Temporary flood barrier constructed by soil engineering filling bags and gate-shaped steel frames

Abstract

A temporary flood barrier constructed by soil engineering filling bags and gate-shaped steel frames comprises a standby water stopping dam and a plurality of gate-shaped fixing frames, wherein the standby water stopping dam is constructed by a plurality of sequentially stacked soil engineering filling bags to be filled with water from bottom to top; the structures of the soil engineering filling bags are the same; the gate-shaped fixing frames are used for fixing the stacked soil engineering filling bags; the gate-shaped fixing frames are arranged at equal intervals according to the lengths of the soil engineering filling bags, and sleeve the outer periphery of the water stopping dam constructed by the soil engineering filling bags in a clamped manner at equal intervals; and column legs of each gate-shaped fixing frame are inserted in the ground or a riverbed. According to the temporary flood barrier constructed by the soil engineering filling bags and the gate-shaped steel frames, the watertight soil engineering filling bags and gate-shaped steel frame supporting structures for maintaining the whole structure are adopted to establish a stable and multilayered filling bag structure, and can be used for quickly constructing water stopping facilities such as temporary dams, flood barriers and cofferdams.

Description

technical field [0001] The invention relates to a water retaining dike device. In particular, it relates to a temporary flood control barrier constructed by using geotechnical filling bags and door-shaped steel frames. Background technique [0002] In recent years, due to sea level rise caused by global warming and other natural and man-made reasons, disasters such as tsunamis and floods have occurred from time to time, and accidents of dike and dam failures have frequently appeared in the newspapers. Urban underground facilities, such as subways, underground shopping malls, etc., sometimes have water gushing and submersion accidents caused by urban floods. Therefore, it is imperative to choose a reasonable and feasible water-retaining structure in the above-mentioned disaster-prone areas such as inland river basins and coastal coasts, docks, port areas, and urban underground spaces. [0003] In addition, for some special cases, such as: in case of severe weather condition...

AI Technical Summary

Problems solved by technology

However, the filling material of existing geotechnical filling bags is soil or sand. Some published patents such as those listed in Table 1 use soil or sand as filling materials, resulting in relatively difficult installation and disassembly of water retaining facilities. It is time-consuming and laborious, and it is not conducive to the reuse of materials; Table 2 lists some invention patents using water as filling material, but it is only applicable to the case of shallow water level, and there is stability in the case of only one side retaining water and high water level Insufficient danger; there are also water-retaining structures such as rubber dams, which improve the water-retaining capacity of the overall structure by anchoring the bottom of the filling bag to the foundation surface. The anchoring forms include unilateral anchoring and bilateral anchoring. Although the method has a certain improvement in stability, it needs to carry out foundation construction in advance, requires a certain construction time and conditions, and has high requirements for the tensile performance of the local area of ​​the geotextile bag, and is not suitable for the construction of temporary dams.
