The first connection pipe 101, the second connection pipe 201, the third connection pipe 301, and the manifold 501 are disposed in the blanket 701. Although the problem that the first generation interlayer drainage seepage influences the lower floor resident is solved, when the second generation drainage system is used, the height of the floor slab needs to be reduced at the pipeline installation position, in the prior art, the height of the floor slab is approximately reduced by 40CM, the floor slab occupies the space of the lower floor resident in a large amount, the water accumulation phenomenon is easy to occur in the cushion layer, and the pipeline is difficult to overhaul and inconvenient to construct.

Example 1

Referring to fig. 3 to 10, the embodiment provides a building micro-drop plate same-floor drainage assembly, which is internally connected between main drainage pipelines and is vertically communicated with the main drainage pipelines when being actually installed. The device comprises a horizontal pipe drainage component 2 communicated with a main drainage pipeline and a water seal component 3 communicated with the horizontal pipe drainage component 2. In the present embodiment, the waste water refers to water discharged from a shower, a wash basin, a balcony, a washing machine, and the like.

Referring to fig. 4 to 9, the horizontal pipe drainage assembly 2 in this embodiment is a flat hollow cavity inside, and is used for collecting the wastewater drained by the water seal assembly 3 into the main drainage pipeline, one end of the horizontal pipe drainage assembly 2 is communicated with the main drainage pipeline, and the other end is communicated with the water seal assembly 3; the bottom surface of the cavity of the horizontal pipe drainage component 2 is obliquely arranged, and one end connected with the water seal component 3 is higher than the other end of the horizontal pipe drainage component 2. The inclined arrangement of the bottom surface of the horizontal pipe drainage assembly 2 is used for reducing the waste water temporarily remained in the horizontal pipe drainage assembly 2, so that the waste water introduced by the water seal assembly 3 flows under the action of self gravity and can be smoothly collected into a main drainage pipeline. Moreover, when the discharge amount of wastewater in the main drainage pipeline is large and the water pressure is greater than the water pressure of wastewater drained by the water seal assembly 3, the wastewater can also flow back to the main drainage pipeline to be discharged due to the influence of gravity, so that the wastewater is prevented from being reversely discharged to the water seal assembly 3.

Further, the horizontal pipe drainage assembly 2 comprises a first fitting part 21 and a second fitting part 22, and the first fitting part 21 and the second fitting part 22 are closed to form a cavity of the horizontal pipe drainage assembly 2 for circulating waste water; the bottom surface of the cavity of the horizontal pipe drainage assembly 2 is inclined, in particular to the bottom surface of the second assembly part 22.

In the embodiment, the first assembly member 21 and the second assembly member 22 are made of plastic, so as to reduce the weight of the first assembly member 21 and the second assembly member 22, and prevent the first assembly member 21 and the second assembly member 22 from rusting and damaging the service life thereof; and the first assembly part 21 and the second assembly part 22 made of plastics have low production and processing cost and are convenient to assemble. Indeed, in other preferred embodiments, the first assembly member 21 and the second assembly member 22 may be made of cast iron or ceramic.

Further, the first assembly part 21 and the second assembly part 22 are of an integrated structure, so that the possibility of leakage of waste water from the horizontal pipe drainage component 2 is reduced, and the sealing performance of the horizontal pipe drainage component 2 is improved.

Further, the first fitting 21 comprises a first riser interface 211 and a waste pipe interface 212; the second fitting 22 comprises a second riser interface 221 and a trap interface 222; the upper main drainage pipeline is communicated with the horizontal pipe drainage component 2 through a first vertical pipe connector 211, and the lower main drainage pipeline is communicated with the horizontal pipe drainage component 2 through a second vertical pipe connector 221.

