Description

Fully-prefabricated assembled green retaining wall

Technical field

The utility model relates to the soil-baffling structure component in civil engineering, in particular to a kind of fully-prefabricated assembled green gear Cob wall.

Background technique

Gravity retaining wall structure is simple, and stress is clear, in civil engineering using relatively broad.Currently, gravity type Retaining wall is in the majority with cast-in-place structural, and formwork erection is needed to pour, to construction period height, manual work difficulty, concrete transportation and support Shield difficulty is big to wait areas (such as high and cold, High aititude hard and dangerous mountain area) to cause great inconvenience.Meanwhile as China is to environmental consciousness Continuous enhancing, the plain concrete barricade afforestation effect of large volume is bad, higher cost, it would be highly desirable to improve.

By the current situation of current retaining wall, retaining wall structure needs, which need to have following 4 kinds of functions and just be able to satisfy engineering, to be built If demand, it may be assumed that 1) can prefabricated, structure is preferably complete prefabricated components, concrete amount is reduced or avoided, to shorten work Phase reduces cost, improves construction efficiency；2) fabricated construction, precast construction is divided blocking, and fritter is light-duty, is readily transported, from Transport is easy for construction to on-site consolidation, that is, plastic after prefabrication；3) component connection is simplified, in order to make barrier wall structure system An entirety is formed, needs to connect all parts using connector, connector should use precast construction as far as possible, preferably rely on component Itself special tectonic carries out reducing the number of components and working procedure from locking；4) environmentally protective, traditional road cutting type protecting wall is general Flower bed is artificially shelved in wall top platform or plantation parthenocissus is afforested, and plant type selecting is single, and afforestation effect is bad.Current phase It closes document and shows that domestic and international project personnel have carried out some researchs to the prefabricated of retaining wall, but be provided simultaneously with above-mentioned 4 functions Structure do not occur also.

For example, a kind of a kind of entitled " retaining wall " supporting and retaining system is disclosed in the patent specification of Patent No. JP4711618B2 Structure, the structure use all round closure that surrounds of concrete structure, transparent dado structure, landfill rubble, ovum in structure The materials such as stone form rock-steady structure, and retaining wall is piled up to form retaining wall by grade of side slope layering, which has prefabrication and assembly construction The characteristics of changing construction, but disadvantage is more obvious: and connectionless between earth-retaining wall member, structural integrity is poor, the slope of retaining structure Degree cannot be excessively steep, highly cannot be too high；Retaining wall needs to carry out supporting and retaining system by the self weight of charges, so filler must be broken Stone, cobble etc. should not greatly reduce the scope of application of barricade by the material of current scour to guarantee stable structure, and be difficult into Row greening, landscape effect are poor.

For another example, entitled " retaining wall is disclosed in the patent specification of patent No. US2017/0284052A1 The structure of system method of supporting same, and kit for use in construction same ". The structure carries out assembled molding using prefabricated assembled component, gravity retaining wall scope is not belonging to, by prefabricated section and bottom plate Connection formed be similar to " L-type retaining wall " lightweight construction resist soil pressure, limited by prefabricated block size and bottom plate, the structure Applicable barricade is shorter, and does not have greening function.

A kind of entitled " quick-assembling green plant growth barricade is disclosed in the patent specification of notification number CN105625261B Precast concrete block and system and construction method ".The structure is pin-connected panel retaining wall, has greening function, but basic and prefabricated It is attached between block by cast-in-place constructional column, structure can not be certainly steady, needs by shape between the cast-in-place bottom plate in basis and constructional column At the structure similar to cantilever retaining wall resist soil pressure, prefabricated section is similar to the breast boards of pile slab structure, due to gear Cob wall system by constructional column bear shearing and moment of flexure, influenced by the sectional area of constructional column, barricade cannot be made excessively high, and basis and Connector uses cast-in-place structural, increases construction complexity, limits the duration, improves cost.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of fully-prefabricated assembled green retaining wall, building block structures Part and connecting elements can be prefabricated in the factory production, and assembled at the scene is plastic formation retaining wall, to overcome existing pin-connected panel The basis of retaining wall and connector need to be using the long construction periods that cast-in-place structural is made and inconvenient deficiency of constructing.

It is as follows that the utility model solves technical solution used by above-mentioned technical problem:

The fully-prefabricated assembled green retaining wall of the utility model, retaining wall structure body are spelled by blockwork unit transverse On dress, longitudinal assembled formation and located structure basis, each blockwork has the implant plate forward extended out by foreboard outer wall, It is characterized in that: assembled, the longitudinal assembled contiguous prefabricated building block unit of the transverse direction is by the clamping knot that is set on its two sides side wall Structure connection and formation locking, or connected by vertically arranged prefabricated connector and form locking；It is single in each blockwork Member has vertically communicated internal cavities, after lateral assembly simultaneously in placement in layers element soil, sandy gravel or rubble in each internal cavities Compacting forms filling body, and retaining wall structure body relies on the reformation self-stabilization certainly of each blockwork unit and Qi Nei filling body.

Plantation chamber is formed between the implant plate and blockwork unit foreboard outer wall, the plantation is intracavitary in blockwork list The drain hole to interlink with internal cavities is set on first foreboard, and the covering setting anti-filter on blockwork unit foreboard inner wall Layer.

The beneficial effects of the utility model are mainly reflected in following aspects:

One, contiguous prefabricated building block unit can itself locking, or by the connection locking of prefabricated connector, each component can be Prefabrication production, assembled at the scene is plastic formation retaining wall, realizes that the complete prefabricated and structure of component is assembled entirely, transporter Just, long construction period that the basis and connector for and effectively overcoming existing pin-connected panel retaining wall need to be made using cast-in-place structural and The inconvenient defect of construction；

Two, in placement in layers element soil, sandy gravel or rubble in each internal cavities and shape is compacted after blockwork is laterally assembled At filling body, assembly, which forms retaining wall structure, has a self-stabilization feature, i.e., retaining wall structure body by each blockwork unit and Its interior filling body reforms self-stabilization certainly, and the stabilization of structure or side slope is maintained without any external structure or power, saves About cost；

Three, soil moved in improve the original greening can successively be carried out, the significant increase long-term afforestation effect of retaining wall；

Four, compared with traditional gravity retaining wall, concrete amount 70%~80% can be saved, and without applying mould Plate casting process and concrete curing work, shorten the construction period 80% or more, economic benefit is very significant.
