Embodiment
The technical solution of the utility model is elaborated below in conjunction with the accompanying drawings.
A kind of river anti-impact spats, referring to Fig. 1 and Fig. 2, a-quadrant is river, including is laid on the rubble base of river course bottom
Layer 100, and successively it is laid on the geotextiles 101 and alloy-steel network gabion 102 of crushed rock base course more than 100, the alloy-steel network stone
Cage 102 is filled with rubble or cobble；There is flexibility using alloy-steel network gabion 102, can adaptively rush hole shape, formed
Protection pad, prevent punching hole from expanding, jeopardize the stabilization of structures.
The specific alloy-steel network gabion 102 is made of double-layer double-direction construction muscle, and double-layer double-direction is two layers of reinforcing bar altogether
Net, it uses a diameter of 10 millimeters of reinforcing bar, is that 200 millimeters of heat bundles form by spacing.
But because the gradient is steeper in mountain channel, through being commonly formed mud-rock flow, the stone below one meter in diameter can roll with current
It is dynamic, alloy-steel network gabion 102 is damaged, in order to prevent stone impact alloy-steel network gabion 102, in alloy-steel network gabion
Increase concrete layer 103 on 102, but 103 each flood of pure concrete layer can all be cut in the thickness more than one centimetre later, mixed
The cobble of the solidifying embedding outwardly convex in the surface of soil layer 103 can effectively prevent washing away for mud-rock flow.Specifically, the concrete layer 103 is thick
Spend for 300 millimeters, and polypropylene anti-crack fiber is blended in concrete layer 103, polypropylene anti-crack fiber is processed through special process
The high intensity pencil monofilament organic fiber for handling and being formed, its intrinsic resistance to strong acid, resistance to highly basic, weak thermal conductivity, have extremely steady
Fixed chemical property.Add in mortar or concrete can effectively control in mortar, concrete the plastic shrinkage stage in the early stage by
Microcrack caused by the factors such as temperature change, prevent and restrain the formation and development in crack, substantially improve concrete resistance split it is anti-
Ooze performance, shock resistance and shock resistance；Be embedded in the surface of concrete layer 103 cobble expose concrete surface height be more than or
Equal to 80 millimeters, preferable height is 100 millimeters.
The river anti-impact spats upper surface forms slope, and the stone rolled along river bed can be allowed effectively to be prevented away from dyke
The friction of stone and metope, protect the metope of both sides.
Embodiment two
The present embodiment provides a kind of river anti-impact dyke, can be applied to a kind of river anti-impact spats two of the offer of embodiment one
Side, as the embodiment for constructing complete river course.In addition, a kind of river anti-impact dyke can also be carried out independently, with up to
To the effect of resistance pluvial erosion.In the present embodiment, illustrated in case of independently carrying out.
Dyke, it is meant that protect dykes and dams, is the both sides metope in river course.
Referring to Fig. 1 and Fig. 3, the river anti-impact dyke includes the concrete floor 200 being connected with the bottom in river course, the coagulation
The height of native bottom plate 200 is 1.8 meters, and the concrete floor 200 is used for the shock for resisting the ratchel of bottom of river channel.
Carried on the top of concrete floor 200 from embedded retaining wall structure.It should include from embedded retaining wall structure in
Bearing course 201, back-up coat 202 and the alien invasion 203 outwards set gradually.
Vertically pile up and form specifically, bearing course 201 is ecology bag, filling cobble in lower floor's ecology bag 210, on
Filling grittiness earth material in layer ecology bag 220；Vertically pile up and form if back-up coat 202 is dried layer GSZ 230, geotechnique
Filling graded broken stone in grid 230, every layer of thickness of GSZ 230 are 500 millimeters；Alien invasion 203 is kept off using from embedded landscape
Cob wall building block 240 is piled up along vertical plane to be formed, and is respectively from the length, width and height of embedded landscape retaining wall block 240 each specifically
400 millimeters, 305 millimeters and 150 millimeters；Hole is provided with from the block top and bottom of embedded landscape retaining wall block 240, up and down
Adjacent layer is connected from embedded landscape retaining wall block 240 by anchoring rods 250, and the both ends of anchoring rods 250 are inserted up and down respectively
Two layers from the hole of embedded landscape retaining wall block 240.
It is overall to river course outer incline from embedded retaining wall structure, specifically, being 12 ° relative to the angle of inclination of vertical plane.
This carries concrete from the upper end of embedded retaining wall structure and bears down on one 260 from embedded retaining wall, and the concrete is from embedded retaining wall
Bear down on one and guardrail 270 is installed on 260.
Concrete bears down on one from embedded retaining wall and 260 the upward portion that arches upward is formed at river course, and direction is provided with the portion that arches upward
The PVC drain pipe 280 through the portion that arches upward that river course tilts down.It is also equipped with dipping down towards river course on concrete floor 200
Oblique PVC drain pipe 280, the PVC drain pipe 280 in concrete floor 200 connect with back-up coat 202.
Concrete bears down on one 260 along every 5 meters of settings, one of the expansion joint of river course bearing of trend from embedded retaining wall, is filled in the flexible cutting edge of a knife or a sword
Ethylene closed cell cystosepiment, ethylene closed cell cystosepiment absorptivity is low, and anti-permeability is good, is laid on concrete and first pours block
The inner side of template, the phenomenon of expanding with heat and contract with cold for compensating concrete.
Above-mentioned river anti-impact dyke bears soil pressure using the Grazing condition enclosed construction of the anti-package ecology bag of GSZ 230
And seismic force, avoid from this solid structure of embedded retaining wall to GSZ 230 because unbalance stress produces local failure, profit
Flood erosion and outside adverse circumstances are resisted from embedded retaining wall with outer lining, such as sharp thing cutting, ultraviolet, fire are to geotechnological lattice
The destruction of grid 230.This structure has the ecological effect of water-permeable and air permeable, can be good at being formed with river course Ecology and circulates benignly.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
