Description
Technical field
It the utility model is related to toilet warterproof processing technology field, and in particular to caisson of toilet secondary drainage system.
Background technology
Subsided rest room is also known as caisson type toilet, refer to when main body is built by toilet structure sheaf partly or wholly under
Sink from corresponding flooring certain altitude, so that the horizontal drainage pipeline embedment of toilet is wherein, then backfilled with light material.
General toilet design caisson without secondary drainage, when waterproof construction way is improper or the supplying drainage of caisson due to
When aging causes leak, cause the ponding of caisson can not discharge, the long-term ponding of caisson, so as to cause lower floor's ceiling and metope long-term
Counter tide even leaks.
Utility model content
The purpose of this utility model is to provide a kind of caisson of toilet secondary drainage system, to solve because of construction or pipeline
The long-term ponding problem of caisson caused by aging.
To reach above-mentioned purpose, the utility model adopts the following technical solution：
Caisson of toilet secondary drainage system, including caisson and soil stack, soil stack are vertically arranged and run through caisson,
Caisson includes bottom and tank wall, and bottom includes waterproof layer, screed-coat and the Bottom plate of sinkbox set gradually from top to bottom, screed-coat and
Bottom plate of sinkbox fits, and waterproof layer and screed-coat fit；Be equipped with caisson floor drain in caisson, caisson floor drain include water inlet end with
Water outlet, water inlet end are located above waterproof layer, and water outlet is located at below Bottom plate of sinkbox and is connected with soil stack, the caisson
The water inlet end of leakage is covered with into water quantity regulating device；Screed-coat has the gradient, and caisson floor drain is located at screed-coat lower end.
The operation principle of this programme is：
Soil stack is used to discharge the substantial amounts of water produced in life, and bottom and tank wall form the overall structure of caisson, case
Bottom is the three-decker formed by waterproof layer, screed-coat and Bottom plate of sinkbox, and Bottom plate of sinkbox is the lower part of caisson, as stress
Component；Screed-coat is used for the rough surface for filling and leading up Bottom plate of sinkbox, and screed-coat has the gradient, for enabling the ponding in caisson
Smoothly from screed-coat it is high-end to lower end flow；Screed-coat lower end sets caisson floor drain and caisson floor drain connects with soil stack
It is logical, for making the ponding in caisson enter by caisson floor drain in soil stack；Waterproof layer is used to prevent the ponding in caisson from oozing
Penetrate into screed-coat and Bottom plate of sinkbox, the gap in screed-coat and Bottom plate of sinkbox enters in lower floor's ceiling and metope.Caisson
The water inlet quantity regulating device set outside the water inlet end of floor drain is used to adjust the water accumulating volume entered in caisson floor drain, when ponding in caisson
When excessive, water inlet quantity regulating device can increase inflow, the ponding in caisson is faster discharged.
Following technique effect can be reached using this programme：
1st, by setting caisson floor drain in screed-coat lower end so that caisson ponding discharge effect is good, and ponding can be smooth
Soil stack is flowed into from caisson floor drain, avoids long-term ponding in caisson；
2nd, water inlet quantity regulating device can be automatically adjusted into the water accumulating volume in caisson floor drain, avoid ponding mistake in caisson
It is more；
3rd, the setting of waterproof layer can effectively prevent lower floor's ceiling and the long-term counter tide of metope or even leak；
4th, the structure of the system is simple, easy for installation, and installation is time saving and energy saving, and manufacture cost is low.
Further, water inlet quantity regulating device includes adjustment housings, and the first filtration hole and the second filter are offered in adjustment housings
Water hole, the second filtration hole are hinged with baffle close to one end of adjustment housings inner wall, and return unit is equipped between baffle and adjustment housings.
Baffle on second filtration hole is subject to the pressure of caisson ponding and the active force of return unit, when caisson water accumulating volume is smaller, caisson
The pressure of ponding is less than the active force of return unit, and baffle is used to block the second filtration hole, and caisson ponding can only pass through the first drainage
Hole enters in adjustment housings；When caisson water accumulating volume is larger, the pressure of caisson ponding is more than the active force of return unit, and baffle is used for
The second filtration hole is opened, caisson ponding is entered in adjustment housings by the first filtration hole and the second filtration hole at the same time, ponding discharge
Speed is accelerated.
Further, adjustment housings are hemispherical, and the first filtration hole and the second filtration hole are distributed in adjustment housings.Using half
Spherical adjustment housings, can make caisson ponding be smoothly through each first filtration hole and the second filtration hole.
Further, in cone, its miner diameter end is located on the inside of adjustment housings the second filtration hole, and bigger diameter end is located at adjustment housings
Outside.When adopting the structure, baffle is located at the miner diameter end of the second filtration hole, and dam forces area is small, thus baffle is sunk
The pressure of case ponding is big, easily opens baffle.
Further, it is equipped with filter screen in the first filtration hole and the second filtration hole.Filter screen prevent dregs in caisson and
Rubbish enters in adjustment housings, so as to avoid caisson floor drain from blocking, influences caisson floor drain drainage effect.
Further, the outer surface of soil stack is also arranged with one section of casing, and casing is located at soil stack and Bottom plate of sinkbox
At link position.Casing can prevent soil stack to be corroded, and extend the service life of soil stack.
Further, caisson further includes backfill layer, and backfill waterproof layer that backfill layer includes setting gradually from top to bottom, backfill are looked for
Flat bed, precast concrete flaggy and Stilt layer.Backfill waterproof layer is used to prevent that water to enter in caisson in toilet, backfills screed-coat
As the support member of backfill waterproof layer, support member of the precast concrete flaggy as backfill screed-coat, Stilt layer is used for branch
Precast concrete flaggy is supportted, using the backfill layer of such a overhead type, the dead weight of caisson can be reduced.
