Diaphragm wall structure and ecological seepage controlling and bed fixing system

Abstract

The invention discloses an ecological seepage controlling and bed fixing system and a diaphragm wall structure. The diaphragm wall structure comprises an underground seepage intercepting structure andan exposed wall structure. The underground seepage intercepting structure is inserted into the side slope of a riverway in the width direction of the riverway, and therefore a riverbed is stabilizedand prevented from being undercut. The underground seepage intercepting structure comprises a plurality of seepage intercepting parts, the ends, away from the water surface of the riverway, of the seepage intercepting parts are formed on an impervious layer or a bed rock layer of the riverway, the seepage intercepting parts extend to the normal water level height of the riverway in the water levelrising direction, the measure of laying facilities on the impervious layer along the riverway is avoided, and it is avoided that due to the fact that impermeable material need to be additionally arranged, the base body of the riverway or the original ecological environment is damaged. The exposed wall structure is connected with the end, close to the water surface of the riverway, of the underground seepage intercepting structure, and the exposed wall structure is exposed out of the normal water level of the riverway in the water level rising direction. The vegetation development need of a riverside zone is met, and certain landscape water bodies are built.

Description

technical field [0001] The invention relates to the technical field of river channel protection, in particular to an anti-seepage wall structure and an ecological seepage control and solidification bed system. Background technique [0002] In the construction of steep river courses, due to the serious undercutting of the river, in order to stabilize the river bed and increase the longitudinal stability of the river, it is often necessary to build a bed-fixing structure. The traditional bed fixers are mainly concrete stone beams, which are mainly used for river bed reinforcement to prevent the river from being cut down, so as to play the role of soil stabilization and sand protection. At the same time, in order to ensure the anti-seepage of rivers, it is often necessary to lay a layer of anti-seepage materials above the river bed, such as concrete bottom protection, geomembrane anti-seepage, clay blanket and other anti-seepage materials.

Problems solved by technology

However, the above-mentioned fixed bed structure is generally laid on the shallow layer or surface of the river bed. Because its structure is permeable, it does not have the function of water retention and seepage control, and has no function of increasing the groundwater level.

The installation of anti-seepage materials will also hinder the connection and material exchange between the river water body and the substrate, thereby blocking the vertical connectivity of the river bed and causing the degradation of the river habitat.
