Detailed implementation mode

[0032] As Figures 1 - 6 shown in the figure, a construction channel operation device convenient for vibration includes a steel bar frame 3 arranged on the outer side of the tower base 1 along the circumferential direction. A plurality of vibration channels 2 are detachably arranged inside the steel bar frame 3. The upper side of the vibration channel 2 is inclined towards the center side of the tower base 1. The vibration channel 2 is used for vibrating the concrete by the vibrating rod 6 at the designed position and angle.

[0033] During the construction of a certain bridge, the main span is a double-tower small side-box combined hybrid beam cable-stayed bridge with a main span of 555 meters. The main tower is a cable tower with an A-shaped tower shape. The main tower foundation adopts a separated caisson with a group pile foundation. The caisson is 5.5 m high, and there is a 2 m high tower base on it. The tower base is made of C40 concrete and is an octagonal frustum. The bottom plane is 19.5 m long and 19.5 m wide, and the top plane is 14.5 m long and 11.5 m wide. Due to the large inclined surface of the tower base, it is necessary to ensure the vibration quality while having a certain construction efficiency. By arranging a plurality of inclined vibration channels 2 inside the steel bar frame 3, the vibration effect of the vibrating rod 6 can be facilitated, and at the same time, the movement operation is convenient. The vibrating rod 6 is extended into the bottom of the tower base 1 through the vibration channel 2 to vibrate the concrete in the inclined surface part densely, and at the same time, the bubbles in the inclined surface are brought out. The overall construction quality is higher, and the bearing capacity of the tower base 1 is stronger.

[0034] As Figures 7 - 10 shown in the figure, in a preferred solution, the vibration channel 2 includes a spiral reinforcement 201. Fixed reinforcements 202 are arranged in parallel inside the spiral reinforcement 201. The vibrating rod 6 is inserted into the spiral reinforcement 201. The steel bar frame 3 and the concrete are connected to form a first inclined plane 101 and a second inclined plane 102 on the tower base 1.

[0035] During the project construction process, the spiral reinforcement 201 and the fixed reinforcement 202 are made of φ20 round steel, so as to ensure that the force-bearing body has a certain strength and stiffness to meet the use requirements. Through the above settings, it is convenient for the vibrating rod 6 to vibrate the inclined angle sufficiently. At the same time, an observation hole is arranged at the lower part of the corresponding inclined formwork, which is convenient for checking whether the position of the vibrating rod 6 during operation is accurate.

[0036] In a preferred embodiment, the steel bar frame 3 includes a plurality of main bars 301 and vertical bars 302 arranged alternately. The main bars 301 and the vertical bars 302 are connected to form a net structure, and the steel bar frame 3 is connected to the vibrating channel 2 through the fixing assembly 4.

[0037] According to the requirement of the inclination angle, a suitable steel bar frame 3 is fabricated. At the same time, during installation, the fixing assembly 4 is used for assembly. Since there are certain errors in the fabrication process, the problem of deformation between the vibrating channel 2 and the steel bar frame 3 can be eliminated. For the vibrating channel 2 and the steel bar frame 3 with relatively small deformation, spot welding can be used for fixation.

[0038] In a preferred embodiment, the fixing assembly 4 includes a sleeve 401 and a hook 402. The sleeve 401 is sleeved on the fixing bar 202, the hook 402 is hung on the main bar 301, and the sleeve 401 and the hook 402 are connected by a bidirectional threaded rod 404.

[0039] When fabricating the vibrating channel 2, a suitable number of sleeves 401 are provided on the upper and lower sides of some vibrating channels 2. After the hook 402 is installed on the steel bar frame 3, the angles of the sleeve and the hook can be adjusted to quickly complete the fixation, which is convenient to operate and has a good use effect.

[0040] In a preferred embodiment, a locking platform 403 is provided on one side of the hook 402. First threaded holes 405 and second threaded holes 406 are respectively provided on the sleeve 401 and the locking platform 403, and the bidirectional threaded rod 404 is threadedly connected to the first threaded hole 405 and the second threaded hole 406 respectively.

[0041] The fixing effect is good by pulling with the bidirectional threaded rod 404, and the overall locking is sufficient. Multiple fixing assemblies 4 cooperate and restrain each other, ensuring the stability of the connection between the vibrating channel 2 and the steel bar frame 3, and the installation and adjustment are convenient.

[0042] In a preferred embodiment, the fixing bar 202 and the spiral bar 201 are connected by a protrusion 203, and a hexagonal platform 407 is further provided on the outer side of the bidirectional threaded rod 404.

[0043] The protrusion 203 ensures a larger welding surface between the spiral bar 201 and the fixing bar 202, and at the same time better ensures the restraint of the movement range of the sleeve 401.

[0044] Such as Figures 11 - 15 In a preferred embodiment, a propulsion assembly 5 is slidably provided inside the vibrating channel 2. The propulsion assembly 5 includes two opposite support plates 501. A second limiting clip 507 and a top plate 508 are provided at the lower part of the support plate 501. The second limiting clip 507 and the top plate 508 are connected to form a clamping space for the vibrating rod 6.

[0045] During use, by installing the propulsion assembly 5 in the vibration channel 2, it can ensure that the vibration rod 6 enters the vibration channel 2 and is inserted into the concrete more precisely, avoiding the problem of collision with the spiral reinforcement 201 or the fixed reinforcement 202, and facilitating the removal of the vibration rod 6 after vibration is completed.

[0046] In a preferred solution, the vibration rod 6 includes a cable 601 and a vibration head 602. The vibration head 602 and the cable 601 are respectively detachably arranged inside the second limit clip 507 and the top plate 508. A spring 504 is abutted between the two support plates 501. A guide rod 7 is provided on one side of the spring 504. The guide rod 7 passes through the support plate 501, and the distance of the gap 510 is adjusted by the length of the spring 504.

[0047] By applying force to the support plate 501 and pressing the support plate 501, the distance between the two support plates 501 is adjusted, that is, the distance between the two second limit clips 507 is changed, facilitating the quick removal of the propulsion assembly 5.

[0048] In a preferred solution, the second limit clip 507 is connected to the first limit clip 506 through a connecting plate 509 and an arc plate 505, and the first limit clip 506 is slidably connected to the fixed reinforcement 202.

[0049] The first limit clip 506 is restricted by the fixed reinforcement 202, and the overall movement is convenient and the movement accuracy is high.

[0050] In a preferred solution, through holes 502 are provided through the support plate 501. The guide rod 7 is located inside the through hole 502. The guide rod 7 is connected to the support plate 501 through a nut 8. The spring 504 abuts inside the fixed cylinder 503. The fixed cylinder 503 is arranged inside the support plate 501. A step 511 and a third threaded hole 512 are provided inside the support plate 501. The spring 504 abuts on the step 511, and a screw 9 is connected to the third threaded hole 512.

[0051] The overall production is simple, the installation is convenient, and the use state is stable. The two support plates 501 only move in the central axis direction of the spring 504, with high accuracy for repeated use and easy operation.

The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims.
