Description
Technical field
This utility model relates to a kind of sea water marine sand concrete torsion-bending ratio, it is adaptable to seashore sea wall, seashore highway embankment
Side slope protection and need cut down wave impact force bank protection engineering.
Background technology
18 big reports propose " to improve marine resources development ability, determine to safeguard national marine rights and interests, build ocean strong
State " strategy, exploitation ocean be economic construction, social development, national security, promotion Energy restructuring and the weight of development in science and technology
Big demand.
China's ocean area 3,000,000 square kilometres, island sum reaches more than 5000, coastline total length 3.2 ten thousand kilometers, its
1.8 ten thousand kilometers of coastline, mid-continental, 1.4 ten thousand kilometers of coastline, island, coast protection task is heavy；Wave is to coastal works
Impact, the most unrestrained to cause the situations such as estuary coast Farmland, house, building are submerged be that high intensity develops island and seashore
Propose a series of new challenge.Torsion-bending ratio, as the large-sized artificial xoncrete structure of a kind of uniqueness, utilizes dead weight and block
The unique torsion king's word structure of body plays energy dissipating wave resistance effect, can effectively keep off tide, wave resistance, protection seashore, island, beach, river mouth
Hydraulic structures etc., play important effect in coast protection, for reduce wave to the impact of sea wall with wash away, in a organized way
Stacking torsion-bending ratio be considered as a kind of effective means of defence and be widely adopted.
For coastal and offshore area, after torsion-bending ratio can utilize the raw materials such as the most land sand, stone and fresh water prefabricated
It is placed in around seashore and carries out sea wall coast protection.But, the island in off-lying sea and deep-sea is built, is faced with former material at present
Material long-distance transportation, fresh water and fluvial sand lack a difficult problem.Island offshore distance on China South Sea is farthest more than 1500km, on the East Sea
Island offshores distance farthest be about 530km, if transport the material such as fresh water, fluvial sand from land, or carry out building point
Desalinization, sea sand and coarse aggregate without chloridized, great amount of cost will be expended.
The technical problem that the torsion-bending ratio of prior art exists:
Torsion-bending ratio is generally plain concrete, does not use reinforcing bar, there is not steel bar corrosion problem.But because of undressed sea
In sand clay content height, sea water, chemical substance is complicated, directly utilizes sea water, sea sand production plain concrete, water reducer can be caused extra large
The absorption such as chemical substance or silt in water, makes fresh concrete service behaviour unstable, when sea water, sea sand cost fluctuation relatively
Greatly, the unstability of this service behaviour, may cause constructing, engineering accident time serious, may be caused.
Further, since sea water, sea sand are mainly composed of the villaumites such as sodium chloride, calcium chloride and magnesium chloride, these chlorides
It is the early strength agent of concrete, the setting time of concrete can be shortened, make concrete early solidifying, during the construction of serious curtailment concrete
Between.
Finally, it is due to the existence of villaumite material equally, is equivalent in concrete manually fill the materials such as deicer salts, because of
And the Frost Resistance of concrete can be poor, it is unfavorable for that concrete is on active service steadily in the long term.
Utility model content
Not enough for solving prior art, meet the needs that ocean engineering is built, this utility model provides a kind of and directly uses
Sea water, sea sand produce plain concrete torsion-bending ratio and preparation method thereof.Utilize the present invention can realize utilizing nearby near island
The sea water in region and sea sand, significantly reduce the cost of torsion-bending ratio, make simultaneously sea water seawater coagulation soil have service behaviour not because of
Raw-material difference and the feature that larger fluctuation, Workable, frost resistance and long durability are good occurs, be allowed to have wide
Application prospect and significant economic results in society.
The technical solution of the utility model is to provide a kind of sea water marine sand concrete torsion-bending ratio, from top to bottom by three
Rod member forms, and the respectively first rod member, the second rod member and the 3rd rod member, the first rod member and the 3rd rod member are parallel to each other and with second
Rod member is vertical, and the upper surface at the second rod member and the 3rd rod member sets projection.
Further, described projection is prismatic table shape.
Further, described terrace with edge is truncated rectangular pyramids.
Further, the number of the second rod member and the 3rd rod member upper surface projection is 6-12.
With prior art ratio, this utility model sea water marine sand concrete torsion-bending ratio set convex role mainly from
Lower two aspects embody: 1. owing to the first rod member upper surface is for pouring mouth, being open, it is impossible to arrange projection, this utility model exists
The upper surface of the rod member (the i.e. second rod member and the 3rd rod member) in bottom and intermediate layer increases projection, and fresh concrete can be made in shake
In dynamic forming process by bubble coalescence in terrace with edge projection, bubble after opening, is conducive to discharge at the terrace with edge of mould, from
And improve performance and the outward appearance of torsion-bending ratio goods；2. the projection that the upper surface of the second rod member and the 3rd rod member is arranged is owing to increasing
The surface roughness of torsion-bending ratio, thus increase torsion-bending ratio cleave, the efficiency of the wave that disappears, improve the energy dissipating of torsion-bending ratio
With bank protection ability, the protruding prismatic table shape structure, the particularly projection of truncated rectangular pyramids shape of being preferably can improve torsion-bending ratio further
Energy dissipating and bank protection ability.
