[0027] The invention will be further described below in conjunction with specific embodiments:

[0028] like Figure 1 As shown, the present embodiment provides a communication pipeline base bed casting tool, which can be used to replace the wooden formwork used in the traditional communication pipeline base bed construction. The communication pipeline base bed casting tool includes two side templates 10 arranged in parallel with each other, two first columns 11 fixedly connected to each side template 10 one by one, two second columns 12 fixedly connected to the side template 10 one by one, a first connecting rod 20 connected between the two first columns 11, and a second connecting rod 30 connected between the two second columns 12. On the same side template 10, the first column 11 and the second column 12 are respectively located at the two ends of the side template 10 or near the two ends thereof, and a mold cavity for pouring concrete is formed between the two side templates 10. Each connecting rod is located above the mold cavity to avoid interference with the mold cavity. Specifically, the lower ends of the first column 11 and the second column 12 are fixedly connected to the corresponding side template 10, and the upper ends are fixedly connected to the corresponding connecting rods, and each column is preferably arranged vertically with the corresponding side template 10.

[0029] Preferably, the side formwork is made of channel steel or square steel with a width of 80 mm. Of course, if channel steel is used, the openings of the grooves on the two channel steels should be arranged back to back.

[0030] Preferably, the lower end of each first column 11 or each side template 10 is rotatably connected with a swing rod 40, that is, there are two swing rods 40, and each swing rod 40 is provided with a roller 41 at one end away from the corresponding side template 10, and a pressure rod 42 is fixedly connected to the rod body of each swing rod 40, and an angle is formed between each pressure rod 42 and the corresponding swing rod 40, and a third connecting rod 50 is connected between the two pressure rods 42. When the side template 40 is arranged vertically and its length direction is horizontal, the pressure rod 42 is gradually tilted upward from one end connected to the corresponding swing rod 40 to the other end in a direction away from the side template 40, and the third connecting rod 50 is connected to the upper end of the pressure rod 42 and used as a handle. In addition, the upper end of each first column 11 is fixedly connected to a spring 60, and the end of each spring 60 that is not connected to the corresponding first column 11 is fixedly connected to the corresponding pressure rod 42 or the end of the corresponding rocker arm 40 provided with the roller 41. In this embodiment, the spring 60 is fixedly connected to the pressure rod 42 as an example for explanation. At this time, the spring 60 is indirectly fixedly connected to the rocker arm 40 by being fixedly connected to the pressure rod 42. In the initial state, the rocker arm 40 is arranged to tilt upward under the tension of the spring, so that the roller 41 does not contact the ground.

[0031] Preferably, the first connecting rod 20, the second connecting rod 30 and the third connecting rod 50 are all telescopic rods, which include an outer tube sleeve 21 and an inner tube body 22 slidably inserted in the outer tube sleeve 21, wherein a positioning hole is provided on the inner tube body 21, and the positioning hole is preferably a threaded hole, and the outer tube sleeve 22 is provided with more than two fastening holes 23 along its length direction, and a positioning pin 24 is inserted in one of the fastening holes 23 and inserted in the positioning hole at the same time, and the positioning pin 24 is preferably a bolt, so that the positioning pin 24 is spirally connected in the threaded hole by the bolt to help prevent the positioning pin 24 from loosening. In addition, a scale line is provided on the outer tube sleeve 21, so that the user can intuitively know the position and size of the fastening hole 23.

[0032] When in use, the distance between the two side templates 10 is adjusted by adjusting the telescopic rods, and then the entire communication pipe base bed casting tool is placed in the pre-dug groove, and concrete can be poured into the mold cavity; after the concrete solidifies, the third connecting rod 50 is held by hand and pressed downward, so that it drives the swing arm 40 to rotate downward through the pressure rod 42, and then the roller 41 is pressed against the bottom of the groove, and one end of the side template 10 is lifted up through the swing arm 40, so that the side template 10 is separated from the concrete, and the communication pipe base bed casting tool can be taken out. In this process, the spring 60 will be stretched. When the communication pipe base bed casting tool is taken out, the swing arm 40 is reset under the action of the spring 60.

[0033] The present invention is described in detail above with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, such as changing the spring 60 in the above embodiment to an elastic rope, etc., which all belong to the protection scope of the present invention.
