Frame column type frame bank protection structure for city watercourse and construction method of bank protection structure

Abstract

The invention relates to a frame column type frame bank protection structure for a city watercourse and a construction method of the bank protection structure. The bank protection structure comprises a concrete bottom plate, a concrete side wall, a concrete top plate and concrete stand columns, the concrete bottom plate is arranged in the watercourse, the concrete side wall is arranged on the bank slope side of the watercourse, the concrete side wall and the concrete stand columns are cast on the concrete bottom plate, and the concrete top plate is cast at the top of the concrete side wall and the tops of the concrete stand columns. The requirement for foundational bearing capacity is low and the application range of geological conditions is wide. The area of land on the river bank is not reduced, roads on the bank are kept smooth, meanwhile, the riverbed is not deepened, the cross section of passage of the watercourse can be expanded, and hydrophily is enhanced. A cobble facing layer is applied to the expanded riverbed surface in a frame, gaps can provide resting places for fishes, the cobble facing layer not only has the uniform style as a riverbed cobble bottom protecting layer but also is beneficial to growth of bryophyte, and water quality and river bank landscapes are improved.

Description

technical field [0001] The invention relates to a river revetment structure and a construction method thereof for water conservancy projects and municipal engineering, in particular to a frame-column frame revetment structure for urban rivers and a construction method thereof. Background technique [0002] In urban rivers, due to the dense surrounding buildings, the red line for river planning or reconstruction is limited. Generally, a single steep revetment structure or a slope green belt on the upper part, a hydrophilic platform in the middle, and a steeper revetment on the lower part are adopted. Compound section revetment structure. Urban rivers need to meet basic functions such as water storage, drainage, and landscape. The revetment structure is usually relatively simple, and generally has the following structural types: (1) Block stone retaining wall; (2) Concrete retaining wall; (3) Concrete "U" shaped groove. [0003] With the development of society and economy, t...

Problems solved by technology

However, cast-in-situ piles or artificial excavated piles are used as the enclosure structure for this bank revetment structure. Compared with the conventional bank revetment that is directly excavated and backfilled by sloping, the construction progress is slow, the investment is relatively large, and the economy is slightly worse in places where there are no houses and other protected objects.
