[0034] See also Figure 1The utility model provides a protective device 1 and a post-cast strip structure having the protective device 1. The post-cast strip structure includes a fixing part, and the fixing part forms a gap. In the utility model, the fixing part is a part of the main structure, and its material includes concrete. The gap formed by the fixing part is the construction joint, and its specific setting position and size are set according to the actual design and construction needs. Post-cast concrete is poured in the gap, that is, the post-cast strip 2 in the utility model. The pouring time is generally after the deformation and settlement of the fixed component 3 are stable. It is advisable to choose a time when the temperature is relatively low. Cement or concrete with a trace amount of aluminum powder added to cement can be poured. The strength grade should be one level higher than the component strength to prevent cracks from appearing between the new and old concretes and forming weak parts.

[0035] In this embodiment, a protective device 1 is mounted on the fixing member 3, and the protective device 1 is located above the post-cast strip 2, and is used to protect the steel bars and other components therein before pouring the post-cast concrete, and to prevent debris from entering the post-cast strip 2 area, causing pollution and affecting the structural strength of the post-cast strip. For details, please refer to Figure 1 and Figure 2 The protection device 1 includes a sealing cover and a water pipe 5. The two ends of the sealing cover in the lateral direction are respectively fixed on the fixing components 3 on both sides of the post-casting strip 2. A cavity is formed in the sealing cover, and the lower side of the sealing cover faces the top of the post-casting strip 2. The water pipe 5 is partially arranged in the cavity, and a water spray head 501 is connected to the water pipe 5. The water spray head 501 is arranged downward and exposed on the lower side of the sealing cover. During the construction of the post-casting strip 2, after pouring concrete in the post-casting strip 2 area, the sealing cover can be set above the post-casting strip 2 area. During the curing of the concrete in the post-casting strip 2 area, the water spray head 501 is used to spray water to it for curing. In this embodiment, the sealing cover does not need to be opened during the curing of the post-casting strip 2. Curing can be achieved by supplying water to the water pipe 5, thereby effectively improving the construction efficiency and avoiding the situation where the sealing cover cannot be reset after being opened, resulting in protection failure.

[0036] Preferably, a shock absorbing spring 101 and a shock absorbing base 102 are stacked in sequence from top to bottom between the sealing cover and the fixing member 3, so as to achieve a shock absorbing and buffering effect to prevent the fixing member 3 from being damaged when the sealing cover is under pressure.

[0037] For further information, please refer to Figure 1 and Figure 2 There are multiple water spray heads 501, the water pipe 5 extends in the horizontal direction, and each of the water spray heads 501 is connected to the water pipe 5 through a vertically extending spray pipe 502. Figure 3 and Figure 4The water pipe 5 has a water supply end extending out of the cavity, and the water supply end is connected to a water supply assembly through a sealing head 503, and the water supply assembly is used to supply water to the water pipe 5. There are many specific types of water supply assemblies, such as a valve body connected to an external tap water pipeline. In this embodiment, the water supply assembly is used to automatically supply water to the sprinkler head to achieve watering maintenance, thereby further improving construction efficiency.

[0038] Based on the previous embodiment, the sealing head 503 refers to a valve body component that conducts one-way from the water supply assembly to the nozzle. For details, please refer to Figure 4 The sealing head 503 is fixedly connected with a fixed block 506 inside, and a through hole is provided in the middle of the fixed block 506. A fixed block 505 is provided on the fixed block 506. The fixed block 505 has a first end and a second end respectively arranged on both sides of the through hole. The fixed block 505 is slidably installed on the fixed block 506 along the water conveying direction. The first end is provided with a limiting mechanism for limiting the movable stroke of the fixed block 505 along the water conveying direction. The second end is provided with a sealing sheet 504. The sealing sheet 504 has a first position of sealing the through hole and a second position of opening the through hole as the fixed block 505 slides. In this embodiment, when the water flows along the water conveying direction, the water pressure pushes the sealing sheet 504 to slide to the second position to open the through hole, and when the water flows in the reverse direction, the water pressure pushes the sealing sheet 504 to slide to the first position to close the through hole, so as to achieve the function of a one-way waterway and prevent the water from flowing back and damaging the water supply component.

[0039] On the basis of the previous embodiment, a connecting sleeve 5071 is further provided inside the sealing head 503, the connecting sleeve 5071 is located on the same side as the first end, a water-passing grille 5073 is provided at one end of the connecting sleeve 5071 close to the fixed stopper 506, a guide hole is provided in the middle of the water-passing grille 5073, a guide post 5074 is inserted in the guide hole, the guide post 5074 passes through the through hole and is connected to the sealing sheet 504. In this way, the connecting sleeve 5071 serves to limit the radial direction of the sealing sheet 504, so as to avoid the situation where the limiting sheet is stuck and fails after being offset.

[0040] Furthermore, the specific setting form of the limiting mechanism is as follows: the limiting mechanism includes a limiting protrusion 5072 protruding from the inner side of the fixing block 505, and a limiting groove arranged around the outer periphery of the connecting sleeve 5071, the limiting protrusion 5072 cooperates with the arc surface of the limiting groove, and is clamped in the limiting groove when the sealing sheet 504 is in the first position, and abuts against the fixed stopper 506 when the sealing sheet 504 is in the second position. In this way, the limiting protrusion 5072 and the limiting groove cooperate to limit the movable stroke of the sealing sheet 504 along the water conveying direction, so that the sealing effect and the conduction effect of the sealing head 503 are guaranteed.

[0041] In an alternative embodiment, see Figure 3 The water supply assembly includes a water tank 6 and a water pump 605. The water pump 605 is arranged below the water tank 6. The upper side of the water tank 6 is open and connected to a cover 601 in an openable manner. A handle 602 is fixedly connected to the upper side of the cover 601. A vertically extending water outlet pipe 603 is connected to the lower side of the water tank 6 in sequence. The water outlet pipe 603 is also connected to a horizontally extending drain pipe 604. A valve body is arranged on the drain pipe 604. The lower end of the water outlet pipe 603 is connected to the water inlet end of the water pump 605. The water outlet section of the water pump 605 is connected to the sealing head 503 through a connector 507. In this way, the water supply to the water delivery pipe 5 is realized by using the water tank 6 and the water pump 605. The water supply amount and water supply time can be adjusted by controlling the operation of the water pump 605. The operation is simple and easy to implement at the construction site.

[0042] Based on the above embodiment, the specific method of fixing the sealing cover to the fixing member 3 is not limited. Figure 1 The sealing cover is fixed to the fixing member 3 by a fixing assembly, and the fixing assembly includes a sealing steel bar 201 and a fixing hook 401. The sealing steel bar 201 is partially cast in the fixing member 3 and has a limit block protruding from the fixing member 3. The fixing hook 401 is slidably installed on both sides of the sealing cover in the horizontal direction, so as to have the ability to slide outward to a fixed position where the sealing cover is engaged with the limit block to fix the sealing cover, and to slide inward to an unlocked position where the sealing cover is disengaged from the limit block. Specifically, the sealing cover is provided with a fixing nut 403 and an adjusting bolt 402 screwed to the fixing nut 403 in the horizontal direction on both sides in the horizontal direction, respectively, and a connecting block 4 is connected to the adjusting bolt 402, and the fixing hook 401 is fixed to the lower side of the connecting block 4, so that the fixing hook 401 is slidably connected to the sealing cover in the horizontal direction along with the adjusting bolt 402.
