Problems solved by technology

Existing freshwater aquaculture pond slope protection mainly adopts forms such as stone slope protection, brick slope protection and plastic film slope protection. Among them, stone and brick slope protection are used, which have a long service life and good slope protection effect, but are expensive and increase the cost of breeding; plastic film The construction cost of slope protection is low, but the plastic film is prone to aging and damage, and its service life is short, so it needs to be replaced within a certain period of time

Embodiment 1

[0014] 1. Pond slope trimming: trim the slope body according to the slope ratio of 1:1.5, and excavate two circles of steps on the slope according to the breeding needs to facilitate production operations. The width of the steps is 30 cm, and the machine is flattened and compacted. A 50 cm deep and 40 cm wide trench was dug around the foot of the ridge, and the excavated soil was placed at the bottom of the pond beside the ditch for use.

[0015] 2. Construction machinery and materials: one 90kw air compressor and one 7.5kw jet machine for construction. When there is no power supply or the power supply is insufficient, a generator is required. One mixer. The materials are selected from cement, yellow sand, and stones (melon seeds, with a particle size of about 0.75 cm) in a ratio of 1:2:3, and are fully mixed with a mixer.

[0016] 3. Shotcrete: Spray the grooves around the foot of the ring ridge first, and complete it at one time. Spray the ridge wall again, and the ridge ...

Abstract

The invention discloses a revetment of a freshwater aquaculture pond and a construction method of the revetment. The construction method includes the steps of pond slope fishing, construction machinery and material preparation, guniting, backfilling, capping and maintaining. A pond revetment building mode which is low in construction cost, long in service life and good in slope protection effect is provided, and the revetment is simple in operation and high in practicability and has remarkable economic and social benefit.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a slope protection and construction method for freshwater aquaculture ponds. Background technique [0002] Pond slope protection is an important part of freshwater aquaculture pond construction, and plays an important role in maintaining the shape of the pond and prolonging the service life of the pond. In the case of no slope protection for the pond, the pond wall is subjected to external forces such as soaking, scouring and wind and waves for a long time, which will easily lead to landslides and other phenomena on the pond wall, resulting in shallow pond depth and reduced breeding capacity, directly reducing pond productivity and increasing Therefore, slope protection is particularly important in the construction of aquaculture ponds. Existing freshwater aquaculture pond slope protection mainly adopts forms such as stone slope protection, brick slope protection...
