Description
Technical field
The present invention relates to a kind of knockdown shore protections.
Background technique
Shore protection is in addition to itself Safety of Flood Control security function at this stage, and the functions such as ecoscape and hydrophilic demand are also increasingly
It is taken seriously.The hydrophilic demand of landscape in order to meet river bank, at present frequently with the form of second level shore protection: level-one shore protection wall top
Absolute altitude reduces, and improves hydrophilic experience；Second level shore protection combination landscape function is arranged after level-one revetment, while second level shore protection wall top
Absolute altitude meets requirement of setting up defences.But various odjective causes are limited, shore protection process of construction often can not synchronous reality with landscape construction engineering
It applies, usually first implements bank-protection works, for Safety of Flood Control needs are met, shore protection is generally first using a wall to the pattern on top, after
After continuous landscape engineering qualified to exploit, then built shore protection is carried out to cut top, creates second level shore protection.Above embodiment causes to give up
It abandons engineering, time-consuming consumptive material, therefore the present invention and designs a kind of combined type shore protection and avoid the above problem.
Summary of the invention
The object of the present invention is to provide a kind of knockdown shore protection, with realize recent shore protection it is simple, rapidly, green construction,
And the recycling of second level shore protection at a specified future date, reduce abandoned project.
To achieve the goals above, technical scheme is as follows: a kind of knockdown shore protection comprising cast-in-place level-one
Shore protection and prefabricated second level shore protection, the level-one shore protection use high-rise pile cap formula structure, and wall is cast-in-situ reinforced concrete structure, by bottom plate
With block earth steps composition, wall top is connected with flower trough mud upper thread, and level-one shore protection bottom sets pile foundation, it is characterised in that the second level shore protection is
Prefabricated assembled shore protection, the second level shore protection are placed on level-one shore protection, are connected by mortar cementitious；The prefabricated second level shore protection
It is formed by several prefabricated shore protection unit splicings, it is connected using being spliced by rebate between two contiguous prefabricated shore protection units, in advance
Shore protection unit processed reserves prestressing force pulling eye, built-in metal bellows in prestressing force pulling eye, prestressing force along shore protection length direction
Rope sequentially passes through the metal bellows of the prefabricated shore protection unit of multistage, and stretch-draw prestressing force rope connects the multiple prefabricated shore protection unit
Cheng Yijie second level shore protection, prestressed cable both ends are anchored using backing plate and nut, set deformation joint between two adjacent sections second level shore protection, institute
State and fill pointing polyethylene low ratio foamed plate in deformation joint, between polyethylene low ratio foamed plate embedding neoprene to sealing, and
It is sealed using one-component polyurethane sealant.
Further, every 2~6 prefabricated shore protection units are a section second level shore protection, prefabricated shield in the prefabricated second level shore protection
The full-length of bank unit is 2.5m, and the both ends setting of prefabricated shore protection unit matches rebate, two contiguous prefabricated shore protection lists

Along the later period when ecoscape Promotion Transformation, innerland range after original prefabricated assembled second level shore protection integral hoisting to wall is incited somebody to action,
It realizes the recycling of second level shore protection, reduces abandoned project.
Under normal conditions, it before construction, needs to carry out planning and designing to the shore protection and riverbed on riverbank.The planning mud face in riverbed
Line, that is, the upper space in riverbed marked on drawing when planning and designing, also known as planning riverbed mud upper thread.It is also required to leaning on
The mud upper thread of bank side carries out planning and designing, to meet requirement of setting up defences.
When land used condition is limited, and the determination and implementation of the landscape engineering scheme after river mouth line lag behind dyke transformation up to standard
Engineering can not disposably be implemented the second level shore protection of dyke in place, when needing to take nearly excess processes at a specified future date, be considered as selecting this
The shore protection of invention.In addition, the bank protection structure pattern that conventional bank section can also be provided using the design.In practical applications, according to reality
Border site condition determines suitable pile foundation length, and then determines other structures size, and it is multiple finally to carry out safety to the design structure
Core is to ensure the safety of structure.
Shore protection of the invention has the advantage that
1, combination two stage assembled shore protection of the invention can match landscape engineering along the river, meet nearly at a specified future date combine and design, account for
Ground area is small, is readily transported and lifts, problem that can be narrow with effective solution construction site, and is able to achieve the weight of second level shore protection
It is multiple to utilize, reduce abandoned project, meet innovation, coordination, green idea of development.
2, second level assembled shore protection of the invention is prefabricated components, reduces cast-in-situ steel reinforced concrete Jie Ju construction period
Length, speed of application are slow, are influenced the problems such as big by season and weather, shorten construction period.
3, quick construction of the present invention is convenient, and the influence to surrounding enviroment is smaller, and noise is small, and fugitive dust problem is small, is conducive to ring
Border protection.
4, flood control water blocking task may be implemented in bank protection structure monolithic stability of the invention.
