Abstract

The invention discloses a method and equipment for rescuing dike downstream slope water seepage dangerous case by using three-dimensional composite filtering pads. The method comprises the steps of: pre-making the three-dimensional composite filtering pads and connectors like bolts; transporting the three-dimensional composite filtering pads and the connectors to the site after detecting the dangerous case; cleaning the site of the dike downstream slope water seepage dangerous case; placing a plurality of three-dimensional composite filtering pads at a dike downstream slope water seepage place and adding cover weight; and connecting the three-dimensional composite filtering pads which are placed at the dike downstream slope water seepage place into a whole by using the connectors. The used three-dimensional composite filtering pads respectively are composed of three layers of materials and are characterized in that: the upper layer and the lower layer of the three layers of materials are filtering layers; the middle layer is a filter core layer; and the three layers of materials are composited into a whole. According to the invention, by means of a method for changing the earthwork for rescuing the dike downstream slope water seepage dangerous case in flood prevention work into special equipment, the traditional materials are changed into new materials which are batch-produced by utilizing factorization, the three-dimensional composite filtering pads can be paved at the water seepage places in a short time, so that precious time is saved for flood fighting.

Description

technical field [0001] The invention relates to a method and equipment for flood control and emergency rescue in flood seasons, in particular to a method for using a three-dimensional composite filter pad to rush to protect the dangerous situation of water seepage on the backwater slope of an embankment in flood season, and the equipment used in the method. Background technique [0002] Our country's existing dikes are 25×10 4 km, of which the main embankment is 6.57×10 4 km. Due to the limitation of embankment conditions at that time, the current embankment is characterized by poor embankment foundation conditions and embankment filling quality. Under the effect of high water level in flood season, dikes are prone to dangerous situations such as landslides and leaks, which lead to the occurrence and development of dangerous situations of seepage on the back slope of the dike. [0003] The rescue and protection of dangerous water seepage in dams should be based on the pri...
