Abstract
The invention discloses reception construction in a kind of shield structure hole, it is provided with confined chamber at the destination county of shield tunnel, in closed chamber, be full of water or other filler, shield machine is directly advanced into confined chamber from stratum while arrival, in confined chamber, complete shield machine and deviate from shield driving section, and utilize the grouting layer of shield tail to seal underground water, complete slurry shield and receive. When the present invention can prevent from constructing, underground water pours in, and avoids occurring ground subsidence, reduces construction wind, improves efficiency of construction.<!--1-->
Description
Technical field
The present invention relates to shield tunnel construction technology field, refer to that particularly one is applied in slurry shieldIn shield structure hole in machine, receive construction.
Background technology
Slurry shield machine is a kind of conventional tunnel construction machinery, and it is by pressurization mud hydraulic pressure and tunnelThe Water And Earth Pressures balance of road excavation face, and by the muddy water of circulation, the quarrel soil of cutting is carried and appearedOutward. The construction process of slurry shield machine is identical with general shield machine, has shield launching, normally pickEnter and the process such as shield structure reception, wherein to receive be the principal risk point of its construction in the arrival of slurry shieldAnd emphasis.
As shown in Figure 1, existing slurry balance shield arrive receive engineering method be before shield machine reachesThe outer soil mass consolidation 11 that is arranged with of active well 10, goes along with sb. to guard him knot when shield machine tunnels to active well 10When structure, cut the building enclosure at shield machine place, subsequently, shield machine is through being arranged on active well inwallInterim antipriming 12 after, be pushed into active well, in tunneling process simultaneously after segment assembly and wallGrouting layer between profile and the section of jurisdiction outer wall of laying of synchronous grouting filling shield machine excavation.
In use there is following problem in this reception programme:
1, shield machine is got rid of by muddy water after arriving active well building enclosure, because cutterhead excavation is straightFootpath is bigger compared with shield body, and in the larger stratum of permeability, underground water will be along shield machine housing and reinforcing bodyBetween gap pour in, if simultaneously reinforcing body occurs that flaw will also cause underground water to pour in, and thenGround subsidence occurs, and construction risk is large.
2, the interim antipriming waterproof effect that shield machine arrives is poor, constructional difficulties: existing shield structureArrive water-tight device and all adopt clamp plate type water-tight device, this device need be at shield machine shield body through sealingAfter device, manually promote clamp, withstand shield body water-tight device, on the one hand because side space under shield structure is narrowLittle, be manually difficult to enter construction; In addition, because of shield body be one fall capitate, in shield driving process,Clamp cannot clamp, and is difficult to reach purpose of design.
Therefore, need improve prior art.
Summary of the invention
Object of the present invention will provide exactly in a kind of shield structure hole and receive construction, above-mentioned to solveProblem in background technology.
Technical scheme of the present invention is: in a kind of shield structure hole, receives construction, it is characterized in that,It comprises the following steps:
1), shield tunnel destination county arrange confined chamber, in confined chamber, be provided with packing material;
2), when shield machine driving is when at shield tunnel terminal, muddy water enters in confined chamber and fillsMaterial mixes;
3), shield machine continues to tunnel in confined chamber, synchronously to profile and the laying of shield machine excavationSection of jurisdiction outer wall between grouting layer carry out slip casting;
4), shield machine tunnels while arriving shield tunnel terminal to the shield tail of shield machine, grouting layer slip castingComplete;
5), after the slurries in grouting layer solidify, remove confined chamber, shield structure completes.
In such scheme:
Described confined chamber is arranged on the destination county of shield tunnel, is provided with filling material in described confined chamberMaterial, the cross-sectional area of described confined chamber is greater than the cross-sectional area of shield tunnel.
Described packing material is water.
The abutted surface of described confined chamber and shield tunnel is that resin steel bar concrete walls are or/and obliqueThe soil body of support.
When the present invention can prevent from constructing, underground water pours in, and avoids occurring ground subsidence, reduces construction wind,Improve efficiency of construction.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
In existing shield structure hole, receive as shown in Figure 1 structure, in background technology, done detailed theoryBright, repeat no more in this.
In a kind of shield structure hole as shown in Figure 2 and Figure 3, receive structure, it comprises shield tunnel 2,The destination county of shield tunnel 2 is provided with confined chamber 1, and confined chamber 1 is provided with packing material, confined chamber 1Cross-sectional area be greater than the cross-sectional area of shield tunnel 2, confined chamber 1 section and length should be at leastEnsure that shield machine 6 passes through. Confined chamber 1 is to ensure before shield machine arrival with shield tunnel 2 abutted surfacesStability Analysis of Structures, can adopt resin steel bar concrete walls 4 or/and the soil body 3 of oblique support etc.
Packing material in the present embodiment is water, can be also: in muddy water enters confined chamber, closeIn closed chamber mud hydraulic pressure can with shield tunneling space in ground water pressure dynamic balance or be greater than underground waterThe other materials of pressure.
As shown in Fig. 4, Fig. 5, Fig. 6, a kind of adopt in shield structure hole described above receives structureConstruction, comprise the following steps:
1), shield tunnel 2 destination counties arrange confined chambers 1, in confined chamber 1, be provided with packing material;Wherein confined chamber 1 is connected interface according to interface stratum stability requirement with shield tunnel 2, can adoptBy modes such as soil body step, stratum consolidations, but must not there is the driving that hinders shield machine 6;
2), when shield machine 6 driving is when at shield tunnel 2 terminal, muddy water enters confined chamber 1In mix with packing material; The interior mud hydraulic pressure of confined chamber 1 can excavate the ground in space with shield machine 6Launching stress balance or be greater than groundwater pressure, avoids underground water to gush out; This step has ensured drivingGround water pressure dynamic balance in process, therefore the interim antipriming in existing design needn't be set, has reducedDifficulty of construction and construction risk;
3), shield machine 6 continues to the interior driving of confined chamber 1, the profile synchronously excavating to shield machine 68 and the section of jurisdiction outer wall 9 laid between grouting layer 7 by the mode of synchronous grouting, secondary groutingCarry out slip casting;
4), shield machine 6 tunnels while arriving shield tunnel 2 terminal to the shield tail 5 of shield machine 6, note7 slip casting of slurry layer are complete;
5), after the slurries in grouting layer 7 solidify, underground water seal completely remove confined chamber 1,Shield structure completes.
In the present invention, confined chamber 1, according to its design feature, hangs out shield machine after can directly removing,Also the plug wall that can remove shield structure front, shield machine hangs out shield machine after being advanced active well.
