Description
Technical field
The utility model relates to a kind of immersed tube tunnel dry-docking toe ruggedized construction, belongs to dry-docking toe reinforcing technique field.
Background technology
Dry-docking, as an important temporary works of immersed tube tunnel, carries prefabrication of tube section, watertightness inspection, floating and the vital task such as to undock.Owing to belonging to large-scale foundation ditch near water, need reach the tube manufacture of time several years, experiencing the water-filling of dry-docking and the process that discharges water, therefore side slope is permanent stable, is the important indicator ensureing dry-docking safety.
Slope reinforcement traditional method, adopts the methods such as cement mixing pile soil stabilization, reinforced mesh bank protection or bolting support.Adopt cement mixing pile soil stabilization, stability is relatively good, but due to large-area soil stabilization, cost is high; Adopt reinforced mesh bank protection, affect comparatively large, therefore adopt reinforced mesh bank protection merely by foundation condition and ratio of slope, on the geological stratification that Unfavorable geology, artesian water enrich, the stability of side slope is poor; Adopt bolting support, because every root anchor pole needs to go deep in Rock And Soil by boring, just can carry out follow-up reinforced mesh laying and concreting, therefore the construction period is long, and cost is relatively high.
Summary of the invention
For above-mentioned prior art, the utility model provides a kind of large-scale immersed tube tunnel dry-docking side slope toe, and what be applicable to littoral facies weak soil geological stratification is constructed large-scalely puts slope non-support excavation pit, and this form of structure is both economic, practical, can the duration be ensured again, and enhance the stability of side slope.
For achieving the above object, the technical solution adopted in the utility model is large-scale immersed tube tunnel dry-docking side slope toe steel plate structure, this structure comprises prefabricated baffle plate 1, the wall back of the body reinforcing bar 6, rib post 3, anchor pole 4, anchor pole clamping bench 7, wherein reinforced concrete revetment 2 is the protective slope structure of dry-docking side slope, horizontal plane 5 is toe link position, the front end of rib post 3 is provided with tenon 3.2, and the rear end of rib post 3 is provided with wall heel slab 3.1.
Specifically, prefabricated baffle plate 1 is arranged on rib post 3 with on the rock-soil layer structure interface under reinforced concrete revetment 2; Wall back of the body reinforcing bar 6 is arranged in rib post 3, and to support the direction of rock-soil layer structure parallel with rib post 3; Anchor pole 4 is provided with two-layer up and down, and two-layer anchor pole 4 is all parallel with horizontal plane 5, and rock-soil layer is stretched in anchor pole 4 one end, and the other end is fastening by the inner surface anchor pole clamping bench 7 of rib post 3 front end; Reinforced concrete revetment 2 is fixed on above rib post 3.
Compared with prior art, the beneficial effects of the utility model are:
The utility model large-scale immersed tube tunnel dry-docking side slope toe steel plate structure, adopts multiple toe combination, by optimum design of structuresprogram, more easy, economic, practical, reaches the effect that side slope toe is reinforced equally.
Accompanying drawing explanation
Fig. 1 is the generalized section of large-scale immersed tube tunnel dry-docking side slope toe steel plate structure;
Fig. 2 is I portion lattice structure enlarged diagram in Fig. 1;
In figure: the prefabricated baffle plate of 1-, 2-reinforced concrete revetment, 3-rib post, 4-anchor pole, 5-horizontal plane, 6-wall back of the body reinforcing bar, 7-anchor pole clamping bench, 3.1-wall heel slab, 3.2-tenon.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in further detail.
As shown in Figure 1-2, large-scale immersed tube tunnel dry-docking side slope toe steel plate structure, this structure comprises prefabricated baffle plate 1, the wall back of the body reinforcing bar 6, rib post 3, anchor pole 4, anchor pole clamping bench 7, wherein reinforced concrete revetment 2 is the protective slope structure of dry-docking side slope, horizontal plane 5 is toe link position, the front end of rib post 3 is provided with tenon 3.2, and the rear end of rib post 3 is provided with wall heel slab 3.1.
Specifically, prefabricated baffle plate 1 is arranged on rib post 3 with on the rock-soil layer structure interface under reinforced concrete revetment 2; Wall back of the body reinforcing bar 6 is arranged in rib post 3, and to support the direction of rock-soil layer structure parallel with rib post 3; Anchor pole 4 is provided with two-layer up and down, and two-layer anchor pole 4 is all parallel with horizontal plane 5, and rock-soil layer is stretched in anchor pole 4 one end, and the other end is fastening by the inner surface anchor pole clamping bench 7 of rib post 3 front end; Reinforced concrete revetment 2 is fixed on above rib post 3.
This structure is by anchor pole 4, the wall back of the body reinforcing bar 6, prefabricated baffle plate 1 three kinds of textural associations, effectively the rock-soil layer stressing conditions of dry-docking side slope can be passed to rib post 3, the tenon 3.2 of rib post 3 front end and the wall heel slab 3.1 of rear end effectively can optimize the stressing conditions of rib post 3 simultaneously.
Embodiment
For tunnel, Haihe River dry-docking side slope, reinforced concrete revetment face thickness is 80mm, and concrete is C20.
Through phase authentication such as follow-up immersed tube prefabrication of tube section, pipeline sections leak detection (dry-docking water-filling), during excavating, surface settlement and sidesway value are 1.5mm/d ~ 2.3mm/d, are less than design load 3mm/d; Cheating outer SEA LEVEL VARIATION controls within 0.5m; Dry-docking comes into operation period, outside side slope and platform deflection thereof, hole, earth's surface section deflection, the outer soil body lateral displacement deflection in hole all do not exceed design alarming value, application in this construction of tunnel attains the results expected, and can be the technical support that similar engineering provides good.
