Description
Technical field
It the utility model is related to a kind of rib stake formula peg board retaining wall.
Background technology
Retaining structure, including the structure type such as retaining wall, antiskid (anchoring) stake, anchor cable (bar), are filled out for supporting, reinforcing
Soil or slope soil, prevent from collapsing and slide to keep a kind of its stable building.Retaining wall is supporting and retaining system the most frequently used in engineering construction
Structure, it is mainly used in supporting embankment filled soil or slope soil, prevents from banketing or soil deformation unstability, bears the lateral soil pressure of the soil body
Power.Its purposes mainly includes：Execavated rockmass height is reduced, excavation quantity is reduced, avoids natural slope failure slump；Shrink embankment slope
Pin, fill yard and floor space are reduced, ensure roadbed reclamation；Avoid roadbed along river from squeezing 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, it is necessary to first set supporting and retaining system knot
Structure is filling roadbed again, and current stake plate type retaining wall is the supporting and retaining system pattern commonly used during Steep Slope Embankment fills.
Free arm formula peg board retaining wall by the pile body anchoring section being anchored in ground, the pile body cantilever segment to basset and
The breast boards between adjacent pile body cantilever segment and on the inside of stake is placed in form.The height of pile body free arm section can reach
15m or so, but after the height of free arm section is 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 Steep Slope Embankment retaining wall of the filled height more than 15m, occur in engineering practice
Prestressed anchor pull-type peg board retaining wall.It is between stable massif on the inside of 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 the pull-type peg board retaining wall of prestressed anchor is more than ground
Height can reach 20~25m.But in engineering practice, there is also problems with for the pull-type peg board retaining wall of prestressed anchor：In advance
The work progress of the pull-type peg board retaining wall of stress anchor is complicated, and technical difficulty is high, quality control difficulties；Massif on the inside of stake and stake
Between it is filling roadbed when, Highway Embankment Compaction and prestressed anchor draw the installation of facility to interfere with each other, and easily cause Highway Embankment Compaction degree and anchor
Rope prestressing force is not up to standard；Prestressed anchor draws the long-term reliability of facility and durability to be difficult to be guaranteed.
Utility model content
The purpose of this utility model is to provide a kind of rib stake formula peg board retaining wall.The rib stake formula peg board retaining wall is applied to steep
The retaining engineering of slope embankment, has that pile body deformation is small, supporting and retaining system effect is good, easy construction, construction costs are relatively low, good endurance
The characteristics of；And the anchorage depth of stake can be reduced, optimize the Cross section Design of stake.
The utility model is to realize that the technical scheme that its purpose of utility model uses is：A kind of rib stake formula peg board retaining wall,
Including pile body anchoring section, pile body cantilever segment, breast boards longitudinally disposed between adjacent pile body cantilever segment, it is characterised in that：Institute
The inner side for the pile body cantilever segment stated is fixedly connected with the floor laterally set.
Compared with prior art, the beneficial effects of the utility model are：
First, the utility model can be effectively improved the bending rigidity of stake, be subtracted significantly using being reliably connected between stake and floor
The lateral displacement of stake under small high cantilever state, further improves the jib-length of stake, and can reduce the anchorage depth of stake, optimizes stake
Sectional dimension.Floor in the utility model can substitute the effect of prestress anchorage cable, and due to being one between floor and stake
Act pour reliable to be fixedly connected, the defects of prestressd anchor cable loses as caused by becoming Xu can be overcome, ensure structure long-term work
Stability and durability.
2nd, the pull-type peg board retaining wall of existing prestressed anchor, its construct in need carry out anchor cable pore-creating, make anchor, apply anchor,
The anchor of a series of complex such as slip casting, construction anchor plate, tensioning, sealing off and covering anchorage draws process, and anchor draws process and embankment process phase
Mutually interference is big, and difficulty of construction is higher.And floor of the present utility model only need to be in concreting by connecting reinforcing bar by floor
It is connected with pile body cantilever segment, you can realize that the integration of the two is fixedly connected, its work progress is simple, the construction to embankment
Disturb small, integral construction difficulty is lower, and construction quality is high.
In a word, more traditional peg board retaining wall, the deformation of the utility model rib stake formula peg board retaining wall are reduced, work progress
Simplify, supporting and retaining system effect enhancing, the long-term work performance and durability of structure 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 utility model is applied widely, is also promoted the use of beneficial to it.
Construction method of the present utility model is
A) stake holes of pile body anchoring section is excavated, then the steel reinforcement cage of pile body anchoring section is hung in stake holes, and pours pile body anchor
Gu the concrete of section；
B) after the shaping of pile body anchoring section, horizontal floor groove is excavated on the inside of pile body anchoring section, and set up pile body cantilever
The template of section and the template of floor；
C) in b the steps template of pile body cantilever segment and the template of floor set up respectively the reinforcing bar of colligation pile body cantilever segment and
The reinforcing bar of floor, and connection reinforcing bar is set between pile body cantilever segment and floor；
D) concrete of pile body cantilever segment and the concrete of floor are poured, pile body cantilever segment is removed after reaching curing requirements
The template of template and floor；
E) longitudinally disposed prefabricated breast boards is layered between pile body cantilever segment, until wall top.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
