The inspection well ladder comprises a dual-layer ring base arranged at an opening of an inspection well, wherein a plurality of supporting screen mechanisms for supporting the dual-layer ring base and providing the dual-layer ring base at a wellhead are arranged on the bottom end face of the dual-layer ring base; the inspection well ladder also comprises a crawling ladder which is suspended on the dual-layer ring base and extends into the inspection well; the crawling ladder is connected with each layer of ring of the dual-layer ring base. By adopting the inspection well ladder, the crawling ladder can be stably arranged at the wellhead, inconvenience for coming in and going out the inspection well caused by inclined crawling ladder can be avoided, the problem of shaking when the suspended crawling ladder is used also can be avoided, and the inspection well ladder has good practicability.
Description
Technical field
The utility model relates to a kind of cat ladder, relates in particular to a kind of Municipal Engineering Construction inspection well ladder.
Background technology
A lot of pipe-lines in municipal engineering and facility are all laid in underground passage, and inspection shaft is as unique access of lower channel communicatively, in Municipal Engineering Construction frequently for constructor's turnover.In existing inspection shaft, mostly on the borehole wall, be fixedly installed multistage cat ladder, but these cat ladders tend to occur the loosening situation not firm and that corrosion causes structural strength to reduce of fixing be easy to cause the generation of fallen accident through after a period of time.For preventing causing accidental fall because borehole wall cat ladder is loosening and when the borehole wall does not have the situation of cat ladder, constructor shaves bamboo ladder or aluminium alloys to be inclined in inspection shaft often, for the inspection shaft of coming in and going out.This tilting bamboo ladder or aluminium alloys are shaved on the one hand and are unfavorable for moving up and down of constructor, are also unfavorable on the other hand in work progress, catch pit port being blocked.
Utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of Municipal Engineering Construction inspection well ladder, it can make cat ladder firmly arrange at catch pit port, can avoid the tilting inconvenience that causes the inspection shaft of coming in and going out of cat ladder, and the cat ladder of also can avoiding suspending rocks the generation of problem in use, has good practicality.
For achieving the above object, this Municipal Engineering Construction comprises the double-layer circular ring seat that is arranged on inspection shaft well head with inspection well ladder, be provided with the described double-layer circular ring seat of a plurality of supports and make double-layer circular ring seat be positioned in the support clamping mechanism on well head on the bottom face of double-layer circular ring seat; Also comprise and be hung in double-layer circular ring seat and stretch into the cat ladder in inspection shaft, described cat ladder all hangs and is connected with every layer of annulus of double-layer circular ring seat.Adopt above-mentioned technical scheme, by supporting clamping mechanism, double-layer circular ring seat supports is placed on to well head and is positioned on well head, then cat ladder being hung in double-layer circular ring seat can be by the cat ladder inspection shaft of coming in and going out.Owing to supporting clamping mechanism support screens to double-layer circular ring seat at well head place, make the movement that can not meet accident of double-layer circular ring seat, guaranteed to hang the stability of cat ladder thereon, cat ladder vertically hanging in double-layer circular ring seat also avoided the inconvenience of the discrepancy inspection shaft that tilting cat ladder causes, and because cat ladder all hangs and is connected with every layer of annulus of double-layer circular ring seat, also make cat ladder obtain multipoint positioning in double-layer circular ring seat, in use with regard to the problem that can not shake.
As the restriction to aforesaid way, described support clamping mechanism is distributed on the bottom face of double-layer circular ring seat.Support clamping mechanism is evenly arranged and can makes it more stable to the support of double-layer circular ring seat and screens, and also make inspection well ladder structure attractive in appearance.
As the restriction to aforesaid way, described support clamping mechanism comprises the joint pin that is fixed on double-layer circular ring seat bottom face, the gripper shoe that is connected with joint pin bottom and stretches to double-layer circular ring seat outside, and be vertically fixed on described gripper shoe near the fixture block on the termination of double-layer circular ring seat inner side.Joint pin can make double-layer circular ring seat exceed well head bottom surface certain distance, so that cat ladder hanging on bottom annulus; Gripper shoe can make double-layer circular ring seat obtain wider firm support at well head place, avoids because of joint pin only at shaft mouth side along the stressed shaft mouth side that causes among a small circle along the slump on ground; Fixture block can make the screens of double-layer circular ring seat in well head, has avoided double-layer circular ring seat, at well head place, unnecessary movement occurs.
As the restriction to aforesaid way, in the folding lateral bracket that is provided with in the bottom of described cat ladder.Arrange when lateral bracket can have ponding in shaft bottom constructor is stood thereon, when workload is less in well, can reduce unnecessary trouble.
As the restriction to aforesaid way, in described double-layer circular ring seat, rotate and be provided with cover plate with holes.Cover plate with holes is set in double-layer circular ring seat, both can have prevented that object from surprisingly falling into inspection shaft, also guaranteed the light in inspection shaft.
In sum, adopt the technical solution of the utility model, can make cat ladder firmly arrange at catch pit port, can avoid that cat ladder is tilting causes the inconvenience of inspection shaft of coming in and going out, and the cat ladder of also can avoiding suspending rocks the generation of problem in use, there is good practicality.
