It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] Please also read Figure 1 , Figure 2 and Figure 5Now, the pipeline device for steam maintenance of bridge piers provided by the utility model is described. The pipeline device for steam maintenance of bridge piers includes an annular pipe 1, an air inlet pipe 2 and a plurality of air outlet pipes 3. The annular pipe 1 is arranged horizontally, and the annular pipe 1 is used to be sleeved outside the bridge pier 10. The air inlet pipe 2 is arranged horizontally, and one end of the air inlet pipe 2 is fixedly connected to the annular pipe 1 and communicated with the inside of the annular pipe 1. A plurality of air outlet pipes 3 are arranged in sequence around the circumference of the annular pipe 1, the air outlet pipe 3 is arranged vertically and fixed on the annular pipe 1, the air outlet pipe 3 is communicated with the inside of the annular pipe 1, and a plurality of air outlet holes 31 are provided on the side wall of the air outlet pipe 3, and the plurality of air outlet holes 31 are arranged in sequence in a vertical direction. The air outlet holes 31 face the bridge pier 10, and the upper end of the air outlet pipe 3 is closed.

[0025] Compared with the prior art, the pipe device for steam maintenance of bridge piers provided by the utility model has an annular pipe 1 and a plurality of air outlet pipes 3 arranged in a greenhouse, and an air inlet pipe 2 extends out of the greenhouse and the free end is connected to the steam generator. The steam generated by the steam generator enters the annular pipe 1 through the air inlet pipe 2, and then is ejected through the air outlet holes 31 on the plurality of air outlet pipes 3. Since the plurality of air outlet pipes 3 are arranged in sequence at intervals around the circumference of the annular pipe 1, the steam ejected from the air outlet holes 31 on the plurality of air outlet pipes 3 can be evenly distributed around the bridge pier 10, and since the plurality of air outlet holes 31 on the air outlet pipes 3 are arranged in sequence at intervals along the vertical direction, the steam ejected from the plurality of air outlet holes 31 can be evenly distributed along the vertical direction, so that the steam in the greenhouse can be evenly distributed, thereby avoiding the problem of uneven steam distribution in the greenhouse.

[0026] In some embodiments, see Figure 1 The pipeline device for steam curing of bridge piers also includes a closing plate 4. The closing plate 4 is horizontally arranged and located above the bridge pier 10. The closing plate 4 fits with and covers the upper end surfaces of all the outlet pipes 3. The upper end of the outlet pipe 3 is closed by the closing plate 4.

[0027] In some embodiments, see Figure 4 and Figure 6 The pipeline device for steam maintenance of bridge piers also includes a plurality of connection units 5, which correspond to the plurality of outlet pipes 3 one by one, and the connection units 5 include an electric heating rod 51. The electric heating rod 51 is inserted into the corresponding outlet pipe 3 and has an annular gap 32 with the outlet pipe 3. The electric heating rod 51 penetrates the closing plate 4 and is fixedly connected to the closing plate 4. The closing plate 4 and the electric heating rod 51 cooperate to close the upper end of the outlet pipe 3. The heat emitted by the electric heating rod 51 can prevent the steam from condensing into water droplets during the rising process, so that the outlet hole 31 above can smoothly spray steam.

[0028] In some embodiments, the feature connection unit 5 may be implemented as follows: Figure 4 and Figure 6See the structure shown. Figure 4 and Figure 6 The connection unit 5 further includes a limiting tube 52. The limiting tube 52 is slidably sleeved outside the corresponding air outlet pipe 3 and fixedly connected to the closing plate 4. The limiting tube 52 can limit the movement of the closing plate 4 in the horizontal direction.

[0029] In some embodiments, the feature connection unit 5 may be implemented as follows: Figure 4 and Figure 6 See the structure shown. Figure 4 and Figure 6 The connection unit 5 further includes a fixing plate 53 and a connecting bolt 54. The fixing plate 53 is horizontally arranged and located below the limiting tube 52. The fixing plate 53 is fixedly connected to the corresponding air outlet pipe 3, and the fixing plate 53 is provided with a threaded hole. The screw of the connecting bolt 54 is passed through the closing plate 4 and is threadedly connected to the threaded hole. The closing plate 4 is fixed to the air outlet pipe 3 by the threaded connection between the connecting bolt 54 and the fixing plate 53, thereby preventing the closing plate 4 from falling off the air outlet pipe 3.

[0030] In some embodiments, see Figure 1 and Figure 5 The pipeline device for steam curing of bridge piers also includes an annular plate 6 and a plurality of fixed columns 7. The annular plate 6 is arranged horizontally, and the annular plate 6 is used to be sleeved outside the bridge pier 10 and is located below the annular pipe 1. The plurality of fixed columns 7 are located between the annular plate 6 and the annular pipe 1. The fixed columns 7 are arranged vertically and the two ends of the fixed columns 7 are respectively fixedly connected to the annular plate 6 and the annular pipe 1. The annular plate 6 is fixed to the annular pipe 1 through the fixed columns 7. The annular plate 6 is placed on the ground, and the annular pipe 1 is supported by the annular plate 6. Since the contact area between the annular plate 6 and the ground is large, the resistance during movement is large, which is conducive to keeping the device at a preset position.

[0031] In some embodiments, see Figure 1 , Figure 3 and Figure 5 The annular tube 1 and the annular plate 6 are both arranged along the same vertical bisecting plane. The annular tube 1 is divided into two first split parts 11, and the annular plate 6 is divided into two second split parts 61. The two first split parts 11 are detachably connected. After the two first split parts 11 and the two second split parts 61 are sleeved outside the bridge pier 10, the two first split parts 11 are connected together, so that the annular tube 1 and the annular plate 6 are sleeved outside the bridge pier 10, which is more convenient. In this embodiment, the first split part 11 is fixedly connected to the second split part 61 located on the same side of the vertical bisecting plane through the fixing column 7.

[0032] In some embodiments, the second split portion 61 can be configured as follows: Figure 3 See the structure shown. Figure 3The second body part 61 is provided with a plurality of through holes 62. Nails for inserting into the ground are inserted into the through holes 62, thereby fixing the second body part 61 to the ground, thereby preventing the device from tipping over.

[0033] In some embodiments, see Figure 3 , connecting flanges 12 are fixed at both ends of the first sub-body 11. Two connecting flanges 12 belonging to different first sub-body 11 on the same side of the pier 10 are connected together by multiple sets of fixing bolts 8 and fixing nuts 9, thereby realizing the detachable connection of the two first sub-body 11.

[0034] In some embodiments, the closing plate 4 is made of heat-insulating material, so that the closing plate 4 can be used as the roof of the greenhouse for insulation.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
