Abstract
The invention discloses a caisson type washroom water leakage preventing-draining construction method. The method includes using cement mortar to form a screed leveling layer inclined to the wall corner pipe root part, and arcing an internal; coating polyurethane waterproof coating on the leveling layer, and raising by the height of 250 to 350mm along a vertical face; after a water storage text is qualified, forming a water guide hole at the wall corner vent pipe root part to drain the stored water, wrapping a cycle of a stainless steel mesh or fiber mesh outside the water guide hole for preventing the water guide hole from blocking, and using a cement foaming plate to cover a polyurethane waterproof layer as a protective layer; mounting sanitary ware, backfilling slags, and pouring fine concrete below the ground elevation by 45 to 55mm after tamping; coating the polyurethane waterproof coating for the second time after the surface of the fine concrete dries, performing ground surface construction, and performing a second water storage test. A hole is formed at the vertical draining pipe root, even though the bottom of the 'caisson' is provided with stored water, the water can be drained through the hole timely, prevention and drainage can be both considered, and the quality is reliable.
Description
Technical field
The invention belongs to technical field of building construction is and in particular to a kind of caisson type toilet construction method.
Background technology
The commonly used sunk type stringing of residence toilet (referred to as " caisson ") at present, area occupied very little, economic and practical,
But, just in case having pipe burst or joint, loosely the aspect problem such as leak or accomodation ground infiltration occurs, and must pry open ground
Face brick could solve, and being exactly secondly middle packed layer time length can gradually sink, cement mortar screeding layer above, waterproof
Layer, microlith concrete cover will have crack, and accomodation ground water will drain to the region of filling.Because have waterproof layer below again,
Water temporarily will not seepage, result just accumulates in packed layer, time length, and whole packed layer is just filled with water, and sinking casing will
Become sewage plash, be equivalent to and be filled with water always with wooden barrel, even if construction of waterproof layer quality is very well, finally, over time
Extend, substantial amounts of hydrops also can gush and go out.Therefore, how to prevent from excluding the pass that " caisson " hydrops are subsided rest room constructions
Key.
Content of the invention
It is an object of the invention to provide a kind of antiseep effect is good, easy construction, low cost toilet leak is prevented, row
Take into account construction method.
For reaching above-mentioned purpose, as follows using technical scheme:
Caisson type toilet leak is prevented, row takes into account construction method, comprises the following steps:
1) do hole bottom screed-coat with cement mortar, screed-coat tilts to corner pipe root position, and inner corner trim smears circular arc；
2) screed-coat brushing polyurethane water-proof paint, returns 250-350mm height, above wall tile position changes along along facade
For js cementitious composite water-repellent paint；
3) convince water hole by patient analysis in corner breather root position after water-storing test is qualified, drain water-retention, water-guiding hole dresses outside a circle
Stainless (steel) wire or fleece, then cover polyurethane water-proof layer as protecting insulating layer with cement foam board；
4) sanitary ware is installed, slag backfill is done on cement foam board, pour after tamping and smash pea gravel concreten to ground mark
High following 45-55mm；
5) brush second time polyurethane water-proof paint after pea gravel concreten dry tack free, then carry out ground surface construction,
After the completion of carry out second water-storing test.
By such scheme, described caisson type toilet leak is prevented, row takes into account construction method, step 2) in brushing polyurethane
During water-repellent paint, 300mm height is returned along along facade.
By such scheme, described caisson type toilet leak is prevented, row takes into account construction method, step 4) tamp after pour smash thin
Stone concrete 50mm to ground elevation.
Beneficial effects of the present invention are mainly:
Toilet warterproof is pressed design requirement and is constructed, simultaneously in soil stack root perforate, even if hydrops are arranged at " caisson " bottom,
Also can exclude from osseotomy site in time, reach that " anti-, row " is simultaneous to apply, reliable in quality；Replace cement with live waste and old cement foam board
Polyurethane water-proof protective layer made by mortar, has both prevented the destruction to waterproof layer for the cement mortar laying task, reduces percolating water hidden danger,
Can be salvaged again, greatly reduce construction cost, and smearing cement mortar protective course operation, to be changed to paving cement foamed
Plate operation, without increasing material and instrument, easy construction outside increment, improves economic benefit；
Specific embodiment
Following examples explain technical scheme further, but not as limiting the scope of the invention.
Caisson type toilet leak is prevented, row takes into account construction method, and process is as follows:
1) caisson of toilet base cleaning is clean, watering moistening and must not obvious hydrops, make of 1:2 cement mortar and cheat bottom and look for
Flat, to corner pipe root position, inner corner trim smears circular arc to the slightly gradient, and sanitary equipment drain pipe port is blocked with Polypropylence Sheet, in case debris blocking row
Water pipe.The reserved fixed gap in pipe root position is not levelling, is filled into round pier shape with cement based sealing agent.
2) screed-coat brushing polyurethane water-proof paint, for avoiding capillary attraction water and the aqueous vapor in drying structure, leads to
Wall is walked or penetrated to water toward eminence, and the part leakage never doing waterproof is gone out, and urethane water-repellent paint returns 250- along along facade
350mm height, above wall tile position is changed to js cementitious composite water-repellent paint.In order to avoid impact wall brick adhesive strength.
3) convince water hole by patient analysis in corner breather root position after water-retention 24h pass the test, to drain water-retention, for preventing water-guiding hole
Blocking, water-guiding hole dresses outside a circle stainless (steel) wire or fleece, then covers polyurethane water-proof layer as guarantor with cement foam board
Shield sealing coat.For preventing waterproof coating from destroying, do protecting insulating layer using live old cement foam board, replace cement mortar protection
Layer, had both prevented the destruction to waterproof layer for the cement mortar laying task, reduces percolating water hidden danger, can be salvaged, significantly again
Reduce construction cost, and cement mortar protective course operation will be smeared and be changed to paving cement foam board operation, without increasing outside increment
Plus material and instrument, easy construction, improve economic benefit；
4) sanitary ware is installed, slag backfill is done on cement foam board, pour after tamping and smash pea gravel concreten to ground mark
High following 45-55mm.Cement foam board between packed layer and polyurethane water-proof layer plays insulation blocking effect, in case backfill is sharp
Thing scratches waterproof coating, it is to avoid waterproof layer lost efficacy.
5) brush second time polyurethane water-proof paint after pea gravel concreten dry tack free, then carry out ground surface construction,
After the completion of carry out second water-storing test.
Repeat such scheme, step 2) in brushing polyurethane water-proof paint when, return along along facade 300mm height.On repeating
State scheme, step 4) tamp after pour and smash pea gravel concreten 50mm to ground elevation.For preventing toilet water from flowing backwards, toilet
Design ground is generally below other room floors 50mm.
