Abstract
The utility model discloses a concrete inspection shaft which comprises shaft upper portion, a shaft middle portion and a shaft lower portion poured by concrete. The shaft upper portion is of a conical hollow structure. The shaft middle portion and the shaft lower portion are of cylindrical structures. At least one circular hole is reserved on the lateral edge of the shaft lower portion. The inner and outer diameters of a lower opening of the shaft upper portion are consistent with the inner and outer diameters of the shaft middle portion and the shaft lower portion. By the structure, the shaft upper portion, the shaft middle portion and the shaft lower portion are poured on the ground and assembled underground, and accordingly the concrete inspection shaft is convenient to manufacture and mount, firm in structure, long in service life, and good in application effect.
Description
Technical field
The utility model relates to the drainage such as rainwater, sewage field, is specifically related to a kind of concrete inspection well.
Background technology
Rainwater, sewage inspection well are a kind of urban road communal facilitys, generally be located on drainage pipe intersection, turning, caliber or gradient change place, drop place and diameter pipeline section and locate at a certain distance, be convenient to make regular check on, the draining ancillary building of cleaning and dredging pipeline.Existing rainwater, sewage inspection well generally are divided into the mixed manhole of brick and plastic inspection well, the mixed manhole of brick because manhole by fragment of brick or stone and concrete integral shaping, will be at underground job during making, environment is abominable, work inconvenience; And there is insufficient strength in plastic inspection well, easily damages, thereby occurs leaking or caving in, and the problem because rainwater, sewage inspection well distortion cause well lid to come off can cause vehicle damage like this, can cause traffic accident when serious.Simultaneously, well lid comes off and also can make ground earth, foreign material fall into obstruction in well, makes drainage pipe be difficult to normal draining.
The utility model content
For solving the problems of the technologies described above, we have proposed a kind of concrete inspection well, make and easy for installation, sound construction, long service life and the good purpose of effect to reach.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of concrete inspection well is comprised of the aboveground section of concreting, well middle part and down-hole section; Described aboveground described well middle part and down-hole section are tubular construction for the taper hollow-core construction, and described down-hole section side has at least one circular opening; Described aboveground subordinate's mouth internal-and external diameter and described well middle part and down-hole section internal-and external diameter are consistent.
Preferably, described aboveground inward flange suitable for reading is provided with the annular protrusion for the carrying well lid.
Preferably, described down-hole subordinate's mouth outward flange is provided with annular boss.
By technique scheme, the utility model is comprised of the aboveground section of concreting, well middle part and down-hole section by manhole is designed to; Described aboveground described well middle part and down-hole section are tubular construction for the taper hollow-core construction, and described down-hole section side has at least one circular opening; Described aboveground subordinate's mouth internal-and external diameter and described well middle part and down-hole section internal-and external diameter are consistent; Aboveground section, well middle part and down-hole section are built on the ground, then assemble underground, make and easy for installation, sound construction, long service life and the good purpose of effect to reach.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of concrete inspection well, makes and easy for installation, sound construction, long service life and the good purpose of effect to reach.
Below in conjunction with embodiment and the specific embodiment, the utility model is described in further detail.
Embodiment.
As depicted in figs. 1 and 2, a kind of concrete inspection well is comprised of aboveground 1 of concreting, well middle part 2 and down-hole section 3; Described aboveground 1 described well middle part 2 and down-hole section 3 are tubular construction for the taper hollow-core construction, and described down-hole section 3 sides have two circular openings 4; Described aboveground 1 end opening internal-and external diameter is consistent with described well middle part 2 and down-hole section 3 internal-and external diameters.
Wherein, described aboveground 1 inward flange suitable for reading is provided with the annular protrusion 11 for the carrying well lid; In order to increase the contact area in down-hole section 3 and shaft bottom, it is stablized more firm, described down-hole section 3 end opening outward flanges are provided with annular boss 31.
in this example, when in drainage pipe intersection, the turning, caliber or gradient change place, when need locating at a certain distance the installing manhole on drop place and diameter pipeline section, at first as required specification, make mould and just build on the ground aboveground 1 of manhole carefully, well middle part 2 and down-hole section 3, then it is pressed down-hole section 3, well middle part 2 and aboveground 's 1 order is packed into underground successively, then with the joint encapsulation process, last at annular protrusion 11 places of well lid being covered at aboveground 1, again it is hung out underground getting final product when needing repairing or change, it all need not be hung out or changes the inconvenience that brings because of heaviness.
By technique scheme, the utility model is comprised of aboveground 1 of concreting, well middle part 2 and down-hole section 3 by manhole is designed to; Described aboveground 1 described well middle part 2 and down-hole section 3 are tubular construction for the taper hollow-core construction, and described down-hole section 3 sides have two circular openings 4; Described aboveground 1 end opening internal-and external diameter is consistent with described well middle part 2 and down-hole section 3 internal-and external diameters; Aboveground 1, well middle part 2 and down-hole section 3 are built on the ground, then assemble underground, make and easy for installation, sound construction, long service life and the good purpose of effect to reach.
Above-described is only a kind of concrete inspection well preferred embodiment of the present utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
