Embodiment 2

[0044] See 1 to Figure 4 , the embodiment of the present invention discloses an ecological slope protection suitable for a rain source type river course, including several slope protection blocks as described in Embodiment 1, and several slope protection blocks are spliced ​​to form a slope protection block layer, wherein several block bases 1 is spliced ​​to form the lower slope protection of the slope protection block layer, and several block skeletons 2 are spliced ​​to form the upper frame grid 7 of the slope protection block layer, and the upper frame grid 7 is filled with planting soil 9 for planting plants 10 . The lower layer of the block is a full-paved slope protection formed by the block base 1. The ratio of the holes 4 is small and can resist the erosion of a large flow velocity. When the river channel discharges the design flood, the flow velocity is large, but the duration is short, and the upper slope will suffer for a short time. High-intensity scouring and er...

Embodiment 3

[0053] The embodiment of the present invention discloses a construction method for ecological slope protection suitable for rain source type river courses. A number of slope protection blocks as described in Embodiment 1 are prefabricated in the factory, and the construction includes the following steps:

[0054] Step 1: Clean up the weeds on the slope, and excavate to the bottom elevation of the gravel cushion layer 11 according to the requirements of the design drawings;

[0055] Step 2: Clean up the river bottom to the designed height of 15, and install pine piles to fix the feet 13;

[0056] Step 3: leveling and compacting the slope, laying geotextile 12 and gravel cushion 11, and leveling;

[0057] Step 4: Transport the ecological blocks to the construction site, stack them scattered along the line according to the construction needs, and hoist the construction by a crawler crane. The adjacent blocks should be locked to form a slope protection block layer. Among them, sev...

Abstract

The invention relates to a slope protection building block, an ecological slope protection suitable for a rain source type river channel and a construction method thereof. The slope protection building block comprises a building block base, clamping heads or / and clamping grooves are arranged on all the side faces of the building block base, a building block framework is arranged on the upper end face of the building block base, and the ecological slope protection comprises a plurality of slope protection building blocks; the plurality of slope protection building blocks are spliced to form a slope protection building block layer, a plurality of building block bases are spliced to form a lower-layer slope protection of the slope protection building block layer, a plurality of building block frameworks are spliced to form an upper-layer frame grid of the slope protection building block layer, and the upper-layer frame grid is filled with planting soil for planting plants. According to the slope protection building block, the ecological slope protection suitable for a rain source type river channel and the construction method thereof, the problem that flood control safety and the ecological landscape function cannot be both considered in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and in particular relates to a slope protection block, an ecological slope protection suitable for a rain source type river course and a construction method thereof. Background technique [0002] The runoff of rain-source rivers mainly comes from rainfall, and the recharge on the surface and underground is very small. When there is rain, the runoff will be produced, and the flow will basically stop if there is no rain. The annual precipitation is mostly concentrated in summer and autumn, and the precipitation in each season is extremely uneven. The area of ​​the river basin is small, resulting in short confluence time, large river gradient, steep flood rise and fall in the flood season, very little water in the dry season, and even the river bed dries up. [0003] The designed flood peak flow of rain source type rivers is often very large, and generally there ...
