Abstract
The utility model discloses a shield tunnel portal steel brush stagnant water structure, characterized by: and a water stopping steel wire brush is welded on the tunnel portal steel ring, and a water stopping structure is formed between the tunnel portal and the shield machine by the water stopping steel wire brush. The structure of the utility model is like the shield tail sealing steel wire brush structure of the shield machine, and can effectively play the role of water stop; the water-stopping device is particularly suitable for special areas, such as sediment strata with more underground water, confined water and the like, and has good water-stopping effect and high safety factor.
Description
Technical field
The utility model relates to the portal water-stopping structure in the running tunnel shield-tunneling construction.
Background technology
City underground is in the high speed development stage at present, meanwhile the safety of constructing tunnel is proposed higher requirement.In the running tunnel shield-tunneling construction, the portal antipriming that starts is to adopt turnover panel to add the mode of rubber curtain fabric swatch basically, receives portal in the mode of plate and latch plate, runs into the more stratum of underground water, the serious mud situation of leaking, leak can appear in shield structure turnover hole, has potential safety hazard.
Summary of the invention
The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of shield tunnel portal wire brush water-stopping structure is provided, to guarantee the reliable portal sealing in running tunnel shield launching and the reception construction, guaranteeing construction safety.
The utility model is that the technical solution problem adopts following technical scheme:
The characteristics of the utility model shield tunnel portal wire brush water-stopping structure are: at portal steel ring welding sealing wire brush, form water-stopping structure with described sealing wire brush between portal and shield machine.
The characteristics of the utility model shield tunnel portal wire brush water-stopping structure also are:
Described portal comprises start portal and reception portal.
Described sealing wire brush is multiple tracks.
The incline direction of described sealing wire brush is along the shield machine direct of travel.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, form of structure of the present utility model can play the sealing effect effectively as shield machine tail sealing wire brush structure.
2, the utility model is particularly suited for special location, and such as stratum such as the more silt stratum of underground water, artesian waters, stagnant water effect is good, safety factor is high.
3, wire brush can reuse in the utility model, reduces the wasting of resources, reduces use cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is sealing wire brush structural representation in the utility model;
Number in the figure: 1 shield machine; 2 portal steel rings; 3 sealing wire brushes; 4 portals.
The specific embodiment
Shield tunnel portal wire brush water-stopping structure is at portal steel ring 2 welding sealing wire brushes 3 in the present embodiment, as shield machine tail sealing wire brush, material is identical with shield machine tail sealing brush, forms water-stopping structure with sealing wire brush 3 between portal 4 and shield machine 1.
In the implementation, portal 4 comprises start portal and reception portal, and portal 4 shown in Figure 1 is the portal that starts; Sealing wire brush 3 is multiple tracks, can be set to twice, three roads or multiple tracks more according to hydraulic pressure size in the stratum; The incline direction of sealing wire brush 3 is along the direct of travel of shield machine 1.
In the present embodiment, after sealing wire brush 3 and 2 welding of portal steel ring are finished, between the steel wire of sealing wire brush 3 inside, be coated with full shield tail grease, because sealing wire brush 3 itself has good elasticity, and the sealing performance of shield tail grease, sealing wire brush 3 can be fitted tightly with shield machine 1, guarantee stagnant water effect.
Claims (4)
