Anti-seepage and anti-impact flood bank for water conservancy project and anti-seepage method thereof

Abstract

The invention belongs to the technical field of flood banks, and discloses an anti-seepage and anti-impact flood bank for a water conservancy project. The anti-seepage and anti-impact flood bank comprises a foundation, base soil, an anti-seepage layer, outer-layer soil and a concrete outer layer; a containing box is fixedly mounted on the water facing surface of the concrete outer layer; an opening is formed in the front surface of the containing box; a top groove is formed in the top of the containing box; water absorption blocks are fixedly installed on the left wall and the right wall of the opening; a water storage tank is fixedly installed at the bottom of an inner cavity of the containing box; and a cooling box is fixedly installed on the water facing face of the concrete outer layer. Water from the interior of the water storage tank is continuously absorbed by the water absorption blocks to continuously wet and cool the inner wall of the containing box, and the situation that due to the fact that the specific heat capacity of water is small, the concrete outer layer and the outer layer of the containing box expand with heat and contract with cold and finally crack caused by the fact that the concrete outer layer and the outer layer of the containing box are exposed to the sun is prevented. Compared to the prior art, the anti-seepage and anti-impact flood bank has the advantage of preventing the concrete outer layer and the containing box from cracking.

Description

technical field [0001] The invention belongs to the technical field of flood control embankments, in particular to an anti-seepage and anti-shock anti-flood embankment for water conservancy projects and an anti-seepage method thereof. Background technique [0002] In water conservancy projects, in order to prevent the flooding of rivers, anti-seepage and impact flood dikes are usually built. The flood dike is a pile of soil, and its outside includes various anti-seepage layers and concrete outer walls to prevent flood impact and water penetration. The piles are long strips, which can stretch for several kilometers along rivers, lakes or oceans, and are a powerful tool to stop floods. [0003] At present, the mainstream design idea of ​​anti-seepage and anti-impact flood embankment for water conservancy projects is to add a built-in anti-seepage layer to the concrete exterior wall and various structures to increase strength, but there are the following problems in the process...

Problems solved by technology

[0003] At present, the mainstream design idea of ​​anti-seepage and anti-impact flood embankment for water conservancy projects is to add a built-in anti-seepage layer to the concrete exterior wall and various structures to increase strength, but there are the following problems in the process of use. The specific heat capacity of the outer layer of the soil (referring to the heat required to raise the temperature of 1kg of homogeneous material by 1K when there is no phase change and chemical change) is very small. It not only aggravates the wear and tear of the outer layer of concrete, but is also prone to cracking, which directly leads to the overall collapse of the flood embankment, which is very dangerous; at the same time, the easily cracked concrete makes the flood embankment directly lose the first line of defense against seepage, resulting in a large number of floods in the future. In the case of buffering and diversion, it directly contacts the anti-seepage layer, which makes the work intensity of the anti-seepage layer rise sharply. In this way, over time, the anti-seepage function of the flood embankment will inevitably be gradually lost; The impact resistance is too passive. On the one hand, the concrete does not divert the flood well enough to withstand the water pressure on the fire embankment itself; With the passage of time, the overall structural strength of the flood levees decreases, making the anti-shock effect less effective
