(5) Installation of decoration ring for excellence creating project: the width of the decoration ring matches the diameter of the pipe, the width of the decoration ring below DN 100 is 20 mm, and the width of the decoration ring within DN 100-dn 150 is 30 mm
.
(2) Hole reservation and casing embedding: when hole is reserved, the hole should be round, and the diameter of hole is 50 mm ~ 100 mm larger than that of casing; the position of embedded casing should be determined by hanging through line
.
(2) Installation of masonry casing: put the casing into the pipe and place it at each hole, fix it with wooden wedge temporarily, make the casing and the pipe concentric, make the casing and the wall flush, fill the gap between the casing and the pipe with asbestos cement, and make the surface smooth and flat
.
(4) The gap between the casing and the pipeline shall be tightly sealed with asbestos cement, and the sealing paste shall be embedded at the upper closure with smooth surface
.
(3) Pipeline installation: adjust the concentricity of pipeline and casing, control the verticality deviation of riser at 2mm / M and the verticality deviation above 5m ≤ 8mm
.
The casing is 1-2 pipe numbers larger than the riser
.
(6) The concrete protective pier with the height of 300 mm is poured around the casing
.
Effect picture of air vent pipe passing through roof (3) process flow of pipe passing through wall (1) method of casing reserved hole (applicable to waterless part) casing production → reserved hole → pipeline and casing installation → casing fixation → casing external plugging → casing internal plugging (2) method of casing embedding (applicable to watery or waterless part) casing production → setting out and positioning → casing embedding → casing cleaning → pipeline installation (1) casing production: the rigid waterproof casing or flexible waterproof casing shall be selected for the casing with water according to the design requirements
.
(2) The position of embedded casing is determined by hanging through line, and both ends of casing are sealed with adhesive tape to avoid blockage and ensure the concrete around casing is dense
.
When the roof through which the pipeline passes is ordinary roof: the height of the air vent pipe sleeve through the roof is 800mm higher than the finished surface of the roof, and the height of the water supply and drainage pipe sleeve through the roof is 300mm higher than the finished surface of the roof; when the roof through which the pipeline passes is covered with soil (planting) roof, the height of the air vent pipe sleeve through the roof is 800mm higher than the covered soil (planting) surface, and the height of the water supply and drainage pipe sleeve through the roof is higher than the covered soil (planting) surface Degree H = 300 mm
.
(7) The decorative ring is installed at the bottom of the casing under the roof of the excellence project
.
(4) Casing sealing: the gap between casing and pipeline shall be sealed tightly with asbestos cement
.
For the production of rigid waterproof casing and flexible waterproof casing, please refer to 02s404-js10-1 and 02s404-js10-2
.
(5) The gap between the casing and the pipeline shall be uniform, the height above the floor shall be consistent, and the exposed casing on the board surface shall be painted black or gray
.
First, the process flow of pipeline through floor slab (1) the method of casing reserved hole (applicable to waterless parts) casing production → setting out and positioning → reserved hole → pipeline and casing installation → casing fixation → casing external plugging → casing internal plugging → casing painting (2) the method of casing pre embedding (applicable to waterless or waterless parts) casing production → setting out and positioning → casing pre embedding → casing cleaning → casing cleaning The main points of construction (1) casing production: cut the casing according to the pipe specification and the thickness of the floor through which it passes
.
The non fire wall can be made of 3mm rubber plate, and the fire-retardant PVC plate should be used if there are fire-proof requirements
.
The casing is 1-2 pipe numbers larger than the pipe, and both ends are flush with the decorative wall
.
The sealant shall be flush with the end face of the casing, and the glue joint shall be uniform
.
(6) Decorative ring is installed at the bottom of the casing under the floor of the excellence project
.
(7) When the pipe is PVC pipe and is designed with fire ring, the fire ring shall be added at the bottom
.
Pipeline through the floor, wall construction is an important process of water supply and drainage and heating engineering, based on graphic examples, this paper analyzes the standard practice, for your reference
.
(4) Casing sealing: the outer sealing of the casing shall be made of micro expanded fine aggregate concrete with the same strength grade as the floor slab, which shall be sealed in two times and inspected by water test; the gap between the casing and the pipeline shall be sealed tightly with asbestos cement, and the grooves with a depth of 20 mm shall be left at the upper and lower openings respectively, and the grooves at the upper and lower openings shall be filled with sealing glue
.
(5) The waterproof layer must be no less than 300 mm high along the casing
.
(3) The verticality deviation of riser shall be controlled at 2mm / m, and the verticality deviation above 5m shall be ≤ 8mm
.
