Abstract
The utility model relates to the road surfaces in mine top plate water drenching tunnel to harden field, disclose a kind of hard surface in top plate water drenching tunnel, coarse sand bed course is set above the road bed, concrete precast block is set above the coarse sand bed course, gap is set between adjacent concrete prefabricated section, coarse sand or rubble are filled in the gap, gutter is arranged in coarse sand bed course side.The utility model laterally can penetrate into gutter to lower part coarse sand bed course by the coarse sand or rubble gap penetration that fill between concrete precast block in time after the water drenching of back drops onto road surface again, and tunnel road surface is avoided muddy, ponding problem occur.
Description
Technical field
The utility model relates to the road surfaces in mine top plate water drenching tunnel to harden field, relate more specifically to a kind of top plate water drenching
The hard surface in tunnel.
Background technique
Underground mine can inevitably encounter top plate water drenching phenomenon for the main roadway of personnel and vehicle pass-through, once drainage system
It is unsmooth, easily there is surface gathered water, miriness or cracking destruction problem, not only influences the passage environment of personnel and vehicle, and
Shorten the service life on road surface.Currently, the hardening of mine top plate water drenching tunnel road surface generally uses the side of one-piece casting concrete
Method, but difficulty of construction is big, concrete curing condition is poor in water drenching tunnel section for this method, and the construction quality on road surface is extremely difficult to design
It is required that.And easily occur the problems such as pavement cracking is destroyed with ponding, miriness in loaded vehicle roller compaction process, give personnel in the pit and Che
Passage bring difficulty.
Utility model content
For surface gathered water, miriness and the cracking destruction for solving the problems, such as mine top plate water drenching tunnel in the prior art, this is practical
It is novel that a kind of hard surface in top plate water drenching tunnel is provided.
The utility model adopts the following technical solution:
Coarse sand bed course, the coarse sand bed course is arranged in a kind of hard surface in top plate water drenching tunnel, the road bed top
Concrete precast block is arranged in top, and gap is arranged between adjacent concrete prefabricated section, and coarse sand or rubble are filled in the gap, described
Gutter is arranged in coarse sand bed course side.
The utility model can be in time by filling after the water drenching of back drops onto road surface between concrete precast block
Coarse sand or rubble gap penetration to lower part coarse sand bed course laterally penetrate into gutter again, avoid tunnel road surface from muddy, ponding occur
Problem.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the sectional schematic diagram after the hardening of the utility model tunnel road surface.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to attached drawing, the utility model discloses a kind of hard surface in top plate water drenching tunnel, above the road bed
Coarse sand bed course 4 is set, concrete precast block 1 is set above the coarse sand bed course 4, gap is set between adjacent concrete prefabricated section 1
2, the gap 2 is interior to fill coarse sand or rubble.
The concrete precast block 1 being laid on coarse sand bed course 4 is mutually indepedent, can be single when rolling during vehicle pass-through to it
It is solely pressurized, avoids pavement cracking caused by being rolled by loaded vehicle and destroy problem.
Gutter 3 is arranged in 4 side of coarse sand bed course, and the water drenching of back can pass through concrete precast block 1 in time
Between the coarse sand that fills or rubble gap penetrate into bottom cushion and laterally penetrate into gutter 3, play and exclude tunnel bottom in time
The effect of plate ponding.
The utility model construct below top plate water drenching roadway floor designed elevation 400mm depth basis and leveling, then
100mm thickness coarse sand bed course 4 is laid with using clean coarse sand, then is laid with 500mm × 500mm × 300mm(long on coarse sand bed course 4
× it is wide × high) cuboid concrete precast block 1.
When the concrete precast block 1 of the utility model is laid with, the gap of 30-50mm need to be reserved between concrete precast block
2(is adjusted according to water yield), the gap 2 between prefabricated section is filled using clean coarse sand or rubble after the completion of being laid with, is formed
The infiltration drainage system on road surface.
The concrete precast block 1 of the road surfacing of the utility model is independent from each other, it is ensured that it is in loaded vehicle roller compaction process
Middle independent compression, avoids pavement cracking caused by being rolled by loaded vehicle and destroys problem.
The utility model can be in time by filling after the water drenching when back drops onto road surface between concrete precast block
The coarse sand or rubble gap penetration filled out laterally penetrate into gutter to lower part coarse sand bed course again, and tunnel road surface is avoided muddy, product occur
Water problems.The utility model has construction is simple, safe and reliable advantage；It can solve the leaching of mine top plate by the utility model
Ponding, miriness and the cracking destruction problem on water tunnel road surface, greatly improve the passage condition of personnel and vehicle, while effectively prolonging
The service life and construction technology on long road surface are simple, and materials extensively, can voluntarily choose coarse sand according to back water drenching amount size
Or ballast grain sizes, designed, designed cushion thickness, concrete prefabricated block size and the pore size being laid between prefabricated section have very
Big application prospect.
