Abstract
The utility model discloses a kind of soft clay foundations to adjoin High-filled emkankment pipe gallery, including Pipe rack, piping lane pile foundation is arranged in Pipe rack bottom, building enclosure is arranged in Pipe rack both sides, the bottom plate of the Pipe rack forms effective connection with building enclosure, so that building enclosure is become a part for piping lane agent structure, the lateral deformation of Pipe rack can be controlled in service stage.The utility model is by permanently utilizing interim building enclosure, to control piping lane lateral deformation and Vertical Settlement.The building enclosure effectively controls lateral deformation, while undertaking most of function of vertical support stake by effectively being connect with piping lane bottom plate to bear piping lane vertical load, reduces engineering ordinary pile foundation dosage as a permanent structure part.
Description
Technical field
The utility model is related to a kind of soft soil foundations to adjoin High-filled emkankment pipe gallery, be particularly suitable for foundation deformation needs
The soft clay foundation that 1 year or more consolidation of experience could be stablized.
Background technology
Pipe gallery is developed rapidly in recent years at home, especially in the soft clay areas such as riverine, coastal due to existing
Deep soft clay foundation, adjoin it is new fill out roadbed side and build pipe gallery when, due to the time effect of bury deformation, for a long time
Destruction of the lateral deformation to the destruction of piping lane significantly more than vertical differential settlement to piping lane, but long-term lateral deformation
Piping lane destruction is not paid attention in current designs.
Traditional piping lane Deformation Control Design is but tightly only right to pile foundation simply by designing vertical pile foundation under piping lane bottom plate
Improve piping lane vertical deformation and bearing capacity is helpful, and to improving lateral deformation（Especially when using the prefabricated pile for having connector）
It is then very limited.
Utility model content
The purpose of this utility model is exactly to provide one kind in order to overcome defect existing for existing design technology and ensure that and apply
The safety of work, the soft clay foundation of Deformation control validity adjoin High-filled emkankment pipe gallery.
In order to achieve the goal above, the technical solution of the utility model is as follows：A kind of soft clay foundation adjoins High-filled emkankment
Piping lane pile foundation is arranged in pipe gallery, including Pipe rack, Pipe rack bottom, and building enclosure, institute is arranged in Pipe rack both sides
It states the bottom plate of Pipe rack and building enclosure forms effective connection, building enclosure is made to become a part for piping lane agent structure.
Further, support is set between the building enclosure of the Pipe rack both sides, and the support is positioned at Pipe rack
Top.
Further, the building enclosure be cast-in-situ bored pile, piping lane bottom parts reinforcing bar extend and bend after with drilling
Bored concrete pile principal rod effectively welds.
Compared with prior art, the utility model has the following advantages：
（1）The deformation control method that the utility model is proposed takes full advantage of the anti-lateral deformation capacity of building enclosure, has
Effect controls soft clay foundation and adjoins the deformation of High-filled emkankment pipe gallery, ensure that the safety of construction；
（2）The construction technology is simple and easy to do, does not increase process additionally, and construction quality is easy to control so that the construction period obtains
To guarantee；
（3）The more conventional design method of this method is compared, and the resistance to deformation function of building enclosure is taken full advantage of in service stage
It is acted on vertical support, significantly reduces the dosage of piping lane pile foundation, or even substitute piping lane pile foundation completely.
Description of the drawings
Fig. 1 is the construction technology sectional view of the utility model.
Fig. 2 is the construction technology plan view of the utility model.
Fig. 3 is the piping lane bottom plate and building enclosure connector schematic diagram of the utility model.
Figure includes：Pipe rack 1, building enclosure 3, supports 4, foundation pit bottom surface 5, piping lane bottom plate and encloses piping lane pile foundation 2
Protection structure connector 6, High-filled emkankment 7, piping lane bottom plate 8.
Specific implementation mode
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
Embodiment 1
A kind of soft clay foundation adjoins High-filled emkankment comprehensive pipe gallery structure, including Pipe rack 1, and 1 bottom of Pipe rack is set
Piping lane pile foundation 2 is set, 1 both sides of Pipe rack are arranged building enclosure 3, branch is arranged between 1 both sides building enclosure 3 of the Pipe rack
Support 4, the support 4 are located at the top of Pipe rack 1, and bottom plate and the building enclosure of the Pipe rack 1 form effective connection, make
Building enclosure can control the lateral deformation of Pipe rack in service stage.
The soft clay foundation of the utility model adjoins High-filled emkankment pipe gallery construction technology, is arrived in piping lane excavation of foundation pit
Piping lane bottom plate is connect with building enclosure connector 6 by piping lane bottom plate with building enclosure 3 when pouring bottom plate, makes to go along with sb. to guard him by bottom
Structure 3 becomes an agent structure part, makes building enclosure 3 that can control lateral deformation in service stage and improve vertical sink
Drop and carrying, reach Comprehensive Control piping lane Amoebida.
The main technique engineering of this method：Construction piping lane pile foundation 2 first, building enclosure 3 of then constructing, then in piping lane
The soil body to foundation pit bottom surface 5, setting piping lane bottom plate in hole is excavated between the building enclosure of both sides after setting support 4 with building enclosure to connect
Bottom plate is effectively connect by fitting 6 with building enclosure, Pipe rack 1 of then constructing, empty between Pipe rack 1 and building enclosure 3
Gap backfill is backfilled to surface layer after removing support 4.The building enclosure is cast-in-situ bored pile, and piping lane bottom parts reinforcing bar extends
And 9 are effectively welded with cast-in-situ bored pile principal rod after bending.
In the present embodiment, the sectional dimension of Pipe rack 1 is 10m（It is wide）×6.0m（It is high）, piping lane excavation of foundation pit depth
For 7m；Piping lane pile foundation 2 uses Φ 500PHC pile piles；Building enclosure 3 uses Φ 600mm cast-in-situ bored piles, depth 15m；Branch
Support 4 uses 609 steel pipes of Φ, level interval 6m；Piping lane bottom plate is filled by extending baseplate reinforcing bar with drilling with building enclosure connector 6
Note stake principal rod effectively welds.
The utility model is by permanently utilizing interim building enclosure, to control piping lane lateral deformation and Vertical Settlement.It is described
Building enclosure as permanent structure a part, effectively control lateral deformation, while by effectively being connect to hold with piping lane bottom plate
By piping lane vertical load to undertake most of function of vertical support stake, reduce engineering ordinary pile foundation dosage.
The utility model proposes construction method not only ensure that effective control to piping lane lateral deformation, but also can will be interim
Building enclosure also can obviously reduce construction cost as a permanent structure part；Secondly, the technique is to duration and construction nothing
Special requirement, construction quality are easy to control, and are promoted and are applied convenient for engineering.
Piping lane pile foundation dosage deducts the vertical deformation that building enclosure can bear and bearing capacity is determined again, with abundant
Utilize building enclosure efficiency.If building enclosure can all bear vertical deformation and bearing capacity, then piping lane pile foundation can be substituted completely.
