Further, support is set between the building enclosure of the Pipe rack both sides, and the support is positioned at Pipe rack Top.
Further, connected by piping lane bottom plate and building enclosure connector between the bottom plate and building enclosure of Pipe rack It connects.
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.
Further, piping lane excavation of foundation pit depth is 6 ~ 8m, and building enclosure is using Φ 600mm cast-in-situ bored piles, depth 14~16m;Support uses 609 steel pipes of Φ, 5 ~ 7m. of level interval.
Another object of the present invention 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 construction method.
In order to achieve the goal above, technical scheme is as follows:A kind of soft clay foundation adjoins High-filled emkankment synthesis Piping lane construction method, it is characterised in that this approach includes the following steps:
A, piping lane pile foundation is set;
B, construction building enclosure, and support is set between the building enclosure of piping lane both sides;
C, it is excavated to hole bottom after-pouring piping lane bottom plate, and piping lane bottom plate is connect with building enclosure;
D, construction Pipe rack;
E, the gap backfill between Pipe rack and building enclosure is backfilled to surface layer after removing support.
Further, the support is positioned at the top of Pipe rack
Further, the building enclosure is cast-in-situ bored pile, in step C, after piping lane bottom parts reinforcing bar extends and bends and Cast-in-situ bored pile principal rod effectively welds.
Compared with prior art, the present invention has the following advantages:
(1)The deformation control method that the invention is proposed takes full advantage of the anti-lateral deformation capacity of building enclosure, effectively controls Soft clay foundation 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 is protected Card;
(3)The more conventional design method of this method is compared, and is taken full advantage of the resistance to deformation function of building enclosure in service stage and is erected To supporting role, the dosage of piping lane pile foundation is significantly reduced, or even substitute piping lane pile foundation completely.
Description of the drawings
Fig. 1 is the construction technology sectional view of the present invention;
Fig. 2 is the construction technology plan view of the present invention;
Fig. 3 is the piping lane bottom plate and building enclosure connector schematic diagram of the present invention.
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 present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
A kind of soft clay foundation adjoins High-filled emkankment comprehensive pipe gallery structure, including Pipe rack 1,1 bottom of Pipe rack setting pipe Corridor pile foundation 2,1 both sides of Pipe rack are arranged building enclosure 3, support 4 are arranged between 1 both sides building enclosure 3 of the Pipe rack, The support 4 is located at the top of Pipe rack 1, and bottom plate and the building enclosure of the Pipe rack 1 form effective connection, make to go along with sb. to guard him Structure can control the lateral deformation of Pipe rack in service stage.
The present invention soft clay foundation adjoin High-filled emkankment pipe gallery construction technology, piping lane excavation of foundation pit on earth, 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 building enclosure 3 As an agent structure part, make building enclosure 3 that can control lateral deformation in service stage and improve Vertical Settlement and hold It carries, reaches 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 present invention is by permanently utilizing interim building enclosure, to control piping lane lateral deformation and Vertical Settlement.Described encloses Protection structure effectively controls lateral deformation, while by effectively being connect to bear pipe with piping lane bottom plate as a permanent structure part Corridor vertical load reduces engineering ordinary pile foundation dosage to undertake most of function of vertical support stake.
Construction method proposed by the present invention not only ensure that effective control to piping lane lateral deformation, but also will can temporarily go along with sb. to guard him Structure also can obviously reduce construction cost as a permanent structure part;Secondly, the technique is special to duration and construction nothing It is required that construction quality is easy to control, promotes and apply 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.
