[0002] In industries such as metal smelting and machinery manufacturing, casting pits are critical infrastructure for the pouring and cooling of molten metal, directly impacting casting quality, production safety, and process efficiency. Through specific structural design, they support the pouring of high-temperature molten metal (such as steel, iron, and aluminum alloys) while simultaneously controlling cooling, collecting waste residue, and ensuring safety. They are the core link connecting metal smelting and casting. Whether it's continuous casting of steel billets in steel mills, engine block casting in automobile factories, or the production of large components in heavy machinery, casting pits play an irreplaceable role.

[0003] Under normal circumstances, waterproofing treatment is required before using the casting pit. Usually, the pit is first sanded and then coated with waterproof paint. The walls should be constructed first, followed by the floor, and both should be coated with blue flexible waterproof paint.

[0004] Existing technologies typically employ the method of applying waterproof coatings to make the casting pit waterproof. However, in actual use, since the waterproof coating needs to be constantly immersed in water, it may be affected by factors such as vibration or changes in water temperature during the casting process. Over time, this may cause the waterproof coating to crack, leading to water seepage. Utility Model Content

[0025] Furthermore, the substrate 1 uses C35 or higher strength grade compensating shrinkage concrete, and incorporates KL-200 inorganic nano crack-resistant and seepage-proof agent to reduce the peak hydration heat and improve the crack resistance of the concrete. The internal steel plate 401 is pre-embedded and reinforced with anchor rods 402, thereby improving the stability of the entire casting pit.

[0026] Specifically, a sealing layer 403 is fixedly installed on one side of the steel plate 401, and a waterproof coating 404 is embedded in the outer wall of the sealing layer 403.

[0027] Furthermore, after pre-embedding the steel plate 401 with a sealing layer 403 that is in the same material as the substrate 1 and leveling the storage pool 3, a waterproof coating 404 is applied to achieve a waterproof effect. At the same time, the material of the thickened layer 2 is the same as that of the substrate 1, increasing the overall thickness.

[0028] Specifically, a polypropylene layer 405 is embedded at the bottom of the inner part of the storage pool 3, and a thickened part 406 is embedded on one side of the polypropylene layer 405.

[0029] Furthermore, after leveling the base of the storage pool 3, a polymer cement-based coating is applied to repair minor cracks in the base layer and to provide adhesion to the polypropylene layer 405, thus initially achieving a waterproof effect.

[0030] Specifically, an SBS waterproof layer 407 is embedded on the other side of the thickened part 406, and a leveling layer 408 is embedded on the outer wall of the SBS waterproof layer 407.

[0034] Specifically, the SBS waterproof layer 407 is bonded to the polypropylene layer 405, and the polypropylene layer 405 is bonded to the thickened part 406.

[0035] Furthermore, in addition to adhesive, a 2mm thick polyurethane waterproof coating is applied between the SBS waterproof layer 407, the polypropylene layer 405, and the thickened portion 406 to facilitate tight adhesion and further improve the waterproof effect.

[0036] In use, the stability of the entire substrate 1 is first improved by the cooperation of steel plate 401 and anchor rod 402. The steel plate 401 is then covered and leveled by sealing layer 403. Then, polypropylene layer 405, thickened part 406, SBS waterproof layer 407 and waterproof coating 404 are laid in sequence at the bottom of the inside of the storage pool 3. The overall sealing effect is further improved by their mutual adhesion. A mud leveling layer 408 is provided between SBS waterproof layer 407 and waterproof coating 404 to keep it smooth and improve the coating effect of waterproof coating 404. It is also used in conjunction with sealing plate 409 to protect waterproof coating 404 by interlocking with block 410 and slot 411.

[0037] In summary, firstly, the bottom of the storage pool 3 is layered and bonded together with a polypropylene layer 405, a thickened section 406, and an SBS waterproof layer 407. Then, after leveling with a leveling layer 408, a waterproof coating 404 is applied. This maintains the overall waterproof effect of the casting pit, preventing seepage.
