Description
Technical field
The present invention relates to one kind to be used for deep narrow gutter wall continuous placing high density polyethylene (HDPE)（High-density
polyethylene）The nonmetallic horizontal slip-form systems of HDPE, stood for substituting middle-size and small-size gutter construction using the common wooden model of type
Mould pours.Mainly apply to hydraulic engineering field artificial ecology lake periphery depth gutter, intercepting ditch wall formwork erection pours；Farmland water
The quick formwork erection of sharp lining canal, irrigation canal, is also applied for town road and the supporting gutter of traffic engineering is quickly continuously constructed.
Background technology
High density polyethylene (HDPE) High-density polyethylene (HDPE) have good heat resistance and cold resistance,
Chemical stability is good, also has higher rigidity and toughness, and mechanical strength is good, and barrier property, dielectric properties are also preferable, extensively should
For the field such as blow-molded article, film and board product, injection-molded item, tubing article, fiber, electric wire.It is at present the world
The third-largest general-purpose plastics of upper usage amount, is only second to polyvinyl chloride and polypropylene, is that the one kind concerning national economy synthesizes
High polymer material.The country is mainly used in municipal tubing, geomembrane and Seepage field.
Civil Engineering engineering field man-made lake engineering drainage ditch Section Design will also meet function in addition to flow factor is considered
The high range request in property Yield rainfall relation bottom.Man-made lake engineering needs to regularly replace lake region poultry water from holding water body cleaning function angle, it is desirable to
Peripheral gutter will have enough depth, in order to water outlet；And consider to meet that reduction is poured as far as possible on the premise of water flow again
Build concrete square amount.Based on above-mentioned two aspects reason, discharge section form uses deep narrow-structured model.In practice of construction, this
The gutter formwork erection generally use plank sheathing or simple combination punching block of type, in practice in the presence of following defect：
(1) clear span is less than 0.5m deep narrow gutter, and middle internal model formwork erection operating space is very small, can not pass through routine
Upright mould process is constructed；
(2) it is relatively fewer to be used in turn number for plank sheathing, loss in process be present；
(3) during site operation, plank sheathing reinforcement system generally deform it is larger, it is vertical for deep narrow concrete ditch body
Degree is poor；
(4) single-block area is small, splicing seams after form removal between block and block be present, and it is attractive in appearance to influence the big face of concrete；
(5) plank sheathing water absorption rate is big, and thermal insulation is poor.Under the conditions of dry weather, it is possible to cause because concrete surface is inhaled
Water and there is local dew sand phenomenon；It is likely to occur under cold conditions dry and cracked, causes deformation；
(6) common formwork erection needs by form removal, organizes mould, reinforcing process again, and duplication of labour amount is big, and identical quantities needs
More labour, long construction period are put into, work efficiency reduces；
(7) plank sheathing needs to consume ecosystem timber, sheet material, is unfavorable for environmental protection.
Based on this background, research and development one kind is new to be used for deep narrow gutter（Canal）High density polyethylene (HDPE)（High-density
polyethylene）The nonmetallic continuous placing horizontal slip-form systems of HDPE are used to substitute the common plank sheathing of tradition.
The content of the invention
To overcome above mentioned problem, the technical solution adopted by the present invention is as follows：
One kind is used for the deep nonmetallic horizontal slip-form system of narrow gutter wall continuous placing, including unit sliding formwork, unit
Sliding formwork main body is made up of interior plate and outer panel, and fixing strut by adjustable type between interior plate is made positioning, interior plate bottom
Provided with bottom roller axle sleeve, bottom roller；Wire drawing bar is fixed by top at the top of interior plate and outer panel, interior plate and outer panel
Top surface is closed by cover plate pressing plate.
The inner side template includes interior hidden stiffening frame, and interior hidden stiffening frame surface is provided with HDPE double face slabs and exposed vertical
To ribbed stiffener, exposed longitudinal stiffener is provided with adjustable type and fixes strut, adjustable type fixation strut groove, and adjustable type fixes strut groove
Top is provided with top to wire drawing bar groove；Interior hidden stiffening frame both sides are provided with head plate latch preformed hole；Interior hidden stiffening frame bottom
Ditch, which is worn, provided with middle and lower part sells bolt hole to drawing.
The outer panel is identical with inner side harden structure.
Head plate latch preformed hole and adjustable type on the interior hidden stiffening frame are additionally provided with head plate between fixing strut.
The cover plate pressing plate is provided with cover plate pressing plate connection ring, and cover plate pressing plate connection ring reserves cover plate pressure with interior external mold upper end
Plate pin hole is corresponding, and cover plate pressing plate is connected into master module by latch during installation.
The quantity of the interior plate and outer panel is respectively two.
The interior hidden stiffening frame both side surface is equipped with HDPE double face slabs.
The interior hidden stiffening frame is welded to connect with longitudinal stiffener.
Bottom roller axle sleeve forms pulley gear with bottom roller, and material uses ironcasting；Roller surface is handled through finishing,
It can be moved freely in roller axle sleeve axial direction certain space, to meet that peace tears interior modular space needs open.
Advantages of the present invention：
(1) new type formwork bending resistance, shearing strength are high, and deflection deformation is small, and mechanical property has larger excellent compared with common plank sheathing
Gesture；
(2) factory prefabricating processing criterion, seriation are realized, processing loss is small, is used in turn often；
(3) installation and convenient disassembly, formwork erection, form removal workload are largely reduced, improves template service efficiency.It is same in input
Under the labour of sample, same quantities, construction speed, operating efficiency new type formwork are more advantageous；
(4) HDPE materials have corrosion resistance, wear resistance, the use of sliding formwork can be increased substantially using this material
Life-span；
(5) the proportion of HDPE materials is 0.95, compared with big punching block and wooden model, much light.It is equipped with sliding formwork bottom
Roller, manually just can conveniently fast fast movement；
(6) modularization formwork erection is realized, length is poured according to segmentation, is connected with single-unit and completes segmentation formwork erection, when saving installation
Between, artificial and auxiliary material；
(7) panel plate face is smooth, and water retention property is good, is stitched after concrete form removal without template, any surface finish, attractive in appearance；
(8) the design of the structure of double plates and ribs, the integral rigidity and intensity of sliding formwork are added, be applicable to 2~5m depths
The deep gutter of degree pours；
(9) because material has corrosion resistance in itself, for a long time without using the deformation that will not get rusty, it is not necessary to extra maintenance costs；
(10) new sliding formwork saves timber, the secondary of absolute environment is broken using HDPE macromolecule materials substitution wooden model or punching block
It is bad, there is the feature of environmental protection.
