Description
Technical field
The invention belongs to water conservancy technical field of civil engineering, be specifically related to a kind of flexible erosion control protection pad and construction method thereof for protections such as riverbank, the bed end, pipelines.
Background technology
In water conservancy civil engineering construction, conventionally adopt the form of shore protection or river bottom protection to protect Channel slope, open channel side slope and base slope, pier footing, water-bed pipeline etc., to prevent erosion and current scour.
Conventional shore protection or river bottom protection mainly adopts precast concrete at present, to meet the requirement of subaqueous construction, rapid construction.But the erosion control engineering retrieving at present still has many deficiencies.
On February 4th, 2003, U.S. Kennedy L McAleese top grade people discloses a kind of Revetment block (application number: 03805623.2) that is used to form the revetment of connection, this Revetment block has first and second sections and the first and second sidewalls, this sidewall has the first lower vertical surface, the first and second upper vertical surface and the transitional surface between the vertical surface of upper and lower, this sidewall has been determined interlock, this interlock is protruding from sidewall, and perpendicular to upper vertical surface or angled with this upper vertical surface.This invention has and prevents vertical upper top waterpower and prevent longitudinally the interlocking character with horizontal direction motion.
On October 31st, 2005, Cheng Weiguo discloses a kind of construction method (application number: 200510117472.6) of putting the mask system of washing away, this system fragment of brick used and this system, the some identical fragment of brick that this mask system is connected by rope forms, individual fragment of brick is provided with two rope holes parallel with side, and be equipped with boss and groove on fragment of brick with on the perpendicular dual-side in this amount rope hole, mutual dislocation interlock between adjacent two fragments of brick, makes this mask system more firm.
On July 24th, 2012, the Chen Da of Hohai University etc. has proposed the steel concrete mattress sinking structure (application number: 201220359917.7) of a kind of pre-buried grass-seed, this mattress sinking structure comprises the straight masonry of concrete slab, quadrature and the capsule particle of pre-buried grass-seed, by plantation vegetation, resist extraneous flow dynamic factor and make River Embankment exempt from the problem of erosion damage, improved short silt ability.
Mutual occlusion structure between the block that above patent adopts or integral prefabricated structure, all limited greatly the ability of fender system adaptive deformation, be only applicable to more smooth domaticly, and easily cause the mutual extrusion and collision between block in construction, thereby increase wearing and tearing.The patent of the U.S. (application number: US6579038B1) also have similar shortcoming.
On July 8th, 2011, the people such as Zhu Yijun propose a kind of flexible anti-erosion surface protection system and construction method (application number: 201110192527.5) thereof, the block layer that this mask system is arranged in parallel by some layers forms, upper and lower block layer interconnects by the rope wearing wherein, sets up flexible dumpling isolation and bring the lateral oscillation between constraint fragment of brick between adjacent two layers fragment of brick.This invention is higher with the compatibility that riverbed foundation deformation is coordinated, and is applicable to the domatic of complicated earth surface.But this mask system is very high to the material requirements of flexible dumpling isolation strip, and cost is larger, the horizontal degree of freedom of whole mask system also will be restricted, and not too adapt to the situation that lateral deformation is larger.
In February, 1998, the Thomas M. Angel etc. of the 17， U.S. disclosed a kind of mask system for the protection of water-bed pipeline etc., and this mask is mainly comprised of some reverse docking bucking ladders that connect by rope.This invention realizes and to flexibly connect by itself protecting the corner cut of piece monomer, and horizontal and vertical all have a larger degree of freedom.But this invention does not relate to any grappling measure, once larger impulsive force causes throwing of structure, can cause the destruction of total.Therefore it is necessary, proposing a kind of protection pad that effectively prevents that complex-terrain from washing away and durability is high.