Further, the second assembly 22 further includes a second vertical pipe 27 inserted into the lower main drainage pipeline, the second vertical pipe 27 is communicated with the second vertical pipe connector 221, and a convex ring 271 for abutting against the port of the lower main drainage pipeline is disposed on the outer wall of the second vertical pipe 27. Specifically, the upper end of the second riser 27 is communicated with the second riser joint 221, and the lower end of the second riser 27 is communicated with the lower main drainage pipeline. In this embodiment, the second vertical pipe 27 and the main drainage pipeline are connected in an inserting manner and fixed by glue, and in order to prevent the waste water from overflowing from the joint of the second vertical pipe 27 and the main drainage pipeline, the part of the second vertical pipe 27 inserted into the main drainage pipeline needs to have a sufficient insertion length; the convex ring 271 is a complete circular ring-shaped integrated formed on the outer wall of the second vertical pipe 27, the convex ring 271 can be used for realizing the plugging and positioning of the second vertical pipe 27 and the main drainage pipeline, and the convex ring 271 can also strengthen the sealing performance of the joint of the second vertical pipe 27 and the main drainage pipeline.

Further, the second assembly member 22 and the second vertical pipe 27 are of an integrated structure, so that the influence of resistance on the fluidity of the waste water at the joint due to a non-integrated structure is reduced, the waste water can be discharged in a swirling manner along the wall of the pipe, and the possibility of leakage is reduced.

Further, the bottom surface of the second fitting 22 in this embodiment is obliquely disposed at an angle such that water entering the horizontal pipe drain assembly 2 can enter the second riser pipe 27 in a tangential direction of the second riser pipe 27, thereby reducing the possibility of a water plug forming in the second riser pipe 27.

Further, in the use process of the building micro-landing slab same-layer drainage assembly, wastewater may be deposited on the floor surface, in order to drain the wastewater deposited on the floor surface into the second vertical pipe 27, the horizontal pipe drainage assembly 2 further comprises an anti-overflow mechanism which is arranged in the cavity and is positioned at the second vertical pipe interface 221, and the anti-overflow mechanism comprises an anti-overflow ball seat 23 and an anti-overflow ball 24; the overflow-preventing ball seat 23 is provided with a water accumulation discharge hole 231 communicated with the second riser 27, and the overflow-preventing ball 24 is placed on the water accumulation discharge hole 231; a accumulated water inflow hole 232 is further formed in the first assembly member 21 at a position corresponding to the accumulated water discharge hole 231, and the diameter of the accumulated water inflow hole 232 is smaller than that of the anti-overflow ball 24.

Specifically, the anti-spill ball seat 23 is arranged on the inner wall of the second assembly member 22; the centers of the water inflow hole 232 and the water discharge hole 231 are located on the same axis.

Therefore, the accumulated water discharge hole 231 formed in the anti-backflow ball seat 23 horizontally limits the anti-backflow ball 24, and the anti-backflow ball 24 can only vertically move between the anti-backflow ball seat 23 and the accumulated water discharge hole 231 formed in the anti-backflow ball seat 23. When water accumulation exists on the floor surface, accumulated water can enter through the accumulated water inflow hole 232 and flow out of the accumulated water outflow hole 231, and then is discharged into the second riser 27; meanwhile, when the overflow of the wastewater occurs, the overflow preventing ball 24 is tightly attached to the accumulated water inflow hole 232 by the buoyancy of the wastewater to seal the accumulated water inflow hole 232, so as to prevent the overflowing wastewater in the second riser 27 from overflowing the cyclone.

Further, the horizontal tube drain assembly 2 further comprises a drainage plate 26. The flow guide plate 26 is arranged at the second vertical pipe interface 221 and is used for guiding the wastewater flowing into the horizontal pipe drainage assembly 2 from the water seal assembly 3 to enter the second vertical pipe 27 along the tangent line of the second vertical pipe 27 so as to realize wall-attached rotational flow of the wastewater; or when the flow of the wastewater in the horizontal pipe drainage assembly 2 is large, in order to ensure that the wastewater can enter the second vertical pipe 27 along the tangential direction of the second vertical pipe 27, the wastewater entering the horizontal pipe drainage assembly 2 enters the second vertical pipe 27 along the tangential direction of the second vertical pipe 27 under the guidance of the drainage plate 26, and when the flow of the wastewater in the horizontal pipe drainage assembly 2 is large, the wastewater can still be discharged in a wall-attached swirling manner from the second vertical pipe 27.

Example 3

Referring to fig. 14 and 15, the present embodiment is technically different from embodiment 1 only in that the building descender floor drainage assembly further comprises a drainage pipe assembly 1 communicated with the horizontal pipe drainage assembly 2.

