Description
Technical field
The utility model relates to tunnel basis technical field more particularly to a kind of dual waterproof constructions of shield duct piece.
Background technique
Subway tunnel has become development trend using shield construction at present, since shield-tunneling construction has ground adaptability
By force, without precipitation, construction safety is reliable, speed is fast, can effectively control surface subsidence, to periphery disturb it is small, to traffic above-ground
The superiority such as small are influenced, it is particularly suitable that civil construction is carried out in the specific environment of city, and obtained good result.But underwater tunnel
Road for shield machine should have there is also seep water, collapse etc. structural instabilities the case where.Wherein, shield duct piece waterproof is important
One ring.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of dual waterproof of shield duct piece is provided
Structure, which can obtain preferable stability and waterproofness in shield tunnel under water, and structure is simple, easy to make.
In order to achieve the above purposes, the technical solution adopted by the utility model is: a kind of dual waterproof construction of shield duct piece, institute
Stating waterproof construction includes section of jurisdiction, filleting, sponge rubber item, elastic rubber gasket, hydro-expansive rubber item；The section of jurisdiction is
The concrete slab of arc, is divided into outside and inside, and section of jurisdiction is close to outside, there are filletings；Sponge is installed on the outside of the filleting
Rubber strip；It is equipped with elastic rubber gasket in the filleting, is equipped with hydro-expansive rubber item on the inside of elastic rubber gasket.
Preferably, the elastic rubber gasket uses the ethylene-propylene-diene monomer increased compared to general land-based area section width dimensions
Elastomeric seals pad.
The beneficial effects of the utility model are: the structure can obtain preferable stability and waterproof in shield tunnel under water
Property, and structure is simple, it is easy to make.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is shield duct piece waterproof construction schematic diagram.
Wherein: 1 is section of jurisdiction, and 2 be filleting, and 3 be sponge rubber item, and 4 be elastic rubber gasket, and 5 be hydro-expansive rubber
Item.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown, a kind of dual waterproof construction of shield duct piece, the waterproof construction includes section of jurisdiction 1, filleting 2, sponge
Rubber strip 3, elastic rubber gasket 4, hydro-expansive rubber item 5；The section of jurisdiction 1 be arc concrete slab, be divided into outside and
Inside, section of jurisdiction 1 is close to outside, there are filletings 2；Sponge rubber item 3 is installed on the outside of the filleting 2；It is set in the filleting 2
Flexible rubber gasket 4 is equipped with hydro-expansive rubber item 5 on the inside of elastic rubber gasket 4.
In specific implementation, the elastic rubber gasket 4 is using the ternary second increased compared to general land-based area section width dimensions
Third caoutchouc elasticity gasket 4.
When practice of construction, in every two sections of jurisdiction, 1 junction there are filleting 2, set on the outside of section of jurisdiction filleting 2 a sponge rubber item 3 every
Sand hinders mud, carries out caulking sealing in reserved 2 slot of filleting with elastic rubber gasket 4, and inside sets hydro-expansive rubber item 5,
Form perfect section of jurisdiction self waterproofing system.
