Description
Technical field
The present invention relates to a kind of structure of the window of subterranean tunnel, relate in particular to a kind of structure of the window of shield tunnel.
Background technology
Tradition shield tunnel buried depth is deep, and is executing the dark larger working shaft of man-hour requirement construction.Follow the progress of the more harsh and Shield Construction Technique of tunnel line wiring condition, a kind ofly obtained certain application from ground discrepancy, shield tunnel that buried depth is more shallow.
, shield machine passes in and out from built active well side wall reserved opening when in conventional shield tunnel turnover the hole, and the later stage is carried out shutoff sealing.And the ground shield tunnel of coming in and going out starts from shallow base tunnel, without building active well, this just need to be for come in and go out a kind of new waterproof structure of the window of construction technology innovation and creation of shield tunnel of ground.
Therefore, those skilled in the art is devoted to develop a kind of structure of the window of shield tunnel, meets the demand of shield method tunnel construction, has improved greatly connection reliability and the water resistance of tunnel portal structure simultaneously.
Summary of the invention
Be different from prior art, technical problem to be solved by this invention is to provide one and meets shield method tunnel construction demand, can improve greatly the structure of the window of the connection reliability of tunnel portal structure and the shield tunnel of water resistance simultaneously.
For achieving the above object, the invention provides a kind of structure of the window of shield tunnel, the tunnel ends that is included in first moulding, is become by multiple pipe sheet assemblings, and at aftershaping, around the waterproof termination that is arranged on described tunnel ends external surface, and with the headwall of described waterproof termination integrated setting at described tunnel ends end; Described waterproof termination and described headwall are set in described tunnel ends; In described tunnel ends, preset dowel, described dowel is surrounded with steel band on position; In described waterproof termination, corresponding described steel band position is provided with sealing steel loop; Described steel band and seamless being fixedly connected with of described sealing steel loop.The weld seam infiltration of the moisture that described structure of the window is stopped tunnel outside from tunnel and junction, hole or tunnel ends, meets waterproof requirement and the connection reliability requirement of tunnel and base tunnel structure.
Preferably, described waterproof is also surrounded with rubber waterproof belt with expansion when in water in termination, and described rubber waterproof belt with expansion when in water is arranged on described steel band and described sealing steel loop intersection, near a side of described tunnel ends port, further improves water resistance.
Preferably, in described headwall, be embedded with anchor slab, be provided with the overhanging connector of part in described tunnel ends, described anchor slab is fixedly connected with described connector, further improves the reliability connecting.
Preferably, the weld seam of described steel band is arranged on the connecting sewing top between adjacent described section of jurisdiction, further improves water resistance and improves the reliability being connected.
Preferably, described waterproof termination is provided with in described headwall the reinforcing bar that one is connected, and further improves the reliability connecting.
Preferably, the structure of the window of described shield tunnel also comprises a pier base, and described pier base is arranged on the downside of described tunnel ends, prevents the differential settlement of structure of the window.
Therefore the present invention has met the demand of shield tunnel, can improve widely connection reliability and the water resistance of tunnel portal structure.The present invention is particularly useful for ground discrepancy method shield tunnel.
Below with reference to accompanying drawing, the technique effect of design of the present invention, concrete structure and generation is described further, to understand fully object of the present invention, feature and effect.

Detailed description of the invention
As shown in Figure 1, structure of the window one specific embodiment of shield tunnel of the present invention, described waterproof structure of the window is to meet tunnel 1 and base tunnel 2 to be reliably connected and the structure of the window of the shield tunnel of waterproof requirement.
As Figure 1-Figure 5, the structure of the window of a kind of shield tunnel of the present embodiment, the tunnel ends 3 that is included in first moulding, is become by multiple pipe sheet assemblings, and at aftershaping, around the waterproof termination 5 that is arranged on tunnel ends 3 outer peripheral faces, and with the headwall 4 of waterproof termination 5 integrated setting at tunnel ends 3 ends; Waterproof termination 5 and headwall 4 are set in tunnel ends 3.
As shown in Figures 2 and 3, preset dowel 6 in tunnel ends 3, corresponding dowel 6 position rings of tunnel ends 3 outer peripheral faces are wound with steel band 7; Interior corresponding steel band 7 positions, waterproof termination 5 are provided with sealing steel loop 8; Steel band 7 and seamless being fixedly connected with of described sealing steel loop 8 (for example welding).
In addition, be also surrounded with rubber waterproof belt with expansion when in water 9 in waterproof termination 5, rubber waterproof belt with expansion when in water 9 is arranged on steel band 7 and sealing steel loop 8 intersections, near a side of tunnel ends 3 ports.
Concrete, in the present embodiment, in headwall 4, be embedded with anchor slab 10, in tunnel ends 3, be provided with the overhanging screw rod 11 as connector of part, anchor slab 10 is fixedly connected with screw rod 11, the weld seam of steel band 7 is arranged on connecting sewing between adjacent section of jurisdiction top, waterproof termination 5 and the reinforcing bar 12 that is provided with one in headwall 4 and is connected.
As further improvement of this embodiment, the structure of the window of shield tunnel also comprises a pier base 13, and pier base 13 is arranged on the downside of tunnel ends 3.
Exemplary, below further illustrating for the application of the present embodiment:
In prior art, the hole place of shield tunnel is due to structure of the window, often exists and connects the unreliable and hidden danger such as leak, and is also not suitable for the come in and go out application of shield tunnel of ground simultaneously.The tunnel 1 of the present embodiment is to be started and constructed by base tunnel 2 by ground, does not need to set up active well, and by first building tunnel ends 3, the method that then waterproof termination 5 and headwall 4 are set forms structure of the window, and construction quality is higher, connects more reliably, and water resistance is better.
Adopt headwall and waterproof termination to water and wrap up in steel concrete integral structure, by the structures such as dowel, steel band, sealing steel loop and rubber waterproof belt with expansion when in water are set on tunnel ends and waterproof termination, stop the moisture in outside, tunnel from tunnel and junction, hole or the infiltration of the commissure tunnel ends, met waterproof requirement and the connection reliability requirement of tunnel and base tunnel structure.
Be fixed connection by screw rod default in pre-buried anchor slab and tunnel ends in headwall, further improved the reliability connecting; By a pier base is set at the downside of tunnel ends, prevent the differential settlement of structure of the window, also contribute to the maintenance of water resistance.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just can design according to the present invention make many modifications and variations without creative work.Therefore, all technician in the art, all should be in by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
