Abstract

The utility model relates to a river bank concrete block which can be adopted to build channel revetment (protection foundation). The utility model can meet in particular the requirements of rural river ecological construction and landscape construction, and is also suitable for garden water ecological landscape construction. The utility model provides a thin wall concrete block with a hollow cavity, wherein, the inside of the hollow cavity is provided with an annular reinforcing rib; both sides of a faceplate are in the shape of a concave gap. According to the practical height of a river bank project, the utility model adopts full-section integrated design, wherein, only one row of concrete blocks are parallelly arranged on the top of a base slab; underwater holes are formed on an upstream slope and are communicated with the cavities of the concrete blocks to form a long corridor similar to an underwater labyrinth.

Description

Riverbank concrete building block

1, technical field:

The utility model is the concrete building block of a kind of riverbank, adopts the utility model riverbank concrete building block can construct channel revetment (protecting base) engineering, especially can satisfy the requirement of rural area river channel ecology construction and landscape construction, also is applicable to the aquatic attitude landscape construction in gardens.

2, background technology:

At present; common channel revetment engineering is to adopt the method for stone-laying or Cast-in-place concrete to form retaining wall; although it is in the behavior of constraint water; the engineering effect has been brought into play in the aspect that prevents erosion; but; engineering construction is bigger to the influence of environment, and has deficiency aspect the aquatic animals and plants such as protection fish shellfish.

(1) traditional retaining wall bank protection work, be designed to the riverbank section of uniform entity, the water surface and land are cut apart fully, destroyed the living environment that is grown near the fish and shellfish biology of water surface curve to a certain extent, therefore ecological environment has suffered destruction.

(2) traditional bank protection work is because the on-the-spot floor space of stacking of constructional materials is bigger, and therefore, engineering construction is big to the eco-environmental impact of river course bank; Simultaneously, many owing to the construction technology link, comparatively complicated, therefore, the cycle of engineering construction is also longer relatively, and the difficulty of quality control is also bigger.

(3) especially for area, the region of rivers and lakes, Plain, gather in the network of waterways, and the wide line length amount of riparian works is big, adopts traditional channel revetment form, and engineering construction investment is relatively large.

3, summary of the invention:

In order to overcome existing waterway stone-laying, the concrete bank protection work influence to view and environment, the utility model provides a kind of thin-walled concrete pour that has cavity, and with annular ribs, the panel both sides are concave indentation in the cavity of building block; Height according to actual riparian works needs, full section global design, rise above only row's building block from sole plate, be arranged in parallel, upstream face forms hole under water, connect with the building block cavity, form the same gallery space, labyrinth under water, the hydrospace of perching, multiplying is provided for the fish and shellfish aquatic organism.Simultaneously, also merged the water surface and bank land relation, satisfied the hydrophilic vegeto-animal growth needs of requirement and riverbank of people.And prefabricated concrete building block helps batch production production, improves workmanship, shortens the construction period, reduces engineering cost, is particularly suitable for lacking the little river engineering in dense waterway net region rural area, Plain of building stones resource.

The technical scheme that its technical problem that solves the utility model adopts is: with annular ribs, the panel both sides are concave indentation in (1) a kind of thin-walled concrete pour that has cavity, the cavity of building block; (2) according to the height of actual riparian works needs, full section global design is risen above only row's building block from sole plate, is arranged in parallel, and upstream face forms hole under water, connects with the building block cavity, forms the same gallery space, labyrinth under water,

The utility model technology beneficial effect is: the requirement that satisfy the river course bank stability, prevents erosion, and the water front flexible arrangement, the lines flow smoothly; Batch production production is taked in the concrete building block, and quality is controlled easily, on-the-spot simple installation, and cheap, engineering construction is little to eco-environmental impact; Simultaneously, for the fish and shellfish aquatic organism provides the hydrospace of perching, multiplying, help the water ecological environment protection.

Fig. 7 is the channel revetment engineering design of section example that adopts the utility model to construct

Among the above-mentioned figure, 1 is the building block of the utility model concrete; 2 is the ribs in the cavity; 3 is cavity; 4 is the river water level in the application example; 5 is the riverbed, river course in the application example; 6 is the excavation line in the application example; 7 is the key-wall in the application example; 8 is the sole plate in the application example; 9 is geotextiles behind the wall in the application example; 10 is the backfill in the application example; 11 is the greening in the application example.

5, the specific embodiment:

(1) the riverbank concrete building block mode of production: make mould according to the shape of riverbank concrete building block earlier, can be divided into internal mold and external mold, precasting yard preparation microlith C25 concrete, water smash the concussion closely knit after, the part internal mold can be removed immediately, external mold waits for that concrete strength reaches dismounting again more than 70%, can form the riverbank concrete building block shown in the accompanying drawing 1 after the concrete maintenance.2 is the interior ribs of cavity in the accompanying

drawing

2, and 3 is cavity.The concrete building block highly is 100 centimetres (bottom surface is to vertical distances on building block top), and wall thickness is 7 centimetres, and length is 60 centimetres.

(2) the river course ordinary water level sees in the accompanying drawing 74 in this example, and the riverbed, river course sees in the accompanying drawing 75.Determine 100 centimetres of bank protection work design heights according to river water level and riverbed situation, use the utility model riverbank concrete building block, arrange along the river course direction.(1 is the building block of the utility model concrete among Fig. 7)

(3) cut slope excavation (see in the accompanying drawing 7 6), carry out the basic earthwork excavation again after, adopt cast-in-place key-wall of C20 concrete (see in the accompanying drawing 7 7) and sole plate (see in the accompanying drawing 7 8), concrete reaches the next process of constructing again after the intensity.

(4) bottom uses the M100 mortar to build precast concrete block by laying bricks or stones, closely arranges between the building block, covers geotextiles (see in the accompanying drawing 7 9) after the building block, backfill behind the wall, compaction in layers (see in the accompanying drawing 7 10).

(5) the strong kind of happiness water-based is selected in wall top plantation greening (see in the accompanying drawing 7 11), as: mixed plantings such as yellow flag, canna.