In this embodiment, the lower end of the drain pipe assembly 1 is communicated with the upper end of the horizontal pipe drain assembly 2, the upper end of the drain pipe assembly 1 is communicated with the upper main drain pipe, and the lower end of the horizontal pipe drain assembly 2 is communicated with the lower main drain pipe. In the present embodiment, the sewage refers to water discharged from the horse tub. Therefore, toilet sewage is guided to the horizontal pipe drainage assembly 2 through the drainage pipe assembly 1 and is discharged into the main drainage pipeline, and the discharge of the sewage is realized.

Referring to fig. 14 and 15, the drain pipe assembly 1 includes a first inlet pipe 11, a second inlet pipe 12, and a first riser pipe 13; the first water inlet pipe 11 is connected with the second water inlet pipe 12 and communicated with the inside of the first water inlet pipe, and the inner edge of the second water inlet pipe 12 is tangent to the inner edge of the first water inlet pipe 11, so that sewage can flow into the first water inlet pipe 11 along the inner wall of the second water inlet pipe 12; the first water inlet pipe 11 is connected with the first vertical pipe 13 and is internally communicated, the second water inlet pipe 12 can be communicated with a toilet sewage discharge port for receiving sewage of the toilet sewage discharge port, and the sewage enters the first water inlet pipe 11 along the second water inlet pipe 12. Wherein, the first stand pipe 13 of the drainage pipe assembly 1 is communicated with the horizontal pipe drainage assembly 2 through a first stand pipe interface 211.

In this embodiment, the first water inlet pipe 11 and the second water inlet pipe 12 are an integrally formed structure, and the first water inlet pipe 11 and the first vertical pipe are sleeved and adhered together. In addition, an included angle of 80-100 degrees is formed between the second water inlet pipe 12 and the first water inlet pipe 11, the first vertical pipe 13 is communicated with the horizontal pipe drainage component 2, and all sewage collected by the collecting system of the embodiment is discharged into a total sewage discharge pipeline through the horizontal pipe drainage component 2.

Further, the pipe wall cavity 15 that the second inlet tube 12 and the first inlet tube 11 intercommunication department are the volume inflation, when sewage along second inlet tube 12 entering first inlet tube 11, the curvature radius that sewage pasted the pipe wall whirl can be increased in setting up of pipe wall cavity 15, when sewage discharge capacity is big, effectively reduce sewage discharge rate, ensure that sewage can hug closely the pipe wall whirl, avoid because of pipeline curvature radius undersize, sewage when sewage discharge capacity is big direct current discharges from the pipeline and causes the time of the drainage big noise, reduce pipeline life scheduling problem.

Further, the shape of the first water inlet pipe 11 is a funnel-shaped structure with an expanded upper end opening and a reduced lower end opening from top to bottom, the inner diameter of the upper end opening of the first water inlet pipe 11 is larger than the inner diameter of the first vertical pipe 13, and the inner diameter of the lower end opening is close to the inner diameter of the first vertical pipe 13 and can be sleeved with the first vertical pipe 13. The inner diameter of the upper end opening of the first water inlet pipe 11 is larger than the inner diameter of the first vertical pipe 13, so that the curvature radius of the sewage is increased when the sewage clings to the wall of the pipe, the rotational flow radius is gradually reduced when the sewage clings to the wall of the pipe, and finally the sewage enters the first vertical pipe 13 and the horizontal pipe drainage assembly 2 to be discharged into a main sewage discharge pipeline.

Further, a pipe cover 111 is further arranged at an opening at the upper end of the first water inlet pipe 11, a pipe joint 112 is arranged on the pipe cover 111, and the pipe joint 112 is communicated with the first water inlet pipe 11 and is used for being connected with a main drainage pipeline.

Therefore, the concrete implementation manner of the building descent plate same-layer drainage assembly internally connected to the sewage main drainage pipeline in the embodiment is that the pipe connector 112 of the drainage pipe assembly 1 is communicated with the upper-layer main drainage pipeline at the upper end of the collection system, the second vertical pipe 27 is communicated with the lower-layer main drainage pipeline at the lower end of the collection system, and thus the drainage collection system is communicated with the main drainage pipeline up and down. In this embodiment, the upper-layer main drainage pipeline refers to the part of the main drainage pipeline positioned on the upper side of the drainage pipe assembly 1 with reference to the three-dimensional space of the building, and the lower-layer main drainage pipeline refers to the part of the main drainage pipeline positioned on the lower side of the horizontal drainage assembly 2.

