Abstract
The utility model relates to tunnels, in particular to a pipe piece lining structure for drainage and decompression. The structure comprises a pipe piece lining ring formed by mutually splicing a plurality of pipe piece lining blocks, elastic lining cushions are arranged at the seam positions of adjacent pipe piece lining blocks, drainage decompression holes penetrating towards the back of a pipe piece wall is arranged on the pipe piece lining blocks, and reducing valves are arranged on the inner walls of the drainage decompression holes. On the basis of originally 'arranging a water-proof material and connectors between seams at the positions of the seams of the pipe piece lining blocks', by arranging the drainage decompression holes on the pipe piece lining blocks, and enabling the reducing valve to control opening or closing of the drainage decompression holes according to external water pressure, the pipe piece lining structure for drainage and decompression initiatively reduces water pressure out of a tunnel to a range which can be born by the elastic seal cushion and pipe piece lining and construction equipment .
Description
Technical field
The utility model relates to tunnel-like, refers to particularly a kind of pipe-plate lining structure with sluicing decompression.
Background technology
Shield tunnel and part TBM tunnel all adopt pipe-plate lining: be assembled into Lining Ring by the pipe sheet assembling equipment lining segment that floor manufacture is good during constructing tunnel, and space backfill behind the lining cutting ring wall is closely knit, bear the water and soil load by the pipe-plate lining that seals into ring.The pipe-plate lining ring generally is comprised of some lining segments, adopts related fittings to be an integral body between lining segment and the lining segment, between Lining Ring and the Lining Ring.
Section of jurisdiction self should standby water leakage ability member, but segment joint is the plane of weakness of waterproof, and is general by elastic sealing gasket or water-swellable waterstop pad sealing are set at adjacent segment joint place.In the prior art, the enclosed construction that namely utilizes connector between section of jurisdiction itself, seam waterproof material and seam (elastic sealing gasket or water-swellable waterstop pad) to form bears groundwater pressure and pressure from surrounding rock, and the problem of its existence has:
1, in high-water-pressure stratum, because water pressure is too large, need the larger tunnel segment structure of thickness, tunnel excavation amount and concrete material consumption are increased, economical not;
2, under long-term high Water Pressure, the easy seepage of seam affects operation of engineering projects safety and structure durability.
The utility model content
The purpose of this utility model is exactly according to above-mentioned the deficiencies in the prior art part, provides a kind of active tunnel external water pressure to be reduced to the pipe-plate lining structure of the sluicing decompression of the scope that elastic sealing gasket, pipe-plate lining and construction equipment can bear.
The technical solution of the utility model is: a kind of pipe-plate lining structure of the decompression that sluices, comprise the pipe-plate lining ring that mutually is spliced by a plurality of pipe-plate lining pieces, seam crossing at adjacent pipe-plate lining piece arranges elastic sealing gasket, be provided with the sluicing decompression hole that connects behind the wall of section of jurisdiction at described pipe-plate lining piece, be provided with reducing valve at the inwall of sluicing decompression hole.
Further, described sluicing decompression hole passes the packed layer in space behind the wall of section of jurisdiction.
Operating principle of the present utility model is: behind the tunnel piercing excavation, the segment assembly Lining Ring forms the waterproof construction of ring seal, at the seam crossing of adjacent pipe-plate lining piece elastic sealing gasket is set.Monitor by groundwater pressure during construction, when groundwater pressure bears restriction near elastic sealing gasket, pipe-plate lining and construction equipment, open the sluicing decompression hole that arranges on the pipe-plate lining piece, the filling that groundwater pressure pressure is distributed to behind the wall of section of jurisdiction is, and perhaps more a step is distributed to the country rock of pipe-plate lining periphery.After having constructed, the place arranges reducing valve at sluicing decompression hole inwall, when groundwater pressure reaches reducing valve and limits pressure, just can be by sluicing decompression hole automatic-discharging, but with assurance tunnel structure external water pressure within the tolerance range of tunnel structure.
But the utility model keeps the tunnel structure external water pressure within the tolerance range of tunnel structure by the sluicing decompression hole before construction, unlatching by reducing valve control sluicing decompression hole after the construction keeps the outer water pressure of tunnel structure, it is a kind of scheme of active sluicing step-down, and simple in structure, have great practical value.
Description of drawings
Fig. 1 is that the elastic packing packing ring arranges schematic diagram.
Fig. 2 is structural representation of the present utility model.
The schematic diagram of sluicing step-down when Fig. 3 is constructing tunnel.
Fig. 4 is the schematic diagram of sluicing step-down after the tunnel is completed.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the utility model, but they do not consist of restriction to the utility model.
As shown in Figure 1 and Figure 2, a kind of pipe-plate lining structure of the decompression that sluices, comprise the pipe-plate lining ring 3 that mutually is spliced by a plurality of pipe-plate lining pieces 1, seam crossing 4 between adjacent pipe-plate lining piece 1 is provided with elastic sealing gasket 2, on pipe-plate lining piece 1, also be provided with sluicing decompression hole 5, sluicing decompression hole 5 passes the packed layer in space behind the wall of section of jurisdiction, and enters in the country rock around the pipe-plate lining ring, in order to guarantee the sluicing antihypertensive effect; Inwall at sluicing decompression hole 5 is equipped with reducing valve 6, is used for the opening and closing of control sluicing decompression hole 5.
As shown in Figure 3, when tunnelling is constructed, by the monitoring of groundwater pressure, when groundwater pressure bears restriction near elastic sealing gasket 2, pipe-plate lining and construction equipment, open the reservation sluicing decompression hole 5 that arranges on the section of jurisdiction, with the groundwater pressure pressure decreased.
As shown in Figure 4, after constructing tunnel is finished, be provided with reducing valve 6 at sluicing decompression hole 5 inwalls, automatic-discharging when groundwater pressure reaches the restriction pressure of reducing valve 6, but to guarantee that the tunnel structure external water pressure is within the tolerance range of pipe-plate lining ring 3.
In this example, the concrete opening pressure of reducing valve 6 can be set according to the waterproof ability of segment joint, tunnel segment structure and spilled water hole arrangement etc.
The present embodiment is on the basis of original " connector between the waterproofing materials that pipe-plate lining piece seam crossing arranges and seam ", by at the pipe-plate lining piece sluicing decompression hole being set, and by reducing valve according to the unlatching of the hydraulic pressure control sluicing decompression hole in the external world whether, initiatively tunnel external water pressure is reduced in the scope that elastic sealing gasket, pipe-plate lining and construction equipment can bear.
