Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
A kind of construction method of deep peat soil area construction operation platform includes the following steps: with reference to Fig. 1 and Fig. 2
A: hard ground at one is found in deep peat soil area 1, the hard ground can bear the weight of digging machine 5.Deep mud
1 soil property of charcoal soil area is soft, it is necessary first to look for starting point of the one piece of ground as operation.
B: delimiting the construction area of construction operation platform between the hard ground and construction point, and construction point, that is, engineering is applied
Building site point, such as the pile foundation construction point of bridge, in this case, construction operation platform is the channel into construction point, and construction area is applied
The contour line of work operating platform.
S1: arranging multiple control stakes 6 along the path of the construction area, also, described in the multiple control stake 6 is distributed in
The two sides of construction area, along the path direction of the construction area, two neighboring 6 spacing of control stake be third it is specific away from
From, if the path of the construction area is straightway, the third specific range is 20m, if, the path of the construction area
For curved section, the third specific range is 10m.
C: the digging machine 5 is moved on the hard ground.
D: in the range of the horn of the digging machine 5, usually 3 ~ 4m, excavates roadbed slot along the path of the construction area
2, namely remove the regional 1 surface soil layer of deep peat soil, big trees and tree root, weeds etc..
E: geotextiles 3 are laid in 2 bottom of roadbed slot, marshland section can overlay one layer of geotextiles 3, an excavation
After the completion of job step, geotextiles 3 carry out tunneling boring laying along job step.
F: backfilling sea sand into the roadbed slot 2, forms primary platform, and the primary platform can bear the digging machine 5
Weight, herein primary platform be only facilitate the continuation of digging machine 5 to move along the path of the construction area, so, returned in this step
Fill out the amount of sea sand and little.
G: the digging machine 5 is moved on previous step primary platform obtained;
H: repeating step D ~ G, until completing primary platform whole in the construction area;
Wherein, in steph, after every primary platform for completing the first specific range length, sea sand is backfilled above primary platform
And be compacted, form construction operation platform.First specific range is 40 ~ 60m, it is preferable that the first specific range is 50mm.
Specifically, digging machine 5 excavates foundation trench 2 and is formed primary platform and digging so that digging machine 5 moves in front
While machine 5 works, rear is synchronous to carry out backfilling working, and backfilling working all uses sea sand 4, and primary platform forms certain
After length, such as above-mentioned 50m, the sea sand 4 backfilled above it is compacted, and forms construction operation platform.Construction operation platform is formed
In the process, backfill and compacting can be performed in multiple times, until being backfilling and compacted elevation control, guarantee the mechanical equipment energy of basement process
Enough normal disengaging fields and operation.Elevation control is to be higher than existing Swampy Areas water level or the above 50cm(of original ground absolute altitude as guarantee machine
Tool normal operation, if it is necessary, construction operation platform filling height can be adjusted according to the actual situation) it is standard, and controlling
Mark is carried out in stake 6.
I: monitoring the absolute altitude of construction operation platform, and when its absolute altitude is lower than the second specific range of elevation control, second is specific
Distance can be 20cm, and backfill sea sand is simultaneously compacted, until the absolute altitude of operating platform is to elevation control.
J: repeating step I, until engineering terminates.
K: after engineering, excavating construction operation platform, and restores the regional 1 original place looks of deep peat soil, does not influence original
The function of flood discharge water storage.
The scope of protection of the present invention is not limited to this.Those skilled in the art are made equivalent on the basis of the present invention
Substitution or transformation, it is within the scope of the present invention.Protection scope of the present invention is subject to claims.
