摘要

目的。设计一种在工厂条件下制造的防空洞,以进一步实现在战斗条件下确保士兵可靠保护的系统,同时考虑到前线的快速安装和易用性。方法。分析与综合,概括,概率论,决策论。结果。在分析国外防御工事建设经验的基础上,提出了一种由钢筋混凝土制成的圆柱形防空洞的建设,旨在减少其部署时间,增加机动性和强度,易于制造,并在各种敌对地点多种使用的可能性。科学的新奇。防空洞的结构为钢筋混凝土管(桶、集装箱、掩体),直径为2.5÷3.0 m,长度为4.0÷6.0 m,壁厚为150÷200 mm,其边缘横壁设有装甲门。在管道的腔内安装用于固定休息架的金属框架,该框架可在管道中转动并使用间隔螺钉固定在适当位置。以类似的方式,圆形装甲门被旋转并固定在横向墙上,周围有直径120-150毫米的6÷8孔,用于通风、照明和观察。进一步的研究方向是形成及时解决动力学问题的计算力组合,即D1组-利用LIRA-SAPR软件计算渐进倒塌时的应急荷载、爆炸、冲击、构件破坏计算。现实意义。将开发结果实施到确保在战斗条件下可靠保护士兵的系统中,将允许最大限度地减少由于使用在工厂条件下制造的圆柱形钢筋混凝土结构而造成的军事损失。

Construction of small protective fortification structures – factory-produced cylindrical reinforced concrete dugouts
Purpose. Design a dugout made in factory conditions for further implementation in the system of ensuring reliable protection of soldiers in combat conditions, taking into account quick installation and ease of use on the front line. Methods. Analysis and synthesis, generalisation, theory of probability, theory of decision-making. Results. Based on the analysis of foreign experience in the construction of fortifications, the construction of a cylindrical dugout made of reinforced concrete is presented, aimed at reducing the time of their deployment, increasing mobility and strength, ease of manufacture, and the possibility of multiple use in various places of hostilities. Scientific novelty. The structure of the dugout is a reinforced concrete pipe (barrel, container, bunker) with a diameter of 2.5÷3.0 m, a length of 4.0÷6.0 m and a wall thickness of 150÷200 mm with transverse walls at its edges that hold armoured doors . In the cavity of the pipe, a metal frame for fastening the shelves for rest is mounted, which can be turned in the pipe and fixed in the appropriate position using spacer screws. In a similar way, round armoured doors are turned and fixed in the transverse walls, around which 6÷8 holes with a diameter of 120-150 mm are provided for ventilation, lighting and observation. The further direction of the research is the formation of calculated combinations of forces for solving problems of dynamics in time, namely group D1 – calculation for emergency load, explosion, impact, failure of elements when calculating for progressive collapse with the help of LIRA-SAPR software. Practical significance. Implementation of the development results into the system of ensuring reliable protection of soldiers in combat conditions will allow to minimise losses among the military due to the use of reinforced concrete structures of cylindrical shape, manufactured in factory conditions.
