Description
Technical field
The utility model relates to a kind of structural shape of production waste inspection shaft, in particular to a kind of steel construction production waste
Inspection shaft belongs to the underground pipe network technical field of the projects such as petrochemical industry, coal chemical industry, light industry, metallurgy.
Background technique
Production waste inspection shaft is the essential row of underground pipe network of the projects such as petrochemical industry, coal chemical industry, light industry, metallurgy
Water structures must be provided with inspection shaft between 30~40m of each crosspoint or rectilinear duct of drainage pipeline.
Traditional underground pipe network production waste inspection shaft is generally brick, three kinds of concrete, reinforced concrete structure structures
Pattern；Wherein, brickwork construction production waste inspection shaft is because its leakage is serious, not durable has not used now.Concrete structure
Production waste inspection shaft: material is mainly cement, sand；There is more complex, construction climate of constructing to influence big, digging in-situ for it
The disadvantages of amount is big and construction period is longer, and leakage is more serious, needs frequent maintenance, well service life is short.Armored concrete knot
Structure production waste inspection shaft: material is mainly cement, sand, reinforcing bar；Its with easy to leak, maintenance relatively frequently, construction is complicated, applies
Work climate influences the disadvantage big, long construction period, digging in-situ amount are big, well service life is shorter.
As country is tight to becoming for environmental requirement, do not allow to penetrate into soil containing poisonous and hazardous sewage, to prevent from polluting
Soil and underground water.And the sewage of the industries such as chemical industry, oil refining, light industry, metallurgy discharge contains different degrees of poisonous and harmful dirt
Contaminate object.The production waste gully of existing factory is essentially reinforced concrete well, requires to have done while in accordance with national regulation stringent
Seepage control measure, but there is different degrees of leakage in the production waste inspection shaft of nearly all chemical project, give later maintenance
Increase certain difficulty.
Summary of the invention
In view of the above problems, the object of the present invention is to provide a kind of antiseep, easy construction, steel with long service life
Structure production waste inspection shaft, the inspection shaft digging in-situ amount is small, and weatherproof of constructing greatly shortens construction period, drops
The comprehensive cost of low inspection shaft.
To achieve the above object, the utility model use following technical scheme, a kind of steel construction production waste inspection shaft,
Be characterized in that: including the pit shaft made of steel plate or steel-pipe welding, there are manhole, the manholes for the top side of the pit shaft
On be covered with well lid, the sealed bottom of the pit shaft, the pit shaft is connected to inlet and outlet pipes respectively.
Ladder is vertically arranged on the inner wall for the pit shaft being located at below the manhole.
Annular cage is set in the top surrounding of the manhole, the internal perisporium of the annular cage has step cutting pattern, institute
It states well lid to be placed on the annular cage, and the outer peripheral edge of the well lid rides on the step cutting pattern of the cage.
Ring sets primary antibody water wing on the periphery wall in the middle part of the close pit shaft.
Gasket is respectively provided in the junction of the water inlet line, outlet conduit and pit shaft.
The pit shaft and manhole are integrally formed, and the diameter of the pit shaft is 1000~1200mm, the diameter of the manhole
For 700mm.
The pit shaft, manhole, inlet and outlet pipes inside and outside wall on be provided with corrosion resistant layer, the well lid uses
Resistant material is made.
Because the utility model adopts the above technical scheme, it has the following advantages: the sewage inspection well of the utility model
Pit shaft is formed using steel plate or steel-pipe welding, there is good leakage performance, pit shaft can the factorial production, overcome the prior art
Site operation complexity and meteorotropic defect, while excavated volume needed for scene is reduced, and then greatly shortens applying for inspection shaft
The work period reduces the comprehensive cost of inspection shaft.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the utility model provides a kind of steel construction production waste inspection shaft, it includes using steel plate or big
Pit shaft 1 made of bore steel-pipe welding, there are manhole 2, the sealed bottom of pit shaft 1, the conjunctions of 2 upper cover of manhole for the top side of pit shaft 1
There is well lid 3, pit shaft 1 is connected to water inlet line 4 and outlet conduit 5 respectively.
In above-described embodiment, inspection shaft is passed in and out for convenience of inspection personnel, is erected on 1 inner wall of pit shaft being located at below manhole 2
Straight setting ladder 6.
In above-described embodiment, in the annular cage 7 of top surrounding setting one of manhole 2, the internal perisporium of cage 7 has round platform
Rank, well lid 3 is placed on annular cage 7, and the outer peripheral edge of well lid 3 rides on the step cutting pattern of cage 7, makes well lid 3 easily
On Gai Heyu manhole 2, and it ensure that the leakproofness between manhole 2 and well lid 3.
In above-described embodiment, for guarantee pit shaft 1 it is stable be set to underground, the ring on the periphery wall close to the middle part of pit shaft 1
If primary antibody water wing 8.
In above-described embodiment, to guarantee leakproofness that water inlet line 4, outlet conduit 5 are connect with pit shaft 1, in water inlet line
4, the junction of outlet conduit 5 and pit shaft 1 is respectively provided with gasket 9.
