Description
Technical field
The utility model relates to municipal rain sewage works field, particularly relates to a kind of protection sink hole.
Background technology
Some inspection shafts often can be set in the sewage conduct below urban road to carry out the dredging of pipeline.Inspection shaft port is provided with inspection well cover, the material of inspection well cover be generally cast iron or steel concrete is made.The inspection well cover low price of steel concrete cast, but structural strength is poor, is difficult to the impact standing vehicle for a long time, is used on sidewalk or square more.The inspection well cover sound construction of cast iron, can carry larger pressure and impact force, uses comparatively extensive, but easily stolen.
Inspection well cover is stolen or after damaging, inspection shaft lacks protection, is prone to accidents, cause damage to vehicle and pedestrian, particularly in recent years, the fall event of inspection shaft of pedestrian often occurs, serious harm people's life and property safety, in order to avoid pedestrian falls inspection shaft, be provided with anti-drop net in part inspection shaft, but the pressure that anti-drop net can bear is little, and easily damage, durability extreme difference, often need better, cost is high, the carrying out of inconvenient maintenance work.
Utility model content
The technical problem that the utility model mainly solves be to provide well servicing under a kind of convenience, the sink hole of fall arrest stable performance.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of protection sink hole, comprise: basic straight tube and movable manhole cover, described movable manhole cover is arranged on the top of basic straight tube, the open outside at described basic straight tube top is provided with a clamping rings, described movable manhole cover is arranged in clamping rings, the bottom of described basic straight tube inwall is provided with the bracing frame that is pointed to inner side, be provided with one in described basic straight tube and wave cat ladder, described in wave cat ladder the front end of bottom and bracing frame be hinged.
In the utility model preferred embodiment, described basic straight tube is the brick cylinder or the pouring concrete cylinder that are vertically embedded in underground.
In the utility model preferred embodiment, side and the clamping rings of described movable manhole cover cylindrical are hinged.
In the utility model preferred embodiment, described in wave U-bend bar cat ladder being provided with several climbing.
In the utility model preferred embodiment, described in wave cat ladder top be positioned on the left of basic straight tube or on the inwall on right side.
The beneficial effects of the utility model are: the one protection sink hole that the utility model is pointed out, movable manhole cover and clamping rings are hinged, easy to use, add the difficulty of pilferage, and devise one especially and wave cat ladder, staff can be facilitated to go into the well and safeguard, wave after cat ladder is rocked to another side and stop, prevent the accidental falling of personnel, promote safety, practical.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is a kind of structural representation protecting sink hole one preferred embodiment of the utility model;
Fig. 2 is that in Fig. 1, parts 2 are rocked to the structural representation after another side.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 2, the utility model embodiment comprises:
A kind of protection sink hole, comprise: basic straight tube 1 and movable manhole cover 5, described movable manhole cover 5 is arranged on the top of basic straight tube 1, the open outside at described basic straight tube 1 top is provided with a clamping rings 4, when building basic straight tube, clamping rings 4 is connected with basic straight tube 1, sound construction and being not easily destroyed, described movable manhole cover 5 is arranged in clamping rings 4, the cylindrical of movable manhole cover 5 is corresponding with the inner circle of clamping rings 4, side and the clamping rings 4 of described movable manhole cover 5 cylindrical are hinged, under the support of clamping rings 4, movable manhole cover 5 can open and close flexibly, and both are connected as a single entity, movable manhole cover 5 is not easily destroyed or steals.
The bottom of described basic straight tube 1 inwall is provided with the bracing frame 3 that is pointed to inner side, is provided with one and waves cat ladder 2 in described basic straight tube 1, described in wave cat ladder 2 the front end of bottom and bracing frame 3 be hinged.Described top of waving cat ladder 2 is positioned on the left of basic straight tube 1 or on the inwall on right side.In Fig. 1, the top of waving cat ladder 2 is positioned on the inwall on the right side of basic straight tube 1, facilitate staff to go into the well and carry out maintenance work, and in Fig. 2, the top of waving cat ladder 2 is positioned on the inwall on the left of basic straight tube 1, can stop the object dropped down from basic straight tube 1 top, avoid it to fall further, effectively avoid the personnel of accidental fall to be engulfed by sewer pipe, promote protection safety.
Described basic straight tube 1 is the brick cylinder or the pouring concrete cylinder that are vertically embedded in underground, sound construction, and during construction, bracing frame 3 right-hand member is embedded on the right side of basic straight tube 1 in wall, and sound construction, not easily gets loose, good to the supportive of waving cat ladder 2.
Describedly wave U-bend bar cat ladder 2 being provided with several climbing, U-bend bar facilitates the climbing of personnel, and effectively accepts human body, stops landing.
In sum, the one protection sink hole that the utility model is pointed out, the theftproof performance of movable manhole cover 5 is good, maintains easily construction, and avoid personnel's accidental fall and being drowned of producing and relative inexpensiveness, stability is high, improves security performance.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
