensioned in place. In addition, multiple cables 11 are installed in place in sequence according to the construction order. The installed cables 11 can be used to arrange operating equipment on them to provide a platform for the transportation and construction of personnel and materials on the cables 11, so as to realize the installation of the remaining substructures 12 or decorative structures of the cable structure system 1. This construction method can avoid the obstacle body 2 without setting up a cumbersome support structure in the obstacle body 2 area, and complete the installation of the cable structure system 1, effectively reducing construction costs and construction risks.

[0086] Preferably, step S2 further includes: installing a first traction rope 41 and a second traction rope 42 at both ends of the cable 11 ; the first traction rope 41 and the second traction rope 42 are used in subsequent operations of lifting the cable 11 , moving the cable 11 , and tensioning the cable 11 .

[0087] In step S3, the cable 11 is lifted by the first traction cable 41 and the second traction cable 42 or only by the first traction cable 41. After the cable 11 is lifted into place, the first traction cable 41 is inclined or vertical relative to the end structure 3, the second traction cable 42 is inclined relative to the end structure 3, and the second traction cable 42 is close to the designated installation point of the cable 11 relative to the first traction cable 41.

[0088] Specifically, if the cable 11 is lifted by the first traction cable 41 and the second traction cable 42, after being lifted to the right position, the first traction cable 41 and the second traction cable 42 are both inclined relative to the end structure 3; if the cable 11 is lifted only by the first traction cable 41 and the second traction cable 42 follows, the first traction cable 41 is perpendicular to the end structure 3, and the second traction cable 42 is inclined relative to the end structure, that is, Figure 5 After the state shown, the cable 11 can be displaced, that is, step S4.

[0089] Specifically, step S4 includes:

[0090] S41, the first traction rope 41 is gradually extended, and the second traction rope 42 is gradually shortened, so that the cable 11 completes a single displacement toward its designated installation point.

[0091] That is, the cable 11 is Figure 5 The position in the Figure 6 The position in Figure 5In the embodiment, the first traction rope 41 is perpendicular to the end structure 3, and the second traction rope 42 is inclined relative to the end structure 3. When the first traction rope 41 is extended and the second traction rope 42 is shortened, the cable 11 can be displaced toward the designated installation point. Figure 6 As shown, at this time, the first traction rope 41 is inclined relative to the end structure 3, and the second traction rope 42 is perpendicular to the end structure 3. It should be noted that the first traction rope 41 and the second traction rope 42 at both ends of the cable 11 extend and shorten synchronously.

[0092] S42, the first traction rope 41 is shifted to the next anchor point, so that the first traction rope 41 is inclined relative to the end structure 3, and the first traction rope 41 is close to the designated installation point of the cable 11 relative to the second traction rope 42, such as Figure 7 Status shown.

[0093] S43, the second traction rope 42 is gradually extended, and the first traction rope 41 is gradually shortened, so that the cable 11 is shifted again toward its designated installation point.

[0094] That is, the cable 11 is Figure 7 The position in the Figure 8 The position in Figure 7 In the embodiment, the second traction rope 42 is perpendicular to the end structure 3, and the first traction rope 41 is inclined relative to the end structure 3. When the second traction rope 42 is extended and the first traction rope 41 is shortened, the cable 11 can be displaced toward the designated installation point. Figure 8 As shown, at this time, the first traction rope 41 is perpendicular to the end structure 3 , and the second traction rope 42 is inclined relative to the end structure 3 .

[0095] S44 , the second traction rope 42 is shifted to the next anchor point, so that the second traction rope 42 is inclined relative to the end structure 3 , and the second traction rope 42 is close to the designated installation point of the cable 11 relative to the first traction rope 41 .

[0096] At this time, the states of the first traction rope 41 and the second traction rope 42 are similar to those in step S41. Subsequently, the first traction rope 41 is extended and the second traction rope 42 is shortened, so that the cable 11 can be moved again.

[0097] S45, repeat steps S41 to S44 until the cable 11 is moved to its designated installation point. Fig. 9 As shown, after multiple shifts, the first cable 11 is moved to the side span position, and the remaining cables 11 are installed in sequence from the side span position according to the construction order.

[0098] More specifically, the first traction rope 41 is connected to a first power device, and the second traction rope 42 is connected to a second power device. In step S3, the first power device lifts the cable 11 to a preset height position through the first traction rope 41 or the second power device lifts the cable 11 through the second traction rope 42. Moreover, the extension and shortening of the first traction rope 41 and the second traction rope 42 are also completed by the two power devices respectively. Exemplarily, the first power device and the second power device can be devices such as a winch or an electric hoist, which can smoothly lift the cable 11, and can also achieve the extension and shortening of the first traction rope 41 and the second traction rope 42, and achieve the displacement of the cable 11. Preferably, the first traction rope 41 and the second traction rope 42 are controlled by a computer program to ensure that the traction ropes at both ends of the cable 11 are extended and shortened synchronously, and the moving speed of the two ends of the cable 11 is made as consistent as possible.

