In traffic engineering field, field of urban rail, hydraulic engineering field and municipal field tunnel construction.Especially in city
Tunnel, submerged tunnel, city planting ductwork construction in, shield method, safe, high-quality, environmentally friendly, civilized construction quick with its etc. is many excellent
Gesture is increasingly becoming the first choice of all kinds of construction methods.But its construction risk can not still despise, and there are still cave in, gush in work progress
Water gushes the risks such as sand, especially shield launching or receives the stage.
Present shield reception end reinforcing mode mainly has rotary jet strengthening, stirring to reinforce, sleeve valve barrel grouting is reinforced, freezing adds
Gu the plain concrete joint reinforcement together with adding, these reinforcing modes must all carry out pipeline and change to move and traffic is led and changed, and carry out end
Nonetheless the outer operation of well collapsing also easily occurs during shield, leak, leaks phenomena such as mud, spillage, wind of constructing
Danger is huge, and causes receiver section shield tunnel faulting of slab ends, breakage and infiltration.Therefore, when conventional end reinforcement means because traffic,
When the factors such as pipeline can not be implemented, a kind of shield export & import soil body end ruggedized construction is needed to meet construction demand.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of shield export & import soil body ends
Ruggedized construction, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions:
A kind of shield export & import soil body end ruggedized construction, including soil stabilization area, after pour ring beam, shield circular tunnel and
Station pit building enclosure, the station pit building enclosure are set on the outside of two holes of shield circular tunnel, station base
Ring beam is poured after being equipped on the outside of pit enclosure structure, is equipped with soil stabilization outside the shield circular tunnel in station pit building enclosure
Area, soil stabilization area are the cube shaped plain concrete block poured, and soil stabilization area is covered on the hole of shield circular tunnel
Outside, the construction method that end reinforces in this bid section are rotary jet grouting form.
Further, the station pit building enclosure of side is glass fiber-reinforced polymer at the hole of the shield circular tunnel.
Further, the strength mark that the plain concrete block in the soil stabilization area uses for the concreting of C10 and
At.
Further, the length in the soil stabilization area at a hole of the shield circular tunnel be 6m, width 12m,
Height is 12m, with a thickness of 3m.
Further, the length in the soil stabilization area at another hole of the shield circular tunnel is 8m, width is
It 12m, is highly 12m, with a thickness of 3m.
Further, two hole diameters of the shield circular tunnel are 6m.
In conclusion the utility model has the advantages that compared with prior art
The shield export & import soil body end ruggedized construction of the utility model, station pit building enclosure are set to shield circle
On the outside of two holes in tunnel, ring beam, the shield in station pit building enclosure are poured after being equipped on the outside of station pit building enclosure
Soil stabilization area is equipped with outside structure circular tunnel, the construction method that end reinforces in this bid section is rotary jet grouting form, advantageous
Grouting and reinforcing condition can quickly and efficiently improve stratum, ensure that shield launching and received construction safety and periphery construction are built
Structure safety and normal use；Shield is simplified compared with conventional shield structure and receives technique, has simple process, technology first
Into, exploitativeness is strong the advantages that, compensate for the defect that China shield export & import soil body end reinforces reception technique, can obtain good
Economic benefit and social benefit.
