Specific embodiment
The present invention is further elaborated referring to Fig.1, waterstop installation in buried steel side is reinforced in a kind of short abutment wall in tunnel
Method includes the following steps：
S1. anchor bar 9 is arranged in the position on the first branch face at tunnel both ends and apart from 1~2 meter of 11 end of inverted arch；
S2. lower layer's reinforcing bar of inverted arch 11 is bound after installation back patch waterstop on the tunnel face Chu Zhi；
S3. the buried steel side waterstop 10 along the short abutment wall length direction placement in tunnel, buried steel side waterstop 10 is close to anchor by
Gu one end of reinforcing bar 9 is clamped with vertical fixture 6, vertical fixture 6 is connect by wirerope 7 with anchor bar 9, and wirerope 7 exists
It is provided with cord holder 8 between vertical fixture 6 and anchor bar 9, cord holder 8 is adjusted, wirerope 7 is tightened, the buried steel side in
Waterstop 10 guarantees under a stretching force along the straight of tunnel direction；
S4. after the top bars for binding inverted arch 11, the installation site absolute altitude of buried steel side waterstop 10 in, using mutual
Horizontal fixture 2, horizontal fixture fixing card 3 and the fixing card hangs muscle 4 of the cooperation length of buried steel side waterstop 10 along tunnel by
Direction is fixed so that in the lower steel plate of buried steel side waterstop 10 be fixed in the altitude range of short abutment wall；
S5. the flatness and absolute altitude of buried steel side waterstop 10 repeat step S3 and S4 if any not being inconsistent in repetition measurement, bury in
The fixation of formula steel side waterstop 10 meets specification and design requirement；
S6. inverted arch concrete is poured, after inverted arch concrete strength is met the requirements, removes horizontal fixture 2, longitudinal fixture 6 and tight
Line device 8 simultaneously gives over to the spare of next ring inverted arch 11；
S7. carry out the reinforcing bar binding of the short abutment wall in tunnel, formwork and pour, so far in the lower half of buried steel side waterstop 10 pour
In short abutment wall.
2 top of horizontal fixture is arranged at intervals with multiple horizontal fixture fixing cards 3, is connected at the top of horizontal fixture fixing card 3
The fixing card hangs muscle 4 of eight words, fixing card hangs muscle 4 are fixed on the exposed steel bar 1 of short abutment wall and inverted arch.Horizontal fixture 2 be
In the 10 symmetrically arranged angle steel in two sides of buried steel side waterstop, horizontal fixture 2 be fixed in the horizontal direction in buried steel side sealing
On upper layer steel plate with 10.Horizontal fixture fixing card 3 is the steel plate at waterstop 10 both ends in buried steel side in being symmetricly set on, two pieces
