Abstract
The utility model provides the building enclosure that a kind of municipal pipeline crosses foundation pit, including outside building enclosure and inside building enclosure；Wherein, outside building enclosure includes supporting main body and steel plate, and supporting main body is arranged along foundation pit periphery and the part in municipal pipeline periphery is opposite extends out and disconnect at municipal pipeline to form fracture, and fracture goes along with sb. to guard him region using steel plate reinforcement；Inside building enclosure includes drilled pile, rotary churning pile and crown beam, and drilled pile and rotary churning pile arrangement are fixed below municipal pipeline, and crown beam is set at the top of drilled pile and is connect by beams of concrete with supporting main body.The technical solution of the utility model, the bilayer combination gone along with sb. to guard him using outside building enclosure and drilling on inner side stake not only can be effectively to pipeline in-situ conservation, and does not influence it using function, has saved and has changed the expense of moving, the human cost of engineering；Meanwhile also ensuring safety compared with deep basal pit, and engineering risk is reduced, it is with good economic efficiency.
Description
Technical field
The utility model relates to the realm of building construction, and in particular to a kind of foundation pit supporting construction that pipeline crosses.
Background technique
When the municipal pipelines such as high-tension cable, major diameter rain sewage pipe culvert cross base pit engineering, due to changing the expense of moving, work
Phase, using the limitation of the conditions such as function, do not have and move the condition of changing, this is just necessarily required to carry out the municipal pipeline for crossing foundation pit former
Position protection, thus will cause certain influence to the integrality of the building enclosure of foundation pit, it is steady so as to cause the whole safety of foundation pit
Qualitative decline.Existing solution, which is usually building enclosure, crosses in pipeline and disconnects at position, by the soil body on the outside of foundation pit
The measures such as reinforcing, bell hole weld steel plate guarantee the safety of foundation pit and municipal pipeline.But when excavation of foundation pit depth it is larger, geology
In the case where complicated condition, such as the big sandy soil stratum of water penetration, deep silly stratum, just easily occur leak, gush mud,
The risks such as foundation pit deformation is excessive.In this regard, just needing to provide a kind of solution effect superior technique scheme.
Utility model content
The purpose of the utility model is to overcome disadvantage existing in the prior art, provide that a kind of structure is simple, protection pipe
The foundation pit enclosure structure that the good municipal pipeline of deep pit monitor stability crosses while line is unaffected.
To achieve the goals above, the technical solution adopted in the utility model is as follows:
A kind of municipal pipeline crosses the building enclosure of foundation pit, including outside building enclosure and inside building enclosure；Wherein, outside
Side wall protection structure includes supporting main body and steel plate, and supporting main body is arranged and is in the part phase on municipal pipeline periphery along foundation pit periphery
Fracture is formed to extending out and disconnecting at municipal pipeline, fracture goes along with sb. to guard him region using steel plate welded closure；Inside building enclosure
Including drilled pile, rotary churning pile and crown beam, drilled pile and rotary churning pile arrangement are fixed below municipal pipeline, and crown beam is set to drilled pile
It top and is connect with supporting main body by beams of concrete.
Further, drilled pile and rotary churning pile alternatively, sectionally are arranged.
Further, the arrangement total length of drilled pile and rotary churning pile is greater than the diameter of municipal pipeline.
Further, the vertical range of drilled pile and rotary churning pile apart from municipal pipeline is not less than 5m, meets construction requirement.
Further, beams of concrete and drilled pile top crown beam keep same absolute altitude.
Further, steel plate and supporting main body reinforcement welding, the closing drilled pile top above fracture of crown beam go along with sb. to guard him region.
The technical solution of the utility model, the bilayer combination gone along with sb. to guard him using outside building enclosure and drilling on inner side stake, not only
Can be effectively to pipeline in-situ conservation, and it is not influenced using function, it has saved and has changed the expense of moving, the human cost of engineering；Together
When, it also ensures the safety compared with deep basal pit, reduces engineering risk, it is with good economic efficiency.
Detailed description of the invention
Fig. 1 is the planar structure schematic diagram of the utility model.
Fig. 2 is the A-A cross-sectional view of the utility model.
Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
Referring to attached drawing.The utility model is the bilayer combination structure of outside building enclosure and inside building enclosure.Wherein, outside
Side wall protection structure includes supporting main body 1 and steel plate 2.Supporting main body 1 is existing deep foundation pit supporting structure, such as deep-layer stirring water
Soil piling wall, hole-drilling interlocking pile, cast-in-place diaphram wall etc. can be specifically chosen according to different foundation pit situations.Supporting master
Body 1 is arranged along foundation pit walls and opposite extend out in the shape of a " convex " in the part in 3 periphery of municipal pipeline is that inside building enclosure reserves
Installation space.Supporting main body 1 disconnects forming fracture at municipal pipeline 3.Fracture is by municipal pipeline 3 and fracture goes along with sb. to guard him region
It is reinforced using 2 welded closure of steel plate.
Inside building enclosure includes drilled pile 4, rotary churning pile 5 and crown beam 6, and drilled pile 4 and rotary churning pile 5 are alternately arranged segmentation
It is arranged in 3 lower section of municipal pipeline, crown beam 6 is set to 4 top of drilled pile and connect by beams of concrete 7 with supporting main body 1, to bore
Hole stake 4 forms the double-deck supporting construction with supporting main body 1.Beams of concrete 7 guarantees same mark with the crown beam 6 for being set to 4 top of drilled pile
Height, steel plate 2 and 1 reinforcement welding of supporting main body, 6 or more the fracture of crown beam at 4 top of closing drilled pile go along with sb. to guard him region.
Specifically, drilled pile 4 and vertical range of the rotary churning pile 5 apart from municipal pipeline 3 are not less than 5m, and the arrangement of the two is total
Length should be greater than the diameter of municipal pipeline, to guarantee the stability of inside building enclosure.
It should be pointed out that the embodiments of the present invention are described above.However, the technical staff of art technology should manage
Solution, the present utility model is not limited to the above embodiments, only illustrates the principles of the present invention described in above-described embodiment,
There are many changes and improvements for the utility model also meeting under the premise of not departing from the scope of the utility model, these changes and improvements are all
It falls within the scope of the claimed invention.
