Abstract
The utility model provides a strenghthened type pit shaft that stretches out and draws back, it comprises the inside and outside pit shaft that registrates each other, wherein, interior pit shaft inner chamber bottom is equipped with prevents that the air crash constructs, be equipped with on the interior pit shaft intracavity lateral wall to section of thick bamboo center bellied helical shape climbing basin, every certain distance sets up a level and steps on the platform on the climbing basin, the level is stepped on a surface and is equipped with non -slip raised, all be equipped with the strengthening rib in the section of thick bamboo wall of inside and outside pit shaft, be equipped with the external screw thread on the interior pit shaft lateral wall, be equipped with the internal thread that closes with outer thread to match on the outer pit shaft inside wall, interior pit shaft passes through on the internal thread of external screw thread meshing pit shaft outside. The utility model discloses an air crash of seting up defences in the pit shaft constructs, even damage for some reason or be stolen, prevents that the air crash structure can prevent effectively also that the pedestrian from weighing down the well accident, increases people's personal safety.
Description
Technical field
This utility model relates to inspection shaft technical field, refers in particular to a kind of reinforced flexible 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, intensity are high, be applicable to the inspection shaft of the various degree of depth stretches pit shaft.
nullFor achieving the above object，Technical scheme provided by the utility model is: a kind of reinforced flexible pit shaft，It is made up of the interior outer shaft wall of mutual fit，Wherein，Interior pit shaft inner cavity top is provided with spiral helicine well lid locking ring，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 to cylinder central protuberance，On climbing tank, a horizontal horse block is set at a certain distance，Horizontal horse block surface is provided with anti-skidding projection，The cross-sectional top of horizontal horse block and climbing tank is all in recessed U-shaped or arc，It is equipped with reinforcement in the barrel of interior outer shaft wall，Described reinforcement is formed by some bamboo reinforcements or steel band are uniform or use spiral bamboo reinforcement or steel band to constitute，Interior pit shaft lateral wall is provided with external screw thread，Outer shaft wall medial wall is provided with the female thread matched with external screw thread，Interior pit shaft is engaged on the female thread of outer shaft wall by external screw thread.
Described reinforcement cross section is T-shaped, N-shaped or square.
The utility model has the advantage of:
The first, using stretch mode, the inspection going for the various degree of depth is looked into well, is significantly increased the range of pit shaft, uses spiral helicine well lid locking ring can be effectively increased the theftproof performance of well lid.
The second, set reinforcement in barrel, be greatly reinforced pit shaft intensity, extend the service life of pit shaft.
3rd, setting up defences in pit shaft air crash structure, even if well lid damages or stolen for some reason, anti-fall mechanism also can effectively prevent pedestrian's falling accident, increases the personal safety of people.
4th, using climbing tank i.e. to 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.
5th, 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 the interior pit shaft top view in Fig. 1.
Detailed description of the invention
nullBelow 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，Reinforced flexible pit shaft described in the present embodiment by the interior outer shaft wall 1 of mutual fit、2 are constituted，Wherein，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 to cylinder central protuberance，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，The cross-sectional top of horizontal horse block 6 and climbing tank 5 is all in recessed U-shaped or arc，Interior outer shaft wall 1、Reinforcement 4 it is equipped with in the barrel of 2，Reinforcement 4 cross section is T-shaped、N-shaped or square，Described reinforcement 4 is formed by some bamboo reinforcements or steel band are uniform or use spiral bamboo reinforcement or steel band to constitute，Interior pit shaft 1 lateral wall is provided with external screw thread，Outer shaft wall 2 medial wall is provided with the female thread matched with external screw thread，Interior pit shaft 1 is engaged on the female thread of outer shaft wall 2 by external screw thread.This programme uses stretch mode, and the inspection going for the various degree of depth is looked into well, significantly increased the range of pit shaft.Set reinforcement in barrel, be greatly reinforced pit shaft intensity, extend the service life of pit shaft.Setting up defences in pit shaft air crash structure, even if well lid damages or stolen for some reason, anti-fall mechanism also can effectively prevent pedestrian's falling accident, increases the personal safety of people.
Using climbing tank i.e. to 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.
