As Figure 1-Figure 8, a kind of construction method being applied to the temporary support structures that place is quickly widened,
Use contrary sequence method, comprise the following steps:
(1), construction before prepare, first carry out wide field to be added ground base treatment, then according to design requirement add
Overhanging section of reinforcing bar of work anchor pole 1 and reinforcing bar pawl 7, and by reinforcing bar pawl 7 uniform welding in the reinforcing bar of overhanging section of anchor pole
Both sides；On anchor pole 1, it is spaced apart 300mm-500mm as the reinforcing bar pawl 7 described in preferred steps (1),
The a length of 150mm-200mm of reinforcing bar pawl 7, described reinforcing bar pawl 7 vertical direction arranges, is welded and fixed
On anchor pole 1 reinforcing bar, and make reinforcing bar pawl 7 vertical with anchor pole 1 reinforcing bar axis.
(2), construction time, first carry out bottom anchor pole 1 with between the body of slope construct, according to design require on protolith matter limit
The horizontal direction boring of slope, slope 6 body, fixing in anchor pole 1 inner slope body section reinforcing bar is stretched into anchor hole；As preferably
The slope body section reinforcing bar of the anchor pole 1 described in step (2) stretch into fixing in anchor hole after, to anchor hole and anchor pole 1
Gap location injects the strongest slurry.
(3), when strong slurry solidification morning injected in anchor hole is to prescribed strength, the sandbag 4 of rubble in using, is filled
It is applied on the reinforcing bar pawl 7 of overhanging section of anchor pole, after placing, sandbag 4 is alignd.
(4), transverse steel is connected with 1 overhanging section of reinforcing bar horizontal direction square crossing of anchor pole respectively；As
Transverse steel spacing described in preferred steps (4) is no more than 3m, and the spacing between transverse steel is preferred
For 3m, every 3m distance by transverse steel and 1 overhanging section of bar connecting of each anchor pole, it is used for strengthening supporting
The rigidity of structure, sandbag 4, anchor pole reinforcing bar 1 form main supporting construction with transverse steel 2.
(5), gravelly soil is used to fill up and cover sandbag 4 gap location；As preferred steps (5) medium stone soil
The mode using man-computer cooperation paves and flattens, paving thickness uniformity, surfacing；Wherein,
Manual is used in the range of 1.5m away from concrete topping 3.
The preferable sandy soil of certain grating, water penetration, broken (gravel) stone class soil preferentially selected by gravelly soil filler,
To ensure to play bigger frictional force between rib tape and filler, it is ensured that Stability Analysis of Structures；As preferably described
The diameter of gravelly soil filler is not more than 15cm.
(6), lay bar-mat reinforcement 5, make bar-mat reinforcement 5 connect with the reinforcing bar crotch 9 that 1 overhanging section of end of anchor pole is reserved
Connect, and to gunite concrete surface layer 3 at bar-mat reinforcement 5；
(7), after every layer of construction complete, above-mentioned construction procedure is repeated, until having constructed.
During this utility model support construction, carry out the vertical of top, slope and horizontal displacement, periphery earth's surface
Vertical Settlement and the monitoring of surface cracks, to ensure the safety of side slope, this utility model support construction mistake
Cheng Zhong, it is achieved that reduction of erection time, reduces the purpose of construction costs.
This utility model can be used in all kinds of engineering ground and widens in supporting construction, in specific embodiment temporarily
In, as shown in Figure 6, 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+total length caking property suspension roof support to complete,
Widen outside present former rock side slope 6.
As it is shown in figure 1, in work progress, first use concrete foundation 8, carry out the bases on ground, wide field to be added
According to design, reason, then requires that the anchor pole 1 of slope body section is stretched out in processing, every 500mm overhanging section of anchor pole 1
The reinforcing bar pawl 7 of reinforcing bar both sides weld length 150mm, direction is vertically perpendicular to reinforcing bar axis；Carry out again
The construction of the end one row's anchor pole 1, first carries out drilling construction at former rock side slope 6 slope body design attitude, puts into and add
Anchor pole 1 reinforcing bar after work, anchor hole injects the strongest slurry.
As it is shown in fig. 7, after slurry reaches some strength, the sandbag 4 filling rubble in using is applied in anchor pole 1
On the reinforcing bar pawl 7 of overhanging section；Every 3m distance by transverse steel 2 and 1 overhanging section of bar connecting of each anchor pole,
For strengthening the rigidity of supporting construction.
As shown in Figure 8, the gap location gravelly soil of sandbag 4 fills up and covers, and uses the mode of man-computer cooperation
Pave and flatten；Answer reserved steel bar crotch 9 at 1 overhanging section of end of anchor pole, be used for and gunite concrete face
Bar-mat reinforcement 5 in layer 3 connects；Lay bar-mat reinforcement 5, complete with the connection of reserved steel bar crotch 9 after, carry out
The construction of gunite concrete surface layer 3；After every layer of construction completes, repeat above-mentioned construction procedure, until having constructed
Become.
Wherein, this utility model concrete topping 3 uses C25 gunite concrete injection molding, coagulation
The thickness of soil surface layer 3 is 150mm, is built-in with φ 8@150 × 150 bar-mat reinforcement；The slope of former rock side slope 6
Top uses C25 gunite concrete injection molding, and the thickness of top, slope concrete layer is 250mm, built-in double-deck φ
8@150 × 150 bar-mat reinforcements.
It should be noted that and forbid preloading in the range of the 6m of top, former rock side slope 6 slope, the outer heap of 6m scope
Load value must not exceed 10kPa.
During construction, along with the vertical of top, former rock side slope 6 slope and horizontal displacement, periphery earth's surface
Vertical Settlement and the monitoring of surface cracks.
Monitoring and warning value is: level or vertical accumulation displacement reach 30mm, or rate of displacement reaches 2mm/d.When
Occur that following situations is for the moment, it is necessary to carry out danger warning immediately, and tackle in supporting construction and surrounding enviroment
