Description
Technical Field
The utility model belongs to the technical field of urban drainage pipe, especially, relate to an inspection shaft well room.
Background
The inspection well is used as a mixed junction for connecting the existing urban drainage pipeline network, is installed in a drainage pipeline network in a matching way with a main pipeline, and realizes the periodic inspection, cleaning and dredging functions of the pipeline network.
In the process of implementing the present invention, the inventor finds that the prior art has at least the following problems: the inspection well chamber in the prior art usually adopts cement concrete module inspection well chamber, brick inspection well chamber and plastics inspection well chamber, and the prior art has following shortcoming:
1. the concrete module inspection well chamber and the brick inspection well chamber are rigidly connected with the pipeline, so that the foundation settlement resistance is poor, the joint is easy to leak, and the corrosion resistance of the well chamber body is poor; the construction period is long, the engineering cost is high, the service life is short, and the materials cannot be recycled and wasted;
2. the plastic inspection well chamber body has low strength, and is easy to break under stress to cause secondary pollution to water; the method is limited in use environment, and is generally suitable for a shallow buried environment with small road surface load; the application specification is limited, and DN of a general pipeline is less than or equal to 400; the secondary recovery is not timely, the utilization is unreasonable, and the environment and the human life are seriously affected.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a transfer in the production degree of difficulty, the convenient transportation and the project installation of reduction well room is provided, the assembly is simple convenient, the inspection shaft well room that assembly structure stability is good.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: an inspection well chamber having:
a shaft buried under a road surface;
the upper end of the well chamber body is connected with the lower end of the shaft; the well chamber body comprises an upper well chamber and a lower well chamber, and the upper well chamber is clamped with the lower well chamber;
the cushion layer is arranged on the lower layer of the pavement and is matched with the shaft through a retaining ring;
and the support ring is arranged between the road surface and the cushion layer.
And the clamping ends of the upper well chamber and the lower well chamber are provided with sealing rings.
Still have inspection well lid, inspection well lid with the upper end of pit shaft is connected and seals the upper end of pit shaft.
The shaft is a ductile iron pipe; the well chamber body is made of nodular cast iron.
One of the technical scheme has following advantage or beneficial effect, has solved because of the too big production, transportation, the project installation difficult problem that leads to the high too high production that brings of inspection shaft well room of trunk line bore, reduces the production degree of difficulty of well room, the allocation and transportation in convenient transportation and the project installation, and the assembly is simple convenient, and assembly structure stability is good.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1-2, an inspection well chamber having:
a shaft buried under a road surface;
the upper end of the well chamber body is connected with the lower end of the shaft; the well chamber body comprises an upper well chamber and a lower well chamber which are clamped; the inspection well chamber is divided into an upper part and a lower part, the upper part and the lower part of the inspection well chamber adopt a socket type assembly structure, and meanwhile, a rubber sealing ring is arranged at the matching part of the bell mouth and the spigot to prevent the ground or underground water from leaking into the inspection well chamber. The upper well chamber and the lower well chamber are assembled after being produced and manufactured in a split mode by adopting a lost foam process. The split assembly type inspection well chamber effectively reduces the overall height for manufacturing the inspection well chamber of the large-caliber main pipeline, greatly reduces the production, transportation and on-site installation and transportation difficulty, and improves the production efficiency and the engineering efficiency.
The cushion layer is arranged on the lower layer of the pavement and is matched with the shaft through a retaining ring; and the support ring is arranged between the road surface and the cushion layer. And the clamping ends of the upper well chamber and the lower well chamber are provided with sealing rings. Still have inspection shaft lid, inspection shaft lid is connected and seals the upper end of pit shaft with the upper end of pit shaft. The shaft is a nodular iron pipe; the well chamber body is made of nodular cast iron.
In the process of integrally assembling the nodular cast iron split assembly type inspection well chamber, the shaft and the inspection well cover, the inspection well chamber is connected with the main pipeline in a socket joint mode; the shaft is made by cutting a nodular iron pipe on site and assembling the shaft and a well chamber by adopting a socket installation structure, so that the stability of the assembly structure is good;
soil around the well body is backfilled evenly and smoothly, a certain height is reserved from the upper end face of the well shaft, observation is paid attention in the soil backfilling process, and the condition that the well shaft is stressed unevenly and inclined is avoided. Then the manhole cover is installed.
Buried pipe network construction, inspection well lid need adopt and prevent subsiding the well lid, and sufficient safe distance is reserved to well lid and pit shaft up end, and the well lid is done sealing device and bed course all around, and the effect of adopting to prevent subsiding the well lid is in order to avoid inspection well lid to receive ground load effect, leads to inspection well lid ring around splitting and the well lid danger of collapsing.
After adopting foretell structure, solved because of the too big production, transportation, the project installation difficult problem that leads to the high too high production that brings of inspection shaft well room of trunk line bore, reduced the production degree of difficulty of well room, convenient transportation and the transfer among the project installation, the assembly is simple convenient, and assembly structure stability is good.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
