Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, and in particular to a concrete guiding device for a reverse slope tower base. Background Technology

[0002] With the continuous development of bridge construction, in addition to meeting the requirements of load-bearing capacity, more and more complex shapes of structures have emerged in order to meet the requirements of aesthetic design. For example, the outer side of the structure has a beveled surface, and counter-pressure formwork needs to be set during construction. This is mainly reflected in structures such as tower bases, tower columns, cable saddle supports and anchor chambers. This type of structure presents a narrow-mouth shape with a wide bottom and a narrow top.

[0003] For the current 45° sloped tower base, traditional pump pipes cannot reach the bottom of the slope. Workers can only push the pump pipe to allow the concrete to flow as much as possible into the bottom of the slope. Since the structure is mostly large volume concrete, the concrete pouring work is long and the working area is large. Not only is the workload of the workers heavy, but the pouring effect is also difficult to guarantee. Therefore, how to deliver concrete to the sloped tower base more easily and conveniently has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a concrete guiding device for a reverse slope tower base, which not only effectively reduces the construction difficulty but also greatly improves the construction quality. The technical solution of this patent is simple to construct and can be reused repeatedly, making it of great promotional value.

[0005] This utility model is achieved through the following technical solution:

[0006] A concrete guiding device for a reverse slope tower base includes a directional adjustment mechanism, a guide pipe fixing mechanism, and a straight guide pipe. The directional adjustment mechanism is detachably and fixedly connected to the rigid frame of the reverse slope tower base, which is a supporting structure for the steel reinforcement skeleton of the reverse slope tower base. One end of the guide pipe fixing mechanism is adjustablely plugged into the directional adjustment mechanism, and the other end of the guide pipe fixing mechanism clamps and locks the straight guide pipe. The lower end of the straight guide pipe is inserted into the lower region of the reverse slope tower base, and the end of the pump pipe for conveying concrete is inserted into the upper part of the straight guide pipe. The precast concrete for pouring the reverse slope tower base is guided along the straight guide pipe to the lower region of the reverse slope tower base.

[0007] As can be seen, in the above technical solution, before using this patented technical solution, the rigid frame and template of the reverse slope tower base have been constructed. First, the directional adjustment mechanism is fixedly connected to the rigid frame of the reverse slope tower base, and then the straight guide pipe is fixedly connected to the guide pipe fixing mechanism.

The precast concrete for pouring the reverse slope tower base is guided along the straight guide pipe to the lower area of ​​the reverse slope tower base, thereby realizing the easy and convenient delivery of concrete to the reverse slope tower base. This not only effectively reduces the construction difficulty but also greatly improves the construction quality. This patented technical solution is simple to construct and can be reused repeatedly, making it highly valuable for promotion.

[0008] According to the above technical solution, preferably, the directional adjustment mechanism includes a fixed base and an insert plate.

[0012] According to the above technical solution, preferably, the clamp assembly includes an annular clamp with an open structure and a quick-release unit. The annular clamp is fixedly connected to the end of the support plate, and the quick-release unit is used to lock the annular clamp.

[0029] As shown in the figure, this embodiment provides a concrete guiding device for a reverse slope tower base, including a directional adjustment mechanism 1, a guide pipe fixing mechanism 2, and a straight guide pipe 3. The directional adjustment mechanism 1 is detachably and fixedly connected to the rigid frame 4 of the reverse slope tower base, and the rigid frame 4 is the supporting structure of the steel reinforcement frame of the reverse slope tower base. One end of the guide pipe fixing mechanism 2 is adjustablely plugged into the directional adjustment mechanism 1, and the other end of the guide pipe fixing mechanism 2 clamps and locks the straight guide pipe 3. The lower end of the straight guide pipe 3 is inserted into the lower region of the reverse slope tower base, and the end of the pump pipe for conveying concrete is inserted into the upper part of the straight guide pipe 3. The precast concrete for pouring the reverse slope tower base is guided along the straight guide pipe 3 to the lower region of the reverse slope tower base. Furthermore, the directional adjustment mechanism 1 includes a fixed base 5 and an insert plate 6. The fixed base 5 is detachably fixed to the rigid frame 4 of the reverse slope tower base by locking bolts. Both the fixed base 5 and the reverse slope tower base rigid frame 4 have round holes 7 that are compatible with the locking bolts. The insert plate 6 is vertically fixed to the fixed base 5. The operator places the directional adjustment mechanism 1 on the reverse slope tower base rigid frame 4, aligning the round holes 7 on the fixed base 5 and the reverse slope tower base rigid frame 4, and uses the locking bolts to fix the directional adjustment mechanism 1 on the reverse slope tower base rigid frame 4. The conduit fixing mechanism 2 includes a support plate 8 and a clamp assembly. One end of the support plate 8 has a slot 13 that is compatible with the insert plate 6.

The assembly is simple and convenient.

[0030] Before using this patented technology, the rigid frame 4 and formwork of the reverse slope tower base have been constructed. The next step is to pour concrete. The workers first fix the directional adjustment mechanism 1 to the rigid frame 4 of the reverse slope tower base, and then fix the straight guide pipe 3 to the guide pipe fixing mechanism 2. The end of the guide pipe fixing mechanism 2 is then inserted into the directional adjustment mechanism 1 to lock the guide pipe fixing mechanism 2 and the directional adjustment mechanism 1. The end of the pump pipe for conveying concrete is inserted into the upper part of the straight guide pipe 3. The precast concrete for pouring the reverse slope tower base is guided along the straight guide pipe 3 to the lower area of ​​the reverse slope tower base, thus easily and conveniently conveying the concrete to the reverse slope tower base. This not only effectively reduces the construction difficulty but also greatly improves the construction quality. This patented technology is simple to construct and can be reused repeatedly, making it highly valuable for promotion.

[0032] Optionally, in one possible implementation, the conduit fixing mechanism 2 further includes an adjusting rod 11. The support plate 8 has a threaded through hole adapted to the adjusting rod 11. The adjusting rod 11 is threadedly connected to the threaded through hole. The end of the adjusting rod 11 abuts against the insert plate 6. The operator can rotate the adjusting rod 11 to adjust the angle of the conduit fixing mechanism 2, thereby adapting to different construction environments.
