Water-permeable frame is prepared with the method, possesses that making is simple, can improve efficiency of construction, cost-effective advantage.
The technical solution adopted in the present invention is：
A kind of steel fiber reinforced concrete structure water-permeable frame, cancels original water-permeable frame bar construction, straight using steel fiber reinforced concrete
Connect pre-formed, the steel fibre include the waveform steel fibre of random distribution or pressure rib type steel fibre.
The waveform length of steel fiber is more than or equal to 3cm, with diameter greater than equal to 0.4cm；Pressure rib type length of steel fiber is more than
5cm is equal to, with diameter greater than equal to 0.2cm.
A kind of steel fiber reinforced concrete structure water-permeable frame method for prefabricating, comprises the following steps：
Step 1：By the steel fibre that selectes by the match ratio of design, mix in concrete；
Step 2：Steel fiber reinforced concrete mixes and stirs technique using wet after first doing；
Step 3：Steel fiber reinforced concrete carries out vibrating pouring；
Step 4：The molding early stage of steel fiber reinforced concrete component is conserved in maintenance area, after certain intensity to be achieved, is removed to heap
Concentrate and stack in field.
In the step 2, feeding sequence is：
Coarse aggregate → steel fibre → fine aggregate → cement；
Wherein steel fibre is added in mixer in three times when mixing and stirring, and adds steel fibre when mixing；
Pour yellow ground, cement again into, 2min～3min is mixed and stirred again after all material inputs, finally fill up water wet-mixing 1min；Always mix and stir
Time is less than 6 minutes；
During mixing and stirring, steel fibre, cement, sand, rubble strictly press match ratio parameter, and the amount for often feeding intake once adopts quantifier
Strict measurement.
A kind of steel fiber reinforced concrete structure water-permeable frame method for prefabricating of the present invention, advantage are：
1：Steel fiber reinforced concrete, is mix in normal concrete that the short steel fibre of random distribution formed a kind of new many
Phase composite materials.The steel fibre of these random distributions can effectively hinder extension and the macrocrack of inside concrete microcrack
Formation, significantly improve tension, bending resistance, shock resistance and the anti-fatigue performance of concrete, with preferable ductility and rigidity.
2：Xoncrete structure water-permeable frame prepared by the method, makes simple, improves efficiency of construction, cost-effective, be with
Previous experiments research is done using machine pressure batch production water-permeable frame afterwards.

Specific embodiment
A kind of steel fiber reinforced concrete structure water-permeable frame, cancels original water-permeable frame bar construction, in water-permeable frame coagulation
The steel fibre of random distribution is mixed in soil structure, and directly pre-formed, the steel fibre can adopt the waveform steel of random distribution fine
Dimension, may also be employed pressing rib type steel fibre.
Limited by water-permeable frame dimensional structure and be easy to steel fiber reinforced concrete stirring to need, the waveform steel fibre is preferably adopted
It is more than or equal to 3cm with length, with diameter greater than equal to 0.4cm；Pressure rib type length of steel fiber is more than or equal to 5cm, with diameter greater than being equal to
0.2cm.
Make comprising the following steps that for this steel fiber reinforced concrete structure water-permeable frame：
1), preparation of construction, is cleaned to mould before assembling, in die inside brush releasing agent.
2), place cleaning, the concrete disintegrating slag and debris in place is cleaned out.
3), mould assembling, three lamellar modules are put in three sides of framework of steel reinforcement, two-by-two splicing alignment, and are entered by screw rod
Row is fixed.Again the mould for having fixed is stood upside down, internal model alignment is put in the middle of handstand mould, and is passed through rotatable buckle
It is fixed.
4), waveform steel fibre or pressure rib type steel fibre reinforcement fabrication concrete permeable framework as an alternative is selected.
5), the comprcssive strength requirement that selectes by detail design, the steel fibre that selectes, cement, yellow sand, rubble are set by construction
The match ratio of meter carries out ginseng and matches somebody with somebody.There are various strength criterion match ratios when steel fibre is purchased, also can be former by steel fiber reinforced concrete
Cai Song testing laboratories carry out mix-design.
6), concrete-agitating, for preventing steel fiber reinforced concrete fibrous caking in stirring, in construction, often stirs once
Amount of agitation be not more than the specified amount of agitation of blender 80%.Mixed and stirred using drum mixer, steel fibre is made in whipping process
It is uniformly distributed.For ensureing the mixing quality of concrete mixture, technique is mixed and stirred using wet after first doing.When feeding sequence and stirring
Between be：Coarse aggregate（Rubble）→ steel fibre（Dry mixing 1min）→ fine aggregate（Yellow sand）→ cement（Dry mixing 1min）, wherein steel fibre
Added in mixer in three times when mixing and stirring, steel fibre is added when mixing, then pours yellow ground, cement into, after all material inputs, then
2min～3min is mixed and stirred, water wet-mixing 1min is finally filled up.Total mixing time is less than 6 minutes, by the steel fibre that this program is mixed out
Compound uniform.
During mixing and stirring, steel fibre, cement, yellow sand, rubble should strictly press match ratio parameter, and the amount for often feeding intake once should
Use quantifier strict measurement.
7), vibrate and pour, the mould for assembling is stood upside down in the smooth hardening precasting yard for being covered with thin film on the ground, vibrator is put
In vibrating on platform in the middle of internal model, then the concrete material being stirred is poured in mould, while opening vibrator, shaken when filling
Smash, due to steel fiber reinforced concrete mix vibration compacting degree than portland cement concrete mix vibration compacting degree greatly, so
Vibrating time is longer.
8), the age of steel fiber reinforced concrete component is 28 days.Conserving in area within 3 days before the molding of steel fiber reinforced concrete component
Maintenance, after certain intensity to be achieved, removes to concentrate to stockyard and stacks, while carrying out maintenance, prevents concrete dehydration, cold injury, curing period
Minimum is 7 days.Steel fiber reinforced concrete is using watering maintenance.
