DETAILED DESCRIPTION

[0023] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-4 The shown device is a rotatable water testing and sealing device for a civil air defense opening structure, comprising: a sealing plate 1, reserved holes 2 for fastening bolts, supporting embedded parts 11, auxiliary installation hooks 8, water inlets and outlets 13, and an observation port 12.

[0025] The blocking plate 1 is arranged on the outside of the door opening 10 of the civil air defense structure. Figure 1 The blocking plate 1 is an integrated steel plate, with an auxiliary installation hook 8 provided on the top of the steel plate, a supporting embedded part 11 provided in the middle of the steel plate, and fastening bolt reserved holes 2 connected to the reinforcement embedded part 3 provided around the steel plate. Figure 3 shown.

[0026] Before the water test and sealing of the civil air defense entrance structure begins, the integrated sealing plate 1 should be further designed. The size, shape and material of the sealing plate 1 should be determined according to the size and shape of the door opening of the civil air defense entrance structure. At the same time, the position and number of the auxiliary installation hook 8, the supporting embedded parts 11 and the reserved holes 2 for fastening bolts should be determined to ensure that the sealing plate 1 can be firmly installed on the outside of the door opening of the civil air defense entrance structure. Before the concrete wall 5 around the civil air defense entrance is poured, the reinforcing embedded parts 3 should be embedded in the concrete wall 5 around the door opening 10. The position and number of the reinforcing embedded parts 3 should correspond to the reserved holes 2 for fastening bolts in the further design to ensure that the sealing plate 1 and the concrete wall 5 can be accurately connected later. Before pouring the civil air defense top floor slab outside the civil air defense entrance, the auxiliary installation hook 8 is embedded under the civil air defense top floor slab, and is embedded according to the reserved installation hook 8 on the top of the blocking plate 1; after the overall processing of the blocking plate 1 is completed, the blocking plate 1 that has passed the inspection is transported to the construction site, and is well protected to prevent damage during transportation; before the blocking plate 1 is installed, a series of preparatory work needs to be done. First, check whether the position of the reinforcement embedded parts 3 and the auxiliary installation hook 8 is accurate to ensure that it is consistent with the detailed design. Secondly, set sealing strips 4 at the position of the reinforcement embedded parts 3 and around the blocking plate 1 to improve the sealing between the blocking plate 1 and the concrete wall 5. At the same time, prepare the tools and equipment required for installation, such as electric hoists, bolts, etc. Use the electric hoist to lift the blocking plate 1 to the predetermined position through the auxiliary installation hook 8. During the lifting process, it is necessary to ensure that the blocking plate 1 fits tightly with the door opening of the civil air defense entrance structure without any gaps. Once the blocking plate 1 is in place, it is temporarily supported by diagonal support rods 7. One end of the support rod 7 is connected to the embedded support component 11, and the other end is fixed to the concrete floor slab outside the civil air defense entrance. After the support is fixed, the reinforcing embedded components 3 around the blocking plate 1 are tightened with fastening bolts. After the blocking plate 1 is completely fixed, the gap at the bottom of the blocking plate 1 is filled with waterproof mortar 9. After it is tightly and seamlessly connected, the civil air defense entrance is tested by filling the water through the water inlet and outlet 13 and the observation port 12. During the water filling process, it is necessary to observe whether the test water height meets the requirements and check the sealing and stability of the blocking plate 1. Any abnormalities should be promptly handled and recorded.

[0027] After the water test is completed, the water is discharged through the water inlet and outlet 13, and the blocking plate 1 is cleaned and checked to ensure that it is in good condition. Then, the blocking plate 1 is stored in a dry and ventilated warehouse so that it can be used next time.

[0028] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be pointed out that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
