Here, which includes several pit shafts mutually spliced.Each pit shaft includes pit shaft ontology 20, is set to pit shaft
21 are marked time in the inner cavity of ontology 20, and shown in Figure 2, it 21 is to be recessed inwardly to be formed by the lateral wall of well bore 2 that this, which is marked time, is marked time
21 have it is multiple, it is multiple mark time 21 intersect, being distributed on the inner sidewall of well bore 2 of being spaced, marking time 21 includes horizontally disposed
Tyre tread, the arc support being supported below tyre tread and the anti-skidding muscle (not shown) between tyre tread and support portion, should
Anti-skidding muscle is formed after being folded upward at by the junction of tyre tread and support portion, mark time 21 with pit shaft ontology 20 integrated molding set
It sets.Here, it is additionally provided with clamping portion on the pit shaft, for two adjacent pit shafts to be connected together, which includes being set to
Insertion section 22 in the upper port of pit shaft, the annular slot (not shown) on the lower port inner sidewall of pit shaft, insertion
Portion 22 is matched with card slot shape, size.
Here, by the way that well bore 2 to be arranged to mutually be spliced by multiple pit shafts, the transport and peace of inspection shaft have been convenient for it
Dress.And setting marks time 21 in pit shaft ontology 20, be conducive to operator climbs in inspection shaft, and the setting on 21 of marking time is anti-
Sliding muscle, having not only acted as prevents operator during climbing there is a phenomenon where skidding, while also acting as the effect of handgrip.?
The clamping portion being mutually clamped is set on pit shaft, so that after 2 assembly of well bore, the feelings that will not be leaked between two adjacent pit shafts
Condition.
In this example, which further includes several first reinforcing ribs 23 being set on the inner sidewall of pit shaft ontology 20, is set to well
Several second reinforcing ribs 24 on the lateral wall of cylinder ontology 20, it is shown in Figure 2.First reinforcing rib 23 includes being set to pit shaft sheet
Strip reinforcing rib that axial direction on the inner sidewall of body 20, along pit shaft ontology 20 extends and in pit shaft ontology 20
Ring stiffener on side wall, with the setting of 20 coaxial inner conductor of pit shaft ontology.Second reinforcing rib 24 includes being set to pit shaft ontology 20
Lateral wall on, along pit shaft ontology 20 axial direction extend strip reinforcing rib and set on the lateral wall of pit shaft ontology 20
Ring stiffener upper, with the setting of 20 coaxial inner conductor of pit shaft ontology.By the way that above-mentioned reinforcing rib is arranged, the intensity of pit shaft is improved.
In this example, the pedestal 3 of the inspection shaft include include bottom end closure base body 30 and be set to base body 30
All side walls on, four by-pass connections 31 facing each other, shown in Figure 4, all by-pass connections 31 are in sealing design.Institute
There are by-pass connection 31 and the inner cavity of base body 30 to communicate, the upper end aperture of base body 30, the bottom end of base body 30
Deposit cavity 33 is provided between the lower end surface of by-pass connection 31, it is shown in Figure 4, it also is provided with inserting on the upper end of base body 30

The junction of the inner cavity of seat ontology 30 is provided with blocking part 32, shown in Figure 4, when blocking part 32 is used for bypass pipe grafting, supports
Gear is in the insertion end of bypass pipe.
By the way that four by-pass connections 31 are arranged, operator can carry out aperture to by-pass connection 31 according to actual needs to connect
Connect bypass pipe.And deposit cavity 33 is set on the bottom end of base body 30 and is facilitated while ensuring not silting bypass pipe
Operator carries out dredging to deposit cavity 33.
In this example, by the way that blocking part 32 is arranged, so that keeping out in the insertion end of bypass pipe, having in grafting bypass pipe
It is effectively fixed conducive to being carried out to bypass pipe.Specifically, the blocking part 32 is in semicircular arc, the blocking part 32 is by by-pass connection 31
The inward-facing recess formation of side wall lower ends upper, close to 30 side of base body.
In this example, it is not less than pedestal sheet to the pipe wall thickness between blocking part 32 from insertion end port on the by-pass connection 31
1.5 times of the side wall wall thickness of body 30.By thickening the thickness of by-pass connection 31, so that the by-pass connection 31 is in grafting bypass pipe
When, it can be ensured that the installation strength of by-pass connection 31.
Here, ring flange 4 is equipped on the well head of inspection shaft 1, pit shaft, pedestal 3, it is shown in Figure 1, it is used for adjacent two
Installation between a component.Lifting lug 5 is additionally provided on the lateral wall of well head 1, referring to shown in Fig. 1,3, for lifting, in order to enhance well
Mouthful 1 intensity also has equipped with reinforcing rib on the inner sidewall and lateral wall of the well head 1.
In this example, the well head 1 of the inspection shaft includes the wellhead body 10 with hollow cavity, shown in Figure 3, well head sheet
It also is provided with marking time 21 in the inner cavity of body 10.21 are marked time by setting, allow the operator to facilitate disengaging well head 1.
The wellhead body 10 includes the cylindrical portion 101 set gradually along the vertical direction and flare 102, shown in Figure 3,
Institute's flare 102 is located on 101 lower end of cylindrical portion, gradually opens from top to bottom, and well head 1 passes through flare 102 and 2 phase of well bore
Even.By the way that the wellhead body 10 is divided into cylindrical portion 101 and flare 102, the production raw material of well head 1 is not only reduced, is passed through
Flare 102 is set, the lower end of cylindrical portion 101 can smoothly be extended into and be connected to each other with well bore 2, improve the peace of well head 1
Fill intensity.
In this example, which is three-decker, is followed successively by anticorrosive PTFE layer from inside to outside, polyurethane is protected
Warm layer and polyethylene anti-aging layer.The well head 1, pedestal 3 and pit shaft ontology 20 are made with material.By using above-mentioned material system
At well bore 2, well head 1 and pedestal 3, so that the intensity of the inspection shaft is high, good corrosion resistance.
