Problems solved by technology

However, the current method has the following problems: one is that the method of using piles or screw anchors takes a lot of time and cannot effectively contain the development of the breach; The loss rate of interception materials such as thrown stones or sandbags is relatively high, which cannot effectively seal the crevasse
Due to the defects of the current breach rescue technology, sometimes in order to reduce the overflow flow of the breach, the way of sinking ship or truck is used to intercept the flow. However, under the interference of the flow velocity of the breach, it is often difficult to locate in this way
From this, it can be seen that the existing sealing technology takes too much time, the construction is difficult, and the loss rate of interception materials is high. In addition, the way of shipwreck interception and driving interception poses a major threat to the life safety of rescuers

Embodiment 1

[0030] The prefabricated extensible fence used for rapid closure of the breach described in this embodiment has a structure such as figure 2 , Figure 4 , Figure 5 , Image 6 As shown, it is composed of several fence units and several connecting bars 7 . The fence unit is composed of a cuboid horizontal seat 1, five columns 2 whose main body is cylindrical and whose lower end is a cone, and a cylindrical horizontal bolt 3. The horizontal seat is provided with a column socket 4 that runs through the top and bottom surfaces of the horizontal seat and whose shape and size match the column, and a horizontal bolt socket 6 that runs through the end faces of both ends of the horizontal seat and matches the shape and size of the horizontal bolt. The part between the two column sockets is a hollow structure; the number of the column sockets is the same as that of the columns, each column socket is evenly distributed in a row along the length direction of the horizontal seat and th...

Embodiment 2

[0033] The prefabricated extendable fence used for rapid closure of the breach described in this embodiment is composed of several fence units and several connecting strips 7 . The fence unit structure is as figure 1As shown, it is composed of an elliptical cylindrical horizontal seat 1, five main bodies of a quadrangular prism, a column 2 with a quadrangular pyramid at the lower end, and a cylindrical horizontal bolt 3. The horizontal seat is provided with a column socket 4 that runs through the top and bottom surfaces of the horizontal seat and whose shape and size match the column, and a horizontal bolt socket 6 that runs through the end faces of both ends of the horizontal seat and whose shape and size match the horizontal bolt; The number of columns is the same as the number of columns, and the column jacks are evenly distributed and arranged in a row along the length direction of the horizontal seat, and their center lines are parallel to each other. The center line of ...

Abstract

The invention discloses an assembled extensible fence for quickly blocking a breach. The assembled extensible fence comprises fence units and multiple connecting bars; each fence unit consists of a transverse base, multiple stand columns and a transverse bolt; the transverse base is provided with stand columns insertion holes penetrating through the top surface and the bottom surface of the transverse base and matched with the stand columns in shape and size, and transverse bolt insertion holes penetrating through the end surfaces of two ends of the transverse base and matched with the transverse bolt in shape and size; the stand column insertion holes are as many as the stand columns; all the stand column insertion holes are uniformly arranged in one row in the length direction of the transverse base, and the center lines thereof are parallel to each other; the center lines of the transverse bolt insertion holes are perpendicular to and intersected with the center lines of all the stand column insertion holes; fixed insertion holes are formed in the stand columns; and the center lines of the solid insertion holes are perpendicular to and intersected with the center lines of the stand columns. The fence can realize quick emergency construction of wrapping heads and safe blockage, improves the emergency safety, and reduces the construction difficulty of sudden breach closure blockage and the loss rate of closure materials.

Description

technical field [0001] The invention belongs to the technical field of interception in water conservancy and hydropower projects, and in particular relates to an assembled extendable fence for rapid sealing of breaches Background technique [0002] When a flood disaster occurs, under the long-term immersion and impact of the flood, and under the improper rescue and protection during the flood season, the embankment of rivers and lakes will burst. Levee breaches are extremely harmful to regional social and economic development and the safety of people's lives and property. Therefore, it is necessary to take effective measures against embankment breaches, quickly stop the breach from continuing to develop, and seal the breach as soon as possible, which is of great significance for reducing the degree of disaster damage. In the case of high water level during the flood season, emergency rescue of dike breaches requires intercepting and blocking the water flow at the entrance of...
