Abstract

The utility model provides a pond, a water channel or a ditch slope protection, and relates to protection facilities of aquaculture ponds and water inlet and outlet channel slopes. The technical scheme is that the pond or water channel or ditch slope protection comprises hexagonal concrete blocks, a cement sand filtering layer and a nonwoven geotextile, and is characterized in that a bottom beam, a pressing top beam and a middle beam are poured among the slope bottom, the slope top and the middle slope of the pond or the water channel or the ditch through reinforced steel bars; and the bottom beam, the middle beam and the pressing top beam are fixedly connected through edge separating beams by pouring the reinforced steel bar; and the intersection points of the beams above are firmly anchored through reinforcing steel bars; the nonwoven geotextile is paved on the compressed and leveled slope face; and the cement sand filtering layer, which is formed by cement and sand based on the ratio of 1: 9, is paved on the nonwoven geotextile; and the hexagonal concrete blocks are paved on the flat cement sand filtering layer.

Description

A kind of pond or water channel or ditch bank protection

Technical field

The utility model relates to aquaculture pond, the advance escape canal bank protection of (ditch).

Background technology

At present, the bank protection of pond and water channel (ditch) is various informative, mainly contains cement block or cement board jointing paving, cast-in-situ reinforced concrete layer mode, purpose be for protect the pond, the gradient of (ditch) is stable to advance escape canal; Owing to receive restrictions such as the gradient, soil property, bank protection cost, environment for use; This type bank protection has satisfied not aquaculture pond and has advanced escape canal (ditch) to the stable requirement of bank protection; Pond, channel that particularly seepage of water is big, quick ground matter is regional; No matter be cement board jointing bank protection, still cast-in-situ reinforced concrete bank protection all exists the shortcoming that the hidden danger of safeguarding after inconvenient, the soil erosion is discovered difficulty, collapsed in flakes easily, maintenance cost is high.Though the bank protection in nonirrigated farmland bank protection and Jiang Hai, stream has very successful construction method at present,, in culture fishery, be difficult to adopt for fear of involving great expense.How to make the pond bank protection of construction can solve the gradient stable, can reduce construction cost again, be to need the problem that will solve badly.

Summary of the invention

The purpose of the utility model is a kind of protective slope structure that is applicable to pond, water channel or ditch of design, with the pond that solves aquaculture, a domatic protection difficult problem of advancing escape canal (ditch).

The technical scheme of the utility model adopts hexagon concrete piece, cement sand filter water layer, non-woven geotextile; It is characterized in that in the pond or build bottom girder, capping beam and central sill respectively with steel concrete at the sloping end in water channel or ditch, Po Ding, slope; Building contact with steel concrete between bottom girder, central sill, the capping beam connects fixing at a distance from ridge beam; Said each beam crosspoint mutual riveting of reinforcing bar is pluged with molten metal, and non-woven geotextile is laid on compacting leveling domatic, the weight specification of this non-woven geotextile greater than 200 grams/square metre; On non-woven geotextile, laying the husky mixing ratio of cement is the cement sand filter water layer of cement: sand=1:9, and hexagon concrete piece is layered on the smooth cement sand filter water layer.

The utility model is owing to adopted non-woven geotextile to add the protective slope structure of cement sand filter water layer, hexagon concrete piece pressure surface; Non-woven geotextile can prevent effectively that soil property runs off; Can let in the soil water yield more than needed pass through again; Water flows out in cement sand bed and the hexagon concrete piece slit through drainability preferably, avoids soil property to run off and causes bank protection to subside and the excessive bank protection of extruding of interior side pressure; Adopt the concrete piece paving of hexagonal structure; Make the domatic stronger cellular structure of stability that forms; Bottom girder can prevent effectively that the bank protection level from moving outward, and central sill is convenient to produce in pond or the canal (ditch), maintenance operation, and central sill, capping beam can reduce bank protection; Bottom girder, central sill, capping beam, contact can make the stability of bank protection more reliable on the domatic bank protection that is separated into proper area at a distance from ridge beam; Even occur potential safety hazard in the slope, there is not the domatic hexagon concrete piece of jointing, depression or outstanding will appear, be convenient to timely discovery, and convenient for maintaining restores.The bank protection of prior art cast-in-situ reinforced concrete bank protection and cement block jointing paving; Under the situation that soil property runs off in a large number in the slope; The illusion that is supporting in addition in case subside or squeeze badly, will be that large-area bank protection damages; Reparation and sloping inboard backfill be difficulty quite, and the utility model can effectively be avoided these problems.The utility model cost than the lower slightly or similar situation of other form bank protection costs under, it is more stable to have a bank protection, spot failure can in time be found, advantage easy to maintenance.

The specific embodiment

The utility model (referring to accompanying drawing) adopts hexagon concrete piece 4, cement sand filter water layer 5, non-woven geotextile 6; In the pond or the centre on the sloping end in water channel or ditch, Po Ding, slope build bottom girder 1, capping beam 3 and central sill 2 respectively with steel concrete; Building contact with steel concrete between said bottom girder, central sill, the capping beam connects fixing at a distance from ridge beam 8; Each beam crosspoint mutual riveting of reinforcing bar is pluged with molten metal; Non-woven geotextile be laid on compacting leveling domatic 7 on, the weight specification of non-woven geotextile greater than 200 grams/square metre, its amount of lap is not less than 200 millimeters during the non-woven geotextile overlap joint; On non-woven geotextile, laying the husky mixing ratio of cement is the cement sand filter water layer of cement: sand=1:9, and hexagon concrete piece is laid on the smooth cement sand filter water layer.

Claims

1. a pond or water channel or ditch bank protection; Adopt hexagon concrete piece, cement sand filter water layer, non-woven geotextile; It is characterized in that in the pond or build bottom girder, capping beam and central sill respectively with steel concrete at the sloping end in water channel or ditch, Po Ding, slope that build contact with steel concrete between bottom girder, central sill, the capping beam and connect fixingly at a distance from ridge beam, said each beam crosspoint mutual riveting of reinforcing bar is pluged with molten metal; Non-woven geotextile is laid on compacting leveling domatic; The weight specification of this non-woven geotextile greater than 200 grams/square metre, on non-woven geotextile, lay drainability cement sand filter water layer, hexagon concrete piece is layered on the smooth cement sand filter water layer.
