1. Prepare the relevant material,personnel and equipments to the construction site,Pay high attention to the safety protection work,Build protective fence to the roadbed and slope, To prevent
rockfall hurt worker.
2. Foundation treatment Backfill with grit. Level off the foundation,change the foundation with grit at the thickness 30-50cm,The degree of density must be more than 90%,choose the suitable water
longitudinal around 3%. Ascertain the central line and foul line of the culvert.
3. Adopt section construction when operate the corrugated culvert.Use two steel angle advance install on the foundation of original arch culvert as the slideway that move forward the culvert,The
length of steel angle according to the length of culvert.The diameter of the corrugated pipe could be different specification according to the demand of engineering:
Unitary corrugated pipe:
Diameter: 0.5 M--2.5 M
Length of each unit piece: 3 M
Connection: Flange Plate(built in/External) fit together with screw bolt
Assembled corrugated pipe:
Diameter: 3.0 M--8.0 M
The number of structural plate on the circumferential direction:4-15 pcs
Connection of each structural plate:High strength screw bolt.
4. If the length of the culvert less than 30 meter, the width of the two edge between the culvert and the corrugated pipe is more than 80cm,We can push the corrugated pipe to the up side or down
side,after the corrugated pipe take its place,We can begin the constructe of the retainig wall,Backfill all around with grit or gravelly soil,The top constructe with inflatable cement mortar
transfer through high pressure pump.
5. If the length of the culvert more than 30 meter, the width of the two edge between the culvert and the corrugated pipe is less than 80cm,We can push the culvert pipe which length is 3m-6m from
downstream to upstream.The culvert pipe should be fixed after it take its place,constructe the headwall(end wall)on the top,The gap between the pipe to the other side of the culvert should be
warded of with sandbag or mortar rubble,Its width is 50CM,Then backfill.Both the two side fill coarse sand or concreting and tamped with vibrators. The top constructe with inflatable cement
mortar transfer through high pressure pump.
When finished the backfill all around the first culvert pipe,Transport the second culvert pipe to the site,fit the two culvert pipe together by inner flange bilt,the worker can operate amongst
the culvert pipe,and then backfill with the same mothod after connection.In accordance with this order finish all the whole culvert pipe.
