Description

Technical Field

[0001] The utility model relates to the field of concrete, in particular to an underground engineering concrete side wall structure. Background Art

[0002] At present, a Chinese patent with authorization announcement number CN213448562U discloses a basement anti-seepage and anti-cracking reinforced concrete wall, wherein the reinforced concrete wall is formed by reinforced concrete doped with inorganic silicon waterproof material, a cement-based penetrating crystalline waterproof coating layer is applied to the inner wall surface and the outer wall surface of the reinforced concrete wall, an outer wall insulation layer is arranged on the outer wall surface of the reinforced concrete wall, and a rammed earth layer is arranged on the outer side of the outer wall insulation layer; while the structure is stable, the inorganic silicon waterproof material doped in the reinforced concrete of the reinforced concrete wall and the cement-based penetrating crystalline waterproof coating layer applied to the inner and outer wall surfaces of the reinforced concrete wall have the functions of automatically healing micro-cracks below 0.4 mm, reducing crack shrinkage, and enhancing the mid- and late-stage strength and density of reinforced concrete, the reinforced concrete structural layer can be automatically repaired to ensure the overall construction quality, with high tensile strength and naturally increased crack resistance, thereby achieving a permanent waterproof and anti-cracking effect, and the construction is more convenient and not affected by changes in ambient temperature.

[0003] This type of basement anti-seepage and anti-cracking reinforced concrete wall structure is simple, but the basement is a civil defense project, and sandbags and other civil defense equipment need to be stored. This type of basement anti-seepage and anti-cracking reinforced concrete wall structure is obviously unable to store sandbags, so it can only be placed on the ground. On the one hand, the sandbags will occupy the activity space of the basement, and on the other hand, they will be easily affected by moisture and affect the quality and service life of the sandbags. Utility Model Content

[0004] In view of this, the utility model aims to provide a concrete side wall structure for underground engineering, so as to extend the service life of sandbags and not easily affect the quality of the sandbags.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a concrete side wall structure of an underground engineering, including a concrete wall, a storage cavity is opened on the inner wall surface of the concrete wall, a moisture-proof board is fixedly connected to the inner wall of the storage cavity, an insulation board is connected to the side of the moisture-proof board facing the storage cavity, the insulation board and the moisture-proof board are connected by a quick-release structure, an installation groove is opened at the opening of the storage cavity, a cover plate is connected to the inner wall of the installation groove, a sealing ring is fixedly connected to the edge of the cover plate, a positioning groove is opened on the side wall of the installation groove, and the sealing ring is embedded in the positioning groove.

[0006] To implement the above technical solution, a storage cavity is opened on the inner wall of concrete, and a moisture-proof board is fixed on the inner wall of the storage cavity. The moisture-proof board can make the storage cavity have a better moisture-proof effect, and the insulation board improves the thermal insulation property, so that the sandbags can be moisture-proof and heat-insulating, so that the sandbags maintain good quality and extend their service life; through the setting of the quick-release structure, the insulation board can be quickly removed and installed from the moisture-proof board to adapt to the usage scenarios in extreme situations, the cover plate is embedded in the installation groove, and the sealing ring is embedded in the positioning groove, so that the storage cavity has a better sealing effect and the internal space of the storage cavity is not easily affected by moisture.

[0007] As a preferred solution of the utility model, a connecting hole is provided on the inner wall of the installation groove, a sliding hole is provided on the bottom wall of the connecting hole, the inner diameter of the sliding hole is larger than the inner diameter of the connecting hole, an anti-slip block is slidably connected in the sliding hole, a connecting rod is fixedly connected to the anti-slip block, and the connecting rod is connected to the side of the cover plate facing the installation groove.

[0008] To implement the above technical solution, the cover plate is moved away from the installation groove, the anti-slip block moves along the length direction of the sliding hole, and the connecting rod slides along the connecting hole. When the anti-slip block contacts the inner wall of the sliding hole, the cover plate is suspended through the pulling force of the connecting rod, thereby preventing the cover plate from being lost.

[0009] As a preferred solution of the utility model, the quick-release structure includes an L-shaped plate, a slide plate and a limit assembly, the two L-shaped plates are arranged opposite to each other and fixed on the surface of the moisture-proof plate, a slide groove is formed between the two L-shaped plates, one side of the slide plate is fixedly connected to the insulation board, the slide plate is slidably connected in the slide groove, and the end of the moisture-proof plate is connected to the insulation board through the limit assembly to limit the relative movement between the insulation board and the anti-slide plate.

[0010] To implement the above technical solution, the slide plate is moved along the length direction of the slide groove to make the insulation board and the moisture-proof board correspond to each other. Due to the limiting effect of the L-shaped plate, the insulation board is not easy to move toward the middle of the storage cavity. The setting of the limiting component makes it difficult for the insulation board and the moisture-proof board to be offset.

[0011] As a preferred solution of the utility model, the limit assembly includes a rotating rod, a rotating shaft, and a limit plate. The limit plate is arranged in an L shape and is fixed to the end of the moisture-proof plate. The rotating shaft is rotatably connected to the end of the insulation plate. One end of the rotating rod is fixed to the side wall of the rotating shaft, and the other end is embedded in the groove formed between the limit plate and the moisture-proof plate.

[0012] To implement the above technical solution, slide the insulation board along the length direction of the moisture-proof board, rotate the rotating rod, rotate the rotating shaft, and embed the rotating rod into the embedding groove to prevent the insulation board from being easily separated from the moisture-proof board; unscrew the rotating rod from the embedding groove to remove the insulation board from the moisture-proof board.

[0013] As a preferred solution of the utility model, the cover plate is provided with a water absorbing component for contacting with the ends of the moisture-proof plate and the heat-insulating plate.

[0014] By implementing the above technical solution, the water absorption component can further improve the dryness of the storage cavity.

[0015] As a preferred solution of the utility model, the water absorption component includes a sponge layer and a desiccant bag. The sponge layer is fixed on the surface of the cover plate and contacts the end of the moisture-proof plate and the end of the insulation plate. The sponge layer is provided with a placement groove for placing the desiccant bag.

[0016] To implement the above technical solution, the sponge layer is brought into contact with the ends of the moisture-proof board and the ends of the thermal insulation board to improve water absorption, and the desiccant bag further improves the water absorption effect.

[0017] As a preferred solution of the utility model, the moisture-proof board includes a PVC board.

[0018] By implementing the above technical solution, the PVC board has good waterproof and moisture-proof properties, so that water in the concrete is not easy to enter the middle part of the storage cavity.

[0019] As a preferred solution of the utility model, the thermal insulation board comprises a phenolic board.

[0020] By implementing the above technical solution, the phenolic board has good flame retardancy and heat preservation, and the phenolic board has a low density, which reduces the weight of the building. BRIEF DESCRIPTION OF THE DRAWINGS
