Abstract
The utility model discloses a flexible net-shaped check dam, which comprises a flexible protecting mesh. A supporting rope is arranged around the edge of the protecting mesh, and an anchor stock used for fixing the protecting mesh is connected on the supporting rope. The check dam adopts the flexible protecting mesh, when the construction is performed, the check dam can not be restricted by the environmental condition, the flexible protecting mesh is provided with unloading function, an independent spillway is not needed to be arranged, the construction process can be reduced, and the construction difficulty can be descended, the flexible protecting mesh can duly perform the unloading to the water, and the dam failure phenomenon can not be caused because the unloading operation can not be duly performed to the water.
Description
Technical field
The utility model relates to a kind of protector that can be used for protecting mud-rock flow, relates in particular to the netted check dam of a kind of flexibility.
Background technology
Check dam is in erodible raceway groove, for fixing ditch bed and soil, the stone building built.The check dam accumbency highly is generally less than 3m in raceway groove, mainly act as and raise the erosion basic point, prevents the bottom of trench incision; Raise the ditch bed, stablize the hillside toe, prevent the expansion of ditch bank; Slow down the raceway groove longitudinal gradient, reduce the mountain torrents flow velocity, alleviate the harm of mountain torrents or mud-rock flow; Retain silt, make bottom of trench stepization gradually, create conditions for utilizing the production of raceway groove land development.
In the prior art, check dam is pressed the constructional materials difference, is divided into native check dam, mortarless stone check dam, tip branch check dam, willow check dam, mortar stone check dam, bamboo cage dress stone check dam, concrete check dam, steel concrete check dam etc., and is the most general with stone check dam, native check dam.Soil, stone check dam are laid in generally that geological conditions is good in the erosion groove, engineering quantity is little, retain the place that runoff and sediment is many, engineering material is sufficient; The plant check dam should be located at that the gradient is mild, in thicker soil and the moistening raceway groove.Check dam generally is arranged in hondo upstream or the big hair ditch of longitudinal gradient, and the position should be chosen in the ditch section that raceway groove is narrow, sediment trapping storage capacity is big, geological conditions good, can gather materials on the spot.The check dam planning and designing to the effect that determine height of dam, spacing and cross dimensions, highly bigger under the identical condition of raceway groove longitudinal gradient, then spacing is bigger, the check dam height should be definite according to constructional materials, raceway groove geology, orographic condition.In order to lead flood safely off by check dam, spillway need be set, the design peak flood flow that its size is calculated by catchment area, design storm, runoff coefficient etc. is determined.
Adopt the check dam of above-mentioned form mainly to have the following disadvantages: one, generally can only be arranged on the place that raceway groove is narrow, sediment trapping storage capacity is big, geological conditions good, can gather materials on the spot, be subjected to the environmental factor restriction bigger during construction.Two, independent spillway need be set, increase construction technology, improve difficulty of construction.Three, easily cause moisture drain charge in time, cause dam break to cause administering the engineering failure.
The utility model content
The purpose of this utility model is to overcome the problems referred to above that existing check dam exists, and provides a kind of flexibility netted check dam, is subjected to the environmental factor restriction less during the utility model construction, do not need to be provided with separately spillway, reduced construction technology, and drain charge in time, safety is higher.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The netted check dam of a kind of flexibility is characterized in that: comprise the flexible anti protecting wire net, be provided with supporting rope around the edge of described protective screening, be connected with the anchor pole that is used for fixing protective screening on the supporting rope.
The anti-mask of described protective screening is provided with the multistage supporting rope that is connected with supporting rope.
Described supporting rope is connected in aggregates through sewing up rope with anchor pole with protective screening.
Be connected with Energy eliminating ring respectively on described supporting rope, the multistage supporting rope.
Adopt advantage of the present utility model to be:
One, check dam adopts the flexible anti protecting wire net, not restricted by ambient conditions.
Two, the flexible protective netting gear has the drain charge function, does not need independent spillway is set, and has reduced construction technology and has reduced difficulty of construction.
Three, check dam adopts the flexible anti protecting wire net, and the flexible anti protecting wire net can in time be let out tea to moisture, can not cause dam break because of moisture drain charge in time.
Four, be connected with Energy eliminating ring respectively on supporting rope, multistage supporting rope, absorb the moment impact of alluvial deposit, the protection check dam is not subjected to the damage of moment impact.
Five, be provided with multistage supporting rope, increased the steadiness of check dam.
Description of drawings
Fig. 1 is the utility model structural representation
Be labeled as among the figure: 1, protective screening, 2, supporting rope, 3, anchor pole, 4, the one-level supporting rope, 5, the secondary supporting rope, 6, Energy eliminating ring.
The specific embodiment
The netted check dam of a kind of flexibility comprises flexible anti protecting wire net 1, is provided with supporting rope 2 around the edge of described protective screening 1, is connected with the anchor pole 3 that is used for fixing protective screening on the supporting rope 2.The anti-mask of protective screening 1 is provided with one-level supporting rope 4 and the secondary supporting rope 5 that is connected with supporting rope 2, has improved the steadiness of check dam.And supporting rope 2 is connected in aggregates with anchor pole 3 with protective screening 1 through sewing up rope.Be connected with Energy eliminating ring 6 respectively on supporting rope 2, the multistage supporting rope, absorb the moment impact of alluvial deposit, the protection check dam is not subjected to the damage of moment impact.
When adopting the utility model, directly the ditch body edge that mud-rock flow is impacted relies on as the check dam anchoring, select firm hard formation preferably to carry out the construction of anchor hole Drilling in the basic unit position, if the scene does not have basement rock to expose or when being difficult to find firm hard formation to carry out anchor bolt construction, can locally consider to carry out embedded anchor bar and pour into basic concrete, anchor pole 3 adopts the steel strand anchor pole, and in order to improve steadiness, the supporting rope 2 of the anti-mask upper edge of protective screening 1 rises to two.
Obviously; those of ordinary skill in the art is according to technological know-how of being grasped and customary means; according to above said content, can also make the various ways that does not break away from the utility model fundamental technics thought, these pro forma conversion are all within protection domain of the present utility model.
