Description
Technical field
The present invention relates to a kind of rib stake formula peg board retaining wall and construction method thereof.
Background technology
Retaining structure, the version such as including retaining wall, antiskid (anchoring) stake, anchor cable (bar), it is used to support, reinforce and fill out
Soil 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
Structure, 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 reduction execavated rockmass height, reduces excavation quantity, it is to avoid natural slope failure slump；Shrink embankment slope
Foot, reduces fill yard and floor space, it is ensured that roadbed reclamation；Avoid roadbed along river to squeeze contracting riverbed, prevent current scour roadbed.
For Steep Slope Embankment location, side slope is high and precipitous, and embankment fill material is difficult in slope stability, needs first to arrange a gear knot
Structure is the most filling roadbed, and current stake plate type retaining wall is a gear pattern conventional during Steep Slope Embankment fills.
Free arm formula peg board retaining wall is by the pile body anchoring section being anchored in ground, the pile body cantilever segment basseted
And be placed between adjacent pile body cantilever segment and be positioned at the breast boards composition inside stake.The height of pile body free arm section can reach
To about 15m, but after free arm section is highly more than 15m, stake will produce excessive lateral displacement, in some instances it may even be possible to stake can occur
The engineering accident that body fractures.
In order to solve the problems to be solved of the filled height Steep Slope Embankment retaining wall more than 15m, engineering practice occurs
Prestressed anchor pull-type peg board retaining wall.It is between the stable massif inside the stake and stake of above-mentioned cantilevered peg board retaining wall
Horizontal prestress anchorage cable is set, to reduce the lateral displacement of stake so that prestressed anchor pull-type peg board retaining wall is more than ground
Height can reach 20～25m.But in engineering practice, prestressed anchor pull-type peg board retaining wall there is also problems with: pre-
The work progress of stress anchor pull-type peg board retaining wall is complicated, and technical difficulty is high, quality control difficulties；Massif inside stake with stake
Between filling roadbed time, Highway Embankment Compaction and prestressed anchor draw the installation of facility to interfere with each other, easily cause Highway Embankment Compaction degree and anchor
Rope prestressing force is the most up to standard；Prestressed anchor draws the long-term reliability of facility and durability to be difficult to be guaranteed.
Summary of the invention
The first object of the present invention is to provide a kind of rib stake formula peg board retaining wall.This rib stake formula peg board retaining wall is applicable to suddenly
The retaining engineering of slope embankment, have pile body deformation little, gear effective, easy construction, construction costs are relatively low, good endurance
Feature；And the anchorage depth of stake can be reduced, optimize the Cross section Design of stake.
The present invention the technical scheme is that a kind of rib stake formula peg board retaining wall for realizing its first goal of the invention, including
Pile body anchoring section, pile body cantilever segment, breast boards longitudinally disposed between adjacent pile body cantilever segment, it is characterised in that: described
The inner side of pile body cantilever segment is fixing with the floor of horizontally set to be connected.
Compared with prior art, the invention has the beneficial effects as follows:
One, the present invention utilizes being reliably connected between stake and floor, can be effectively improved the bending rigidity of stake, be greatly reduced height
The lateral displacement of stake under cantilever position, the further jib-length of raising stake, and the anchorage depth of stake can be reduced, optimize cutting of stake
Face size.Floor in the present invention can substitute the effect of prestress anchorage cable, and pours together with between floor with stake
Reliable fixing connection, can overcome the defect of the prestressd anchor cable loss become by adulterium, it is ensured that the stability of structure long-term work
And durability.
Two, existing prestressed anchor pull-type peg board retaining wall, it needs to carry out the pore-creating of anchor cable in construction, makes anchor, executes
The anchor of the series of complexes such as anchor, slip casting, construction anchor plate, stretch-draw, sealing off and covering anchorage draws operation, and anchor draws operation and embankment process
Interfering big, difficulty of construction is higher.And floor only need to be hanged with pile body by connection reinforcing bar by the present invention when concreting
Arm section is connected, and can realize the fixing connection of integration of the two, and its work progress is simple, and the construction to embankment is disturbed little,
Integral construction difficulty is lower, and construction quality is high.
In a word, more traditional peg board retaining wall, the deformation of rib stake formula peg board retaining wall of the present invention reduces, work progress letter
Changing, a gear effect strengthens, and the long-term work performance of structure and durability improve.When engineering-environment is not suitable for cast in situs, also
Prefabricated components can be used to carry out assembling construction so that the present invention is applied widely, be also beneficial to it and promote the use of.
The second object of the present invention is to provide the construction method of a kind of above-mentioned rib stake formula peg board retaining wall.The method can be fast
Speed, constructing out above-mentioned rib stake formula peg board retaining wall easily, and during construction, excavated volume is little, few to soil disturbance, a gear is effective.
The present invention realizes its second goal of the invention and be employed technical scheme comprise that, a kind of above-mentioned rib stake formula peg board retaining wall
Construction method, the steps include:
A) excavate the stake holes of pile body anchoring section, the steel reinforcement cage of pile body anchoring section is hung in stake holes, and pour pile body anchoring
The concrete of section；
B) after pile body anchoring section shapes, inside pile body anchoring section, excavate horizontal floor groove, and set up pile body cantilever
The template of section and the template of floor；
C) in the template of pile body cantilever segment and the template of floor, distinguish reinforcing bar and the steel of floor of colligation pile body cantilever segment
Muscle, and connection reinforcing bar is set between pile body cantilever segment and floor；
D) pour the concrete of pile body cantilever segment and the concrete of floor, after reaching curing requirements, remove pile body cantilever segment
Template and the template of floor；
E) between pile body cantilever segment, longitudinally disposed prefabricated breast boards it is layered, until wall top.
Compared with prior art, the construction method of the present invention provides the benefit that:
During construction, only need to excavate the vertical interval trough suitable with floor in slope soil, make use of slope soil
From steady characteristic, decrease earth excavation workload to greatest extent.On the one hand do so can guarantee that vertical slot is stable, reduces interim
Protect quantities；Prior it is the reduction of the construction disturbance to original slope body, improves the safety of construction, also ensure that side slope
The stability of the soil body and good supporting effect.
The present invention is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
