Embodiment Construction

[0021] Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment:

[0022] Such as Figure 1 to Figure 2 As shown, the preferred embodiment of the present invention discloses a method for overlapping the sudden change of the anti-scourage and bottom protection soft body row, which specifically includes the following steps:

[0023] 1) Production of oblique row bodies on land

[0024] First, according to the scouring characteristics of the anti-scouring bottom protection position, the overlapping angle α between the oblique body 1 and the soft body 2a on the short side is determined. The size of the angle α between them is determined according to the water flow, wind wave and overall river scour characteristics at the bottom protection of the project. The principle is that the more severe the scouring of the embankment, the smaller the angle α.

[0025] Then calculate and determine the length and width of the oblique row ...

Abstract

The invention discloses a lap joint method for a sudden changing part of a scour-preventing bottom-protecting soft mattress. The lap joint method comprises the following steps: 1, manufacturing an inclined tower mattress on land; 2, paving the inclined tower mattress; and 3, paving the soft mattresses at two connected ends. The lap joint method has the advantages that the manufacturing for the lap joint mattress is simple and the construction progress is effectively quickened; the materials are saved and the cost is low; a scouring pit caused by unsmooth water flow at edges resulted from the conventional mattress lap joint is reduced; and the protecting effect for the bottom protector is increased. The lap joint method is suitable for various bottom-protecting projects, such as coastal reclamation and causeway, port breakwater, shipping lane, river channel retaining wall, and the like, and is especially suitable for embankment sections with violent change in beach face in front of the embankment and frequent change in bottom-protecting width.

Description

technical field [0001] The invention belongs to the engineering fields of water conservancy, port, waterway, coast and river revetment, etc., and in particular relates to a method for lapping sudden changes of anti-scour and bottom protection soft row of dikes for land reclamation, port anti-slope dikes, waterways and river revetments, etc. . Background technique [0002] At present, the anti-scour bottom protection methods usually include deflecting flow type, slow flow and silting type, covering protection type, etc.; from the material structure, it can be divided into riprap, firewood row, artificial aquatic plants, soft row, pile column and caisson, etc. . Among them, the covering protection type is to use anti-scouring materials to cover a certain range of scoured areas, such as soft row bottom protection, riprap bottom protection, geotechnical pillows, firewood row, concrete mold bags, etc. all belong to this category. The use of covering protection bottom protection...
