Description
Technical field
The invention belongs to foundation pit construction technical field, a kind of control closing foundation ditch construction of structures deformation is concretely related to
Means of defence.
Background technology
In recent years, Chinese urban construction and development is extremely rapid, and underground engineering is more and more, has emerged substantial amounts of foundation ditch
Engineering.These deep big foundation pit surroundings for being located at down town are gathered all kinds of underground utilities, close on all kinds of constructions of structures and subway tunnel
The facilities such as road.Because down town deep big foundation pit construction site is narrow and small, the construction period is tight, deep (depth is generally 15 to excavation of foundation pit
~25m), excavation of foundation pit area is big, and execution conditions are complicated;In addition the stratum residing for engineering is essentially saturated aqueous stream modeling or soft modeling
Argillic horizon, hole is the features such as when compressibility is big, shearing strength is low, sensitivity is high.The off-load of deep basal pit inevitably results in foundation ditch
And the stress field of surrounding soil changes, foundation ditch and foundation ditch surrounding soil strata deformation cause uplift of soil in foundation ditch, enclosed
The lateral deformation of protection structure and the sedimentation of foundation ditch periphery earth's surface.And in soft clay area deep pit excavation, not only to meet deep base
The intensity and safety and stability in hole itself, but also to control earth's surface outside the hole of the deformation and generation caused by deep pit digging
Sedimentation, to meet the requirement of protection surrounding enviroment.
At present, the method for the construction of structures for closing on excavation pit using conventional isolation pile technical protection has obtained certain answer
With, but when excavation of foundation pit have resulted in close on excavation pit construction of structures sedimentation and deformation it is excessive when, conventional isolation pile technology is just
Lose effect;In addition, when the construction of structures for closing on excavation pit uses pile foundation, also having using (i.e. remote on the outside of isolation pile
From foundation ditch side) protected mode of grouting and reinforcing, but this method is not suitable for shallow foundation Infrastructure because on the outside of stake slip casting main mesh
Be improve closed on by protection excavation pit construction of structures pile foundation side friction, improve its pile foundation non-deformability, and
Direct slip casting can cause the uneven upper lift of building on the contrary under shallow foundation Infrastructure, cause bulge fracture.
In addition, double-row pile technology has obtained certain development in recent years, close to having in existing building foundation pit stope support
There is some superiority, but Double-row Piles Support cost is higher, and pattern foundation pit supporting structure depth also has certain limitations, and supporting safety coefficient is relatively low, after

Sedimentation and deformation;
The closely connected arranged of gasbag 9 of vertically disposed inflatable/slip casting, each gasbag has each independent lead
To pipe 10, blast pipe 11, corresponding valve and respective real-time monitoring system 17 (pressure gauge).By inflating/slip casting to it, make
Air bag bag formation inflation/slip casting utricule, inflation/grouting pressure can be diffused to uniformly close under excavation pit construction of structures 2
Foundation soil in, can avoid directly in ground inflation/slip casting cause close on excavation pit construction of structures 2 it is uneven on lift
Protuberance.
(4) after the completion of excavation of foundation pit, the air in air bag is one by one discharged, while carrying out slip casting, being formed has necessarily
The pile body of rigidity;Specifically, total valve is closed, total pipeline is removed and connected on grouting equipment from air compressor,
Total valve is opened, while slowly opening the blast pipe 11 of the gasbag 9 of inflation/slip casting, slurry is slowly full of Nang bags;The row for the treatment of
There is slurry to overflow after a period of time in tracheae 11, you can to think that the gasbag 9 of the inflation/slip casting is already filled with, now close phase
Answer the valve in branch;After the gasbag 9 of all inflation/slip castings all fills slurry, the gasbag 9 of inflation/slip casting is carried out
Sealing of hole, and the top of all vertically disposed gasbags is connected by default steel pipe in the coupling beam of top and top coupling beam flexibility
Connect.
The gasbag volumetric expansion of inflatable/slip casting of the invention forms the pile body with larger diameter and certain rigidity, and
The stress release of surrounding soil caused by due to excavation of foundation pit can be carried out according to soil pressure and foundation pit deformation sedimentation measured result
Compensation, to control periphery construction of structures sedimentation, effectively reduces excavation of foundation pit to the disturbance of the construction of structures closed on.The present invention is solved
The problem of closing foundation ditch construction of structures settlement Control is difficult, overcomes other means of defences and has that cost is high, disturbance is big and efficiency
Low defect.The present invention has fast speed of application, strong adaptability, real-time, efficiency high, disturbs small, low cost and other advantages, is one
Plant very effective settlement Control means of defence.
