Post and Guan Liang arrange Guan Liang anchor cable towards in slope soil as anchoring base, and put more energy into plain concrete columns with the shaped steel and enclose
Purlin is arranged towards in slope soil for anchoring base and encloses purlin anchor cable.
Railway slope shaped steel of the present invention put more energy into plain concrete columns combined support structure the characteristics of lie also in：The Guan Liang anchor cable
With enclose purlin anchor cable in slope soil towards downward-sloping.
Railway slope shaped steel of the present invention put more energy into plain concrete columns combined support structure construction method the characteristics of be by as follows
Step is carried out：
Step a, draw hole on slope construction platform and shaped steel is put in hole to designed elevation, pour and safeguard concrete shape
Put more energy into plain concrete columns into shaped steel；
The elevation of bottom of step b, the plain concrete columns excavation slope soil body to Guan Liang of putting more energy into along shaped steel, bores in anchor hole position
Hole is constructed, and inserts Guan Liang anchor cable, immediately slip casting after reaching drilling depth；
Step c, the position according to Guan Liang anchor cable and angle fix aperture after-pouring Guan Liang concrete, in the coagulation of Guan Liang
When native intensity reaches 100%, stress is applied to Guan Liang anchor cable；
Step d, the plain concrete columns excavation slope soil body of putting more energy into along shaped steel are bored to the elevation of bottom for enclosing purlin in anchor hole position
Hole is constructed, and purlin anchor cable is enclosed in insertion after reaching drilling depth, slip casting immediately；
Step e, basis encloses the position of purlin anchor cable and angle fixes aperture after-pouring and encloses purlin concrete, is enclosing the coagulation of purlin
When native intensity reaches 100%, apply stress to enclosing purlin anchor cable；Continue on shaped steel and put more energy into the plain concrete columns excavation slope soil body extremely
Substrate completes construction.
Compared with the prior art, the present invention has the beneficial effect that：
1st, the present invention is enable slope retaining to realize do mechanization operation, greatly reduces construction by improving supporting construction
The labor intensity of personnel.
2nd, the present invention has no effect on normal excavation construction, as side slope defines effective supporting, is greatly beneficial to
The guarantee of construction quality, improves work efficiency.
3rd, the present invention can extensively model suitable for various slope retainings construction, especially for short time limit, features as poor geologic condition, application
Region is wide, can greatly reduce construction safety risk.

Specific embodiment
Referring to Fig. 1, in the present embodiment, railway slope shaped steel plain concrete columns combined support structure of putting more energy into is：Along oriented railway
On the outside of the side slope in a row, and the vertical shaped steel of septal branch put more energy into plain concrete columns 1, shaped steel put more energy into plain concrete columns 1 be using shaped steel as
Beaer, ensures shaped steel position with plain concrete；It is provided with and encloses purlin in the put more energy into waist of plain concrete columns 1 of the shaped steel of Zhi Li in a row
4, the top setting Guan Liang 2 of plain concrete columns 1 of putting more energy in the shaped steel of Zhi Li in a row；Put more energy into plain concrete columns 1 and Guan Liang 2 with shaped steel
Guan Liang anchor cable 3 is set towards in slope soil 6 for anchoring base, and plain concrete columns 1 is put more energy into shaped steel and purlin 4 is enclosed as anchoring base
Seat is arranged towards in slope soil 6 and encloses purlin anchor cable 3；Guan Liang anchor cable 3 and purlin anchor cable 5 is enclosed in slope soil 6 towards downward-sloping.
In the present embodiment, the put more energy into construction method of plain concrete columns combined support structure of railway slope shaped steel is by following step
Suddenly carry out：
Step 1, draw hole using machinery on slope construction platform and shaped steel is put in hole to designed elevation, pour maintenance
Concrete forms shaped steel and puts more energy into plain concrete columns 1.
The elevation of bottom of step 2, the 1 excavation slope soil body 6 of plain concrete columns to Guan Liang 2 of putting more energy into along shaped steel, in anchor hole position
