Problems solved by technology

[0003] However, in areas where sandy soil is widely distributed, such as Songhua River and Nen River, due to the lack of stone materials, long-distance transportation of block stones or concrete prefabricated slabs is required during the construction of the above-mentioned slope protection, which greatly increases the investment cost of the project.

Embodiment 1

[0038] refer to figure 1 , is a sandy soil embankment slope protection structure disclosed by the present invention, comprising slope protection 1, cage 2 and sandbags 3, slope protection 1 has been filled before construction, slope protection 1 is trimmed into a ladder shape, and cages are divided into 2 Layers are placed on the ladder, and the upper net cage 2 is pressed and held on the lower net cage 2, and the upper net cage 2 and the lower net cage 2 are staggered and overlapped, and the lap length is 20-30cm, so that the upper and lower net cages 2 are snapped together to increase the integrity of the net cage 2 and the stability of the slope protection 1 structure. Sand bag 3 is filled with sandy soil, is contained in net cage 2, and net cage 2 interior is filled, and sand bag 3 only allows water to see through, does not allow sandy soil to pass through, and sand bag 3 selects specific gravity light, durable Acid-base, corrosion-resistant, high-strength geotextiles to ...

Embodiment 2

[0044] refer to figure 1 with figure 2 , a kind of sandy soil embankment slope protection 1 structure construction method, comprises the following steps:

[0045] S1. After the slope protection 1 is built, the debris on the slope protection 1 is cleaned up, the slope surface of the slope protection 1 is excavated, and repaired into a ladder shape, and the step surface is compacted with compaction equipment;

[0046]S2. Make gabion gabion corner protection 4 at the bottom of slope protection 1. First, level and compact the bottom of slope protection 1 on the water side, put the pre-installed gabion gabion in an appropriate position, and place the gabion gabion along the edge The various parts are connected to form a continuous and unified whole. Stones are filled in the net cage 2, generally the thickness of each layer is controlled at about 25-30cm, and it is properly compacted, and the surface is stacked flat. During the filling process of the gabion, mechanical and manua...

Abstract

The invention relates to a sandy soil embankment revetment structure, and relates to the technical field of water conservancy engineering. The sandy soil embankment revetment structure includes a revetment, net cages arranged on the revetment and sand pockets arranged in the net cages, wherein the net cages are filled with the sand pockets, the net cages are laid on the revetment in a stepped shape, the net cages on the upper layer are pressed and fixed to the net cage on the lower layer, the sand pockets are filled with sandy soil, and the sandy soil cannot penetrate through the sand pockets.At the sandy-soil-enriched areas, the sand pockets are used for protecting the revetment, application and transportation of stone can be reduced, and the sandy soil embankment revetment structure hasthe advantages of low cost, good protective effect and high anti-scouring ability.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a sandy soil embankment slope protection structure and a construction method thereof. Background technique [0002] At present, embankment slope protection generally adopts Renault pad slope protection, lead wire cage slope protection, concrete slab slope protection and dry block stone slope protection, so as to increase the stability of slope protection, prevent river water from scouring and damage slope protection, and increase the anti-scouring capacity of slope protection. [0003] However, in areas where sandy soil is widely distributed, such as Songhua River and Nen River, due to the lack of stone materials, long-distance transportation of block stones or concrete prefabricated slabs is required during the construction of the above-mentioned slope protection, which greatly increases the investment cost of the project. [0004] Therefore, how to adapt to the lo...
