Non-descending plate same-floor drainage system and construction method thereof

Abstract

The invention discloses a non-descending plate same-floor drainage system. The same-floor drainage system comprises a plurality of appliance drainage pipes and a same-floor drainage function module, wherein the same-floor drainage function module is fixedly connected with a floor slab, the same-floor drainage function module comprises a module box with an opening in the top side and preset pipe fittings, the preset pipe fittings comprise a multi-channel floor drain, a trap, a three-way pipe fitting and a drainage vertical pipe, the lower part of the three-way pipe fitting, the lower part of the multi-channel floor drain and the trap are all arranged in the module box, a filling material is arranged between the preset pipe fittings arranged in the module box and the inner wall of the modulebox, the multi-channel floor drain comprises a barrel and at least one water inlet branch pipe connected with the side wall of the barrel, the top side and the bottom side of the barrel are open, thebottom side of the barrel is connected with the water inlet end of the trap, the water outlet end of the trap is connected with a transverse pipe of the three-way pipe fitting, the top of the three-way pipe fitting is connected with a drainage vertical pipe, and at least one water inlet branch pipe communicates with one appliance drain pipe. According to the scheme, the non-descending plate same-floor drainage system can be applied to different types of systems, and floor plate descending is not needed in a toilet.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular, the invention relates to a same-floor drainage system without lowering slabs and a construction method thereof. Background technique [0002] In the prior art, most of the drainage toilets on the same floor are sunken toilets (caissons), and there are the following technical problems: [0003] (1) The floor structure is lowered, secondary beams are added, and the floor needs to be backfilled. The construction method is complicated, the indoor net height is greatly affected, and there are many drainage pipe joints. It is troublesome to repair the leakage of pipes during the service period. [0004] (2) Traditional cast-in-place caissons require formwork removal at the construction site, and a large number of steel bar binding work. During the construction process, it is difficult to control the quality of concrete vibration and compactness, and it is difficult to guarantee the ...

AI Technical Summary

Problems solved by technology

[0003] (1) The floor structure is lowered, the secondary beam is added, the floor surface needs to be backfilled, the construction method is complicated, the indoor net height is greatly affected, and there are many drainage pipe joints, and the maintenance of pipe leakage during the service period is troublesome

[0004] (2) Traditional cast-in-place caissons require formwork removal at the construction site, and a large number of steel bar binding work. During the construction process, it is difficult to control the quality of concrete vibration and compactness, and it is difficult to guarantee the construction quality of caisson backfill and waterproof measures.

Long construction period and low construction efficiency

[0005] (3) The production of caisson components in the factory requires customized moulds. The superimposed cast-in-place parts of the caissons need to be ribbed around, and the mold installation is complicated. The caisson components are produced on a fixed table formwork, which needs to be poured in two times. The production period is long and the production efficiency is low. , high cost per component

The cost of logistics and transportation of caisson components is high, the components are heavy and large, and the number of components transported by single vehicle is limited; the hoisting efficiency is low, and the on-site formwork is difficult

On-site installation often occurs steel bar fights, civil engineering construction errors are difficult to control, construction efficiency is low, and the construction period is long

[0006] (4) Leakage, mildew on the wall and floor of the bathroom during use, noise from upstairs drainage, peculiar smell from the dry water seal of the bathroom floor drain, reptiles on the ground, poor drainage or blockage of the floor drain but difficult maintenance

When the toilet is not used satisfactorily, the caisson structure limits the possibility of toilet renovation

[0007] To sum up, the structural design of the drainage toilet on the same floor is complicated, the production and construction are difficult, the efficiency is low, the cost remains high, and quality problems emerge in endlessly

There is an urgent need to develop a drainage system on the same floor without lowering the slab. When the floor structure of the bathroom does not lower the slab, the floor drain will transport the water from the dry and wet area ground to the drainage riser through the same-floor drainage function module, so that the current traditional same-floor The problem of the drainage system is solved; and a construction method of the same-layer drainage system without lowering the board is developed to solve the technical problems of the same-layer drainage system in the prior art such as long construction period and high construction cost