[0099] In step S42 and step S44, the first power device and the second power device are shifted to the next anchor point by a sliding device or a lifting device. For example, the sliding device includes a slideway provided on the end structure 3, and the first power device and the second power device correspond to a slideway respectively. The two can move along the corresponding slideways and can be fixed at the designated position by the anchor assembly. Of course, the first power device and the second power device can also be transported to the designated position by a lifting device (crane).

[0100] See also Fig.10 and Fig.11 , step S5 comprises:

[0101] S51, pull the first traction rope 41 or the second traction rope 42 at one end of the cable 11 to the right position, and complete the installation of the cable head pin shaft; Fig.10 As shown, the right end of the cable 11 is pulled into place by the first traction cable 41 or the second traction cable 42 , and the pin is installed with the ear plate on the end structure 3 .

[0102] S52, pulling the first traction rope 41 or the second traction rope 42 at the other end of the cable 11 to pull the cable 11 into place and complete the installation of the cable head pin. Fig.11 As shown, the left end of the cable 11 is pulled into place by the first traction cable 41 or the second traction cable 42 , and the pin is installed with the cable head or the ear plate on the end structure 3 .

[0103] The cable 11 should have sufficient tension. In step S52, if the tension of the cable 11 is less than the set threshold, the cable 11 is directly tensioned into place by the first power device or the second power device. That is, the tension of the cable 11 is small, and the first power device pulling the first traction cable 41 or the second power device pulling the second traction cable 42 is sufficient to tension the cable 11 into place, meeting the tension requirement.

[0104] If the tensioning force of the cable 11 is greater than or equal to the set threshold, the cable 11 is first pulled by the first power device or the second power device, and then replaced with a special tensioning device to complete the tensioning of the last section of the cable 11. That is, in this case, the tensioning force of the cable 11 is relatively large, and the first power device and the second power device are not enough to complete the tensioning operation of the cable 11. Therefore, firstly, the first traction cable 41 is pulled by the first power device or the second traction cable 42 is pulled by the second power device to make the left end of the cable 11 approach the ear plate on the end structure 3, and then replaced with a special tensioning device for the cable 11, which can provide a sufficiently large tensioning force to finally tension the cable 11 in place, ensure that the cable shape and cable force of the cable 11 meet the requirements, and after tensioning in place, the cable head at the end of the cable 11 is connected to the ear plate on the end structure 3 through a pin shaft.

[0105] In this embodiment, after step S5 (after a single cable 11 is installed in place), the first traction cable 41 , the second traction cable 42 and the matching first power equipment and second power equipment on the cable 11 are removed for the construction of the remaining cables 11 .

[0106] In step S3, the preset height reached by the cable 11 should satisfy: when performing step S4, the lowest point of the cable 11 is not lower than the height of the obstacle 2, so as to ensure that during the subsequent movement of the cable 11, the cable 11 will not interfere with the obstacle 2, thereby preventing the obstacle 2 from blocking the displacement of the cable 11.

[0107] like Figures 12 to 18 , which is a schematic diagram of the construction of the secondary structure 12.

[0108] Specifically, using the installed cable 11 as the equipment carrier, the steps of constructing the secondary structure 12 in the cable structure system 1 include:

[0109] W1. Install the cable-supporting operation vehicle 5 at a position close to the end structure 3 on two adjacent cables 11 that have been installed in place.

[0110] like Fig.12 As shown, the cable-supporting vehicle 5 is installed at a position of the cable 11 close to the left end structure 3 .

[0111] In step W1 , optionally, the cable-supporting vehicle 5 may be installed above the cable 11 by a small crane.

[0112] W2. Load the secondary structure 12 onto the cable-supporting operation vehicle 5.

[0113] Optionally, the installation of the cable-supporting vehicle 5 and the loading of the secondary structure 12 onto the cable-supporting vehicle 5 are completed by a lifting device arranged on the ground or a lifting device arranged on the end structure 3 .

[0114] Specifically, if site conditions and installation height permit, lifting equipment (such as a small crane) can stand on the ground to complete the lifting of the cable-supported work vehicle 5 and the subsequent secondary structure 12; if site conditions and installation height are limited, lifting equipment (such as a mobile small crane) can be arranged on the top of the end structure 3 to complete the lifting of the cable-supported work vehicle 5 and the subsequent secondary structure 12. The choice can be made according to the specific construction environment.

[0115] Specifically, the cable-supporting operation vehicle 5 stops near the end structure 3 , and the secondary structure 12 is hoisted onto the cable-supporting operation vehicle 5 by the small crane described in step W1 .

[0116] W3, the cable-supporting operation vehicle 5 moves from a position close to the end structure 3 to the mid-span and installs the secondary structure 12.

