When concrete works length is longer, when needing to arrange multiple movement joint, repeat the above steps 1-6, Colophonium 16 can do
Once irrigate or irrigate for several times.
The swaging die hung out should be cleared up in time, maintain, and stores, in order to recycling.
When being applied to narrower dam body engineering, can select big semiellipse air bag 17, its elongated die cavity can be that both sides are stayed
Go out bigger concrete wall, there are the effect (with reference to Figure 16) strengthening dam body bulk strength, general die cavity both sides concrete walls
Body is more than 20cm.
The skeleton height of the present invention is generally 2.5M, air bag height 2.0M, and each frame film can pour 2.0M concrete wall,
If body of wall is more than 2.0M, after form removal, improve 2.0M, repeat aforementioned construction method, until meeting body of wall height；This red copper sealing piece
It is connected by Site Welding with horizontal sealing piece.
The present invention is not required to concrete soil box, can 20-30 days reduction of erection time；Swaging die can be reused；Can be
The construction of the box dam retaining wall such as checkdam, cistern, can also be used for undergrounds such as subway, culvert, sluice, tunnel, various mixed under water etc.
The construction application of solidifying geotechnique's vertical sealing of journey movement joint, movement joint is the most non-leakage；Use this technology can solve stratum uneven
The deformation joint seepage water problems that even sedimentation causes, or the expanding with heat and contract with cold of concrete component caused because of the change of ambient temperature cause
Deformation joint seepage problem；The movement joint section interface changing of the relative positions because the natural disasters such as earthquake cause, displacement etc. can also be prevented to become
The leakage problems that shape etc. cause.
Above-described is only the preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, it is also possible to make some deformation and improvement, these broadly fall into the present invention
Protection domain.
