Description
Technical field
The present invention relates to construction material technical fields, more particularly, to a kind of river levee construction controlled permeability template
Liner.
Background technique
Hydraulic engineering is a kind of favorable to the people engineering, by water conservancy construction, can control the prevalence of river water, while passing through slow setting soil
River levee is built, the intensity of river levee can be improved, reduces the possibility that river levee breaches a dyke, guarantees people life property safety.
Currently, the problem of due to concrete pouring technology, the concrete of building outermost layer (20mm) be usually quality most
Difference.The performance of concrete surface layer decides its durability used.In concreting process, vibrator vibration force and
Under the action of internal pressure, excessive water and air can be collected at concrete surface layer, if can not be discharged, after concrete hardening its
The structure on surface layer can be relatively rough, and porosity is very big, and consolidation compactness is very low, big trachoma and slight crack easily occurs, causes to make
Concrete surface layer can be penetrated easily with harmful substance in the process, internal bar construction and core part are destroyed, to reduce
The use intensity and life-span of concrete.Some researches show that use controllable permeability concrete mould in concreting process
Plate pads (controlled permeability formwork(CPF)), the quality of concrete surface coating can be improved
And the service life.
Summary of the invention
The present invention proposes that one kind is used multiple times, the river levee construction controlled permeability mould with good air-and water-permeable performance
Plate liner.
The technical scheme of the present invention is realized as follows:
A kind of river levee construction controlled permeability form lining, including gasket body, lower fixing piece, gasket body lower section glue
It is stained with lower fixing piece, the lower fixing piece both ends are inlaid with end cap, and the end cap is integrated with lower fixing piece gluing, the end cap
On form drainage hole, hot-melt adhesive paste has a drainpipe on the drainage hole, and the gasket body includes draining air-permeable layer and cement
Particulate barrier, the draining air-permeable layer side are adhesive with cement granules barrier layer, and the draining air-permeable layer other side is adhesive with
Drain supporting layer.
Further, staged boss is formed in the draining pipe outer wall, the staged boss there are twice always.
Further, the lower fixing piece is U-shaped structure, and the catch basin is molded over inside lower fixing piece, the draining
Hole is communicated to bottom in catch basin.
Further, the draining air-permeable layer is made of polypropylene, and the grid of the draining air-permeable layer is square, net
Lattice are having a size of 3.9*3.9mm.
Further, the draining air-permeable layer with a thickness of 1.53mm, the draining supporting layer with a thickness of 1.97mm, institute
State cement granules barrier layer with a thickness of 0.51mm.
Further, hot melt is fixed with outer wear layer on the outside of the draining supporting layer, and the outer wear layer uses glass fibers
Dimension is made, the outer wear layer with a thickness of one millimeter.
Further, the cement granules barrier layer includes outer rove layer of cloth, spun yarn layer of cloth and interior rove layer of cloth, described outer
Rove layer of cloth, spun yarn layer of cloth and interior rove layer of cloth are successively stitched and are woven in together, and the outer rove layer of cloth is all made of geotextiles and is made, institute
Interior rove layer of cloth is stated to be made of non-woven fabrics.
Further, adhesive layer is adhesive on the interior rove layer of cloth outer surface, the adhesive layer is parallel or is vertically arranged,
The draining air-permeable layer is adhesive on adhesive layer.
Using above-mentioned technical proposal, the invention has the benefit that when concrete is after pouring, in vibrating spear vibration and
Under the collective effect of inside concrete pressure, it can control the capillary absorption of permeability form lining draining air-permeable layer to make in addition, mix
Gas and moisture in solidifying soil are rejected to outside template, and cement granules barrier layer makes cement granules be enriched in concrete table
Layer, thus actually decreasing the ratio of mud of concrete surface layer, form lining only excludes excessive water and air, will not generate true
Empty effect, moisture are discharged by gravity, form ideal W/C ratio in the 20mm of coating, the hydration of such cement is made
With faster more completely, stomatal limiting value is less, and the cement of higher concentration and powder is as a result made to reduce the shape of surface pores and stomata
At, so that obtaining is tighter closeer also more longlasting concrete surface layer, concrete surface layer intensity is improved, permeability is reduced,
To mention the durability of concrete structure.
