The purpose of project cost.
The present invention can be used in all kinds of engineering grounds and widen in supporting construction temporarily, in the particular embodiment, such as Fig. 6 institutes
Show, the slope height of former rock side slope 6 is 8.0m, and the width that need to widen is 4m.
Before widening construction, former rock side slope 6 has used prestress anchorage cable+overall length caking property suspension roof support to complete, now former
6 outside of rock side slope is widened.
As shown in Figure 1, in work progress, first using concrete foundation 8, the base treatment on wide field ground to be added is carried out, then
The anchor pole 1 for stretching out slopes section is processed according to design requirement, every 500mm 1 overhanging section of anchor pole reinforcing bar both sides weld length
The reinforcing bar pawl 7 of 150mm, direction is vertically perpendicular to reinforcing bar axis；The construction of most one row's anchor pole 1 of bottom is carried out again, first on protolith matter side
6 slopes design position of slope carries out drilling construction, 1 reinforcing bar of anchor pole being put into after processing, the early strong slurry of anchor hole injection.
As shown in fig. 7, after slurry reaches some strength, 1 overhanging section of anchor pole is applied in the interior sandbag 4 for filling rubble
On reinforcing bar pawl 7；Every 3m distances by transverse steel 2 and each 1 overhanging section of bar connecting of anchor pole, for enhancing the firm of supporting construction
Degree.
As shown in figure 8, the gap location of sandbag 4 is filled up and covered with gravelly soil, paved by the way of man-computer cooperation
With pressing；Reserved steel bar crotch 9 is answered in 1 overhanging section of end of anchor pole, for being connect with the bar-mat reinforcement 5 in gunite concrete face layer 3；
Bar-mat reinforcement 5 is laid with, after completing the connection with reserved steel bar crotch 9, carries out the construction of gunite concrete face layer 3；Every layer has been constructed
Cheng Hou repeats above-mentioned construction procedure, until construction is completed.
Wherein, concrete topping 3 of the present invention is using C25 gunite concrete injection moldings, the thickness of concrete topping 3
For 150mm, it is built-in with 8@of φ, 150 × 150 bar-mat reinforcements；The top of the slope of former rock side slope 6 uses C25 gunite concrete injection moldings,
The thickness of top of the slope concrete layer be 250mm, 8@of built-in bilayer φ, 150 × 150 bar-mat reinforcements.
It should be noted that forbidding preloading in the range of former 6 top of the slope 6m of rock side slope, the outer preloading value of 6m ranges must not surpass
Cross 10kPa.
During construction, along with the vertical and horizontal displacement of former 6 top of the slope of rock side slope, periphery earth's surface Vertical Settlement
And the monitoring of surface cracks.
Monitoring and warning value is：Horizontal or vertical accumulation displacement reaches 2mm/d up to 30mm or rate of displacement.It is following when occurring
Situation for the moment, it is necessary to carry out danger warning immediately, and cope with the protection object in supporting construction and surrounding enviroment take it is emergent
Treatment measures.
(1) monitoring data reach monitoring and warning value.
(2) shift value of supporting construction or the periphery soil body significantly increases suddenly.
Engineering construction and during use, should carry out walkaround inspection by special messenger daily, to supporting construction, construction operating mode, periphery
Environment, monitoring facilities carry out walkaround inspection, and Construction Party and other relevant units should be notified in time with dangerous situation by such as noting abnormalities.
The temporary support structures of the present invention quickly widened applied to place and its construction method, had both accelerated construction
Speed simplifies construction technology, and reduces engineering cost, and the place after widening can be used as temporary building place, life field
And emergency dealing temporary road etc..
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
