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, be specifically related to a kind of caisson type washroom construction method.
Background technology
The sunk type stringing (being called for short " caisson ") that residence toilet generally adopts at present; area occupied is very little; economic and practical; but; just in case have, pipe burst or joint are not firm to leak or the aspect such as accomodation ground infiltration problem occurs, must pry open floor tile could solve, and the packed layer time in the middle of being exactly has secondly been grown meeting sinking gradually; cement mortar screeding layer above, waterproofing course, fine-stone concrete topping just have crack, and accomodation ground water will drain to the region of filling.Because there is again waterproofing course below, water temporarily can seepage, result just accumulates in packed layer, and the time has been grown, and whole packed layer has just been full of water, sinking casing will become sewage plash, be equivalent to filling water with wooden barrel always, even if construction of waterproof layer quality is fine, final, along with the prolongation of time, a large amount of ponding also can gush and is gone out.Therefore, how to prevent from getting rid of the key that " caisson " ponding is subsided rest room construction.
Summary of the invention
The object of the present invention is to provide that a kind of antiseep is effective, leak anti-, row of easy construction, washroom that cost is low takes into account construction method.
For achieving the above object, adopt technical scheme as follows:
That caisson type washroom leaks is anti-, row takes into account construction method, comprises the following steps:
1) do hole end leveling layer by cement mortar, leveling layer tilts to pipe root position, corner, and inner corner trim is smeared circular arc;
2) leveling layer brushing polyurethane water-proof paint, along returning 250-350mm height on facade, above wall tile position changes JS cementitious composite water-repellent paint into;
3) after retaining pass the test, convince water hole by patient analysis in ventilating pipe root position, corner, drain retaining, water-guiding hole dresses outside circle stainless (steel) wire or a fleece, then covers polyurethane water-proof layer as protecting insulating layer with cement foam board;
4) sanitaryware are installed, on foam cement plate, are done slag backfill, after tamping, water and smash pea gravel concreten to the following 45-55mm of ground level;
5) after pea gravel concreten dry tack free, brush polyurethane water-proof paint second time, then carry out ground surface construction, after completing, carry out the test of retaining for the second time.
Press such scheme, that described caisson type washroom leaks is anti-, row takes into account construction method, step 2) in when brushing polyurethane water-proof paint, along returning 300mm height on facade.
Press such scheme, that described caisson type washroom leaks is anti-, row takes into account construction method, step 4) water after tamping and smash pea gravel concreten to the following 50mm of ground level.
Beneficial effect of the present invention is mainly:
Toilet warterproof, by designing requirement construction, simultaneously in the perforate of soil stack root, even if ponding is arranged at " caisson " bottom, also can be got rid of from perforate position in time, reaches " anti-, row " double executing, reliable in quality; Replace cement mortar with the waste and old foam cement plate in scene and make polyurethane water-proof topping, both prevented the destruction of cement mortar laying task to waterproofing course, reduce percolating water hidden danger, can be salvaged again, greatly reduce construction cost, and will smear cement mortar protective course operation and change paving foam cement plate operation into, increase material and instrument outward without increment, easy construction, has improved economic benefit;
Detailed description of the invention
Following examples are explaination technical scheme of the present invention further, but not as limiting the scope of the invention.
That caisson type washroom leaks is anti-, row takes into account construction method, and process is as follows:
1) caisson of toilet base cleaning is clean, and the moistening and obvious ponding of sprinkling water does hole end levelling by 1:2 cement mortar, and slightly the gradient is to pipe root position, corner, and inner corner trim is smeared circular arc, and the Polypropylence Sheet shutoff of sanitary equipment drain pipe port, in case foreign material obstruction gutter.A not levelling of fixed gap is reserved in pipe root position, is filled to round pier shape with cement based sealing agent.
2) leveling layer brushing polyurethane water-proof paint, for avoiding capillary attraction water and the aqueous vapor in drying structure, cause water to walk or penetrate wall toward eminence, never doing the position seepage of waterproof goes out, ammonia ester water-repellent paint is along returning 250-350mm height on facade, above wall tile position changes JS cementitious composite water-repellent paint into.In order to avoid affect wall brick adhesive strength.
3) after retaining 24h pass the test, convince water hole by patient analysis in ventilating pipe root position, corner, to drain retaining, for preventing that water-guiding hole from stopping up, water-guiding hole dresses outside circle stainless (steel) wire or a fleece, then covers polyurethane water-proof layer as protecting insulating layer with cement foam board.For preventing that waterproof coating from destroying, utilize on-the-spot old cement foam board to do protecting insulating layer, replace cement mortar protective course, both prevented the destruction of cement mortar laying task to waterproofing course, reduce percolating water hidden danger, can be salvaged again, greatly reduce construction cost, and will smear cement mortar protective course operation and change paving foam cement plate operation into, increase material and instrument outward without increment, easy construction, has improved economic benefit;
4) sanitaryware are installed, on foam cement plate, are done slag backfill, after tamping, water and smash pea gravel concreten to the following 45-55mm of ground level.Foam cement plate between packed layer and polyurethane water-proof layer plays insulation blocking effect, in case backfill sharp object scratches waterproof coating, avoids waterproofing course to lose efficacy.
5) after pea gravel concreten dry tack free, brush polyurethane water-proof paint second time, then carry out ground surface construction, after completing, carry out the test of retaining for the second time.
Repeat such scheme, step 2) in when brushing polyurethane water-proof paint, along returning 300mm height on facade.Repeat such scheme, step 4) water after tamping and smash pea gravel concreten to the following 50mm of ground level.For preventing that toilet water from flowing backwards, toilet design ground is generally lower than other ground, room 50mm left and right.
