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%, 9% arable land, solves the food problem of the Liao Zhan world 21% population, and vital effect has been brought into play in farmland water conservancy.
In recent years, central authorities adhere to using construction of water conservancy works as the important foundation that ensures agriculture steady progression and national food safety, constantly perfect policies support system, and increasing work in every dynamics, promotes farmland water conservancy and enters new developmental stage.Within 2012, start four provinces and regions, northeast " it is moving that water saving increases wholesale grain store ", but branch canal is below to field, this " last kilometer " is the weakest link of farmland water conservancy, the problems such as ubiquity standard is low, supporting poor, aging in bad repair, benefit decay, farm field irrigation drainage " last kilometer " problem becomes increasingly conspicuous.
The lining canal of farmland water conservancy water delivery mainly contains U-lag and dovetail groove, existing U-lag and dovetail groove two side and bottom size uniform thickness, and 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 vibration 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, entirety is placed under pressing machine, and when production, the vibration of low slump concrete limit is filled on limit, fills after certain altitude, push with pressing machine, then take mould adventitia apart, goods are shifted out to mould and deliver to the maintenance of maintenance district, this auto-processes level and efficiency are low.Simultaneously because goods adopt low slump concrete, receptor site vibration source and fill time effects, goods are suffered exciting force and asynchronism(-nization) everywhere, easily causing that regional area concrete is crossed shakes, owes to shake, and extrudate density is inhomogeneous, surface irregularity, freeze proof, poor durability, quality causes anxiety and poor performance.
Summary of the invention
The object of the invention is the U-lag and the dovetail groove surface irregularity that obtain in order to solve existing preparation method, 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 medium sand of water, the 600～720kg of breeze, the 178～198kg of flyash, the 25～30kg of cement, the 70～80kg of 390～420kg, rubble that 677～718kg specification is 1-2, rubble, the steel fiber of 5～8kg and the admixture of 9.5～10.5kg that 400～450kg specification is 0.5 as raw material;
Two, the raw material taking is joined to stirrer, after stirring, transfer in material distributing machine by heater car, 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 the frequency vibration 2～3min of antiseepage water delivery water tank die with 1000～1500Hz simultaneously, completes the cloth vibratory compaction of concrete material;
Three, the antiseepage water delivery water tank die that is loaded with vibratory compaction concrete water tank is transported in curing kilns, first the at room temperature quiet 1.8～2.2h that stops, then pass through vapour passage, be warming up to 60～68 ℃ with the temperature rise rate of 13～16 ℃/h, keep being cooled to room temperature with the rate of temperature fall of 13～18 ℃/h again after 2.5h, the antiseepage water delivery water tank die that is loaded with maintenance formation of concrete sends out curing kilns;
Four, the antiseepage water delivery water tank die that is loaded with maintenance formation of concrete that sends out curing kilns is carried out to demoulding processing, complete the preparation of canal seepage control water delivery tank.
The present invention adopts floated shaking table to carry out body vibration processing to the concrete material in mould, in order to the exhaust of concrete materials, closely knit and moulding, shaking table is floated shaking table, vibration efficiency energy maximum effect is on water delivery tank goods, make the quality of canal seepage control water delivery tank product even, closely knit, smooth surface, structural mechanical property be good, more than ultimate compression strength reaches 50MPa, concrete parameters reaches C50F300 level, can be according to the size of product in preparation process, regulation and control vibrational frequency and time.Avoid the generation of existing technique because of the vibration uneven phenomenon of localized vibration initiation, the long U of 2000mm (square) the tank weather resistance and the frost resistance that prepare are greatly improved.
