Abstract

The utility model discloses an upright retaining wall type ecological slope protection. The slope protection comprises a concrete block layer, a rockfill layer and a sandstone layer which are arranged sequentially from a river course into the soil of a reinforcing dam, and through-holes are formed in the concrete block layer. The utility model has the advantages of firm structure and ecological repair.

Description

Vertical retaining-wall formula ecological revetment

Technical field

The utility model relates to the city river of carrying and the guard technology of bridge both sides dykes and dams, is specifically related to a kind of vertical retaining-wall formula ecological revetment.

Background technology

Owing to be subjected to the restriction of execution conditions, the most common slope protecting technique that adopts in vertical retaining-wall bank protections such as city river, bridge both sides dykes and dams at present mainly contains: the gabion net, grout bank protections such as stone, dry stone wall building block.But, no matter be any technology, all there are weak points such as the insecure or non-ecological property of some structures, wherein:

1) may there be fracture in use for some time in the establishment net of gabion net bank protection employing, thereby makes the stone landing, the problem that bank protection collapses, and also the gabion net is from existing the aesthetic property defect of insufficient in appearance.

2) grout this hard structure bank protection of stone, cut off the water body exchange and the circulation in the interior soil body of bank protection and river, stoped the aqueous vapor circulation of river course and riverside vegetation, reduced the self-purification capacity of river.

3) dry stone pitching often exists firm degree not enough owing to lack reinforcement measure, is collapsed by torrential wash easily.

The utility model content

The utility model provides a kind of sound construction, has repaired ecological vertical retaining-wall formula ecological revetment in order to overcome the deficiency that above prior art exists.

The purpose of this utility model realizes by following technical scheme: this vertical retaining-wall formula ecological revetment, it is characterized in that: the concrete block layer that soil is arranged in order in comprising from the river course toward bank protection, crushed stone layer and sand stone layer, described concrete block layer is provided with through hole.(each layer thickness is specifically decided according to factors such as river course sluicing intensity, water volume flow rate and ground loading loads, and sluicing is excessive can consider to adopt the reinforced concrete segment layer to replace the concrete block layer with the big river course of ground loading)

Described crushed stone layer comprises several layers small crushed stone piece layer and the big crushed stone layer of several layers.

Described crushed stone layer comprises 1 layer of small crushed stone piece layer and 1 layer big crushed stone layer, and small crushed stone piece layer and sand stone layer are adjacent, and big crushed stone layer is adjacent with the concrete block layer.

Described concrete block layer is piled up by a plurality of building blocks unit and is constituted, the building block unit be shaped as cuboid, length is 35～45cm, thickness and width are 10～20cm, connect by cementing between the building block unit.(the building block unit can make in advance, and size is determined on a case-by-case basis, and for make, transport and construction etc. makes things convenient for, general length is about 40cm, and thickness and width are advisable about 15cm.)

The big or small visual river of described concrete block layer through hole wash away with water in concrete condition such as concentration of suspension do suitably to adjust, the area maximum of through hole is no more than 1/3 of concrete block layer.

Described through hole be shaped as circle, ellipse, rhombus, triangle or trapezoidal.

The utility model has following advantage with respect to prior art:

One, this vertical retaining-wall formula ecological revetment, because skin is the concrete block layer, in crushed stone layer and sand stone layer are arranged, intensity is big, not fragile, durable in use, antiscour intensity and ground loading ability are enough big, and this programme has solved in the bank protection and exchange of the water body in river and the problem that circulates, the water of water can filter in the soil that enters in the bank protection through crushed stone layer and sand stone layer by the through hole on the concrete block layer in the river course, in the river course water yield hour, the water in the bank protection soil horizon also can see through sand stone layer, through the crushed stone layer, through hole on the concrete block layer enters the river course, so that river course water is carried out supply, reach the purpose of water exchange.In addition, crushed stone layer and sand stone layer can form the water of flowing through and filter self purification, and crushed stone layer and sand stone layer also can slowly be grown some microorganisms, and the river that enters soil is also had biological purification.

Two, the through hole of concrete block layer can be cast into various forms as required, when the little and concrete block of dry season and the water yield surfaces, can play the effect of beautifying scenery.

Three, the crushed stone layer adopts the classification of small crushed stone piece layer and big crushed stone layer to lay, and when river course and bank protection soil carried out the water exchange, the soil of bank protection and sand stone layer can not enter the river course because of washing away.

Description of drawings

Fig. 1 is the whole structure figure after a kind of vertical retaining-wall formula of the utility model ecological revetment is laid.

Fig. 2 and Fig. 3 are front view and the sectional drawings for the building block unit of concrete block layer.

Number in the figure is: 1 is sand stone layer, and 2 is small crushed stone piece layer, and 3 is big crushed stone layer, and 4 is the concrete block layer, and 5 is soil in the bank protection, and 6 is the river course, and 7 is the rhombus through hole, and 8 is manhole.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

A kind of vertical retaining-wall formula ecological revetment as shown in Figure 1, comprise from river course 6 toward bank protection in the concrete block layer 4 that is arranged in order of soil 5, big crushed stone layer 3, small crushed stone piece layer 2 and sand stone layer 1, concrete block layer 4 is provided with through hole.(each layer thickness is specifically decided according to factors such as river course sluicing intensity, water volume flow rate and ground loading loads, and sluicing is excessive can consider to adopt the reinforced concrete segment layer to replace the concrete block layer with the big river course of ground loading)

As shown in Figures 2 and 3, concrete block layer 4 is piled up by a plurality of building blocks unit and is constituted, the building block unit be shaped as cuboid, length is 40cm, thickness and width are 15cm, connect by cementing between the building block unit.(the building block unit can make in advance, and size is determined on a case-by-case basis, and for make, transport and construction etc. makes things convenient for, general length is about 40cm, and thickness and width are advisable about 15cm.)

The big or small visual river of concrete block layer through hole wash away with water in concrete condition such as concentration of suspension do suitably to adjust, the area maximum of through hole is no more than 1/3 of concrete block layer, 2 rhombus through holes 7 in the middle of present embodiment has comprised and 4 manholes 8 at four angles.

The above-mentioned specific embodiment is a preferred embodiment of the present utility model; can not limit claim of the present utility model; other any change that does not deviate from the technical solution of the utility model and made or other equivalent substitute mode are included within the protection domain of the present utility model.
