Abstract
The utility model relates to a grid sand blocking treating device for channels into the sea and relates to the technical field of waterway transportation. The device is simple and reasonable in structure and low in construction cost. When the device is put into use, channel silting can be reduced effectively, and channel flood carrying capacity is unaffected. The device evident in channel silting reducing effect comprises a plurality of transverse nets and longitudinal nets, wherein the transverse nets have functions of blocking and fixing sand and clearing sands with converging flow, and the longitudinal nets block silt brought by overtopping waves and flows and fix beach face silt.
Description
Technical field
The utility model relates to water transport transport science and techonologies field, and particularly a kind of access to sea adopts graticule mesh sediment trapping controlling device, is applicable to the navigation channel that adopts double-leading-dike to administer on most of Muddy Bottoms and sandbank.
Background technology
Harbour is the traffic infrastructure that passes in and out and berth for safety of ship, is the hinge of land and water transportation.The alluvial problem at harbour has become the Focal point and difficult point of each harbour management work in the world, especially be based upon the estuary harbour on Muddy Bottoms and sandbank, its fairway depth is in order to reach airworthiness requirement, need to be safeguarded by a large amount of, the regular engineering of desilting and dredging every year.For example, Jiangsu Province's Sheyang Harbor adopts the way that regulation combines to implement waterway regulation works, builds double-leading-dike, and excavate deep water fairway in the middle of double-leading-dike, and navigation channel first stage of the project design standard is ton one-way track.After navigation channel is built up, there is comparatively serious back-siltation.The technological approaches of domestic and international existing minimizing channel accretion has two: control sand and line.Control is husky, and principal works measure is to lengthen wall, increase wall, lengthens wall and can reduce silt from mouth door inlet, increases wall and can reduce silt and enter navigation channel amount from wall jacking.The R&D institution such as navigation channel, Shanghai designing institute that bears navigation channel design, Task studied lengthening wall, increase the tradition such as wall subtracts silt mode, find DeGrain, and construction costs is high; Meanwhile, increase after wall and also can cause dike head crossing current to strengthen, ships will enjoy access to the ports in impact.Line, principal works measure is in wall, to construct groynes, increases flow dynamic, but is building after groynes, has restrainted original river course narrow, affects flood discharge safety, this scheme is difficult to obtain the agreement of water conservancy administration department.Therefore, all there is significant limitation in traditional technical scheme, be badly in need of a kind of cost reasonable in the waterway engineering of Jiangsu Province's Sheyang Harbor, and effect of sedimentation reduction obviously and not affects the facility product of flood discharge safety.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, provides a kind of access to sea to adopt graticule mesh sediment trapping controlling device.By horizontal net and vertical coordinating of netting, play the effect that sediment trapping fixes the sand on the one hand, play again on the other hand the effect of clearing sands with converging flow, navigation channel effect of sedimentation reduction is obvious.This plant construction cost is low; After coming into operation, can effectively reduce channel accretion, not affect the flood carrying capacity in river course.
The utility model solves the technical scheme that its technical problem adopts: contain horizontal net, vertical net, suspension, stay cord, pile tube, heavy stone, weight, this device is made up of several horizontal nets and vertical net, wherein several horizontal nets are vertically installed in wall inner side, vertical net is set in parallel in wall inner side, and described horizontal net, vertical net are that screen distance is the graticule mesh of 1 millimeter～3 millimeters.
Described graticule mesh top is provided with the suspension for drawing floating graticule mesh, and graticule mesh base is provided with the weight for drawing heavy graticule mesh, and graticule mesh base arranges several heavy stone for fixing graticule mesh, and the navigation channel end of horizontal net arranges pile tube.
Described graticule mesh wire side, periphery are provided with the stay cord for improving grid structure intensity.
The know-why that the utility model adopts is: several horizontal nets perpendicular to wall are laid in the estuary harbour double-leading-dike inner side on Muddy Bottoms and sandbank, propose groynes position and lay several graticule mesh perpendicular to wall, can play sediment trapping, sand fixation, after long-time use, under graticule mesh, by forming certain alluvial, play again the effect of line.Meanwhile, the vertical net be arrangeding in parallel in wall inner side, is equivalent to increase wall, can tackle the coarse sediment that more dike stream brings, and can brokenly get over again the raw wave of dike miscarriage, the interception silt that more dike wave starts; After long-time use, be conducive to beach face silt long, and then improve the clearing sands with converging flow effect in navigation channel.Adopt graticule mesh to replace traditional hydraulic architecture, played the husky effect of control of building the line effect of groynes and increasing wall, and ensured the unimpeded of current, do not affect the flood carrying capacity in river course.
The utility model beneficial effect is: this apparatus structure advantages of simple, construction cost is low, after coming into operation, can effectively reduce channel accretion, does not affect river course flood carrying capacity.The navigation channel effect of sedimentation reduction of this device is obvious, is made up of several horizontal nets and vertical net, and horizontal net has played that sediment trapping fixes the sand and the effect of clearing sands with converging flow; Vertical net has played the interception silt that more dike wave, stream bring, and the effect of fixing beach face silt.
