Abstract
The utility model provides a telescopic protection pit shaft of multistage, it wherein, is equipped with the external screw thread including interior pit shaft, outer pit shaft on the interior pit shaft outer wall, be equipped with the internal thread that closes with outer thread to match on the outer pit shaft inside wall, and interior pit shaft passes through on the internal thread that the external screw thread meshed pit shaft outside, interior pit shaft inner chamber bottom is equipped with prevents that the air crash constructs, is equipped with the helical shape climbing basin that advances to cardiac prominence in the section of thick bamboo on the interior pit shaft intracavity lateral wall, and every certain distance sets up a level and steps on the platform on the climbing basin, and the level is stepped on a surface and is equipped with non -slip raised, and the cross section top that platform and climbing basin were stepped on to the level all is recessed U -shaped or arc. Adopt the climbing basin can prevent that the big flood from producing the cavity negative pressure and exploding the well, carry out the water conservancy diversion to the big flood, scramble the basin simultaneously and adopt cross -section arc structure, in the time of when personnel fall into the well in, can hold in hand and scramble the basin and climb also the well head and save oneself.
Description
Technical field
This utility model relates to inspection shaft field, refers in particular to a kind of Multi-section telescopic formula protection pit shaft.
Background technology
Inspection shaft is used in the range of residential area, one residential, public building district, plant area etc. that buried plastics pipe road external diameter is not more than 800mm, the depth of burying is not more than 6m, be generally located at drainage pipeline intersection, turning, caliber or gradient change, at drop etc., for the ease of make regular check on, clean and dredge or the plastics integrated injection molding of inspection of down-hole operation form or brick become well shape structures.Existing well lid is to use concrete to cast or cast iron manufacture mostly, the weight of concrete manhole cover is at 70 to 90 kilograms, uncap difficulty, accidentally will break into pieces or hurt sb.'s feelings when closing lid, although casting iron well lid does not weighs, but casting iron well lid can send the biggest sound when vehicle rolls, produce noise, sound and noise that particularly night produces more make overlooking resident the most impacted, and the poor toughness of cast iron casting well lid, get rusty easily, and the most stolen, the most stolen rear supplement will result in car accident and personal injury not in time.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, anti-fall telescopic multisection type protection pit shaft.
For achieving the above object, technical scheme provided by the utility model is: a kind of Multi-section telescopic formula protection pit shaft, it includes interior pit shaft, outer shaft wall, wherein, interior pit shaft is positioned at the top, and interior pit shaft inner cavity top is provided with stair-stepping well lid retainer ring, and interior pit shaft outer wall is provided with external screw thread, outer shaft wall medial wall is provided with the female thread matched with external screw thread, and interior pit shaft is engaged on the female thread of outer shaft wall by external screw thread；Interior pit shaft intracavity bottom is provided with anti-fall mechanism, anti-fall mechanism uses criss-cross reinforcing bar to be skeleton, fiber rope net it is equipped with on skeleton, interior pit shaft intracavity sidewall is provided with the spiral climbing tank that cardiac prominence in cylinder is entered, on climbing tank, a horizontal horse block is set at a certain distance, horizontal horse block surface is provided with anti-skidding projection, and the cross-sectional top of horizontal horse block and climbing tank is all in recessed U-shaped or arc.
Described outer shaft wall is multiple, and the outer shaft wall outer wall being positioned at mid portion is provided with connection screw thread.
Described outer shaft wall internal diameter is more than or equal to interior pit shaft external diameter.
Described anti-fall mechanism is many groups, lays respectively at bottom interior pit shaft and outer shaft wall.
The utility model has the advantage of:
After manhole cover is lost or damaged, anti-drop net may also operate as protecting the effect fallen, it is ensured that pedestrian and vehicle safety.
When running into the well head that the degree of depth differs, can as required pit shaft be adjusted, to ensure that pit shaft is positioned at optimal length.
Using climbing tank can prevent flood from producing hollow negative pressure and quick-fried well, flood carries out water conservancy diversion, climbing tank uses cross section arcuate structure simultaneously, when personnel fall in well, can grab climbing tank with hands and climb also well head and save oneself.
Employing horizontal horse block is trampled when being used for saving oneself, and has the effect of anti-skidding support simultaneously.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is schematic cross-section of the present utility model.
Detailed description of the invention
Below in conjunction with all accompanying drawings, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1 and accompanying drawing 2, Multi-section telescopic formula protection pit shaft described in the present embodiment includes interior pit shaft 1, outer shaft wall 2, wherein, interior pit shaft 1 is positioned at the top, interior pit shaft 1 inner cavity top is provided with stair-stepping well lid retainer ring 8, interior pit shaft 1 outer wall is provided with external screw thread, outer shaft wall 2 internal diameter is more than or equal to interior pit shaft 1 external diameter, outer shaft wall 2 medial wall is provided with the female thread matched with external screw thread, and interior pit shaft 1 is engaged on the female thread of outer shaft wall 2 by external screw thread；Interior pit shaft 1 intracavity bottom is provided with anti-fall mechanism 3, anti-fall mechanism 3 uses criss-cross reinforcing bar to be skeleton, fiber rope net 7 it is equipped with on skeleton, interior pit shaft 1 intracavity sidewall is provided with the spiral climbing tank 5 that cardiac prominence in cylinder is entered, on climbing tank 5, a horizontal horse block 6 is set at a certain distance, horizontal horse block 6 surface is provided with anti-skidding projection, and the cross-sectional top of horizontal horse block 6 and climbing tank 5 is all in recessed U-shaped or arc.Being actually needed according to well depth, can be set to multiple by outer shaft wall 2, outer shaft wall 2 outer wall being positioned at mid portion is provided with connection screw thread.According to degree of protection, can be many groups by anti-fall mechanism 3, lay respectively at bottom interior pit shaft 1 and outer shaft wall 2.This programme it is a technical advantage that when manhole cover lose or damage after, anti-drop net may also operate as protecting the effect fallen, it is ensured that pedestrian and vehicle safety.When running into the well head that the degree of depth differs, can as required pit shaft be adjusted, to ensure that pit shaft is positioned at optimal length.Using climbing tank can prevent flood from producing hollow negative pressure and quick-fried well, flood carries out water conservancy diversion, climbing tank uses cross section arcuate structure simultaneously, when personnel fall in well, can grab climbing tank with hands and climb also well head and save oneself.Employing horizontal horse block is trampled when being used for saving oneself, and has the effect of anti-skidding support simultaneously.
The embodiment of the above is only the preferred embodiment of this utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to this utility model, principle are made, all should contain in protection domain of the present utility model.
