Abstract
The invention belongs to the technical field of building water supply and drainage systems, and particularly relates to a rain and sewage backflow prevention inspection well facility. The invention is mainly characterized in that rainwater and sewage drainage in industrial and civil building parks are conducted in a single direction and cut off in a reverse direction, namely, the unidirectional drainage of industrial and civil building parks such as houses, businesses, offices, commercial complex states, factory buildings and the like is realized under the gravity flow or natural state of rainwater and sewage in the parks to prevent municipal rainwater and sewage from flowing backwards to the parks. The invention fundamentally solves the problem that municipal rainwater and sewage flow back to the garden to cause serious water accumulation or waterlogging in industrial and civil building gardens of residences, businesses, offices, commercial complexes, plants and the like in the urban construction process due to too shallow municipal rainwater and sewage pipeline burying or too large municipal rainwater and sewage amount.
Description
Technical Field
The invention relates to the technical field of building water supply and drainage systems, in particular to a rain and sewage backflow prevention inspection well facility.
Background
Along with the development of social economy, the industrial and civil building industry has also gained vigorous development, from this, the smooth discharge of inside rainwater, the sewage of industrial and civil building garden has played crucial effect to garden quality and comfort level, because in recent years the climate uncertainty and municipal pipe network supporting construction's hysteresis quality and backward nature, the stability of building garden drainage and reliability require more and more high.
Disclosure of Invention
The invention aims to overcome the problems in the prior art, provides a facility based on a backflow-preventing inspection well, and can fundamentally solve the problem that municipal rain and sewage flow back to a park to cause serious water accumulation or waterlogging in industrial and civil building parks such as houses, businesses, offices, commercial complexes, factory buildings and the like in the urban construction process due to shallow burying of a municipal rain and sewage pipe network or overlarge quantity of municipal rain and sewage.

FIG. 4 is a schematic view of an N-N section (sewage) of an inspection well for preventing rain and sewage from flowing backward in example 1 of the present invention;
Detailed Description
In order to make the technical means, the creation characteristics, the achievement objects and the functions of the present invention easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
The rain and sewage backflow prevention inspection well comprises a cast-in-place reinforced concrete rainwater and sewage inspection well 1, a reinforced concrete cover plate 2, a C30 concrete well ring 3, a phi 700 or phi 800 cast iron well cover and support 4, a phi 700 or phi 800 precast concrete well barrel 5, a launder 6, a step 7, a C10 concrete cushion layer 8, basement old soil 9, a flap valve 10, a rubber sealing ring 11, an expansion bolt 12 and a pipe 13, wherein the cast-in-place reinforced concrete rainwater and sewage inspection well 1 is arranged in the well cover; technical personnel can determine to adopt a structural form of the rainwater or sewage backflow prevention inspection well 1 according to actual needs, and the difference of the rainwater or sewage backflow prevention inspection well 1 lies in a form of a chute 6 at the bottom of the inspection well, when pipelines with the same height of the chute 6 of the rainwater inspection well are connected, the top of the chute 6 is level with the center of a pipe, when pipelines with different diameters are connected, the top of the chute is generally level with the center of a small pipe, and the height of the chute of the sewage inspection well is that the top of the chute is generally level with the top of the pipe; when the form of the rainwater or sewage backflow prevention inspection well 1 is selected, the specification and the model of the flap valve 10 are selected according to the specification and the model of the pipe 13, the model of the flap valve 10 can be a free circular cast iron flap valve or a free lateral single-opening circular flap valve, and when the diameter of the flap valve is smaller than 1000mm, the free lateral single-opening circular flap valve is suggested. After determining the specification and model of the pipe 13 and the flap valve 10, a technician performs construction and installation according to the figures 1-4 in the attached drawings of the specification.
The preferred embodiments of the invention disclosed above are intended to be illustrative only. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and the practical application, to thereby enable others skilled in the art to best utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
