Number position；1 fish inlet is arranged in 3# import, is arranged in the sediment outflow gallery partition wall beginning position (fish 1) 0+152.979；4# import is set
1 fish inlet is set, the right sand washing bottom outlet partition wall beginning position (fish 1) 0+270.839 is arranged in.
Fish pass prefabricated panel reaches 75% of design strength or more, can be installed in batches in the unified production of precast plant；
Prefabricated panel is mainly assembled using punching block is dissipated, and wooden model is squeegeeed；Reinforcing bar makes in processing factory, then is transported to precast plant's binding；Prefabricated bottom
Board concrete is fed by batching plant, and dump truck transport is manually put in storage, and each prefabricated panel one-time-concreting is completed, using φ 70
Or 50 flexible axle vibrating spear of φ sufficiently vibrates；Prefabricated panel and the faying face of cast-in-place concrete need dabbing to handle；Concreting
After completing 12~18h, watering covering curing at moisture-retention and heat-insulation is taken in time, and concrete continuous curing time is no less than 28 days.It is prefabricated
The transhipment of bottom plate and hoist controlling are as follows:
(1) it stacks: stacking that levelling of the land is solid, and component must not stack the damage for causing concrete component, it is ensured that stack surely
It is fixed.
(2) transport: the intensity of precast concrete reaches 75% or more of design strength standard value, just can to component into
Luggage fortune, handles with care when unloading, prevents clashing and breaking；
(3) surveying setting-out: before lifting, survey crew releases the center of elevation, the center line of structure, support to supporting platform seat
The end line and sideline of line and prefabricated panel, and it is clear with the line of ink marker or red paint mark.
(4) interim prefabricated place setting: in view of the transfer of prefabricated panel is difficult, it is arranged on the platform of tailwater channel outlet
The one interim prefabricated place of fish pass bottom plate, facilitates transhipment and installation.
(5) handling: tail water gate pier section fish pass bottom plate uses the handling of 260t crane and installation, when installation component, concrete
Intensity is not less than design strength requirement, is lifted in strict accordance with Hoisting Program, and special messenger takes charge, using steel plate as support
Backing plate；Slowly slow play is played when lifting, slowly in place, the angle in hoist rope and modular level face is not less than 45 °；It is done before lifting
Good temperature pier measure, avoids prefabricated panel from deforming, prevents crack and damage.
(6) it inspects for acceptance: after being installed, special messenger being sent to check support and component, check that support whether there is or not hanging, is taken
Whether spreading degree is enough；It checks whether component surface has cracking or abnormal conditions, and carries out relative recording.
After prefabricated panel installation is in place, then end seam second stage concrete is poured, finally founds steel form again and pour fish pass side
Wall concrete, side wall concrete mainly use carvel built, layer thickness 50cm；If have coarse aggregate accumulation in storehouse, it will accumulate
Aggregate uniformly dissipate paving to mortar compared with many places, in order to avoid cause internal cellular；It is put in storage using extension skin cylinder or automotive pump under sleeping tank；It is mixed
Solidifying soil is vibrated using φ 70 or 50 vibrating spear of φ in time after closing a position, and vibrating spear and prefabricated panel edge keep 5~10cm's
Distance, preventing prefabricated panel from being vibrated influences and deforms；Concrete multiple spot blanking prevents blanking is too fast from causing to run mould.
The prefabricated fish pass slot of this engineering tail water gate pier section bottom plate is mainly supported by adding the pattern of bracket, prefabricated panel
A height of 1.4m, the cast-in-place structural of a height of 3.6~5.7m of abutment wall, the fish pass a length of 8.43m, clear span 2.4m, clear height is 4.4~
6.5m, single prefabricated panel weigh 65.75t, amount to 12 fish pass prefabricated panels.
The present embodiment solves that the multi-span long range fish pass cast-in-place concrete construction period is long, circulation material investment is more, applies
Work problem at high cost ensures construction quality in the process, improves construction efficiency, accelerates construction speed, is hiding the wooden water power
It stands and has played great economic benefit in fish pass engineering construction, provide reliable construction experience for successive projects.
