Abstract
Existing railway increases road construction dike multiline pile earth-retaining construction, effectively to solve the problems, such as that existing railway increases road construction dike earth-retaining closing slope, ensures existing railway operation security, saves reconstruction project investment.Armored concrete supporter is set outside existing railway slope foot, and armored concrete supporter has the rectangle breast boards erect, web, and web is perpendicular to rectangle breast boards front face.Stake after stake, antidumping before basis is set in the stratum below the rectangle breast boards, web, and the upper end of stake is rigidly connected with rectangle breast boards before basis, and the upper end of stake is rigidly connected with web after antidumping.Increase road construction dike to fill out on existing railway in rectangle breast boards plate face rear side.
Description
Technical field
The present invention relates to existing railway to increase road construction dike earth-retaining technical field, and more particularly to existing railway increases road construction dike multiline pile
Earth-retaining constructs.
Technical background
Currently, as the quick of China railways cause is flourished, when existing railway cannot meet capacity development need,
Need to carry out increasing on existing railway to build two wires engineering.Increasing build in rail process, it is necessary to one lateral wall of existing railway it is wide fill it is new
Road construction base, since land used is nervous or engineering reasons, often needs closing slope earth-retaining.Traditional Gravity Retaining Wall, embankment pile plate wall
Deng rigid earth-retaining construction there are structure height is limited, horizontal earth-retaining scarce capacity, it is high to ground requirement for bearing capacity the problems such as；Reinforcement
The flexibility earth-retaining construction such as native barricade, Cantilever Retaining Wall, which is deposited, to be needed to excavate existing railway side slope in the construction process, seriously affects iron
The problem of road operation security.Therefore, there is an urgent need to a kind of earth-retaining ability is strong, structure height is big, easy construction, it is applied widely,
Ensure that the construction of existing railway operation security solves above-mentioned problem.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of existing railway and increase road construction dike multiline pile earth-retaining construction, to have
Effect solves the problems, such as that existing railway increases road construction dike earth-retaining closing slope, ensures existing railway operation security, saves reconstruction project investment.
Technical solution is as follows used by the present invention solves above-mentioned technology：
The existing railway of the present invention increases road construction dike multiline pile earth-retaining construction, including existing railway, it is characterized in that：It is described existing
Armored concrete supporter is set outside railway slope foot, and armored concrete supporter has the rectangle breast boards erect, web, web
Perpendicular to rectangle breast boards front face；In stratum below the rectangle breast boards, web before setting basis after stake, antidumping
, the upper end of stake is rigidly connected with rectangle breast boards before basis, the upper end of stake and web rigid connection after antidumping；Increase road construction dike
Filled out in rectangle breast boards plate face rear side on existing railway.
The invention has the advantages that the closing slope earth-retaining problem that existing railway increases road construction dike can be solved effectively, weight is overcome
Power formula barricade, embankment pile plate wall, reinforced earth bulkhead, the structure height of Cantilever Retaining Wall be limited, horizontal earth-retaining scarce capacity, serious
Influence the problem of railway operation is safe.Earth-retaining ability is strong, and structure height is big, and easy construction is applied widely, it is ensured that existing iron
The advantages of road operation security, and engineering land used 30%, construction investment 15% can be saved, there is good economy and ecological benefits.
Brief description of the drawings
This specification includes following three width attached drawing：
Fig. 1 is the sectional drawing that existing railway of the present invention increases road construction dike multiline pile earth-retaining construction；
Fig. 2 is the axonometric drawing that existing railway of the present invention increases road construction dike multiline pile earth-retaining constructed embodiment 1；
Fig. 3 is the axonometric drawing that existing railway of the present invention increases road construction dike multiline pile earth-retaining constructed embodiment 2；
Main member, toponym and corresponding mark are shown in figure：Increase road construction dike A, existing railway B, reinforced concrete
Stake 22 after stake 21, antidumping before native supporter 10, rectangle breast boards 11, web 12, basis.
Embodiment
The present invention is further illustrated below by specific embodiment and with reference to attached drawing.
Referring to Figures 1 and 2, existing railway increases road construction dike multiline pile earth-retaining construction, including existing railway B, the existing iron
Armored concrete supporter 10 is set outside the B slope foots of road, and armored concrete supporter 10 has the rectangle breast boards 11 erect, web
12, web 12 is perpendicular to 11 front face of rectangle breast boards；Basis is set in stratum below the rectangle breast boards 11, web 12
Stake 22 after preceding stake 21, antidumping, the upper end of stake 21 is rigidly connected with rectangle breast boards 11 before basis, the upper end of stake 22 after antidumping
It is rigidly connected with web 12；Increase road construction dike A to fill out on existing railway B in 11 plate face rear side of rectangle breast boards.
With reference to Fig. 1, rectangle breast boards 11, which blocks, increases road construction dike A, and the supporting rectangle of stake 21 breast boards 11 before basis, web 12 carries
For the horizontal supporting force to rectangle breast boards 11, stake 22 supports trapezoidal web panels 2 after antidumping, so that the level that will increase road construction dike A
Pressure conversion is the vertical pressure to stake after antidumping 22, tries hard to keep what card earth-retaining constructed by the vertical support of stake after antidumping 22
Monolithic stability.Have the characteristics that earth-retaining ability is strong, structure height is big, easy construction and applied widely, and need not excavate
The slope foot of existing railway B, can effectively ensure that guarantee existing railway operation security in work progress.
With reference to Fig. 3, to adapt to increase the different situations of road construction dike A, the web 12 can be along between the width of rectangle breast boards 11
Stake 21 can be also arranged at intervals along the width of rectangle breast boards 11 before setting, basis.
With reference to Fig. 1, the web 12 and the cast-in-place formation armored concrete supporter 10 of rectangle breast boards 11, the steel of web 12
Muscle is stretched into rectangle breast boards 11.To save concrete amount, the plate face of the web 12 is in up-small and down-big trapezoidal.The base
The reinforcing bar of stake 22 is respectively protruding into rectangle breast boards 11, in web 12 after stake 21, antidumping before plinth.
Some originals described above for simply increasing road construction dike multiline pile earth-retaining using existing railway of the present invention is illustrated and constructing
Reason, be not intended to by the present invention be confined to shown in and the concrete structure and the scope of application in, therefore every be possible to sharp
Corresponding modification and equivalent, belong to the apllied the scope of the claims of the present invention.
