Embodiment
Embodiments of the invention are described below in detail, wherein same or similar label represents same or like from beginning to end
Element or element with same or like function.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to
For explaining the present invention, and it is not considered as limiting the invention.
River course according to embodiments of the present invention or construction cofferdam bank protection and construction method described with reference to the accompanying drawings.Fig. 1-
2 be the river course of the embodiment of the present invention or the structural representation of construction cofferdam (filling cofferdam) bank protection, and it is a kind of Novel slope protection knot
Structure, including upper strata geotextiles 1, lower floor's geotextiles 5, the filling bed of material and connection lacing wire 6.
Lower floor's geotextiles 5 be laid on former river levee or fill cofferdam 9 it is domatic on, lower floor's geotextiles 5 provided with filling the bed of material,
Fill the bed of material and can select the materials such as antiseepage, erosion control, for substituting the inserts of mould bag in the prior art.Filling bed of material upper berth is provided with
Some connection lacing wires 6 that pass through of upper strata geotextiles 1, upper strata geotextiles 1 and lower floor's geotextiles 5 connect formation entirety.Upper strata geotechnique
The upper end of cloth 1 and lower floor's geotextiles 5 is fixed at the top of bank protection body, and the lower end of upper strata geotextiles 1 and lower floor's geotextiles 5 extends to shield
Slopes bottom, upper strata geotextiles 1 are extended to extend outwardly one section behind bank protection body bottom, so as to strengthen the effect of protection.
As an example of the present embodiment, the filling bed of material includes the loam layer 4 of lower floor and the sand bed of material on upper strata
3.Because the bank protection of the present embodiment is overall using upper and lower layer geotextiles 1,5 and the connection connection formation of lacing wire 6, to prevent inserts
May between upper and lower layer geotechnique 1,5 slide downward, lower floor loam layer 4 both played antiseepage effect, can also after construction with even
Connect lacing wire 6 to bond together, so as to prevent it from gliding.And the sand bed of material 3 on upper strata plays a part of erosion control, wave resistance, Neng Goufang
Only destruction of the external force to loam layer 4, it is ensured that loam layer 4 is not destroyed with being connected the adhesive structure of lacing wire 6.Advantageously, upper and lower layer
Connection lacing wire 6 is equipped between geotextiles 1,5 from top to bottom, if the sand bed of material 3 of so upper part on upper strata glides, can be increased
The thickness of bottom sub-sand earth material layer 3, and connect lacing wire 6 and keep the thickness between upper and lower layer geotextiles 1,5 constant, so that favorably
Glided in preventing the sand bed of material 3.
Further to strengthen being equipped with least one in the fastness of connection lacing wire 6, upper strata geotextiles 1 and lower floor's geotextiles 5
Connection fastener 7 is connected with the horizontal geotextiles reinforcement 2 of bar, geotextiles reinforcement 2, upper and lower layer geotextiles 1,5 pass through connection fastener
7 form overall with the connection connection of lacing wire 6.In addition, geotextiles reinforcement 2 is laterally located in upper and lower layer geotextiles 1,5, be conducive to preventing
Only the sand bed of material 3 glides.
As a specific example of the present embodiment, one layer of prefabricating coping block 8, prefabricating coping block 8 are placed at the top of bank protection body
The upper end of upper strata geotextiles 1 and lower floor's geotextiles 5 is pressed in, prevents geotextiles from sliding.
The river course of the present embodiment or the construction method of construction cofferdam bank protection, step are as follows：
As requested, first the domatic top layer in former river course or construction cofferdam is compacted, leveling is handled, and treats river course or cofferdam
The gradient reach after requirement (referring to the requirement in river course or cofferdam, the requirement of non-slope protection construction), lay at an upper portion thereof lower floor geotechnique
The connection lower end of lacing wire 6, is now fixed together by cloth 5 with lower floor geotextiles 5, and is erected with falsework, then in subsoil
The higher slice of work cloth 5 fills loam and the sand bed of material 3, removes falsework, and smooth, compacting is carried out to skin soil layer, connection is drawn
The upper end of muscle 6 and upper strata geotextiles 1 are affixed, and one layer of prefabricating coping block 8 is placed at the top of bank protection body and is beared down on one, prevents geotextiles from sliding,
Complete slope protection construction, you being formed can antiseepage, the Novel slope protection of wave resistance.
Above-mentioned connection fastener 7 can make together with geotextiles, also with glue can be bonded in geotechnique after geotextiles are formed
On cloth reinforcement 2.
Connection lacing wire 6 can add the two ends of tightrope pattern, i.e. tightrope to connect upper and lower layer respectively using in minor diameter polyethylene pipe
Polyethylene pipe is socketed outside geotextiles 5, tightrope.The effect of polyethylene pipe：(1) falsework is erected by polyethylene pipe when constructing,
It is more convenient than the simple tightrope that erects；(2) after constructing, relative to tightrope, polyethylene pipe surface area is big, is bonded with loam layer 4 more firm
Gu；Meanwhile, when the sand bed of material 3 on upper strata geotextiles 1 or upper strata is moved, tightrope movement is driven, and tightrope is set in poly- second
In alkene pipe, influenceed so that the bonding between polyethylene pipe and loam layer 4 is not moved by tightrope；(3) when removing, tightrope and earth
The not direct adhesion of soil layer 4, it is easier to separate geotextiles with loam layer 4.Advantageously, the length of polyethylene pipe is less than the length of tightrope
Degree.Polyethylene pipe is located at loam layer 4, prevents polyethylene pipe from exposing from the sand bed of material 3.
