Hold it is agglomerating preferably；
（6）After mortar joint condenses, the space on backfill prefabricated component both sides, compacting, remaining earth material etc. is transported out of.
The protrusion substantive distinguishing features and significant progress that the present invention has relative to prior art：
1st, the present invention can make small-sized water channel meet that batch production is produced in enormous quantities, carry out mechanized construction at the construction field (site), compared with
It is big to shorten the engineering construction duration, ensure construction quality.Its is firm in structure, and anti-extrusion deformation is strong, convenient disassembly, can repeat profit
With Butt sealing is good, and appearance is neat, and streamline is attractive in appearance, and installation is quick, and it is convenient to remove.
2nd, construction efficiency can be greatly improved in the present invention, improve more than 7 times than common construction method, the construction period shorten to
80~90%.
3rd, materials needed for present invention production are few, can save cast-in-place concrete investment 12~35%, larger to reduce cost throwing
Enter, great economic interests can be produced.
4th, the mould of production and application of the present invention, its making is simple and convenient, and assembling is quick, and process simplifies, and modulus, is convenient in demoulding
Quickly；And the bar construction being equipped with component so that the structure of gool prefabricated component is firmer, and resistance to compression and tensile capacity increase
By force；The principal rod and construction muscle that bar construction frame is set make whole gool structure stress reasonable, can resist external force and component is broken
It is bad.
5th, the concrete coarse aggregate that uses of the present invention is for limestone or granite, and particle diameter is 5~30mm, coarse sand for 1~
5mm, using the concrete of C20 labels, grading is 2 grades, to the less demanding of raw material, is adapted to wide geographic area to use.
6. framework of steel reinforcement design of the present invention is special, it can ensure that small-sized water channel is not easy seepage, it is sturdy and durable, compared with existing
Water conservancy Channel Quality improve more than 4 times.
7th, precast concrete produced by the invention is provided with U-shaped docking groove in joint, and U-shaped abutment joint is formed after connection,
Concrete is filled up in seam（Or impervious viscous and material）, the loss of water-carrying capacity can be greatly reduced, substantially increases water use efficiency；
Meanwhile this U-shaped abutment joint protects prefabricated component not to install the water channel of prefabricated component because cold and hot deform provides the variable space
It is damaged.
8th, the water channel prefabricated component after casting concrete of the present invention conserves at the scene, after temperature is more than 500h DEG C during maintenance
Removable side mould, removable die cavity after temperature is more than 1500h DEG C during watering maintenance, prefabricated component, which is concentrated, after form removal chamber stacks, and conserves
Can dispatch from the factory use during more than Shi Wenda 2000h DEG C；This kind of maintenance method is taken, can reach accurate to water channel prefabricated component
Maintenance, the quality of water channel prefabricated component is improved, strengthen the resistance to compression of water channel prefabricated component and tensile capacity；It can also save unnecessary artificial
Input, the unnecessary waste of water is also avoided that, reduces production cost.
9th, reinforcement constitution of the present invention include second layer distributing bar, first layer distributing bar, reinforcement distributing bar and
Longitudinal reinforcement, the second layer distributing bar, first layer distributing bar and reinforcement distributing bar connect and compose unit member, and first
Second layer distributing bar is sandwiched in centre by layer distributing bar and reinforcement distributing bar, and several unit members are connected by longitudinal reinforcement
It is connected into reinforcement constitution.This reinforcement constitution design is special, can ensure that water channel prefabricated component is sturdy and durable, pre- compared with existing water channel
Parts quality improves more than several times, can be through under pressure indeformable.
