Description

Technical Field

[0001] The present invention relates to an underground water-blocking dam used in emergency situations during flood season. The underground garage includes underground parking lots, subway entrances and exits, underground warehouses, etc. The dam is arranged at the entrance of the underground garage. When a natural disaster occurs suddenly, it is necessary to effectively block the flood. The dam can be quickly assembled and effectively block water. It prevents vehicles and equipment in the underground garage from being damaged by water. At the same time, after use, it can be quickly restored without polluting the environment. The device also has the characteristics of repeated long-term use. Background Art

[0002] Usually, the traditional way to block water in an underground garage is to pile up sandbags, which are piled into a dam-type earth structure with a trapezoidal cross-sectional area to block water. Taking the subway entrances and exits as an example, sandbags are usually stored on the underground platform, moved to the ground for use during the flood season, and then moved back to the underground platform after the flood season. The transportation is time-consuming, labor-intensive, and pollutes the environment. At the same time, multiple people are required to be on duty during the flood season to leave enough manpower to build dams to block water when water suddenly comes.

[0003] In order to replace the sandbag damming method, many engineering technicians have also made a lot of efforts to design steel structure water-blocking gates, with rubber seals set on the left and right sides and bottom of the gate to stop water. When the water-blocking gate is closed to block water, the gap between the bottom of the gate and the ground becomes an important technical indicator. The larger the gap, the worse the water-blocking effect.

[0004] The following factors affect the gap between the bottom of the water-blocking door and the ground: the ground at the entrance of the garage is designed to be an arched structure for drainage convenience, which is high in the middle and low on both sides, resulting in uneven gap between the bottom of the door and the ground; the gap between the closed water-blocking door and the ground is also affected by the highest point in the fan-shaped area of ​​the ground from the starting end to the end during the opening and closing process.

[0005] Since the flatness of the ground corresponding to each door is different and the degree of fit between the door bottom and the ground is also different, when using rubber products as seals, it is necessary to make different designs for the ground rubber seals of each door. The separately produced rubber parts include molds, and the production cost is high, which is not conducive to factory production and therefore has not been widely used. Summary of the invention

[0006] In view of the above shortcomings, the present invention provides a split-type underground water-blocking dam. The split-type means that the dam body and the sealing member are separate independent components, including a dam body device and a sealing member, which are combined in combination when in use. The water-blocking dam can adapt to various complex terrain conditions. Due to the use of new sealing materials, the defects of rubber seals in water blocking are overcome, and the dam can be effectively and quickly assembled to block the invasion of floods.