Further, in practical use, the temperature of the sewage discharged into the first vertical pipe 13 varies according to the source, and the temperature of the sewage varies, for example, the temperature of the waste water generated by showering is higher than the temperature of normal domestic water by approximately 30 ℃, and the temperature difference of the sewage causes thermal expansion and cold contraction of the first vertical pipe 13, so that the first vertical pipe 13 extends or contracts, thereby affecting the sealing property of the connection between the upper-layer main drainage pipeline and the pipe joint 112, and therefore, in order to reduce the influence of the thermal expansion and cold contraction on the overall sealing property of the drainage pipe assembly 1 and compensate the deformation of the first vertical pipe 13 when the temperature of the sewage varies, the drainage pipe assembly 1 further comprises an expansion joint 16, and the expansion joint 16 is inserted into the pipe joint 112; the telescopic joint 16 comprises an outer circular pipe 161 and an inner circular pipe 162 which are sleeved with each other, the outer circular pipe 161 is communicated with an upper layer main drainage pipeline, the outer circular pipe 161 and an upper layer sewage drainage pipe can slide relatively, and the telescopic range of the telescopic joint 16 can reach 102mm at most. In order to improve the sealing performance of the connection between the telescopic joint 16 and the upper-layer main drainage pipeline, a sealing ring 163 is arranged on the inner wall of the upper end of the telescopic joint 16.

Further, in order to avoid the upper drainage pipe sewage from whirling and entering the first water inlet pipe 11, or when sewage from the second water inlet pipe 12 whirling and entering the first water inlet pipe 11, the sewage can rush out of the second water inlet pipe 12 along the junction of the first water inlet pipe 11 and the second water inlet pipe 12, resulting in sewage convection, the drainage pipe assembly 1 in this embodiment further includes a baffle 113, the baffle 113 is disposed between the inner connection of the first water inlet pipe 11 and the second water inlet pipe 12. After the baffle 113 is arranged at the joint of the second water inlet pipe 12 and the first water inlet pipe 11, sewage in the second water inlet pipe 12 can enter the first vertical pipe 13 according to a set direction, the sewage in the first water inlet pipe 11 is prevented from reversely entering the second water inlet pipe 12, and the cyclone direction of the sewage entering the first vertical pipe 13 is the same as the cyclone direction of the sewage in the first vertical pipe 13.

