Abstract
The utility model discloses a prevent subsiding well lid, including well lid, well seat and adjusting collar, well seat root has well seat retaining ring, and the well lid is located at the heavy bench of the annular of well seat, its characterized in that: the adjusting collar diameter is less than well seat retaining ring diameter, is located well seat retaining ring. This prevent subsiding well lid installs the back, and well seat retaining ring is direct to be contacted with road bed cement, makes the mechanical properties of well seat better, and the retaining ring is difficult to produce the fracture and subsides and cause the deformation of well seat, has improved the life of security and well lid.
Description
Technical field
This utility model is related to well lid, and in particular to a kind of anti-settling manhole cover.
Background technology
The adjusting set of existing well lid is directly connected with roadbed cement with diameter greater than well seat back-up ring diameter, and well seat back-up ring is because of position
In adjusting set, it is impossible to directly contact with roadbed, due to having gap between well seat back-up ring and adjusting set.When heavy-duty vehicle is rolled
When, well seat is under pressure to produce tired bending in stress point, cause well seat fracture of root and produce sedimentation, cause well seat deformation etc.
Potential safety hazard.
The content of the invention
According to the deficiencies in the prior art, this utility model provides one kind and can reduce and avoid the deformation of well seat back-up ring and well seat
Fracture of root, and the anti-settling manhole cover of well lid service life can be improve.
For achieving the above object, the anti-settling manhole cover that this utility model is provided includes well lid, well seat, adjusting set, the well
Seat root has well seat back-up ring, and well lid is positioned on the heavy platform of the annular of well seat；It is characterized in that：The diameter of the adjusting set is less than
The diameter of well seat back-up ring, and be located in well seat back-up ring.
The good effect that this utility model is produced due to taking said structure is significant, i.e., due to well seat back-up ring diameter
More than adjusting sleeve, after installation, the structure that directly can be connected with roadbed cement makes well seat back-up ring be not easy to produce when being under pressure
Raw fracture sedimentation, and the deformation of well seat, substantially increase the service life of safety and well lid.
Description of the drawings
Fig. 1 is anti-settling manhole cover sectional view
In accompanying drawing：1- well seats, 2- well lids, 3- adjusting sleeves, 4- roadbed cement, 1.1- well seat back-up rings.
Specific embodiment
Such as Fig. 1, shown anti-settling manhole cover, including well lid 2, well seat 1 and adjusting set 3, the well seat root have well seat
Back-up ring 1.1, well lid 2 is positioned on the heavy platform of the annular of well seat 1；It is characterized in that：3 diameter of the adjusting set is less than well seat back-up ring
1.1 diameters, positioned at well seat back-up ring 1.
Further, the well lid is connected through the hinge with well seat or chase mortise is connected.
Further, the lockset being provided with well lid by Manhole cover lock on well seat.
The lockset is mechanical lockset, in addition to the existing mechanical lockset that well lid is locked with well seat, preferably：Institute
Mechanical lock is stated for mechanical code lock, such as the well lid mechanical lock of Patent No. 201410340695.8.
After above-mentioned anti-settling manhole cover is installed, well seat back-up ring 1.1 is directly contacted with roadbed cement 4, and mechanical property more preferably, makes well
Seat back-up ring does not allow to be also easy to produce when being under pressure fracture sedimentation, causes well seat to deform, and substantially increases safety and well lid
Service life.
