It is installed one by one on the tunnel wall during the tunneling process of the shield machine and eventually forms part of the tunnel structure. Usually, the shield segment is cast with concrete and has a specific shape and size. After the casting is completed, the shield segment needs to be steamed to improve the strength of the segment. During the steaming process, the concrete in the shield segment will undergo a hydration reaction to form crystals, which will gradually harden and strengthen the concrete, improving its compressive strength and durability. At the same time, concrete will shrink during the hardening process. Steaming can control and reduce the shrinkage of concrete and avoid problems such as cracks and deformation.

[0003] Therefore, steam curing of pipe segments is an indispensable part of the pipe segment production process.

[0029] See also Figure 1-3 The utility model provides an environmentally friendly pipe segment steaming curing equipment, including a box body 1, a gas outlet 5 is provided on the top of the box body 1, a partition plate 19 is provided in the box body 1, a placement plate 8 for placing pipe segments 7 is provided on the partition plate 19, the upper surface of the placement plate 8 is recessed downward to form a water collecting tank 9, a steam system is also provided on the partition plate 19, a water recovery system is provided below the partition plate 19, the water recovery system includes a sedimentation tank 12 arranged below the partition plate 19 and a collection tank 16 arranged below the sedimentation tank 12, a water outlet 14 and a cleaning port are respectively provided at both ends of the sedimentation tank 12, the water outlet 14 is located above the collection tank 16, and at least one sewage pipe 10 is connected to the bottom surface of the placement plate 8, and the lower end of the sewage pipe 10 passes through the partition plate 19 and is connected to the sedimentation tank 12.

[0030] When the present embodiment is used, when it is necessary to steam-cure the shield segment 7, the shield segment 7 to be steam-cured is placed on the placement plate 8, the steam system is turned on, and the steam generated by the steam system is evenly distributed on the segment 7 to heat and steam the segment 7. During the steam-curing process, the water after the steam condensation flows through the surface of the segment 7 and takes away the granular impurities on the surface of the segment 7 and then flows into the water collection tank 9, and enters the sedimentation tank 12 through the sewage pipe 10 connected to the water collection tank 9 for sedimentation and separation. After sedimentation and separation, the water without impurities enters the collection tank 16 through the water outlet 14, and the settled granular impurities are cleaned through the cleaning port. The whole process can effectively collect the sewage on the surface of the segment 7, recycle the clean condensed water and water with less impurities, reduce the waste of water resources, and save costs.

[0031] In this embodiment, a drain pipe 17 is connected to the bottom of the collection pool 16. The drain pipe 17 passes through the side wall of the box body 1 and then extends out of the box body 1, so as to facilitate the collection and treatment of the clean condensed water after sedimentation and the condensed water with less impurities for reuse, thereby reducing the difficulty of cleaning the collection pool 16.

[0032] In this embodiment, three sewage pipes 10 are provided, and the three sewage pipes 10 are evenly arranged at the left, middle and right positions of the placement plate 8. The three sewage pipes 10 are respectively used to guide the sewage at the left, middle and right positions of the water collection tank 9 into the sedimentation tank 12, which can reduce the residence time of the sewage in the water collection tank 9, thereby preventing the sediment from settling in the water collection tank 9.

[0033] As a further description of the above embodiment, a clean water groove 15 is provided on the partition plate 19 along the circumference of the partition plate 19 , and a leakage hole 20 is provided at the bottom of the clean water groove 15 , and the leakage hole 20 is located above the collection pool 16 .

[0034] When this embodiment is used, during the steaming process, condensed water will be formed after the steam collides with the inner wall of the box body 1. After condensation, except for the condensed water entering the water collecting tank 9, the condensed water in the rest of the box body 1 will fall onto the partition plate 19. If the condensed water on the partition plate 19 cannot be processed in time, the normal use of the equipment will be affected. Therefore, in order to solve this problem, in this embodiment, a clean water tank 15 with a leakage hole 20 is provided on the partition plate 19. The condensed water falling on the partition plate 19 flows into the clean water tank 15, and flows into the collection tank 16 through the leakage hole 20 at the bottom of the clean water tank 15 for recycling.

[0035] As a further description of the above embodiment, at least two cushion blocks 11 are provided between the partition plate 19 and the placement plate 8 .

