Description
Technical field
The present invention relates to a kind of for farmland water conservancy water delivery U(square) preparation method of type tank.
Background technology
China, to account for the Freshwater resources in the world 6%, the arable land of 9%, solves the food problem accounting for the world 21% population, and farmland water conservancy has played vital effect.
In recent years, central authorities adhere to using construction of water conservancy works as the important foundation ensureing agriculture steady progression and national food security, and continuous perfect policies support system strengthens work in every dynamics, promote farmland water conservancy and enter new developmental stage.Within 2012, start provinces and regions, northeast four " water saving increases wholesale grain store and moves ", but to field, this " last one kilometer " is the weakest link of farmland water conservancy below branch canal, the problems such as low, the supporting difference of ubiquity standard, aging in bad repair, benefit decay, farm field irrigation drainage " last one kilometer " problem becomes increasingly conspicuous.
The lining canal of farmland water conservancy water delivery mainly contains U-lag and dovetail groove, and existing U-lag and dovetail groove two side and bottom size uniform thickness, waste of material, cost is high, and monolithic length only has 500mm, and section floor space is large.Existing production technique generally adopts low slump concrete to vibrate or compression moulding, existing water tank die divides that inner membrance adventitia is vertical to be laid, inner membrance base plate place installs vibrator additional, under entirety is placed in pressing machine, during production, the vibration of low slump concrete limit is filled on limit, after filling certain altitude, extrude with pressing machine, then take mould adventitia apart, goods shifted out mould and delivers to the maintenance of maintenance district, this auto-processes level and efficiency low.Simultaneously because goods adopt low slump concrete, receptor site vibration source and fill time effects, goods everywhere suffered exciting force are different with the time, easily cause regional area concrete to cross to shake, owe to shake, extrudate density is uneven, surface irregularity, freeze proof, poor durability, quality causes anxiety and poor performance.
Summary of the invention
The object of the invention is to solve the U-lag and dovetail groove surface irregularity that existing preparation method obtains, the problem of freeze proof, poor durability, and the preparation method of a kind of U (square) type canal seepage control water delivery tank is provided.
The preparation method of canal seepage control water delivery tank of the present invention realizes according to the following steps:
One, take the cement of 390 ~ 420kg, rubble that the flyash of 70 ~ 80kg, the breeze of 25 ~ 30kg, the water of 178 ~ 198kg, the medium sand of 600 ~ 720kg, 677 ~ 718kg specification are 1-2,400 ~ 450kg specification be that the admixture of the rubble of 0.5, the steel fiber of 5 ~ 8kg and 9.5 ~ 10.5kg is as raw material;
Two, the raw material taken is joined stirrer, transfer in material distributing machine by heater car after stirring, antiseepage water delivery water tank die is placed on shaking table, by the deflector chute in material distributing machine, raw material is poured in antiseepage water delivery water tank die, shaking table drives antiseepage water delivery water tank die with the frequency vibration 2 ~ 3min of 1000 ~ 1500Hz simultaneously, completes the cloth vibratory compaction of concrete material;
Three, the antiseepage water delivery water tank die being loaded with vibratory compaction concrete water tank is transported in curing kilns, first at room temperature quietly 1.8 ~ 2.2h is stopped, then vapour passage is passed through, 60 ~ 68 DEG C are warming up to the temperature rise rate of 13 ~ 16 DEG C/h, be cooled to room temperature with the rate of temperature fall of 13 ~ 18 DEG C/h again after keeping 2.5h, the antiseepage water delivery water tank die being loaded with maintenance formation of concrete sends out curing kilns;
Four, demoulding process is carried out to the antiseepage water delivery water tank die being loaded with maintenance formation of concrete sending out curing kilns, complete the preparation of canal seepage control water delivery tank.
The present invention adopts floated shaking table to carry out body vibration process to the concrete material in mould, in order to the exhaust, closely knit and shaping of concrete materials, shaking table is floated shaking table, vibration efficiency energy maximum effect is on water delivery tank goods, make the uniform quality of canal seepage control water delivery tank product, closely knit, smooth surface, structural mechanical property are good, ultimate compression strength reaches more than 50MPa, concrete parameters reaches C50F300 level, can according to the size of product in preparation process, regulation and control vibrational frequency and time.Avoid the generation of the vibration uneven phenomenon that existing technique causes because of localized vibration, the long U of 2000mm (square) the tank weather resistance for preparing and frost resistance are greatly improved.