[0117] See also Fig.13 , the cable-supporting operation vehicle 5 moves from the left side to the mid-span position, transports the secondary structure 12 to the mid-span position, and then the operator installs the secondary structure 12 in place. At the same time, the cable-supporting operation vehicle 5 on the right side is installed in place.

[0118] W4. The cable-supporting operation vehicle 5 returns to a position close to the end structure 3.

[0119] See also Fig.14 The cable-supported working vehicle 5 on the left side returns empty to a position close to the end structure 3, while the cable-supported working vehicle 5 on the right side loads the secondary structure 12 and moves from the right side to the mid-span position. After arriving at the designated position, the operating personnel install the secondary structure 12 in place.

[0120] W5, the cable-supporting vehicles 5 at both ends of the cables 11 repeat steps W2 to W4 in the order from the middle of the span to the end of the span, and complete the installation of all the secondary structures 12 on the two adjacent cables 11 in sequence.

[0121] like Fig.15 As shown, the secondary structure 12 on the two adjacent cables 11 at the side span position is installed.

[0122] W6. On the other two adjacent cables 11, follow steps W1 to W5 to complete the installation of all other secondary structures 12.

[0123] After the installation of the secondary structure 12 on a group of adjacent cables 11 is completed, the cable-carrying vehicle 5 is hoisted onto the remaining adjacent cables 11 , and steps W1 to W5 are repeated until the installation of all the secondary structures 12 is completed.

[0124] In an optional embodiment, after the construction of the first cable 11 is completed, each time a new cable 11 is completed, a secondary structure 12 is constructed on the cable 11 and the adjacent cable 11. Figure 12 to Figure 14As shown, the construction of the two cables 11 at the side span position is completed, and the secondary structure 12 is installed on the two cables 11 according to the above-mentioned secondary structure 12 construction steps. After the installation is completed, the third cable 11 is constructed. After the construction of the third cable 11 is completed, as shown in FIG. Fig.15 , Fig.16 as well as Fig.17 As shown, the cable-supporting vehicle 5 is hoisted onto the third cable 11 and the second cable 11, and the secondary structure 12 between the third cable 11 and the second cable 11 is constructed. This is repeated until all the secondary structures 12 are constructed. Fig.18 shown.

[0125] In another new embodiment, after all cables 11 in the cable structure system 1 are constructed, a secondary structure 12 is constructed on every two adjacent cables 11. For example, the secondary structure 12 on the two cables 11 at the far side span position is constructed first, and the secondary structures 12 on the remaining adjacent cables 11 are constructed in sequence from the far side span position to the near side span position until the installation is completed.

[0126] The axonometric diagram after the construction of all the cables 11 and the secondary structure 12 in the cable structure system 1 is completed is as follows: Fig.19 shown.

[0127] In this embodiment, Fig. 20 and Fig.21 As shown, the cable-supported work vehicle 5 includes an upper cable work platform 51 and a lower cable work platform 52. A lifting device 53 is provided on the top of the upper cable work platform 51. The lifting device 53 is used to lift the secondary structure 12. A running wheel 54 is provided on the bottom of the upper cable work platform 51. The running wheel 54 can engage with the cable 11 and move along the cable 11. The upper cable work platform 51 and the lower cable work platform 52 provide a working surface for lifting and installing the secondary structure 12. The engagement of the running wheel 54 with the cable 11 can ensure the stability of the cable-supported work vehicle 5 on the cable 11.

[0128] Optionally, the lifting device 53 on the cable-supporting vehicle 5 includes a crane 531, such as Fig. 20 As shown, a rope of the crane 531 is connected to a first hook 532 , and the first hook 532 is used to lift the secondary structure 12 .

[0129] Optionally, the lifting device 53 on the cable-supporting vehicle 5 includes a crane device 533, such as Fig.21 As shown, the crane equipment 533 is installed on the cable working platform 51 through the rotating platform 535, and the rope of the crane equipment 533 is connected with the second hook 534, so as to realize the integrated lifting, transportation and installation. Furthermore, the counterweight 536 on the crane equipment 533 can be adjusted and shifted intelligently according to the center of gravity offset and the inclination angle of the cable-supported working vehicle 5, so as to improve the stability of the cable-supported working vehicle 5 and ensure the anti-overturning ability of the cable-supported working vehicle 5.

[0130] For example, the cable-supported vehicle 5 can have its own driving power, or can rely on a traction device and a traction rope to apply driving power. For example, the cable-supported vehicle 5 travels on the cable 11 through a winch and a wire rope.

[0131] In the construction method of the cross-obstacle cable structure system provided in this embodiment, on the basis of the completion of the installation of the cable 11, a technical solution is proposed to use the cable 11 to set up the cable-bearing work vehicle 5 to complete the installation of the secondary structure 12, which effectively avoids the influence of the obstacle body 2 on the lifting of the secondary structure 12. In addition, it also provides an operating platform for high-altitude workers, ensures the safety of high-altitude operations, and provides a guarantee for the improvement of installation quality.
