Temporary water-retaining dam constructed with geotechnical filling bag and steel frame support system

Abstract

A temporary water-retaining dam built through geotextile filling bags and steel frame supporting systems comprises stand-by water-retaining dam bodies and a plurality of fixing frames, wherein each stand-by water-retaining dam body is formed by sequentially stacking a plurality of the geotextile filling bags of the same structure from bottom to top, and the geotextile filling bags are to be filled with water; the fixing frames are used for fixing the stacked geotextile filling bags, are arranged at equal intervals according to the length of the geotextile filling bags and surround the peripheries of the water-retaining dam bodies formed by stacking the multiple geotextile filling bags in a clamping mode at equal intervals, and the bottom of each fixing frame is fixed to the ground or the riverbed surface through bolts. According to the temporary water-retaining dam built through the geotextile filling bags and the steel frame supporting systems, a steel frame supporting structure adopting the water-proof geotextile filling bags and the water-proof steel frame supporting systems for reinforcing the lateral stability is used for building a stable multi-layer filling bag structure and can be used for fast constructing water-retaining facilities such as temporary dams, flood protection barriers and cofferdams.

Description

technical field [0001] The invention relates to a water retaining dike device. In particular, it relates to a temporary water-retaining dam constructed by using a geotechnical filling bag and a steel frame support system. Background technique [0002] In recent years, disasters such as tsunamis and floods have occurred frequently due to sea level rise, climate change or other natural and man-made reasons, posing a greater threat to coastal areas such as coasts, docks and ports; inland river basins, lakes, Due to heavy rains and floods caused by the arrival of the rainy season, the surrounding area of ​​the reservoir often overflows and floods farmland and villages, which seriously threatens the safety of people's lives and property. In view of the above problems, it is imperative to choose a reasonable and feasible water retaining structure. In addition, if problems such as heavy rain and water inrush are encountered during the construction process, or when working in the ...

AI Technical Summary

Problems solved by technology

However, some of the filling materials of the existing geotechnical filling bags use soil or sand, which causes the installation and disassembly of the water retaining facilities to be time-consuming and laborious, and is not conducive to the reuse of materials; some use water as the filling material. , but it is only applicable to the case of shallow water level, there is a risk of insufficient stability in the case of only one side of the water retaining and the water level is high; there are also water retaining structures such as rubber dams, by connecting the bottom of the filling bag with the surface of the foundation The way of anchoring improves the water-retaining capacity of the overall structure. There are two types of anchoring: unilateral anchoring and double-sided anchoring. Although this method has a certain improvement in stability, it needs to carry out foundation construction in advance and requires a certain construction time. and conditions, and has high requirements on the tensile performance of the local area of ​​the geotextile bag, it is not suitable for the construction of temporary water retaining dams
