Detailed description of the invention
Think that the reason of roadway floor argillization comprises: after roadway excavation, weathering disintegration very easily after the off-load of base plate mud stone; Digging laneway ponding is serious, sees with practical conditions, and ponding is mainly derived from rib infiltration and Shale fractures infiltration; The frequent roll off of fully-mechanized digging machine and haulage vehicle, this load transported more increases the weight of the argillization of base plate.
Wherein, the main cause of roadway floor argillization is water, and harnessing the river is the key link that solves roadway floor argillization.Through putting into practice and sum up for many years, the utility model provides a kind of precipitation cage, takes leading precipitation method to solve roadway floor argillization problem.

As Figure 1-Figure 4, the utility model provides a kind of precipitation cage, and this precipitation cage comprises: skeleton 1 and be wrapped in the filtration beds 2 of skeleton 1 periphery, wherein, skeleton 1 comprises at the bottom of cage wall 11, cage 12 and mobilizable cage lid 13.In the time that muddy water in roadway floor flows into this precipitation cage, the filtration beds 2 of first flowing through,, then enters in the space that skeleton 1 surrounds filterings such as the particles in muddy water by filtration beds 2.In cage wall 11, the part of laterally placing, plays fixing skeleton.Mobilizable cage lid 13 is convenient to accumulate in precipitation cage the cleaning of thing (not sandstone, the earth etc. of filtering).
Skeleton 1 can adopt i iron to be welded.In the utility model, the shape of skeleton 1 not being limited, can be tubular, and the cross section of tubular can be circular, ellipse or quadrangle, etc.Alternatively, skeleton 1, for cross section is tetragonal structure, so that make simply, is reduced to cost.
Precipitation cage cost provided by the utility model is low, is easy to processing and fabricating, can solve fast, expeditiously roadway floor argillization problem, reduces roadway floor argillization degree, and then ensures construction quality.
In the above-described embodiments, precipitation cage can also comprise water pump, and this water pump is arranged on the inside of precipitation cage, and is communicated to external environment condition by gutter.By water pump, the water of accumulating in precipitation cage is discharged.According to water yield, can select air pump or electric submersible pump.In roadway construction process, the ponding in pump drainage precipitation cage, seeps water to reduce as much as possible to roadway floor in time.
On the basis of above-described embodiment, in this precipitation basket structure, filtration beds 2 can comprise sand filter blanket 21 and filter screen 22 from outside to inside.The thickness of sand filter blanket 21 can be between 200 millimeters within the scope of 300 millimeters, sand filter blanket 21 can by yellow ground or particle diameter be no more than 3 millimeters microlith fill form.The reticular density of filter screen 22 can arrange according to geological structure and water quality situation etc., excessive to prevent reticular density, causes mesh to stop up, and dewatering effect is poor; Or, too small the caused poor filtration effect of reticular density, and then cause earth in precipitation cage to be accumulated, be unfavorable for the discharge of ponding.First there is sand filter blanket 21 to filter out the sandstone earth that granularity is larger, avoid mesh in filter screen 22 to stop up; Again by filter screen 22 secondary filters, double filtration can further reduce and enters the impurity that the water of precipitation cage comprises, and is beneficial to discharge.
In practical application, reticular density that can filter screen is 8 order/inches.In addition, filter screen 22 can adopt zinc-coated wire to make, and compared to iron wire, zinc-coated wire is difficult for getting rusty, and application life is longer.For example, filter screen 22 can be selected 8 order * 10 galvanized steel wire nettings.
Further, a visual through hole 14 can be set on cage lid 13, as shown in Figure 4 part in broken circle frame.By this visual through hole 14, user can observe the situation in precipitation cage easily, for example, and water accumulation level, or water pump situation, etc.
Before roadway construction, should first visit rear pick, first verify the rock texture and the water yield thereof that do not excavate tunnel, then according to the physical dimension in tunnel and construction method, precipitation cage can be arranged in to a side in tunnel; In the case of not affecting the construction in tunnel, also precipitation cage can be arranged in to both sides, tunnel, so that dewatering effect is better.In addition, precipitation cage, apart from the distance of work plane, in the situation that not affecting construction, should be tried one's best near work plane.In tunnel, can place multiple precipitation cages, the longitudinal separation of precipitation cage, can adjust at any time according to tunnel water yield and dewatering effect.And the physical dimension of precipitation cage also can specifically determine according to water yield, the utility model is not specifically limited.
In actual scene, at the pre-buried precipitation cage of tunnel one side, as shown in Figure 5 and Figure 6, make the water below roadway floor before roadway excavation prerequisite, infiltrate precipitation cage, thereby reduce to the water percolating capacity in roadway floor.Through Construction practices, this precipitation cage effect in work progress is very obvious, and the water content in roadway floor is greatly reduced, and the problem that base plate is broken into mud layer is solved, the progress that makes lane construction pass mud stone aquifer is largely increased, and construction cost is also significantly reduced.
Finally it should be noted that: above each embodiment, only in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or some or all of technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the scope of the each embodiment technical scheme of the utility model.
