7 The other
1. The floor drain and with bent. Standing
No provisions regulating drainage floor drain must set carry water curved, but this is really affect the use of user result. The general water standard atlas of water in the circular is bring, though campanulate water trap.the author plotted to carry water on the part of the highly specific provision, but there is a small, only with water, can make the 30mm stench escaped into the indoor sewers, affect indoor air quality. This is the common problems of plastic drain for many years. Have the floor drain water evaporation or by water easily when decorating, yi was vandalized problem, and because floor drain manufacturing and installation can not meet the design requirements. According to the practical experience, adopt the following methods: all indoor then there are the drainage system of wastewater are supporting installation again floor drain, bending, standing P type water depth to guarantee a 60 ~ 80mm, or should be increased section short tube to increase the water depth, which can effectively prevent the changing phenomenon.
2. Under the catharsis basin sinks and standing bent
On the design drawing elevation said under the condition of the unknown, construction installation personnel often mistaken for lavatory and sinks down in floor standing on bending installation with floor slab is one thing, actually otherwise under. Under the catharsis basin sinks and standing by hair, bend, very easy clastic waits sundry jams, necessitating open mouth of checks on standing QingTong bend. If standing in floor below and bend installation must go to QingTong when the downstairs neighbors house, the average family kitchen, toilet condole top, this will seem very inconvenient. The right way is will s-type standing above the floor bend installation (though not also pick two standing of curved), so in your household QingTong within can always convenient. But standing to remind users bent must not optional cancelled, but after the install instruments must do joint sealing.
3. Big implement of elbow
In the big implement with 90 ° elbow and under the tubes connect is unpleasant, 45 ° elbow hydraulic conditions are not good. The correct installation method is to use a 45 ° elbow and horizontal tubes connection.
4. Traverse pipe and vertical pipe connection problems
In some building drainage, the house traverse pipe and vertical pipe connection adopts a 90 ° elbow, this practice jams rate is higher, the reasonable installation method is to use two 45 ° the elbow with 90 ° connected or inclined tee.
Drain pipe horizontal pipe and horizontal pipe, horizontal pipe and vertical pipe connections, appropriate USES 45 ° tee, 45 ° stone, 90 ° inclined tee, also can use right times or right-angle tee times cross-joint accessories.
5. Pipeline across the floor, walls
Pipeline across the floor, some of construction personnel for the convenience of save trouble, no civil mode branch, just simple occluded by cement mortar after hole, plus hard padded PVC pipe, and concrete appearance smoother adhesive is not very reliable, so very easy to cause serious floor seepage phenomenon, affect resident of normal use. The right way is: add casing in advance, pipe installation shall cooperate to end civil mode branch, and should adopt C20 fine stone concrete points second poured dao and close-grained. After the placement, combining screed-coat or surface should be built around the pipeline, in less than width and thickness of not less than 20mm 30mm deterrence hydrosphere.
Pipeline through a wall and a floor install metal casing (external) or plastic casing, installed in the casing within the top floor should be installed above ground in, decorate 20mm of toilet and kitchen should be within the top casing, and higher ground 50 decorated with floor underside casing bottom should is flat; Installed in the casing wall with its terminals within act of smooth, mutually through floor cracks pipeline between casing and flame retardant close-grained materials and waterproofing applications fill real and end face smooth gel; Through-wall casing and pipeline between aperture fill with flame retardant close-grained materials should be smooth, real and end of the interface may not in pipe tube. 多层住宅建筑给排水英文文献和中文翻译(5):http://www.youerw.com/fanyi/lunwen_6560.html
