Problems solved by technology

The first way is that due to the activities of bottom fish and the impact of wind and waves, the pool ridge is easy to collapse
The second method, because the connection between the cement boards is easy to fall off, the impact and erosion of the pool water for a long time will form a cavity under the board and collapse, and due to the curing effect of the cement board, it is not conducive to the self-purification of the water quality of the pool water, and the investment is also large.
The third way is because of the wall-type building, the slope is steep, it is easy to collapse, and it is not conducive to operation. The self-purification effect of the water quality is also very poor, and the investment is also very large.
The fourth method has the best slope protection effect, the most durable, but the largest investment

Embodiment 1

[0023] 1. For the old fish pond, first drain the water in the fish pond. This step can be avoided for new fish ponds. After the fish pond slope protection 2 is completely dry, build the fish pond slope protection 2 according to the height: the length of the bottom is equal to 1:1;

[0024] 2. Construct a 370×370mm rectangular footing 4 with cement concrete at the bottom of the fish pond slope protection 2;

[0025] 3. Lay mesh fiberglass geogrid 3 along fish pond slope protection 2, bury mesh fiberglass geogrid 3 by 40cm by footing 4, and spread mesh fiberglass geogrid 3 to the top of the pool ridge 30cm on the upper part , and compacted with capping concrete 1;

[0026] 4. Spread 1cm of floating soil on the laid mesh fiberglass geogrid 3 and compact it with small force;

[0027] 5. Plant ryegrass on the paved interface. After natural maturity, cut off the ryegrass on the surface of the surface. The ryegrass can only be planted for one season;

[0028] 6. After cutting o...

Embodiment 2

[0030] 1. For the old fish pond, first drain the water in the fish pond. This step can be avoided for the new fish pond. After the fish pond slope protection 2 is completely dry, build the fish pond slope protection 2 according to the height: the length of the bottom edge is equal to 1:1.25;

[0031] 2. Construct a 370×370mm rectangular footing 4 with cement concrete at the bottom of the fish pond slope protection 2;

[0032] 3. Lay the mesh fiberglass geogrid 3 along the fish pond slope protection 2, press the mesh fiberglass geogrid 3 with the bottom concrete slab 5 against the footing 4, and lay the mesh fiberglass geogrid 3 on the fish pond slope protection The top of the mesh fiberglass geogrid 3 is pressed close to the top-pressed concrete 1 with a concrete slope protection plate 6;

[0033] 4. Sprinkle 0.8cm floating soil on the laid mesh fiberglass geogrid 3, and compact it with small force;

[0034] 5. Plant three-edged grass on the laid interface. After it matures n...

Embodiment 3

[0037] 1. For the old fish pond, first drain the water in the fish pond. This step can be avoided for new fish ponds. After the fish pond slope protection 2 is completely dry, build the fish pond slope protection 2 according to the height: the length of the bottom edge is equal to 1:1.5;

[0038] 2. Construct a 370×370mm rectangular footing 4 with cement concrete at the bottom of the fish pond slope protection 2;

[0039] 3. Lay mesh fiberglass geogrid 3 along the fish pond slope protection 2, bury mesh fiberglass geogrid 3 30cm below the footing 4, and spread mesh fiberglass geogrid 3 to the top of the pool ridge 20cm on the upper part , and compacted with capping concrete 1;

[0040] 4. Sprinkle 0.5cm floating soil on the laid mesh fiberglass geogrid 3, and compact it with small force;

[0041] 5. Plant barley on the paved interface. After natural maturity, cut off the barley on the surface of the surface. The barley can only be planted for one season;

Abstract

The invention provides a method for building a fishpond protecting slope. The method comprises the following specific steps of: (1) building the fishpond protecting slope according to the ratio of height to bottom length, i.e., 1:(1-1.5); (2) making 370*370 mm rectangular feet by using concrete at the bottom of the fishpond protecting slope; (3) laying reticular glass fiber geogrids along the fishpond protecting slope, and burying 30-40 cm reticular glass fiber geogrids below the foot part, laying the reticular glass fiber geogrids to 20-30 cm at the top end of a pond ridge at the upper part,and compacting the geogrids by using compression concrete; (4) spreading 0.5-1 cm floating soil on the laid reticular glass fiber geogrids, and compacting the floating soil with small force; (5) planting herbaceous plants with prosperous root systems on the laid interface, and cutting surface plants along with the interface after the herbaceous plants grow mature naturally; and (6) after the surface plants are cut, introducing water into the fishpond normally to perform aquaculture production. Through the method, the collapse problem of the fishpond ridge in China is solved, the service life of the fishpond is prolonged, the production efficiency is increased, and the ecological environment of the original pond is maintained.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for building fishpond slope protection. Background technique [0002] Existing fish pond slope protection mainly contains the following methods: 1. natural pond slope fish pond soil natural slope; 2. cement board slope protection is covered with cement prefabricated panels along the natural slope; 3. brick-concrete slope protection is built into straight walls or slopes with bricks The wall can achieve the purpose of slope protection; 4. The concrete cast-in-place slope protection should be compacted on the original fish pond slope for concrete pouring. In the first way, due to the activities of bottom fish and the impact of wind and waves, the pool bank is easy to collapse. The second method, because the connection between the cement boards is easy to fall off, the impact and erosion of the pool water for a long time will form a cavity under the boards and collapse, and due ...