[0036] When this embodiment is used, the pad 11 is used to raise the height of the placement plate 8, so as to facilitate the water in the box body 1 to flow into the clean water tank 15. At the same time, this design can facilitate the replacement of the placement plate 8. The appropriate placement plate 8 can be selected according to different pipe segments 7.

[0037] As a further description of the above embodiment, the steam system includes two symmetrically arranged steam distributors 6, both of which are arranged on the partition plate 19, and a plurality of nozzles are arranged on the opposite surfaces of the two steam distributors 6. The steam distributors 6 are connected to a steam generator through a steam pipe, and the steam generator is arranged outside the box body 1.

[0038] When this embodiment is used, the two steam distributors 6 and the plurality of nozzles thereon can spray steam to the tube segments 7 from both sides, thereby improving the steaming effect on the tube segments 7 .

[0039] The steam generator adopts the existing technology, so the present embodiment does not further describe its structure and the connection mode between it and the steam distributor 6. In the present embodiment, the steam generator is a LDR0.25-D type steam generator.

[0040] As a further description of the above embodiment, the bottom of the sedimentation tank 12 is inclined, and the water outlet 14 is arranged at an end of the sedimentation tank 12 that is inclined upward. The bottom of the sedimentation tank 12 is provided with a plurality of spoiler plates 21, and the spoiler plates 21 are in a continuously curved structure. The cleaning port is located at an end of the sedimentation tank 12 that is inclined downward, and the cleaning port penetrates the side wall of the box body 1, and a plug 13 is arranged in the cleaning port.

[0041] When this embodiment is used, the bottom of the sedimentation tank 12 is tilted to facilitate the impurities to flow downward under their own gravity, preventing the impurities from accumulating at the bottom of the sedimentation tank 12 and increasing the difficulty of cleaning the impurities and the sedimentation tank 12. The sedimentation tank 12 is used to settle the sand and dust in the sewage and gather them on the side of the sedimentation tank 12 that is tilted downward. The spoiler 21 at the bottom of the sedimentation tank 12 is used to reduce the flow rate of water and sediment in the sedimentation tank 12, thereby facilitating the sedimentation.

[0042] In this embodiment, the side of the settling tank 12 that is inclined upward contains less silt and can be recycled, and this part of water is introduced into the collection tank 16 through the water outlet 14. The side of the settling tank 12 that is inclined downward accumulates silt. After the settling tank 12 is used, the silt in the settling tank 12 is discharged by opening the cleaning port. The plug 13 is used to plug the cleaning port. The design of the cleaning port can facilitate the cleaning of the settling tank 12.

[0043] As a further description of the above embodiment, a steam recovery system is provided on one side of the top of the box body 1, and the steam recovery system includes an air extractor 3, which is arranged outside the box body 1, and the two ends of the air extractor 3 are respectively connected to the condensation box 2 and the distribution head 4 after penetrating into the box body 1 through pipelines. The condensation box 2 is arranged on the top of the inner wall of the box body 1, and the distribution head 4 is arranged just above the placement plate 8. The air inlet of the condensation box 2 is located at the top of one side of the condensation box 2, and a water leakage pipe 18 is provided at the bottom of the condensation box 2.

[0044] When this embodiment is used, the vacuum pump 3 is used to draw the steam in the box body 1 into the condensation box 2 so that part of the steam condenses into water. The condensed water flows out from the leaking pipe 18 at the bottom of the condensation box 2 and is discharged through the leaking holes 20 in the clean water tank 15 in turn, so as to facilitate the collection and recycling of this part of the water. Then the vacuum pump 3 sends the steam into the distribution head 4 and discharges it from the top of the placement plate 8. This part of the steam can fully contact the tube sheet 7 again, thereby further improving the steaming effect. The setting of the steam recovery system can increase the residence time of the steam in the box body 1, thereby improving the steaming effect.

[0045] As a further description of the above embodiment, a baffle is provided in the condensation box 2 , and the baffle forms a U-shaped space in the condensation box 2 .

[0046] When the present embodiment is used, steam enters the condensation box 22 and hits the baffle plate, thereby fully contacting the baffle plate and condensing into water, which can improve the recovery effect.

[0047] In summary, the utility model has good steaming effect of the tube segments, good water purification and collection effect, can effectively recycle water and reduce the waste of water resources. Therefore, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
