Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1 to 4, its structural relation is:
Green gravity retaining structures, comprises soil-baffling structure 1, also comprises water-storage controller 2, be provided with water-storage controller 2 in described soil-baffling structure 1.
Preferably, described soil-baffling structure 1 comprises the native main body 101 of gear, retaining room 102, spilled water hole 103 and filter pipe 104, retaining room 102 is provided with in the native main body 101 of described gear, top, described retaining room 102 is provided with spilled water hole 103, and transverse side is provided with filter pipe 104, is provided with water-storage controller 2 bottom described retaining room 102.Keep off in native main body 101 the retaining room 102 arranging a certain size, the water storage of retaining room 102 replaces part-structure material, has saved building material; When side slope 4 phreatic line 3 is higher, underground water infiltrates retaining room 102 by filter pipe 104, and retaining room 102 plays water storage function, and soil-baffling structure 1 is conducted oneself with dignity simultaneously increases, improve soil-baffling structure 1 and keep off native ability, reduce side slope 4 soil body to the Water And Earth Pressures of soil-baffling structure 1; Water storage also can be mended in slope soil by filter pipe 104 is counter, reduces soil erosion; When full water is stored up in retaining room 102, the drag of soil-baffling structure 1 reaches maximum value, and unnecessary water is concentrated from spilled water hole 103 and discharged, and is convenient to Collection utilization and directed discharge, and form the head pressure that the passage be communicated with suitably reduces side slope 4, improve the Antiseepage stability of soil-baffling structure 1.
Preferably, described water-storage controller 2 comprises water check valve 201, and gutter 202 and intercommunicating pore 203 are connected with gutter 202 bottom described retaining room 102, are provided with water check valve 201 in described gutter 202, and described gutter 202 is connected with intercommunicating pore 203.Be provided with water check valve 201 in gutter 202, effectively ensure the normal retaining of retaining room 102; In dry season or misery season, water check valve 201 pairs of water storages can be opened and make full use of.
Preferably, in the native main body of described gear 101, longitudinal direction is uniform is interval with retaining room 102, and the width of described retaining room 102 is 1.0m-2.0m, and the spacing of adjacent two retaining rooms 102 is 0.5m-0.8m.
Preferably, in the native main body of described gear 101, longitudinal direction is uniform is interval with retaining room 102, is communicated with between multiple retaining room 102 by intercommunicating pore 203.Multiple retaining room 102 is communicated with by intercommunicating pore 203, and the retaining line 105 of each retaining room 102 is highly identical, and the entirety that improve soil-baffling structure 1 uniformly keeps off native ability, also improves the Water And Earth Pressures of side slope 4 pairs of soil-baffling structures 1 simultaneously.
Preferably, described retaining room 102 transverse side is laid with at least two filter pipes 104.
During concrete use, whether the retaining line 105 according to retaining room 102 is divided into the green gravity retaining structures of fixed water bed and the green gravity retaining structures of mobile water bed with the change of side slope 4 soil body phreatic line 3.The whole participation structure checking computations of stable water storage of the green gravity retaining structures of fixed water bed; The green gravity retaining structures of mobile water bed is according to the design height of the fixed level of retaining room, and part water storage participation structure checks.During Antiseepage stability checking computations, slope soil adopts the pressure head of spilled water hole 103 height, if do not meet seepage resistance demand suitably can reduce spilled water hole 103 height.
The storage capacity of the green gravity retaining structures of fixed water bed is relatively strong, large to structural meterials substitution amount, can utilize retaining room 102 water body deadweight fully, improves the gear soil ability of soil-baffling structure 1.When side slope 4 phreatic line 3 is lower than fixing water storage water level, the stable storage of water storage, in retaining room 102, instead can not mend side slope 4 soil body by filter pipe 104, and the gear soil ability of soil-baffling structure 1 is stable and stronger; When side slope 4 water level is higher than fixing water storage water level, underground water enters retaining room 102 by filter pipe 104, after retaining room 102 is full of water, unnecessary water concentrates discharge to be convenient to Collection utilization and directed discharge from spilled water hole 103, in dry season or misery season, water check valve 201 pairs of water storages can be opened and make full use of.
The storage capacity of the green gravity retaining structures of mobile water bed is relatively weak, retaining room 102 water level changes with side slope 4 soil body phreatic line 3 within the specific limits and changes, water below the fixed level of its medium-term and long-term water storage, make full use of water body deadweight, reduce the constructional materials consumption of soil-baffling structure 1, the gear soil ability of soil-baffling structure 1 changes along with slope underground water bit line 3 height.When groundwater table is higher, retaining room 102 liquid level is relatively high, and the gear soil ability of soil-baffling structure 1 is relatively strong, after retaining room 102 is full of water, the gear soil ability of soil-baffling structure 1 reaches the strongest, and unnecessary water concentrates discharge to be convenient to Collection utilization and directed discharge from spilled water hole 103; When groundwater table is lower, the gear soil ability of soil-baffling structure 1 is relatively weak, and side slope 4 soil body is instead mended by filter pipe 104 in retaining room 102, is conducive to the water and soil conservation of side slope 4 soil body, preserves the ecological environment; When side slope side slope 4 water percolating capacity is comparatively large, water check valve 201 can be opened when Antiseepage stability exists potential safety hazard by gutter 202 to extracardiac pumping, fully reduce the head height of side slope 4, balanced and reduce Water And Earth Pressures, improve the stability of soil-baffling structure 1.
A gutter (202) can be set between the reservoir 102 of multiple UNICOM jointly, reduce the workload that gutter (202) is installed.
According to side slope 4 soil mass water seepage discharge a spilled water hole 103 can be set in each retaining room 102 or multiple connection retaining room 102 arranges a spilled water hole 103.
To sum up; the embodiment of the present invention has following beneficial effect: by retaining room, filter pipe and water-storage controller; available protecting side slope water and soil; conservation of nature ecological environment, carries out rational Distribution utilization to the water resource of storing in retaining room, utilizes retaining to supply deadweight; improve the native ability of gear; save buildings and resources, realize the focus utilization of superfluous water and directed discharge by the spilled water hole be communicated with, improve the problem that in the middle of speedway, greening nursing water resource haul distance is far away, pouring is difficult.
