Step 1, on request blanking, make the size of each component of access path, then make sense channel；
Step 2, mounted access path was sunk in water aqueduct, and be installed on the position of expansion joint water stop；
Step 3, the water in access path cavity is extracted out, while by pressurised airbag inflating pressure, using access path outside
Portion's effect of water pressure will be pressurizeed between channel-section steel and aqueduct side wall and aqueduct bottom plate and be compressed, and flexible waterproof material is by pressurised airbag with crossing
Gap is filled up completely between groove sidewall and aqueduct bottom plate, so as to realize the impermeable role between access path and outside water body；
Step 4, after Awaiting Overhaul in-channel water exhausts, change original waterstop；
Step 5, this constructing device is integrally hung out after acceptance(check) after waterstop installation.
Described step one includes following step：
Step 1, make the steel structure framework of access path；
Step 2, the steel structure framework welding of pressurize channel-section steel and access path is integral；
Step 3, the pressurised airbag of unaerated is placed in pressurization channel-section steel；
Step 4, flexible waterproof material and pressurization channel-section steel and pressurised airbag are fixed as entirety.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is provided with access path in aqueduct along the covering of aqueduct expansion joints waterstop, then takes access path away
Water in cavity, while by pressurised airbag inflating pressure；Will pressurization channel-section steel and aqueduct using the effect of access path external water pressure power
Compressed between side wall and aqueduct bottom plate, prevent external water stream from entering in access path so as to effectively seal, be underwater construction
Create the space of a construction.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is elevation of the present invention.
In figure, waterstop 1, access path 2, aqueduct side wall 3, aqueduct bottom plate 4, pressurize channel-section steel 5, pressurised airbag 6, and flexibility is anti-
Water material 7.
