Embodiment Construction

[0026] Now in conjunction with the accompanying drawings, this patent is further described, and the main operating points in the construction technology are as follows:

[0027] 4.1. Construct the cofferdam and set up the workbench: set up the foothold at the junction of the river bank slope and the original river surface, the width of the foothold is 1 meter, and draw the foothold control line along the center of the foothold. Determine the center position of the cofferdam according to the position of 5 to 10 meters from the town foot control line, and use amphibious dredgers to build a construction cofferdam along the river on the beach. The side of the cofferdam close to the bank slope is the top stalk, and the junction of the top stalk and the original channel surface is the top stalk control line. Excavate the operation platform along the top stem from the top stem control line.

[0028] 2. Town foot construction

[0029] The construction process of the town foot is: ex...

Abstract

The invention discloses a gabion box ecological gabion river channel slope protection construction method. The gabion box ecological gabion river channel slope protection construction method is mainly characterized in that the defect that only the flood control function, the water diversion function, the drainage function, the impoundment function, the shipping function and the like of a river channel are often considered according to a traditional river channel slope protection structure, and the ecological function of the river channel is rarely considered is overcome. The gabion box ecological gabion river channel slope protection construction method includes the following steps that a cofferdam is constructed, a worktable is arranged, and a footing construction period is carried out; after gabion slope protection construction is over, gaps between surface course dimension stone are recharged with soil and watered, it is ensured that the gaps of dimension stone are filled with soil, and a dimension stone slope is covered by a layer of cultivating and planting soil; aquatic plants are planted underwater, and a lawn is planted on a bank of the river channel. According to a construction technology, water, cement and a formwork are not needed, and construction is convenient. The gaps between building stone can be manually or naturally filled with mud on earth, root systems of the plants can be deeply pricked into the slope through the mud between the building stone, so that engineering measures are combined with vegetation measures, and a soft overall protection face is formed. The requirements for water and soil conservation and environment greening are met, and therefore the original ecological environment is recovered.

Description

technical field [0001] The invention relates to a construction method for slope protection of a gabion ecological gabion river course, which can be applied to bottom protection, slope protection, slope foot, gully and other protection of river courses or embankments, and belongs to the technical fields of water conservancy, hydropower and municipal engineering. Background technique [0002] Traditional river slope protection structures often only consider the flood control, water diversion, drainage, water storage and shipping functions of the river, and seldom consider the ecological functions of the river. Thus destroying the ecological environment of the river course. The ecological purification project of drinking water sources in Yancheng City considers from an ecological point of view, and adopts gabion ecological gabion slope protection on the Python River outside the water intake, on the Zhuligou and in the water level change area of ​​the reservoir area. The gabion...
