Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the easy structure of the utility model laying mountable steel bridge, including positioned at river two sides
Abutment 1, setting up between two abutments 1 has scaffold, and scaffold includes the vertical rod 2 being vertically arranged, and horizontally disposed horizontal stroke
Bar 3 and montant 4, vertical rod 2 are vertically inserted into riverbed, center line direction arrangement at least two row of the vertical rod 2 along two abutments 1, and two
Row vertical rod 2 is parallel to each other, and the center line side of the cross bar 3, the length direction of cross bar 3 and two abutments 1 is connected between same column vertical rod 2
To consistent, montant 4 is connected between cross bar 3, the length direction of montant 4 is vertical with the center line direction of two abutments 1.Each row vertical rod
2 restockings are provided with bridging 5, ensure the rigidity and intensity of scaffold.Cross bar 3 and montant 4 are two layers, and cross bar 3 and montant 4 are in vertical rod
Two platforms are formed at 2 top, are divided into top layer platform and underlying platform, mountable steel bridge 6 is laid on top layer platform.Bridging 5
In vertical rod 2 between top layer platform and underlying platform.
The width of abutment 1 is consistent with the width of mountable steel bridge 6, and two row vertical rods 2 are apart from the edge of homonymy mountable steel bridge 6
Horizontal range be 1m, i.e. width big 2m of the distance of two row vertical rod 2 compared with mountable steel bridge 6.Hound is also set up on the outside of scaffold
9, the spacing of adjacent hound 9 is 2m.Vertical rod 2 is two row, and the spacing of adjacent two vertical rods 2 of each column is 0.5m, on underlying platform
The spacing of adjacent two montants 4 is 1m, and the spacing of adjacent two montants 4 is 0.5m on top layer platform.
Such as Fig. 2, there is collapse rock-fall 7 between two abutments 1, if the overhead height of collapse rock-fall 7 and underlying platform height
Unanimously, the top of the collapse rock-fall 7 of exposure sets levelling concrete eight, and vertical rod 2, cross bar 3 and montant 4 are located at collapse rock-fall 7
On top or levelling concrete eight.If for the overhead height of collapse rock-fall 7 less than underlying platform height, the bottom of vertical rod 2 is located at avalanche
On falling rocks 7.Collapse rock-fall 7 is often larger, and the stability on riverbed is preferable, can bear larger pressure.
Certain power station is located on the tributary of Yunnan Province Huize County, and river valley two sides form is more symmetrical, the wide 30~45m of river, river
Depth of water 3m or so, bed material are ovum containing mud (broken) sand gravel layer (alQ4) and bulk collapse rock-fall, ovum (broken) sand gravel material
Composition is mainly dolomitic limestone, limestone, basalt, quartzy sandstone, and more in time corner angle~secondary round shape, a small amount of gravel is in perfectly round
Shape.Wherein, ovum (broken) general 60mm~100mm of stone particle diameter, accounts for 20%~25%；Grain size of gravel based on 30mm~50mm,
Secondary is 2mm~10mm, accounts for 50%~60%；20%~25% is accounted for for the sand filling containing shale, sand between coarse granule, its
Structure is more closely knit, and bearing capacity average value is 0.74MPa.Bulk collapse rock-fall is mainly dolomitic limestone, limestone, and scale is in 2m3
~4m3。
In order to engineering material requested transport, it is necessary in one individual layer mountable steel bridge of tributary restocking, design steel bridge 13 saves,
Long 3m is often saved, bridge floor is from water surface 3m or so.But locality does not set up the special erection equipment of this kind of steel bridge, by this practicality
The easy structure of new laying mountable steel bridge carries out setting up concretely comprising the following steps for work：
A. surveying setting-out, the abutment 1 for river both sides of constructing；Every section steel bridge is assembled simultaneously, and according to the suitable of assembling
Sequence is arranged in order standby.
B. the line centered on the center line of two abutments 1, scaffold building is carried out, the distance of two row vertical rod 22 is than abutment 1 wide two
Rice, wherein both sides are each wide one meter.To improve efficiency of construction, scaffold is set up to installation among river respectively from two abutments 1, is wrapped
It is 1m to include and set up vertical rod 2, cross bar 3 and montant 4, the spacing of each column vertical rod 2, and the spacing of montant 4 is also 1m.Vertical rod 2, should be anti-when setting up
It is multiple to insert several times more, make one of vertical rod 2 to enter the certain depth in riverbed, ensure its bearing capacity.Cross bar 3 and montant 4 are two layers, bottom
Layer platform is located above the water surface, and top layer platform is located at the position more slightly higher than abutment 1.Vertical rod between top layer platform and underlying platform
Bridging 5 is continuously set on 2, hounds 9 are set every two meters in vertical rod 2.
C. scaffold is reinforced and encrypted, vertical rod 2 and the spacing of montant 4 is changed into 0.5m；To on top layer platform
Montant 4 is encrypted, in order to which people walks.Scaffold construction, which can rely on manually will often save scaffold and carry on scaffold, is pacified
Dress.
D. steel bridge will be often saved to carry on top layer platform and carry out fabricated construction.
Finally, after steel bridge assembling construction, scaffold is removed.In stepb, if run into when setting up vertical rod 2 big
The collapse rock-fall 7 of type, levelling with concrete eight, based on it.Because large-scale collapse rock-fall 7 is larger, on riverbed
Stability it is preferable, larger pressure can be born.
The easy structure for laying mountable steel bridge only meets construction requirement by scaffold and artificial just reach, and solves and applies
Work problem, takes full advantage of existing resource.According to measuring and calculating, if the construction process of the mountable steel bridge according to routine, is about needed
6~70,000 yuan are wanted, but is constructed with this method, it is only necessary to which 30,000 yuan just complete construction, have saved the fund of more than half.
