Description
Technical field
The present invention relates to the constructions of cavern's lining concrete, and in particular to a kind of hydraulic mobile jumbo of Varied section and operation side
Method.
Background technique
White crane beach power station flood Discharge tunnel Project mainly includes 3 flood discharging tunnels, and every flood discharging tunnel is by inlet transition, upper flat
Section, dragon fall endpiece composition.Dragon falls tail and is made of wet odd curved section, slope section and ogee section.Wet surprise curve mode is Z=X2/500+
0.015X, slope section are the connection changeover portion between wet odd curve and anti-arc, 1# and 2# flood discharging tunnel ramp slope 1:4,3# flood discharge
Hole ramp slope is that 1:3.72. ogee section is located at slope section downstream, anti-arc radius 300m.The anti-arc of 1#, 2# flood discharging tunnel directly connects
Defrlector bucket, 3# flood discharging tunnel are limited between anti-arc end and bucket lip by orographic condition and increase flat section under one section, lower flat section bottom
Slope 8%.
Every dragon of flood discharging tunnel falls tail and arranges 3 aerators, and aerator position is sudden expansion structure, and it is disconnected to share 7 kinds of lining cutting
Face,.Wet odd curved section is connect before flood discharging tunnel 1# aerator, is followed by slope section, bottom board slope is changed to 1:4.52 by 1:4 after lining,
The crown gradient is changed to 1:3.7216 by 1:4, since to become slope pile No. inconsistent for crown and bottom plate, cause flow section height by
18m is raised to 19.61m, is changing into linear distribution.Flow section width is by 15m, mutation to 15.7m, unilateral side amplification 35cm.
Flood discharging tunnel 2# aerator is located in the middle part of slope section, and bottom board slope is 1:3.7216 after lining, and the crown gradient is by 1:
3.7216 are changed to 1:2.45, since crown and bottom plate change slope pile No. are inconsistent, flow section height are caused to be raised to by 18m
19.50m being changing into linear distribution.Flow section width is by 15.7m, mutation to 16.2m, unilateral side amplification 25cm.
Reversed segmental arc before flood discharging tunnel 3# aerator is followed by lower flat section, and bottom board slope is 8% after lining, and the crown gradient is become by 8%
Change to 1:4.83, since crown and bottom plate change slope pile No. are inconsistent, cause flow section height to be raised to 19.5m by 18m, change
Linear distribution.Flow section width is by 16.2m, mutation to 16.5m, unilateral side amplification 15cm.
According to previous experiences, China hydroelectric project flood discharging tunnel dragon falls tail concrete construction generally using more set trolleys, difference
Working face starts concrete construction simultaneously, and each working face lining trolley size is inconsistent；Lining trolley is generally by volume
Machine travel walking is raised, each lining section arranges a lining trolley, then equipment cost is excessively high, and trolley walking utilizes elevator
