Abstract
The utility model discloses a fish-reef porous concrete prefabricated block that consists of two parts, namely an upper part and a lower part, wherein the figure of the upper part of the prefabricated block has a cuboid structure; a key and a groove that can be engaged with the other prefabricated block are arranged respectively on a pair of side surfaces of the cuboid; the cuboid is provided with holes with communicated top and bottom in longitudinal direction; and four supporting bodies are arranged at the lower part of the prefabricated block and are arranged at four corners on the lower surface of the cuboid respectively. The design of the fish-reef porous concrete prefabricated block sufficiently applies a spatial geometry principle; when masonry blocks are combined, passages used for fish migration can be generated naturally so as to be completely suitable for the inhabitation and reproduction of various biology; and the perfect unification of ecological restoration of riverway and improvement on water quality can be realized.
Description
Technical field
The utility model relates to a kind of concrete precast block, relates in particular to a kind of fish shelter formula porous concrete prefabricated section, is applicable to the ecological revetment of river, lake, reservoir embankment.
Background technology
For a long time, people administer the embankment of surface water bodies such as lake, river and only lay particular emphasis on one-side functional requirements such as flood control, shipping, bank stability, the general hard revetment of Cai Yonging, and river loke shore slope hard revetment has been deprived the living space of green plants and aquatic animal, cut off the material exchange between waters and land-based area, then cause river lake water to give birth to ecosystem breakage, therefore, the ecology construction of hard bank slope has caused the attention of relevant departments.At present, at the 26S Proteasome Structure and Function characteristics on loke shore slope, river, the new configuration that is applicable to inclination bank slope (slope angle is less than 45 °) ecological construction and relevant engineering thereof have been researched and developed.Yet for areas such as the networks of rivers, Plain, the space, river course is is seriously occupied, most bank slopes are all built is the cemented rock shore protection of vertical type, because its mechanical condition and inclination bank slope have than big difference, presses for the new configuration and the material of the ecology transformation of suitable vertical type hard shore protection.
For vertical type river course bank slope, bank face over half and water body produce direct reciprocation, simultaneously this part bank slope also be large-scale aquatic animal such as water fish class perch the procreation space, therefore, require its restoration of the ecosystem carrier under the prerequisite that guarantees enough mechanical strengths, possess similar natural soil water-permeable and air permeable characteristic, and can carry enough space operation places.
The utility model content
The utility model purpose: the purpose of this utility model is to provide the fish shelter formula porous concrete prefabricated section of a kind of suitable vertical type river course bank slope, perches the procreation space for aquatic animals and plants such as fish provide simultaneously with its revetment that builds up.
Technical scheme: fish shelter formula porous concrete prefabricated section described in the utility model, described prefabricated section is made of upper and lower two parts, the appearance profile on the top of described prefabricated section is a rectangular structure, be respectively arranged with on a pair of side of cuboid can be mutually nested with another prefabricated section key and groove, the hole that vertically is provided with up/down perforation of cuboid; The bottom of described prefabricated section is 4 supporters, is separately positioned on the place, four angles of cuboid soffit.
Described hole is cylindrical, is arranged on the center of described cuboid.
More reasonable for the structure that makes prefabricated section, the length of described cuboid and the diameter ratio of described hole are 5: 5: 4: 1.
The utility model is by being provided with key and groove on the rectangular structure of the top of prefabricated section, mutual interlock when making the building block combination does not need connector to fix, the connection of vertical building block simultaneously and fixingly also be connected in series by connector.Ecological slope stability is strengthened in engaged back, and the supporting body structure that relies on its underpart forms the living space of large-scale aquatic animals such as fish naturally, rely on powerful specific area of porous concrete and the indigenous microorganism in the effective enrichment water of pore structure simultaneously, bait as large-scale aquatic animals such as fish, thereby set up stable gauze bio chain, improved the bio-diversity of aquatic ecosystem.
The production method of the prefabricated configuration of porous concrete fish shelter formula building block is according to the building block apparent size, adopts the hard glass steel to make production mould, and the concrete after stirring is filled in the space of mould, adopts surface vibration method vibration 30s, 3min Hou Tuo Mu.Prefabricated configuration adopts the natural conditions maintenance more than 7 days after taking off Mu, promptly can be used for the structure of ecological embankment construction in lake, river and artificial fish nest.
The utility model is to be manufacturing materials with the porous concrete with continuous perforation hole, porous concrete is to be 42.5 Portland cement by label, materials such as the single graded broken stone of 15～25mm, mineral additive, high-performance water reducing agent etc., alkaline slow releasing agent mix by a certain percentage, prepare after stirring, compacting or vibration or the tamping moulding, the hole that self has continuous perforation, porosity is 15～25%, transmission coefficient 1.5～2.5cm/s, compressive strength is 10～25MPa.
The utility model compared with prior art, its beneficial effect is: 1, ecological embankment in the lake, river that makes up based on fish shelter formula porous concrete prefabricated section and artificial fish nest, do not need artificial maintenance, make the mechanical condition of its suitable vertical type ecological revetment by the special construction setting, large-scale aquatic animal activity space can be provided, utilize simultaneously that porous concrete self has than bigger serface, indigenous microorganism in the enrichment water, green plants also can grow therein, be to integrate ecological recovery and water quality strengthened purification, for the enrichment of aquatic animals and plants and microorganism provides the carrier of similar natural soil property bank slope, have bio-diversity effect and purification of water quality effect simultaneously; 2, the porous concrete of the utility model employing is to adopt gathering materials and cementitious material of special grating, porous concrete self has 15～25% porosity, the aperture from micron order to even variation between the millimeter level, thereby, it also is the excellent carrier of indigenous microorganism enrichment in the water, can form the abundant biomembrane of biofacies, utilize the air reaeration of water body, thus strengthened purification water quality; 3, the space geometry principle has fully been used in the design of the utility model fish shelter formula porous concrete prefabricated section, naturally produce passage during the building block combination for fish migration, be fit to the procreation of perching of all types of biologies fully, realized the perfect unity of river channel ecology reparation and water correction; 4, the utility model fish shelter formula porous concrete prefabricated section moulding form is made simple, the production efficiency height, the utility model prefabricated section applied in any combination is flexible, rely on self keyway reinforcing, it is simple and convenient to construct, and saves construction investment, is particularly useful for the structure of artificial fish nest in the ecological construction on vertical type riverbank and the water body, help to set up multifarious biological chain structure in the stable aquatic ecosystem, the ecosystem of repair and reconstruction breakage.
