Description
Technical Field
The utility model belongs to the technical field of tunnel engineering construction, specific theory relates to a be used for TBM to construct unfavorable geology section and consolidate sleeper.
Background
In the construction of tunnel engineering such as water conservancy and hydropower, municipal administration, highway, railway and the like, when the TBM method is adopted for construction, temporary locomotive sleeper tracks need to be laid, personnel and material transportation is facilitated, because most TBM construction is only carried out for preliminary bracing, and inverted arch construction or bottom plate pouring are not carried out synchronously, when the TBM construction passes through poor geological sections such as V-type surrounding rocks and fault fracture zones, the laid locomotive sleepers cannot be installed on stable bedstones due to the fact that the stratum at the bottom of the tunnel is soft, the locomotive sleepers run for a long time, the sleeper tracks sink, and safety accidents of locomotive derailment are easily caused.
Therefore, it is necessary to provide a sleeper for reinforcing a poor geological section in TBM construction, which effectively prevents a sleeper rail from sinking and ensures safe and stable operation of a locomotive.
SUMMERY OF THE UTILITY MODEL
When harmful geology such as V class country rock and broken area of fault is passed through in order to overcome the TBM construction that exists among the background art, because tunnel bottom stratum is weak, on stable bed stone can't be installed to the locomotive sleeper of laying, the locomotive long-time operation has caused the sleeper track to sink, produces the incident problem that the locomotive derailed easily, the utility model provides a be used for TBM construction harmful geology section to consolidate the sleeper, effectively prevent the sleeper track from sinking, ensured the operation of locomotive safety and stability.
In order to achieve the above purpose, the utility model is realized by the following technical scheme:
the utility model provides a reinforced sleeper for a bad geological section of TBM construction, which comprises a connecting member 1, a bottom landing leg 2, a landing leg bottom base plate 3, a track 4 and a track pressing block 5; connecting elements 1 level arrange on the bow member 6 of unfavorable geological section, the both ends of connecting elements 1 bottom support the setting through bottom landing leg 2, bottom landing leg 2 is fixed on bow member 6 through landing leg bottom backing plate 3, threaded hole has been seted up at the both ends on connecting elements 1 upper portion, track 4 is installed at the both ends on connecting elements 1 upper portion to fix track 4 through track briquetting 5 and connecting elements 1 threaded connection.
Preferably, the two side edges of the bottom backing plate 3 of the supporting leg are provided with positioning screw pieces.
The utility model has the advantages that:
the utility model discloses simple manufacture, be convenient for installation and maintenance, the effect is showing in unfavorable geology section in-service use such as 5 types of country rock and broken area of fault, adopt the mode of erectting the sleeper on the bow member, the characteristics of the close hunch member of unfavorable geology section and the overall stability of bow member have been utilized, can prevent effectively that unfavorable geology section sleeper track from sinking the phenomenon that leads to the locomotive to derail, the safe and stable operation of locomotive has been ensured, locomotive safety transportation efficiency has been improved, thereby TBM tunnelling efficiency of construction has been improved, better social and economic benefits and application prospect have, be worth promoting and using.

Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-connecting component, 2-bottom supporting leg, 3-supporting leg bottom backing plate, 4-track, 5-track pressing block and 6-arch frame.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will make a detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1, the sleeper for reinforcing the poor geological section in the TBM construction comprises a connecting member 1, a bottom support leg 2, a support leg bottom base plate 3, a track 4 and a track pressing block 5; connecting element 1 level arrange on the bow member 6 of unfavorable geology section, the both ends of connecting element 1 bottom support the setting through bottom landing leg 2, bottom landing leg 2 passes through landing leg bottom backing plate 3 to be fixed on bow member 6, threaded hole has been seted up at the both ends on connecting element 1 upper portion, track 4 is installed at the both ends on connecting element 1 upper portion to fix track 4 through track briquetting 5 and connecting element 1 threaded connection, the utility model discloses mainly constitute by channel-section steel, I-steel and steel sheet welding, simple manufacture, be convenient for installation and maintenance, directly erect during the installation on the shaped steel bow member 6 that assembles, all install on every pin bow member 6 of unfavorable geology section, extend along the tunnel under, utilize the characteristics that bow member 6 is whole from the stationarity good, be difficult for subsiding yet to ensure that the locomotive operation is also for sinking when passing through the unfavorable geology section sleeper track, effectively guaranteed unfavorable geology section operation safety.
The edge of the two sides of the support leg bottom base plate 3 is provided with a positioning threaded part for clamping the two sides of the arch frame 6, so that the front and back displacement of the bottom support leg 2 in the operation process of the locomotive is prevented from falling below the arch frame 6, all welding parts are fully welded, the reinforcing sleeper is installed on each arch frame 6 of a bad geological section during installation, and the reinforcing sleeper extends along the front bottom of a tunnel.
The utility model discloses simple manufacture, the installation and the maintenance of being convenient for, effect is showing in unfavorable geological section in-service use such as 5 types of country rock and fault broken zone, can prevent effectively that the sleeper track from sinking and leading to the locomotive phenomenon of derailing, has ensured locomotive safe and stable operation, has improved locomotive safe transportation efficiency to improve TBM tunnelling efficiency of construction, had better social and economic benefits and application prospect, be worth promoting and using.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
