Description
Technical field
What the present invention relates to is a kind of building materials and job practices of technical field of building construction, specifically is netted place mat of a kind of modular and wash preventing method thereof.
Background technology
Washing away is a kind of disastrous problem that often runs into, and is washed away by the unsettled distortion that causes of scour and fracture, bridge pier as pipeline to cause that bridge collapses etc.Past washes away in order to prevent, usually makes by placing in the current bottom of washing away generation the bamboo cage or the iron cage of cobble are housed, or directly place boulder, directly stops current washing away bed surface.Yet these conventional approach do not reduce at the flow velocity that will protect and prevent to wash away the position, in case bamboo cage or iron cage corrosion failure, or the boulder of placing is flushed away, and prevents the disabler of washing away; In addition, because burying of silt needs the stone amount of input big, the engineering cost height.Therefore, invention prevents that the effective ways of current scour have extremely important national economy and are worth.
Find by prior art documents, middle title of a reigning dynasty ZL98121425.8, notification number: CN1218129, the day for announcing: 1999.06.02, put down in writing a kind of " the protection against erosion member of aouatic structure thing and protection against erosion construction method ", this technology has the protection against erosion member of aouatic structure thing and uses the protection against erosion construction of this protection against erosion member, and this member is by constituting with the lower part: the netting twine line footpath M that makes with braid and the long limit N of mesh satisfy bag that formula 3≤N/M≤20 concern, pass near the mesh this bag peristome annular hoist cable, pass and wear.Have near the mesh of hoist cable mesh and with the rope of tightening of the peristome sealing of bag.This patent weak point is: 1) mechanism that minimizing is washed away is unclear, still belongs to traditional wash preventing method; 2) though this invention can make described works closely contact with bed surface; but; because in the not minimizing of flow velocity that will protect and prevent to wash away the position; described works is washed away by strong current easily; and because constantly washing away of current can cause that described works moves and part is buried in silt; cause the disabler of its erosion control, therefore, need the engineering cost height.
Summary of the invention
The present invention is directed to the prior art above shortcomings, netted place mat of a kind of modular and wash preventing method thereof are provided, be used to prevent washing away of hydraulic structure, riverbank and seabeach protection, implement simply, cost is low, the effect height.
The present invention is achieved by the following technical solutions:
The present invention relates to the netted place mat of a kind of modular, this netted place mat comprises: fabric pad, slide fastener, main push-towing rope rope, Bower Anchor, inferior hawser and inferior anchor, wherein: slide fastener be arranged on every fabric pad around and connect adjacent fabric pad, the two ends of inferior hawser link to each other with fabric pad with inferior anchor respectively, and the two ends of main push-towing rope rope are connected with four jiaos of fabric pad and Bower Anchor respectively.
Described fabric pad is provided with equally distributed mesh, and this mesh gross area and fabric pad total area ratio are more than or equal to 0.3.
Described fabric pad is provided with the artificial floating fiber of mesh area more than 5 times.
The present invention relates to the wash preventing method of the netted place mat of above-mentioned modular; deaden current to the washing away of riverbed or sea bed bed surface by described netted place mat being covered on riverbed or the sea bed bed surface, avoid or reduce the purpose of washing away and being protected thereby reach the zone that is capped.
Described covering is meant: with machinery or manually netted place mat closely is laid on the bed surface that needs protection; one side of artificial floating fiber is towards the water surface; inferior hawser time anchor is placed bed surface; when flow; artificial floating fiber lodges downstream with near the resistance the increase bed surface, reduces near the water velocity of bed surface.
Compared with prior art, the present invention utilizes netted place mat and artificial floating fiber thereof, increases near the roughness of bed surface, reduces local current sand holding ability, intercepts the souring of current to riverbed or sea bed simultaneously.What the present invention can be widely used near pipelines such as the scour protection, near the scour protection the bridge pier, petroleum gas all kinds of hydraulic structures basis crosses the sail across a sea scour protection etc. at scour protection, riverbank and seashore seabeach on basis of river.
