Abstract
The invention discloses a kind of method that use prefabricated pipeline base plate does Brace in Deep Footing Groove, in Earthwork Construction of Deep Foundation, reinforced concrete support is based on horizontal pressure force, the intensity of reinforcing steel bar concrete support, it is not fully exerted as the characteristic that rigidity is big and deformation is small of the concrete of support, it is ensured that the installation security such as basis and surrounding buildingses, road and underground piping;Prefabricated pipeline base plate is placed in kerve, both as pipeline foundation, foundation ditch cross-brace is also served as.Supported using reinforced concrete in Soft Soil Foundation Pit engineering construction, due to its light and flexible, excavator can carry out lifting placement, with digging with putting, segmentation is excavated simultaneously, contributes to the operation simultaneously of many excavators, and shoveling speed is fast, and then shortens the duration of earth excavation.Adjustment prefabricated panel spacing and quantity, control the deformation of Retaining Structures in Excavation Engineering, and reduce the time of base pit dewatering, it is ensured that the safety of surrounding buildingses.
Description
Technical field
The present invention relates to municipal works drainage pipeline deep foundation pit support, belong to foundation ditch support technology field.
Background technology
In road drainage engineering, along road from east orientation west laying d1800-d2000mm storm sewers.Engineering d1800 rainwater
Pipeline start-stop pile No. is K0+563-K0+919.655, and total length 357m, cutting depth reaches 6.58~6.73m.D2000 rain pipes
Start-stop pile No. in road is K0+073.034-K0+563, and total length 490m, cutting depth reaches 6.93~7.26m.It is precast reinforced in advance mixed
Solidifying soil base plate, by taking d2000 pipelines as an example, prefabricated panel width 3.2m, length 1.5m, thickness 40cm are placed in kerve, are both made
It is pipeline foundation, also serves as foundation ditch cross-brace.
The content of the invention
The technical solution adopted by the present invention is a kind of method that use prefabricated pipeline base plate does Brace in Deep Footing Groove, in deep basal pit
In earthwork construction, reinforced concrete support based on horizontal pressure force because reinforced concrete support it is different from bracing members, its deform compared with
Method small, that arrangement of reinforcement and support enlarging section are taken in addition, the intensity of reinforcing steel bar concrete support, as the rigidity of the concrete of support
The big and small characteristic of deformation is not fully exerted, it is ensured that the installation security such as basis and surrounding buildingses, road and underground piping.Will be pre-
Tubing giving sufficient strength base plate is placed in kerve, both as pipeline foundation, also serves as foundation ditch cross-brace.
Supported using reinforced concrete in Soft Soil Foundation Pit engineering construction, due to its light and flexible, excavator can be carried out
Lifting is laid, and with digging with putting, is segmented and is excavated simultaneously, contributes to the operation simultaneously of many excavators, and shoveling speed is fast, and then shortening is dug
The duration of the earthwork.
At the same time prefabricated panel spacing and quantity can be adjusted according to soil property situation, controls the deformation of Retaining Structures in Excavation Engineering,
And reduce the time of base pit dewatering, it is ensured that the safety of surrounding buildingses.
Brief description of the drawings
Fig. 1 is organigram of the present invention.
Fig. 2 is organigram of the present invention two.
Specific embodiment
As shown in Figure 1-2, the present invention can effectively control foundation pit deformation and shorten the duration.Concrete operations are as follows:
S1, pipeline base plate are prefabricated, and prefabricated panel is designed into line label.
S2, steel sheet pile is beaten, be connected using seaming between stake and stake, be arranged by the suitable mode of a fourth one.
S3, excavation of foundation pit, excavation should follow " longitudinal divisionses, it is vertical layered, with support with dig, stretching top jail, strengthen monitoring "
Principle.Fluting soil is had bad luck outer to reduce tube seat lateral pressure to tube seat 20m.
S4, prefabricated panel is laid, prefabricated panel interval 1m lays, and lays one piece i.e. one piece of measurement, uses excavator
Elevation to base plate is adjusted.
Connected between S5, base plate, reinforced mesh is made in advance.After prefabricated panel leveling in place, reinforced mesh is carried out immediately
Install.
S6, subsequent construction, front prefabricated panel are laid after finishing and forming the scope of operation, and Pipe installing is carried out immediately.Pipeline
After installing a construction section, assuring and backfilling construction for pipeline is carried out immediately, then carry out steel sheet pile pile pulling and inspection shaft is applied
Work.
Embodiment
