The invention discloses an explosion-proof door for civil defence. The explosion-proof door for civil defence comprises a door frame embedded into a wall body, a door body in the door frame, first rotary pieces which are arranged on the door frame and used for opening and closing the door body, an explosion-proof structure arranged on the door body, latch structures fixed to the door body and a concrete layer, wherein the inside of the door body is filled with the concrete layer, and according to the material formulation, per cubic meter of the concrete layer is prepared from 482 kg of ordinary cement 425, 200 kg of water, 0.45 m<3> medium-coarse sand and 0.79 m<3> of rubbles with the size of 10-30 mm<3> in a water cement ratio of 0.41. According to the explosion-proof door, it is ensuredthat the cement poured into the door body can spread over every corner in the door body by adjusting the inside cement, no grouting dead corner is generated, it is ensured that the cement can be closely attached to the inner wall due to low shrinkage, and moreover, the strength of the cement is ensured. Therefore, the overall crushing resistance of the door body is effectively improved, and due tothe high durability, the service life of the door for civil defence is ensured, and the maintenance cost is reduced.
本发明公开了一种防爆波人防门，包括嵌设于墙体内的门框、设于所述内的门体、设于所述门框上开合所述门体的第一旋转件、设于所述门体上的防爆波结构、用于固定所述门体的插销结构、填充于所述门体内部的混凝土层；所述混凝土层的材料配方为:所述混凝土层的材料配方为:425普通水泥、水灰比0.41、碎石粒径10~30mm³、中粗砂；每立方混凝土用料：水泥482㎏、水200㎏、中粗砂0.45m³、碎石0.79m³；本发明通过对于内部混凝土的调整，从而保证了浇筑于门内的混凝土能遍布门内各个角落，避免灌注死角的出现，收缩性小保证了混凝土能与内壁产生紧密贴合，同时保证了混凝土的强度，从而有效提高了门体整体的抗挤压能力，耐久性强保证了人防门的使用寿命，减少维护成本。
