Description
Technical field
The present invention relates to a kind of slope earth-retaining wall and construction method thereof, particularly relate to one and be applicable to gradient slope, embankment location or road
Moat steep slope region props up retaining wall and the construction method thereof of gear.
Background technology
Retaining structure, the version such as including retaining wall, antiskid (anchoring) stake, anchor cable (bar), it is used to support, reinforce
Banket or slope soil, prevent from collapsing sliding to keep its stable a kind of building.Retaining wall is a gear the most frequently used in engineering construction
Works, is mainly used in supporting embankment filled soil or slope soil, prevents from banketing or soil deformation unstability, bear the lateral soil pressure of the soil body
Power, its purposes specifically includes that (1) reduces execavated rockmass height, reduces excavation quantity, it is to avoid natural slope failure slump；(2) receive
Contracting embankment toe, reduces fill yard and floor space, it is ensured that roadbed reclamation；(3) avoid roadbed along river to squeeze contracting riverbed, prevent
Current scour roadbed.
For gradient slope, embankment location or cutting steep slope region etc., side slope is high and precipitous, the shallow-layer soil body be difficult to domatic fixing or
Owing to large area excavation ground destroys the original balance of massif, needing, retaining structure is set and prevents slope soil or cunning of collapsing of banketing, mesh
Before conventional have gravity retaining wall.Gravity retaining wall maintains retaining wall under soil lateral pressure effect with the deadweight of wall body
Stable, wall body is from great so that produces bigger frictional force at the bottom of wall with basic earth, thus balances wall back of the body active earth pressure.Gravity
Multiplex sheet (block) barnacle that grouts of formula retaining wall is built, and lacking building stones area sometimes can be with concrete precast block as masonry, or directly
With concreting, typically it is unworthy of reinforcing bar or only configures a small amount of reinforcing bar at subrange.This barricade form is simple, easy construction,
Can gather materials on the spot, applied widely.But in engineering practice, gravity retaining wall there is also problems with: (1) gravity type is kept off
During cob wall construction, the first excavation slope soil body the most from top to bottom, then masonry panel or pour walls concrete from the bottom up, when body of wall relatively
Gao Shi, whole excavated surface is big and steep, to original slope soil produce strong unloading disturbance, slope collapsing slide when being easily caused construction,
Especially more prominent in heavy cut location；(2) gravity retaining wall relies on self gravitation to maintain balance and stability, therefore from great,
High to ground requirement for bearing capacity, earthen foundation is built the restriction suffering from bearing capacity；(3), when barricade is higher, wall body cuts
Volume is big, and bricklaying quantity is big, uneconomical.
Summary of the invention
First goal of the invention of the present invention is to provide a kind of fin-plate type retaining wall, and this fin-plate type retaining wall is applicable to gradient slope, embankment
Location or a gear of cutting steep slope region, little to soil disturbance during construction, low to ground requirement for bearing capacity, construct low cost, easily
In popularization.
The present invention realizes its first goal of the invention and be employed technical scheme comprise that, a kind of fin-plate type retaining wall, including basis, basis
On shingle nail and spilled water hole on shingle nail, it is structurally characterized in that: described shingle nail face soil face equally spaced be consolidated with vertical
Floor, the shingle nail between floor faces soil face position and is provided with loaded filter.
Compared with prior art, the fin-plate type retaining wall of the present invention provides the benefit that:
When floor space is bigger, after wall, the plane of fracture of the soil body is positioned in the soil between adjacent floor, floor stretch into the plane of fracture after stablize
In the soil body.The frictional resistance stablizing between soil body inner rib plate sidewall and the soil body is utilized jointly to bear soil body side with shingle nail and floor deadweight
To soil pressure, it is achieved slope soil to be propped up gear.Only the lateral soil pressure of the soil body is born by body of wall deadweight than existing Gravity Retaining Wall
Power, its gear effect is remarkably reinforced.
When fin-plate type floor space is less, intercostal soil is by floor side friction power effect, and mobile formation is overall native together with floor
Wall, the plane of fracture is positioned at after floor end in the soil body.The overall cob wall being made up of shingle nail, floor and the intercostal soil body bears wall jointly
The soil pressure that the rear soil body produces, it is achieved slope soil props up gear, only bears soil by body of wall deadweight than existing Gravity Retaining Wall
Body soil lateral pressure, its gear effect is remarkably reinforced especially.
In a word, than gravity retaining wall, a gear effect for fin-plate type retaining wall of the present invention is remarkably reinforced, and total body concrete
Consumption is reduced, and bricklaying quantity is few, lightweight, low to ground requirement for bearing capacity, constructs low cost, it is easy to promote.
When engineering-environment is not suitable for cast in situs, it is possible to use prefabricated components to carry out assembling construction so that the scope of application of the present invention
Extensively, also it is beneficial to it promote the use of.
Second goal of the invention of the present invention is to provide the construction method of a kind of above-mentioned fin-plate type retaining wall, this kind of method can quickly,
Construct out above-mentioned fin-plate type retaining wall easily, and little to soil disturbance during construction, construct the fin-plate type retaining wall obtained
With being firmly combined with of side slope, a gear is effective.
The present invention realizes its second goal of the invention and be employed technical scheme comprise that, the construction method of a kind of above-mentioned fin-plate type retaining wall,
The steps include:
A. in slope soil, excavate the vertical slot mated with floor；
B. colligation floor reinforcing bar the connection reinforcing bar of reserved connection wall panel in the vertical slot of a step, pour coagulation subsequently in vertical slot
Soil is formed and exposes the floor connecting reinforcing bar；
C. excavation shingle nail foundation trench, builds basis by laying bricks or stones；
D. on the basis of, colligation shingle nail reinforcing bar, and make shingle nail reinforcing bar and be connected bar connecting, then set up shingle nail template,
And pre-buried spilled water hole pipe, finally casting concrete in shingle nail template, after concrete setting, remove shingle nail template, formed
Shingle nail；
E. the shingle nail between floor faces soil face position laying loaded filter, backfills the soil body subsequently and tamp between loaded filter and side slope,
Until wall top.
Compared with prior art, the construction method of fin-plate type retaining wall of the present invention provides the benefit that:
During construction, be vertically spaced, at slope soil, the groove that only excavation is adaptive with floor, make use of slope soil from steady characteristic,
Limits decreases earth excavation workload, on the one hand can guarantee that vertical slot is stable, reduces gib quantities, it is often more important that
Decrease the construction disturbance to original slope body, improve working security, also ensure that the stability of slope soil and good propping up
Protect effect.
The present invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
