Description

A kind of pre-buried double eccentric baffle-type deodorization ponding processors of structural slab of blowdown standpipe

Technical field

A kind of pre-buried double eccentric baffle-type deodorization ponding processors of structural slab of blowdown standpipe of the utility model, belong to packing course Internal water accumulation draining deodorization apparatus technical field.

Background technology

The drainage system of modern architecture industry, the drainage system especially in toilet, Homofloor drainage system, geothermal system, Structural slab is to finished surface at least 100mm~200mm packing course；Water appliance is such as washbowl, shower, bathtub, washing machine etc. Drainpipe is all to be arranged on through finished surface in packing course, so as time went on, is artificially trampled, the original such as waterproof material aging Cause, the drainpipe for installing water appliance passes through the place of finished surface, such as floor tile junction, all toward seeping water in packing course, for this Problem, people are typically solved using following methods：

First, it is arranged on soil stack and is drained the water away with non-water sealed ponding processor.Set osculum several, still Because ponding is not perennial draingage, and water accumulating volume is few, it is only necessary to which just, other just into back foul hole, wait to accumulate one or two of osculum Water has excluded, and all holes are just all into back foul hole, and because ponding processor is arranged on soil stack, osculum connects with septic tank Connect, thus form a passage, the substantial amounts of foul smell as chimney, a large amount of pernicious gases return to interior, greatly influence to occupy Firmly environment, there is epidemic situation then more fearful.As the Amoy Garden of Hong Kong in 2003, because drainage pipeline trap improper use, Water can not be supplemented in time, causes trap anhydrous, do not have water seal effect, someone uses toilet with SARS virus, non- Allusion quotation virus is discharged in septic tank, is made to live in the people of Amoy Garden 321 and is all infectd SARS virus, the national whole world of stretching, this It is example, it is acknowledged, it is distressed historical lessons, the processing of this non-water sealed ponding can absolutely not use, and definitely be to victimize, It is installed to be equal to install a time bomb.

Second, after the completion of waterproof layer, water storage examination is done, 24 hours are non-leakage to be qualified.At this moment water storage is manually excluded, both Take a lot of work and not thoroughly, so worker excludes in soil stack punching violating the regulations, it is believed that there is ponding to flow out in future packing course, Such way temporarily excludes water storage in fact, but leaves great trouble, because soil stack is through perennial draingage, and close to tube wall stream Water, through sewage is flowed back into packing course from the hole that standpipe is beaten, this is also one of the reason for causing ponding, can also be returned a large amount of smelly Gas, a large amount of pernicious gases are discharged to interior.

3rd, also it is a kind of be not pre-buried structure plate ponding processor, it is necessary to secondary frame template is taken a lot of work, and more important pole holds Easily toward lower floor leak, ability pipe laying and ponding processor after structural slab is completed 1 year, structural slab through being bone dry so long, It will not shrink, only encapsulant shrinks, and preformed hole fixes a drainpipe and ponding processor, surrounding must do encapsulation process, Encapsulant can not form one with structural slab, and when encapsulant is done, structural slab does not shrink, what encapsulant shrank certainly, That forms dry and cracked seam, destroys waterproof layer, has water just toward one layer of leak downstairs, cause up and down resident be discord, produce contradiction.

In a word, above-mentioned solution method can absolutely not be taken.

Relevant criterion has just been promulgated early in country in 2003, and come into effect from September in 2003 1 day in fact, GB50015-2003 " Code for design of building water supply and sewerage " 4.2.6 of page 59, when the sanitary apparatus in structure without trap and life When sewage conduct living or other drainage pipelines that can produce pernicious gas connect, it is necessary to divide into trap, trap in discharge outlet Water seal depth cannot be less than 50mm.Forbid to replace water seal using mobile machine sealing.
