Description
Technical field
It is more specifically that channel serves as a contrast under water delivery state the present invention relates to Construction for Hydroelectric Project diversion technology field
It builds structure and repairs cofferdam equipment and assembling method dryly.
Background technique
Water diversion project build up operation during, canal for water conveyance is by underground water and canal's moving SEA LEVEL VARIATION, freeze thawing, construction matter
The influence of many factors such as amount, it is possible that the damage of the forms such as concrete lining plate cracks, collapses, anti-floating unstability, influences
To the safe operation of channel.Repairing construction is reduced to for water energy continuously to supply water as far as possible to user for large-sized water transfer project
The influence of power needs to form dry foundation pit using the narrow channel of cofferdam beam under the conditions of not interrupting channel hydraulic pipeline, carries out the dry ground of lining cutting
Repairing construction.
Pattern is gone along with sb. to guard him in cofferdam can generally be divided into two classes, and one kind is gone along with sb. to guard him for slope sticking type, as shown in Figure 1, cofferdam is close to canal
Domatic is at outer cover；One kind is that semi-wrapped style is safeguarded, as shown in Fig. 2, cofferdam arrangement is flat using upstream and downstream transverse cofferdam and longitudinal cofferdam
Face is arranged as " ┗ ┛ " shape, safeguards channel side.
Slope sticking type, which is gone along with sb. to guard him, need to be arranged certain inside support, and larger to the interference of construction, the foundation pit space of formation is smaller, no
Conducive to construction, while the severely deformed situation in cross-section of river canal slope can not be adapted to.
The foundation pit construction space that semi-wrapped style is gone along with sb. to guard him is big, and repair coverage is adaptable, can effectively guarantee side slope repairing quality,
It improves and repairs speed, but the installation location technology in cofferdam requires height, cofferdam nonrecurring cost is also relatively high.Simultaneously for half
It encloses formula and goes along with sb. to guard him form, it is general using conventional cofferdam such as earth rock cofferdam, concrete cofferdam, stone-laying cofferdam, steel sheet-pile cofferdam etc., wherein
Concrete, stone-laying cofferdam are not suitable for constructing under the conditions of water delivery, and not only difficulty is big for formwork erection, dismounting under concrete water, also will affect
Canal lining；Earth rock cofferdam section is larger, it is big to channel hydraulic pipeline capacity, remove residue easily caused in channel siltation,
Pollution water quality takes native environment to influence greatly；And steel sheet-pile cofferdam damages liner structure, closing water-stagnating effect is poor, and is easy
Channel water body is polluted.
That there is also repair abilities and range is relatively limited for existing cofferdam form, is difficult to adapt to different canal cross sections, construction
The problems such as operation is inconvenient, assembly and disassembly are inconvenient and cyclic utilization rate is low.
The existing channel uses trapezoidal cross-section, tunneling boring cast-in-place concrete liner plate.Canal cross section bottom width about 29~
7m, grade of side slope about 2.0~3.5, design head 8m~3.8m.Canal slope concrete lining plate thickness 10cm, canal base concrete lining cutting
Plate thickness 8cm.Because lining concrete is poured using plain concrete, strength grade C20, thinner thickness is easier because of stress
Unevenness generates destruction.Therefore cofferdam weight need to meet liner plate requirement for bearing capacity, while need to take measures to make liner plate top
Construction weight is evenly distributed on liner plate.