Further, when the drainage pressure (the drainage pressure is, when sewage flows along the wall) of the upper-layer main drainage channel into the first water inlet pipe 11 is greater than the drainage pressure of the second water inlet pipe 12 into the first water inlet pipe, the water flow of the first water inlet pipe 11 may flow reversely into the second water inlet pipe 12. In order to avoid the above situation, the water discharging pipe assembly 1 in this embodiment further includes a pressure stabilizing film 114 disposed at the connection portion of the second water inlet pipe 12 and the first water inlet pipe 11, where the material of the pressure stabilizing film 114 is not particularly limited, and the pressure stabilizing film 114 in this embodiment is made of a flexible material. When the sewage in the second water inlet pipe 12 enters the first water inlet pipe 11, the pressure stabilizing film 114 does not influence the sewage to enter the first water inlet pipe 11 along the pipe wall cavity 15. When the drainage pressure of the first water inlet pipe 11 is greater than that of the second water inlet pipe, sewage in the first water inlet pipe 11 impacts the pressure stabilizing membrane 114, and the pressure stabilizing membrane 114 prevents the sewage in the first water inlet pipe 11 from entering the second water inlet pipe 12 due to pressure difference, so that the sewage can be stably discharged from the first vertical pipe 13 in a wall-attached rotational flow manner; when the drainage pressure in the first water inlet pipe 11 is equal to the drainage pressure of the second water inlet pipe, the pressure stabilizing membrane 114 is in a normal assembly state, and the drainage of pipeline sewage is not influenced; when the drainage pressure in the first water inlet pipe 11 is less than the drainage pressure of the second water inlet pipe, the pressure stabilizing film 114 is impacted by the sewage discharged by the second water inlet pipe 12 and is sunken inwards along the radial direction of the first water inlet pipe 11, so that the discharge space of the second water inlet pipe 12 is enlarged, and the final wall-adhering rotational flow of the sewage is ensured to be stably discharged from the first vertical pipe 13. In addition, when the discharge amount of sewage in the first water inlet pipe 11 attached to the inner wall of the first water inlet pipe 11 and the spiral flow velocity are large, the air flow is disturbed to form negative pressure suction force, and meanwhile, the drainage pressure of the pipe wall of the sewage formed by the large drainage amount to the sewage is large, when the pressure stabilizing film 114 is not arranged, because the negative pressure suction force and the drainage pressure are dispersed on the contact surface of the negative pressure airflow, the pipe wall and the sewage and cannot be mutually offset, the toilet water seal is easily caused to lose efficacy by the negative pressure suction, the arrangement of the pressure stabilizing film 114 enables the negative pressure suction force and the drainage pressure to jointly act on the pressure stabilizing film 114, and the three rigidity forces of the pressure stabilizing film 114 are mutually offset, so that the effect of reducing the air pressure fluctuation of the second water inlet pipe 12 is achieved, the system damping is increased, and the risk of the toilet water seal losing. When being the malleation in the first inlet tube 11, steady voltage membrane 114 expands along first inlet tube 11 radial outside to reach and alleviate the undulant mesh of pressure in the second inlet tube 12, increase system damping, reduce the closestool water seal and lead to the risk of losing efficacy because of the malleation splash.

Further, the first vertical pipe 13 in this embodiment adopts a single vertical pipe, and can realize the functions of water drainage and air exhaust at the same time, thereby significantly saving the building space.

The drain pipe assembly 1 of this embodiment is when drainage and exhaust, in order to avoid the water stopper (dirty waste water is for pasting the pipe wall whirl discharge under normal conditions, when the whirl is discharged, can form a hollow air column and supply waste gas to discharge, but if sewage not hug closely the lateral wall whirl of first riser 13 and discharge, and directly discharge from the hollow part of first riser 13, sewage occupies the passageway that gas discharged from first riser 13, when leading to waste gas can't discharge, then the phenomenon of blockking up first riser 13), the setting of pipe wall cavity 15 for sewage in the first riser 13 also can discharge in the mode of adherence whirl when the flow is big, avoid the water stopper to form, increase the displacement, reduce the production of drainage noise simultaneously.

In summary, the building micro-drop plate same-layer drainage assembly provided by the invention adopts the flat horizontal pipe drainage assembly 2 to connect the water seal assembly 3 to the main drainage pipeline, so that the occupied space is small, and the drainage of wastewater can be realized only by reducing the height of a smaller floor; the bottom of the horizontal pipe drainage component 2 is obliquely arranged skillfully by utilizing the gravity principle, wastewater is collected to a main drainage pipeline, the structure is simple, the production cost is greatly reduced, and the horizontal pipe drainage component is skillfully matched with the water storage part 31 of the water seal component 3, so that the wastewater flowing out of the water storage part 31 to the horizontal pipe drainage component 2 can overflow to the periphery of the opening end 311 of the water storage part 31, the drainage space of the wastewater is enlarged, and the wastewater can not be drained in time; the floor drain cover 321 of the floor drain 32 of the water seal assembly 3 is connected with the detachable connection structure of the support member 322, the first filter screen 3223 is connected with the mounting groove 3222 of the support member 322 in a clamped mode, the connection pipe 34 is connected with the detachable connection structure of the waste water pipe 33, when the interior of the collecting system is blocked, a maintenance worker can maintain the blocked part without removing a wall, the blockage fault can be maintained only by removing the floor drain cover 321 at the floor drain 32, the first filter screen 3223, the second filter screen 341 and the connection pipe 34, the operation is convenient and easy, particularly, the flow guide pipe 35 is arranged on the side wall of the waste water pipe 33, and when the flow guide pipe 35 is blocked, the maintenance worker can maintain only by removing the parts.
