Abstract
The utility model discloses a combined structure of a duct piece lining structure and anchor rods. The combined structure comprise a pre-spliced duct piece lining structure, wherein a plurality of anchor rods are distributed outwards on the inner wall of the duct piece lining structure; and the anchor rods pass through the duct piece lining structure, and are fixed in the inner wall of a duct piece. In the combined structure, the tail ends of the anchor rods are fixed in the inner wall of the duct piece, so that a stress bearing structure is formed by the duct piece lining and the anchor rods; and when a part of the duct piece of a lining ring is detached, the duct piece lining and surrounding rock bear external load and the dead weight load of the duct piece together under the actions of the anchor rods. Compared with a conventional construction scheme in which an internal support is required to be arranged inside a tunnel close to an opened position, the combined structure has the advantages that greater convenience is brought, the transportation of materials of a front hole and muck are not influenced, and the stability of an opened structure can be ensured.
Description
Technical field
The utility model relates to tunnel-like, refers to particularly the combining structure of a kind of pipe-plate lining structure and anchor pole.
Background technology
Shield tunnel and part TBM tunnel all adopt pipe-plate lining: be assembled into the pipe-plate lining ring by the pipe sheet assembling equipment pipe-plate lining piece 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, and the mode such as employing bolt is connected as a wholely between piece and the piece and between ring and the ring, makes pipe-plate lining become the bearing structure of closed stablity.
When existing pipe-plate lining needs partial dismantling to build annex, the stability of former Lining Ring structure will be destroyed.For keeping the stability of hatch frame, as shown in Figure 1, tunnel internal must arrange inner support bar 1 near opening, its shortcoming is: construction is inconvenient, namely when construct simultaneously in the positive hole of ancillary building and tunnel, inner bracing piece 1 takies the transport channel in positive hole, affects the material and the transportation of quarrel soil in positive hole.
The utility model content
The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, provides a kind of and can guarantee the stable of hatch frame, does not take again the pipe-plate lining structure of construction transport space in positive hole and the combining structure of anchor pole.
The technical solution of the utility model is: the combining structure of a kind of pipe-plate lining structure and anchor pole, comprise the pipe-plate lining structure, inwall in described pipe-plate lining structure is outwards arranged a plurality of anchor poles, and described anchor pole passes the pipe-plate lining structure, and fixing in the inwall of section of jurisdiction.
Preferably, described anchor pole radially arranges along the circumference of pipe-plate lining structure.
Operating principle of the present utility model is:
The tunnel is behind driving excavation, and the segment assembly lining cutting uses filler to fill space behind the lining wall; After void filler solidifies behind the lining wall, outwards arrange a plurality of anchor poles that radially arrange along its circumference at the inwall of pipe-plate lining structure, anchor pole passes the pipe-plate lining structure, and fixing in the inwall of section of jurisdiction.The spacing of anchor pole and length are determined jointly according to wall rock condition, the pipe-plate lining of tunnel perimeter.After pipe-plate lining structure+anchor pole forms stable combining structure, i.e. the pipe-plate lining of dismountable local opening part.
The utility model makes pipe-plate lining and anchor pole jointly form the carrying force structure because the tail end of anchor pole is fixed on the section of jurisdiction inwall; After removing the local section of jurisdiction of Lining Ring, because the effect of anchor pole, make pipe-plate lining and country rock acting in conjunction bear external loads and section of jurisdiction gravity load, the constructure scheme of inner support must be set than near traditional tunnel internal opening, convenient, and the material in the positive hole of impact and the transportation of quarrel soil can not guarantee again the stable of hatch frame.
Description of drawings
Fig. 1 is existing pipe-plate lining hatch frame schematic diagram.
Fig. 2 is the utility model pipe-plate lining structure+anchor pole combining structure schematic diagram.
Fig. 3 is the utility model pipe-plate lining structure+anchor pole combining structure opening scheme schematic diagram.
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.
Such as Fig. 2, shown in Figure 3, the combining structure of a kind of pipe-plate lining structure and anchor pole, comprise the in advance pipe-plate lining structure 2 of splicing, inwall in pipe-plate lining structure 2 is outwards arranged a plurality of anchor poles 3 that radially arrange along its circumference, anchor pole 3 passes pipe-plate lining 2, and fixing in the inwall of pipe-plate lining structure 2.
During specific implementation: the tunnel is behind driving excavation, and segment assembly liner structure 2 uses filler to fill space 5 behind the lining wall; After 5 fillers of space behind the lining wall solidify, outwards arrange a plurality of anchor poles 3 at pipe-plate lining 2 inwalls, anchor pole 3 passes pipe-plate lining structure 2, and fixing in the inside of pipe-plate lining structure.The spacing of anchor pole 3 and length are determined jointly by condition, the pipe-plate lining structure 2 of the country rock 4 of tunnel perimeter.After pipe-plate lining structure 2+ anchor pole 3 forms stable combining structure, i.e. the section of jurisdiction 6 of dismountable local opening part.
The utility model makes pipe-plate lining structure 2 and the anchor pole 3 common carrying force structures that form, after removing the local section of jurisdiction 6 of Lining Ring, because the effect of anchor pole 3, make pipe-plate lining 2 and country rock 4 actings in conjunction bear external loads and section of jurisdiction gravity load, the constructure scheme of inner support must be set than near traditional tunnel internal opening, convenient, and the material in the positive hole of impact does not transport with quarrel soil, can guarantee the stable of hatch frame.
Claims (2)
1. the combining structure of a pipe-plate lining structure and anchor pole comprises the pipe-plate lining structure, it is characterized in that: the inwall in described pipe-plate lining structure is outwards arranged a plurality of anchor poles, and described anchor pole passes the pipe-plate lining structure, and fixing in the inwall of section of jurisdiction.
2. the combining structure of pipe-plate lining structure according to claim 1 and anchor pole, it is characterized in that: described anchor pole radially arranges along the circumference of pipe-plate lining structure.
