Technical Field
The utility model belongs to municipal construction field relates to utility tunnel construction, concretely relates to take vibrator from wall type utility tunnel foundation ditch backfill auxiliary device.
Background
Along with the trend of people to good life in recent years, the demand for expansion of underground pipelines is urgent. Traditional direct-burried mode of laying is difficult to satisfy the demand, and the pipeline that exceeds does not plan, and the pipeline is complicated in the crossing department's pipeline complicacy simultaneously to lead to during the construction to cut off water and cut off the power supply etc. and bring very big puzzlement for life production. The urban infrastructure is an important carrier for guaranteeing urban space expansion and improving urban functions, and the construction of the urban underground comprehensive pipe gallery is an important component in the infrastructure.
Because city utility tunnel all buries underground in having built urban road below, in order to avoid causing urban traffic jam and large tracts of land to destroy urban road, when the construction of city utility tunnel underground, the excavation supporting generally adopts the stake support of SMW worker method or the support of Larsen steel sheet pile. The gallery body in the support mode of the piles in the SMW method is constructed in a wall-mounted mode, the support section steel can be directly pulled out after the construction of the pipe gallery main body is completed, and then soil on the upper portion of the gallery body is backfilled; and the gallery body is constructed from the wall when the Larsen steel sheet pile supporting form is adopted, after the construction of the main body of the pipe gallery is completed, a coiled material waterproof layer is pasted outside the main body, then an extruded sheet is pasted to protect the waterproof layer, when deep and narrow foundation pits on two sides are backfilled, the traditional operation generally adopts a back-shoveling type excavator to directly grab soil for backfilling, because the soil body has downward impact force and friction force with the extruded sheet, the extruded sheet is extremely easy to damage, the waterproof layer is further damaged, the water leakage of the pipe gallery is caused, the repair of the waterproof layer outside the gallery body is extremely difficult, and the irreversible quality problem is caused. Because the gallery body both sides foundation ditch is narrower, the soil body descends slowly and blocks near gallery body roof easily when backfilling, and not only the efficiency of construction is low, and the degree of compaction of backfill soil in the deep narrow foundation ditch is hardly satisfied the design requirement moreover.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a take vibrator to backfill auxiliary device from wall type utility tunnel foundation ditch to solve the inconvenient problem of backfilling of utility tunnel soil body among the above-mentioned background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model relates to a take vibrator from wall type utility tunnel foundation ditch backfill auxiliary device, including preceding baffle, preceding baffle is positive glossy steel sheet, and the back is equipped with a high frequency vibrator, the below of preceding baffle is equipped with a reentrant corner draw-in groove, preceding baffle upper portion and back backup pad welded connection, back backup pad with preceding baffle middle part is equipped with a connecting plate, the connecting plate both ends with preceding baffle with back backup pad welded connection constitutes triangle-shaped stable structure.
Further, the high-frequency vibrator type is the attached flat plate vibrator, the high-frequency vibrator pass through the bolt with the front baffle is connected, the high-frequency vibrator passes through the on-the-spot tertiary electronic box power supply of building site.
Furthermore, the rear supporting plate is made of a steel plate, the upper portion and the middle portion of the rear supporting plate are stably connected with the front baffle, and the bottom surface of the rear supporting plate and the upper portion of the internal corner clamping groove are located on the same horizontal plane.
Furthermore, the connecting plate is a selected steel plate and can form a triangular stable structure together with the front baffle and the rear supporting plate.
Further, reentrant corner draw-in groove can coincide completely with corridor body external corner, and can provide stable holding power for preceding baffle and whole device.
Compared with the prior art, the beneficial effects of the utility model are that:
take wall type utility tunnel foundation ditch backfill auxiliary device of vibrator, its modern design, simple structure, the preparation is convenient, excellent in use effect. Can avoid the backfill soil to directly strike the destruction that brings to the outside waterproof layer of corridor and extruded sheet effectively to the quality problem of piping lane percolating water has been avoided. Meanwhile, the high-frequency vibrator can enable the soil body to fall more dispersedly and more quickly, so that the self gravity of the soil body is utilized to reach a compact state, the efficiency of the off-wall type underground comprehensive pipe gallery is greatly improved when the foundation pit is backfilled, the engineering quality is guaranteed, the construction cost is saved, and the off-wall type underground comprehensive pipe gallery has a wide application prospect.
