Abstract
The invention belongs to the field of tunneling, and particularly relates to an emergency subaqueous tunnel flood-prevention construction method for subaqueous tunnels. The method comprises the following steps: respectively burying steel plates on the driveway at the portal at the open section on both ends of the tunnel, and firmly connecting the steel plates with the pavement structure; welding channel-section steel plates above the buried steel plates to form a gate slot structure; arranging the gate steel plate in the gate slot to block the tunnel portal; and pouring slag earth into the tunnel portal from the ground outside the portal to form a mound, which abuts against the gate steel plate and resists the hydraulic pressure impact outside the portals at both ends of the tunnel. The construction method arranges the steel plate mound at the portal at the open section of the tunnel as the temporary flood-prevention measure, and can effectively prevent river water from injecting into the tunnel in an emergency. The construction method adjusts measures according to local conditions, and has the advantages of easy implementation, convenient construction and high speed.
Description
Technical field
The invention belongs to the construction of tunnel field, the concrete emergent flood-prevention construction method that is meant a kind of subaqueous tunnel.
Background technology
Build when getting over the river roads and tunnels problem that rivers water pours in down a chimney in the time of must considering emergency takes place.Lower such as the Urban Area of Shanghai City physical features, elevation generally is in 3.0～3.5m, is lower than long-term mean high water tidal level.As above at the bottom of the seawater tunnel rupture running into burst accident (as blast, earthquake, war or other), when destroying, river pours in the tunnel, and overflows rapidly thus to the city, will be life and the property that jeopardizes the people.
For preventing trouble before it happens, eliminate the risk that the tunnel causes the city to be flooded as intake tunnel under this special operation condition, must take certain temporary anti-flood measure as emergency preplan, with the tunnel closed at both ends, preventing that the tunnel from being flooded jeopardizes the city under case of emergency.Up to the present in the tunnel, all do not consider this situation.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of emergent flood-prevention construction method of subaqueous tunnel is proposed, secretly the section of burying hole is provided with the steel plate mound used as temporary anti-flood measure in the tunnel, and with the tunnel closed at both ends, anti-blocking river that can be instant pours into the tunnel under case of emergency.
Purpose of the present invention realizes being finished by following technical scheme:
A kind of emergent flood-prevention construction method of subaqueous tunnel, this job practices implementation step is as follows:
1) the handing-over openings position of the section of burying secretly in tunnel open section and tunnel is fixed in a troughing plate on the tunnel road surface structure that described hole is in tunnel open section one side;
2) the door steel plate is placed in the described troughing plate, forms the gate slot structure, block tunnel portal;
3) toward the interior impouring dregs of tunnel open section, form mound, against described door steel plate, the hydraulic pressure of resisting outside the hole, two ends, tunnel impacts.
Above-mentioned steps 1) be embedded with the track pre-embedded steel slab described on the tunnel road surface structure, described track pre-embedded steel slab is connected with described tunnel road surface sound construction, and described troughing plate is fixedly welded on the pre-embedded steel slab of described track; The plate face of described track pre-embedded steel slab keeps concordant with tunnel road surface;
The height and the width of the steel plate of door step 2) are all greater than the tunnel portal diameter;
Above-mentioned door steel plate is spliced by some precast plates.
Advantage of the present invention is, job practices of the present invention adopts in the tunnel secretly that the section of burying hole is provided with the steel plate mound as the temporary anti-flood measure, can prevent effectively that immediately in emergency circumstances rivers water pours into the tunnel, and applicability is stronger, job practices is suited measures to local conditions, and implements easy construction, quick easily.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation.
The specific embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Label 1-9 representative is tunnel open section 1, tunnel road surface (track) 2, track pre-embedded steel slab 3, road structure 4, troughing plate 5, door steel plate 6, mound 7, unlimited opening 8 in the accompanying drawing, and the tunnel is the section of burying 9 secretly.
For solving in emergency circumstances, river is poured into the subaqueous tunnel, an and difficult problem of invading the city rapidly, the inventive method secretly is provided with the steel plate mound used as temporary anti-flood measure in place, the section of burying handing-over hole in tunnel open section and tunnel, can be with the tunnel closed at both ends under case of emergency, preventing that the tunnel from being flooded jeopardizes the city, can be used as emergency preplan.
In the present embodiment, be example with the cross-river tunnel.At first, buried track pre-embedded steel slab 3 underground in the road structure of the open section 1 at two ends, tunnel and the section of burying 9 junctions secretly, pre-embedded steel slab 3 firmly is connected with road structure 4, and these step need be reconstructed the tunnel in advance, in a single day so that when burst accident taking place, can continue subsequent step.For ease of being open to traffic at ordinary times, the steel plate face of track pre-embedded steel slab 3 should should keep concordant with carriageway surfacing.
In case the generation accident is welded in the top of pre-embedded steel slab 3 with troughing plate 5, forms the gate slot structure; Again door steel plate 6 is placed in the described gate slot afterwards, blocks tunnel portal; At last, on the ground in the hole outside in the tunnel portal impouring dregs, form mound 7, against described door steel plate, resist the hydraulic pressure impact outside the hole, two ends, tunnel.
Stressing practical results property of whole construction method, emergency hangs in door steel plate 6 usefulness cranes in the gate slot when taking place as early as possible.Open section 1 upper position in tunnel is equipped with and opens wide opening 8, the dregs that vehicle is shipped on the ground in the outside, hole via the impouring in the tunnel open section of described unlimited opening 8.
In the present embodiment, will highly be about 7m with the automobile hanging device, some precast plates of width 1m, secretly the splicing of the section of burying hole arranges in the tunnel, is spliced into a steel plate.The height and the width of guaranteeing a steel plate cover tunnel portal fully all greater than the tunnel portal diameter.
In addition,, compress the single aperture of the required earth volume of water pressure (two tracks) and be about 350m3, need to consider the source problem that comes of soil amount because the required interim soil amount of sheetpile earthwork case is bigger.Proterties for mound does not have special requirement, oozes out as long as can satisfy the mound partition river of formation.
